The genus Caenolestes is the most species-rich of the marsupial order Paucituberculata. Two species inhabit Colombia (and also occur in Ecuador) with a discontinuous distribution that has not been accounted for in previous studies— Caenolestes fuliginosus known from the Central and Eastern Andes, and C. convelatus restricted to the Western Andes. Here, we present new and noteworthy records of Caenolestes from the Western Andes at the distributional gap of C. convelatus , and outside the known range of C. fuliginosus. We present detailed comparisons using discrete and continuous diagnostic morphological characters, with type material and additional specimens collected nearby, to assess the identity of the new specimens. We performed statistical analyses at species and subspecies levels, and used a principal components analysis to explore the ordination of the new specimens in morphological space. We found that although these specimens are from the Western Andes, they present traits similar to C. fuliginosus and show great overlap with the morphospace of that species. The new records did not differ statistically with C. fuliginosus or any of its subspecies, but they differed in 20 craniodental measurements from C. convelatus. We also report differences at subspecies level within and between species. Based on these observations, we identified these records as C. fuliginosus , expanding its known distribution to the midportion of the Western Andes, across de Cauca valley. We discuss the biogeography of these 2 species in light of the new data and the context of high Andean habitats, especially regarding the contrasting biogeographical patterns found in other taxa in the Northern Andes. Finally, we discuss the need for a new and exhaustive review of the systematics and biogeography of the genus. [ABSTRACT FROM AUTHOR]

We report here for the first time the occurrence of the diogenid hermit crab species Diogenes curvimanus from the Canary Islands, which has been recorded previously from Atlantic European waters and the Mediterranean Sea. The species had been placed under the synonymy of D. pugilator until recently, and is the sole representative of Diogenes known from the islands. The specimens studied were observed between 2019 and 2023, suggesting that these could have recently settled into local habitats and developed a population capable of reproducing.

We are reporting for the first time the presence of the crab Macropipus rugosus (Doflein, 1904) (Polybiidae) in the Canary Islands. This finding is based on the collection of three individuals off Tenerife. The collection, at coordinates 28°10′38″N, establishes a new northern distribution limit for this species. The species was previously known from tropical and subtropical seas off the west coast of Africa, has recently been reported in the waters of Cape Verde, and now we report it for the Canary Islands.

We are reporting for the first time the presence of the hermit crab Pagurus chevreuxi (Bouvier, 1896) (Paguridae) in the Canary Islands. This finding is based on the collection of three individuals and the sighting of several additional specimens on the coast of Lanzarote. The collection, at coordinates 28°55′N, establishes a new southern distribution limit for this species. The species' geographical distribution aligns perfectly with the typical Atlanto-Mediterranean biogeographic pattern, which is characterized by benthic species showing a clear affinity for warm-temperate waters.

The passerine superfamily Certhioidea lacks a complete phylogeny despite decades of recognition as a clade and extensive systematic work within all its constituent families. Here, we inferred a near-complete species-level phylogeny of Certhioidea from a molecular supermatrix, including the first comprehensive sampling of the wrens (Troglodytidae), and used this phylogeny to infer its biogeographic and diversification histories. We also inferred an expanded phylogeny including nearly 100 putative phylospecies previously documented in the literature, and we found that including this diversity had notable impacts on the inferred evolutionary history of Certhioidea. This phylospecies-level tree documented a few instances of species paraphyly, some previously described in the literature and some novel. We found that Certhioidea originated largely in Eurasia and dispersed into North America five times in the last 20 million years, including at the origin of the "New World certhioids," wrens and gnatcatchers, a clade herein named Orthourae. After this initial dispersal event, both wrens and gnatcatchers diversified extensively across the hemisphere, with both lineages repeatedly crossing between continents. However, we detected no notable impact of the formation of the Isthmus of Panama on the frequency of dispersal events between North and South America. The inclusion of phylospecies altered this biogeographic inference in some portions of the tree but overall was largely consistent. With species-level sampling, we found that diversification rates within Certhioidea were largely constant through time with a detectable deceleration toward the present. By contrast, phylospecies-level sampling recovered a different diversification history with a significant rate increase at the crown node of Orthourae after dispersing into the Americas and increased speciation rates particularly within the genera Polioptila and Henicorhina. This largely resolved phylogeny for Certhioidea has yielded important insights into the evolutionary history of this group and provides a framework for future comparative work on this fascinating clade.

A new species of Pimelodella is described from the rio Paraguai basin in Mato Grosso do Sul and Mato Grosso States, Brazil. The new species distinguishes from all other members of the genus based on a unique combination of characteristics, which include: dorsal profile straight from snout to dorsal-fin, maxillary barbel reaching at least the anal-fin terminus when parallel to main body axis, robust dorsal-fin spine bearing small spinules along three-fourths of its posterior margin, 41-42 total vertebrae (rarely 43 or 44), 13-23 large and retrorse blades at the posterior margin of the pectoral-fin spine, and dorsolateral region of body slightly darkened. This study also discusses the ichthyofaunal similarities between the Paraguai and Amazon basins, shedding light on their biogeographic history. Additionally, the research includes considerations about the sexual dimorphism of Pimelodella and provides an identification key for the Pimelodella species found in the Paraguai basin.

