Onças subterrâneas: primeiro registro de uma onça-pintada (Panthera onca) usando uma toca de tatu-canastra (Priodontes maximus) [PDF]
Notas sobre Mamíferos SudamericanosThere are several behavioral adaptations used by mammals to reduce the metabolic costs of preventing homeostasis disruption caused by excessive heat, such as seek shaded places. Burrows are great thermal refuges that provide buffered cooler microclimates.

Living in the Pyrocene: Assemblage-Wide Terrestrial Vertebrate Responses to Mega-Fires in the Pantanal Wetlands. [PDF]
Ecol EvolMore than 60% of Serra do Amolar within the Pantanal Wetlands, Brazil, was burned in 2020. Nine vertebrate species showed a dependency on forest areas, which are more vulnerable to fires in this region, despite the fire not having shown a direct effect on the occupation.

Divergence Across Niche Dimensions Reveals Species' Ecological Roles. [PDF]
Ecol LettNatural history gaps hinder our understanding of species' ecological roles and their contributions to ecosystem processes. Using an integrative framework, we analysed multiple niche dimensions of co‐occurring xenarthran insectivores, revealing divergent trophic, spatial and temporal patterns that reflect distinct ecological roles. Our results challenge

Fecal DNA Identifies a Disjunct Population of an Endemic Deer (Mazama jucunda) From the Atlantic Forest, Brazil. [PDF]
Anim GenetABSTRACT Limited knowledge of brocket deer distribution persists due to their elusive behavior and the morphological similarities among species. A population of red brocket deer (genus Mazama) was recently discovered in the Rio Doce State Park (PERD), a protected area within the Brazilian Atlantic Forest; however, species‐level identification was ...

Fleas and lesions in armadillo osteoderms. [PDF]
J Anat, 2023 Study of lesions caused by flea's ‘bites’ in the bones on the backs of armadillos show that they are actually made by the host's own osteoclasts, not by the flea's own masticatory apparatus. Panels (a, c, e) are reconstructions from high‐contrast resolution X‐Ray Microtomography and (b, d, f) backscattered electron mode scanning electron microscopy ...

Large- and medium-bodied terrestrial mammals of the Upper Berbice region of Guyana [PDF]
Check List, 2020 Large mammals are key contributors to forest ecosystems globally, but Neotropical mammal populations are understudied. We employed remotely triggered camera traps and track surveys to assess the mammal community in the newly accessible upper Berbice ...

Diversity and Activity Patterns of Medium-Sized and Large Terrestrial Mammals in Agroforests of a Peruvian Amazon Rainforest Region. [PDF]
Ecol EvolWe studied species richness and activity patterns of medium‐sized and large terrestrial mammals in agroforests located in the northern buffer zone of Tambopata National Reserve, Peru. The agroforests harboured a high number of mammal species, with species richness increasing alongside greater structural complexity of vegetation.

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy. [PDF]
Anat Rec (Hoboken)Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.
