Abstract

We studied the species of amphibians from Serranía de Las Quinchas, in the mid Magdalena Valley region of Colombia, comparing the data from a recent fieldwork with museum records and literature. We present a list of 50 species of amphibians (Anura and Caudata). In our survey, we recorded 36 species, of which 6 represented new records. One of the most interesting record is that of the genus Oedipina, since this is the first time the genus is recorded for the Cordillera Oriental. The number of species is what would be expected in a humid tropical forest of the mid-Magdalena river valley, given the co-occurrence of amphibian faunas distributed in the sub-Andean, Caribbean, and Chocó biogeographic regions.

Highlights

There are currently 821 species of amphibians reported for Colombia, being the country with second-highest species richness, after Brazil (Acosta-Galvis 2000, 2019, Frost 2019)

Summary

Introduction

There are currently 821 species of amphibians reported for Colombia, being the country with second-highest species richness, after Brazil (Acosta-Galvis 2000, 2019, Frost 2019). In Colombia, between 1985 and 2000, the areas that showed one of the highest increases in agricultural activities were the Cordillera Oriental and the Magdalena Valley (Rodríguez-Eraso et al 2013). These processes have negative implications for conservation because both of these regions are considered as hotspots of biodiversity (Myers 1998). The fragmentation, loss and degradation of tropical forest habitats is one of the primary causes of the amphibian population declines in Colombia. Such a situation makes it necessary to conduct. We present the results of an inventory made along an altitudinal assessment in different seasons with the purpose to detect species composition beside the first inventories, and to begin a monitoring conservation plan about the status of the amphibian fauna
