A NOTE ON THE GREATLY REDUCED ABILITY OF FUCUS VESICULOSUS TO ABSORB OR EVOLVE CO2 WHEN NOT SUBMERGED

Abstract

The rockweed, F. vesiculosus, inhabits the littoral zone and is exposed for a large part of the time between tides. It is shown that this weed fixes or evolves CO2 at a greatly reduced rate when exposed, even if its surface is wet and the atmosphere surrounding it is saturated with water.
