Fig. 1From: Sex differences in contaminant concentrations of fish: a synthesis a Ratio of whole-fish PCB concentration in males to whole-fish PCB concentration in females as a function of expected percent change in whole-fish PCB concentration of female fish immediately after spawning due to release of eggs. b Ratio of whole-fish Hg concentration in males to whole-fish Hg concentration in females as a function of expected percent change in whole-fish Hg concentration of female fish immediately after spawning due to release of eggs. Fitted regression line is shown. Attained significance level, P, of the F test for significance of the regression line is also shown. Data taken from Tables 1 and 2 Back to article page
