title: Seasonal and Interannual Dynamics of the Abundance of the Black Sea Alien Species Pseudodiaptomus marinus Sato, 1913 (Copepoda, Calanoida, Pseudodiaptomidae) in the Crimean Coastal Waters: Influence of the Temperature Factor
abstract: Observation on the occurrence of the Black Sea alien species Pseudodiaptomus marinus were initiated since this species was reported in coastal waters of Crimea, in 2016. Current study is focused on the 170–500 µm microplankton fraction represented by nauplii and first copepodite stages. These data were complemented by the mesoplankton fraction abundance contributed by copepodite stages II–V and adults. Samples were collected by plastic bottles at the sea surface and by Juday and Apstein plankton
