摘要: Abstract In the absence of information on species in decline with contracting ranges, management should emphasize remaining populations and protection their habitats. Threatened by anthropogenic pressure including habitat degradation loss, sloth bears (Melursus ursinus) India have become limited range, habitat, population size. We identified ecological determinants occurrence within an occupancy framework to evaluate suitability non-protected regions (with bears) northeastern Karnataka, India. employed a systematic sampling methodology yield presence–absence data examine priori hypotheses that affected occupancy. These covariates were broadly classified as or factors. Mean number termite mounds trees positively influenced bear occupancy, grazing expounded mean livestock dung it negatively. Also, percentage shrub coverage had no impact in...
