Fig. 4. Residuals of the fecundity-size relationship and number of sperm cells for multiparous female Tanner crab from Glacier Bay, Alaska, hatching and extruding a subsequent clutch in the field (FE) with access to males (circles), or hatching and extruding a subsequent clutch fertilized with stored sperm in the laboratory (LE) without mating (triangles). Linear regression indicated that residuals of fecundity-size did not vary significantly with sperm cell counts for either LE (dotted line; F = 0.05, df = 8, r² = 0.01, p <0.82) or FE (solid line; F = 1.87, df = 20, r² =0.09, p <0.19) females.
