Na contemporaneidade, o planejamento e a gestão de bacias hidrográficas assumem importância cada vez maior. Segundo Santos (2004), a bacia hidrográfica pode ser compreendida como uma área drenada por um rio principal e seus afluentes, constituindo, portanto, um recorte espacial. As intervenções exercidas em todo o mundo e, sobretudo na Amazônia, nas bacias hidrográficas têm produzido efeitos e consequências negativas que merecem atenção e análise. Nesse contexto, o presente artigo faz uma análise do uso do recurso água na bacia hidrográfica do Rio Mojuí, situado na região do planalto santareno porção oeste do Pará. Para tanto, a metodologia adotada partiu do levantamento teóricoconceitual, coleta de dados em campo, processamento de dados orbitais e aplicação de planilha de campo, principalmente. De um modo geral o trabalho constitui um esforço de sistematização de dados e informações de uma área inserida num contexto de expansão da agricultura mecanizada e consolidação territorial, no que tange aos limites municipais do recém-instalado município de Mojuí dos Campos.

O presente trabalho tem arrimo no fato de que o assédio moral nas relações de trabalho é um problema social grave e pouco discutido em meio à sociedade em geral, sendo, muitas vezes, ignorado ou encoberto pela própria vítima por ter medo de perder o emprego ou pela vergonha de ser desprezado pelos demais colegas de trabalho. O referido assunto tem adquirido relevo por pesquisadores de diversas áreas do conhecimento como Sociologia, Administração de Empresas, Psicologia, Direito e outras. Por tal razão, o que aqui se visa é contribuir para a discussão do tema, realizando-se uma reflexão sobre o assédio moral como fator de degradação do meio ambiente laboral, assim como diante do dano reflexo causado à vida pessoal, familiar e social do trabalhador. Dessa forma, apresenta-se, sem a pretensão de esgotar o assunto, a forma como o direito estabelece a proteção ao meio ambiente do trabalho, consubstanciado na doutrina e jurisprudência pátria, notadamente, em observância ao comezinho princípio fundamental da dignidade da pessoa humana.

O objetivo do artigo é o de refletir sobre a experiência da diversidade sexual e de gênero no Pará, mais especificamente em Belém, a partir de três bases metodológicas: 1) a recensão bibliográfica sobre o tema elaborada na Universidade Federal do Pará, 2) a observação da configuração local do espaço público dos movimentos sociais de lésbicas, gays, bissexuais, travestis, transexuais, transgêneros e intersexuais e 3) a análise das representações e discursividades sobre as homossexualidades ali elaboradas. Palavras-chave: Diversidade Sexual e de Gênero. Espaço Público. Representações. Discursividades. Pará. ABSTRACT This aim of this article is the analys is of the experience of sexual and gender diversity in the Brazilian state of Pará, specially in its capital city, Belém, on the methodological basis of 1) the bibliographic al references writ ten by student sand researchers of the Federal University of Pará, 2) the observation of the local configuration of the public space of the LGBT social movements, and 3)the interpretation of the social representation sand the discursive tie son homosexualitys locally elaborated. Keywords: Sexual and gender diversity. Public Space. Representations. Discursivities. Pará.

Neste trabalho, buscamos analisar e compreender um conjunto de estratégias adotadas pelos camponeses de várzea da Ilha de São Miguel que foram fundamentais no processo de apropriação, delimitação e uso do território deste grupo, onde suas práticas espaciais têm fortalecido suas territorialidades, bem como lhes garantem não somente o controle dos recursos extrativos, mas também a construção de um território de uso exclusivo dos moradores da Ilha. O estudo foi desenvolvido obedecendo aos seguintes procedimentos de pesquisa: revisão bibliográfica, pesquisa documental e visita de campo. Os resultados indicam que, o território extrativo, hoje sobre controle e gestão dos camponeses de várzea da Ilha de São Miguel, é o resultado de uma luta coletiva e expressa formas de uso comum desta fração do espaço. E as estratégias de controle territorial são fundamentais para garantir a reprodução material e imaterial desse grupo de camponês, o que nos parece uma demonstração legítima de gestão do território.Palavras chaves: Território, camponês, várzea, gestão coletiva, resistência.TERRITORIALITIES AND RESISTANCE OF RIVERINE PEOPLE SANTARÉM MICROREGION –PARÁAbstractThis study aimed to analyze and to understand the strategies used by riverine people from Sao Miguel Island in the floodplain of the Amazon Basin. It was analyzed the strategies influencing processes of ownership, delimitation of areas, and land use, which spatial practices, strengthens territoriality, guarantees natural resources control, and determines an area of exclusive use for the residents of the island. The study was developed according to the search procedures: literature review, documental research and data sampling (fieldwork). This study showed that the extractive territory, currently being controlled and managed by riverine people of the São Miguel Island, is a result of a collective struggle and shows models of common use of that part of the space. The strategies of territorial control are essential to ensure the material and immaterial reproduction of the peasant group, which seems to be a legitimate demonstration of management of land.Keywords: Territory, peasant, floodplain, collective management, resistance.

As vilas rurais na Amazônia paraense se configuram como escala de análise geográfica, por apresentarem uma natureza humana, manifestada nas suas formas conteúdos, que lhes confere o caráter geográfico, sendo possível a categorização e conceituação das mesmas. O objetivo deste trabalho é compreender as vilas rurais conceitualmente a partir do olhar geográfico, bem como entender a organização espacial destas formas/conteúdos a partir das ações dos diferentes sujeitos sociais que agem nestes espaços apropriando-se e ao mesmo tempo construindo seus espaços de vivência e produção na Amazônia paraense. Para tanto, a teoria de produção social do espaço foi o referencial teórico que norteou a compreensão dos espaços dos camponeses, produtores, coletores e pescadores em questão. As informações utilizadas neste trabalho foram coletadas durante a realização de pesquisas de campo nas vilas de pescadores de Céu e Cajuuna, localizadas no município de Soure, na Ilha do Marajó e na vila de Agricultores e extrativistas de Santana do Urucuri, localizada no município de São Miguel do Guamá, ambas no estado do Pará. ABSTRACTThe rural villages in the Amazon Pará stand as geographic scale of analysis, because it has a human nature, manifested in its form and content, which gives them the geographical character, being possible a conceptualization and categorization of them. The objective of this work is to understand the rural villages conceptually from the look geographic as well as understand the spatial organization of these (forms and contents) from the actions of different social subjects who act appropriating these spaces while building their spaces of living and production in the Amazon state of Pará. Therefore, the theory of social production of space was the theoretical framework that guided the understanding of spaces of peasants, fishermen and gatherers in question. The information used in this paper were obtained while conducting field research in the fishing villages of Heaven and Cajuuna, located in the city of Soure, on Marajó Island and the village of farmers and gatherers of Santana's Urucuri, located in the municipality of São Miguel Guamá, both in the state of Pará.

Background: We hypothesized that a diet with old man saltbush hay used as an alternative source of nutrients could partially replace the concentrate in the feeding of feedlot lambs. Objective: This study evaluated the behavior and performance of lambs fed diets containing increasing levels of old man saltbush hay plus concentrate. Methods: Twenty-four castrated Santa Inês lambs at approximately eight months of age (22 ± 1.97 kg) were confined in a randomized complete design and fed diets containing 30, 40, 50, and 60% (dry matter: DM) of old man saltbush hay. Results: The intake of DM and neutral detergent fiber was not affected (p>0.05) by the level of old man saltbush hay. Intake of mineral salt decreased (p0,05) por los diferentes niveles de inclusión de hierba-sal. La ingestión de sal mineral se redujo (p0,05) pelos diferentes níveis de erva-sal. A ingestão de sal mineral reduziu (p

First described over 120 years ago in Brazil, Amazonian Dark Earths (ADEs) are expanses of dark soil that are exceptionally fertile and contain large quantities of archaeological artefacts. The elevated fertility of the dark and often deep A horizon of ADEs is widely regarded as an outcome of preColumbian human influence. Archaeological research provides clear evidence that their widespread formation in lowland South America was concentrated in the Late Holocene, an outcome of sharp human population growth that peaked towards 1000 BP.\ud In their recent paper Silva et al. argue that the higher fertility of ADEs is principally a result of fluvial deposition and, as a corollary, that pre-Columbian peoples just made use of these locales, contributing little to their enhanced nutrient status.\ud Soil formation is inherently complex and often difficult to interpret, requiring a combination of geochemical data, stratigraphy, and dating. Although Silva et al. use this combination of methods to make their case, their hypothesis, based on the analysis of a single ADE site and its immediate surroundings (Caldeirão, see maps in Silva et al.), is too limited to distinguish among the multiple possible mechanisms for ADE formation.\ud Moreover, it disregards or misreads a wealth of evidence produced by archaeologists, soil scientists, geographers and anthropologists, showing that ADEs are anthropic soils formed on land surfaces enriched by inputs associated with pre-Columbian sedentary settlement. To be accepted, and be pertinent at a regional level, Silva et al.’s hypothesis would need to be supported by solid evidence (from numerous ADE sites), which we demonstrate is lacking.

Em 2010, a Instrução Normativa IN/INCRA n° 65 limitou as alternativas de exploração indireta dos recursos florestais em assentamentos de reforma agrária, assim os riscos financeiros e operacionais recaíram sobre as comunidades beneficiárias, que além das dificuldades técnicas gerenciais ainda enfrentam conflitos agrários e tensões sociais. Nesse contexto, por meio da contabilidade de custos, e utilizando o estudo de caso do manejo florestal, implementado em 2016-2017 no PDS Virola-Jatobá, em Anapu, Pará, o objetivo deste estudo foi avaliar comparativamente o resultado financeiro, contábil e econômico do manejo florestal comunitário. A análise de custos, incluindo o custo de oportunidade de concessão da floresta em pé, indicou prejuízos financeiros (-34,72%) e econômicos (-129,75%), e que a melhor opção teria sido a exploração indireta por meio de concessão ou similar. Por outro lado, a exploração direta poderia alcançar lucro financeiro de 32,47% caso fosse assegurado valor de mercado para a madeira, conforme classificação comercial, e fossem evitadas perdas extraordinárias devido a invasões ocorridas Made available in DSpace on 2022-11-01T20:08:23Z (GMT).

The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Yet, forest patches do occur in the tropics where a single tree species is dominant. Such “monodominant” forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors.

Analyses of forest loss and protected areas suggest that 36 to 57% of Amazonian tree flora may qualify as “globally threatened.”, Estimates of extinction risk for Amazonian plant and animal species are rare and not often incorporated into land-use policy and conservation planning. We overlay spatial distribution models with historical and projected deforestation to show that at least 36% and up to 57% of all Amazonian tree species are likely to qualify as globally threatened under International Union for Conservation of Nature (IUCN) Red List criteria. If confirmed, these results would increase the number of threatened plant species on Earth by 22%. We show that the trends observed in Amazonia apply to trees throughout the tropics, and we predict that most of the world’s >40,000 tropical tree species now qualify as globally threatened. A gap analysis suggests that existing Amazonian protected areas and indigenous territories will protect viable populations of most threatened species if these areas suffer no further degradation, highlighting the key roles that protected areas, indigenous peoples, and improved governance can play in preventing large-scale extinctions in the tropics in this century.

