Movement decisions reflect compromised statewide connectivity for mountain lions in California

Frontiers in Ecology and the Environment, Volume 24, Issue 2, March 2026.
Human‐induced habitat fragmentation threatens connectivity for populations of wide‐ranging species by compromising long‐distance dispersal. We evaluated movement‐based resource selection of dispersing mountain lions (Puma concolor) to identify specific landscape conditions influencing movement decisions and connectivity between populations across the ...

When Calves Get Vulnerable, Ocelots (Leopardus pardalis) Get Bold: A Camera Trap Record of Opportunistic Foraging in a Fragmented Landscape

Biotropica, Volume 58, Issue 2, March 2026.
We report the first confirmed record of an ocelot (Leopardus pardalis) dragging a newborn calf in a degraded forest fragment of southeastern Brazil. Using camera trap records, we reveal an opportunistic foraging event involving a vulnerable domestic prey within a highly fragmented landscape.

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

No Pedigree, No Problem: Genomic Inbreeding Tracks Genetic Rescue With High Resolution

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT With increasing habitat fragmentation and population isolation, inbreeding becomes a pressing concern for the persistence of wildlife populations. Detailed inbreeding monitoring is crucial for assessing extinction risk and evaluating the effectiveness of conservation management strategies.

Scat DNA Applications for Low‐Density Carnivore Survey: Techniques, Efficiency and Future Directions

Mammal Review, Volume 56, Issue 1, March 2026.
We reviewed 338 studies encompassing mostly Felidae, Canidae and Mustelidae species throughout the world, confirming scat DNA as a reliable genetic source for many applications. The findings here offer guidance for future studies on low‐density carnivores, helping to design cost‐effective research and improving data quality for conservation efforts ...

Exotic deer in southern Latin America: what do we know about impacts on native deer and on ecosystems? [PDF]

, 2018
A recent review on exotic cervids concluded that deer introduced to Patagonia impacted habitat and native huemul deer Hippocamelus bisulcus. I evaluate these assertions and amend information about this South American case study.

The American Black Bear (Ursus americanus) as an Apex Predator: Investigating the Ecological Role of the World's Most Abundant Large Carnivore

Mammal Review, Volume 56, Issue 1, March 2026.
Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.
