Abstract
Ratios of photosynthetic pigment concentrations in aquatic macrophytes can provide a useful way to differentiate between inputs of emergent versus submergent macrophytes into aquatic food webs. Using reversed-phase HPLC we examined the distribution of carotenoid and chlorophyll pigment markers in eight macrophytes from the tidal freshwater portion of the Hudson River. Lutein was the most abundant carotenoid in all macrophytes, and concentrations in the emergent forms were significantly higher. Chlorophyll-b showed significantly higher concentrations in the submerged macrophytes than in the emergent forms. The chlorophyll-b/lutein ratio may be a useful marker to distinguish between organic inputs of submergent and emergent forms of macrophytes in aquatic ecosystems.
