The problems of the extinction of aquatic plant species in Ivanovo region glacial lakes are discussed. As a result of research a sharp decrease in the number of rare hydrophytes (Elatine hydropiper, Isoetes lacustris, I. echinospora, Sparganium gramineum) has been established. The reasons are complex, they are associated with the eutrophication of ponds, heavy metals soil pollution, uncontrolled recreational loads and Elodea canadensis invaded into lake ecosystems. The ecological niche of Sparganium gramineum in the lakes is occupied by S. × longifolium, the hybridogenic origin of which is proved by modern molecular genetic analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
