Figure 2


Fig. 2. O2 flux determined from O2 profiles at the upstream location (filled symbols) and downstream locations (open symbols) of Vallisneria spiralis (circles) and Vallisneria americana in a flat (squares) and twisted configuration (triangles) at (A) 17.1 mmol m–3 CO2 and (B) 1.71 mmol m–3 CO2. Solid lines are model fits for V. spiralis, dash-dotted lines are for V. americana in a flat configuration, and the broken lines are for V. americana in a twisted configuration. Thick lines fit the model data at the upstream location and the thin lines are fit to the downstream location. Note that for Fig. 1B, the models at the leading edge overlap. The two horizontal dotted lines indicate the range of O2 fluxes determined from V. americana at ~0.171 mmol m–3 CO2 (Nishihara and Ackerman, 2006). Values are means ± s.e.m. In A, N=6 for V. spiralis, N=6 for V. americana in the flat configuration and N=8 for V. americana in the twisted configuration. In B, N=9 for V. spiralis and N=6 for V. americana in the flat configuration.
