title: <i>Pseudodiaptomus marinus</i> Sato, 1913 in the Black Sea: morphology, genetic analysis, and variability in seasonal and interannual abundance
abstract: Calanoid copepod <i>Peudodiaptomus marinus</i> Sato, 1913 was first recorded in Sevastopol Bay in the northern Black Sea in September 2016. We performed regular observations of this new invasive species between October 2016 and December 2018. We conducted bi-weekly plankton sampling at three stations located within or adjacent to Sevastopol Bay. This is the first paper to combine (i) a detailed morphological study, (ii) molecular genetic analysis, and (iii) an investigation of <i>P. marinus</i>
