Research overview: jaguar ecology in continuous Amazon rainforest

The Amazon basin holds the largest remaining expanse of jaguar habitat, and the cat's ecology there differs from open wetlands. This overview synthesizes research on jaguars in continuous rainforest, where lower prey visibility and dispersed resources lead to larger ranges and lower densities than in the Pantanal, and where the cat preys on peccaries, deer, primates, and reptiles. It reviews how rivers structure movement, how the vast intact forest offers refuge from human pressure, and how monitoring such cryptic populations is especially challenging. The synthesis frames the Amazon as the jaguar's core stronghold by sheer area even if local densities are modest. For enthusiasts it explains why the rainforest, though harder to study, is indispensable to the species' long-term survival, providing the connected expanse that buffers jaguars against the fragmentation affecting populations elsewhere.
