Abstract

We evaluated puma (Puma concolor) and culpeo fox (Pseudalopex culpaeus smithersi) occurrence in relation to a national park where livestock was reduced and hunting banned, and in relation to human presence and landscape features. In the high mountains of central Argentina puma signs were about 3.5 times less frequent than culpeo signs. Puma and culpeo signs were 33 and 19 times, respectively, more abundant within than outside the park. Puma signs increased with distance to settlements within the park but no trend was detected outside the park where signs were scarce. Culpeos were abundant all throughout the park with no relation with distance to settlements while outside the park signs increased with distance from settlements. Rock outcrops had a positive effect on pumas, which used this habitat frequently, and negative effect on culpeos, whose presence decreased slightly at sites with the highest proportion of rock outcrops inside the park and sharply at sites with presence of rock outcrops outside the park. We conclude that top carnivores were positively affected by the park creation and encourage the creation of more protected areas with connectivity in the region to better assure the long-term conservation of top predators.

► We evaluated top carnivore occurrence in relation to different landscape features. ► Puma was more abundant inside a protected area but less frequent than culpeo fox. ► In areas away from the human settlements the occurrence of both carnivores was higher. ► Rock outcrops are important resource to hide from any threat used more frequently for pumas than culpeos. ► Unprotected sites and near human settlements are risk areas or barriers to top carnivores.