PRS acknowledges the Faculty of Sciences, Universidad de los Andes, for financial support (INV-2021-128-2268). Aim : To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource‐availability hypothesis). Time period : Tree‐inventory plots established between 1934 and 2019. Major taxa studied : Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location : Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods : We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree‐inventory plots across terra‐firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance‐weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results : Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra‐firme forests (excluding podzols) compared to flooded forests. Main conclusions : The disperser‐availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types.

No. of bitstreams: 0 Previous issue date: 2022-01-01 The Atlantic Forest, a hotspot for biodiversity conservation, harbours five forest deer species (Mazama spp.). Due to their elusiveness, there is a severe scarcity of occurrence data to support ecological studies and conservation planning. Thus, we assembled an occurrence dataset of Atlantic Forest deer with reliable taxonomic information aggregating data from scat and camera traps surveys, and opportunistic data collection over the last 20 years. From 2002 to 2019, we surveyed 77 protected areas using scats detection dogs and genetically identifying the faecal samples. We successfully identified 1,147 out of 1,450 collected samples. From 2000 to 2020, we sampled six protected areas in 92 sampling points with 13,328 camera trap days of sampling effort. In addition, we established an active search for potential contributors within the scientific community and environmental consultants since 2010, offering a taxonomic identification service for camera traps images, and biological field-collected samples. With our efforts, we assembled a dataset with 1,456 records of forest deer occurrence at the Atlantic Forest. Of these records, 494 are from M. americana, 350 from M. bororo, 309 from M. gouazoubira, 268 from M. nana and 35 from M. nemorivaga. The faecal sampling was the most predominant method in these records (n = 1043) followed by photographs from camera traps (n = 388); both methods represent 98.2% of our dataset records. Most of the records (79.5%) in the dataset are inside protected areas (n = 1,130). Our dataset is the most comprehensive source of information on Neotropical forest deer occurrence to date.

The Golden Retriever muscular dystrophy (GRMD) is one of the best models of Duchenne muscular dystrophy (DMD), with similar genotypic and phenotypic manifestations. Progressive proliferation of connective tissue in the endomysium of the muscle fibers occurs in parallel with the clinical course of the disease in GRMD animals. Previous studies suggest a relationship between mast cells and the deposition of fibrous tissue due to the release of mediators that recruit fibroblasts. The aim of this study was to evaluate the presence of mast cells and their relationship with muscle injury and fibrosis in GRMD dogs of different ages. Samples of muscle groups from six GRMD and four control dogs, aged 2 to 8 months, were collected and analyzed. The samples were processed and stained with HE, toluidine blue, and Azan trichrome. Our results showed that there was a significant increase in infiltration of mast cells in all muscle groups of GRMD dogs compared to the control group. The average number of mast cells, as well as the deposition of fibrous tissue, decreased with age in GRMD dogs. In the control group, all muscle types showed a significant increase in the amount of collagenous tissue. This suggests increased mast cell degranulation occurred in younger GRMD dogs, resulting in increased interstitial space and fibrous tissue in muscle, which then gradually decreased over time as the dogs aged. However, further studies are needed to clarify the role of mast cells in the pathogenesis of fibrosis. RESUMO: O cão Golden Retriever distrófico (Golden Retriever muscular dystrophy - GRMD) é um dos melhores modelos da distrofia muscular de Duchenne (DMD), com manifestações genotípicas e fenotípicas similares. A proliferação progressiva de tecido conjuntivo no endomísio das fibras musculares ocorre paralelamente ao curso clínico da doença em animais GRMD. Estudos anteriores sugerem uma relação entre os mastócitos e a deposição de tecido fibroso devido à liberação de mediadores que recrutam fibroblastos. O objetivo deste estudo foi avaliar a presença de mastócitos e sua relação com a lesão muscular e fibrose em cães GRMD de diferentes idades. Amostras de grupos musculares de seis GRMD e quatro controles, com idade entre 2 a 8 meses, foram coletadas e analisadas. As amostras foram processadas e coradas com HE, azul de toluidina e tricrômico de Azan. Nossos resultados mostraram que houve um aumento significativo na infiltração de mastócitos em todos os grupos musculares de cães GRMD em comparação com o grupo controle. O número médio de mastócitos, assim como a deposição de tecido fibroso, diminuiu com a idade em cães GRMD. No grupo controle, todos os tipos musculares mostraram um aumento significativo na quantidade de tecido colágeno. Isto sugere o aumento da degranulação de mastócitos em cães GRMD mais jovens, resultando em aumento do espaço intersticial e tecido fibroso no músculo, que então gradualmente diminuiu com o tempo à medida que os cães envelheceram. No entanto, mais estudos são necessários para esclarecer o papel dos mastócitos na patogênese da fibrose.

Thus, identifying ecological thresholds is useful for defining regulatory limits and for guiding the management of riparian zones towards the conservation of freshwater biota. Using nationwide data on fish and invertebrates occurring in small Brazilian streams, we estimated thresholds of native vegetation loss in which there are abrupt changes in the occurrence and abundance of freshwater bioindicators and tested whether there are congruent responses among different biomes, biological groups and riparian buffer sizes. Mean thresholds of native vegetation cover loss varied widely among biomes, buffer sizes and biological groups: ranging from 0.5% to 77.4% for fish, from 2.9% to 37.0% for aquatic invertebrates and from 3.8% to 43.2% for a subset of aquatic invertebrates. Confidence intervals for thresholds were wide, but the minimum values of these intervals were lower for the smaller riparian buffers (50 and 100 m) than larger ones (200 and 500 m), indicating that land use should be kept away from the streams. Also, thresholds occurred at a lower percentage of riparian vegetation loss in the smaller buffers, and were critically lower for invertebrates: reducing only 6.5% of native vegetation cover within a 50-m riparian buffer is enough to cross thresholds for invertebrates. Synthesis and applications. The high variability in biodiversity responses to loss of native riparian vegetation suggests caution in the use of a single riparian width for conservation actions or policy definitions nationwide. The most sensitive bioindicators can be used as early warning signals of abrupt changes in freshwater biodiversity. In practice, maintaining at least 50-m wide riparian reserves on each side of streams would be more effective to protect freshwater biodiversity in Brazil. However, incentives and conservation strategies to protect even wider riparian reserves (~100 m) and also taking into consideration the regional context will promote a greater benefit. This information should be used to set conservation goals and to create complementary mechanisms and policies to protect wider riparian reserves than those currently required by the federal law.

A referência ao Ensino engloba as modalidades do ensino formal e do não formal. A proposta interdisciplinar na pesquisa trabalha com a concepção de integração entre saberes – e sabores (ANASTASIOU, 2015) –, para fortalecer a comunicação e a articulação entre as áreas em seus pontos convergentes, implicando partilhas teóricas, práticas e intersubjetivas. Nosso objeto de estudo é o Desenho, como linguagem, o ato de desenhar, riscar, traçar. Para muitos adultos, trata-se de uma atividade que precisa ser retomada, recuperada e/ou resgatada, pois, apesar da afirmação “não sei desenhar” ser frequente, na sociedade brasileira atual, não se caracteriza como um primeiro encontro entre as pessoas/adultos e o Desenho. A proposta foi inicialmente visualizada a partir da experiência vivida, no espaço não formal de ensino de Desenho. Definimos a fenomenologia de Husserl (2012) como pressuposto filosófico da pesquisa, porque, para a fenomenologia, o conhecimento não deve excluir o ser humano, a realidade vivida, portanto, a subjetividade. Nossas interrogações foram: O que é isto, o Desenho? O que é o Desenho para a Ciência? O que é o Desenho para o Ensino de Ciências?, para descrever a Ensinagem do Desenho para professores de Ciências, objetivo geral da dissertação. Buscamos, na experiência intersubjetiva, a compreensão do fenômeno e, desta forma, optamos por encontros no formato de oficinas, por serem espaços privilegiados para interações (MELO; MAIA; CHAVES, 2016). Além disso, encontramos na A/r/tografia uma metodologia de pesquisa baseada em Arte, que privilegia, na escrita, uma linguagem própria para o espaço intermediário e interdisciplinar, e que oferece o suporte metodológico para o estabelecimento de um ambiente teórico, permitindo a ampliação das percepções sobre o nosso tema. Por meio das aproximações neste espaço teórico, foi possível propor uma releitura para a proposta de Betty Edwards, um dos saberes no ensino de Desenho, a partir da fenomenologia da percepção de Merleau-Ponty (2020 [1945]). Desenvolveu-se a Oficina, e, na sequência, houve coleta de relatos dos participantes, docentes, discentes ou egressos dos cursos de licenciaturas em geral da UEPG, e programas de pós-graduações em ensino/Educação, que aceitaram voluntariamente participar da oficina de Percepção Visual do Desenho. Esses dados foram analisados na perspectiva fenomenológica. Os resultados se caracterizam como parte fundamental dessa pesquisa, mas não pretendem esgotar a temática, nem encerrá-la, indicam que o Desenho é uma importante ação-ferramenta que se relaciona simbioticamente com a Ensinagem de Ciências, além de constituir uma linguagem (DERDYK, 2020) historicamente constituinte do saber, que tem a capacidade de criar relações que promovem caminhos novos de ensino e aprendizagem. Considera-se também que há necessidade de revisão e de abertura para a discussão dos saberes em Desenho nesse campo. This research adopts an interdisciplinary view on Arts and Science, through Teaching matters, referring to formal and non-formal contexts. The interdisciplinarity approach integrates the knowledge and the emotions (ANASTASIOU, 2015) to strengthen the communication and articulation between the fields in its similar aspects, resulting in theoretical, practical and subjective exchange. Our study subject is Drawing/Draw as a language. It involves the action of drawing, sketching, tracing. For most of adults, it is an activity that needs to be recovered and/or rescued, even with the “I can‟t draw” statement and the frequency it is heard in Brazilian contemporary society, it won‟t be the first encounter among adults and drawing. The proposal was designed from the personal and teaching in the informal context experience. The philosophical approach involves Husserl (2012) phenomenology due to its capacity to consider not only the knowledge, but also the human being and his/her reality, as a subjective issue. Our questions are: What is this, drawing? What is drawing to Science? What is drawing to Science teaching?. We aim to describe the teaching and learning process of Drawing to Science teachers. Looking for an intersubjective experience of the phenomenon, we established workshops (“oficinas”, in Portuguese) as the place and opportunity to interact (MELO; MAIA; CHAVES, 2016). Besides, from the methodology A/r/tography the intermediate and interdisciplinary language supported the composition of a theoretical environment that allowed a broad perceptions over the theme. Within the approximations in this theoretical environment, we developed a new look and reading experience for Betty Edwards‟ proposal on drawing, with the phenomenology of perception by Merleau-Ponty (2020 [1945]). The workshop participants included teachers, students and alumni of undergraduate teaching courses and post-graduation on Education/Teaching, that volunteered and accepted taking part in the experience. The data analysis was phenomenological and the results, even though represent a significant part of the research, do not end or close the debate over the topics covered. They indicate that Drawing is an important action-tool that relates to the teaching and learning process of Sciences, and it is also a language (DERDYK, 2020) that historically follows the knowledge creation and acquisition. Drawing creates new teaching and learning paths and there is an investigation gap

Despite that, this biome still includes many areas that are poorly known floristically, including several protected areas, such as the Floresta Nacional do Rio Preto (Flona do Rio Preto), located in the Brazilian State of Espírito Santo. This study used a published vascular plant species list for this protected area from the Catálogo de Plantas das Unidades de Conservação do Brasil as the basis to synthesise the species richness, endemism, conservation and new species occurrences found in the Flona do Rio Preto. New information The published list of vascular plants was based on field expeditions conducted between 2018 and 2020 and data obtained from herbarium collections available in online databases. Overall, 722 species were documented for the Flona do Rio Preto, 711 of which are native to Brazil and 349 are endemic to the Atlantic Forest. In addition, 60 species are geographically disjunct between the Atlantic and the Amazon Forests. Most of the documented species are woody and more than 50% of these are trees. Twenty-three species are threatened (CR, EN and VU), while five are Data Deficient (DD). Thirty-two species are new records for the State of Espirito Santo. Our results expand the knowledge of the flora of the Atlantic Forest and provide support for the development of new conservation policies for this protected area.

