文摘

Despite a narrow range of salinity, we observed significant effects on nitrate-reducing microbes. Positive relationship between salinity and denitrifier abundance. Salinity can affect community structure of both denitrifiers and DNRA-capable microorganisms. Potential for salinity increases and saltwater intrusion to affect nitrogen cycling in wetlands.
