To identify the taxonomic richness, spatial distribution, and phylogeographic relationships of freshwater mollusks within the upper Konda River basin in Western Siberia.
Surveyed freshwater mollusks across various water body types throughout the upper Konda River basin within the Western Siberian taiga zone.
Characterized species richness of bivalves and gastropods and evaluated phylogeographic affinities and haplotype variation relative to European and Eurasian populations.
Tested an a priori classification of local water bodies based on the community structure of their malacocenoses.
Recorded 27 freshwater mollusk species (19 bivalves and 8 gastropods), exhibiting a taxonomic structure distinct from adjacent Western Siberian faunas and the middle reaches of the Konda River.
Found that local populations share their closest phylogeographic relationships with populations from European Russia and Europe, alongside significant intrapopulation haplotype divergence in several taxa.
Demonstrated that mollusk communities in floodplain water bodies and large lakes differed statistically significantly from each other and other water bodies, whereas main river channels, tributaries, and subordinate waters showed no significant differentiation.
