Aquarists will commonly house this alga, perhaps with others, in a refugium.

In recent years the Berlin Method is often supplemented with a refugium.

Gibraltar may have represented the refugium of the Neanderthals.

A refugium is, as its name suggests, a sheltered area that shares water with the primary, or display, tank.

A popular technique for aquarists, is to grow macroalgae in a sump or refugium.

Eastern parts of the group were therefore unglaciated, and served as an important refugium for silicicolous plants.

A refugium provides many benefits, which include nitrate reduction, as well as providing a natural food source.

A refugium may also be used to export nutrients, when packed with macroalgae such as Chaetomorpha, and live rock.

In a saltwater aquarium, copepods are typically stocked in the refugium.

The study results actually show a recent population expansion from a single glacial refugium, therefore the current populations are homogeneous in terms of genetics.

The refugium is the largest throughout the Western Asian / near Eastern region.

It was thought to provide evidence that Australia was a refugium for animals that had gone extinct elsewhere.

Mount Nimba serves as refugium for numerous Western African species.

In home aquariums, the refugium is typically located in the cabinet underneath the main tank.

The refugium and sump are often housed in a single tank with a system of dividers to separate the compartments.

Peaks in the area higher than 700m (2,300 ft) were above the glaciers during the last ice age and are therefore a refugium with unique plants.

The Refugium is dying.

Schloss Solitude was originally designed to act as a refugium, a place of quiet, reflection and solitude (thus the name).

Various types of macroalgae can be grown and harvested from the refugium as another means of nitrate export.

Rather its subsequent spread further west occurred later, in the post-glacial period from a postulated South Caucasian refugium.

In the Refugium:

In addition, some sumps have a compartment that can be converted into a refugium, helping to filter out excess nutrients such as nitrates.

Refugium may refer to:

Tu pauperum refugium (original version).

The term "Refugium peccatorum" is also used other works of Roman Catholic Marian art.
