2016) and rapid evolution under changing environmental conditions (Hudson et al. The salmonid European whitefish Coregonus lavaretus forms a large species complex spanning across the north temperate regions of the Palaearctic, displaying high levels of phenotypic variation at the inter- and intra-population levels (e.g. Conflicts between morphological and molecular data are common in temperate freshwater fishes, as populations tend to be isolated from each other due to physical barriers, present a disjunct distribution, and show high levels of phenotypic and ecological differentiation (Taylor 1999 Adams et al. We argue that the data presented here are not sufficient to support a separation of the British European whitefish populations into three separate species, but support the delineation of different ESUs for these populations.Īccurate species delineation is fundamental for the practical protection and conservation of biota (Mace 2004), but the use of genetic markers sometimes disagree with traditional morphology-based taxonomy (Bickford et al. Principal component analysis and molecular ANOVA revealed separation between Scottish, English, and Welsh populations, with the Scottish populations being the most diverged. Population structure analyses indicated high genetic differentiation (global F ST = 0.388) between all populations but for the two Scottish populations (F ST = 0.063) and two English populations (F ST = 0.038). Here we used a dataset of 15 microsatellites to: (1) investigate the genetic diversity of British populations, (2) assess the level of population structure and the relationships between British populations. lavaretus (two in Scotland, four in England, one in Wales) were previously classified into three species, and recent taxonomic revision resurrected the previous nomenclature. In Great Britain, the seven native populations of C. Such variation has led to the assignment of many populations to separate species. The European whitefish Coregonus lavaretus complex represents one of the most diverse radiations within salmonids, with extreme morphological and genetic differentiation across its range.
