Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.

Spatial Ecology and Habitat Selection by Jaguars and Pumas in a Protected Area in the Atlantic Forest of Brazil

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Understanding animal distribution is crucial for elucidating natural history, population dynamics, and inter‐ and intraspecific interactions. This knowledge informs the planning and evaluation of management and conservation strategies, particularly for sympatric, scarce, and threatened species such as jaguars (Panthera onca) and pumas (Puma ...

Trait‐filtered responses of mammal communities to land use change in a Neotropical dry forest

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Land use change alters forest ecosystems by reducing habitat amount and often increasing fragmentation, but the relative importance of these drivers for community dynamics remains debated. It is also unclear whether functional traits consistently predict species' responses to forest change, particularly in tropical dry forests.
