Abstract

The shift of dominant species from diatoms to flagellates together with nutrient abundances was predicted and verified using data obtained from large scale mesocosm experiments. The prediction was done using a system dynamics model shown in authors’ previous study. With common parameters, most of the variables were predicted well. Some important factors such as wind mixing, migration by flaegllates, etc. were pointed out.
