Patterns of predation by chimpanzees on red colobus monkeys in Gombe National Park, 1982-1991.
Predatory patterns in wild chimpanzees are important evidence in the continuing debate about the role of hunting in the behavior of early hominids, and hunting showed a strong "binge" tendency from 1982 to 1991.
Averting biodiversity collapse in tropical forest protected areas
These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.
The Social Behavior of Chimpanzees and Bonobos: Empirical Evidence and Shifting Assumptions1
As our closest living relatives, chimpanzees and bonobos have been widely used as models of the behavior of early hominids. In recent years, as information on the social behavior and ecology of
The Capped Langur in Bangladesh: Behavioral Ecology and Reproductive Tactics
Study animal, study site and methods ranging behaviour activity patterns feeding ecology inter-group social behaviour population dynamics, dispersal and inter-group relations.
Evidence from Gombe National Park, Tanzania is presented showing that the social factors that most strongly influence the decision to hunt red colobus monkeys are the presence of female chimpanzees with anogenital sexual swellings in the foraging party, the number of adult and adolescent males in the party, and the total size of theforaging party.
Behavioral Ecology of Sympatric Chimpanzees and Gorillas in Bwindi Impenetrable National Park, Uganda: Diet
It is found that chimpanzee and gorilla diets are seasonally similar, but diverge during lean seasons, and three factors—seasonal consumption of fibrous foods by gorillas, interspecific differences in preferred fruit species, and meat consumption by chimpanzees—contributed to dietary divergence.
The influence of chimpanzee predation on group size and anti-predator behaviour in red colobus monkeys
Group size and anti-predator behaviour of red colobus monkeys, Colobus badius tephrosceles, were studied in relation to predation by chimpanzees, Pan troglodytes schweinfurthii, in Gombe National Park, Tanzania.

Intergroup Aggression in Chimpanzees and Humans [and Comments and Replies]
The occurrence of fatal attacks during intergroup encounters among chimpanzees suggests that certain aspects of chimpanzee and human intergroup aggression may be explicable in similar ways. This
