Study shows some aquatic plants depend on the landscape for photosynthesis

ASU researchers found that not only are freshwater aquatic plants affected by climate, they are also shaped by the surrounding landscape. When in an environment where CO2 is limited, aquatic plants use strategies to extract carbon from bicarbonate. Scientists identified patterns across ecoregions around the globe and discovered a direct link between the availability of catchment bicarbonate and the ability of aquatic plants to extract carbon from that bicarbonate.
