Fig. 1

Pith-to-bark radial trend in breast-height wood density. Black dots correspond to mean densities by five-ring group at each site. The black lines show the density predicted by model 1 for an average site (middle solid line, L = 0) and for sites at the 5th and 95th percentiles (lower and upper dashed lines, L = −34.6 and L = +34.6, respectively)
