Statistical analysis
We examined the differences in V max between the
leaf litter of tree species using pairwise Welch’s t -test (Welch
1947) using the variance of these coefficients estimated with thenls function. In this test, alpha level for significance
(p < 0.05) was adjusted using the Bonferroni
correction. We examined the effects of leaf litter elemental contents
and ratios on V max (or
Max-VE ) and TRA using least-squared linear
regression analyses.
