The current understanding of Arctic ecosystems is deeply rooted in the classical view of a bottom-up controlled system with strong physical forcing and seasonality in primary-production regimes. Consequently, the Arctic polar night is commonly disregarded as a time of year when biological activities are reduced to a minimum due to a reduced food supply.(More)
Multiple foundation species in a community may exhibit alternative ecological strategies. Barnacles Balanus crenatus Bruguiere and solitary ascidians Styela spp. often co-dominate on mixed sediments in the White Sea shallow subtidal, supporting numerous dependent organisms. Larvae of B. crenatus stay in plankton for several weeks, while ascidian tadpoles(More)

Unlike other known marine lakes from polar areas, which communicate with the sea by water percolation at the surface, Mogilnoe has a subterranean connection with the sea like tropical and subtropical anchialine lakes.(More)
