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.
Biodiverse coral reef community. A refuge is a concept in ecology, in which an organism obtains protection from predation by hiding in an area where it is inaccessible or cannot easily be found.
Coastal refugia are locations of refuge located on uncovered coastal regions or islands. Due to a lower sea level during the last glacial period, it is suspected that the exposed continental shelf played a large role in acting as a refugium to many different organisms as well as potential route for migration.

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
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 ]
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area, or becoming extirpated from an area they once lived), go extinct, or diversify into more species.