The amphipods of the genus Hyalella have many endemic species throughout South America, and these may have poorly studied associated species as epibionts. The aim of the present study was to review the literature on the presence of the protozoon Lagenophrys lenticulata (Kellicott, 1885) on species of Hyalella and contrast the results with the geographical distribution of the reported hosts. The literature records the presence of L. lenticulata on populations of H. azteca from Canada, Mexico and the United States of America, and on populations of H. curvispina from Uruguay. The literature also reports that H. curvispina is widespread throughout southern South America, including Argentina and Chile, and that it would be possible to find the presence of epibionts on other populations of H. curvispina. The corresponding biogeographical and evolutionary topics are discussed. [ABSTRACT FROM AUTHOR]

A taxonomic treatment of the latiuscula species subgroup of subgenus Pinacodera Schaum, genus Cymindis Latreille with a key to species. Twelve species and two subspecies are treated, eleven (ten species, one subspecies) are described as new. One species, C. punctifera (LeConte), is re-ranked as a subspecies of C. punctifera (sensu lato). Listed alphabetically are the species and subspecies: Cymindis apache, new species (Ramsey Canyon, Cochise County, Huachuca Mountains, Arizona, U.S.A.); C. crenatoverpa, new species (Volcán Ceboruco, Nayarit, México); Cymindis cuyuteca new species (Cuautla, Jalisco, México); C. geminata, new species (Cuernavaca, state of Morelos, México); C. huichilobos, new species (km 117, Oaxaca-Puerto Angel road, state of Oaxaca, México); C latiuscula (Chaudoir) (Dzibilchaltun Archaeological Zone, ca. 16 km north of Mérida, Yucatán, México); C. punctifera punctifera LeConte, new rank (Madera Canyon, Santa Rita Mountains, Pima County, Arizona, U.S.A.); C. punctifera toltec, new subspecies (Mazatlán, Sinaloa, México); C. rugofrons, new species (19.5 km NW Los Volcánes, Jalisco, México); C. tonatiuh, new species (15 km SE Nochixtlán, Oaxaca, México); C. yaqui, new species (Cave Creek Canyon, S. Fork, Chiricahua Mts., Arizona, U.S.A.); C. zacapa new species (12-14 km S. San Lorenzo, Departamento Zacapa, Guatemala); and C. zapotec new species (San Gabriel Mixtepec, Oaxaca, México). Cymindis punctifera (LeConte 1884), a junior synonym of C. cribrata (Chaudoir 1875), is the valid species name because the latter is a junior secondary homonym of Cymindis cribrata LeConte 1859 (= C. pilosa Say 1823). Ecologically, the species of the latiuscula subgroup are geophile or arboreal mesophiles, occupying tropical wet and dry, oak- pine [lowland to montane], and cloud forests, to scrubby desert vegetation, their resting places are under bark or bromeliads. These beetles are active in year-round, principally March to September. They may be found from sea level to 3060 m, with most found below 1800 m. [ABSTRACT FROM AUTHOR]

Irazú volcano is one of the highest peaks in Costa Rica; it constitutes one of the few sites with the plant association known as montane and sub-paramo. The research aimed to characterize the structure and composition of this ecosystem considering two altitudinal floors (montane and subpáramo). Three 1000 m² plots per forest type were established, in which botanical identification was developed, and diameter and total height were measured. In both forests, the diameter distributions were adjusted to the different forest models with a basal area of 31.68 m² ha¹ in montane forest and 4.67 m² ha¹ in subpáramo forest. Regarding the vertical structure, the montane forest reached a maximum height of 21 m with three well-defined strata; on the other hand, the subpáramo reached 8 m and did not differentiate strata. Regarding the diversity analysis, it was determined that both forests have significant differences; the montane forest reported 20 species, while the subpáramo only had six species. Comarostaphylis arbutoides is the most important species for both communities. The most important conclusion is that the study area can be considered an altitudinal island; it represents a site of high value for the conservation and research of the sub-paramo plant community. The structure is straightforward in species, its area is minimal, and it is very vulnerable to volcanic events, which shows its value for conservation and study. [ABSTRACT FROM AUTHOR]

The blackish small-eared shrew, Cryptotis nigrescens (Allen, 1895), is a blarinine soricid that occurs in high-elevation premontane wet forest and cloud forest in the Central American countries of Costa Rica and Panama. The species is taxonomically monotypic, although it exhibits size variation that manifests as a gradual increase in size from northwest to southeast. Habitat loss is currently the greatest threat to the species' existence, although populations in the few areas where C. nigrescens has been studied appear to be healthy, and the International Union for Conservation of Nature (IUCN) classifies it as a species whose conservation status is "Least Concern" (LC). We include a complete synonymy for the genus CryptotisPomel, 1848. La musaraña negruzca de orejas pequeñas, Cryptotis nigrescens (Allen, 1895), es un sorícido blarinino que se encuentra en los bosques húmedos premontanos de gran altura y en los bosques nubosos de los países centroamericanos de Costa Rica y Panamá. La especie es taxonómicamente monotípica, aunque exhibe una variación de tamaño que puede manifestarse como un aumento gradual de tamaño del noroeste al sureste. La pérdida de hábitat es actualmente la mayor amenaza para la existencia de la especie, aunque las poblaciones en las pocas áreas donde se ha estudiado C. nigrescens parecen saludables, y la Unión Internacional para la Conservación de la Naturaleza (UICN) la ha clasificado como una especie cuyo estado de conservación es "Least Concern [Preocupación Menor]" (LC). Incluimos una sinonimia completa para el género CryptotisPomel, 1848. [ABSTRACT FROM AUTHOR]

