Unraveling the variability and genetic structure of barker frog physalaemus cuvieri (leiuperinae) populations from different regions of brazil

Abstract

The barker frog Physalaemus cuvieri is widely distributed in South America and is found in all regions of Brazil. Significant intraspecific morphological variation in this species has been reported. To determine the genetic structure of the natural Brazilian populations of P. cuvieri, 10 different populations geographically separated by 99.41 to 2936.75 km were evaluated using 10 polymorphic microsatellite loci. In addition, mitochondrial DNA data were analyzed to determine genetic distance between the populations. The genetic variation was found to be significant in most of the populations (H E ranged from 0.40 to 0.59, and allelic richness ranged from 2.07 to 3.54). An F ST value of 0.27 indicated that high genetic structure was present among the P. cuvieri populations. STRUCTURE.