The objective of this study is to evaluate the elephant grass silage with different levels of inclusion of açaí residue on the fermentative quality and aerobic stability. For this purpose 20 silos (SE) were made, 04 per treatment. The elephant grass and the residue of açaí berry were mixed at the time of the silage. The experimental design was completely in randomized design in five levels of inclusion, 0; 10; 20; 30 and 40% of industrial residue of açaí. The SE were opened in 30 days and samples were collected for bromatological analysis. The content of dry matter (DM) increased by 10.8% in 0 to 40% of silages of inclusion of the residue. At every 1% of added residue, organic matter content increased 0.063%. At temperatures of the silages there was linear reduction (P < 0.05) of 0.028% with the addition of the açaí residue of açaí. Silages with 20 and 30% of residue of açaí remained for a longer period within the ideal range of pH, 3.82 and 3.98 at 60 and 72 hours, respectively. Silages with 10, 20, 30, 40% presented the highest aerobic stability, because they reached 2° C elevation in relation to room temperature, with 12 hours of exposure to oxygen. However, the silage without inclusion of açaí residue remained stable for only 1 hour. All treatments with residue of açaí provided silages with sensory, fermentative features and MS content that tank them as having good quality, especially the treatment with 20% of açaí residue, as it presents the best results of the analyzed variables., El objetivo de esta investigación fue evaluar el ensilaje de hierba de elefante con diferentes niveles de inclusión de residuos de açaí en la calidad fermentativa y la estabilidad aeróbica. Para esto, se realizaron 20 silos experimentales (SE), 04 por tratamiento. La hierba de elefante y los residuos de açaí se mezclaron en el momento del ensilado. El diseño utilizado fue completamente al azar en cinco niveles de inclusión, 0; 10; 20; 30 y 40% de los residuos agroindustriales de açaí. Los SE se abrieron después de 30 días y se tomaron muestras para análisis bromatológicos. El contenido de materia seca (MS) aumentó hasta un 10,8% en ensilajes del 0 al 40% de inclusión del residuo. Por cada 1% de residuo agregado, el contenido de materia orgánica aumentó en un 0.063%. En las temperaturas de los ensilajes hubo una reducción lineal (P, Objetivou-se nesta pesquisa avaliar a silagem de capim-elefante com diferentes níveis de inclusão de resíduo de açaí sobre a qualidade fermentativa e a estabilidade aeróbia. Para isso foram confeccionados 20 silos experimentais (SE), 04 por tratamento. O capim-elefante e o resíduo de açaí foram misturados no momento da ensilagem. O delineamento utilizado foi inteiramente casualizado em cinco níveis de inclusão, 0; 10; 20; 30 e 40% do resíduo agroindustrial do açaí. Os SE foram abertos com 30 dias e colhidas amostras para análise bromatológica. O teor de matéria seca (MS) aumentou em até 10,8% nas silagens de 0 a 40% de inclusão do resíduo. A cada 1% de resíduo adicionado, o teor de matéria orgânica apresentou acréscimo de 0,063%. Nas temperaturas das silagens houve redução (P

Corn is among the short-cycle annual species used in agroforestry systems due to its adaptation to intercropping. Thus, this study aimed to evaluate the corn yield, cultivar BIO Z 2365, in two types of agroforestry systems. The experiment was carried out in a forestry agroforestry system in two treatments: mechanized with mineral fertilizer and semi-mechanized with organic fertilizer. The experiment was carried out in a forestry agroforestry system (AFSs), with two treatments, mechanized with mineral fertilizers (MEC) and semi-mechanized with organic fertilizers (SMEC). Each treatment was composed of four crop strips (4 x 24 m) distributed with plants arranged at a distance of 0.50 m between lines, totaling four plots per treatment. A random collection of 20 plants per strip was used, and different variables related to production were evaluated. The productivity was estimated using the EMATER and Reetz methods and by estimating the direct yield. The t-test was adopted to verify the difference between treatments. The mechanized system was superior for all the variables evaluated, obtaining average yield of 41.6 bags ha-1. In the semi-mechanized system, the average yield was 29.2 bags ha-1. The performance of cultivar BIO Z 2365 was better in the mechanized system. However, the results revealed that the cultivation of short-cycle crops, despite technological restrictions in the experimental area, can mean an increase in income for small producers or act in reducing the costs of the implementation and maintenance in agroforestry systems; operating as an agent of economic sustainability.

O Projeto Geoarqueologia da Amazônia (CNPq-UFOPA) tem realizado o estudo etnopedológico junto às comunidades quilombolas que habitam a margem direita do rio Trombetas na Floresta Nacional Saracá-Taquera, município de Oriximiná (PA). No âmbito deste projeto foram identificados até o momento doze sítios arqueológicos pré-coloniais, tendo ocorrido a escavação do sítio Faissal, comunidade Juquirizinho, na qual foi obtida grande quantidade de material cerâmico. A região do Trombetas/Nhamundá vem sendo alvo de interesse e pesquisas arqueológicas desde o século XIX até a atualidade devido à ocorrência de ídolos de pedra, muiraquitãs, sítios extensos com terra preta e uma cerâmica indígena antiga ricamente decorada. Os estudos que se debruçam sobre esse material apontam a incidência de ao menos três tipos cerâmicos com cronologias distintas. O Konduri, mais superficial e recente (entre X e XV d.C.), é associado à Tradição Inciso-Ponteada, sendo marcado pelo uso de grande quantidade de cauixi como antiplástico, profusão de modelados, incisões e ponteados como motivos decorativos, bases trípodes com suportes cônicos e adornos biomorfos. O Pocó, de estratigrafia mais profunda e antiga (I a.C. e IV d.C), vem sendo relacionado a complexos cerâmicos da Amazônia Central (Manacapuru e Açutuba), caracterizando-se pela utilização da policromia, modelado e incisões como decoração, cauixi e cariapé como antiplástico predominante e vasos carenados. Há ainda a ocorrência de outro tipo associado à decoração incisa “espinha de peixe”, mas sem grande aprofundamento em sua análise na literatura disponível, sendo caracterizado pela utilização de mineral (quartzo) como antiplástico, fragmentos pouco espessos, maciços e por vezes decorados com motivos incisos e adornos circulares. Esse trabalho tem o objetivo de apresentar os dados preliminares obtidos a partir da análise do material cerâmico do sítio Faissal, que apresenta predomínio da cerâmica Konduri e intrusão significativa da chamada cerâmica “espinha de peixe” no mesmo horizonte estratigráfico, sendo pontual a incidência do material Pocó. Tal correlação entre tipos cerâmicos distintos, antes de dizerem respeito a limites espaciais e temporais de grupos culturais diferenciados, tem o potencial de discutir a interação entre indústrias cerâmicas ao menos em parte contemporâneas. Afinal, trata-se de numa região conhecida pelo contato e inter-relação entre culturas arqueológicas oriundas da Amazônia Central e Baixo Amazonas, bem como pelo registro etno-histórico e etnográfico da inserção das populações indígenas locais em extensas redes de trocas nas Guianas, onde a calha principal do Amazonas seria um dos polos de atração.

No. of bitstreams: 0 Previous issue date: 2019-06-01 Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) In the southern Brasília Orogen, slices of an intensively reworked Paleoproterozoic basement occur. These are partially covered by a Neoproterozoic sequence of high-metamorphic grade, corresponding to the Socorro–Guaxupé Nappe and intruded by several Neoproterozoic plutonic rocks. In this contribution, we present thermobarometric and geochronological data of the basement rocks in the Campinas city, southern part of the Brasilia Orogen. The occurrence of mafic granulites included as lenses in mylonitic gneisses is described for the first time in a quarry located in the southern part of Campinas. Petrographic studies revealed high temperature paragenesis composed of orthopyroxene, clinopyroxene, garnet, biotite, and plagioclase. We present thermobarometric results with conditions close to the metamorphic peak, at ca. 8.7–10 kbar and 820–890 °C, which characterize these rocks as medium-pressure mafic granulites. U–]Pb zircon ages of 2134 ± 6 Ma and 2156 ± 6 Ma were obtained for the host gneisses and the mafic granulite, respectively and interpreted as the timing of their igneous crystallization. Metamorphic zircon overgrowths in the mafic granulites show a concordia age of 608 ± 3 Ma. This age is coeval with one of the several episodes of melt crystallization reported in the southern Brasilia Orogen. The Paleoproterozoic ages of ca. 2.15 Ga suggest that the protoliths of the gneisses and granulites in the Campinas region are similar to the rocks of the Pouso Alegre Complex, which represents part of the lower São Francisco plate overthrusted by the Brasilia Orogen during the Neoproterozoic orogenic collage in southeastern Brazil.

The energy balance closure obtained through the eddy covariance method is a problem which persists, despite advances in the development and improvement of instruments and recent efforts in the description of corrections and in the characterization of measuring uncertainties. In most places the sum of sensible and latent heat fluxes (H and λE) is less than available energy, i.e. the difference between net radiation (Rn) and soil heat flux (G). This study analyzed the annual and seasonal behavior of the energy partitioning and energy balance closure in the Caatinga Biome, which is a seasonally dry tropical forest located in the semiarid lands of Brazil, using the eddy covariance method. Results showed high seasonal variability in the energy partitioning. During the dry season, approximately 70% of Rn was converted into H and less than 5% of it was converted into latent heat flux (λE). During the wet season, the Rn portion converted into H and λE was similar: ˜ 40%. In annual terms, the Rn portion converted into H and λE was of the order of 50% and 20% respectively. The degree of the energy balance closure varied depending on the method used. When the closure was calculated using orthogonal regressions, the slope varied from 0.87 to 0.90 in 2014 and from 0.92 to 1.00 in 2015. However, when the closure was calculated by the energy balance ratio method, values varied from 0.70 to 0.79 in 2014 and from 0.73 to 0.82 in 2015. The closure was better in 2015 if compared to 2014 possibly due to the more intense turbulence observed in 2015 because friction velocity was higher than in 2014. The better closure in 2015 may also be associated with large eddies, which were more frequent in 2014 as evidenced by the correction coefficients for vertical wind velocity and water vapor and vertical wind velocity and sonic temperature. The energy balance closure was also analyzed considering atmospheric instability conditions and the best results were found under very unstable conditions, while the least expressive results were found under stable conditions. Under these conditions negative values of the energy balance ratio were also observed during dry and transition seasons, indicating that fluxes were reversed during these periods.

