Appearance of a New Species of Cladocera (Anomopoda, Chydoridae, Bosminidae) in the Hypersaline Moynaki Lake, Crimea

In 2018–2019, a year-round study of the hypersaline Moynaki Lake, western Crimea, was conducted. In mid-summer 2018, along with Moina salina, which had previously been reported from the lake, the year-round presence of further two cladoceran species, Chydorus sphaericus and Bosmina ( Eubosmina ) cor...

Summary:In 2018–2019, a year-round study of the hypersaline Moynaki Lake, western Crimea, was conducted. In mid-summer 2018, along with Moina salina, which had previously been reported from the lake, the year-round presence of further two cladoceran species, Chydorus sphaericus and Bosmina ( Eubosmina ) coregoni , was recorded there for the first time. None of those species had ever been registered from hypersaline waters anywhere else. Their introduction seems to have occurred because of a salinity decrease, even though the modern level of salinity has been observed the same level for at least the past 20 years. The presently highly eutrophic environment of Moynaki Lake is probably sufficiently energy-rich to sustain cladoceran osmo-adaptations.
