Article Synopsis
- The study analyzes a protected jaguar population in Belize using 14 years of camera-trap data (2002-2015), examining individual survival and behavior across 3,075 detection events of 105 adult jaguars.
- High and consistent survival rates (φ = 0.78) were observed for both sexes, while temporary emigration was stable at 0.20 per year, indicating a stable population of resident males with fluctuating transient males and low detection rates for females.
- The findings suggest the need for extended survey periods to improve female detection and emphasize the importance of long-term monitoring to better understand the dynamics of elusive predator populations.
We present the first study that evaluates jaguar-puma interactions in the arid lands of northern Mexico, where jaguars have their northernmost breeding population and both predators are persecuted for livestock depredation. We tested whether jaguars are the dominant species in this unique ecosystem, where: (1) pumas outnumber jaguars, (2) pumas are better adapted to arid environments, and (3) jaguars and pumas are of similar size. We analyzed four years of data with two approaches; a two species conditional occupancy model and an activity patterns analysis.

We used the Barker robust design model which combines data from closed sampling periods and resight data between these periods to estimate apparent survival and abundance. We identified 467 jaguar pictures that corresponded to 48 jaguar individuals.
