Fruit availability, chimpanzee diet, and grouping patterns on Rubondo Island, Tanzania

Article Abstract:

The seasonal patterns of fruit availability, dietary quality and group size in the descendant of chimpanzee population on Rubondo Island, Tanzania, are examined. The results have contrasted with the evidence from several endemic chimpanzee sites, indicating that Rubondo chimpanzees might have access to abundant and high-quality foods throughout the year.

Article Abstract:

Common marmosets (Callithrix jacchus) demonstrate significant variation in reproductive output on both a yearly and lifetime basis in comparison to other anthropoid primates. It is found that maternal age, maternal condition and dam survivorship are related to reproductive output, however, these reports are not in agreement and are far from conclusive.
