title: Long-term dynamics of the copepod invader Oithona davisae in coastal waters of the Black Sea
abstract: The results of a six-year monitoring of the abundance of the recent alien copepod Oithona davisae in the nearest coastal waters of Sevastopol are presented.

Then it decreases continuously until the complete disappearance of the species from plankton. The annual variability of the peaks of abundance is of a sinusoidal character with a two-year period and
