Dominance style of female white-faced capuchins.
Dominance style, the level of tolerance displayed by dominant individuals toward subordinate ones, is exhibited along a continuum from despotic to relaxed. It is a useful concept to describe the nature of dominance relationships in macaque species and it bridges among multiple features of dominance hierarchies, aggression, kinship and conflict resolution. Capuchins share many behavioral similar...
متن کاملEcology and contaminant exposure of Lake Calumet Black-crowned Night Herons: Population Levels and Nesting Ecology Final Report
We examined a suite of organic and inorganic analytes in a sample of Black-crowned NightHeron (BCNH) embryos collected from a colony located adjacent to Lake Calumet in southeastern Chicago, Illinois, in 2002. Our objectives were to determine whether embryos from the Lake Calumet colony had greater exposure to environmental contaminants, when compared to samples from other contemporary populati...
متن کاملSocial facilitation of fur rubbing behavior in white-faced capuchins.
In their natural environment, capuchins select certain plants, containing secondary compounds with bactericide, insecticide or fungicide properties, to rub their pelage energetically (i.e. fur rubbing). Fur rubbing can be performed in solitary, or collectively in subgroups of variable size and composition, and most of the time fur rubbing happens in synchrony with other group members. The aim o...
متن کاملCollective decision-making in white-faced capuchin monkeys.
In group-living animals, collective movements are a widespread phenomenon and occur through consensus decision. When one animal proposes a direction for group movement, the others decide to follow or not and hence take part in the decision-making process. This paper examines the temporal spread of individual responses after the departure of a first individual (the initiator) in a semi-free rang...
متن کاملEffect of color vision phenotype on the foraging of wild white-faced capuchins, Cebus capucinus
New World monkeys exhibit a color vision polymorphism. It results from allelic variation of the single-locus middle-to-long wavelength opsin gene on the X chromosome. Females that are heterozygous for the gene possess trichromatic vision. All other individuals possess dichromatic vision. The prevailing hypothesis for the maintenance of the color vision polymorphism is through a consistent fitne...
