DOIAbstract
Both historical and contemporary processes influence the genetic structure of species, but the relative roles of such processes are still difficult to access. Population genetic studies of species with recent evolutionary histories such as the New Zealand endemic scallop Pecten novaezelandiae (<1 Ma) permit testing of the effects of recent processes affecting gene flow and shaping genetic structure. In addition, studies encompassing the entire distributional range of species can provide insight into colonization processes. Analyses of genetic variation in P. novaezelandiae (952 individuals from 14 locations, genotyped at 10 microsatellite loci) revealed a weak but significant regional structure across the distributional range of the species...
