Our results reinforce the contribution of fragment size to maintain biodiversity within highly degraded habitats. Twelve models were plausible, and three were validated, two for Sapajus nigritus (Area and Area+Visibility) and one for Callicebus nigrifrons (Area+Matrix). Aiming at validating our results, we applied the plausible models to another region (20 fragments at the neighboring municipality of Poço Fundo, Brazil). We selected the best models through Akaike Selection Criterion. We classified the landscape and evaluated the metrics through predictive models of occurrence. Employing playback, we verified the presence of Callicebus nigrifrons, Callithrix aurita and Sapajus nigritus at 45 forest fragments around the municipality of Alfenas, Brazil. We evaluated if fragment size, isolation and visibility and matrix permeability are important for explaining the occurrence of three Neotropical primate species. ![]() ![]() Thus, landscape changes that negatively interfere with primate population dynamic affect the structure, composition, and ultimately the viability of the whole community. Furthermore, primates are involved in complex ecological process. ![]() Being primarily arboreal, Neotropical primates are generally sensitive to fragmentation effects. ![]() Remaining fragments are mostly small, isolated and showing poor quality. Forest fragmentation and habitat loss are among the major current extinction causes.
