Drivers of jaguar (Panthera onca) and puma (Puma concolor) predation on endangered primates within a transformed landscape in southern Mexico

Biotropica, Volume 55, Issue 5, Page 1058-1068, September 2023., 2023
Jaguar and puma seem to increase predation on endangered primates under certain environmental conditions. Abstract Human pressures have increasingly placed keystone species, such as large cats, under threat. Together with forest loss, prey depletion is one of the main threats to the survival of jaguars (Panthera onca) and pumas (Puma concolor ...
