A preliminary study of resource overlap between howling monkeys (Alouatta palliata) and other arboreal mammals in the tropical rain forest of Los Tuxtlas, Mexico

摘要: Potential resource overlap between howling monkeys and other arboreal mammals was studied in the rain forest of Los Tuxtlas, Veracruz, Mexico. Eight species belonging to orders Primates, Carnivora, Rodentia, Marsupialia were found share canopy trophically with monkeys. These made up 77% Alouatta 23% mammalian biomass under consideration. The porcupine spider monkey only that also fed on leaves. However, this feeding niche, is important folivore depression derived from leaf-eating insects more important. eight may exert pressure upon fruit resources, for they consumed 75% estimated total dry weight fruit/ha/yr by mammals.
