Mitochondrial sequences show diverse evolutionary histories of African hominoids.
The results are relevant to the origin of zoonotic diseases, including HIV-1, and call into question some aspects of the current taxonomic treatment and conservation management of gorillas and chimpanzees. Expand
Nest building behavior in the great apes: the great leap forward?
INTRODUCTION Over decades apes have served as either referential or conceptual models in attempts to reconstruct the path of human evolution (Ghiglieri, 1987; Wrangham, 1987). In the search forExpand
Behavioural Diversity in Chimpanzees and Bonobos
This work focuses on the study of reproduction and sexual behaviour in two chimpanzee populations: a comparison of Gombe (Tanzania) and Budongo (Uganda), and the evolutionary genetics and molecular ecology of chimpanzees and bonobos. Expand
Mothers matter! Maternal support, dominance status and mating success in male bonobos (Pan paniscus)
Mating success determinants in male bonobos are evaluated using data from nine male individuals from a wild population and results reveal a steep, linear male dominance hierarchy and a positive correlation between dominance status and mating success. Expand
Intracommunity relationships, dispersal pattern and paternity success in a wild living community of Bonobos (Pan paniscus) determined from DNA analysis of faecal samples
It is demonstrated that faecal samples can be a useful source for the determination of kinship in a whole community and support previous inferences on female dispersal and male philopatry. Expand
Culture in Bonobos? Between‐Species and Within‐Species Variation in Behavior1
Long-term studies on wild chimpanzees (Pan troglodytes) conducted over the past four decades have revealed extensive behavioral variation within and between local populations (McGrew 1983, Nishida etExpand
Use and function of genital contacts among female bonobos
It is suggested that genital contacts can be used to investigate both quality and dynamics of dyadic social relationships among female bonobos, and shown rank-related asymmetries in initiation and performance of genital contacts supporting the social status hypothesis. Expand
Exploring the contribution and significance of animal protein in the diet of bonobos by stable isotope ratio analysis of hair
The isotopic data indicate that the contribution of fauna to bonobo diet is marginal and that plant food is the dietary protein source and that dominance status within the group of males was positive and there was a positive correlation between dominance status and δ15N. Expand
Dynamics in social organization of bonobos (Pan paniscus)
Recently, the behavioural contrasts between the two Pan species have been questioned for various reasons, including scarcity of information from wild bonobos, and the failure to compare data from wild chimpanzees with what is known from studies of captive bonobos. Expand
Intra- and inter-sexual aggression by bonobos in the context of mating
Previous work on bonobos (Pan paniscus) has focused on the role of aggression in the context of conflict resolution in captive groups. This study investigates events of aggressive behaviour of wildExpand