A compreensão da dinâmica de transmissão da Covid-19 é fundamental para que ações sejam tomadas na contenção de outros surtos. Na região amazônica, o processo de interiorização reflete o padrão de ocupação do território. Este trabalho busca investigar o processo de interiorização da epidemia causada pelo vírus SARS-COV-2 na região amazônica tendo como unidade temporal as semanas epidemiológicas. É adotada uma abordagem multiescalar, que nos permite indicar quatro fases de interiorização, desde a chegada via aérea nas capitais da Região Norte, até os registros de casos em comunidades tradicionais na Região de Saúde do Baixo Amazonas. As fases propostas são discutidas em função da percepção de comunitários a respeito da pandemia e das ações de saúde realizadas pelo Estado. Os resultados mostram que é fundamental considerar as especificidades do ambiente amazônico na formulação de estratégias de saúde efetivas, o que não ocorreu no caso da referida pandemia. Comprendre la dynamique de transmission de la Covid-19 est fondamental pour que des actions de contention puissent être menées. Dans la région amazonienne, les modes d’occupation du territoire informent le processus d’intériorisation du virus. Cet article analyse le processus d’intériorisation de l’épidémie de SARS-COV-2 en Amazonie brésilienne, au cours des semaines épidémiologiques. Une approche interdisciplinaire et multiscalaire permet de mettre à jour quatre phases d’intériorisation, depuis l’arrivée du virus par voie aérienne dans les capitales de la région Nord, jusqu’aux premiers cas enregistrés à l’échelle micro-locale, dans les villages des communautés traditionnelles de la Région de Santé du Bas Amazone. Ces phases sont également présentées à partir du point de vue des villageois et de celui des actions de santé mises en œuvre par les autorités. Les résultats montrent qu’il aurait été fondamental de prendre en compte les spécificités de l’environnement amazonien lors de l’élaboration des politiques de santé, contrairement à ce qui a été fait lors de cette épidémie. Understanding the transmission dynamics of Covid-19 is essential for actions to be taken to contain other outbreaks. In the Amazon region, the interiorization process reflects the territorial occupation pattern. This work aims to investigate the process of interiorization of the epidemic caused by the SARS COV 2 virus in the Amazon region, using epidemiological weeks as the temporal unit. A multiscale approach is adopted, which allows us to indicate four phases of interiorization, from the arrival by air in the capitals of the northern region, to record of cases in traditional communities in the Lower Amazon Health Region. The proposed phases are discussed according to the perception of community leaders regarding the pandemic and health actions carried out by the State. The results show that it is essential to consider the specificities of the Amazon environment when formulating effective health strategies, which did not occur in the case of the referred pandemic.

O objetivo neste trabalho e apresentar uma aplicacao na geociencia da termografia infravermelho para diagnosticar padroes termico-hidricos em solos com culturas irrigadas por potes de argila no oeste do Para, Amazonia. As imagens termograficas foram obtidas na unidade de referencia tecnologica (URT), instalada pelo projeto IrrigaPote, na comunidade de Lavras, no Oeste do Para. Foram realizados imageamentos a campo e analisados os padroes termicos nos seguintes alvos: T1: Aceroleira ( Malpighia emarginata ) sombreando solo com serrapilheira; T2: Aceroleira ( Malpighia emarginata ) sombreando solo sem serrapilheira; T3: Solo com serrapilheira; T4: Solo sem serrapilheira; e T5: Quintal agroflorestal contendo arvore secular com serrapilheira no solo. Os dados foram estratificados em valores extremos, medios, amplitude termica e analisada a umidade do solo. O diagnostico termografico no infravermelho proximo e os termogramas foram tratados no programa Flir Tools (6.3v). Os alvos termicos foram selecionados aleatoriamente, contabilizando-se 10 pontos nos cinco (05) tratamentos, totalizando-se 50 amostras. Fez-se analise estatistica descritiva em nivel de 5% de significância. Verificou-se diferencas termicas significativas entre solo exposto (T4=61,0°C) e no solo com serrapilheira (T3=43,8°C). Tambem, no solo sombreado com aceroleira na URT a temperaturas (T1=33,6°C) e no solo sombreado sem serrapilheira fora da URT (T2=32,7°C), evidenciando os efeitos da umidade no solo em decorrencia da irrigacao com potes de argila. As menores temperaturas (T5=30,3°C) foram detectadas no solo sombreado com arvore secular e existencia de serrapilheira na area do produtor rural. A regulacao termica evidencia que a irrigacao com potes de argila no solo esta alinhada aos objetivos de Desenvolvimento Sustentavel (ODS), principalmente o ODS 2 com a oferta de alimentos o ano todo; os ODS 6, 9 e 12, pois o reuso de agua da chuva na agricultura garante a producao de forma responsavel) e, ODS 13 como estrategia de regulacao termica para mitigar os efeitos decorrente de mudancas climaticas. A termografia infravermelho possui alto potencial de aplicacao em diferentes linhas de pesquisa na geociencia.

Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science. Our core approach involves linking long-term grassroots initiatives with standardized protocols and data management to generate robust scaled-up results. By connecting tropical researchers and elevating their status, our Social Research Network model recognises the key role of the data originator in scientific discovery. Conceived in 1999 with RAINFOR (South America), our permanent plot networks have been adapted to Africa (AfriTRON) and Southeast Asia (T-FORCES) and widely emulated worldwide. Now these multiple initiatives are integrated via ForestPlots.net cyber-infrastructure, linking colleagues from 54 countries across 24 plot networks. Collectively these are transforming understanding of tropical forests and their biospheric role. Together we have discovered how, where and why forest carbon and biodiversity are responding to climate change, and how they feedback on it. This long-term pan-tropical collaboration has revealed a large long-term carbon sink and its trends, as well as making clear which drivers are most important, which forest processes are affected, where they are changing, what the lags are, and the likely future responses of tropical forests as the climate continues to change. By leveraging a remarkably old technology, plot networks are sparking a very modern revolution in tropical forest science. In the future, humanity can benefit greatly by nurturing the grassroots communities now collectively capable of generating unique, long-term understanding of Earth's most precious forests. Resumen: Los bosques tropicales son los ecosistemas más diversos y productivos del mundo y entender su funcionamiento es crítico para nuestro futuro colectivo. Sin embargo, hasta hace muy poco, los esfuerzos para medirlos y monitorearlos han estado muy desconectados. El trabajo en redes es esencial para descubrir las respuestas a preguntas que trascienden las fronteras y los plazos de las agencias de financiamiento. Aquí mostramos cómo una comunidad global está respondiendo a los desafíos de la investigación en ecosistemas tropicales a través de diversos equipos realizando mediciones árbol por árbol en miles de parcelas permanentes de largo plazo. Revisamos los descubrimientos más importantes de este trabajo y discutimos cómo este proceso está cambiando la ciencia relacionada a los bosques tropicales. El enfoque central de nuestro esfuerzo implica la conexión de iniciativas locales de largo plazo con protocolos estandarizados y manejo de datos para producir resultados que se puedan trasladar a múltiples escalas. Conectando investigadores tropicales, elevando su posición y estatus, nuestro modelo de Red Social de Investigación reconoce el rol fundamental que tienen, para el descubrimiento científico, quienes generan o producen los datos. Concebida en 1999 con RAINFOR (Suramérica), nuestras redes de parcelas permanentes han sido adaptadas en África (AfriTRON) y el sureste asiático (T-FORCES) y ampliamente replicadas en el mundo. Actualmente todas estas iniciativas están integradas a través de la ciber-infraestructura de ForestPlots.net, conectando colegas de 54 países en 24 redes diferentes de parcelas. Colectivamente, estas redes están transformando nuestro conocimiento sobre los bosques tropicales y el rol de éstos en la biósfera. Juntos hemos descubierto cómo, dónde y porqué el carbono y la biodiversidad de los bosques tropicales está respondiendo al cambio climático y cómo se retroalimentan. Esta colaboración pan-tropical de largo plazo ha expuesto un gran sumidero de carbono y sus tendencias, mostrando claramente cuáles son los factores más importantes, qué procesos se ven afectados, dónde ocurren los cambios, los tiempos de reacción y las probables respuestas futuras mientras el clima continúa cambiando. Apalancando lo que realmente es una tecnología antigua, las redes de parcelas están generando una verdadera y moderna revolución en la ciencia tropical. En el futuro, la humanidad puede beneficiarse enormemente si se nutren y cultivan comunidades de investigadores de base, actualmente con la capacidad de generar información única y de largo plazo para entender los que probablemente son los bosques más preciados de la tierra. Resumo: Florestas tropicais são os ecossistemas mais diversos e produtivos da Terra. Embora uma boa compreensão destas florestas seja crucial para o nosso futuro coletivo, até muito recentemente os esforços de medições e monitoramento foram amplamente desconexos. É essencial formarmos redes para obtermos respostas que transcendem fronteiras e horizontes de agências financiadoras. Neste estudo nós mostramos como uma comunidade global está respondendo aos desafios da pesquisa de ecossistemas tropicais, com equipes diversas medindo florestas, árvore por árvore, em milhares de parcelas monitoradas à longo prazo. Nós revisamos as maiores descobertas científicas deste trabalho, e mostramos também como este processo está mudando a ciência de florestas tropicais. Nossa abordagem principal envolve unir iniciativas de base a protocolos padronizados e gerenciamento de dados a fim de gerar resultados robustos em escalas ampliadas. Ao conectar pesquisadores tropicais e elevar seus status, nosso modelo de Rede de Pesquisa Social reconhece o papel-chave do produtor dos dados na descoberta científica. Concebida em 1999 com o RAINFOR (América do Sul), nossa rede de parcelas permanentes foi adaptada para África (AfriTRON) e Sudeste asiático (T-FORCES), e tem sido extensamente reproduzida em todo o mundo. Agora estas múltiplas iniciativas estão integradas através de uma infraestrutura cibernética do ForestPlots.net, conectando colegas de 54 países de 24 redes de parcelas. Estas iniciativas estão transformando coletivamente o entendimento das florestas tropicais e seus papéis na biosfera. Juntos nós descobrimos como, onde e por que o carbono e a biodiversidade da floresta estão respondendo às mudanças climáticas, e seus efeitos de retroalimentação. Esta duradoura colaboração pantropical revelou um grande sumidouro de carbono persistente e suas tendências, assim como tem evidenciado quais direcionadores são mais importantes, quais processos florestais são mais afetados, onde eles estão mudando, seus atrasos no tempo de resposta, e as prováveis respostas das florestas tropicais conforme o clima continua a mudar. Dessa forma, aproveitando uma notável tecnologia antiga, redes de parcelas acendem faíscas de uma moderna revolução na ciência das florestas tropicais. No futuro a humanidade pode se beneficiar incentivando estas comunidades basais que agora são coletivamente capazes de gerar conhecimentos únicos e duradouros sobre as florestas mais preciosas da Terra. Résume: Les forêts tropicales sont les écosystèmes les plus diversifiés et les plus productifs de la planète. Si une meilleure compréhension de ces forêts est essentielle pour notre avenir collectif, jusqu'à tout récemment, les efforts déployés pour les mesurer et les surveiller ont été largement déconnectés. La mise en réseau est essentielle pour découvrir les réponses à des questions qui dépassent les frontières et les horizons des organismes de financement. Nous montrons ici comment une communauté mondiale relève les défis de la recherche sur les écosystèmes tropicaux avec diverses équipes qui mesurent les forêts arbre après arbre dans de milliers de parcelles permanentes. Nous passons en revue les principales découvertes scientifiques de ces travaux et montrons comment ce processus modifie la science des forêts tropicales. Notre approche principale consiste à relier les initiatives de base à long terme à des protocoles standardisés et une gestion de données afin de générer des résultats solides à grande échelle. En reliant les chercheurs tropicaux et en élevant leur statut, notre modèle de réseau de recherche sociale reconnaît le rôle clé de l'auteur des données dans la découverte scientifique. Conçus en 1999 avec RAINFOR (Amérique du Sud), nos réseaux de parcelles permanentes ont été adaptés à l'Afrique (AfriTRON) et à l'Asie du Sud-Est (T-FORCES) et largement imités dans le monde entier. Ces multiples initiatives sont désormais intégrées via l'infrastructure ForestPlots.net, qui relie des collègues de 54 pays à travers 24 réseaux de parcelles. Ensemble, elles transforment la compréhension des forêts tropicales et de leur rôle biosphérique. Ensemble, nous avons découvert comment, où et pourquoi le carbone forestier et la biodiversité réagissent au changement climatique, et comment ils y réagissent. Cette collaboration pan-tropicale à long terme a révélé un important puits de carbone à long terme et ses tendances, tout en mettant en évidence les facteurs les plus importants, les processus forestiers qui sont affectés, les endroits où ils changent, les décalages et les réactions futures probables des forêts tropicales à mesure que le climat continue de changer. En tirant parti d'une technologie remarquablement ancienne, les réseaux de parcelles déclenchent une révolution très moderne dans la science des forêts tropicales. À l'avenir, l'humanité pourra grandement bénéficier du soutien des communautés de base qui sont maintenant collectivement capables de générer une compréhension unique et à long terme des forêts les plus précieuses de la Terre. Abstrak: Hutan tropika adalah di antara ekosistem yang paling produktif dan mempunyai kepelbagaian biodiversiti yang tinggi di seluruh dunia. Walaupun pemahaman mengenai hutan tropika amat penting untuk masa depan kita, usaha-usaha untuk mengkaji dan mengawas hutah-hutan tersebut baru sekarang menjadi lebih diperhubungkan. Perangkaian adalah sangat penting untuk mencari jawapan kepada soalan-soalan yang menjangkaui sempadan dan batasan agensi pendanaan. Di sini kami menunjukkan bagaimana sebuah komuniti global bertindak balas terhadap cabaran penyelidikan ekosistem tropika melalui penglibatan pelbagai kumpulan yang mengukur hutan secara pokok demi pokok dalam beribu-ribu plot jangka panjang. Kami meninjau semula penemuan saintifik utama daripada kerja ini dan menunjukkan bagaimana proses ini sedang mengubah bidang sains hutan tropika. Teras pendekatan kami memberi tumpuan terhadap penghubungan inisiatif akar umbi jangka panjang dengan protokol standar serta pengurusan data untuk mendapatkan hasil skala besar yang kukuh. Dengan menghubungkan penyelidik-penyelidik tropika dan meningkatkan status mereka, model Rangkaian Penyelidikan Sosial kami mengiktiraf kepentingan peranan pengasas data dalam penemuan saintifik. Bermula dengan pengasasan RAINFOR (Amerika Selatan) pada tahun 1999, rangkaian-rangkaian plot kekal kami kemudian disesuaikan untuk Afrika (AfriTRON) dan Asia Tenggara (T-FORCES) dan selanjutnya telah banyak dicontohi di seluruh dunia. Kini, inisiatif-inisiatif tersebut disepadukan melalui infrastruktur siber ForestPlots.net yang menghubungkan rakan sekerja dari 54 negara di 24 buah rangkaian plot. Secara kolektif, rangkaian ini sedang mengubah pemahaman tentang hutan tropika dan peranannya dalam biosfera. Kami telah bekerjasama untuk menemukan bagaimana, di mana dan mengapa karbon serta biodiversiti hutan bertindak balas terhadap perubahan iklim dan juga bagaimana mereka saling bermaklum balas. Kolaborasi pan-tropika jangka panjang ini telah mendedahkan sebuah sinki karbon jangka panjang serta arah alirannya dan juga menjelaskan pemandu-pemandu perubahan yang terpenting, di mana dan bagaimana proses hutan terjejas, masa susul yang ada dan kemungkinan tindakbalas hutan tropika pada perubahan iklim secara berterusan di masa depan. Dengan memanfaatkan pendekatan lama, rangkaian plot sedang menyalakan revolusi yang amat moden dalam sains hutan tropika. Pada masa akan datang, manusia sejagat akan banyak mendapat manfaat jika memupuk komuniti-komuniti akar umbi yang kini berkemampuan secara kolektif menghasilkan pemahaman unik dan jangka panjang mengenai hutan-hutan yang paling berharga di dunia.

