- Abstract
Population parameters provide essential information for conservation efforts aimed at target species. We used the spatially explicit capture-recapture method to estimate the jaguar density and population size in the Gurupi Jaguar Conservation Unit (JCU), located in the most threatened ecoregion of the Amazon. The estimated density of 2.62 individuals/100 km2 in a continuous forest of over 10,000 km2 implies a small effective population size, underscoring the threat to the long-term viability of the Gurupi JCU's jaguar population. We recommend urgent forest restoration actions to reduce fragmentation and improve connectivity between Gurupi JCU and other forest fragments to facilitate jaguar gene flow.
