Ecological assessment of Burç Reservoir’s surface water (Turkey) using phytoplankton metrics and multivariate approach

The present study aimed to elucidate relationships between phytoplankton species and stressors using multivariate approaches and assess the environmental condition of Burç Reservoir’s surface water using phytoplankton metrics from September 2018 to August 2019 according to implementations of the Water Framework Directive. Burç Reservoir had a characteristic of a warm monomictic pattern. Phytoplankton functional groups (E, F, J, LO, LM, MP, P, S1, T, and W1) were found in the reservoir. A significant difference was found in total biovolume values changed from 2.28 mm3/L in November 2018 to 0.51 mm3/L in February 2019. The first two axes of canonical correspondence analysis explained 99.2% of relationships between stressors and phytoplankton assemblages.