O presente trabalho objetivou identificar e analisar a dinâmica estratosferica dos eventos de influencia do Buraco de Ozonio Antartico (BOA) ocorridos sobre o Sul do Brasil no ano de 2016. Para atingir esse objetivo, buscou-se dias de reducao no conteudo de ozonio estratosferico com base em dados medios diarios da Coluna Total de Ozonio (CTO) obtidos pelo espectrofotometro Brewer instalado no Observatorio Espacial do Sul (OES/INPE) (29.443752 oS, 53.823084 oO; 488,7 metros) e pelo instrumento de medicao de Ozonio ( Ozone Monitoring Instrument - OMI) a bordo do satelite Aura da NASA. Para esses dias foram realizadas analises da dinâmica da estratosfera atraves de campos isentropicos de Vorticidade Potencial (PV) nos niveis de 600 e 700 K de temperatura potencial, utilizando as medias diarias de PV obtidas a partir das reanalises ERA-Interim do ECMWF ( European Centre for Medium-range Weather Forecast ) a fim de verificar a origem das massas de ar pobres em ozonio, e desta forma, a confirmacao da origem dessas massas atraves das trajetorias retroativas obtidas com uso do modelo HYSPLIT ( HYbrid Single-Particle Lagrangian Integrated Trajectory) da NOAA (National Oceanic and Atmospheric Administration ). Alem disso, imagens do conteudo de ozonio do satelite OMI foram utilizadas como tecnica complementar para verificar a atuacao do BOA sobre o Sul do Brasil. Usando a metodologia apresentada identificou-se 6 eventos de influencia do Buraco de Ozonio Antartico sobre o Sul do Brasil no ano de 2016 com percentagem de reducao media de 11% da CTO em relacao as climatologias mensais, confirmados pela passagem de filamentos polares estratosfericos sobre a regiao do OES, observados nos campos isentropicos de VP nos niveis de 600 e 700 K de temperatura potencial assim como pelas trajetorias retroativas de origem polar obtidas no modelo HYSPLIT.

The savannah biome has edaphoclimatic conditions conducive to the occurrence of Arbuscular Mycorrhizal Fungi (AMF), which associated with plants, become biotechnological tools of underestimated potential. One of the reasons is the difficulty in producing and spreading infectious propagules in a significant amount to develop studies under controlled conditions. The objective of this work was to analyze the multiplication of spores from the AMF from the Savannah of Alter do Chão, Western Pará, and the aspects of symbiosis in Brachiaria decumbens Stapf. as a hostess. The experiment was conducted under controlled conditions at the Laboratory of Plant Physiology and Plant Growth at the Federal University of Western Pará from February to October 2019. Two types of soils (commercial substrate and dystrophic yellow latosol) were tested at different time periods (20, 36, 65 and 129 days). For this, composite samples containing spores of native AMF were collected in the study area, of which 100 g were homogenized to 850 g of the tested soils, separately, in 1 kg pots. The experiment was carried out under laboratory conditions and the design was completely randomized, in a 2 × 4 factorial scheme (multiplication time × soil types) with four replications. The result of the spore density of the native FMA and the percentage of infection were submitted to Analysis of Variance and the means were compared by the Scott Knott test with p, El bioma de sabana tiene condiciones edafoclimático que conducen a aparición de Hongos Micorrízicos Arbusculares (HMA), que asociados con plantas, se convierten en herramientas biotecnológicas de potencial subestimado. Una razón es la dificultad de producir y difundir propágulos infecciosos en una cantidad significativa para desarrollar estudios en condiciones controladas. El objetivo de este estudio fue analizar la multiplicación de esporas de los HMA de la sabana de Alter do Chão, región occidental del Estado de Pará, y los aspectos de la simbiosis en Brachiaria decumbens Stapf. como hospedera. El experimento se llevó a cabo en condiciones controladas en el Laboratorio de Fisiología Vegetal y Crecimiento Vegetal de la Universidad Federal del Oeste de Pará de febrero a octubre de 2019. Se probaron dos tipos de suelos (sustrato comercial y latosol amarillo distrófico) en diferentes períodos de tiempo (20, 36, 65 y 129 días). Para esto, se recolectaron muestras compuestas que contenían esporas de HMA nativa en el área de estudio, de las cuales 100 g se homogeneizaron a 850 g de los suelos analizados, por separado, en florero de planta de 1 kg. El experimento se realizó en condiciones de laboratorio y el diseño fue completamente al azar, en un esquema factorial 2 × 4 (tiempo de multiplicación × tipos de suelo) con cuatro repeticiones. El resultado de la densidad de esporas de las FMA nativas y el porcentaje de infección se sometieron a Análisis de Varianza y las medias se compararon mediante la prueba de Scott Knott con p, O bioma de savana possui condições edafoclimáticas propícias a ocorrência dos Fungos Micorrízicos Arbusculares (FMA), que associados às plantas, tornam-se ferramentas biotecnológicas de potencial subestimado. Objetivou-se com este estudo analisar a multiplicação dos esporos dos FMA oriundos da Savana de Alter do Chão, Oeste do Pará, e a simbiose em Brachiaria decumbens Stapf. como hospedeira. O experimento foi conduzido em condições controladas no Laboratório de Fisiologia Vegetal e Crescimento de Plantas da Universidade Federal do Oeste do Pará, campus Santarém, no período de fevereiro a outubro de 2019. Foram testados dois tipos de solos (substrato comercial e latossolo amarelo distrófico) em diferentes períodos de tempos (20, 36, 65 e 129 dias). Para isso, amostras compostas contendo esporos dos FMA nativos foram coletadas na área de estudo, das quais 100 g foram homogeneizados a 850 g dos solos testados, separadamente, em vasos de 1 kg de capacidade. O experimento foi realizado em condições de laboratório e o delineamento foi inteiramente casualizado, em esquema fatorial 2×4 (tempo de multiplicação × tipos de solo) com quatro repetições. O resultado da densidade de esporos dos FMA nativos e o percentual de infecção foram submetidos à Análise de Variância e as médias foram comparadas pelo teste Scott Knott com p

