Theropithecus gelada is endemic to Ethiopia, mainly in the northern part of the Ethiopian plateau. Despite the relatively long-term research efforts on the population and behavioural ecology of geladas, and its conflict with humans in protected areas, these data are lacking in unprotected areas. Accordingly, this study was conducted to determine po...