Evolutionary biologists recognize that understanding the phylogenetic history of closely related species is challenging without considering their population genetics history. The taxonomy of Magnolia sect. Talauma in Cuba has long been debated, with several changes in taxon delimitations. All these taxonomic revisions were based exclusively on leaf morphological characteristics of a few individuals, limiting their ability to elucidate taxon boundaries. Recent studies have focused on conservation genetics and species delimitation of Cuban magnolias, based on ecological, morphological and genetic data. Here, we use full plastome sequences and microsatellite data to infer phylogenetic relationships and potential historical migration events among species in Magnolia sect. Talauma in Cuba. Bayesian phylogeny and TreeMix were used to understand the phylogenetic relationships. Based on this, Magnolia sect. Talauma in Cuba does not comprise a monophyletic group. The data continue to show a highly supported unresolved species complex in the taxa of Magnolia subsect. Talauma from north-eastern Cuba. From a taxonomic point of view, our results do not entirely support the most recent taxonomic review proposed for the family in Cuba. [ABSTRACT FROM AUTHOR]

The genus Limia is endemic to the Greater Antilles with a single species in Cuba, Limia vittata , widespread in lowland ecosystems. The limited data available regarding its population structure suggest that its levels of intraspecific divergence are lower compared to other Cuban poeciliids. Furthermore, little is known about the dispersal pathways and demographic changes experienced by present-day populations. By analysing two mitochondrial markers and testing scenarios of dispersal and vicariance, we provide insights into the evolutionary history of L. vittata. Here, we show that this species is formed by three genetically differentiated and geographically delimited groups of populations. We also found moderate intraspecific divergence and a mtDNA pattern of high haplotype diversity and low nucleotide diversity which is consistent with a rapid demographic expansion. Our Bayesian analysis recovered dispersal from eastern to western Cuba as the most likely scenario explaining the current distribution of this species. Limia vittata exhibited a distinct regional distribution of haplogroups that corresponds to major core landmasses within Cuba, along with a signature of rapid population expansion during relatively recent palaeoclimatic changes that occurred during the formation of the archipelago. Similar phylogeographic patterns have been identified in other freshwater and terrestrial taxa on the island. [ABSTRACT FROM AUTHOR]

Genetic divergence among isolated populations is not always reflected in phenotypic differentiation. We investigated the genetic and phenotypic differentiation in Diglossa cyanea (Thraupidae; Masked Flowerpiercer), a widely distributed species in the tropical Andes. We found strong evidence for 2 main lineages separated by the Marañón River valley in the Northern Peruvian Low (NPL). These 2 lineages show a deep sequence divergence in mitochondrial DNA (mtDNA; ~6.7% uncorrected p-distance, n = 122), spectral frequency and song structure (with exclusive final whistles in southern populations, n = 88), and wing length (the northern populations are smaller, n = 364). The 2 divergent D. cyanea mitochondrial lineages were not sister to each other, suggesting a possible paraphyly with respect to D. caerulescens (Bluish Flowerpiercer) that remains to be tested with nuclear genomic data. No genetic variation, size difference, or song structure was observed within the extensive range of the southern group (from the NPL to central Bolivia) or within all sampled northern populations (from the NPL to Venezuela). These vocal differences appear to have consequences for song discrimination, and species recognition, according to a previously published playback experiment study. We propose that the southern taxon be elevated to species rank as D. melanopis, a monotypic species (with the proposed name Whistling Masked-Flowerpiercer). In turn, we provide a redefinition of D. cyanea (Warbling Masked-Flowerpiercer), which is now restricted to the northern half of the tropical Andes as a polytypic species with 3 subspecies (tovarensis, obscura, and cyanea). Based on our results, the subspecies dispar should be treated as a junior synonym of cyanea. Our study highlights the need to continue amassing complementary data sets from field observations, experiments, and collection-based assessments to better characterize the evolutionary history, biogeography, bioacoustics, and taxonomy of Neotropical montane birds.

