  abstract = {{C}omplex ecological pressures affect the social dynamics of many primate species, but it is unclear how they affect primate speciation. {M}olecular tools are often used to answer questions about the evolutionary histories and social systems of primates. {M}itochondrial {DNA} (mt{DNA}), in particular, is frequently used to answer many of these questions, but because it is passed from mothers to offspring it reveals only the histories of females. {I}n many species, including chimpanzees, females generally disperse from their natal groups while males are philopatric, and thus differences in dispersal patterns likely leave different signatures in the genome. {W}e previously analyzed samples from 187 unrelated male and female chimpanzees in {N}igeria and {C}ameroon using 21 autosomal microsatellites and mt{DNA} sequences. {H}ere, we examine the contributions of males and females in shaping the genetic history of these chimpanzees by genotyping a subset of 56 males at 12 {Y}-chromosome microsatellites. {W}e found that {Y}-chromosome population structure differed from the results of analysis of mt{DNA} haplotypes. {T}he results also revealed that males in rainforest habitats ({G}uinean and {C}ongolian rainforests) are more closely related to one another than those inhabiting the savanna-woodland mosaic ecotone in central {C}ameroon. {I}n contrast, the pattern of female relatedness did not differ across habitats. {W}e hypothesize that these differences in population structure and patterns of relatedness among males in different habitat types may be due to differences in the community dynamics of chimpanzees in the ecotone vs. rainforests, and that these factors contribute to making {C}ameroon an engine of diversification for chimpanzees. {B}roadly, these results demonstrate the importance of habitat variation in shaping social systems, population genetics, and primate speciation.},
