. Tropical moist forests are complex and diverse ecosystems threatened by human-induced disturbance. Despite recent advances in the study of the impact of land-use change on mammal diversity, there is a lack of research about which factors affect mammal assemblages within fragmented landscapes in Colombia. Herein, we investigate how medium and large-bodied mammals in a fragmented landscape respond to landscape characteristics, identifying how they affect species richness and functional diversity. We sampled eight forested patches in the Middle Magdalena Valley in central Colombia and modeled mammal functional diversity (functional dispersion and evenness) and species richness as a function of landscape variables (i.e., patch size, patch shape, landscape connectivity, and forest fragmentation). Forest fragmentation was the most important variable explaining mammal species richness and functional diversity (measured as functional dispersion). Species richness, functional dispersion, and the number of functional groups were increased in less fragmented forest patches. Conversely, functional evenness exhibited the opposite trend. Taken together, these results show that mammal assemblages in forest patches within forest-dominated neighborhoods support both a higher diversity and a broader spectrum of ecological functions but are less resilient to environmental perturbations. We highlight the importance of forest cover for providing critical habitat for both generalized and specialized mammals in fragmented landscapes. Overall, our findings reinforce the importance of defining conservation actions for minimizing the impact of human activities on the remaining native forests, as they are fundamental for maintaining wild mammals and the ecological processes in which they participate. dispersión funcional).

. The restingas are an important component of the Atlantic Forest, affected by anthropic impacts along the Brazilian coast. The mastofauna that occurs in these environments is little known, especially in the north-east of the country. This study characterized the richness, abundance and composition of small mammal species in arboreal restinga areas in the state of Sergipe, north-eastern Brazil. Sampling was performed monthly, from September 2017 to August 2018. An effort composed of 8188 trap-nights with Sherman traps and 1782 trap-night with pitfall traps resulted in the capture of 120 individuals from 10 species; four marsupials ( Didelphis albiventris , Marmosa demerarae , Marmosa murina, and Marmosops incanus ) and six rodents ( Calomys sp., Cerradomys vivoi , Oligoryzomys sp., Phyllomys blainvilii , Rhipidomys mastacalis, and Trinomys sp.). Phyllomys blainvilii is a new record for the state. The observed richness corresponds to 73% of that estimated by Jackknife 1 (13.6 ± 1.5 species). Marmosops incanus and R. mastacalis were the most abundant, corresponding to 84% of the individuals captured. The community composition differs from the restingas of other regions of Brazil, but the majority of the species correspond to a subset of those found in the Atlantic Forest of the region. The locality presented the greatest richness of small mammals in areas of the Atlantic Forest of Sergipe, reinforcing the importance of the preservation of these areas and contributing to understanding the mastofauna in the restingas. This study also presents an updated list for this group in the state. regiões do Brasil, mas a maioria das espécies corresponde a um subconjunto das encontradas nas áreas de Mata Atlântica da região.

. Dietary studies of insectivorous bats are critical for a comprehensive analysis of their ecological role in pest control. Several factors including seasonality, reproductive status and sex may influence dietary specialization. However, data on insectivorous bat diet are scarce, especially in Mormoopidae family. Here, we analyzed the dietary variation of Mormoops megalophylla (Peters, 1864) between sexes, reproductive states and climatic seasons in Macaregua cave, located in Northeastern Andes of Colombia. We collected fecal samples and vaginal smears from 377 individuals. We assess differences between sexes in the frequency of insect consumption and we estimate dietary breadth in reproductive and non-reproductive bats. Moormops megalophylla has a highly specialized diet, selecting primarily for Lepidoptera insects. There were no differences between sexes, but wider dietary breadth was found in reproductive bats in comparison to non-reproductive bats. Probably, the specialization on Lepidoptera insects is explained by the high amounts of caloric energy that these insects can offer. It was remarkable the upward trend in Lepidoptera consumption from reproductive bats during the wet season, when moths are available. By contrast, non-reproductive bats increased Lepidoptera consumption in the dry season, possibly to prepare for the next reproductive events. suggests variations between climatic seasons and reproductive states; that is, when bats are reproductively active, they increase the amount of Lepidoptera consumption in the wet season to supply their energy requirements during reproduction.

