Figure 1.
Mean initial and final C:N ratio of Alternanthera and Eragrostis litter decomposing both alone and in mixture.
Means ±1 SE are shown.
Figure 2.
Remaining mass (% initial) of native and invasive plant litter when each of them was decomposing alone (a) or in mixtures (b).
Dynamics of litter mass remaining between single-species and litter mixtures within Alternanthera and Eragrostis were presented in (c) and (d), respectively. Asterisks indicate time points when means were significantly different at α = 0.05.
Table 1.
ANOVAs for remaining litter mass as affected by species and litter mixing with time in the field incubation study.

Litter mass decay constants (k, month-1) during litter decomposition in single- (kalone) or mixed-species litterbags (kmixed) after 8 months of decomposition in the field.
Table 3.
Expected and observed litter mass remaining (g) in mixed-species litter bags after field incubation for 3, 6 and 8 months.
