Chironomidae of semiaquatic lake shore habitats in the Karelian Isthmus (northwestern Russia)
Shores of lentic waters are poorly studied as habitats of Chironomidae. We investigated floating shore marsh surrounding the lakes Bol’shoe Rakovoe (Äyräpäänjärvi or Eteläjärvi) and Okhotnich’e (Muolaanlampi), shallow mesotrophic wetlands in the Karelian Isthmus. Our research aimed to identify speci...
