Amazonia ,bureaucracy ,Venezuela ,mobility - Abstract
This article explores an apprenticeship in bureaucracy that the Venezuelan Sanema have experienced through their participation in the projects of the late Hugo Chavez’s Bolivarian Revolution. The analysis focuses on the maneuverability that paperwork engenders, and thus contributes to an understanding of mobility and corporeal experiences of state apparatus in contemporary Amazonia. New patterns of movement—travel to and from cities, daily errands, and maneuvering within social spheres—must be understood with reference to the state and its bureaucratic pervasiveness, but also as congruous with customary practices of “journeying for knowledge,” which forge an intimate link between physical and social mobility. The new maneuverability that is both prompted and necessitated by the current political setting is equally as important as literacy in navigating bureaucratic structures and accessing state resources.

Notions of animals as social subjects held by Amazonian Indians have played a central role in anthropology's ontological turn. Written as a reply to two critical responses to an earlier paper on human-animal relations, this essay explores the complex and often contradictory nature of ideas about animals and attitudes toward them held by both Amerindians and Euro-Americans. It suggests that, alongside mythology and shamanism, a further source of the Amerindians' ideas about animals as social subjects lies in their everyday interactions with animals, something they share in common with Welsh sheep farmers. This fits uneasily with Philippe Descola's contrast between animism and naturalism. The essay concludes by querying radical contrasts between "us" and "them." Such contrasts may have their heuristic, comparative, and rhetorical uses but tend to oversimplify complex ethnographic reality. [ABSTRACT FROM AUTHOR]

The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from different Amazon regions to compile the most extensive data set of inventories of mammal, bird, and reptile species ever assembled for the area. The complete data set comprises 154,123 records of 317 species (185 birds, 119 mammals, and 13 reptiles) gathered from surveys from the Amazonian portion of eight countries (Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela). The most frequently recorded species per taxa were: mammals: Cuniculus paca (11,907 records); birds: Pauxi tuberosa (3713 records); and reptiles: Tupinambis teguixin (716 records). The information detailed in this data paper opens up opportunities for new ecological studies at different spatial and temporal scales, allowing for a more accurate evaluation of the effects of habitat loss, fragmentation, climate change, and other human‐mediated defaunation processes in one of the most important and threatened tropical environments in the world. The data set is not copyright restricted; please cite this data paper when using its data in publications and we also request that researchers and educators inform us of how they are using these data.

The creative and ever-expanding appropriations of bureaucracy and documents on the part of Amazonian peoples today transcend simple dichotomies between orality and literacy, state and non-state power, and domination and resistance. The papers collected here highlight the specific forms taken by such engagements and the ways in which they assume a key role in local political processes, offering new perspectives on issues ranging from the everyday workings of the state to local theories of language and materiality. In this introductory essay we draw particular attention to the importance of documents as mediators which facilitate new forms of communication; to the prevalence of bureaucratic magic and ritual; and to the ways in which regional bureaucratic and documentary processes are closely linked to both wealth and violence.

Isotopes in tropical trees rings can improve our understanding of tree responses to climate. We assessed how climate and growing conditions affect tree-ring oxygen and carbon isotopes (δ18OTR and δ13CTR) in four Amazon trees. We analysed within-ring isotope variation for two terra firme (non-flooded) and two floodplain trees growing at sites with varying seasonality. We find distinct intra-annual patterns of δ18OTR and δ13CTR driven mostly by seasonal variation in weather and source water δ18O. Seasonal variation in isotopes was lowest for the tree growing under the wettest conditions. Tree ring cellulose isotope models based on existing theory reproduced well observed within-ring variation with possible contributions of both stomatal and mesophyll conductance to variation in δ13CTR. Climate analysis reveal that terra firme δ18OTR signals were related to basin-wide precipitation, indicating a source water δ18O influence, while floodplain trees recorded leaf enrichment effects related to local climate. Thus, intrinsically different processes (source water vs leaf enrichment) affect δ18OTR in the two different species analysed. These differences are likely a result of both species-specific traits and of the contrasting growing conditions in the floodplains and terra firme environments. Simultaneous analysis of δ13CTR and δ18OTR supports this interpretation as it shows strongly similar intra-annual patterns for both isotopes in the floodplain trees arising from a common control by leaf stomatal conductance, while terra firme trees showed less covariation between the two isotopes. Our results are interesting from a plant physiological perspective and have implications for climate reconstructions as trees record intrinsically different processes. © The Author(s) 2019.

