Model II regression results for swimming <i>Corophium volutator</i> variables tested against total density or biomass of <i>C. volutator</i> residents in the mud in the upper Bay of Fundy, summer 2010.

Both swimmer and mud resident variables were log10-transformed prior to analysis. Student’s t-test evaluates if the slope is significantly different from 0, while Clark’s T-test evaluates if the slope is significantly different from 1 (MacArdle 1988). r = correlation coefficient.
