Primates, 2020 Chimpanzee societies generally show male philopatry and female dispersal. However, demographic data on wild chimpanzee societies from long-term study sites have revealed that some females give birth in their natal group (i.e., “remaining females”). Here, we report two remaining females in the M group in Mahale, Tanzania, and compare their cases with ...

Group dominance increases territory size and reduces neighbour pressure in wild chimpanzees [PDF]
Royal Society Open Science, 2020 Territorial social species, including humans, compete between groups over key resources. This between-group competition has evolutionary implications on adaptations like in-group cooperation even with non-kin.

Analysis of chimpanzee history based on genome sequence alignments. [PDF]
PLoS Genetics, 2008 Population geneticists often study small numbers of carefully chosen loci, but it has become possible to obtain orders of magnitude for more data from overlaps of genome sequences.

Comparing Predictors and Outcomes of Higher Allostatic Load across Zoo-Housed African Great Apes
Journal of Zoological and Botanical Gardens, 2023 Stressors over the lifespan can contribute to physiological dysregulation, or allostatic load. Allostatic load has been studied in humans using allostatic load indices (ALIs) for over 25 years, but the same methods are rarely applied to other species. We

Signs of mood and anxiety disorders in chimpanzees.
PLoS ONE, 2011 BackgroundIn humans, traumatic experiences are sometimes followed by psychiatric disorders. In chimpanzees, studies have demonstrated an association between traumatic events and the emergence of behavioral disturbances resembling posttraumatic stress ...

Evaluation of IL-28B polymorphisms and serum IP-10 in hepatitis C infected chimpanzees.
PLoS ONE, 2012 In humans, clearance of hepatitis C virus (HCV) infection is associated with genetic variation near the IL-28B gene and the induction of interferon-stimulated genes, like IP-10. Also in chimpanzees spontaneous clearance of HCV is observed.
