Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...

When Raptors Are Away, Opossums Will Play: Woolly Opossums as Carrion Feeders in Harpy Eagle Nests

Biotropica, Volume 57, Issue 6, November 2025.
Scavenging by New World marsupials is rarely documented. We recorded woolly opossums (Caluromys lanatus) scavenging prey remains from a Harpy eagle’s nest in central Brazil. The low overlap in activity periods between the two species may facilitate the behavior observed here.

Wild Divergence: Molina's Hog‐Nosed Skunk (Conepatus chinga) and South American Coati's (Nasua nasua) Responses to Landscape Changes in the Highly Neglected Uruguayan Savannah

Austral Ecology, Volume 50, Issue 9, September 2025.
The South American coati (Nasua nasua) has a greater chance of occupying areas with more forests. The Molina hog‐nosed skunk has a greater occupancy in native grasslands and crop farm areas. The coati has a smaller chance of occupying areas of crop farming and native grasslands.

Surviving in the Amazon Arc of Deforestation: Richness and Defaunation of Mammals in Priority‐Protected Areas of the Brazilian Midwest

Austral Ecology, Volume 50, Issue 7, July 2025.
We found rich and compositionally different assemblages of medium and large‐sized mammals in protected areas on the southern edge of Amazon. However, both have high rates of mammal defaunation. We argue that anthropogenic threats in the Amazon Arc of Deforestation are eroding large ungulate populations, especially peccaries.

Effects of an Extreme Weather Event on Primate Populations

American Journal of Biological Anthropology, Volume 186, Issue 1, January 2025.
ABSTRACT Objectives With contemporary, human‐induced climate change at a crisis point, extreme weather events (e.g., cyclones, heatwaves, floods) are becoming more frequent, intense, and difficult to predict. These events can wreak rapid and significant changes on ecosystems; thus, it is imperative to understand how wildlife communities respond to ...
