Abstract
We analysed relationships of chemical and biological variables with the help of statistics for phytoplankton communities of seven lakes in the Regional Landscape Park “Slavyansky Resort”, Ukraine that were studied during 2007-2013. Lake communities were divided into two groups: northern deep lakes Ripne, Veysove, Garache, and Slipne under high salinity and organic load influence, and southern shallow lakes Levadne, Chervone, and Lake under influence of mineral ions and organic load. Abundance and biomass fluctuated synchronously and correlated with species richness in deep lakes but not in shallow lakes. Two types of communities were revealed: (1) low species-rich communities in moderate conductivity waters and low-organic load, and (2) species rich communities in high conductivity and organic load waters. We found salinity indicator Dunaliella salina (Dunal) Teodor. in deep northern lakes with CCA. Adlafia minuscula (Grunow in Van Heurck) Lange-Bert. in Lange-Bert. et Genkal and Chaetoceros muelleri Lemmerm. were bio-indicators of high salinity and alkalinity, and biosensors of acidic water in shallow southern lakes. Cyclotella stelligera (Cleve et Grunow) Van Heurck and Navicula gregaria Donkin were indicators of silica and biosensors of carbonates. Therefore, water conductivity and pH, which were closely related to organic pollution, were found as major regulators of phytoplankton in studied lakes.
