   <abstract xml:lang="ru">
    <p>В статье представлен обзор публикаций, посвященных экологии и динамике “цветения” цианобактерии Gloeotrichia echinulata (J.E. Smith) P. Richter в олиготрофных и мезотрофных озерах. На примере оз. Плещеево обобщены многолетние (за последние 100 лет) данные по составу и продуктивности фитопланктона. Показано, что с 2017 г. в озере ежегодно наблюдаются вспышки вегетации G. echinulata, вызывающие интенсивное “цветение” воды. Массовое развитие этого вида обусловлено сочетанием антропогенной эвтрофикации (повышение фосфорной нагрузки за счет стоков с водосбора), климатического потепления и гидрологической изоляции озера. Особое внимание уделено механизму обратной связи: G. Echinulata не только реагирует на повышение содержания фосфора, но и активно мобилизует его из донных отложений, усиливая эвтрофикацию и создавая условия для собственного доминирования. Обсуждаются экологические последствия: угроза для популяции эндемичной переславской ряпушки (Coregonus albula), стимуляция развития сопутствующих токсичных цианобактерий и ухудшение качества воды, что создает риски для водоснабжения г. Переславля-Залесского.</p>

    <p>This article reviews publications on the development of the cyanobacterium Gloeotrichia echinulata in oligotrophic and mesotrophic lakes, with a special focus on Lake Pleshcheyevo (Yaroslavl region, Russia). The study summarizes the results of phytoplankton investigations conducted over the past 100 years. Since 2017, annual blooms caused by G. echinulata have been observed in the lake. The mass development of this cyanobacterium is driven by a combination of anthropogenic and climatic factors: increased phosphorus loads from adjacent watersheds, rising water temperatures, and reduced water exchange, which promotes stagnation. G. echinulata plays a key role in internal phosphorus loading by transferring this element from bottom sediments into the water column, thereby accelerating eutrophication and further stimulating bloom formation. The proliferation of G. echinulata poses a serious threat to the lake’s ecosystem, particularly to the endemic Pereslavl vendace (Coregonus albula), and may facilitate the concurrent development of other toxic cyanobacteria. Moreover, mass blooms degrade water quality and jeopardize the municipal water supply of the town of Pereslavl-Zalessky.</p>
