The spatial distribution and occurrence of species in the landscape are influenced by environmental conditions and the availability resources. Habitat fragmentation can cause the reduction or elimination of these resources leading to the decline or disappearance of populations and species. Some interactions such as predation and competition can also be factors influencing species distribution; these interactions may be intensified between related species and may adversely affect species distribution and abundance. The aims of this study were to evaluate occupancy rate of ocelot (_Leopardus pardalis_), the relative abundance index and competitive relations of the ocelot, the jaguarundi (_Puma yagouaroundi_) and puma (_Puma concolor_) in the northern of SÆo Paulo state. Camera traps were used from October 2012 to January 2015 in three protected areas of north and northeast state. The ocelot's occupancy rate in Jata¡ Ecological Station indicated a higher likelihood of species occupation in locations close to roads and showing higher biomass of prey, and a lower probability of occupying places nearly water courses. In State Park Furnas do Bom Jesus we observed a negative association of the puma with the ocelot and the jaguarundi, and a positive association between the ocelot and the jaguarundi; there was no overlaps of activity time between the ocelot and the jaguarundi, while the puma and ocelot co-occurred temporally. In Jata¡ Ecological Station, the ocelot and puma were positively associated and co-occurred temporally. The positive relation of ocelot with roads may be related their use for movements, and the preference for sites with greater biomass of preys indicates that the vegetation structure may be less important than the diet resources for this species. The negative association of smaller species with the puma was expected since the puma is the top predator in these communities. Although there was a positive association between ocelot and jaguarundi, there was a temporal separation between these species. Although the ocelot and puma showed a positive relation, it is possible that greater segregation between the two species occur in relation to their diets, which may explain the co-occurrence of these two species. |
