Abstract

Wild felids play an important role in the dynamics of the tropical forests where they live, through the processes of depredation they exert on their prey. The populations of these carnivorous mammals have decreased throughout their range, due to conflicts with humans, habitat destruction and fragmentation. In order to know the abundance of wild cats in the Area of Protection of Flora and Fauna Sierra de Álamos-Cuchujaqui, a monitoring was carried out with the 105 trap cameras during two sampling periods (August-September and October-December of 2016) in two sites in the protected area. The duration of the sampling was 120 days, obtaining an effort of 3,474 camera days for the two periods. Sixteen species of mammals were recorded, among which highlights the jaguar (Panthera onca), the puma (Puma concolor), the bobcat (Lynx rufus) and the ocelot (Leopardus pardalis). The jaguar was photographed 13 times and in five stations within the area. Five individuals were identified, of which three were males and two were not able to determine their sex. The highest indices of abundance were for the puma (1.08) in the first period and for the ocelot (1.88) in the second period. A density of 1.43 (± 0.60) ind / 100 km2 of jaguar was estimated. The photographic trapping was an efficient tool to estimate the abundance and density of wild cats in the area and allowed to determine the presence and relative abundance of other mammal species.
