- Аннотация: The Ponto-Caspian cladoceran Evadne anonyx (G.O. Sars, 1897) was recorded in the summer zooplanktonof the Southeastern Baltic (SEB) in 2010–2011. The quantitative parameters of the species were low.The share of the introduced species in the total abundance and biomass of zooplankton was not significant.The population of E. anonyx was represented predominantly by parthenogenetic females with 1–22 eggs.Among individuals, males were found and that allowed the suggestion of the presence of sexual reproductionand formation of gamogenetic eggs in the populations of E. anonyx in the SEB. Morphometric parameters ofpopulations of E. anonyx and fertility of parthenogenetic females in the SEB were comparable with those of Caspianforms. It is possible that, with the emergence of the new species E. anonyx, structural and functional changesmay take place in zooplankton community of half-closed Curonian and Vistula lagoons of the Baltic Sea.
