Pseudodiaptomus Marinus

Pseudodiaptomus marinus was initially discovered at the end of September 2016 in a sample taken during a long-term plankton survey of Sevastopol Bay started in 2002. We found 6 females and 12 copepodites (I-V stages) of P. marinus at the center of Sevastopol Bay (St. 3) on September 22. At the mouth of Bay (St. 2) the species was not found. Both females and copepodite stages I-V of P. marinus were found at the both stations on November 11. Abundance of P. marinus increased to 1236 individuals in sample (1373 ind/m3) at the center of the bay. Moreover, two individuals of P. marinus nauplii identified by Sazhina, were found in this sample. At the mouth of the bay abundance of the invasive species reached 103 individuals in sample (103 ind/m3). It is considered to be native to the Northwestern Pacific Ocean, but now species is widespread across the world. Brilinski described in details its distribution in the World's oceans. Recently P. marinus has been found in the Atlantic Ocean in the North Sea and in the Mediterranean Sea. P. marinus is a typical estuarine coastal copepod, living in shallow eutrophic inshore waters. It is tolerant to a wide range of salinity (2.5-35 ptt) and temperature (5-28 ºC) and has the highest invasive potential. Thus species is adapted to relatively low salinities and low winter temperatures of the Black Sea. Copepodite stages at both stations indicate the existence of reproducing populations. Thus, very likely P. marinus is the new established species in coastal area of the Black Sea. As other recent pelagic invaders – the copepods Acartia tonsa Dana 1849, Oithona davisae Ferrari F. D. & Orsi 1984; ctenophores Mnemiopsis leidyi A. Agassiz, 1865 and Beroe ovata Bruguiere, 1789 - P. marinus was most probably brought into Sevastopol Bay in the ballast water of ships. Long-term studies at basin scale are needed to estimate the structural changes in the Black Sea zooplankton community.

The associations and ecological conditions of the existence of modern diatoms of the North-West (Pridneprovsky), Prikerchensky and Eastern regions of the subtidal zone of the Black Sea are considered. Based on the unity of the composition of the Present and Sarmatian-Meotian diatom flora, an attempt has been made to model some of the ecological c situation of the Late Miocene Euxinian basin.
