Activity patterns and temporal overlap between native and exotic carnivores in southern remnants of the tumbesian dry forest in Perú
The tumbesian dry forest is an endangered ecosystem located in northwestern Perú. The last remnants on its southern distribution are located in the region of La Libertad. As in other ecosystems, the presence of domestic dogs and cats can have a negative effect on native wild carnivores; however, this problem is rarely studied in Perú. In this study we assess the activity patterns and temporal overlap between domestic and wild carnivores, by photo-trapping, within tumbesian dry forest remnant located in San José-Pacasmayo (La Libertad). During August 2020 to February 2021, we registered 452 independent carnivore s events and a sampling effort of 1380 trap nights. Our results revealed that the domestic cat (Felis silvestris catus), the domestic dog (Canis lupus familiaris), and the Sechuran fox (Lycalopex sechurae) presented a catameral activity, while the pampas cat (Leopardus garleppi) and the striped hog-nosed skunk (Conepatus semistriatus) presented a mostly nocturnal activity. The pampas cat and the domestic cat presented a high temporal overlap; the Sechuran fox and both domestic carnivores presented a moderate overlap; the striped hog nosed skunk and the domestic cat obtained moderate temporal overlap, and the striped hog nosed skunk and the domestic cat showed a low temporal overlap. Our results suggest that the pampas cat, the striped hog nosed skunk and the Sechuran fox are susceptible to interacting with domestic carnivores.
