Geoffroy's cats at the northern limit of their range: Activity patterns and density estimates from camera trapping in Bolivian dry forests

Abstract

We used camera traps to survey Geoffroy's cats, Oncifelis geoffroyi, at six dry forest sites in Bolivia. Cumulative activity patterns across all sites are principally nocturnal though the species is active by day in both summer and winter. At two sites the number of captures and recaptures was sufficient to estimate abundance using the software Capture, and in turn a population density of 9-40 per 100 km2 for the two sites. Geoffroy's cats are present in all dry forest types surveyed: Chaco savannas, Chaco dry forest, Chaco transitional forest, Chaco-Chiquitano transitional forest, Chaco-Cerrado transitional forest and Chiquitano dry forest. They are most abundant at the driest site, the only one with grassland formations and where ocelots are absent. Camera trapping records tend to be more numerous in the dry season, suggesting seasonal changes in behavior and habitat use. © 2006 Taylor & Francis.
