Abstract
A total of 1840 individuals from 28 species (19 reptiles and 9 amphibians) were found inGorgona Island, during june and july 2001. Based on 32 transects placed in four areas withdifferent antropic perturbation degree (Prison, palm plantations, secondary forest and primaryforest) it was found that the species richness was higher at the secondary forest. The speciesregistered at primary and secondary forest where very similar as well as the species present at theprison and the palm plantations. A Canonical Correspondence Analysis (CCA) showed that Boaconstrictor, Basiliscus galeritus, Ameiva bridgesii and Epipedobates boulengeri were found to beassociated to open areas and their distribution was hardly affected by the environmental temperature.From the following species associated with forested areas, the canopy cover over the microhabitatinfluenced the distribution of Eleutherodactylus gularis, Eleutherodactylus achatinus and Bothropsatrox, while the understory cover influenced the distribution of Atelopus elegans, Bufo typhonius,Micrurus mipartitus y Enyalioides heterolepis
