Patterns of long-term changes in fouling communities developing on artificial substrates in the White Sea are reviewed. The most significant shifts occurring in these communities are caused by biological successions that can last for several decades. Terminal stages of succession are the communities of a mussel Mytilus edulis or a solitary ascidian Styela(More)
The ability of the sponge Halichondria panicea to assimilate into the fouling communities of the blue mussel Mytilus edulis and the solitary ascidian Styela rustica has been studied in a field experiment, in which sponge fragments have been introduced artificially into epibenthic communities. The growth of H. panicea was suppressed greatly in the presence(More)
Role of lipids and fatty acids (FA) in littorial and sublittorial White Sea mussels Mytilus edulis L. was studied at various stages of reproductive in the phenotypic adaptation (acclimation) to changes of the sea water salinity. The obtained data indicate differences in the mussel lipid and fatty acid spectra, which are connected both with their location(More)
Current classification of principal ecological groups of hydrobionts is an eclectic one as it confuses two fundamentals, one dealing with organismic ecomorphology and another with water body's topology. This leads to difficulties in determination of interrelations between benthos and fouling communities. The littoral fouling communities cannot be considered(More)
The effect of excretion-secretion products (ESP) of five abundant fouling invertebrate species (bivalve mollusks Hiatella arctica and Mytilus edulis, solitary ascidia Styela rustica, sponge Halichondria panicea, and sea starAsterias rubens, inhabiting the White Sea) on the biochemical status of blue mussel M. edulis was assessed by the dynamics of lysosomal(More)
The impacts of different concentrations of the excretory-secretory products (ESPs) of the solitary ascidian Styela rustica (Linnaeus, 1767) and the sponge Halichondria panacea (Pallas, 1766) on the settlement, metamorphosis, and mortality rates of H. panacea larvae were studied in a laboratory experiment. At high concentrations, substances released into the(More)
