Shared habitats between humans and other animals are increasing in the twenty-first century, which may require behavioral flexibility from animal species to adjust to these new environments. We evaluated the effects of anthropogenic pressure on Geoffroy’s spider monkeys (Ateles geoffroyi) in a low-impact tourism area. Over the course of 18 months,...

El uso de las cámaras trampa (CT) en la investigación de fauna silvestre puede generar conclusiones sesgadas cuando la detectabilidad imperfecta de especies no es considerada. Herramientas analíticas como los modelos de ocupación permiten estimar simultáneamente parámetros ecológicos corregidos por la probabilidad de detección. Sin embargo, es nece...

Patch size is considered a major driver of species diversity in fragmented landscapes. Yet, assemblages of forest-dependent species, such as tropical arboreal mammals, can also depend on vegetation characteristics within the patch, i.e. patch quality. To test this, we assessed the influence of patch size and quality (measured through six attributes...

Activity patterns are related to the way in which the basic needs of individuals of a species are met. The white-tailed deer Odocoileus virginianus is considered a crepuscular species; however its activity patterns can vary with sex, age, reproductive physiology, the quantity and availability of forage, and other factors. Little is known about the...
