Abstract
Thickness is extremely important to own insights higher carnivore ecology and you may conservation, however, estimating it’s got shown methodologically tough. I conducted 12 months out-of digital camera capturing in order to guess jaguar (Panthera onca) occurrence and you can populace build regarding the Los Llanos region of Venezuela towards Hato Pinero ranch, where browse try banned and you can livestock try excluded off 50 % of farm places. I projected mature jaguar densities which have spatial get-recapture patterns, playing with intercourse/reproductive condition and you will tutorial once the covariates. Models rather than temporary variation obtained so much more support than just designs you to definitely invited variation ranging from instruction. Boys, reproductive women, and you will nonreproductive females differed inside their density, standard detectability, and course. A knowledgeable imagine out of full mature jaguar population occurrence try cuatro.49 anybody/a hundred kilometres 2 . Predicated on reproductive ladies thickness and you may imply number of kids each female, we estimated cub density on step three.23 somebody/one hundred kilometer dos and you may an overall total occurrence off seven.67 jaguars/100 kilometres dos . Projected jaguar inhabitants structure is 21% males, 11% nonreproductive female, 26% reproductive people, and you will 42% cubs. I ending one extending the fresh sampling several months to just one year increases new detectability of women and you can cubs and you will tends to make density prices even more robust when compared to the usual brief education. Our abilities reveal that the newest Venezuelan Llanos represent essential jaguar environment, and extra, it stress the necessity of safe parts and you will search limits to own carnivore preservation.
