Skeletal and dental growth and development in chimpanzees of the Taı̈ National Park, Côte D’Ivoire

Non-invasive testing reveals a high prevalence of simian T-lymphotropic virus type 1 antibodies in wild adult chimpanzees of the Taı̈ National Park, Côte d’Ivoire

Received 23 February 2004 Accepted 12 July 2004 Little information is available on the prevalence of retrovirus infections in populations of non-human primates living in their natural habitats. To gain such information, methods were developed to detect antibodies to simian T-lymphotropic virus type 1 (STLV-1) in urine from wild chimpanzees. Samples from more than 74 chimpanzees living in three ...

Morphological Variation in Adult Chimpanzees (Pan troglodytes verus) of the Taı̈ National Park, Côte D’Ivoire

Twenty five adult chimpanzee skeletons (Pan troglodytes verus) of known age and sex (15 females, 10 males) from a long-term study site in Taı̈ National Park, Cote d’Ivoire present new data on variation. These skeletons provide a rare opportunity to measure the cranium and postcranium from the same individuals. We compare measurements and indices of the Taı̈ sample with those of relatively complet...

Chimpanzee movement patterns and social ecology in the Taï National Park, Côte d’Ivoire

Stable isotope canopy effects for sympatric monkeys at Taı̈ Forest, Côte d’Ivoire

This study tests the hypothesis that vertical habitat preferences of different monkey species inhabiting closed canopy rainforest are reflected in oxygen isotopes. We sampled bone from seven sympatric cercopithecid species in the Taı̈ forest, Côte d’Ivoire, where long-term study has established taxonspecific patterns of habitat use and diet. Modern rib samples (n 1⁄4 34) were examined for oxygen...

A human reproductive approach to the study of infertility in chimpanzees: An experience at Leon’s Zoological Park, Mexico

Great apes are mammals close to humans in their genetic, behavioral, social and evolutionary characteristics and new genomic information is revolutionizing our understanding of evolution in primates. However, all these species are endangered. While there are many global programs to protect these species, the International Union for Conservation of Nature (IUCN) projects that in a near future th...
