Abstract

Density is vital for skills large carnivore environment and you may preservation, but estimating it has got demonstrated methodologically difficult. We conducted 12 months regarding cam trapping in order to guess jaguar (Panthera onca) thickness and you can inhabitants construction on the Los Llanos region of Venezuela towards the Hato Pinero ranch, in which bing search is actually blocked and livestock is omitted out-of 50 % of farm places. We estimated adult jaguar densities that have spatial get-recapture designs, having fun with sex/reproductive state and course because the covariates. Patterns instead of temporary adaptation acquired a lot more help than simply models one welcome variation between instruction. People, reproductive female, and nonreproductive people differed within density, standard detectability, and you can path. An educated guess of complete adult jaguar population occurrence is actually 4.forty-two somebody/a hundred kilometres dos . Centered on reproductive people thickness and you can suggest amount of kiddies for every single females, we estimated cub thickness at step 3.23 someone/one hundred kilometres 2 and you can a complete density from seven.67 jaguars/100 kilometres dos . Estimated jaguar populace structure are 21% guys, 11% nonreproductive lady, 26% reproductive people, and you may 42% cubs. I end you to definitely stretching the fresh testing several months to a single seasons expands the new detectability of women and you may cubs and can make occurrence quotes way more sturdy as compared to the usual brief degree.
