Webinterested in using stable isotope analysis (SIA). Ratios of stable isotopes of carbon (13C/12C), nitrogen (15N/14N), and sulphur (34S/32S) differ among various substances, and allow for dietary inferences to be made due to the predictability of isotopic relationships between consumers and their food. WebThe values of natural abundance of stable isotopes were measured in 13 micronekton fish species sampled during the BATHYPELAGIC cruise (North Atlantic, June 2024). This dataset contains the values obtained for carbon and nitrogen in bulk tissues, and nitrogen values in amino acids.

WebJun 6, 2005 · Stable isotope analysis can provide a useful tool for determining time-integrated measures of proportional food source contributions to fish diets. Ratios of stable (non-radioactive) isotopes of common elements (e.g., C,N,S) vary among food sources, and tissues of consumers (e.g., fish) reflect the isotopic ratios of their diet. For isotopic … WebOne of the most important applications of nitrogen stable isotopes is its ability to determine the trophic level of a species.

WebMay 28, 2024 · In this study, nitrogen stable isotopes (δ 15 N) in fish are evaluated as indicators of environmental changes in south Florida wetlands. Stable nitrogen isotope (δ 15 N) data of select fish species and water quality collected from the Florida Everglades between the 1990s and 2000s were used to assess the relationship between total … WebMay 1, 2024 · Section snippets Isotope data.
