The ocelot (_Leopardus pardalis_), as most neotropical felids, is elusive and difficult to observe in the wild. Using camera trapping, the objectives of this study were to identify variations in the photo capture rate and in the maximum distance moved of ocelots between seasons, and to estimate their abundance by capture-recapture method in the northern part of the Cardoso Island State Park. Minimum home range of the ocelot and the number of photographs of other felids were also recorded. I identified eight individuals (one male, five females and two individuals of sex not confirmed). It was observed an increase of the ocelot photo capture rate and the maximum distance moved in the dry season, suggesting an increase in the movement pattern and in home range use in the drier period, although these variations between seasons had been more observed for the male than the females. In a period of 45 nights (13 trap stations), six individuals were identified and the density estimated (ñ SE) was 0,21 (ñ 0,03) and 0,4 (ñ 0,05) ocelots/km2 (depending of the method used to calculate the effective survey area). Those values are within the range of density estimates reported for the species in mainland areas. Minimum home ranges of individuals photographed in at least three trap stations was 10 km2 for the male and ranged between 0,2 and 3,5 km2 for four females. For a total of 1475 traps night, ocelots had the greatest number of photo capture (91), followed by the puma (22), and the little spotted cat (1). This was the first work to collect data of population size of ocelot in an island area of Coastal Atlantic Forest, also confirming the presence of little spotted cat on this island. Implications for the monitoring and conservation of the ocelots in the Cardoso Island were discussed. |
