It is what biogeographers call a Holarctic species.
Holarctic phylogeography of Arctic char ( '' Salvelinus alpinus L. '') inferred from mitochondrial DNA sequences.
Complex biogeographic history of a Holarctic passerine.
The flowering plants on these ranges have high rates of endemism, with over 450 strictly endemic plant species, as a result of the long isolation of Holarctic taxa at these high elevations.
In contrast, the Grizzled Skipper is a more widely distributed Holarctic species, whose range extends not only to Alaska, Labrador and the arctic Quebec, but also across Asia to northern Europe.
DISTRIBUTIONWorldwide, char of the genus Salvelinus occur in the Holarctic: Eurasia and North America, including Iceland and Greenland.
From these refugia the ancestral lines began to disperse in the Holarctic region when the last ice age ended.
This last great area is divisible according to the same principles into the great northern belt of land, the Holarctic region and the

In this study we extend the sample size of prior studies in birds for cox1 (2776 sequences, 756 species) and target especially species that are known to occur parapatrically, and / or are known to hybridise, on a Holarctic scale.
