Population status of a nocturnal primate (the Philippine tarsier - Carlito syrichta, Linnaeus, 1758) in an agricultural area of Subayon, Bilar, Bohol.

The destruction of wildlife habitats due to the exponential growth of human population and its encroachment into wild areas is a major threat to many species around the world. In order to understand the effects of human disturbance on the Philippine tarsier (Carlito syrichta), we evaluated its population status by quantifying the species' population density in an agricultural habitat and assessed the degree of human disturbance in the area. We did the study in Subayon, Bilar, Bohol, where we surveyed 32 ha out of the total 115 ha of the village between April and June 2017.
