SUMMARY 297trated the White Sea from the east, the second one – from the west. Blue mussel, no doubt,could only spread within upper layer of coastal water relatively warm in summer. The factof simultaneous colonization of the White Sea by these two species is a strong evidence ofseawater temperature stratification in the Gorlo Strait during the Preboreal climatic phase.Salinity stratification is also possible. Ecological features of species mentioned allow suggestingof salinity range in the upper White Sea water layer about 13‰ and in the deeperlayer no less than 25‰. At the same time, the lower seawater masses should be consideredvery cold (close to freezing point) all the year round in this period. As a result, we can suggestthe White Sea to be double-layer from the very beginning of its existence. The GorloStrait water should be also divided into two strata; otherwise the penetration of the coldwaterspecies Portlandia arctica cannot be explained.The most intensive invasion of boreal and Arctic-boreal species took place at the Atlanticclimatic phase, when the mean of air summer temperature exceeded contemporary oneby 1–2ºC. During the whole phase the threshold of the Gorlo Strait was about 70 m as distinctfrom 40 m in nowadays. (The depth can be easily calculated taking into considerationisostatic and eustatic variations of the sea level; see Fig. 85). The hydrodynamic regimeshould be weaker at that time, than presently, due to greater depth of the strait.Since Subboreal climatic phase, because of the sea level retrogression the hydrodynamicconditions resembling contemporary ones were formed. In spite of rising temperatures,the intensity of colonization of the White Sea by bivalve mollusks significantlydropped as a result in this phase. The difficulties in overcoming competition of previouslynaturalized species forming stable communities can be the second probable reason of thelow rate of contemporary invasion (Naumov, Berger, 2004).
