Spatial ecology of Paraguay’s last remaining Atlantic forest Jaguars ( Panthera onca ): implications for their long-term survival

Jaguars (Panthera onca) in Paraguay's last remaining Atlantic forest exhibit extreme isolation, with 75% of their locations within protected areas. The study, using GPS telemetry, found that their mean home range size was approximately 160 km², comparable to Brazilian populations but smaller than those in Argentina and other regions. Surprisingly, human population density or the Human Footprint Index did not influence home range size or movements, underscoring the critical role of protected areas for these endangered big cats. This research highlights the precarious survival of Paraguay's Atlantic forest jaguars, emphasizing their dependence on conservation efforts within isolated remnants.
