Abstract

Ocelot Leopardus pardalis is one of the most widespread species in Ameri- ca. Nevertheless, its ecology, distribution and population status are not well known in sev- eral countries, including Costa Rica. Here we present the first published population density estimations in Costa Rica and the first effort for the Caribbean slope of the country. Using camera-trapping, we estimated ocelot density through capture-recapture analysis within the Talamanca-Caribbean Biological Corridor. An abundance of 8 and 5 individuals were esti- mated by Mo and Mh models, respectively. Based on previous home-range studies, three Effective Sampling Areas (ESA) were used to estimate absolute density. Density was calcu- lated in 8.95, 10.33 and 11.61individuals (Mo model) and 5.59, 6.45 and 7.25 (Mh model) individuals × 100 km -2 for the maximum, mean and minimum ESA estimates, respectively. Gross extrapolations of the expected population size indicate a low abundance and co- dependence between the corridor and surrounding areas for the long term maintenance of the species in the region.
