We analyzed the food habits of the jaguar (Panthera onca) and puma (Puma concolor) in a protected area surrounded by a fragmented landscape in northeastern Mexico. We estimated relative biomass of each prey species consumed; by analysis of 43 and 22 scat samples of jaguar and puma collected during 2010–2012. The diet of both felids was comprised mainly of wild artiodactyls; the collared peccary contributed 35.2% to the biomass of jaguar diets and white-tailed deer contributed 51.9% to puma diets. Diet composition of both felids showed moderate overlap (Pianka index = 0.57; Morisita index = 0.58), but use of the primary prey differed between species (P < 0.001). The diet of both felids included almost exclusively wild species, suggesting the presence of a good prey base that allows the coexistence of jaguars and pumas. Despite its small size and surrounding fragmentation, the Biosphere Reserve Sierra del Abra-Tanchipa is still an important refuge for large felids and their prey in northeastern Mexico.
