“…Wheeler & Björn -säter 1992), and comparable to some seaweeds from coral reefs (e.g. Schaffelke & Klumpp 1998, Lapointe et al 2005, Tsai et al 2005. These ranges of tissue phosphorus values are smaller than the ranges in seawater phosphate concentrations (3.43-fold) and phosphate uptake rates at 5 μM, which varied from 2.88-fold in P. lucida to 10.94-fold in Melanthalia abscissa.…”

High in situ rates of phosphate uptake should coincide with high tissue phosphorus content and/or high growth rate and be either supply-driven (largely controlled by the phosphate concentration in the surrounding seawater) or demand-driven (largely dictated by the maximum uptake rate, V max , and under the control of the organism). To test this hypothesis, 6 common New Zealand seaweed species (Cystophora torulosa, Melanthalia abscissa, Pterocladia lucida, Ulva intestinalis, Xiphophora chondrophylla and Zonaria turneriana) were used. We calculated in situ rates of phosphate uptake from the kinetic constants of uptake, monthly rates of uptake at a fixed phosphate concentration and seawater phosphate concentration, and compared these rates with monthly tissue phosphorus content. There were no significant differences in the half-saturation constant (K m ) values for phosphate uptake by the 6 species. V max and affinity (V max /K m ) were largely a function of the seaweed surface area:volume quotient. In the 5 species where there was a peak in tissue phosphorus levels, it occurred in July or September/October. Peaks in tissue phosphorus in M. abscissa, P. lucida, U. intestinalis and Z. turneriana coincided with, or occurred soon after, peaks in calculated in situ rates of phosphate uptake. Maximum rates of in situ phosphate uptake were demand-driven in all subtidal species and supply-driven in the only intertidal alga U. intestinalis.

“…Production may also be severely limited by low temperatures [29]. Under the conditions of nutrient-enriched seawater cultivation, the daily SGR of G. coronopifolia was positively correlated with temperature ranging from 15 to 35°C, reaching a maximum production rate at 30°C [30]. The favorable temperature for G. lemaneiformis growth ranged from 12 to 23°C.…”

Increased nutrient inputs to temperate coastal waters have led to increased occurrences of macroalgal blooms worldwide. To identify nutrients that are limiting to macroalgae and to determine whether different forms of these nutrients and long-term ambient nutrient conditions affect macroalgal response, we used in situ enrichment methods and tested the response of 2 bloom-forming species of macroalgae, Ulva lactuca and Gracilaria tikvahiae, from shallow estuaries of Waquoit Bay, Massachusetts, USA, that receive different land-derived N inputs. We enriched caged macroalgal fronds with nitrate, ammonium, phosphate, and N + P combinations, and measured growth, nutrient content, and δ 15 N signatures of fronds after 2 wk of incubation. In these estuaries, P did not limit growth, however, the 2 species differed in growth response to N additions. Growth of U. lactuca was greater in Childs River (CR), the estuary with higher nitrate inputs, than in Sage Lot Pond (SLP); growth in SLP increased with nitrate and ammonium enrichment. In contrast, growth of G. tikvahiae was greater in SLP than in CR, but had no growth response to N enrichment in either site. C and N contents differed initially between species and sites, and after nutrient enrichment. Final tissue % N increased and C:N decreased after nitrate and ammonium enrichment. δ 15 N values of the macroalgae demonstrated uptake of the experimental fertilizers, and a higher affinity and faster turnover of internal N pools with ammonium than nitrate enrichment in both species. We suggest that U. lactuca blooms in areas with both high nitrate and ammonium water column concentrations, and is more N-limited in oligotrophic waters where DIN levels are too low to sustain high growth rates. G. tikvahiae has a greater N storage capacity than U. lactuca, which may allow it to grow in less nutrientrich waters.
