Conceptual

Occurrence is crucial to possess facts highest carnivore environment and you can preservation, but quoting it’s demonstrated methodologically hard. We used 1 year of camera trapping so you can guess jaguar (Panthera onca) occurrence and you will populace design on the Los Llanos region of Venezuela with the Hato Pinero ranch, where search was banned and you will animals is actually omitted out-of 50 % of ranch countries. I projected mature jaguar densities having spatial grab-recapture habits, using intercourse/reproductive county and you can tutorial since covariates. Patterns without temporary type obtained much more service than simply habits one desired adaptation between training. People, reproductive ladies, and you can nonreproductive girls differed within their occurrence, baseline detectability, and you may movement. An educated imagine off total mature jaguar populace occurrence are cuatro.49 people/one hundred kilometer 2 . Considering reproductive girls occurrence and you may imply quantity of young children per women, i projected cub density during the 3.23 somebody/100 km dos and you will an overall density out of 7.67 jaguars/a hundred kilometres 2 . Estimated jaguar population framework is 21% men, 11% nonreproductive females, 26% reproductive women, and you will 42% cubs. We conclude one stretching the fresh new testing several months to just one season develops the new detectability of women and you can cubs and produces thickness estimates much more powerful as opposed to the more prevalent brief education.
