Thickness is extremely important for facts large carnivore environment and conservation, however, estimating this has shown methodologically hard. We conducted 1 year from cam trapping so you’re able to estimate jaguar (Panthera onca) occurrence and you will population structure regarding Los Llanos region of Venezuela into the Hato Pinero ranch, in which bing search is banned and you can animals try excluded regarding 50 % of farm countries. I estimated mature jaguar densities with spatial capture-recapture designs, playing with intercourse/reproductive county and you may example as the covariates. Activities instead temporary adaptation obtained alot more support than simply models you to definitely desired version between instructions. Men, reproductive women, and you will nonreproductive women differed inside their thickness, standard detectability, and you may direction. A knowledgeable estimate of complete mature jaguar population thickness is actually 4.forty-two some body/one hundred kilometer 2 . According to reproductive people density and you will indicate quantity of kiddies for each women, we estimated cub density in the step three.23 individuals/one hundred kilometres dos and you will an overall total occurrence out-of eight.67 jaguars/a hundred kilometres 2 . Estimated jaguar society design is actually 21% people, 11% nonreproductive girls, 26% reproductive girls, and you can 42% cubs. I ending you to definitely extending new testing months to just one 12 months increases the newest detectability of females and cubs and you will renders occurrence quotes a whole lot more robust as compared to the more common brief education.
