Subspecies composition and founder contribution of the captive U.S. chimpanzee (Pan troglodytes) population
Article Abstract:
The subspecies (Pan troglodytes, P.t. troglodytes, P.t. schweinfurthii, P.t. vellerosus) composition of chimpanzee founders was studied using genetic criterion. It was observed that troglodytes/ schweinfurthii reduced in captivity, vellerosus increased due to prolific breeding by single male and reproductive variance resulted in uneven representation among male P.t verus founders, no increase in mortality between subspecies interbreeding indicating a lack of outbreeding depression.

Reproductive endocrinology of wild female chimpanzees (Pan troglodytes schweinfurthii): Methodological considerations and the role of hormones in sex and conception
Article Abstract:
Some of the issues related to sample storage and assay reliability were evaluated, and were used to investigate the significance of ovarian hormone levels in terms of conception success and sexual behavior. Comparison across cycles confirmed the hypothesis that higher ovarian steroid levels are associated with an increased probability of conception and female that did conceive with relatively low hormone levels had poor reproductive outcomes.

Genotyping aids field study of unhabituated wild chimpanzees
Article Abstract:
Data of habituation of the animals is required to conduct a study on wild chimpanzees, which takes years to collect. The aim of the study is to show how genotyping of wild chimpanzees by noninvasive means can enable the tracking of individuals through sex determination and identification of related dyads.
