Correlations between daily radius change and climate parameters (relative air humidity, precipitation, air temperature) and soil water content at the dry-mesic (a, filled circles) and xeric site (b, open circles) from April through October 2007 and 2008 (n = 424). Pearson correlation coefficient (r) and Kendall’s tau coefficient (τ) were calculated. A one-day lag in stem radius change was considered in correlation with soil water content. *** p < 0.001; ** p < 0.01; * p < 0.05.
