Abstract

The features of the species, spatial, and trophic structure of macrobenthic sublittoral communities were studied in two coastal lagoon ecosystems of the White Sea. The Ermolinskaya and Nikol’skaya inlets are highly silted lagoon ecosystems with a simplified trophic structure of the macrobenthos community and a predominance of the trophic group of collecting detritophages. In the sublittoral of the studied lagoons, 24 species of invertebrates, as well as four species of marine higher plants and algae (Zostera marina, Cladophora sericea, Fucus vesiculosus, and Chorda tomentosa), were found. The lagoon ecosystem of the Ermolinskaya Inlet was characterized by the highest species diversity, total density, and biomass of species populations of macrobenthos, while the ecosystem of the Nikol’skaya Inlet was characterized by lower indices. In the lagoon of the Nikol’skaya Inlet, which was better protected from the sea waves and currents, a greater development of littoral euryhaline marine and brackish-water species of macrobenthos was observed, while more marine sublittoral species were found in the lagoon of the Ermolinskaya Inlet, which is less protected from the sea.

Ermolinskaya和Nikol'skaya入口(Kandalaksha湾,白海)泻湖系统中大型底栖动物的种类,空间和营养结构的某些特征

摘要

在白海的两个沿海泻湖生态系统中研究了大型底栖近岸群落的种类,空间和营养结构特征。Ermolinskaya和Nikol'skaya入口是高度淤积的泻湖生态系统,其大型底栖动物群落的营养结构得到了简化,并且主要收集藻类的营养层。在所研究的泻湖的近沿海,有24种无脊椎动物以及4种海洋高等植物和藻类(Zostera滨海,Cladophora sericea,Fusus vesiculosusChorda tomentosa)), 被发现。Ermolinskaya入口的泻湖生态系统的特征是大型底栖动物的物种多样性,总密度和物种种群具有最高的生物量,而Nikol'skaya入口的生态系统的特征在于较低的指数。在可以更好地免受海浪和海流影响的尼科尔斯卡亚入海口的泻湖中,观察到大型底栖动物的滨海euryhaline海洋和微咸水物种得到了更大的发展,而在该湖泊的泻湖中发现了更多的海洋近海物种。 Ermolinskaya Inlet,从海上受到的保护较少。
