ANOVA model results for computer-aided tomography (CT) estimates of coarse root abundances (0–10 cm), coarse root volumes (0–30 cm), and coarse root diameters with significant (P < 0.05) main effects of elevation.

Means ±standard error (SE) are shown for each. Significant sediment X elevation interactions are indicated with an asterisk. Main effects of sediment are indicated. Means with different letters are significantly different (P < 0.05), ns is non-significant.
