Differential fruit choice in two simpatric monkey species and frugivorous bats in southern Mexico

In order to identify the role played by plant species as a food source in the fruit election of dispersing agents (Alouatta pigra Lawrence 1933, Ateles geoffroyi Kuhl 1820 and frugivorous bats), we developed a study in dry tropical forests in Yucatan, Mexico. We recorded the fruits consumed by frugivorous bats using collectors and, for monkeys, we implemented the focal animal method. The number of fruits consumed by primates (A. pigra and A. geoffroyi) and bats were recorded, 342 and 386, respectively. It was determined that bats deposited fruits with some percentage of pulp, while monkeys contributed more with a fruits without pulp (pairwise LSD contrast p 0.05). Among the variety of fruit species in the diet of primates, we detected that A. pigra chose mostly not an abundant species such as Enterolobium cyclocarpum Jacq. Griseb. (1860) instead of those more abundant (Manilkara zapota (L.) P. Royen (1953) and Brosimum alicastrum Sw. subsp. alicastrum C.C. Berg (1972)). The type of fruit and seed handling caused by primates would be more beneficial to seed germination than those applied by bats. Moreover, this election and fruit handling could depend on the characteristics of fruits and space-temporal availability of plant species as a food source.
