Research overview: jaguar home-range size across habitats

Jaguar home ranges vary widely with habitat productivity and prey availability, from compact territories in rich wetlands to vast ranges in drier or less productive forests. This overview synthesizes telemetry studies showing that jaguars in the prey-rich Pantanal occupy smaller ranges at higher densities, while those in arid scrub or degraded forest range far more widely. It reviews how prey biomass, water, cover, and human disturbance shape ranging, and how male ranges typically exceed and overlap those of females. The synthesis connects spatial ecology to the densities jaguars reach in different landscapes and to the area needed to conserve viable populations. For enthusiasts it explains why jaguar numbers and territory sizes differ so dramatically across the Neotropics and why protecting productive riparian habitats yields the greatest conservation return for the species.
