Water quality drives the regional patterns of an algal metacommunity in interconnected lakes

Abstract The metacommunity approach provides insights into how the biological communities are assembled along the environmental variations. The current study presents the importance of water quality on the metacommunity structure of algal communities in six river-connected lakes using long-term (8 y...
