[Dynamics of Epilithic Algae Communities and Their Relationship with Environmental Factors During Storage and Non-storage Periods in the Three Gorges Reservoir].

In order to explore the composition of epiphytic algae and its related environmental factors, 12 sampling sites in the natural reaches and the backwater reaches (including perennial backwater sections and fluctuating backwater sections) were investigated among tributaries of the Caotang River, the Meixi River, and the Daxi River in the Fengjie district of the Chongqing section of the Three Gorges Reservoir under different hydrological regimes (i.e., storage and non-storage periods).

[Functional Group Characteristics of Planktonic Diatoms and Their Relationship with Environmental Factors in the Ruxi River].

To elucidate the functional group characteristics of planktonic diatoms and their relationship with environment factors in the Ruxi River, multivariate statistical analysis and functional group classification were conducted in this study. The success pattern of a diatom functional group and its driving factor were analyzed for the Ruxi River, a typical tributary of Three Gorges Reservoir, after the phytoplankton community and environmental variables were investigated at three different stages: level water period (April 2014), dry season (December 2014), and wet season (July 2014), based on the characteristic of water level. The results showed that there were 10 diatom functional groups in the Ruxi River: the A, B, C, D, L, MP, P, T, X3, and S1 groups, and among them, MP was the most groups, but the dominant group was D group.
