Food habits of jaguars and pumas in Jalisco, Mexico

摘要: Jaguars (Panthera onca) and pumas (Puma concolor) are sympatric over much of their geographic range in Mexico South Central America. We investigated diets these felids around the Chamela-Cuixmala Biosphere Reserve western Jalisco, Mexico. Diets were determined from scat analyses documentation prey cadavers. Relative biomass each species consumed by jaguars was estimated analysing 65 puma 50 jaguar scats collected 1995 to 1998. Both fed mainly on mammals, with white-tailed deer (Odocoileus virginianus) dominating diet (54% 66% respectively). There a high degree overlap between diets, but had broader food niche than jaguars, ability exploit smaller may give them an advantage when faced human-induced habitat changes.
