In most group-living animals, a dominance hierarchy reduces the costs of competition for limited resources. Dominance ranks may reflect prior attributes, such as body size, related to fighting ability or history self-reinforcing effects winning and losing conflict (the winner-loser effect), both. As in sexually dimorphic species, where males are larger than females, assumed be dominant over females. effect, computational model DomWorld has shown that despite female’s lower initial ability,...
Habitats with spatial variation in food availability, predation risk, and hunting pressure allow us to study how animals resolve the trade-off between searching predator avoidance. We investigated influence of perceived risk on habitat use by a primate living under high pressure, yellow-breasted capuchin monkeys, Sapajus xanthosternos, at Una Biological Reserve (ReBio Una). hypothesized that occurring capuchins' home range would favor avoidance detriment for food. characterized set...
In the northern Atlantic Forest, hunting and habitat loss have eliminated most large mammals that disperse zoochoric fruits. Due to decrease in populations of seed dispersers, yellow-breasted capuchins (Sapajus xanthosternos) are currently one largest arboreal fruit-eating region. During 26 months, we followed 14-25 aiming (1) present data on their dietary ecology, (2) verify conservation status plants diet, (3) determine distance deposition based gut retention time. Capuchins showed a...
