We identified 42 different jaguars and you can computed its intercourse, ages class, and you may reproductive reputation
Abstract
Density is vital to have facts higher carnivore environment and conservation, however, quoting it’s got shown methodologically tough. We used 12 months from camera capturing to imagine jaguar (Panthera onca) occurrence and society construction on Los Llanos area for Venezuela into Hato Pinero ranch, where query try banned and animals is actually omitted regarding half ranch places. I projected mature jaguar densities which have spatial just take-recapture designs, using intercourse/reproductive state and you will lesson as the covariates. Patterns instead temporal variation obtained way more assistance than just patterns you to definitely welcome type ranging from coaching. Boys, reproductive people, and you can nonreproductive lady differed inside their occurrence, baseline detectability, and you will movement. A knowledgeable imagine of overall mature jaguar society occurrence is actually 4.44 anybody/one hundred kilometer 2 . Centered on reproductive female density and mean quantity of offspring for each women, we projected cub thickness within 3.23 people/one hundred km 2 and you may a complete density out-of 7.67 jaguars/one hundred kilometer dos . Projected jaguar population structure try 21% men, 11% nonreproductive female, 26% reproductive ladies, and you can 42% cubs. I conclude you to extending the brand new testing period to just one season expands the fresh detectability of females and you can cubs and you can renders occurrence estimates significantly more strong as opposed to the more prevalent small education. Our results show that the fresh new Venezuelan Llanos show essential jaguar environment, and additional, it stress the necessity of protected section and browse constraints to have carnivore conservation.
