Chertoprud et al. (2012)
In salinities of about 19 psu, diversity and biomass of estuarine macrobenthic communities tend to be significantly higher than in any other region of the estuary.
Drake et al. (2002)
Species richness, abundance, and biomass decreased in the upstream direction, positively correlated with salinity. Highly significant spatial variation in macrofaunal communities along the salinity gradient. Salinity range: 0-40 ppt.
Montagna et al. (2002b)
Macrofauna increased abundances, biomass & diversity with increased inflow; decreased during hypersaline conditions. Macrofaunal biomass & diversity had nonlinear bell-shaped relationship with salinity: maximum biomass at ~19 ppt, maxiumum diversity at ~9 ppt. Meiofauna abundance increased with increasing inflow.
Chollett & Bone (2007)
Immediately after heavy rainfall (~25 psu), spionid polychaetes showed large increases in density & richness versus normal values (~41 psu).
Kalke & Montagna (1991)
Chironomid larvae & polychaete Hobsonia florida: increased densities after freshwater inflow event (1-5 ppt). Mollusks Mulinia lateralis & Macoma mitchelli: increased densities & abundance during low flow event (~20 ppt). Streblospio benedicti & Mediomastus californiensis: positively correlated with increasing salinity in low flow.
