Values are LS means ± SE
†Data were analyzed on a transformed scale and LS means are provided on the original scale in parenthesis. Box–Cox transformation technique was used to identify the optimal data transformation, where needed. ANOVA followed by Tukey’s HSD post hoc comparisons, where appropriate
*Significant main effects of site (p < 0.05)
a,b,c LS means for sites sharing the same letter are not significantly different
