Patterns of coexistence between two mesocarnivores in northern Patagonia in the presence of invasive hares and anthropogenic disturbance

摘要: We analysed coexistence patterns between two mesocarnivores, Geoffroy's cat (Leopardus geoffroyi: Felidae) and culpeo fox (Pseudalopex culpaeus: Canidae), in northern Patagonia, Argentina. examined spatial distribution influenced by land cover, anthropogenic disturbance invasive hare presence, temporal activity dietary composition. If competitive exclusion accounts for carnivore this system, we predicted segregation would occur one or more of these aspects as a mechanism coexistence. performed camera trapping Nahuel Huapi National Park, from February to May 2012 January April 2013. Using detections, with co-occupancy modelling fitting kernel density estimates measuring overlap. meta-analysis using available literature discriminant function analysis diet categories species. observed high overlap cats foxes. found no evidence relation cover occupancy, disturbance, occurrence patterns. Though both species consumed predominantly small medium mammals, birds, reptiles amphibians, foxes large carrion plant material; carnivores Patagonian protected area appears be facilitated segregation.