It is repeatedly stressed the need to characterize the extant biodiversity in tropical ecosystems. However, inventory studies are still progressing slowly in dry ecosystems, leading to the underestimation of their true biodiversity and hindering conservation efforts. In this study, we present primary and secondary data, along with an updated list of amphibians and reptiles from two localities in the São Francisco-Gurguéia region in Piauí. Additionally, we compare the species composition between nine areas within the Caatinga, which were sampled using standardized methods over the past ten years, to examine broader spatial patterns of community composition. To survey reptiles and amphibians, we employed similar methods and sampling efforts in two areas within the Serra das Confusões National Park (SCNP) region. Our surveys recorded a total of 73 species of amphibians and reptiles, of which 24 are new distribution records for the SCNP region. Consequently, our findings increase the known herpetofauna in the region to 94 species. Despite their proximity, the two sites in the SCNP region exhibited only 42% similarity in species composition, and they differed significantly from other areas within the Caatinga. Furthermore, even the closer Caatinga areas presented differences in species composition, highlighting the necessity to evaluate biodiversity across the landscape and contribute to understanding biogeographic patterns.

Background and aims: Hippeastrinae originated in South America and then migrated to North America. Mexico represents a center of diversity of the group and the Mexican Transition Zone concentrates the highest species richness. The aims of this work were to estimate the species richness of Hippeastrinae in Mexico, to analyze the geographic distribution and to identify areas of richness. M&M: A database was created from herbarium specimens, electronic resources, and literature. Using geographic information systems, we estimated the species richness and distribution by state, region and biogeographic province; vegetation type, latitude, longitude and elevation. Additionally, the species richness was analyzed using a grid cell of 50 × 50 km2 . Results: Fourty-five species of Hippeastrinae occur in Mexico. The database integrated 1359 georeferenced records. Hippeastrinae was recorded in 31 states, in all regions, biogeographic provinces and vegetation types. It occurs from 15.9 to 31.8° latitude, from 88.2 to 118.3° longitude and from 0 to 3508 m a.s.l. San Luis Potosí had the greatest species richness and endemism. The Neotropical region host the largest number of species. The Sierra Madre Oriental province harbors the greatest species richness and the richest cells. The group resulted particularly diverse in coniferous and oak forest, xeric shrubland and agriculture-aquaculture farmland. Conclusions: Hippeastrinae exhibit a modern neotropical pattern of richness and distribution. The species richness and endemism were concentrated in the Neotropical region and the Mexican Transition Zone. The Sierra Madre Oriental is a center of diversity of the group. [ABSTRACT FROM AUTHOR]

This article deals with the hierarchy made by Charles Darwin, in The Origin of Species, of the best geographical conditions for the occurrence of speciation, going from the worst condition, a small and isolated area, to one of better condition, characterized by being large, continuous and which has already gone through fragmentation. And also, that such hierarchy of geographies that promote speciation is at the base of one of the most important biogeographic theories in force, the Refuge Theory. [ABSTRACT FROM AUTHOR]

North American mammals follow a well-established latitudinal diversity gradient in species richness. However, the degree to which species in different mammal clades follow the same latitudinal gradient—and to which each clade contributes to the pattern observed for all mammals remains unknown. Here, we separate the overall mammalian latitudinal diversity gradient by mammal orders and investigate the impact of climate and topography on the distribution of each major mammal clade. We joined an equal-area grid (100 × 100 km cells) of continental North America embedded with environmental variables (n = 10) with mammalian species ranges (n = 753). We used spatial regression models to quantify the relationship between species richness and latitude for all mammals, all mammals excluding select clades, and for each individual subordinate clade (n = 9). We used multiple linear regression and simultaneous autoregressive regression models to determine which environmental variables best explained patterns of species richness for each mammal order. Whereas North American mammals altogether exhibit a strong latitudinal diversity gradient in species richness, most orders deviate from the species richness pattern observed for all mammals and their gradients are weak or entirely absent. Bats (Chiroptera) exhibit the strongest latitudinal gradient—their removal from the pattern for all mammals substantially weakens the total mammalian gradient, more so than when rodents are removed. Environmental variables explain patterns of species richness well for some clades, but poorly for others. The gradient we observe for North American mammals today is likely a combined product of multiple diversification events, dispersals, and climatic and tectonic histories. [ABSTRACT FROM AUTHOR]

Refugia‐based conservation offers long‐term effectiveness and minimize uncertainty on strategies for climate change adaptation. We used distribution modelling to identify climate change refugia for 617 terrestrial mammals and to quantify the role of protected areas (PAs) in providing refugia across South America. To do so, we compared species potential distribution across different scenarios of climate change, highlighting those regions likely to retain suitable climatic conditions by year 2090, and explored the proportion of refugia inside PAs. Moist tropical forests in high‐elevation areas with complex topography concentrated the highest local diversity of species refugia, although regionally important refugia centers occurred elsewhere. Andean–Amazon forests contained climate change refugia for more than half of the continental species' pool and for up to 87 species locally (17 × 17 km2 grid cell). The highlands of the southern Atlantic Forest also included megadiverse refugia for up to 76 species per cell. Almost half of the species that may find refugia in the Atlantic Forest will do so in a single region—the Serra do Mar and Serra do Espinhaço. Most of the refugia we identified, however, were not in PAs, which may contain <6% of the total area of climate change refugia, leaving 129–237 species with no refugia inside the territorial limits of PAs of any kind. Our results reveal a dismal scenario for the level of refugia protection in some of the most biodiverse regions of the world. Nonetheless, because refugia tend to be in high‐elevation, topographically complex, and remote areas, with lower anthropogenic pressure, formally protecting them may require a comparatively modest investment.

