Lagged effects of anomalies in GEP on subsequent productivity anomalies. (a) January–June GEP anomaly is significantly correlated (p < 0.01) with GEP anomaly during the previous July–December period. (b) July–December GEP anomaly is significantly correlated (p < 0.01) with GEP anomaly during the previous January–June period. Reported statistics calculated with DBF and ENF forest data pooled. Open circles, ENF; filled circles, DBF. (a) r = 0.34, n = 132 and slope = 0.8. (b) r = 0.41, n = 153 and slope = 1.2.
