Distribution patterns of American Arctic lichens
Maps showing typical American Arctic lichen distribution patterns are given, including broad ranging circumpolar, boreal forest outlier, Appalachian extensions, arcto-Pacific (Beringian), amphi-Atlantic, American Arctic endemic, Great Plains and Arctic, and western states and eastern arctic disjunct...
