Refugium (fishkeeping)
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. It is a "refugium (population biology), refugium" in the sense that it permits organisms to be maintained that would not survive in the main system, whether food animals, anaerobic denitrifying bacteria, or photosynthesizers. For some applications water flow is limited in order to protect plants or animals that require slow flow. The refugium light cycle can be operated opposite to the main tank, in order to keep total system pH more stable (due to the uptake of acid-forming CO2 by photosynthesis occurring in the refugium during its "daylight" hours). One volume guideline for a refugium is 1:10 main tank volume. A refugium may be used for one or more purposes such as denitrification, nutrient export, plankton production, circulation, surface agitation to improve oxygen exchange with the atmosphere or e ...

Last Glacial Maximum Refugia
Last Glacial Maximum refugia were places ('' refugia'') in which humans and other species survived during the Last Glacial Period in the Northern Hemisphere, around 25,000 to 20,000 years ago. Sub-Saharan Africa and Australia were not affected by the glaciation, although vast areas of those continents were too dry for human habitation of any sort, even by the most specialised and well-adapted foragers. New Zealand had no humans at the time. Some recent archaeological evidence suggests the possibility that human arrival in the Americas may have occurred prior to the Last Glacial Maximum more than 20,000 years ago, including possibly areas adjacent to ice sheets, but research is still in an early stage. The best attested shelters are therefore mainly those in Eurasia. Several of them have been studied.

Refugium Range
The Refugium Range is a low, small mountain range comprising the mountains/hills of the Brooks Peninsula on northern Vancouver Island, British Columbia, Canada. It has an area of and is a subrange of the Vancouver Island Ranges which in turn form part of the Insular Mountains.Refugium Range in the Canadian Mountain Encyclopedia The range was named in 1981 by an expedition which found that peaks higher than were above the glaciers during the last ice age and are therefore a refugium with unique plants.

Refuge (Buddhism)
In Buddhism, refuge or taking refuge refers to a religious practice, which often includes a prayer or recitation performed at the beginning of the day or of a practice session. Since the period of Early Buddhism until present time, all Theravada and mainstream Mahayana schools only take refuge in the Three Jewels (also known as the Triple Gem or Three Refuges, Pali: ''ti-ratana'' or ''ratana-ttaya''; Sanskrit: ''tri-ratna'' or ''ratna-traya'') which are the Buddha, the Dharma and the Sangha. However, only Vajrayana school includes an expanded refuge formula known as the Three Jewels and Three Roots. Taking refuge is a form of aspiration to lead a life with the Triple Gem at its core. Taking refuge is done by a short formula in which one names the Buddha, the dharma and the saṅgha as refuges. In early Buddhist scriptures, taking refuge is an expression of determination to follow the Buddha's path, but not a relinquishing of responsibility. Refuge is common to all major school ...
