Climatic Signals from Intra-annual Density Fluctuation Frequency in Mediterranean Pines at a Regional Scale.

By contrast, a highly significant negative correlation with summer temperatures (from June to September) was observed in P. pinaster ( r = −0.5 with T min , r = −0.6 with T max , and r = −0.6 with mean temperature), where the most negative correlations were found in July ( r = −0.5 with T min , r = −0.6 with T max , and r = −0.6 with mean temperature; Figure 5C ).
