Salinity effects

Insecta tend to be indicative of freshwater environments with salinities from 0.0 to 6.2 psu. Ampelisca abdita, Macoma mitchelli, Mulinia lateralis, Parandalia ocularis, and Streblospio benedicti are indicative of brackish environments with salinities from 15.0 to 26.2 psu. Apseudes sp. A, Corbula contracta, Periploma cf. orbiculare, Amphiodia atra, and Minuspio cirrifera are indicative of marine environments with salinities from 27.2 to 28.9.

Can tolerate salinities between 0 and 30 ppt. They are considered estuarine organisms.

This estuarine study had shown that C. errans are incapable of tolerating lower salinities of ~0.5 to 15 ppt. Abundance and salinity were positively correlated.

Sustained exposure (> 30 d) to salinity < 10 ppt significantly decreased survivorship.

These insects are known to be highly abundant in regions of low salinities, <5 ppt.