National audience; The present study aims to analyze the stratospheric dynamics of the events of influence of the Antarctic Ozone Hole (BOA) that occurred over the South of Brazil in 2016. To reach this goal, days of reduction were used in the stratospheric ozone content based on Total Ozone Column (CTO) daily average data obtained from the Brewer spectrophotometer installed at the Southern Space Observatory (OES/INPE) (29.443752 ºS, 53.823084 ºW; 488.7 meters) and by the Ozone measuring instrument (Ozone Monitoring Instrument - OMI) onboard the NASA Aura satellite. For those days, stratosphere dynamics analyses were carried out through isentropic fields of Potential Vorticity (PV) at 600 and 700 K (Kelvin) levels of potential temperature, using the daily PV averages obtained from ERAInterim reanalysis of ECMWF (European Center for Medium-range Weather Forecast) to verify the origin of the ozone-poor air masses. Thus, the confirmation of the origin of these masses through the retroactive trajectories obtained using the HYSPLIT model (HYbrid Single-Particle Lagrangian Integrated Trajectory) of NOAA (National Oceanic and Atmospheric Administration). In addition, images of the ozone content of the OMI satellite were used as a complementary technique to verify the performance of BOA over SouthernBrazil. Then, 6 events of influence of the Antarctic Ozone Hole were identified over the South of Brazil in 2016, with an average reduction percentage of 11% of the CTO to monthly climatologies, confirmed by the passage of stratospheric polar filaments over the OES region, observed in the VP isentropic fields at the 600 and 700 K potential temperature levels as well as by the retroactive trajectories of polar origin obtained in the HYSPLIT model.; O presente trabalho objetivou identificar e analisar a dinâmica estratosférica dos eventos de influência do Buraco de Ozônio Antártico (BOA) ocorridos sobre o Sul do Brasil no ano de 2016. Para atingir esse objetivo, buscou-se dias de redução no conteúdo de ozônio estratosférico com base em dados médios diários da Coluna Total de Ozônio (CTO) obtidos pelo espectrofotômetro Brewer instalado no Observatório Espacial do Sul (OES/INPE) (29.443752 ºS, 53.823084 ºO; 488,7 metros) e pelo instrumento de medição de Ozônio (Ozone Monitoring Instrument - OMI) a bordo do satélite Aura da NASA. Para esses dias foram realizadas análises da dinâmica da estratosfera através de campos isentrópicos de Vorticidade Potencial (PV) nos níveis de 600 e 700 K de temperatura potencial, utilizando as médias diárias de PV obtidas a partir das reanálises ERA-Interim do ECMWF (European Centre for Medium-range Weather Forecast) a fim de verificar a origem das massas de ar pobres em ozônio, e desta forma, a confirmação da origem dessas massas através das trajetórias retroativas obtidas com uso do modelo HYSPLIT (HYbrid Single-Particle Lagrangian Integrated Trajectory) da NOAA (National Oceanic and Atmospheric Administration). Além disso, imagens do conteúdo de ozônio do satélite OMI foram utilizadas como técnica complementar para verificar a atuação do BOA sobre o Sul do Brasil. Usando a metodologia apresentada identificou-se 6 eventos de influência do Buraco de Ozônio Antártico sobre o Sul do Brasil no ano de 2016 com percentagem de redução média de 11% da CTO em relação as climatologias mensais, confirmados pela passagem de filamentos polares estratosféricos sobre a região do OES, observados nos campos isentrópicos de VP nos níveis de 600 e 700 K de temperatura potencial assim como pelas trajetórias retroativas de origem polar obtidas no modelo HYSPLIT.

International audience; Toxicity of methylmercury (MeHg) to wildlife and humans results from its binding to cysteine residues of proteins, forming MeHg-cysteinate (MeHgCys) complexes that hinder biological functions. MeHgCys complexes can be detoxified in vivo, yet how this occurs is unknown. We report that MeHgCys complexes are transformed into selenocysteinate [Hg(Sec)4] complexes in multiple animals from two phyla (a waterbird, freshwater fish, and earthworms) sampled in different geographical areas and contaminated by different Hg sources. In addition, high energy-resolution X-ray absorption spectroscopy (HR-XANES) and chromatography-inductively coupled plasma mass spectrometry of the waterbird liver support the binding of Hg(Sec)4 to selenoprotein P and biomineralization of Hg(Sec)4 to chemically inert nanoparticulate mercury selenide (HgSe). The results provide a foundation for understanding mercury detoxification in higher organisms and suggest that the identified MeHgCys to Hg(Sec)4 demethylation pathway is common in nature.

En Amazonie, l’une des régions du Brésil les plus touchées par l’épidémie de COVID-19, les statistiques épidémiologiques publiées par les autorités brossent un tableau de la crise sanitaire qui interroge, car il ne considère pas ou trop partiellement le sort des populations issues des minorités ethniques et culturelles qui habitent la région. Au cours de la première vague épidémique (de février à juillet 2020), une équipe de 11 chercheurs a recensé et analysé la mobilisation des populations autochtones et quilombolas, et leur appropriation de l’outil statistique, pour apparaître dans les chiffres officiels. En réaction à ces mobilisations, les bulletins épidémiologiques publiés par les États et les communes amazoniennes ont fortement évolué d’un mois sur l’autre, faisant apparaître différentes lectures de la crise sanitaire, ancrées dans les imaginaires et les enjeux de pouvoir des régions amazoniennes. L’analyse met en évidence ce combat, discret mais essentiel, des minorités ethniques du pays, pour que soient actées, par les chiffres et dans les discours, les conséquences de l’épidémie sur leurs populations., In Amazonas, one of the regions of Brazil most affected by the COVID-19 epidemic, epidemiological statistics published by authorities paint a picture of the health crisis that must be called into question, as it does not or only partially considers the situation of ethnic and cultural minorities living in the region. During the first wave of the pandemic (from February to July 2020), a team of 11 researchers documented and analyzed the protests of Indigenous populations and quilombolas and their appropriation of statistical tools, to appear in the official statistics. As a response to these protests, epidemiological updates published by the states and Amazonian municipalities evolved greatly from one month to the next, reflecting the different interpretations of the health crisis anchored in the imaginations and power interests of Amazonian regions. The analysis underscores the subtle but essential fight of the country’s ethnic minorities to ensure that the consequences of the epidemic on their population are recorded both in the official numbers and in policies.

International audience; Beyond reducing deforestation, the control of forest degradation, the promotion of forest restoration, and the improvement of agricultural practices in the Brazilian Amazon are becoming increasingly important for sustainable development. To enable farmers and authorities to organize their landscapes and optimize both agricultural practices and the provision of ecosystem services, mapping land suitability is essential, but it is lacking in the region. In this paper, we present a method for mapping land suitability at a fine scale (30-m pixels), adapted to the needs of farmers and municipalities, to not only optimize agricultural production but also the ecosystem services provided by forests. We used topographic data from the Brazilian municipality of Paragominas to produce four maps, one each of soil texture, slope, floodplains, and hydrography, that we then combined into a single land suitability map. This map has been incorporated into a spatial database, which also contains information on land use, remoteness, and land tenure. We performed spatial analyses to measure the process of land use change, and to define indicators that enable local stakeholders to organize landscape restoration. We highlight an organic link between agricultural intensification and forest restoration, and provide a spatial tool for landscape design, assessment, and monitoring.

No. of bitstreams: 0 Previous issue date: 2021-01-01 The Tapajós river is among the largest rivers in the world and has been credited as the main affluent of the lower Amazon River. Geomorphological studies in the Tapajós commonly deal with evolutionary, hydrological, and sedimentological issues. Recently, important advances have been made in understanding the morphology and dynamics in the Tapajós, especially in the confluence zone near Santarém, eastern Amazonian Brazil. However, the lack of an independent channel classification system makes it difficult to integrate data obtained from different sources. This work presents a classification system for the lower Tapajós based on morphometric variables extracted from transversal profiles coupled with radar and optical remote sensing data. We used discriminant analysis of principal components for the first time in fluvial geomorphology to provide a clustering-based geomorphological classification, which is statistically supported. We propose a segmentation of the channel into three distinct sections referred to as narrower channel reach, higher ria reach, and lower ria reach. The results showed that the channel has a distinct morphological pattern in each of these reaches, which can also be observed by the variation along the longitudinal profile. Our findings showed that the most variable hydrological and sedimentological patterns are found in the lower ria reach, while the higher ria reach comprises a canyon-shaped, more stable part of the channel. We discuss the implications of this pattern on the ria’s evolution. The method developed here could be applied to other areas of the Amazon basin, where the lack of data and logistical difficulties carrying out fieldwork are common obstacles to large-scale investigations. The identified reaches are indended to be considered in the sample design of future works and in the formulation of water resources management strategies.

A new species of Hyphessobrycon belonging to the Hyphessobrycon heterorhabdus species-group from the lower rio Tapajós, state of Pará, Brazil, is described. The new species is allocated into the Hyphessobrycon heterorhabdus species-group due to its color pattern, composed by an anteriorly well-defined, horizontally elongated humeral blotch that becomes diffuse and blurred posteriorly, where it overlaps with a conspicuous midlateral dark stripe that becomes blurred towards the caudal peduncle and the presence, in living specimens, of a tricolored longitudinal pattern composed by a dorsal red or reddish longitudinal stripe, a middle iridescent, golden or silvery longitudinal stripe, and a more ventrally-lying longitudinal dark pattern composed by the humeral blotch and dark midlateral stripe. It can be distinguished from all other species of the group by possessing humeral blotch with a straight or slightly rounded ventral profile, lacking a ventral expansion present in all other species of the group. The new species is also distinguished from Hyphessobrycon heterorhabdus by a 9.6% genetic distance in the cytochrome c oxidase I gene. The little morphological distinction of the new species when compared with its most similar congener, H. heterorhabdus, indicates that the new species is one of the first truly cryptic fish species described from the Amazon basin. RESUMO Uma nova espécie de Hyphessobrycon pertencente ao grupo Hyphessobrycon heterorhabdus é descrita da região do baixo rio Tapajós, estado do Pará, Brasil. A nova espécie é incluída no grupo Hyphessobrycon heterorhabdus devido ao seu padrão de coloração, composto por uma mancha umeral alongada, anteriormente bem definida, que se torna difusa e borrada posteriormente, onde se sobrepõe a uma conspícua faixa escura médio-lateral que se torna borrada próxima ao pedúnculo caudal, e pela presença, em exemplares vivos, de um padrão longitudinal tricolor, composto por uma faixa longitudinal vermelha ou avermelhada dorsal, uma faixa média iridescente dourada ou prateada e, mais ventralmente, o padrão longitudinal escuro composto pela faixa escura médio-lateral e mancha umeral. A espécie pode ser distinguida das outras espécies pertencentes ao grupo por possuir uma mancha umeral com região ventral retilínea ou levemente arredondada, sem uma expansão ventral presente nas demais espécies do grupo. A espécie também se diferencia de Hyphessobrycon heterorhabdus por uma distância genética de 9,6% no gene citocromo c oxidase I. A sutil diferença morfológica da nova espécie quando comparada ao seu congênere mais similar, H. heterorhabdus, indica que a nova espécie é uma das primeiras espécies de peixes verdadeiramente crípticas descritas da Bacia Amazônica.

