Abstract

Occurrence is extremely important to own facts large carnivore environment and you can preservation, but estimating this has confirmed methodologically tough. We conducted one year out-of digital camera capturing so you can estimate jaguar (Panthera onca) occurrence and you can population framework on the Los Llanos region of Venezuela with the Hato Pinero ranch, where browse is prohibited and you can animals is actually omitted off 50 % of farm countries. We projected mature jaguar densities having spatial bring-recapture activities, using gender/reproductive county and you can lesson since covariates. Habits without temporal variation gotten far more assistance than simply models you to acceptance variation ranging from sessions. People, reproductive women, and you may nonreproductive female differed inside their density, baseline detectability, and you may movement. An educated guess away from overall mature jaguar populace density is actually cuatro.forty two anybody/a hundred kilometer 2 . Centered on reproductive girls thickness and you can mean amount of girls and boys each females, i projected cub density within 3.23 somebody/a hundred km dos and you can a total occurrence of seven.67 jaguars/a hundred km 2 . Projected jaguar society construction try 21% men, 11% nonreproductive women, 26% reproductive females, and you will 42% cubs.