MINERAL oils ,POETICS ,VENEZUELANS ,LATIN American literature ,METAPHOR - Abstract
In the beginning of the twentieth century, after its rapid insertion into the vortex of oil and mineral extraction, Venezuela was forced to re-think its relationship with nature. This process of rethink, characterised by an eagerness for modernisation, resulted in a series of discourses focused on Venezuela's Amazonia as a repository of possibilities. This paper analyses how these possibilities were channelled through the metaphor of el secreto de la tierra, tracing an early reading of the ideological configuration of Venezuela and its Amazonia as a land of inexhaustible material and poetic richness. This metaphor was voiced by a set of socio-ecological discourses written about the Venezuelan Amazon, including the essay on Venezuelan geography and culture by Enrique Bernardo Núñez Una ojeada al mapa de Venezuela (1939). The paper focuses on the representation of this region as a set of discursive constructions entangled with the naturalisation of the modernising ideal that has fuelled the imaginaries of material growth and rentier capitalism in Venezuela. The concluding remarks will point to how such a reading can help us to understand a discursive and poetic radicalisation embedded in conflicting approaches to the nature-culture confluence in the Venezuelan Amazon.

Bacuri (Platonia insignis Mart) is a species from the Clusiaceae genus. Its fruit pulp is commonly used in South America in several food products, such as beverages, ice cream and candies. Only the pulp of the fruit is used, and the peels and seeds are considered waste from these industries. As a trioxygenated xanthone source, this species is of high interest for bioproduct development. This work evaluated the mesocarp and epicarp of bacuri fruits through different extraction methods and experimental conditions (pH, temperature and solvent) in order to determine the most effective method for converting this agro-industrial waste in a value-added bioproduct. Open-column procedures and HPLC and NMR experiments were performed to evaluate the chemical composition of the extracts, along with total phenols, total flavonoids and antioxidant activities (sequestration of the DPPH and ABTS radicals). A factorial design and response surface methodology were used. The best extraction conditions of substances with antioxidant properties were maceration at 50 °C with 100% ethanol as solvent for mesocarp extracts, and acidic sonication in 100% ethanol for epicarp extracts, with an excellent phenolic profile and antioxidant capacities. The main compounds isolated were the prenylated benzophenones garcinielliptone FC (epicarp) and 30-epi-cambogin (mesocarp). This is the first study analysing the performance of extraction methods within bacuri agro-industrial waste. Results demonstrated that shells and seeds of bacuri can be used as phenolic-rich bioproducts obtained by a simple extraction method, increasing the value chain of this fruit.

Nonstructural carbon (NSC) reserves act as buffers to sustain tree activity during periods when carbon (C) assimilation does not meet C demand, but little is known about their age and accessibility; we designed a controlled girdling experiment in the Amazon to study tree survival on NSC reserves. We used bomb-radiocarbon (14C) to monitor the time elapsed between C fixation and release (‘age’ of substrates). We simultaneously monitored how the mobilization of reserve C affected δ13CO2. Six ungirdled control trees relied almost exclusively on recent assimilates throughout the 17 months of measurement. The Δ14C of CO2 emitted from the six girdled stems increased significantly over time after girdling, indicating substantial remobilization of storage NSC fixed up to 13–14 yr previously. This remobilization was not accompanied by a consistent change in observed δ13CO2. These trees have access to storage pools integrating C accumulated over more than a decade. Remobilization follows a very clear reverse chronological mobilization with younger reserve pools being mobilized first. The lack of a shift in the δ13CO2 might indicate a constant contribution of starch hydrolysis to the soluble sugar pool even outside pronounced stress periods (regular mixing). © 2018 The Authors.

