The study area was sampled through opportunistic, transect and pitfall trap surveys conducted for three successive years. These surveys resulted in a total of 2,359 amphibian and reptile encounters, belonging to 20 amphibian and 69 reptile species from 24 total families. We present herein the records for one snake, one chelonian and two salamander species not previously recorded in the area.

This manual is an overview of captive management for all species of spider monkeys (Ateles). The authors have tried to cover the main aspects of captive management however there is a vast amount of literature relating to wild and captive spider monkeys available. If you would like further information about these topics, see page 16.

We investigated female-directed male aggression in 2 wild communities of spider monkeys (Ateles geoffroyi yucatanensis) from the Otoch Ma’ax Yetel Kooh reserve in Yucatan, Mexico to evaluate the sexual coercion hypothesis. The aggression occurred in 2 distinct forms: physical aggression and prolonged noncontact chases. The latter appeared highly ritualized in nature and accounted for >80% of all female-directed male aggression. Rates of prolonged chases, but not physical aggression, peaked when the female target was likely cycling and were associated with male place-sniffing of the substrate previously occupied by the female target. Prolonged chases were also associated with proceptive behavior directed from the female target toward her male attacker after the chase had ceased. Our data therefore suggest that prolonged chases are sexually motivated. Prolonged chases did not result in immediate copulation, but sometimes the female victim left the subgroup to travel alone with her male aggressor, and thus prolonged chases may be a form of male intimidation to coerce females into a mating consortship. However, as prolonged chases appeared highly ritualized, the chases may also be a form of male sexual display. Further investigation of the costs incurred by female recipients of prolonged chases is therefore required before one can interpret the behavior as sexual coercion.