Like other meiofaunal organisms, tardigrades suffer from a significant knowledge gap concerning many aspects of their biodiversity. The lack of an up-to-date digital collection with all species and details of limnoterrestrial and freshwater tardigrades in South and Central America is one of the most critical gaps to be filled. Therefore, the present work aims to develop a database containing all valid species of limnoterrestrial and freshwater tardigrades from South and Central America found until 2023 and provide open access to the results. Data for each species were obtained directly from the literature using Google Scholar and the website tardigrada.net. This compiled data resulted in the creation of a database with the species name, author and year of species description, genus, family, class, type country, type location, coordinates (longitude and latitude), if it is aquatic and/or limnoterrestrial, substrate where it was found, the country and location of collection, and manuscript containing the species identification. Furthermore, the coordinates of each occurrence were plotted on maps with political-administrative boundaries and Neotropical and Andean biogeographic regions. In addition, statistical analysis was performed related to the geographic distribution of the sampling effort. From the literature, 2157 records of valid non-marine Tardigrada species, endemic or not, were computed. From these records, 271 species of tardigrades have been identified in the two regions combined, with 223 species in South America and 129 species in Central America. We were able to show that there are still many biases in the sampling of tardigrades in the Neotropical and Andean regions and that further studies are needed on the biogeography of these meiofaunal organisms in these biogeographic regions. We expect this database to help better understand the richness and distribution patterns of limnoterrestrial and aquatic tardigrade species in Central and South America. [ABSTRACT FROM AUTHOR]

Given the speed at which humans are changing the climate, species with high degrees of endemism may not have time to avoid extinction through adaptation. We investigated through teleconnection analysis the origin of rainfall that determines the phylogenetic diversity of rainforest frogs and the effects of microclimate differences in shaping the morphological traits of isolated populations (which contribute to greater phylogenetic diversity and speciation). We also investigated through teleconnection analysis how deforestation in Amazonia can affect ecosystem services that are fundamental to maintaining the climate of the Atlantic rainforest biodiversity hotspot. Seasonal winds known as flying rivers carry water vapor from Amazonia to the Atlantic Forest, and the breaking of this ecosystem service could lead Atlantic Forest species to population decline and extinction in the short term. Our results suggest that the selection of morphological traits that shape Atlantic Forest frog diversity and their population dynamics are influenced by the Amazonian flying rivers. Our results also suggest that the increases of temperature anomalies in the Atlantic Ocean due to global warming and in the Amazon forest due to deforestation are already breaking this cycle and threaten the biodiversity of the Atlantic Forest hotspot.

Ecological factors such as temperature, precipitation, and vegetation type have been reported to influence biogeographic patterns (e.g. species distribution, richness, and endemism) in mammals. In Chile, these patterns only had been explored in selected mammal groups from certain localities. In this study, we describe and analyze biogeographic patterns for all small mammals (marsupials, armadillos, bats, rodents), reported until 2020, in different climatic and ecological regions from continental Chile. Using a compiled database of 89 species, we estimated their distributional similarity, described and characterized richness and areas of endemism using Bayesian and Parsimony Analysis of Endemism, and linked species distribution with conservation status according to the IUCN Red List. We found three similarity units of species distribution based on climate: Arid, Temperate, and Polar; higher richness and endemism in north and south-central Chile; two areas of endemism, one in north and one in south; and a hotspot in south-central Chile. Finally, species of greater conservation concern showed a similar and small distribution range. The concordance in the distribution of the species with Chilean climatic regions (as determined by precipitation and temperature) suggest that the spatial distribution of Chilean small mammals is influenced strongly by those abiotic factors. This also could explain the patterns of richness and endemism and, therefore species hotspots. Variations of climatic factors therefore should be considered in explaining biogeographic patterns and conservation plans of Chilean small mammal species, because species of greater concern tend to be associated and having similar distributional characteristics.

The Northeastern Mata Atlântica freshwater ecoregion (NMAF) is recognized for the high degree of endemism of its ichthyofauna, whose evolutionary and biogeographic histories are still poorly understood. Oligosarcus acutirostris is a freshwater fish species endemic to the NMAF, which is distributed in coastal rivers and streams draining Bahia, Espírito Santo, and part of Minas Gerais states in eastern Brazil. Its widespread distribution in currently isolated river basins along the NMAF prompted this study, which aimed to understand what scenarios would be involved in determining its current distribution pattern, and to contribute to a better understanding of the biogeographic history of the NMAF. For this, mitochondrial and nuclear DNA sequences were analyzed based on samples from different localities along the species distribution, including its type locality. Overall, phylogeographic analyses indicate a strong genetic structure within the species evidenced mainly by the non-sharing of haplotypes between most of the basins analyzed. According to the AMOVA results, the current distribution of haplotypes is better explained by the Pleistocene coastal paleodrainages. The results are also used to test and complement a biogeographic hypothesis previously proposed for the drainages of the NMAF. [ABSTRACT FROM AUTHOR]

