Abstract: Sex ratios of natural populations of Tigriopus californicus are correlated with the salinity fo the pool that they were taken from. All pools samples above 70 ppt had a greater percentage of females than males. Salinity tolerance tests showed that females were more resistent to salinity stress. It is suggested that the observed trends of sex reations in the field may be due to differential mortality.
