I would like to compliment Mr. FrogO_Oeyes on your excellent discussion of various artificially created biomes.
The only addition that I can presently think of which could be added to the list would be a Refugium, which is used mostly in marine reefkeeping.
A refugium is a biome whose purpose is to encourage the growth of plants and animals which scavenge, or clean, the environment of harmful pollutants, without which, the biosphere (collective biomes) would suffer. A refugium is an integrated biome, which requires separate maintenance from the other physically connected biomes. The physical separation of the refugium must be maintained, either because the biological requirements of the refugium plants and animals are unique, or because the refugium plants and animals would be attacked (eaten or damaged) by the inhabitants of the other interconnected biomes.