Educational communication has been gaining prominence since the 1970s with the integration of information technologies into education, especially in more developed countries, gaining strength in Brazil over the past two decades. Paulo Freire was one of the promoters of this creative perspective of Communication/Education interrelation, pointing to the essentially dialogical nature of communication processes for the formation of a "critical consciousness." However, educational communication can also occur analogically without the use of technologies, such as in the making of signs, posters, models, pamphlets, exhibitions, and similar items. Environmental educational communication can be especially utilized through fast media, such as social networks, with YouTube Shorts, Instagram Stories or Reels, and short TikTok videos, which can be explored for the creation of audiovisual resources, as well as for the production of clips, short films, among others, all of which have a wide reach of environmental educational communication to the current population. The objective of this chapter is to explore the role of environmental educational communication as a tool for the dissemination and conservation of protected areas in the metropolitan region of Rio de Janeiro, Brazil, also known as Baixada Fluminense, presenting an overview of these areas with a focus on the Mário Xavier National Forest (Flona MX). The conservation units of Baixada Fluminense suffer from stereotypes attributed to the social and economic issues of the region, these facts contribute to the invisibility of these green areas, directly affecting conservation. Changing this scenario can come from encouraging society to become active in conservation, taking on the role of protagonists and for that, educomunicação must be present in these spaces, providing information, knowledge, and dissemination of these spaces, making society recognize the importance of protected areas, known in Brazil as Conservation Units. Thus, it was identified that the use of technological resources such as social media are extremely important tools and should be incorporated into communication plans of protected areas, as well as shared management practices should become more present, especially with the technical scientific support of universities, having the Shared Guard Extension Program Flona Mário Xavier, with a great example of integration and success in Baixada Fluminense for conservation.

Between 1970 and 1995, twenty collecting expeditions were carried out in North Korea by the researchers of the Hungarian Natural History Museum. The majority of the North Korean Ichneumonidae (Hymenoptera) material is still waiting for identification; in this paper, the subfamily Campopleginae is treated.

The species Heterophrynus boterorum is endemic to Colombia, and was described in 2013 with just a few specimens. It has morphological variation that may be correlated with environmental conditions, or with isolation processes. We modeled the potential distribution of this species using software Maxent in order to know of other possible occurrence localities and the influence of environmental variables which can condition its presence. Additionally, we contrasted the potential distribution with the National System of Protected Areas of Colombia. The species has a potential distribution in the central region of the Andes in the Cordillera Central and Occidental, which connects all known populations. Precipitation and temperature, especially during the driest season, were the most influential variables in the model, which is coherent regarding the requirements for humidity and climatic stability in Amblypygi. Only one of the known populations is recorded in a protected area, so it is necessary to design better conservation strategies to preserve H. boterorum. [ABSTRACT FROM AUTHOR]

The distributional patterns of the species of the South American freshwater crayfishes of the family Parastacidae were analysed using panbiogeographical track analyses to identify targeted regions of crayfish biodiversity for understanding biogeographical patterns. Two generalized tracks were identified using the track analysis approach: (1) Uruguay and Brazil (Parastacus brasiliensis , P. brasiliensis promatensis , P. buckupi , P. caeruleodactylus , P. defossus , P. fluviatilis , P. gomesae , P. guapo , P. macanudo , P. pilimanus , P. pilicarpus , P. saffordi , P. tuerkayi , P. varicosus); and (2) Central-southern Chile (P. nicoleti , P. pugnax , Samastacus spinifrons , Virilastacus araucanius , V. jarai , V. retamali and V. rucapihuelensis). These areas were exclusive, with no overlap between them. The results indicate the presence of South American Parastacidae crayfish in Atlantic coastal sub-tropical and Pacific coastal temperate wet climate regions with biogeographic similarities to other South American inland water decapods.

The family Characidae is the most diverse group of fishes in the Neotropics with challenging systematics. The three genera Carlana, Parastremma, and Rhoadsia, formerly considered the subfamily Rhoadsiinae, are now included in the subfamily Stethaprioninae. Previous phylogenetic analyses did not include all genera of Rhoadsiinae, specifically Parastremma. Here, we estimated the phylogenetic relationships and divergence times of the genera of Rhoadsiinae (the Rhoadsia clade) relative to the most representative genera of the Characidae. We used six molecular markers from the mitochondrial and nuclear genome to estimate the phylogeny and divergence times. We confirmed the monophyly of the Rhoadsia clade. Furthermore, we estimated that the Central American genus Carlana and the western Colombian genus Parastremma diverged approximately 13 Mya (95% HPD 8.36-18.11), consistent with the early-closure estimates of the Isthmus of Panama (~15 Mya). The genus Rhoadsia, endemic to Western Ecuador and Northern Peru, was estimated to originate at around 20 Mya (95% HPD 14.35-25.43), consistent with the Andean uplift (~20 Mya).