Offset schemes help avoid or revert habitat loss through protection of existing habitat (avoided deforestation), through the restoration of degraded areas (natural regrowth), or both. The spatial scale of an offset scheme may influence which of these 2 outcomes is favored and is an important aspect of the scheme's design. However, how spatial scale influences the trade‐offs between the preservation of existing habitat and restoration of degraded areas is poorly understood. We used the largest forest offset scheme in the world, which is part of the Brazilian Forest Code, to explore how implementation at different spatial scales may affect the outcome in terms of the area of avoided deforestation and area of regrowth. We employed a numerical simulation of trade between buyers (i.e., those who need to offset past deforestation) and sellers (i.e., landowners with exceeding native vegetation) in the Brazilian Amazon to estimate potential avoided deforestation and regrowth at different spatial scales of implementation. Allowing offsets over large spatial scales led to an area of avoided deforestation 12 times greater than regrowth, whereas restricting offsets to small spatial scales led to an area of regrowth twice as large as avoided deforestation. The greatest total area (avoided deforestation and regrowth combined) was conserved when the spatial scale of the scheme was small, especially in locations that were highly deforested. To maximize conservation gains from avoided deforestation and regrowth, the design of the Brazilian forest‐offset scheme should focus on restricting the spatial scale in which offsets occur. Such a strategy could help ensure conservation benefits are localized and promote the recovery of degraded areas in the most threatened forest landscapes., Article impact statement: Conservation offset schemes may yield greater additionality through avoided deforestation and restoration if implemented in smaller areas.

This paper investigates the effects of advancing deforestation in the southwestern Amazon on local hydroclimate. For this purpose, a high-resolution mesoscale model, coupled with a land surface model and a hydrologic routing model, is integrated for five years in two experiments, one control without changes in land use and another changing land use annually. During the rainy season, simulated higher precipitation volumes are reduced with the expansion of pasture lands. In the dry periods, mainly in August, there is an increase in precipitation over some deforested areas, which can be associated with mesoscale circulations induced by the heterogeneous surface. In general, land-use changes reduce evapotranspiration and the net radiation at the surface and increase the sensible heat flux during the dry season. In the rainy period, there is an increase in evapotranspiration with the intensification of deforestation, which modifies the other components of energy balance. Results suggest that the impact of LUCC on the local climate is more affected by conditions that generate precipitation extremes (El Niño/La Niña events) than by the abrupt increase in the annual deforestation rate. Land-use changes reduce the streamflow in all sub-basins of Ji-Parana during the dry season. In the rainy season, LUCC increases the streamflow during periods with normal precipitation conditions and La Niña in almost all sub-basins, except in the sub-basin with more than 20% deforestation.

Smoke stimulates seed germination of a range of species from ecosystems that may or may not be fire prone. We evaluated the effects of smoke-water on germination of ten tree species of economic value in the Amazon region. Two materials were burnt to produce smoke-water: germination paper and the wood of Cecropia palmata Willd. Seven dilutions of the solutions were tested. Seeds of nine forest trees were germinated under controlled laboratory conditions (25 °C. ± 2 °C) in the laboratory. Bertholletia excelsa Humb. & Bonpl., was tested in the nursery (approximately 25-36. °C) because of its large seeds. Irrespective of the material burned, smoke-water significantly increased seed germination of three species: Cordia goeldiana Hub., Ochroma pyramidale (Cav. ex Lam.) Urb. and Jacaranda copaia (Aubl.) D. Don. and there was a significant inhibitory effect on Swietenia macrophylla King. Germination was accelerated by smoke in J. copaia, B. excelsa and Bellucia grossularioides (L.) Triana. The most pronounced effect was observed in B. excelsa, as the mean germination time of 108. d (control) was reduced to 76. d with smoke-water made from germination paper (dilution of 1:25) and to 61. d with the one from Cecropia wood (dilution of 1:250). For five of the ten species studied, smoke-water either increased or accelerated seed germination, irrespective of the materials used for its production. Seeds with low vigour and prolonged germination time seemed to be more receptive to smoke. © 2013 South African Association of Botanists.

