Dynamics of Morphofuncitonal Groups of Phytoplankton in the Rybinsk Resrevoir and Assessment of the Resevoir Water Quality by the Community Index

The changes in the ratio of species representing different morpho-functional groups, identified by physiological, morphological and ecological parameters [29] were analyzed based on the study on phytoplankton in different reaches of the Rybinsk Reservoir in 2000-2005. Water quality was assessed by the Q index of communities, developed taking into account the proportions of these groups. This assessment was compared with the evaluation using the values of Pantle-Buck saprobity index and phytoplankton biomass.

Automated summary

The study analyzed the changes in the ratio of species representing different morpho-functional groups among phytoplankton in different reaches of the Rybinsk Reservoir from 2000 to 2005, and compared water quality assessment methods.