This study aimed to analyze the economic viability of the implantation of a family aquaponic system module in western Pará. To estimate the cost of production, we used the operating cost structure proposed by the Institute of Agricultural Economics - IEA. For investment evaluation, three scenarios were considered (lettuce commercialization price R$ 2.00, 2.50 and 3.00), and the financial analyzes prepared through calculations of investment required for the installation of aquaponics through revenue and expenditure entries. Among the implementation costs, 59,44% is linked to the assembly of the aquaponic system and 40,60% to the greenhouse construction. Labor and electricity were the items that most compensated the cost of production, with 32.58 and 30.62%, respectively. In addition, for all scenarios, the viability indices indicate that the activity is attractive for investments, with Internal Rate of Return between 11,06 and 53,55%, Net Present Value ranging from R$ 213,06 and 16.788,39 and Return on Investment from 2 to 8 years. Given this, the system analyzed proved to be economically viable in all three proposed scenarios, however, we suggest the development of public policies that seek to reduce electricity costs for the small producer, intending to stimulate the development of this activity, increasing the income and food production in a more sustainably way in the state of Pará.KEYWORDS: Lettuce, Production cost, Investment, Economic Indicators, Colossoma macropomum., El objetivo de este estudio fue analizar la viabilidad económica de la implementación de un módulo de sistema acuapónico de naturaleza familiar en el oeste de Pará. Para estimar el costo de producción, se utilizó la estructura de costos operacionales propuesta por el Instituto de Econômia Agrícola - IEA. Para la evaluación de investimentos, se consideraron tres escenarios (precio de comercialización de la lechuga R$ 2,00, 2,50 y 3,00), y los análisis financieros elaboradas mediante cálculos de los volúmenes de investimentos necesarios para la instalación de acuaponía a través de ingresos de lucros y gastos. Entre los costes de implementación, el 59,44% está vinculado al montaje del sistema acuapónico y el 40,60% destinado a la construcción del invernadero de producción vegetal. La mano de obra y la electricidad fueron los artículos que pagaron más el costo de producción, con un 32,58 y un 30,62%, respectivamente. Además, para todos los escenarios los índices de viabilidad indican que la actividad es atractiva para investimentos, con Tasa Interna de Retorno entre 11,06 y 53,55%, Valor Presente Neto que oscila entre R$ 213,06 y 16.788,39 y Tiempo de Retorno del Investimento de 2 a 8 años. Por lo tanto, el sistema analizado demostró ser factible desde el punto de vista económico en los tres escenarios propuestos, sin embargo, se sugiere la formulación de políticas públicas que busquen reducir los valores de las tarifas con electricidad para el pequeño productor, con la intención de estimular el desarrollo de esta actividad, promover una mayor generación de rentas y aumentar la producción de alimentos de manera más sostenible en el estado de Pará.PALABRAS CLAVES: Lechuga, Costo de producción, Inversión, Indicadores económicos, Colossoma macropomum., Objetivou-se analisar a viabilidade econômica da implantação de um módulo de sistema aquapônico de cunho familiar no oeste paraense.

The objective of this work was to verify the influence of the Macrobrachium amazonicum shrimps food restriction time in transport simulation during the 10hours period. 600 specimens (0.22 ± 0.08 g) in storage density of 50 shrimps L-1 and two treatments: 12h (T12) and 24h (T24) previous food fasting, with 6 repetitions each. The experimental units were transparent plastic bags with 1 L of water and 2 of oxygen in the ratio of 1: 3 volume with water and 2:3 with oxygen. Water collection from each experimental unit was performed at 0, 5 and 10 hours to measure pH, electric conductivity, dissolved oxygen, temperature and total ammonia. At the end of the experimental period, the live and dead animals were counted. Surviving shrimps were subjected to a post-transport stress test by abruptly changing the water pH from 6.7 to 5.0 for 4 hours. Shrimps survival in transport simulation was similar between T12 (86 ± 2.53%) and T24 (86 ± 4.84%) (p>0.05) and did not differ statistically in post-transport stress (93.22 ± 8.83 and 89.49 ± 7.41%, T12 and T24, respectively). Therefore, to make transport of M. amazonicum for 10 hours the producer can choose the previous fasting 12 or 24 hours., El objetivo de este estudio fue verificar la influencia del tiempo de ayuno de la comida de camarones Macrobrachium amazonicum en una simulación del transporte durante el período de 10 horas. Se utilizaron 600 camarones (0,22 ± 0,08 g) en una densidad de almacenamiento de 50 camarones L-1 y dos tratamientos: ayuno previo de 12 h (T12) y 24 h (T24), con 6 repeticiones cada uno. Los equipos de ensayo eran bolsas de plástico transparentes con la adición de 1 L de agua y 2 de oxígeno gaseoso en una proporción de 1:3 el volumen de agua y de 2:3 y el oxígeno. La recolección de agua de cada unidad experimental se realizó a las 0, 5 y 10 horas para medir el pH, la conductividad electrica, el oxígeno disuelto, la temperatura y el amoniaco total. Al final del período de experimentación, se contaron los animales vivos y muertos. Los camarones sobrevivientes fueron sometidos a una prueba de estrés post-transporte, a través de un cambio repentino en el pH del agua de 6.7 a 5.0, durante 4 horas. La supervivencia de las gambas en la simulación de transporte fue similar entre T12 (86 ± 2,53%) y T24 (86 ± 4,84%) (p>0,05), y no difirió estadísticamente en el estrés postransporte (93,22 ± 8,83 y 89,49 ± 7,41%, T12 y T24, respectivamente). Por lo tanto, para transportar M. amazonicum durante 10 horas, el productor puede optar por un ayuno de comida previo de 12 o 24 horas., Este trabalho teve como objetivo verificar a influência do tempo de jejum alimentar do camarão Macrobrachium amazonicum em uma simulação de transporte durante o período de 10 horas. Utilizou-se 600 camarões (0,22 ± 0,08 g) em densidade de estocagem de 50 camarões L-1 e dois tratamentos: jejum alimentar prévio de 12 h (T12) e de 24h (T24), com 6 repetições cada. As unidades experimentais foram sacos plásticos transparentes com adição de 1 L de água e 2 de oxigênio na proporção de 1:3 do volume com água e 2:3 com oxigênio. A coleta de água de cada unidade experimental, foi realizada nos tempos 0, 5 e 10 horas para aferição do pH, condutividade elétrica, oxigênio dissolvido, temperatura e amônia total. Ao final do período experimental, realizou-se a contagem dos animais vivos e mortos. Os camarões sobreviventes foram submetidos a um teste de estresse pós–transporte, através da alteração brusca de pH da água de 6,7 para 5,0, durante 4 horas. A sobrevivência dos camarões na simulação de transporte foi semelhante entre o T12 (86 ± 2,53%) e o T24 (86 ± 4,84%) (p>0,05), assim como não diferiu estatisticamente no estresse pós-transporte (93,22 ± 8,83 e 89,49 ± 7,41% nos T12 e T24, respectivamente). Por tanto, para realizar o transporte do M. amazonicum por 10 horas o produtor pode optar pelo jejum alimentar prévio de 12 ou 24 horas.

Os indicadores são substâncias indigestíveis, geralmente de fácil determinação, muito utilizados para estimar a produção fecal em animais através de amostras fecais, dispensando coleta total de fezes. Os indicadores são bastante estudados em ovinos e bovinos, porém estudos em bubalinos são escassos, dessa forma objetivou-se avaliar a eficácia dos indicadores LIPE®, Óxido de Cromo III (Cr2O3) e Óxido de Titânio (TiO2) para estimar a produção fecal em búfalos. Utilizou-se 18 búfalos (Bubalus bubalis) machos, Murrah, com peso vivo médio de 150 kg. Uma vez ao dia a mensuração da excreção fecal foi realizada através da coleta total de fezes e estimada por indicadores externos LIPE®, Cr2O3 e TiO2. As estimativas de produção fecal com indicadores Cr2O3 e o LIPE® não diferiram da produção fecal determinada pela coleta total, porém não houve correlação com a coleta total. A estimativa de produção fecal realizado pelo TiO2 superestimou a produção total de fezes, porem houve correlação positiva com a coleta total de fezes, podendo ser corrigido a seguinte equação: Excreção fecal (Kg.d-1) = 0.17*Excreção fecal estimada pelo TiO2 (Kg.d-1) + 2.0671., Indicators are extensively studied in sheep and cattle, but studies in buffalo are scarce, so they aim to evaluate the measures of the LIPE®, Chromium Oxide III (Cr2O3) and Titanium Oxide (TiO2) indicators to estimate fecal production in buffaloes. We used 18 male buffalo (Bubalus bubalis), Murrah, with an average live weight of 150 kg. Once a day, the measurement of fecal excretion was performed through the total collection of doses and estimates by external indicators LIPE®, Cr2O3 and TiO2. As the fecal production with Cr2O3 and LIPE® indicators did not differ from the fecal production specified by the total collection, however there was no correlation with the total collection. An estimate of fecal production performed by TiO2 overestimated the total production of feces, as there is a positive correlation with the total collection of feces, which can be corrected by the following equation: Fecal excretion (Kg.d-1) = 0.17 * Estimated fecal excretion by TiO2 (Kg.d-1) + 2.0671., Los indicadores son sustancias no digeribles, generalmente fáciles de determinar, ampliamente utilizadas para estimar la producción fecal en animales a través de muestras fecales, eliminando la colección total de heces. Los indicadores se estudian ampliamente en ovejas y vacas, pero los estudios en búfalos son escasos, por lo que el objetivo fue evaluar la efectividad de los indicadores LIPE®, óxido de cromo III (Cr2O3) y óxido de titanio (TiO2) para estimar la producción fecal en búfalos. Se utilizaron dieciocho búfalos machos (Bubalus bubalis), Murrah, con un peso vivo promedio de 150 kg. Una vez al día, la medición de la excreción fecal se realizó a través de la recolección total de heces y se estimó mediante indicadores externos LIPE®, Cr2O3 y TiO2. Las estimaciones de producción fecal con indicadores Cr2O3 y LIPE® no difirieron de la producción fecal determinada por la colección total, pero no hubo correlación con la colección total. La estimación de la producción fecal realizada por TiO2 sobreestimó la producción total de heces, pero hubo una correlación positiva con la colección total de heces, y se puede corregir la siguiente ecuación: Excreción fecal (Kg.d-1) = 0.17 * Excreción fecal estimada por TiO2 (Kg.d-1) + 2.0671.

Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty?three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty?one species are included in some conservation?threatened categories of global and/or national endangered species lists. Other 30 species are included in the near?threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.

International audience; Polypodiaceae is one of the most diverse and abundant families of ferns in tropical and subtropical forests. Despite multiple studies investigating its phylogeny and taxonomy, several generic boundaries within the family still need clarification. One of the most problematic circumscriptions is that of Polypodium L., and one species that still contributes to this uncertainty is Polypodium chrysolepis Hook. The main goal of this study was to use molecular and morphological data to clarify the relationships of P. chrysolepis inside the polygrammoid clade. Sequences from three plastid regions (cpDNA – rbcL, rps4 and rps4–trnS IGS) from fifty species belonging to thirty-two genera of Polypodiaceae were analyzed using maximum likelihood and Bayesian inference. Polypodium chrysolepis constitutes an isolated lineage among the neotropical polygrammoid ferns, close to Serpocaulon and the grammitids, and is recognized here in a new genus. It can be distinguished by its entire leaves with free veins and peltate, pedicellate, lanceolate paraphyses. A new combination, Adetogramma chrysolepis, is proposed and a new taxonomic treatment is presented; its conservation status was assessed using IUCN Red List Categories and Criteria.

