Structure and species diversity of topical groups of mollusks in lakes of the Solovetsky Islands and Onega Peninsula, northwestern Russia

A study reveals that mollusk communities in the lakes of Solovetsky Island exhibit higher species richness and density compared to continental lakes, while also showing reduced dominance levels. This insular environment imposes unique constraints on the diversity and structure of these mollusk groups, limiting their total species richness and the range of structural variants. Despite this, certain species dominate in abundance within these insular groups. The research compares the topological groups of mollusks between Solovetsky Island's lakes and those on the Onega Peninsula, highlighting the distinct ecological dynamics shaped by the island's isolation.