The proximate compositions, mineral contents, antioxidant capacity and bioactive compounds of 7 native Amazon fruits were chemically evaluated. The majority of the fruits showed high moisture contents (> 63.02%), and ash, total crude protein and total carbohydrate contents in the ranges of 0.22–2.07%, 0.17–2.44% and 7.17–41.71%, respectively. High levels of total lipids were found in uxi (23.25%) and monguba (18.67%). A wide range of mineral contents was detected and the highest levels were found in the samples of monguba seeds (Ca, Cu, Mg, and Zn), uxi pulp (Fe, and Mn) and pajurá pulp (Na). All the fruits showed antioxidant capacity, but the pajurá revealed the highest potential, statistically similar to that of acerola (p < 0.05). The highest vitamin C contents were found in bacuri and cupuaçu and the highest phenolic compound contents in monguba and pajurá fruits, but flavonoids were only detected in pajurá. A statistical correlation between the Na content and antioxidant capacity was also observed. Based on the results obtained, the fruits analyzed are suitable for use in the human diet, in the food and cosmetics industries as well as in pharmaceutical compositions. Resumo A composição bromatológica, o conteúdo mineral e a capacidade antioxidante de 7 frutos nativos da Amazônia foram avaliados. Os frutos mostraram, em sua maioria, alto conteúdo de umidade (> 63,02%) e teores de cinzas, proteína bruta total e carboidratos totais na faixa de 0,22-2,07%, 0,17-2,44% e 7,17-41,71%, respectivamente. Os maiores teores em lipídios foram obtidos nos frutos de uxi (23,25%) e monguba (18,67%). Uma ampla variedade de minerais foi detectada, sendo as maiores concentrações obtidas nas amostras de sementes de monguba (Ca, Cu, Mg e Zn), polpas de uxi (Fe e Mn) e pajurá (Na). Todos os frutos mostraram atividade antioxidante, em que a polpa de pajurá revelou o maior potencial, semelhante estatisticamente à acerola (p < 0,05). Maiores teores em vitamina C foram obtidos nos frutos de bacuri e cupuaçu, fenólicos totais na monguba e pajurá, enquanto flavonóides foram determinados somente nos frutos de pajurá. Uma correlação positiva entre o teor de Na e a capacidade antioxidante também foi observada. Baseado nos resultados obtidos, os frutos analisados são adequados para uso na dieta humana, nas indústrias de alimentos e cosméticos, bem como em composições farmacêuticas.

This study evaluated the post-acidification, stability of anthocyanins and antioxidant activity in açai yogurts and fermented milks for 28 days of cold storage. For the determination of post-acidification and stability of the functional properties of açai yogurt (IA) and fermented milks (LFA), products stored at 4°C were evaluated on day 0 and every 7 days for pH, titratable acidity in lactic acid, instrumental color, anthocyanins and antioxidant activity by the DPPH free radical method. Acidification of both food matrixes was more evident between days 0 and 7 of evaluation. IA presented reduction in parameter L *, while chromaticity a * and b * of IA and LFA increased as the Açai pulp content increased; however, considering the evaluation period, it was found increase in L * and b * relating to anthocyanin degradation. Anthocyanins, as well as the antioxidant activity of IA and LFA, showed an increase in their values as the pulp content increased, but their concentrations reduced at the end of the storage period. IA and LFA can be considered excellent sources of antioxidants, being alternative to individuals not used to the consumption of fruits and vegetables. RESUMO Neste trabalho foi avaliada a pós-acidificação, a estabilidade das antocianinas e da atividade antioxidante em iogurtes e leites fermentados de açaí durante 28 dias de armazenamento refrigerado. Para determinação da pós-acidificação, assim como da estabilidade das propriedades funcionais dos iogurtes (IA) e leites fermentados (LFA) de açaí, os produtos armazenados a 4 ºC, foram avaliados no dia 0 e a cada 7 dias, quanto ao pH, acidez titulável em ácido lático, cor instrumental, antocianinas e atividade antioxidante pelo método do radical livre DPPH. A acidificação de ambas as matrizes alimentares foram mais evidentes entre os dias 0 e 7 de avaliação. Os IA apesentaram redução no parâmetro L*, enquanto que as cromaticidade a* e b* dos IA e LFA aumentaram seus valores, à medida que o teor de polpa de açaí foi aumentado, entretanto considerando o período de avaliação, verificou-se aumento de L* e b* relacionando-se as degradações nas antocianinas. As antocianinas, assim como a atividade antioxidante dos IA e LFA mostraram aumento em seus valores conforme os teores de polpa foram aumentados, porém reduziram suas concentrações ao fim do período de armazenamento. Os IA e LFA, podem ser considerados excelentes fontes de substâncias antioxidantes, sendo alternativa a indivíduos não habituados ao consumo de frutas e legumes.

