Savanna Chimpanzees (Pan Troglodytes Verus) As A Referential Model For The Evolution Of Habitual Bipedalism In Hominids, Christine Alexandra Tourkakis Jan 2009

Savanna Chimpanzees (Pan Troglodytes Verus) As A Referential Model For The Evolution Of Habitual Bipedalism In Hominids, Christine Alexandra Tourkakis

Graduate Theses and Dissertations

Observations of the bipedal behavior of wild savanna chimpanzees (Pan troglodytes verus) can provide insight into the evolution of habitual bipedalism in early hominids. This study provides data on the bipedal behavior of eight adult male chimpanzees at the Fongoli field site in southeastern Senegal. Data were collected during transition months at the end of the dry season and beginning of the wet season. Focal instantaneous data on positional and locomotor behavior indicate that bipedalism in Fongoli chimpanzees is a rare, infrequent behavior, accounting for only 2.3% of all positional and locomotor behaviors. Focal all-occurrences data provides a more ...


Behavioral Ecology Of Savanna Chimpanzees (Pan Troglodytes Verus) With Respect To Insectivory At Fongoli, Senegal, Stephanie L. Bogart Jan 2009

Behavioral Ecology Of Savanna Chimpanzees (Pan Troglodytes Verus) With Respect To Insectivory At Fongoli, Senegal, Stephanie L. Bogart

Graduate Theses and Dissertations

In this dissertation I examine the behavioral ecology of savanna chimpanzees in Senegal. I test hypotheses related to the effects of the environment on the diet of the chimpanzees at Fongoli, concentrating on their insectivory specifically. Fongoli is the hottest and driest site in which chimpanzees have been habituated for observational data collection. Grassland habitats (68%) dominate, characterizing the site as an open savanna mosaic, which is interspersed with woodland and small patches of closed forests. The environment at Fongoli presents a setting similar to that of Plio-Pleistocene hominans (Bobe & Behrensmeyer 2004, Bromage & Schrenk 1995, Cerling 1992, Reed 1997) and ...
