The Chimpanzees of the Tai Forest : Behavioural Ecology and Evolution
This study highlights the importance of understanding the social structure of the Tai chimpanzee community and the relationships within the community to understand the behaviour of chimpanzees in the wild.

Forest chimpanzees have a more specialized prey image, intentionally search for more adult prey, and hunt in larger groups and with a more elaborate cooperative level than savanna-woodlands chimpanzees, and tend to share meat more actively and more frequently.
Quantitative polymerase chain reaction analysis of DNA from noninvasive samples for accurate microsatellite genotyping of wild chimpanzees (Pan troglodytes verus)
An assay designed to measure the amount of amplifiable nuclear DNA in low DNA concentration extracts from noninvasive samples is described and a new efficient approach for accurate microsatellite genotyping is formulated.
Microsatellite scoring errors associated with noninvasive genotyping based on nuclear DNA amplified from shed hair
It is found that genotypes based on single PCR amplifications of microsatellite loci from single shed hair have a high error rate and allelic dropout becomes a problem when the DNA concentration falls below 0.05 ng/10 μL in the template as it can with shed hair, and extracts from faeces and masticated plant matter.
CHARTING CULTURAL VARIATION IN CHIMPANZEES
Cultural variation among chimpanzee communities or unit-groups at nine long-term study sites was charted through a systematic, collaborative procedure in which the directors of the sites first agreed…
Tool use and tool making in wild chimpanzees.
Factors involved in the acquisition and the benefit of tool use are discussed along with factors affecting the frequency and complexity of tool making in chimpanzees.

Abstract Abstract. A model for the evolution of cooperation shows that two conditions are necessary for cooperation to be stable: a hunting success rate that is low for single hunters and increases…
Renewed interest in fission‐fusion dynamics is due to the recognition that such dynamics may create unique challenges for social interaction and distinctive selective pressures acting on underlying…

A synthetic life table for free-living chimpanzees, derived from data collected in five study populations, suggests the low mortality rate of human foragers relative to chimpanzees in the early adult years may partially explain why humans have evolved to senesce later than chimpanzees, and have a longer juvenile period.

There was a small negative correlation between temperature at time of collection and the amount of DNA obtained, but significantly higher amounts of DNA were obtained using a novel protocol that combines a short period of storage in ethanol with subsequent desiccation using silica.
