Exchange, affiliation, and protective interventions in semifree-ranging brown Capuchin monkeys (Cebus apella)

Article Abstract:

The patterns of coalitionary behavior observed in a semifree-ranging group of Cebus apella is presented and the effects of kinship, spatial proximity and rank on behavior are explored. Kinship does not influence coalitionary behavior, although individuals tend to help those in close proximity, but rank is most influential on behavior and most coalitions are protective interventions involving immatures, although there is evidence of knowledge of harmony among individuals.

Advantage of dichromats over trichromats in discrimination of color-camouflaged stimuli in nonhuman primates

Article Abstract:

The performance of dichromats and trichromats in discrimination of color-camouflaged stimuli in nonhuman primates is compared. The findings demonstrate that dichromatic nonhuman primates possess a superior visual ability than dichromate's to discriminate color-camouflaged stimuli, which might confer selective advantages with respect to the detection of cryptic foods and predators.

Demonstration of a genotype-phenotype correlation in the polymorphic color vision of a non-callitrichine new world monkeys, capuchin (Cebus apella)

Article Abstract:

Genotype and phenotype color vision of brown capuchin monkeys, a representative non-callitrichine model animal for physiology and behavior are evaluated. Results demonstrate the mutual consistency between genotype and phenotype color vision and provide a solid genetic basis for the ecology and evolution of color vision investigation.
