Fine‐scale variation in the medium and large‐sized mammal assemblage compositio...
Brandão, Fernanda Colares; Carvalho, William Douglas; Duarte, Herbert O. B.; Rosalino, L. M.; da Silva, Cláudia Regina; Hilário, Renato RichardUnderstanding fine-scale assemblage composition patterns of mammals is important to increase ecological knowledge and support conservation actions. We investigated whether β-diversity of medium and large-sized mammals and its components (replacement and richness difference) are related to distance to major rivers, height above the nearest drainage (HAND), and vegetation height; and whether species interactions ...
Spatiotemporal interactions between jaguars (Panthera onca) and their potential...
Duarte, Herbert O. B.; Rosalino, L. M.; de Toledo, José Júlio; Hilário, Renato Richard; Carvalho, William DouglasAlthough large carnivores usually prefer large prey, in some situations, they may shift their predation patterns towards smaller but abundant prey. The jaguar (Panthera onca) is a large carnivore capable of changing its diet according to prey and habitat availability. Here, we assessed the temporal and spatiotemporal interactions between jaguars and their prey in the Maracá-Jipioca Islands (Northeastern Amazon,...
Editorial: Human impacts on bats in tropical ecosystems: sustainable actions an...
Bobrowiec, Paulo Estefano D.; Carvalho, William Douglas; Rainho, Ana; Webala, Paul W.; Aguiar, Ludmilla M. S.Globally, the most extraordinary biodiversity is in the tropics, spread in a great diversity of vegetation types and habitats. Among the myriad mammalian groups, bats stand out for their remarkable taxonomic, functional, and phylogenetic diversity (Wilson and Mittermeier, 2019). Within the tropics, bats can be found in different vegetation types varying in a gradient of structural complexity from dense ancient ...
A new tool to quantify biodiversity change under landscape transformation
Hilário, Renato Richard; Carvalho, William Douglas; Xavier, Bruna Da Silva; Palmeirim, Jorge M.; Vieira, Marcus Vinícius; Mustin, Karen; Cardoso, PedroIdentifying how species richness or diversity changes with different proportions of natural and anthropized environments in the landscape is important for landscape management for conservation. Here, we propose a new method to assess biodiversity changes in landscapes with varying proportions of habitat types. The algorithm is based on the resampling of individuals recorded in different habitats considering bot...
Global systematic map of research on bats in agricultural systems
Xavier, Bruna Silva; Rainho, Ana; Santos, Ana M. C.; Vieira, Marcus Vinícius; Carvalho, William DouglasIntroduction: The conversion of natural habitats to agricultural systems is one of the main global threats to bats. Here, we aimed to develop a systematic mapping to identify publication trends and research gaps in studying bats and agricultural systems. Methods: We reviewed 309 studies published between 1990 and 2021 that sampled bats in agricultural systems or evaluated the effect of these systems on these an...
The relative importance of forest cover and patch-level drivers for phyllostomi...
Carvalho, William Douglas; Rosalino, L. M.; da Silva Xavier, Bruna; de Castro, Isaí Jorge; Hilário, Renato; Marques, Tiago MirandaContext Analyze the multiple dimensions of biodiversity under a local and landscape lens in natural habitats, such as Amazonian savannas, is fundamental for the conservation of species and ecosystems. Objectives We aim to explore how landscape forest cover and patch-level variables affect the patterns of species abundance, functional traits, and taxonomic, functional and phylogenetic α-diversity of Phyllostomid...
Temporal activity of rural free-ranging dogs: implications for the predator and...
Carvalho, William Douglas; Rosalino, L. M.; Godoy, Maíra Sant’Ana M.; Giorgete, Marília F.; Adania, Cristina Harumi; Esbérard, Carlos E. LustosaDomestic or free-ranging dogs (Canis lupus familiaris) can have deleterious effects on wildlife, acting as predators or competitors to native species. These impacts can be highly important in fragmented pristine habitats or well-preserved areas located in human dominated landscapes and where biodiversity values are usually high, such as those in southeastern Brazil. Here we explored the level of overlap or mism...
