Formation of a fluvial non-parasitic population of Lethenteron camtschaticum as the first step in petromyzontid speciation.

Abstract excerpt

To elucidate the petromyzontid speciation process, the genetic independence of the fluvial non-parasitic populations within the anadromous parasitic Lethenteron camtschaticum was estimated by using polymorphic microsatellite loci. Abundant gene flow was revealed in multitemporal scales between potentially sympatric populations, suggesting ongoing gene flow resulting from imperfect size-assortative mating between...