Despite extensive research on unsaturated soil behavior in recent decades, the field of transportation engineering still lacks technically and economically feasible methods for identifying expansive soils along roads, particularly in regions with limited laboratory infrastructure that are distant from developed areas in Brazil. This situation is particularly evident in the state of Acre, located in the southwest of the Brazilian Amazon, where the subgrade predominantly consists of fine, plastic soils and faces challenges of limited availability of crushed stone and high precipitation levels. The volumetric variation of expansive soils in Acre has resulted in significant financial losses and has affected the lives of the local population. This paper proposes a simplified method for the preliminary identification of expansive clays, which is based on geotechnical characterization tests that can be performed at local laboratories. The proposed method utilizes the correlation between the plasticity index (PI) and silt/clay content to determine ranges that express the highest probability of occurrence of soils susceptible to shrink-swell behavior. This method was developed by correlating geotechnical parameters of 321 samples from EMBRAPA's SiSolos database with a geotechnical database of 100 local samples. [ABSTRACT FROM AUTHOR]

In chronicles written during the XVI and XVII centuries the Antis (a general name used as a collective term to describe a great variety of ethnic groups living in the eastern and Amazonian corner of the empire), were portrayed as rebels, uncivilised, sometimes as barbarians and cannibals. Guaman Poma de Ayala reinforces this discourse both in his text and drawings where we can see images of the Antis as Indians living in caves and read about their practicing of anthropophagy. In this short paper I shall focus on the work of Guaman Poma de Ayala and his perception of the Antis. Nas crônicas escritas durante os séculos XVI e XVII no Peru, os Antis (um nome geral usado como termo coletivo para descrever uma grande variedade de grupos étnicos vivendo na parte Amazônica do império), foram representados como rebeldes, não civilizados, bárbaros e até mesmo canibais. Guaman Poma de Ayala reforça esse discurso ambos em seu texto e desenhos onde é possível ver imagens dos Antis vivendo em cavernas e ler sobre suas práticas de antropofagia. Neste pequeno artigo, será estudado o manuscrito de Guaman Poma de Ayala e sua percepcão dos Antis.

- Abstract
Archaeometry had a slow start in the study of Amazonian and Caribbean ceramics, practiced almost exclusively by professionals outside of the archaeology discipline, primarily geologists, physicists and chemists, but is now slowly gaining track among archaeologists. In this paper, we summarize the archaeometric research done in the last thirty years in ceramics from the Amazon and Caribbean regions, emphasizing its main questions, aims and future developments for archaeometry in Latin America. Archaeometric studies are a growing field of research and improve understanding of past networks, technological knowledge and cultural traditions. [ABSTRACT FROM AUTHOR]

This paper presents a description of the segmental and prosodic phonology of Muniche, a critically endangered Peruvian Amazonian isolate. Using data from team-based fieldwork with a group of rememberers of Muniche, this paper describes the segmental inventory, syllable structure, and stress system of the language, plus a number of prosodically motivated epenthetic processes. A historical overview of the language and its contact with neighboring Kawapanan languages is also presented. Finally, the results of this study are compared with Gibson (1996), the sole previous study of Muniche phonology. [ABSTRACT FROM AUTHOR]

