Medium-sized and large mammals of the Floresta da Cicuta Area of Relevant Ecological Interest, a protected area in southeastern Brazil

The Atlantic Forest is one of the most biodiverse biomes in the world and has been severely degraded and fragmented, with the extirpation of most medium-sized and large vertebrates from the forest remnants. Here we present the results of a survey of medium-sized and large mammals in an area of protected seasonal semideciduous forest, the Floresta da Cicuta Area of Relevant Ecological Interest (ARIE-FC), Rio de Janeiro, Brazil, part the Atlantic Forest biome. We used camera traps (2,257 camera days) and direct observations over a 23-month period. We recorded 19 species (including two domestic species), seven of which are classified as at-risk, such as Leopardus guttulus (Hensel, 1872), Sylvilagus tapetillus Thomas, 1913, Alouatta clamitans Cabrera, 1940, and Chrysocyon brachyurus (Illiger, 1815). A diverse terrestrial mammal assemblage in the ARIE-FC reinforces the importance of small forest fragments for the conservation of biodiversity in human-modified landscapes of the Brazilian Atlantic Forest
