Abstract

PALACIOS-RODRIGUEZ, Lizeth; RENGIFO-MOSQUERA, Jhon; BIOL, Magleyvi Roa Panesso  and  BIOL, Yakeline Palacios Asprilla. Wealth and distribution of Hylides (Hylidae: Anura) in a tropical pluvial forest area in the Chocó Department, Colombia. rev. colombiana cienc. anim. Recia [online]. 2018, vol.10, n.2, pp.154-166. ISSN 2027-4297.  http://dx.doi.org/10.24188/recia.v10.n2.2018.650.

In the present study, the richness and distribution of Hylides in the tropical rain forest area were determined, plant coverings were established (primary and secondary forest) for a better analysis of the group in the central area of the department of Chocó. For the estimation of the wealth we used the method of surveys by visual encounters (Visual Encounter Survey "VES"), registering a total of 137 ind., Grouped into five genera and eight species of Hílidos. There was a difference in the distribution of the species according to the vegetation cover, registering better values in secondary forest (s = 8 and n = 103); in the community the best represented genera were Dendropsophus, Scinax and Boana who were present in both coverages, and in specific term Boana boans and Smilisca phaeota. In the use of habitat, significant difference was found in the vertical positions (P=1.34), as well as the substrates evaluated (P=1.66) these differences are evidenced in soil position and substrates branches. The results revealed that the Hílidos frequent the secondary forests because of their heterogeneity that holds the ideal conditions and ecological requirements that these species require for their development.
