Литоральные фитоценозы Кандалакшского залива Белого моря

Литоральные фитоценозы Кандалакшского залива Белого моря

Abstract

The paper investigates the structural features of the intertidal serf-protected phytocenoses of the littoral regions of the Kandalaksha Bay. The study was conducted in the Chupa Gulf near BBS "Kartesh", Knyazhaya Gulf and porting area of Kandalaksha. In all studied plant communities the dominant species is Fucus vesiculosus, the subdominant is Ascophyllum nodosum. Species diversity and biomass of macrophyte significantly reduces under chronic pollution. The main abiotic factors having the greatest impact on the bio-mass of phytocenoses of Kandalaksha Bay are the nature of soil and the presence or absence of anthropogenic pollution. The determining factor for the development of epiphytic macroalgae in the community is the concentration of nutrients. The lowest species diversity is observed in the Knyazhaya Gulf, inhabited by Halotolerant species only. In total 17 vulnerable species and 8 species of macrophytes resistant to anthropogenic pollution have been allocated.

Исследованы структурные особенности литоральных фитоценозов защищенных от прибоя участков литорали Кандалакшского залива. Исследование проводили в губе Чупа в районе ББС «Картеш», в губе Княжая и в портовой зоне г. Кандалакши. Во всех изученных фитоценозах доминирует Fucus vesiculosus, субдоминантом является Ascophyllum nodosum. Видовое разнообразие и биомасса макрофитов существенно снижаются в условиях хронического загрязнения. Основными абиотическими факторами, оказывающими набольшее влияние на биомассу фитоценозов Кандалакшского залива является характер, грунта и наличие или отсутствие антропогенного загрязнения. Определяющим фактором для развития эпифитов в сообществе макроводорослей является концентрация биогенов. Наименьшее видовое разнообразие отмечено в губе Княжая, где обитают только галотолерантные виды. Было выделено 17 уязвимых видов и 8 устойчивых видов макрофитов к антропогенному загрязнению.
