In waterfowl exclosures, Prevost et al. Attaway et al. All these figures are much higher than those found in four seagrasses collected nearby. With the possible exception of K, these nutrients are generally in greater concentrations in aboveground parts. His experiments suggested that leaves are the major nutrient sink in wigeongrass and that water-column nutrients are used through the leaves.
Little information is available for the minor nutrients.
The elemental composition of wigeongrass is shown in Table 3 . In sufficient quantities, these two elements are potentially toxic to waterfowl. In summary, available information on the chemical composition of wigeongrass provides few clues about why the plant is such an important waterfowl food. Perhaps the delicate texture of wigeongrass leaves and stems adds to the plants palatability. Very little is known about the chemical composition of wigeongrass drupelets.
