“…The chemical composition of algae and plants is directly influenced by environmental conditions of the site where they live (Kamer et al, 2004;Larcher, 2000), especially the availability of inorganic nutrients and light. On the other hand, the abiotic conditions seem to be less influential on animals: the chemical composition of invertebrates and vertebrates is more influenced by biological factors, such as diet, stage of life and reproductive cycle (Ogawa & Maia, 1999).…”

“…The chemical composition of primary producers, such as algae and plants, seems to be more directly influenced by the environmental conditions in which they are inserted (e.g., Kamer et al, 2004;Frankovich et al, 2009), in particular by abiotic factors, such as the availability of light and dissolved inorganic nutrients (e.g., nitrate, phosphate). However, the environment does not affect marine animals exactly in the same way.…”

ABSTRACT. The chemical profiles of Desmapsamma anchorata, Hymeniacidon heliophila (Porifera), Bunodosoma caissarum, Renilla muelleri (Cnidaria), Aplysia brasiliana, Eledone massyae, Isognomon bicolor (Mollusca), Echinaster brasiliensis, Echinometra lucunter, Holothuria grisea, Lytechinus variegatus (Echinodermata), and Phallusia nigra (Chordata) were determined. Hydrosoluble protein was the most abundant class of substances for all species, except for the ascidian Phallusia nigra, in which the carbohydrate content was higher. The percentages of hydrosoluble protein (dry weight, dw) varied widely among the invertebrates, ranging from 5.88% (R. muelleri) to 47.6% (Eledone massyae) of the dw .The carbohydrate content fluctuated from 1.3% (R. muelleri) to 18.4% (Aplysia brasiliana) of the dw. For most of the species, lipid was the second most abundant class of substances, varying from 2.8% (R. muelleri) to 25.3% (Echinaster brasiliensis) of the dw. Wide variations were also found for the invertebrates nitrogen content, with the lowest value recorded in the cnidarian R. muelleri (2.02% of the dw) and the highest in the molluscan E. massyae (12.7% of the dw). The phosphorus content of the dw varyed from 0.24% (R. muelleri) to 1.16% (E. massyae). The amino acid composition varied largely among the species, but for most of the species glycine, arginine, glutamic acid, and aspartic acid were the most abundant amino acids, with histidine and tyrosine among the less abundant amino acids. The actual content of total protein in the samples was calculated by the sum of amino acid residues, establishing dw values that fluctuated from 11.1% (R. muelleri) to 66.7% (E. massyae). The proteinaceous nitrogen content was high in all species, with an average value of 97.3% of the total nitrogen. From data of total amino acid residues and total nitrogen, specific nitrogen-to-protein conversion factors were calculated for each species. The nitrogen-to-protein conversion factors ranged from 5.10 to 6.15, with an overall average of 5.45. The use of the specific nitrogen-to-protein conversion factors established here is recommended, since it would yield more accurate determinations of total protein in the species tested in this study. Keywords: nitrogen-to-protein conversion factors, total protein, amino acid composition, lipid, carbohydrate, tropical Atlantic.

“…Distinguishing nitrogen sources is not only necessary to understand the biogeochemical cycle in coasts and estuaries but also important to establish effective coastal environmental management policies (Rogers, 2003;Kamer et al, 2004). Nitrogen stable isotope ratio (δ 15 N) has been successfully applied to trace nitrogen sources over the last decade, depending on their specific signatures (McClelland and Valiela, 1998;Savage and Elmgren, 2004;Ochoa-Izaguirre and Soto-Jiménez, 2013;Viana and Bode, 2015).…”

• 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.
