В исследованной лагуне было обнаружено 35 вида бентосных беспозвоночных животных, а также 9 видов морских трав и водорослей. В лагуне наблюдается хорошо выраженный вертикальный градиент структуры сообщества макробентоса (от верхней литорали к средней, нижней и сублиторали) и менее выраженный продольный от кутовых более заиленных и опресненных местообитаний к мористым. Проведенный статистический анализ позволяет выделить сублиторальный макробентос (доминируют моллюски Macoma balthica и полихеты Terebellides stroemi, Nereimyra punctata, Pontoporeia femorata, Scoloplos armiger, Phyllodoce maculata ), сообщество макробентоса нижней и средней литорали при доминировании Macoma balthica, Mya arenaria (больше в средней литорали), Arenicola marina, Littorina littorea, Mytilus edulis (больше в нижней литорали) и сообщество макробентоса верхней литорали вместе со средней кутового района, где преобладают мелкие эвритопные виды Peringia ulvae, Tubificoides benedii и Littorina saxatilis . В лагуне вследствие ее мелководности, отгороженности от моря, преобладания илисто-песчаных осадков и некоторой опресненности преобладают в основном собирающие детритофаги, их процент снижается в средней и нижней литорали и возрастает в сторону сублиторали и верхней литорали.</p></abstract><trans-abstract xml:lang="en"><p>Features of the specific, spatial and trophic structure of macrobenthos communities in a lagoon ecosystem located at the outlet of the inner area of the Kislaya Bay (Kandalaksha Gulf, White Sea) were studied. 35 species of benthic invertebrates, as well as 9 ones of seagrasses and algae, were found in the lagoon. In it, there is a well–marked vertical gradient in the macrobenthos community structure (from the upper littoral to the middle, lower, and sublittoral) and a less pronounced longitudinal one, from more silty and desalinated coastal habitats to marine ones. Our statistical analysis made it possible to identify a sublittoral macrobenthos (dominated by Macoma balthica mollusks and polychaetes Terebellides stroemi, Nereimyra punctatata, Pontoporeia femorata, Scoloplos armiger, Phyllodoce maculata ), a community of macrobenthos of the lower and middle littoral, dominated by Macoma balthica, Mya arenaria (more in the middle littoral), Arenicola marina, Littorina littorea and Mytilus edulis (more in the lower littoral) and the macrobenthos community of the upper littoral, together with the inner district middle littoral, dominated by small eurytopic species Peringia ulvae, Tubificoides benedii and Littorina saxatilis . In the lagoon, due to its shallow waters, isolation from the sea, predominance of silt-sand sediments and some freshening, mainly detritiphages predominate; their percentage decreases in the middle and lower littoral and increases towards the sublittoral and upper littoral.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лагунные экосистемы</kwd><kwd>макробентос</kwd><kwd>видовое разнообразие</kwd><kwd>пространственное распределение</kwd><kwd>трофическая структура</kwd><kwd>Белое море</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lagoon ecosystems</kwd><kwd>macrobenthos</kwd><kwd>species diversity</kwd><kwd>spatial distribution</kwd><kwd>trophic structure</kwd><kwd>White Sea</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Burkovsky I.
