In biology, a refugium (plural: refugia) is a location which supports an isolated or relict population of a once more widespread species. This isolation ( allopatry ) can be due to climatic changes, geography, or human activities such as deforestation and overhunting.
During the LGM, 27-66% of Africa was a refugium for humans. Humans thrived here because of the abundance of humidity, accessibility of woodlands, and lastly precipitation/access to water. The Zambezi, Omo river, and the Great Rift Valley lakes were major sources of water in southern Africa. [24]
In fishkeeping, a refugium is an appendage to a marine, brackish, or freshwater fish tank that shares the same water supply. It is a separate sump , connected to the main show tank. [ 1 ] It is a " refugium " in the sense that it permits organisms to be maintained that would not survive in the main system, whether food animals, anaerobic ...
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 ]
Refugium, plural refugia, the Latin for "refuge" or "hideaway", may refer to: Refugium (fishkeeping) , an appendage to a marine, brackish, or freshwater fish tank that shares the same water supply Refugium (population biology) , a location of an isolated or relict population of a once widespread animal or plant species
In support of possible refugia, a brown bear skeleton was found on Coronation dating back to 11630 years BP. This may show that there was a refugium nearby that this bear could have traveled from. It may also indicate that Coronation was a refugium that provided a food source for the bear. [3]
Glacial refugium and Late Glacial population expansion [ edit ] The region may have been a major refugium for Paleolithic peoples during the Last Glacial Maximum , apparently playing a major role as source for the repopulation of Europe after that extremely cold period ended.
A number of artificial "refugia" consisting of concrete tanks approximating conditions in Devils Hole were attempted to ensure the species' survival should the natural population at Devils Hole die out. The Hoover Dam Refugium for Endangered Desert Fish was established in August 1972, with the first twenty-seven pupfish translocated in October ...
