Colicodendron scabridum, commonly known as “sapote”, is one of the most common woody species in seasonally dry neotropical forests, and an important food for numerous animals. We investigated sapote’s reproductive phenology and evaluated its re

To address biodiversity decline in the era of big data, replicable methods of data processing are needed. Automated methods of individual identification (ID) via computer vision are valuable in conservation research and wildlife management. Rapid and

Natal dens are critical for reproduction in bears, yet we know virtually nothing of Andean bear (Tremarctos ornatus) denning ecology, nor whether female Andean bears select dens or den sites with specific characteristics. We analyzed data from 2008 t

The Andean bear alopecia syndrome is a progressive and chronic condition documented in ex situ populations. Recent advances focus on treating symptoms, not preventing future cases. We therefore explored the epidemiology of this syndrome through an an

It is often challenging to use invasive methods of individual animal identification for population estimation, demographic analyses, and other ecological and behavioral analyses focused on individual-level processes. Recent improvements in camera tra

Inbreeding can have negative consequences on population and individual fitness, which could be counteracted by inbreeding avoidance mechanisms. However, the inbreeding risk and inbreeding avoidance mechanisms in endangered species are less studied. T

To advance our knowledge on the rubbing behavior of Andean bears (Tremarctos ornatus), we assessed characteristics of their rub-trees in the Peruvian tropical dry forest, where water is a rare and critical resource. We registered characteristics of r
