Resumen:
Most species of present a montane distribution with populations located at high altitudes. In this context, we proposed that populations of species could be genetically differentiated even at a local scale. This study supported that prediction, as a RAPD-based analysis of molecular variance revealed a high degree of genetic structure ( (st) = 0.157, = 0.001) and low gene flow ( (m) = 1.0) among four central populations of in Mexico, with a maximum geographic separation of about 140 km. The four populations also exhibited high levels of genetic diversity (mean Nei's genetic diversity = 0.3716; % polymorphism = 95.45%). The evolutionary implications of the genetic structure found in . for other species in the genus are discussed in the context of the naturally fragmented distribution and a set of life history traits shared by most species that could promote geographic isolation and limited gene flow.
