Rozas et al. (2005)
Increased density and biomass with increases in freshwater inflow and reduced salinities. Salinity ranged from 1-13 psu.
Rutger & Wing (2006)
Infaunal community in low salinity regions (2-4 ppt) showed low species richness and abundance of bivalves, decapods, and Orbiniid polychaetes, but high abundance of amphipods and Nereid polychaetes compared to higher salinity regions (12-32 ppt).
Hourston et al. (2010)
Nematodes have the tendency to be most abundant in downstream areas of estuarine environments at all times of the year due to the salinity concentration closer to the marine areas being higher at >29 ppt. Estuarine productivity is presumed greater at lower to moderate salinities.
Galveston Bay National Estuary Program (1992)
Tubificioides heterochaetus and Peloscolex gabriellae are indicative of environments with <10 ppt salinities.
FINS (2006)
Studies have shown that oysters are incapable of tolerating salinities <5 ppt for more than ~3 days. Exposure to >25 ppt waters will increase the risk of Perkinsus marinus and Thais haemostoma on oyster reefs. Salinities above 10 ppt typically induce spawning in estuarine oysters.
