| The authors hypothesized their common origin from an Atlantic refugium after the last glaciation. |
|
| Perhaps the lineage survived as refugium species and thus repopulated during the post-Cretaceous recovery. |
|
| We suggest that the shallow epicratonic platform area of the Canadian Shield may have served as a refugium for relatively archaic taxa. |
|
| Moreover, resting stages also afford species a temporal refugium from adverse conditions. |
|
| Sheep in the Alaska refugium evolved into the slender-horned Dall sheep Ovis dalli, those farther south into the heavy-horned Rocky Mountain and desert bighorns Ovis canadensis. |
|
| The extinct pine species Pinus matthewsii has been described from Pliocene sediments in the Yukon areas of the refugium. |
|
| Alaska was a glacial refugium because it had low snowfall, allowing a small population to exist. |
|
| A Pleistocene refugium with high biological and topographic diversity, Bwindi Impenetrable National Park is a rich source of soil microorganisms such as Actinomycetes, which are a potential source of new antibiotics. |
|
| This refugium extended east into at least half of Ivvavik where sites along the Firth River have produced 8,000 year-old projectile points, as well as bison hunting sites. |
|
| The area is considered of biogeographic interest because it lies in the transition between East and West African vegetation zones and has evidence of a Pleistocene refugium. |
|
| In a saltwater aquarium, copepods are typically stocked in the refugium. |
