Web11 apr. 2024 · These measurements were made on at least four different plants of each species. On a few different leaves of each species, the responses of stomatal conductance, photosynthesis, and PS II chlorophyll fluorescence to CO 2 concentrations from 100 to 1200 μmol mol −1 were determined. There were nine steps of CO 2 (400, 300, 200, 100, 400, … Web9 mei 2024 · Between low and mid-tide the magnitude of the vessel generated shear stress varies widely and, thus, is a function of vessel operations. This range of water depths coincide with the region of maximum tidal currents, and at Station 1 the vessel wake stress can easily exceed the current stress until the marsh platform is submerged.
