ABSTRACT
The mechanisms of ecological segregation involved in the coexistence between Neotropical felids are the key to support strategies for conservation. Due to their inconspicuous and elusive behavior, camera trapping constitute a strategic, non-invasive method to study these species. The present work aimed to evaluate the daily and seasonal activity patterns of four felid species: Leopardus guttulus (Hensel, 1872), L. pardalis (Linnaeus, 1758), L. wiedii (Schinz, 1821) and Puma concolor (Linnaeus, 1771), in the Papagaios-de-Altitude Private Protected Area, state of Santa Catarina, southern Brazil. Data were collected from January 2018 to December 2019, using 25 sites of camera traps among the study area. We collected 624 independent records from L. guttulus (108), L. pardalis (55), L. wiedii (77) and P. concolor (384) in a sampling effort of 12,266 camera-traps/day. All species analysed showed a non-uniform distribution of daily activity, when considering the two years. We report the peak of seasonal activity for all species between the months of June and September, coinciding with the Araucaria nut harvest in the study area, and with the increase in populations of small rodents. We also report a high overlap between the activity patterns of the four species. The daily and seasonal activity patterns of the species in this study seem to reflect the intrinsic dynamics of the Araucaria Forest, as well as possible adaptations to prey availability.
