A nunatak is a type of glacial refugium that is located on the snow-free, exposed peaks of mountains, which lie above the ice sheet during glaciations. The identification of âdiversity hotspotsâ in areas, which should have been migration regions during major glacial episodes, is evidence for nunatak
163:
Lowland glacial refugia, unlike nunatak and peripheral glacial refugia, are found at low elevations rather than in mountains. Situated beyond the limits of ice shields, lowland refugia have been identified for a number of plant and animal species. In Europe, for example, researchers using allozyme

Traditionally, the identification of glacial refugia has occurred through palaeoecological analysis, which examines fossil organisms and their remains to determine the origins of modern taxa. For example, paleoecological approaches have been used to reconstruct the distributions of pollen in

of modern-day species, especially in birds, 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. In contrast, isolated geographic locales that host one or more

This type of refugium is created by an influx of hydrothermal waters which maintains a humid and warm microclimate that allowed thermophilous trees like oak (Quercus), linden (Tilia), and common ash (Fraxinus excelsior) to survive the last ice age in
Central Europe.
