PELAYO-MARTINEZ, Jaime et al. Daily activity of threatened canopy mammals in a private protected natural area of tropical southeastern Mexico. Rev. Mex. Biodiv. [online]. 2023, vol.94, e944951.  Epub 14-Jun-2024. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2023.94.4951.

Private Conservation Areas (CPAs) are a complementary resource to support mammal conservation in tropical regions of the world. However, their small surface area can exert a differential influence on the species present in terms of behavior and affect their coexistence. During the 2016 rainy season, we investigated the daily activity patterns of canopy mammals in a 100 ha CPA in a rainforest. For this, 11 camera traps were placed in the trees, 15 m high. Sciurus deppei showed diurnal activity, Potos flavus around midnight, and Caluromys derbianus and Coendou mexicanus before and after midnight. Tamandua mexicana and Didelphis marsupialis were active throughout the night. Nocturnal mammals showed great overlap in their hours of activity. Overall, there were no differences in canopy mammal activity patterns in this APC compared to those reported in larger protected natural areas. The greatest number of records occurred in the tallest trees located in the best-preserved parts of the study area, suggesting the importance of APCs being forested for the conservation of canopy mammals.
