BACTERIOPLANKTON OF WATER-BODIES IN THE LOWER DNISTER BASIN

Abstract

Bacterioplankton is among the most important components of aquatic ecosystems as organic matter microbiological transformation is one of the main self-purification and natural water quality formation processes. Regional Centre for Integrated Monitoring and Ecological Studies, Odessa National I. I. Mechnikov University, has been carrying out field surveys in the Lower Dnister basin since 2003. One of activities during surveys is observation of bacterioplankton spatial distribution and seasonal dynamics of its number and biomass in all main water-bodies in the area: Kuchurganskiy Liman (estuary), Rivers Dnister and Turunchuk, lakes Beloye, Svinoye and Tudorovo, as well as the Dnistrovskiy Liman (estuary). Besides, there are three points monitoring of the Dnister and Turunchuk Rivers where observations of bacterioplankton quantitative characteristics are carried out all year round.
