Spatial analysis of molecular variance (SAMOVA). Results of the spatial analysis of molecular variance showing the genetic affinity between Mexican samples of Campostoma ornatum. The most likely subdivisions of the whole distribution area were (i) four groups, when the increment of FCT was the largest (ΔFCT = 0.06) and (ii) 13 groups, when the decrease of FCT was maximum (ΔFCT = - 0.26).
