Dieta de quatro espéces de filostomídeos frugívoros (Chiroptera, Mammalia) do Parque Municipal do Cinturão Verde de Cianorte, Paraná, Brasil / Dieta de quatro espéces de filostomídeos frugívoros (Chiroptera, Mammalia) do Parque Municipal do Cinturão Verde de Cianorte, Paraná, Brasil

ABSTRACT

This study aimed at analyzing the diet of four species of frugivorous bats (Artibeus lituratus, A. fimbriatus, Sturnira lilium, Carollia perspicillata) captured in Cinturao Verde Municipal Park, city of Cianorte, state of Parana, considering possible variations in the use of fruits along the seasons of the year. Between October, 2004 and September, 2005, eighty-five samples of feces were obtained which revealed that A. lituratus and A. fimbriatus consumed, preferentially, fruits from Cecropia pachystachya, C. glaziouii, Ficus enormis, F. insipida and F. organensis. Sturnira lilium consumed, essentially, fruits from Solanum diflorum and S. americanum, whereas C. perspicillata fed, mainly, on Piper glabratum and P. hispidum fruits. As for the seasons of the year, there were diet changes, probably because of the fruits ripening period with the climatic seasonality apparently influencing the availability and use of feeding resources.
