Chimpanzee literature from Uganda predominately focuses on the country's larger protected areas, so chimpanzees traveling through smaller, unprotected areas outside park boundaries are often overlooked. However, connectivity and fragment constraints deserve more attention because the exponential growth of human populations (in Uganda especially) is forcing more and more prime habitats farther apart and into smaller plots. The open-mosaic habitat of Toro-Semliki Wildlife Reserve stands in stark contrast to the classically studied, closed-forest chimpanzee habitats. The habitat there is unique in that most of the chimpanzee food and nest sites are limited to narrow corridors of riverine forest, surrounded by wide expanses of open grassland and patches of grassy woodland. Thus, chimpanzees have already adapted to a life constrained by rainforest corridors, much like those proposed to connect chimpanzee populations across east and central Africa. I employed noninvasive genetic sampling to examine how this unique habitat constrains chimpanzee population size, community divisions, connectivity to other protected areas, and health. Genetic capture-mark-recapture methods suggest a larger population of chimpanzees than was anticipated. To date, 39 unique individuals were genetically sampled, and recapture estimates suggest a likely population size of ∼183 individuals. Networks of association and geographic location of samples suggest that all chimpanzees sampled belong to a single, large community. Additionally, mtDNA sequences, when compared to those published from chimpanzees in other protected areas, suggest healthy, consistent levels of connectivity with other chimpanzee populations. This dissertation also presents the first known case of testicular dysgenesis syndrome (TDS) in wild chimpanzees. Two of the males identified likely have cryptorchidism, while another likely has a testicular hydrocele. The causes and consequences of TDS in wild primates are discussed, and future research plans are proposed.