This article aims to present the structural characteristics of the mangrove of the Mariricu River, as well as to identify its plant species. The results presented below were obtained after treatment, analysis and interpretation of data collected in the field, in transects 1, 2, and 3, regarding plant structure, more specifically tree height and diameter at breast height (DBH), as well as data from laboratory-treated sediments. It was observed that the mangroves are exuberant especially on the banks of the river and tidal channels. Four mangrove species were found in the estuary: Rhizophora mangle (L.), Laguncularia racemosa (L.) C.F. Gaertn, Avicennia schaueriana (L.) and Avicennia germinans (L.). [ABSTRACT FROM AUTHOR]

The present article aims to contribute with a proposal for a didactic resource to assist the contents regarding flora and field activities in biogeography. It was developed, from this, the Table of Physiognomic Classification of the Species of Flora, a didactic resource directed to the studies and observations of the species, based on the contributions made by the researcher Silvio Stefenelli. Among the contributions that emerged from this research is the importance of using didactic resources to study biogeographic content in the classroom. It is understood that the use of the didactic resource proposed here will add to the biogeografic classes, as well as make flora studies more practical, allowing the student a greater understanding of the species and the geographic space.

We briefly describe selected results from our thematic project focused on the biodiversity of the Atlantic Forest ("AF BIOTA"), which was jointly funded by FAPESP's BIOTA Program, the U.S. National Science Foundation Dimensions of Biodiversity Program, and the National Aeronautics and Space Administration (NASA). As one of the five most important hotspots of biodiversity in the world, the Atlantic Forest (AF) holds less than 16% of its vegetation cover, yet, amongst the hotspots, it still harbors one of the highest numbers of species, including endemics. By gathering specialists across multiple disciplines (biology, geology, engineering), we aimed to understand how this megabiodiversity was built through time, informing biodiversity science and conservation. Among the results, we trained 18 Master's and 26 Ph.D. students, published more than 400 peer-reviewed papers that improved our knowledge about the forest's biologic and climatic diversity and dynamics through time, developed new analytical methods, produced outreach videos and articles, and provided data to help define biodiversity conservation policies.

A total of 48 new specific records for U.S.A. (apart from 81 new records for various States) and 44 for Canada are realized resulting in 13 new records for the Holarctic biogeoghaphic Region and 50 for the Nearctic Region. Two families, Machuellidae Balogh, 1983 and Microtegeidae Balogh, 1972, seven genera: Neobrachychthonius Moritz, 1976, Poroliodes Grandjean, 1934, Machuella Hammer, 1961, Coartobelba Mahunka, 2001, Microtegeus Berlese, 1916, Lamellobates Hammer, 1958 and Leptogalumna Balogh, 1960, and two subgenera, Subiasella (Lucioppia) Mahunka, 1985 and Indoribates s. str. Jacot, 1929 are also recorded for the first time. [ABSTRACT FROM AUTHOR]

Inga subnuda is one of 31 Inga species endemic to the Brazilian Atlantic Forest and is currently treated as having two subspecies (I. subnuda subsp. subnuda and I. subnuda subsp. luschnathiana). However, due to intermixed leaf and floral traits, these subspecies are difficult to morphologically distinguish. This study aimed to better understand the boundaries of these two subspecies and to test if these taxa should be treated at the species level. Morphological variation and bioclimatic data related to the two subspecies of the complex were assessed using multivariate morphometric analyses and ecological niche modeling. Different groups were recognized using morphological quantitative characters. The climatic space was similar but not identical, and recent climatic cycles that could have shaped the current distributions of the subspecies are discussed. The results of our integrative study suggest the subspecies are distinct species. Thus, we propose changing the status of I. subnuda subsp. luschnathiana to the rank of species. The new taxon is described and illustrated. Inga subnuda é uma das 31 espécies presentes na Floresta Atlântica. A morfologia foliar e floral sobreposta dificulta o estabelecimento de limites e o tratamento taxonômico atual considera Inga subnuda como uma espécie com duas subespécies. Este trabalho visa explorar diferentes linhas de evidências para esclarecer e resolver a delimitação nas duas subespécies. As variações morfológicas e os dados bioclimáticos das duas subespécies foram avaliados através das análises morfométricas multivariadas e a modelagem de nicho ecológico. Os caracteres quantitativos permitiram o reconhecimento de táxons diferentes. O espaço climático foi similar, mas não idêntico, aliás são discutidos os recentes ciclos climáticos que poderiam ter modelado a distribuição atual. Os resultados do nosso estudo integrativo sugere considerar as duas subespécies como duas espécies diferentes, resgatando o status de espécie para I. subnuda subsp. luschnathiana. A nova delimitação de Inga luschnathiana é descrita e ilustrada. [ABSTRACT FROM AUTHOR]

Once biogeography is the bridge between biology and geology, geographic space is the scenery in which the dynamic biota plays on the spatial dimension of evolution. Thus, there are overlapping concepts among correlate sciences and many of them can be traced to myths produced by cultures at the dawn of humankind. If so, early discoveries of geography and geology were inevitably associated to early history of the biogeography, but unfortunately rigid interdisciplinary barriers were constructed separating twin sciences. Although trapped under the dead hand of history, these sciences, coming together in a pluralist perspective, can positively say something about origins. If myths and legends produced scenarios in which concepts were outlined, recovering these tales allows us to understand the epistemological reasons and starting points of modern mainstream of schools and methodologies of analytical biogeography. In addition, exploring key-concepts and identifying its origins improve the quality of teaching, explaining what was previously assumed as objective reality about geographic space. The goal of this work is to get together primeval biogeography and geological and geographical discoveries, enhancing selected regular and contingent events, old myths, early protagonists, and discussing implications and pathways. We conclude that many insights about species, fossils, extinction, endemism and transformism were present among ancient Greeks and Romans, but they were gradually distorted to agree with new obscure trends in the history of the occidental culture.

