Investigations performed in the last decade indicate that there have been important changes
in the zooplankton composition and structure in the Black Sea. However, contrasting events …

Coastal plankton show fluctuations in abundance and species composition. Resting stage
(cyst) production is a common strategy adopted by hundreds of plankton species to ensure …

The ongoing transfer of harmful organisms by ship**, especially via ballast water
transport, may result in a change of biodiversity, alteration of ecosystems, negative impacts …

This review is a first attempt to summarize data on the records and distribution of 240 alien
species in fresh water, brackish water and marine water areas of Ukraine, from unicellular …

The Black, Azov, and Caspian sea drainages (ie, Ponto-Caspian region) have an extensive
and long history of species introductions. Here we review patterns and mechanisms of …

All over the world hypersaline lake/lagoons are threatened by climate change. The marine
Bakalskoye Lake (Ukraine) was studied in 2000-2012. The paper considers changing …

Seasonal and interannual dynamics of abundance of the recent invader O ithona davisae (C
opepoda: C yclopoida) were investigated in S evastopol B ay from O ctober 2005, when the …

Acartia tonsa and Oithona davisae are typically near-shore species which were transferred
to the Black Sea with ship ballast water and established self-sustaining populations in …

Long-term, regular studies of coastal plankton communities were resumed in 2002, based
on bi-weekly plankton casts at three stations located within and adjacent to Sevastopol Bay …

It was reported for the first time that Acartia tonsa was present in the Black Sea as early as in
1976. A. tonsa was found in the Mediterranean Sea in 1985. So, this copepod was initially …
