Seasonal and spatial patterns of eukaryotic phytoplankton communities in an urban river based on marker gene

Abstract The seasonal and spatial eukaryotic phytoplankton composition in the Fenhe River was investigated based on the 18S rDNA V4 region. The relationship between phytoplankton functional groups and environmental factors was explored to effectively capture the responses of these taxa to environmen...
