Coupled Salinity-Redox Gradients Shape Dissolved Organic Matter characteristics and Its Linkages with microbial Functional Potential in Intertidal Sediments.
Estuarine intertidal sediments occur in freshwater-seawater mixing zones where hydrological processes simultaneously alter salinity and redox conditions, potentially regulating dissolved organic matter (DOM) transformation and microbial processes. However, how DOM and its interactions with microbial communities respond...
