Feeding behaviour of the bat Phyllostomus hastatus (Pallas 1767) in jackfruit Artocarpus heterophyllus Lamarck (Moraceae), in Ilha Grande, Rio de Janeiro State, Brazil

RESUMO

Artorcarpus heterophyllus fruit is the largest tree fruit, weighing up to 36 kg and was introduced in Brazil during the XVIII century. During a mammalian diversity research developed at Ilha Grande at least five Phyllostomus hastatus bats were observed eating jackfruit. Jackfruit availability is high almost all year long at Ilha Grande and it is possible that P. hastatus restricts the use of this fruit during low availability periods of other food resources. Although seed carrying was not observed, the disperser role of P.hastatus on A. heterophyllus can not be neglected.
