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 ...

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.

Jaguar Density at the Northeastern Limit of Its Distribution in Mexico

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study presents the first estimate of jaguar density in northeastern Mexico using a spatial capture–recapture model with random thinning, which incorporates both identified and unidentified camera trap detections. Conducted over 91 days with 104 cameras, the model yielded a density of 1.29 individuals per 100 km2 in the El Cielo–Sierra de Tamalave ...

Hematology and Serum Chemistry of Free-ranging Jaguars (Panthera onca) [PDF]

Journal of Wildlife Diseases, 2012
We collected and analyzed blood samples from 12 free-ranging jaguars (Panthera onca). Clinical examinations, hematology, and serum chemistry indicate the jaguars were in good overall health. Results may help as values for free-ranging jaguars under the same handling conditions.

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.
