Relationship between thermotolerance, deciduousness and leaf traits. Scatter-plots, Pearson’s correlation coefficients (r), and Spearman’s rank correlations (r s ) for thermotolerance (T50, °C), deciduousness index (DI, %), leaf mass per area (LMA, g·m−2), leaf size (LA, cm2). LMA and LA were log transformed, and DI was converted to a proportion and logit transformed to better approximate normality. Spearman’s rank correlations are for untransformed variables. Best fit lines were plotted using type II ordinary least squares linear regressions. Evergreen and deciduous species are represented by grey and open circles respectively; ns - not significant, *p < 0.05, **p < 0.01.
