Acta Zoologica, EarlyView.ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

Conservation Biology, EarlyView.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

A 50‐year perspective on the use and potential of artiodactyl calcanei in bone adaptation studies
Biological Reviews, Volume 101, Issue 1, Page 437-485, February 2026.ABSTRACT Sheep and deer calcanei are important models for studying cortical (compact) and trabecular (cancellous) bone adaptation because they are amenable to direct strain measurement (due to lack of surrounding muscles), experience relatively simple/unidirectional bending, exhibit osteon remodelling, and have the most pronounced regional variations ...

Nest niche overlap among the endangered Vinaceous-breasted Parrot (Amazona vinacea) and sympatric cavity-using birds, mammals, and social insects in the subtropical Atlantic Forest, Argentina [PDF]
, 2017 Many forest bird species require tree cavities for nesting, and share this resource with a diverse community of animals. When cavities are limited, niche overlap can result in interspecific competition, with negative consequences for threatened ...

Fallen Logs Act as Natural Bridges Over Rivers in a Tropical Wet Forest
Biotropica, Volume 58, Issue 1, January 2026.We studied how vertebrate species used logs as bridges over rivers in a tropical rainforest. Most mammals present in the area used logs, but the frequency and probability of crossing varied widely among species, between seasons, and in relation to the dimensions of the log and the river below.

Host‐Driven Genetic Diversity of Leptospira in the Americas: A Continental Perspective
Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.Leptospira is a genetically diverse genus of spirochetes comprising over 68 species, including several pathogenic taxa such as L. interrogans, L. santarosai, L. noguchii, and L. weilii. These bacteria infect a wide range of vertebrates, especially mammals, with infected animals serving as renal carriers that excrete the pathogen through urine.