Uncertainty remains over local‐scale responses of ecotonal Amazonian forests to middle Holocene drying due to the scarcity, and coarse spatial resolution, of lacustrine pollen records. This paper examines the palaeoecological potential of soil phytoliths, stable carbon isotopes and charcoal for capturing local‐scale ecotonal responses of different types of Bolivian Amazonian forest to middle Holocene climate change. Soil pits 1 m deep were dug at ecotones between rainforest, dry forest, Chaco woodland and savannah, and sampled at 5–10 cm resolution. Both phytolith and stable carbon isotope records indicate stability of dry forest–savannah ecotones over the last ca. 6000 years, despite middle Holocene drought, revealing the dominance of edaphic factors over climate in controlling this type of ecotone. In contrast, δ13C data reveal that rainforest–savannah ecotones were more responsive to climate change, with rainforest likely replaced by drought‐tolerant dry forest or savannah vegetation during the mid‐Holocene, consistent with regional‐scale lacustrine pollen records. However, such shifts are not apparent in most of our phytolith records due to insufficient taxonomic resolution in differentiating rainforest from dry forest. Charcoal data show that ecotonal dry forests experienced greater fire activity than rainforests and that recent high fire activity at all forest sites is unprecedented since at least the middle Holocene.

Drawing on original ethnobotanical and anthropological research among Indigenous peoples across the Amazon, we examine synergies and dissonances between Indigenous and Western scientific knowledge about the environment, resource use, and sustainability. By focusing on the sensory dimension of Indigenous engagements with the environment—an approach we have described as "sensory ecology" and explored through the method of "phytoethnography"—we promote a symmetrical dialogue between Indigenous and scientific understandings around such phenomena as animal–plant mutualisms, phytochemical toxicity, sustainable forest management in "multinatural" landscapes, and the emergence of new diseases like the novel coronavirus SARS‐CoV‐2 (COVID‐19). Drawing examples from our own and other published works, we explore the possibilities and limitations of a "parallax view" attempting to hold Indigenous and scientific knowledge in focus simultaneously. As the concept of "bioeconomy" emerges as a key alternative for sustainable development of the Amazon, we encourage a critical and urgent engagement between dominant Western conceptions and Indigenous Amazonian knowledge, practices, and cultural values. Cognitive science, which has long contributed to studies of Indigenous categorization and conceptualization of the natural world, continues to play an important role in building bridges of mutual communication and respect between Indigenous and scientific approaches to sustainability and biodiversity conservation. This paper explores the possibilities and limitations of a "parallax view" attempting to hold Indigenous and scientific knowledge in focus simultaneously in order to promote interdisciplinary and intercultural dialogue, sustainability, and biodiversity conservation.

Phytolith analysis is a well-established archaeobotanical tool, having provided important insights into pre-Columbian crop cultivation and domestication across Amazonia through the Holocene. Yet, its use as a palaeoecological tool is in its infancy in Amazonia and its effectiveness for reconstructing pre-Columbian land-use beyond archaeological sites (i.e., 'off-site') has so far received little critical attention. This paper examines both new and previously published soil phytolith data from SW Amazonia to assess the robustness of this proxy for reconstructing pre-Columbian land-use. We conducted the study via off-site soil pits radiating 7.5 km beyond a geoglyph in Acre state, Brazil, and 50 km beyond a ring-ditch in northern Bolivia, spanning the expected gradients in historical land-use intensity. We found that the spatio-temporal patterns in palm phytolith data across our soil-pit transects support the hypothesis that pre-Columbian peoples enriched their forests with palms over several millennia, although phytoliths are limited in their ability to capture small-scale crop cultivation and deforestation. Despite these drawbacks, we conclude that off-site soil phytolith analysis can provide novel insights into pre-Columbian land use, provided it is effectively integrated with other land-use (e.g., charcoal) and archaeological data.

