Fig. 4: Spearman correlations between tree longevity and site-level tree-ring characteristics.

The color, shape and orientation of ellipses are mapped to coefficient values. Abbreviations: MS, mean sensitivity; AC1, first-order autocorrelation; Rbar, mean inter-series correlation; EPS, express population signal; SNR, signal-noise ratio; Rt, resistance; Rc, recovery; Rs, resilience. Only statistically significant correlation coefficients (p < 0.05) are displayed.
