Spatial and temporal dynamics of bacterioplankton community composition in a subtropical dammed karst river of southwestern China.

ABSTRACT: River damming influences the hydro-physicochemical variations in karst water; however, such disruption in bacterioplankton communities has seldom been studied. Here, three sampling sites (city-river section, reservoir area, and outflow area) of the Ca²⁺ -Mg²⁺ -HCO₃ ^- -SO₄ ^2- water type in the dammed Liu River were selected to investigate the bacterioplankton community composition as identified by high-throughput 16S rRNA gene sequencing. In the dammed Liu River, thermal regimes have been altered, which has resulted in considerable spatial-temporal differences in total dissolved solids (TDSs), oxidation-reduction potential (Eh), dissolved oxygen (DO), and pH and in a different microenvironment for bacterioplankton.
