Non-additive effects on litter decomposition were observed of the litter mixtures composed of mangrove species. The water nutrient content, the initial trait dissimilarity, and the CWM of litter mixtures varied with species composition.
3.1 Decomposition rate (k) and mass
remaining
Non-additive effect on litter decomposition was detected in the litter
mixtures from mangrove species, but not in the mixture of A.
corniculatum vs. S. alterniflora (Fig. 1a, b). The observed mass
remaining of the mixture of A. corniculatum vs. K obovatawas substantially higher than the expected value, whereas the observed
mass remaining of the mixture of A. corniculatum vs. A.
marina was lower than the expected one (p < 0.05),
only the mixture of A. corniculatum vs. S. alterniflora did not show significant difference between the observed and the
expected values (p > 0.05; Fig. 1b).
