Unlike most chimpanzee habitats, the Toro-Semliki Wildlife Reserve is a diverse mosaic of grassland, woodland, and swamp. The most ideal chimpanzee habitat lies in two narrow corridors of riverine forest that stretch across this mosaic. I collected DNA samples from the chimpanzees that live there to better understand through DNA analysis how corridors facilitate or constrain chimpanzee gene flow. The results of this study will inform conservation strategies across east and central Africa.