The tropical rainforest of Amazonia is one of the most species-rich ecosystems on earth, with an estimated 16000 tree species. Due to this high diversity, botanical identification of trees in the Amazon is difficult, even to genus, often requiring the assistance of parataxonomists or taxonomic specialists. Advances in informatics tools offer a promising opportunity to develop user-friendly electronic keys to improve Amazonian tree identification. Here, we introduce an original multi-access electronic key for the identification of 389 tree genera occurring in French Guiana terra-firme forests, based on a set of 79 morphological characters related to vegetative, floral and fruit characters. Its purpose is to help Amazonian tree identification and to support the dissemination of botanical knowledge to non-specialists, including forest workers, students and researchers from other scientific disciplines. The electronic key is accessible with the free access software Xper², and the database is publicly available on figshare: https://figshare.com/articles/GuiaTreeKey/2682550 (doi: 10.6084/m9.figshare.2682550).

Background Diversity and distribution of Neotropical aquatic insects is still poorly known, with many species to be recorded and many others to be described, due to the small number of taxonomists and sparse faunistic studies. This knowledge is especially poor in the Caatinga Domain in Northeastern Brazil, even though, this region may have played an important historical role in the spatial evolution of faunas of forested areas in northern South America.New information Aquatic insect checklists of 96 species from Parque Nacional de Ubajara (Ceará State, Brazil) and 112 species from Parque Nacional de Sete Cidades (Piauí State, Brazil) are presented, representing the following taxa: Elmidae, Epimetopidae, Hydrophilidae, and Torridincolidae (Coleoptera), Hemerodromiinae (Diptera: Empididae), Ephemeroptera, Gerromorpha and Nepomorpha (Hemiptera), Odonata, Plecoptera, and Trichoptera. Because of the scarce number of biological inventories in Northeastern Brazil, several new distributional records (of species, genera, and families) for Brazil, Northeastern Brazil, and Ceará and Piauí states are provided. In addition, several undescribed species were detected, being 26 from Ubajara and 20 from Sete Cidades. Results represent a significant increase to the known fauna of these states, ranging from 13%-70% increase for Ceará and 41% to 91% increase for Piauí. Although both parks are relatively close to each other and within the Caatinga domain, their aquatic fauna display a very high complementarity (89% species), possibly due to structural differences of water bodies sampled in each park. Rarefaction curves based on quantitative light trap samples suggest a much higher expected species richness of aquatic insects at Sete Cidades than at Ubajara National Park. Discussion on biogeographical affinities of this sample of the Caatinga fauna is provided. © Takiya D et al.

The Venezuelan economic crisis, combined with the creation of the Orinoco Mining Arc (OMA), has pushed thousands of people to work in wildcat mines in the Venezuelan Guayana. Even though attempts have been made to control illegal mining in the past, the absence of planning and lack of concrete economic alternatives have made these efforts unsuccessful. Spatial planning could play an important role in developing a rural regional strategy aimed at making other livelihood options available. This is a challenging endeavour, however, because the Venezuelan Guayana is the largest and least populated region of the country, with most of its surface covered by fragile forests rich in ecological and cultural diversity. Moreover, data to inform decision-making are unavailable or severely limited. This paper presents an approach that attempts to overcome those obstacles and seeks to identify which are the peripheral remote areas where resource extraction and its negative externalities are most present, conflicting with the preservation of the forest, its biodiversity and the livelihoods of Indigenous populations. The conclusions presented here might assist spatial planners and policymakers who seek to explore territorial approaches for rural development and inform decision-making in peripheral regions where data are scarce.

This volume argues that looking at gardens through the lens of art and aesthetics generates new insights into the role that gardens have for those who make and depend on them. Drawing on some of the debates around the anthropology of art, we suggest that aesthetics provides a rich analytical perspective on the importance of gardens to many wider aspects of social life. We argue for the critical conceptual significance of gardens in Melanesia, and in Amazonia. In doing so, we foreground the importance of diversity in gardening: in plants and knowledge practices, and in the recognition of non-human beings and their collaboration with gardeners. This is, in part, a factor of the satisfactions that people find in growing beautiful and diverse gardens that link to myth, to history and to place. This introduction sets out these arguments and also provides a summary of each of the papers presented in the volume. [ABSTRACT FROM AUTHOR]

