Abstract
Abstract The purpose of this study was to assess the relative abundance and activity patterns of terrestrial carnivorous mammals living in San Pablo de Valdés Wildlife Reserve, which is located in Península Valdés (PV), Chubut province, Argentina. To this end, camera traps were placed in different plant communities of this reserve and they were used from January 2015 to December 2016. A total of 256 independent events, with a sampling effort of 1811 camera nights, were obtained. The following species were identified in order of relative abundance: Conepatus chinga, Lycalopex gymnocercus, Leopardus geoffroyi, Puma concolor, and Leopardus colocolo, and the activity patterns of the first three were estimated. Those of P. concolor and L. colocolo could not be estimated as insufficient independent events were obtained. Our results show a cathemeral activity pattern in C. chinga and L. geoffroyi and a more nocturnal pattern in L. gymnocercus. Our results highlight the need to expand the sampling area to obtain further details on the behavioral patterns and population parameters of the carnivores identified. Knowledge of ecological issues, such as relative abundance and activity patterns of carnivorous mammals, is imperative to formulate monitoring and conservation programs.
