Figure 6. Standardized breeding success (mean ± se) in the first breeding attempt of 188 males recruiting at ages 3–4 years (closed dots, dashed line) and 133 males recruiting at ages 5–6 years (open dots, solid line) in relation to annual mean sea surface temperature anomalies during the natal years of their mothers.

To simplify visualization, we show conditional plots from the estimated values of the interaction male recruiting age x SSTA in the mother's natal year.
