Fig. 1From: Growth response to climate and drought change along an aridity gradient in the southernmost Pinus nigra relict forestsClimatic trends in annual mean temperature and total precipitation for the five study sites. Linear regressions and correlation coefficients for temperature series are displayed (P < 0.05), while 20-year moving mean averages are presented in the case of precipitation series (see Table 2 for an analysis of precipitation trends). Sites’ codes are as in Table 1 Back to article page
