Glacial refugium

A glacial refugium (plural refugia) is a geographic region which made possible the survival of flora and fauna in times of ice ages and allowed a post-glacial re-colonization.[1] Different types of glacial refugia can be distinguished, namely nunatak, peripheral and lowland refugia.[2] Glacial refugia have been suggested as a major cause of the distributions of flora and fauna in both temperate and tropical latitudes.[3][4][5] However, in spite of the continuing use of historical refugia to explain modern-day species distributions, especially in birds,[6][7] doubt has been cast on the validity of such inferences, as much of the differentiation between populations observed today may have occurred before or after their restriction to refugia.[8][9]
