Son M. Alien molluscs in fresh and brackish waters of the Northern Black Sea Region (recent state, risk assessment, and ecological prediction)

Species composition, taxonomy, ecology, and zoogeography of exotic species and nearby aliens are discussed. New data on chronology of its expansion is cited. Particular direction of invasion - "Black Sea Coastal corridor" was marked in first. It allows exchange of exotic species between lower stretches of larger river basins in the studied region. Were developed and tested the approaches to analysis and risk assessment for alien species introductions that used as environmental indicators. The risk assessment procedures and water quality indicators on alien species were tested for selected ecosystems (assessment units) within Black Sea Coastal corridor of invasions and other ecosystems of the Northern Black Sea Region. Forecasting of invasion based on analysis of potential vectors of invasion is grounded.
