Abstract
The
State Park Mata dos Godoy has 42 identified bat species, among which 21
are frugivorous and belong to the Phyllostomidae family. Current study
investigated the concentrations of carbohydrate, lipid and protein in
fruits consumed by Artibeus lituratus, Carollia perspicillata and
Sturnira lilium to understand their potential differentiated food
preferences. The Sampling effort it was from April/2013 to March/2014.
Animals captured in mist nets were identified in the field and
maintained in cotton bags for 30 minutes to defecate. The diet was
inferred from fecal samples analyzed in the laboratory, the fruits whose
seeds were found in the feces had the determinations of the nutrients
accomplished by centesimal composition method. Kruskal-Wallis test and
Dunn's multiple comparison method verified the most abundant nutrients
for each species of bat. Whereas Carollia perspicillata and Sturnira
lilium feeds mainly in food with carbohydrates that provide them with
more energy, the diet of Artibeus lituratus is richer in carbohydrates
and lipids. Only fruits considered scarcely represent a complete
nutrition for the three bat species, however, the complementarity with
other food items such as leaves, pollen, and insects, can provide a
complete nutrient diet for these animals.
