Yankuang ceshi, 2017 The stable isotope of carbon and nitrogen (δ13C and δ15N) in marine sediments have received much attention as they can be used to trace the sources of organic matter and are helpful in understanding the carbon cycle, climate change and the transformation

Seasonal changes in the δ13C and δ15N signatures of the Lago Maggiore pelagic food web
Journal of Limnology, 2011 Seasonal variation in the relative contributions of littoral and pelagic food sources to the diets of open-water zooplankton and subsequent changes in their trophic positions were investigated with carbon and nitrogen Stable Isotope Analysis (SIA).

Frontiers in Marine Science, 2021 The use of top-consumers as bioindicators of the health of food webs is hampered by uncertainties in their effective use of resources. In this study, the abundance of stable nitrogen isotopes in amino acids from homogenised eggs of the Yellow-legged Gull

The fate of nitrogen in the Zarin-Gol River receiving trout farm effluent
Scientific Reports, 2023 This study investigated the Zarrin-Gol River ecosystem in Iran to trace organic matter in the food web and evaluate the impact of aquaculture farm effluent using stable isotopes of nitrogen (δ15N) and carbon (δ13C).

Journal of Threatened Taxa, 2020 The penaeid shrimp Xiphopenaeus kroyeri is the second most important species of crustacean in Brazilian fisheries. Stable isotopes of carbon and nitrogen are chemical proxies to provide quantitative information about the consumer isotopic niche, which is

Measure of carbon and nitrogen stable isotope ratios in cultured cells [PDF]
Journal of the American Society for Mass Spectrometry, 2004 We report the measurement of the natural isotope ratios of nitrogen and carbon in subcellular volumes of individual cells among a population of cultured cells using a multi-isotope imaging mass spectrometer (MIMS), [MIMS is the prototype of the NanoSIMS 50, Cameca, France.] We also measured the nitrogen and carbon isotope ratio in cells after they had ...

Ecology and Evolution, 2021 When Pacific salmon (Oncorhynchus spp.) spawn and die, they deliver marine‐derived nutrient subsidies to freshwater and riparian ecosystems. These subsidies can alter the behavior, productivity, and abundance of recipient species and their habitats ...

Stable isotope ratios of nitrogen and carbon as biomarkers of a vegan diet
European Journal of Nutrition, 2022 Abstract Purpose Dietary biomarkers can potentially overcome the limitations of self-reported dietary data. While in ecology and archaeology, stable isotope ratios of carbon and nitrogen are widely used as biomarkers, this is not the case in nutrition research. Since the abundance of the 13C and the 15N isotope differ in
