and strength of the non-additive effect indicated by O-E (Observed –
Expected mass remaining). The asterisk is presenting a significant
deviation from zero (p < 0.05), while n.s means no
significant
deviation.
3.2 Nutrient content in water after
decomposition
There was no difference in total N in water between the observed and
expected values of all litter mixtures (Fig. 3b), but for total P, the
observed content lower than the expected value was found in the mangrove
litter mixtures (Fig. 3c). Among litter mixtures of the observed values, A. corniculatum vs. K. obovata were lower in all nutrients
than A. corniculatum vs. A. marina (significantly) and A. corniculatum vs. S . alterniflora (slightly)
(Fig. 3).
