Abstract
There was a group of A. h. brunneus in an isolated forest fragment of 21 ha, with a density of 39 individuals/ km2 (95% CI = 21.3-72.9). This is the smallest area where high density is estimated to Ateles. The group of A. h. brunneus was composed of nine individuals, being smaller than that recorded in other investigations. Ateles has a fission-fusion social system, where groups are divided into subgroups. The average size group of four individuals per subgroup was not different from that reported in other investigations. The ratios male-female and female-immature were 1:0.67 and 1:2 respectively. ©SAREM, 2010.
