Partition of food resources among four species of frugivorous bats (Chiroptera, Phyllostomidae)

This study was carried out in the region of Londrina, Paraná, Brazil in three different areas: a primary forest, a disturbed primary forest and an open area. Within 207 hours of capture, 990 individuals were collected, 939 of them being fruit-eating bats. Carollia perspicillata (Linnaeus, 1758), Sturnira lilium (Geoffroy, 1810), Platyrrhinus lineatus (Geoffroy, 1810) and Artibeus lituratus (Olfers, 1818) were the four most collected species in a total of 899 individuals. A. lituratus was found in greater number in all the areas, showing significant variation in relation to the size of the forests. The partition of food resources among the four most collected species was known through the analysis of their feces. The coexixtence of these species can be explained by their investing in different foods or their diverging time activity.
