Examples of these spots include Baranof Island, which has a lack of glacial evidence on its southern end, suggesting lack of coverage during the LGM. Also, Coronation Island seems to have relatively minor glaciation. In support of possible refugia, a brown bear skeleton was found on Coronation dating back to 11630 years BP.
A glacial refugium (plural glacial refugia) is a geographic region which made possible the survival of flora and fauna during ice ages and allowed for post-glacial re-colonization. [ 1 ] [ 2 ] Different types of glacial refugia can be distinguished, namely nunatak , peripheral, and lowland. [ 3 ]
Last Glacial Maximum refugia were places in which humans and other species survived during the Last Glacial Period, around 25,000 to 18,000 years ago. [1] Glacial refugia are areas that climate changes were not as severe, and where species could recolonize after deglaciation.
European Last Glacial Maximum refugia, 20 kya. In biology, a refugium (plural: refugia) is a location which supports an isolated or relict population of a once more widespread species. This isolation can be due to climatic changes, geography, or human activities such as deforestation and overhunting.

What is probably the world's oldest ice, dating back 1.2m years ago, has been dug out from deep within Antarctica. Working at temperatures of -35C, a team of scientists extracted a 2.8km-long ...
Reindeer evolved during the last ice age to withstand temperatures as low as minus 94°F (minus 70° C. Yes, you read that right. This is an amazing feat, accomplished only by a select group of ...
Much of modern Finland is former seabed or archipelago: illustrated are sea levels immediately after the last ice age. Erratic boulders, U-shaped valleys, drumlins, eskers, kettle lakes, bedrock striations are among the common signatures of the Ice Age. In addition, post-glacial rebound has caused numerous significant changes to coastlines and ...
