Migration between continents: geographical structure and long-distance gene flow in Porpidia flavicunda (lichen-forming Ascomycota).

Abstract excerpt

Historical and contemporary geographical distribution ranges with their associated gene flow patterns interact to produce the genetic diversity observed today. Often it is not possible to separate out the impacts of historical events, e.g. past fragmentation, and contemporary gene flow, e.g. long-distance dispersal. Porpidia flavicunda is a lichen-forming ascomycete occurring circumpolar in the boreal to arctic...
