A review of the literature shows that seagrass growth, abundance and morphology are
strongly linked to available nutrient resources. In north temperate climates and in habitats
with terrigenous sediments, nitrogen limitation occurs in both intertidal and subtidal beds.
Typically, seagrasses growing in terrigenous sediments have ample phosphorus but lack
nitrogen, and the plants' chemical composition is depleted in nitrogen. However, seagrasses
occurring in tropical environments and carbonate sediments appear to experience …