. The Pantanal, the world’s largest wetland, is a biodiversity hotspot and home to several threatened species. The growth and transition of the local economy are a major threat to the ecosystem, and sustainable income sectors need to be established. The local economy is based mainly on cattle farming, while ecotourism has recently become important. Our study was conducted in two subregions of the Brazilian Pantanal, the northern subregion Poconé in Mato Grosso and the southern subregion Nhecolandia in Mato Grosso do Sul. Our results indicate that the two main economic sectors, cattle farming and ecotourism, can support sustainable development when operated at a small scale. Traditional cattle farming had no negative effect on mammalian wildlife richness or abundance in either of our study areas, whereas ecotourism did not affect species abundance but did affect species richness in a few cases. These results are derived from a ten-month camera-trap study (middle of July to middle of October 2010, end of December 2012 to beginning of March 2013, and middle of August to end of November 2013) conducted in both subregions.

. Neotropical Felidae as hosts of zoonotic agents in Brazil. Mammals play a central role in the cycle of several zoonosis, the study of their prevalence and distribution is extremely important to prevent outbreaks and create prophylaxis mechanisms. Wild feline species have increasingly in contact with humans, exposing them to possible overflow or sharing of various pathogens and participating in the cycle of numerous zoonosis. Our objective was to investigate the participation of Brazilian feline species in zoonotic cycles, through secondary data analysis. We found records of 19 zoonosis for 10 feline species, including two caused by viruses, five by nematodes, four by protozoa, and eight by bacteria. The zoonosis with highest prevalence caused by viruses was rabies, protozoa was toxoplasmosis, bacteria were brucellosis and leptospirosis, while by nematodes were hookworm and toxocariasis. The species Leopardus pardalis , Leopardus tigrinus , Panthera onca , and Puma concolor presented highest number of records of pathogens and wider distribution of records through Brazilian regions. Records of these pathogens occurred mainly in the Central West and Southeast regions of Brazil. The role of the members of family Felidae as reservoirs of agents of several lethal zoonosis is observed, although leptospirosis presents a register of different serovars, including some non-pathogenic to the humans. These results bring to light the importance of preserving and maintaining the natural habitats of these species as a public health measure, in order to prevent the proliferation of these zoonosis, both for humans and animals. The preservation of feline natural environments could minimize possible pathogen exchanges between these species and domestic animals and, consequently, with humans, as well as reducing the likelihood of their direct contact with felines.

. Population density is a key parameter in conservation, but remains a challenging metric to obtain for rare and cryptic species. We designed a camera trap array targeting the elusive giant armadillo ( Priodontes maximus ), estimated densities using spatially explicit capture-recapture models, and compared these with estimates from a previous eight-year telemetry study in the area. Density from the six-month camera trap survey (7.69 individuals/100km 2 ) is nearly identical to that from the intensive telemetry study (7.65 ind./100 km 2 ). We recommend the use of systematic camera trap arrays, which are much less expensive and time consuming, to obtain insights on the population status of elusive species across the Neotropics and inform conservation. estimativas de densidade de um levantamento de curto prazo de armadilhas fotográficas com um estudo de telemetria de tatu canastra ( Priodontes maximus ). A densidade de populações é um parâmetro chave em conservação e ecologia, mas é uma métrica difícil de se obter para espécies raras e de hábitos crípticos. Nós desenhamos uma matriz de armadilhas fotográficas para capturar o elusivo tatu canastra ( Priodontes maximus ), estimamos sua densidade usando modelos de captura e recaptura espacialmente explícitos, e comparamos essa estimativa com àquela obtida em um estudo anterior de oito anos de telemetria realizado na mesma área. A densidade obtida através do levantamento por armadilhas fotográficas com duração de seis meses (7.69 indivíduos/100km 2 ) é praticamente idêntica àquela obtida no estudo intensivo de telemetria (7.65 ind./100 km 2 ). Nós recomendamos o uso de matrizes sistematizadas de armadilhas fotográficas, que possuem um menor custo financeiro e em termos de mão de obra, ao longo da região Neotropical para obter conhecimento sobre o status populacional de espécies elusivas e informar medidas de conservação.
