- Abstract
- Receiving coastal waters and estuaries are among the most nutrient-enriched environments on
earth, and one of the symptoms of the resulting eutrophication is the proliferation of opportunistic, fast-growing marine seaweeds. Here, we used a widespread macroalga often involved in
blooms, Ulva spp., to investigate how supply of nitrogen (N) and phosphorus (P), the two main
potential growth-limiting nutrients, influence macroalgal growth in temperate and tropical
coastal waters ranging from low- to high-nutrient supplies. We carried out N and P enrichment
field experiments on Ulva spp. in seven coastal systems, with one of these systems represented
by three different subestuaries, for a total of nine sites. We showed that rate of growth of Ulva
spp. was directly correlated to annual dissolved inorganic nitrogen (DIN) concentrations, where
growth increased with increasing DIN concentration. Internal N pools of macroalgal fronds were
also linked to increased DIN supply, and algal growth rates were tightly coupled to these
internal N pools. The increases in DIN appeared to be related to greater inputs of wastewater to
these coastal waters as indicated by high d
15
N signatures of the algae as DIN increased. N and P
enrichment experiments showed that rate of macroalgal growth was controlled by supply of DIN
where ambient DIN concentrations were low, and by P where DIN concentrations were higher,
regardless of latitude or geographic setting. These results suggest that understanding the basis
for macroalgal blooms, and management of these harmful phenomena, will require information
as to nutrient sources, and actions to reduce supply of N and P in coastal waters concerned. (literal)
