“…This supposition get support from results of Han and Liu (2014) which stated that growth of macroalgae at S1, S3 and S4 were affected by PO 4 -P concentration. Impacts of metabolism to nitrogen and carbon in macrogalgae are species-specific owing to different storage capacity and nutrient requirements for growth (Hanisak and Harlin, 1978;Larned, 1998;Deutsch and Voss, 2006). The higher TN of algal tissue of Rhodophyta and Chlorophyta species compared to Phaeophyta species at the four sites along the Yantai coast showed different nitrogen storage between phyla.…”

• Yantai coast was affected by three types of DIN sources.• Macroalgal species suitable or not for DIN source tracing were suggested; • TN and δ 15 N were affected by nutrient concentrations and the metabolic factors.• P instead of N limited the tissue N uptake in low nutrient concentration sites. G R A P H I C A L A B S T R A C Ta b s t r a c t a r t i c l e i n f o To determine the dominant nitrogen sources and select effective macroalgal species for monitoring eutrophication along the Yantai coast, the total carbon (TOC), total nitrogen (TN) and nitrogen stable isotope ratio (δ 15 N) in macroalgal tissue were analyzed in conjunction with environmental variables in seawater along the Yantai coastline. The ranges of macroalgal tissue δ 15 N values together with dissolved inorganic nitrogen (DIN) composition indicated that except for the atmospheric deposition, there were three dominant types of nitrogen sources along the Yantai coast, with the agricultural fertilizer usage and factorial wastewater input at the S1 (Zhifu Island coast), the sewage discharge at S2 (the Moon Bay coast), the sewage discharge together with aquaculture impacts at S3 (Fisherman Wharf coast) and S4 (the Horse Island coast). Macroalgal growth were not limited by DIN but limited by P at S2, S3 and S4. Macroalgal species suitable or not for DIN source tracing along the Yantai coast were discussed. For sites with low DIN concentration, many species of three phyla could be used for DIN sources tracing with Laurencia okamurai, Gloiopeltis furcata and Ulva pertusa being ideal species. For site with high DIN concentration, however, species of Rhodophyta were not suitable and only Scytosiphon lomentaria and Monostroma nitidium were chosen.

“…Similar experimental data for nitrate uptake by Z. marina were not available, so parameters for nitrate were assumed to be the same as for ammonium. While many phytoplankton and marine macrophytes show some preference for ammonium, such differences are not great (Eppley et al 1969, MacIssac & Dugdale 1969, D'Elia & DeBoer 1978, Haines & Wheeler 1978, Hanisak & Harlin 1978.…”

A numerical model of nitrogen uptake and growth was developed for the temperate seagrass Zostera marina L. Goals were to evaluate the relative effects of light and nitrogen availability on nitrogen uptake and partitioning between leaf and root tissue. and to estimate nitrogen concentrations in the s e d m e n t and water column required to saturate growth. Steady-state predichons are quite robust with respect to a range of parameter values justified by available data The calculations indicated that roots are probably more important in overall nitrogen acquisition in most light and nitrogen environments encountered in situ, but may contribute less than 50 '/o of the total uptake in low light. The model also predcted amnlonium to be a much more important source of nitrogen than nitrate Nitrogen concentrahons required to saturate growth (even for nitrate) were estimated to be at least 50 % below concentrations commonly reported in situ, an indicat~on that nitrogen limitation of 2. marina is probably very rare in nature.

“…Differences between in situ and lab-· oratory estimates may be expected because of differ-ences in nutritional histories of the plants, and environmental factors which may limit growth or metabolic processes (e. g.

The uptake rates and critical tissue concentrations of nitrogen and phosphorus were determined for Chaetomorpha !inurn and Ulva rigida, the dominant algae in Peel Inlet, Western Australia. Both species had ratesaturating mechanisms of phosphate uptake described by Michaelis-Menten type functions; C. !inurn had the faster uptake rate (667 c. f. 272Jlg P g dwC 1 h-1 ) although U. rigida had a lower half-saturation value. Both species displayed linear relationships between ammonium uptake rates and substrate concentrations with C. !inurn having the greater slope (4.4 c. f. 1.7). Chaetomorpha !inurn also had a linear increase in uptake rate with increasing concentration of nitrate, but U. rigida showed rate-saturating kinetics; below 750 Jlg L -1 , U. rigida had the higher rate of uptake. Ulva rigida had critical tissue nitrogen and phosphorus concentrations of 20 and 0.25 mg g dwC 1 respectively. Corresponding concentrations for C. !inurn were 12 and 0.5 mg g dwC 1 • Ulva is frequently nitrogen limited during spring in Peel Inlet, reflecting the high nitrogen requirements of this plant compared to Chaetomorpha as well as the reduced ability of Ulva to store nutrients over winter. The growth rate of Ulva is negative in winter due to low salinity, temperature and irradience, and this results in negligible biomass at the time of highest inorganic nitrogen concentration. Chaetomorpha !inurn persists over winter allowing it to take advantage of elevated nutrient concentrations at the time; nutrients stored during winter support high growth rates in summer. The maximum tissue nitrogen levels recorded for Ulva were only 47% higher than the critical concentration while maximum tissue phosphorus concentration was almost 9 times the critical level. This seasonal limitation by nitrogen supports an earlier hypothesis that production in the system may be nitrogen limited in summer. It was concluded that differences in nutrient requirements and aquisition strategies afforded C. !inurn greater competitive potential for utilizing the seasonal and short-term increases in nutrient concentrations that occur in Peel Inlet.
