Assessment of jaguars Panthera onca (Mammalia: Carnivora: Felidae) and their prey in Manu National Park

Jaguars (Panthera onca) in Peru's Manu National Park exhibit high density and widespread distribution, with estimates suggesting 193-241 individuals across the lowlands. A short-term study using 136 camera trap stations across 820 km² found jaguar densities of 2 to 2.5 individuals per 100 km², with no clear patterns in space use linked to environmental variables, prey availability, or competitors. Most prey species also showed high occupancy (>0.70), including ocelots (psi = 0.83) and pumas (psi = 0.25). The research suggests jaguars are abundant and resilient to spatial variations in habitat and human pressures, providing critical insights for conservation efforts in this UNESCO World Heritage Site.