The Amazon Basin is an unquestionable biodiversity hotspot, containing the highest freshwater biodiversity on earth and facing off a recent increase in anthropogenic threats. The current knowledge on the spatial distribution of the freshwater fish species is greatly deficient in this basin, preventing a comprehensive understanding of this hyper-diverse ecosystem as a whole. Filling this gap was the priority of a transnational collaborative project, i.e. the AmazonFish project - https://www.amazon-fish.com/. Relying on the outputs of this project, we provide the most complete fish species distribution records covering the whole Amazon drainage. The database, including 2,406 validated freshwater native fish species, 232,936 georeferenced records, results from an extensive survey of species distribution including 590 different sources (e.g. published articles, grey literature, online biodiversity databases and scientific collections from museums and universities worldwide) and field expeditions conducted during the project. This database, delivered at both georeferenced localities (21,500 localities) and sub-drainages grains (144 units), represents a highly valuable source of information for further studies on freshwater fish biodiversity, biogeography and conservation., Measurement(s)Diversity • Fish • spatial patternTechnology Type(s)digital curationFactor Type(s)geographic locationSample Characteristic - OrganismfishSample Characteristic - Environmentdrainage basinSample Characteristic - LocationAmazon Basin Machine-accessible metadata file describing the reported data: 10.6084/m9.figshare.11920800

Made available in DSpace on 2021-06-25T10:18:20Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01 The western state of Pará region has attracted increasing investments due to its strategic position within a model of exportation in consolidation in Brazil, of commodity outflow via the Amazon waterway. This interest is accompanied by conflicts associated with the implementation of works, especially infrastructure and logistics and changes in land use, such as land conversion processes. Within this scenario, it is essential to have subsidies for an adequate environmental planning of both the works and the economic activities that have been proposed and implemented at a regional level. This work proposes, through geomorphological compartmentation on a suitable scale, to contribute to the environmental planning process of this region, focusing on the Maicá floodplain, situated in the Santarém municipality, pointing out the potentialities and vulnerabilities found in each compartment. Optical remote sensing and radar data acquired on the basis of the local hydrological regime, associated with official data (nautical and topographic charts) and field observations are used. The description of the identified compartments also provides elements for the discussion on the origin and evolution of the geomorphological forms and processes in the Amazon floodplain and “terra firme”, as well as providing the bases for more detailed studies that can investigate the relationships between the compartments found.

The objective of this work was to evaluate the environmental impacts of the community forest management in the Tapajós National Forest executed by the Tapajós Mixed Cooperative (COOMFLONA), analyzing aspects intrinsic to the physical aspects intrinsicto the physical, biological and socioeconomic environment, especially local direct and indirect effects. The identification and characterization of the impacts with qualitative data based on the magnitude and importance of the impacts on the environment and on a Leopold matrix was performed. In the evaluation, the actions that generated alterations in the habits of the traditional population, soil compaction, habitat reduction, increased hunting activity, damage to remaining trees, opening of branches, clearings and storage yards, which generated the local extinction and extinction of the fauna temporarily, increase of the erosive processes and decrease of the vegetal genetic base. Although forest management adopted by community members impacts less than conventional logging, logging still affects forest, but does not break its resilience and, in a sense, promotes environmental conservation.KEYWORDS: Production system, Conservation, Amazon., Este trabajo tuvo el objetivo de evaluar los impactos ambientales resultantes del manejo forestal comunitario en el Bosque Nacional del Tapajós ejecutado por la Cooperativa Mixta de la FLONA del Tapajós (COOMFLONA) analizando aspectos intrínsecos al medio físico, biológico y socioeconómico, especialmente los efectos locales directos e indirectos.

The Antarctic ozone hole (AOH) directly influences the Antarctic region, where its levels can reach values below 220 DU. The temporary depletion of ozone in Antarctica generally occurs between the beginning and middle of August, during the austral spring, and extends to November, when a temporary reduction in ozone content is observed in a large region over the Antarctic continent. However, masses of ozone-depleted air can break away from the ozone hole and reach mid-latitude regions in a phenomenon known as the secondary effect of the Antarctic ozone hole. The objective of this paper is to show how atmospheric dynamics behave during the occurrence of this type of event, especially in mid-latitude regions, such as southern Brazil, over a 12-year observation period. For the analysis and identification of the events of influence of the AOH on the southern region of Brazil, data from the total ozone column were used from ground-based and satellite experiments, the Brewer Spectrophotometer (MkIII no. 167), and the Ozone Monitoring Instrument (OMI) on the Aura satellite. For the analysis of the stratospheric and tropospheric fields, the ECMWF reanalysis products were used. Thus, 37 events of influence of the AOH that reached the southern region of Brazil were identified for the study period (2006–2017), where the events showed that in approximately 70 % of the cases they occurred after the passage of frontal systems and/or atmospheric blocks over southern Brazil. In addition, the statistical analysis showed a strong influence of the jet stream on mid-latitude regions during the events. Among the 37 identified events, 92 % occurred in the presence of the subtropical and/or polar jet stream over the region of study, possibly explaining the exchange of air masses of ozone deficient in the upper troposphere–lower stratosphere (UT–LS) region.

Para dar conta desse objetivo propusemos uma pesquisa orientada pelo método do materialismo histórico dialético. Em consonância com o método assumido, realizamos pesquisa bibliográfica, documental e empírica. Dessa forma, a pesquisa contemplou informações qualitativas, promovidas por entrevistas com questões abertas, fontes documentais e dados quantitativos secundários obtidos por meio da pesquisa em bases de dados. A seleção dos participantes da pesquisa foi feita por meio de amostragem não probabilística snowball sampling (bola de neve), por meio de contato via email com seis pessoas reconhecidas como referências nacionais em justiça restaurativa. Estas primeiras pessoas deram início ao processo da bola de neve, indicando outros contatos de pessoas que desenvolviam práticas de justiça juvenil restaurativa há, pelo menos, dois anos, e que realizavam intervenções que eles consideravam como representativas no atendimento ao adolescente autor de ato infracional, de qualquer região do país. Após esta etapa, encaminhamos questionário online para os 23 participantes que haviam sido sugeridos, a fim de caracterizar a experiência de justiça juvenil restaurativa e convidá-los a participar da pesquisa. Obtivemos retorno de 10 questionários. Considerando os critérios de seleção da pesquisa e a voluntariedade das pessoas em participar, selecionamos 4 locais para a realização da pesquisa: Ponta Grossa-PR, Caxias do Sul-RS, BelémPA e Santarém-PA, contemplando experiências nas regiões sul e norte do país. Deslocamo-nos até as cidades para a realização da pesquisa e realizamos 39 entrevistas semiestruturadas, contemplando como participantes os adolescentes autores de ato infracional, seus familiares, facilitadores e membros da rede de proteção social. A partir da triangulação de dados, organizamos as seguintes categorias de análise: 1) o ato infracional como expressão da vulnerabilidade social; 2) a intersetorialidade na justiça juvenil restaurativa; e, 3) a justiça restaurativa na qualificação do atendimento socioeducativo. Tais categorias foram correlacionadas com dados quantitativos de fontes secundárias de três principais bases de dados: IBGE, Atlas de Desenvolvimento Humano do Brasil e Relatório de Informações Sociais do Cadastro Único. Concluímos que a justiça restaurativa na justiça juvenil tem contribuído para humanizar o atendimento ao adolescente autor de ato infracional e, também, atribuir sentido à medida socioeducativa. Ainda, a inclusão da rede de proteção social na justiça juvenil restaurativa tem se destacado como um encontro intersetorial, potencializando o trabalho em rede e fortalecendo os vínculos entre adolescentes, familiares e serviços de proteção social, o que contribui para a aquisição de bens sociais. Problematizamos, entretanto, o protagonismo da justiça na articulação de políticas públicas, em razão do sucateamento dos serviços públicos, o que, por sua vez, pode acarretar a sobrecarga e/ou a culpabilização dos profissionais pela ausência do investimento necessário ao funcionamento dos serviços. The purpose of this research was to analyze how the constitution of juvenile restorative justice in Brazil has been articulated to the social protection network in the perspective of the guarantee of rights, and what has been its impact on the acquisition of social goods to the adolescents engaged in practices of offensive conduct and their families. To achieve this objective we proposed a study driven by a method of dialectical historical materialism. According to the assumed method, we performed bibliographical, documentary and empirical research. In this way, the research included qualitative information, promoted by interviews with open questions, documentary sources and secondary quantitative data obtained by searching databases. The selection of the participants of the research was made through non-probabilistic snowball sampling, through e-mail contact with six people recognized as national references in restorative justice. These first people started the snowball process, indicating other contacts of people who had been practicing restorative juvenile justice for at least two years, and who had performed interventions that they considered as representative in the care of the adolescent engaged in practices of offensive conduct, from any region of the country. After this step, we sent an online questionnaire to the 23 participants that had been suggested, in order to characterize the restorative juvenile justice experience and invite them to participate in the research. We received ten questionnaires. Considering the research selection criteria and the people's willingness to participate in the research, we selected 4 cities for the research: Ponta Grossa-PR, Caxias do Sul-RS, BelémPA and Santarém-PA, with experiences from southern and north regions of the country. We went to the cities to carry out the research and carried out 39 semistructured interviews with the adolescents who engaged in practices of offensive conduct, their families, facilitators and members of the social protection network. From the triangulation of data, we organized the following categories of analysis: 1) the infraction as an expression of social vulnerability; 2) intersectoriality in juvenile restorative justice; and, 3) restorative justice in the qualification of socio-educational care. These categories were correlated with quantitative data from secondary sources from three main databases: IBGE, Human Development Atlas of Brazil and Social Data Report of the Single Cadastre. We conclude that restorative justice in juvenile justice has contributed to humanize the care of the adolescents engaged in practices of offensive conduct and also to give meaning to the socio-educational measure. Furthermore, the inclusion of the social protection network in juvenile restorative justice has been highlighted as an intersectorial meeting, inhancing networking and strengthening ties between teenagers, families and social protection services, which contributes to the acquisition of social goods. However, we problematize the role of justice in the articulation of public policies, due to the scrapping of public services, which, in turn, can lead to overloading and/or blame by professionals for the lack of the necessary investment for the functioning of services.

International audience; The temperature response of photosynthesis is one of the key factors determining predicted responses to warming in global vegetation models (GVMs). The response may vary geographically, owing to genetic adaptation to climate, and temporally, as a result of acclimation to changes in ambient temperature. Our goal was to develop a robust quantitative global model representing acclimation and adaptation of photosynthetic temperature responses. We quantified and modelled key mechanisms responsible for photosynthetic temperature acclimation and adaptation using a global dataset of photosynthetic CO2 response curves, including data from 141 C3 species from tropical rainforest to Arctic tundra. We separated temperature acclimation and adaptation processes by considering seasonal and common‐garden datasets, respectively. The observed global variation in the temperature optimum of photosynthesis was primarily explained by biochemical limitations to photosynthesis, rather than stomatal conductance or respiration. We found acclimation to growth temperature to be a stronger driver of this variation than adaptation to temperature at climate of origin. We developed a summary model to represent photosynthetic temperature responses and showed that it predicted the observed global variation in optimal temperatures with high accuracy. This novel algorithm should enable improved prediction of the function of global ecosystems in a warming climate.
