In this study, we analyzed the genetic variation of quetzals (Pharomachrus mocinno) throughout their geographic distribution to determine conservation targets. This species is found in patchy isolated cloud forests from Mexico to Panama. A multidimensional scaling and UPGMA analysis of a 286 RAPD fragment set resolved 3 genetic groups: cluster 1 (Mexican localities), cluster 2 (Guatemala, Nicaragua and El Salvador) and cluster 3 (Panama). The mean genetic diversity estimated by the Shannon index was 0.38, 0.22 and 0.32, for clusters 1, 2, and 3, respectively. The genetic differentiation among clusters was statistically significant. The highest percentage of genetic variation (70.86%) was found within populations using an AMOVA analysis. Our...
