Contrasting hydrological states are associated with sediment bacterial community variation and micropollutant biodegradation potential in a river-connected floodplain lake.
Hydrological contraction is a defining feature of river-connected floodplain lakes, but its association with sediment bacterial communities and contaminant biodegradation potential remains incompletely understood. During one observed wet-to-dry transition in Dongting Lake, China, we combined sediment physicochemical an...