Herein, a recognition to Juan José Morrone is presented, whose great career, dedication to various branches of evolutionary biology and contributions to different zoological groups have left an indelible mark on the history of science in Mexico. To date, Dr. Morrone has had a great history of publications, including more than 300 scientific works, 35 books that are undoubtedly a reference and a threshold for any course dealing with systematics, biogeography or comparative biology. His great work as researcher does not diminish his work as a teacher, as he has taught 130 courses at different levels of education and gave 120 conferences in Mexico as well as in Latin America. In this work I try to summarize his great career and the impact that his ideas have had worldwide. In addition, I present excerpts from an interview in which we discussed some issues such as his literary influences, his way of working and his way of tackling different problems during scientific work.

An annotated checklist of ground beetles in the family Carabidae from the state of Sonora in Mexico is presented with notes including number of specimens examined, municipios, habitat, vegetation, elevation, and collection dates. The checklist includes 388 taxa, of which 270 are described taxa (included are 19 subspecies and 1 hybrid) and 118 are unnamed morphospecies, in 92 genera representing 35 tribes. Dot maps display where specimens were collected. Three new species are described, with corrected keys and images: Calathus mcclevei, new species (type locality: Mexico, Sonora, Municipality of Yécora, 10 km south of Yécora, ca. 28.278° N 108.926° W); Calathus tigrinus, new species (type locality: Mexico, Sonora, Municipality of Nacozari de García, Rancho El Tigre, 28.3 km (by air) WNW Bavispe, Sierra El Tigre, 30.58988° N 109.20811° W); and Amblygnathus balli, new species (type locality: Mexico, Sonora, Municipality of Fronteras, Rancho Capulín, 23.5 km (by air) WSW Fronteras, Sierra Buenos Aires, 30.76167° N 109.82361° W).

The present work aimed to treat and discuss the conceptualization of Biogeography, as one of the fields of study of Geography; of Phytogeography, sub-area of Biogeography, and of Phytosociology, as a sub-branch of Phytogeography, demonstrating the close connection between these and geographic science. As methodological processes consisted of literature review on the subject, document analysis on electronic sites, elaboration of a schema and explanatory table. The research points out that Physical Geography created subareas that aimed to understand natural phenomena in integral parts, Biogeography, for example, branched out into distinct parts such as Phytogeography and Phytosociology to understand the spatialization and organization of plant communities, and above all, characterize them.

There are no studies in the region of the coffee landscape at detailed scales that can offer criteria and empirical inputs for agrarian policy decision-making. This research strengthens the gtp method (Geosystem, Territory, and Landscape), going beyond the traditional "geosystem", as it proves its ability to descend to the scales of "geofacies" and "geotopos", thus ensuring an approximation to the coffee landscape much more detailed. Based on the biophysical and socioecological information of three geotopos of the mountainous area of Ibagué, a study of the coffee landscape is carried out through the geosystem's theory of Bertrand's gtp method. As product, an integrated vision of this landscape is exposed to scales of geofacies and geotopos, and it is demonstrated that these spatial units and their empirical contents can serve as inputs for the elaboration of a scientific study of the agrarian landscape's ecology, according to the principles of the Bertrandian epistemology. Based on these results, public policy recommendations are formulated to manage coffee agrosystems, given their high environmental impacts. [ABSTRACT FROM AUTHOR]

Understand the role of the drivers in vegetation pattern is essential in ecology since diversity plays a major role in the stability and maintenance of plant communities. The murundus are small and scattered earthmounds with a differentiated flora of its surrounding. In our study site (Campo Maior, Piauí, Northeastern Brazil), we classified them in three categories: presence of carnaúba (PC), presence of tucum (PT), and with the absence of palm trees (AP). Here, our goals were (1) to explore alpha diversity using the richness estimator and abundance distribution rank, expecting that palm trees could influence the richness of plant species on murundus; (2) analyzing the species richness-area relationship in the murundus, following the assumptions that the largest one holds more species; (3) find the changes in the species composition (beta diversity) between the three categories of murundus, assuming which the presence of palm trees influence the species composition; and (4) investigate if the distance between murundus is a decisive factor in the species composition, where the closest murundus are the most similar in species composition. Ours results showed that palms trees do not influence the richness of the murundus, the largest murundus are the richest ones, and the turnover predominantly determines beta diversity in the different murundus categories. Furthermore, the distance between the murundus did not determine its floristic similarity. Overall, we demonstrated which the species of palm trees are not the main drive of the plant assemblage in the murundus, however its size comprises a major factor in the richness, with great species substitution, which explains the high plant diversity.
