Figure 3.

Relationship between cohort-specific adult sexual size dimorphism [ln(male wt)/ln(female wt)] and the NAO index of the winter preceding birth of the cohort. The circled point significantly influenced the regression, and the correlation excluding it is reported in parentheses. (Inset) Least-squares mean estimates of cohort-specific weights of adult males and females in relation to the NAO index of the winter preceding their birth (males: r = 0.36, P = 0.04; females: r = −0.27, P = 0.14). Bold, P < 0.05.
