The feeding behaviour of a group of free-ranging muriquis (Brachyteles arachnoides) was monitored in the 380 km2 Carlos Botelho State Park (PECB), between February 1992 and November 1993. Scan sample data indicated that 59.1% of feeding time was devoted to fruit, 33.2% to leaves, 4.1% to flowers, and 3.6% to other items (twigs, stem and bark). Little seasonal variation was recorded. These results contrast with those of all previous studies of Brachyteles, in which the consumption of leaves was generally double that of fruit. One key difference in comparison with previous studies is that the PECB is part of the largest remaining continuous area of primary Atlantic forest, in the Serra do Mar coastal range. Such intraspecific differences in ecology may have important implications for the conservation of the species.

Organizações da sociedade civil pedem uma medida imediata em defesa do Cerrado a ser tomada pelas empresas que compram soja e carne desse bioma, assim como os investidores que atuam nesses setores, no sentido de adotarem políticas e compromissos eficazes para eliminar o desmatamento e desvincular suas cadeias produtivas de áreas naturais recentemente convertidas.
