Diurnal Human Activity and Introduced Species Affect Occurrence of Carnivores in a Human-Dominated Landscape

摘要: Diurnal human activity and domestic dogs in agro-forestry mosaics should theoretically modify the diurnal habitat use patterns of native carnivores, with these effects being scale-dependent. We combined intensive camera trapping data Bayesian occurrence probability models to evaluate both nocturnal space by carnivores a mosaic land-use types southern Chile. A total eight species were recorded, including human-introduced dogs. During day most frequently detected culpeo fox cougar. Conversely, during night, kodkod chilla species. The best supported showed that responded differently landscape attributes depending on time as well spatial scale attributes. positive effect forest cover at 250m 500 m radius buffers was stronger night for Darwin's Road density negatively affected Darwin´s fox, whereas 500m roads had negative foxes cougars. road dog evidenced day.
