Lagged Pearson correlations coefficient between environmental variables (SOI, SIE) and demographic parameters of three seabirds at Terre Adélie, Antarctica. ( Values within parentheses represent lags in year for the first significant coefficient correlation during the overall period. Significant correlations at a 0.10 (*), 0.05 level (**) and 0.01 level (***) calculated with bootstrap methods are indicated.)
