Abstract

Jaguars (Panthera onca Linnaeus, 1758) have been extirpated from nearly 55 % of their original range in America and from almost 24 % in Paraguay. Here we present evidence of the presence of jaguar close to the most populated areas of Paraguay, in a human–dominated landscape in the Humid Chaco forests, highlighting how without other pressures, jaguars can inhabit densely populated areas and potentially disperse between established populations.

Highlights

  • The jaguar (Panthera onca) is the largest wild felid in the Americas, found from the southwestern United States to northern Argentina

  • The Chaco is the portion of Paraguay that lies west of the Paraguay River

  • The study area is located in the Paraguayan Humid Chaco, where the landscape is composed of a mosaic of natural grasslands, palm groves, wetlands, and islands of dense forest
