This work examines patches of Atlantic forests
in Minas Gerais State where woolly spider monkeys
(Brachyteles hypoxanthus) are inhabitants in order to
understand the effects of forest structure, diversity, and
succession in B. hypoxanthus abundance. This study was
carried out in three reserves: Rio Doce State Park
(PERD), Mata do Sossego (Sossego), and Serra do
Brigadeiro State Park (PESB). Structural studies were
carried out by means of point-centered quarter samples
in areas used by woolly spider monkeys. Evenness was
lower in PERD than in the other two communities. By
means of successional functional groups analysis and
diametric structure, the PERD forest sample was shown
to be in the later, and PESB forest sample in the earlier,
stages of secondary succession. We found that tree
species evenness and structural traits driven by succession
were important factors in determining spider
monkey abundance patterns. The PERD forest sample
had lower evenness and had lower density of woolly
spider monkeys than the Sossego forest sample. The
lowest density of these primates was in the PESB forest
sample, the earlier successional stage of secondary succession
of this study.
