Phylogeography of the barbel (Barbus barbus) assessed by mitochondrial DNA variation.

abstract：:Human activities have increasingly introduced plant species far outside their native ranges under environmental conditions that can strongly differ from those originally met. Therefore, before spreading, and potentially causing ecological and economical damage, non-native species may rapidly evolve. Evidence of geneti...