Understanding the resilience of moist tropical forests to treefall disturbance events is important for understanding the mechanisms that underlie species coexistence and for predicting the future composition of these ecosystems. Here, we test whether variation in the functional composition of Amazonian forests determines their resilience to disturbance. We studied the legacy of natural treefall disturbance events in four forests across Amazonia that differ substantially in functional composition. We compared the composition and diversity of all free-standing woody stems 2-10 cm diameter in previously disturbed and undisturbed 20 × 20 m subplots within 55, one-hectare, long-term forest inventory plots. Overall, stem number increased following disturbance, and species and functional composition shifted to favour light-wooded, small-seeded taxa. Alpha-diversity increased, but beta-diversity was unaffected by disturbance, in all four forests. Changes in response to disturbance in both functional composition and alpha-diversity were, however, small (2 - 4% depending on the parameter) and similar among forests. Synthesis. This study demonstrates that variation in the functional composition of Amazonian forests does not lead to large differences in the response of these forests to treefall disturbances, and overall, these events have a minor role in maintaining the diversity of these ecosystems. Understanding how the diversity of tropical forests responds to treefall disturbance events is important for understanding mechanisms of species coexistence and for predicting the future composition of these ecosystems. Previous studies have focussed on single sites and have contradictory results. By studying four sites in Amazonia, we demonstrate that these events have a consistent, but minor, role in maintaining the diversity of these ecosystems. © 2016 British Ecological Society.

Hunting in tropical forests is typically most intense near human settlements, and this creates gradients of decreasing animal densities toward those settlements. Within the context of this spatial pattern, we evaluated the status of game in the hunting grounds of an indigenous community in eastern Ecuador. We constructed a spatially explicit model of hunter-prey interactions that mimicked the hunting in the village and included realistic animal-dispersal rules. We compared predictions from the model with distributions of animal harvest rates and catch per unit effort of 12 game species. Six species were overharvested in part or all of the area, and two other species were probably being overharvested, although high dispersal rates complicated the interpretation. We then compared our method with methods that have been used previously. We argue that because our method provides information about the spatial extent of overharvesting, it could be particularly useful in informing decision makers about where to establish no-take areas and could therefore aid in improving the sustainability of hunting in tropical forests. Resumen: Tipicamente, la caceria en bosques tropicales es mas intensa cerca de asentamientos humanos, y esto crea gradientes de densidades animales decrecientes hacia esos asentamientos. En el contexto de este patron espacial evaluamos el estatus de animales en los terrenos de caceria de una comunidad indigena en el este de Ecuador. Construimos un modelo espacialmente explicito de interacciones cazador-presa que imitaba la caceria en el poblado e incluia reglas reales de dispersion de animales. Comparamos las predicciones del modelo con las distribuciones de tasas de cosecha y de captura por unidad de esfuerzo de 12 especies cinegeticas. Seis especies eran sobre explotadas en parte de o toda el area, y probablemente dos especies mas eran sobre explotadas, aunque altas tasas de dispersion complicaron la interpretacion. Luego comparamos nuestro metodo con metodos utilizados previamente. Debido a que nuestro metodo proporciona informacion sobre la extension espacial de la sobre explotacion, sostenemos que puede ser particularmente util para informar a tomadores de decisiones sobre donde establecer areas sin captura y por tanto ayudar al mejoramiento de la sustentabilidad de la caceria en bosques tropicales.

This article seeks to extend the enduring focus on the body and bodily substance in Amazonia, which have historically eclipsed other forms of relatedness and ethical practices. Among the Venezuelan Sanema, morality is enacted predominantly through manufactured items rather than solely corporeal expressions of relatedness. While artefacts of all forms are receiving increased recognition in the region, they are often explored within a non-dualist frame that foregrounds inalienability, ownership and subjectification. Yet, the Sanema ethnography reveals that dissolving dualisms in this way suppresses the existence of important categories such as objects. Focusing on how ethical practices are enacted through partible beads and diesel-powered generators, this paper reveals how alienable goods among the Sanema are valued precisely for their 'objectness' rather than their personified qualities.
