摘要：THIS STUDY EXAMINED THE FEEDING HABITS OF THREE SPECIES OF FRUGIVOROUS BATS IN RELATION TO THEIR ROLE AS SEED DISPERSERS IN TWO LOCALITIES, ONE IN A NEOTROPICAL RAINFOREST AREA IN THE SOUTHERN PART OF THE MONTES AZULES BIOSPHERE RESERVE (REBIMA), AND THE OTHER IN EJIDO PLAYÓN DE LA GLORIA (PDLG). WE ESTIMATED THE RELATIVE ABUNDANCE OF ARTIBEUS LITURATUS, CAROLLIA PERSPICILLATA AND STURNIRA LILIUM. WE DETERMINED THE DIVERSITY AND THE SUCCESSIONAL CATEGORY OF FRUITS CONSUMED BY THESE SPECIES IN BOTH LOCALITIES THROUGH THE IDENTIFICATION OF SEEDS IN THEIR FECES. THE PLANT SPECIES DIVERSITY BASED ON SUCCESSIONAL CATEGORY SHOWED THAT A. LITURATUS AND C. PERSPICILLATA CONSUME FRUITS OF PIONEER SPECIES AS WELL AS PERSISTENT SPECIES, WHILE S. LILIUM ONLY FEEDS ON PIONEER SPECIES. DURING THE DRY SEASON A. LITURATUS AND C. PERSPICILLATA HAD HIGHER DIVERSITY AND RICHNESS VALUES OF PLANT SPECIES CONSUMED AT REBIMA, WHEREAS IN THE WET SEASON THEY SHOWED HIGHER DIVERSITY AND RICHNESS AT PDLG, INDICATING THAT THE DIVERSITY OF SEEDS COLLECTED BY BOTH DISPERSERS CHANGES WITH THE TIME OF YEAR. S. LILIUM PRESENTED HIGHER DIVERSITY AND RICHNESS VALUES OF PLANT SPECIES CONSUMED AT PDLG THROUGHOUT THE YEAR STUDY, INDICATING PREFERENCE FOR FRUITS FROM EARLY STAGES OF PLANT SUCCESSION.
