Fig. 6

A log-log plot of branchwood diameter and SVR, which were measured independently. Data points represent the species average for each experimental size class, and each shape depicts one species. Colors equate to the experimental fuel classes, from 0–2 mm (1 h, light orange) to 21.1–26 mm (10 h, dark purple). Linear least squares fit of the log transformed data resulted in \(r^{2}=0.91\) and \(p < 2.2e-16\)
