Arboreal Camera Trap-based Insights into the Activity, Resource Use, and Demography of Black Lion Tamarins (Leontopithecus chrysopygus) and Sympatric Mammals in Atlantic Forest Fragments

Abstract Wildlife monitoring is essential for guiding biodiversity conservation strategies, particularly in fragmented ecosystems under intense anthropogenic pressure. While noninvasive methods, such as camera traps, are widely used for terrestrial species, their application in other forest strata is underexplored despite its potential for studying elusive and nocturnal arboreal mammals. We aim to evaluate whether arboreal camera trapping is a relevant tool for monitoring the endangered black li
