In the lake from which the sediments were collected we measured between 57.3 and 163.0 g coarse organic matter m\textsuperscript{-2}, so the microcosms used in the experiment contained at most 40\% of the coarse organic matter of the lake. However in the microcosms all of the leaf litter was added to the surface of the sediments, while a portion of the leaf litter in the lakes was buried within the sediment.  \subsubsection{Dissolved Oxygen and Sediment Oxygen Demand}  In the litter experiment the dissolved oxygen concentration of the overlying water in the bottles ranged from 80.09 to 275.80 $\mu mols$ O\textsubscript{2} L\textsuperscript{-1} with a median mean ($\pm$ SD)  of 224.80 206.10 ($\pm$ 48.8)  $\mu mols$ O\textsubscript{2} L\textsuperscript{-1}. The dissolved oxygen concentration varied significantly over the course of the incubation (p < 0.0001) and was the lowest on the initial day of the incubation (Fig. \ref{fig:DO_days}). Additionally, the bottles containing leaf litter had significantly lower dissolved oxygen concentrations (p = 0.002) but this was only evident on day 0 and day 2 of the incubation (Fig. \ref{fig:DO_days}). During the litter experiment the temperature ranged between 23.4 and 25.5\textsuperscript{o} C and the oxygen consumption of the bottles ranged between 357 and 2098 $\mu mols$ O\textsubscript{2} m\textsuperscript{-2} h\textsuperscript{-1}, with a median mean ($\pm$ SD)  flux of 920 1020.0 ($\pm$ 388.7)  $\mu mols$ O\textsubscript{2} m\textsuperscript{-2} h\textsuperscript{-1}. Since the treatments with added leaf litter had more organic matter in the sediments than those without leaf litter, we normalized the oxygen flux to the estimated organic matter content of the sediments in the bottles. The organic matter normalized oxygen flux ranged from 7.34 to 42.54 $\mu mols$ O\textsubscript{2} (g organic matter)\textsuperscript{-1} h\textsuperscript{-1}, with a median flux of 18.97 $\mu mols$ O\textsubscript{2} (g organic matter)\textsuperscript{-1} h\textsuperscript{-1}. The only factor that affected organic matter normalized oxygen flux in the litter experiment was the presence of leaf litter in the bottles (Table \ref{tab:SOD_ANOVA}). Bottles containing leaf litter had a mean oxygen flux of 23.85 $\mu mols$ O\textsubscript{2} (g organic matter)\textsuperscript{-1} h\textsuperscript{-1}, which was significantly greater than the mean oxygen flux of 17.67 $\mu mols$ O\textsubscript{2} (g organic matter)\textsuperscript{-1} h\textsuperscript{-1} in the bottles without leaf litter (Fig. \ref{fig:sod}). There was no significant interaction between the presence of leaf litter and the duration of the experiment (Table \ref{tab:SOD_ANOVA}) but the lack of any difference in oxygen flux on day 21 (Fig \ref{fig:sod}) might suggest that the difference in oxygen flux between the bottles with and without leaf litter was temporary.
