The Distribution of Moina micrura Kurz, 1875 (Crustacea: Moinidae) in the Russian Part of the Vistula Lagoon (Baltic Sea)

Abstract

The species Moina micrura Kurz, 1875 (Crustacea: Cladocera), which is new for the Vistula Lagoon of the Baltic Sea, was recorded there for the first time. Over the past years, the species has formed a stable opportunistic population, which may become dominant under optimal abiotic and trophic conditions. The continuing eutrophication of the Vistula Lagoon and local climate warming in recent decades are, apparently, the main reasons for the successful naturalization of the species in this water body.
