Abstract
Most species of Pinguicula present a montane distribution with populations located at high altitudes In this context we proposed that populations of Pinguicula species could be genetically differentiated even at a local scale This study supported that prediction as a RAPDbased analysis of molecular variance revealed a high degree of genetic structure Φ st = 0157 P = 0001 and low gene flow N m = 10 among four central populations of Pinguicula moranensis 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 = 03716 polymorphism = 9545 The evolutionary implications of the genetic structure found in P moranensis 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 Pinguicula species that could promote geographic isolation and limited gene flowThe authors thank Nestor A Mariano and Gumersindo Sánchez for their valuable assistance in improving the DNA isolation and amplification procedures An early draft of this manuscript was reviewed by Eduardo Cuevas and César Abarca We also are grateful to Raul I Martínez and Rubén Pérez Ishiwara for field assistance and logistical support
