Stable δ15N and δ13C isotope ratios in aquatic ecosystems
In the past 20 years, rapid progress in stable isotope (SI) studies has allowed scientists to observe natural ecosystems from entirely new perspectives. This report addresses the fundamental concepts underlying the use of the SI ratio. The unique characteristics of the SI ratio make it an interdisciplinary parameter that acts as a chemical fingerprint of biogenic substances and provides a key t...
متن کاملSample acidification significantly alters stable isotope ratios of sulfur in aquatic plants and animals
Sulfur stable isotopes are increasingly being used as tracers of material processing in studies of both modern and historical food webs. Preparation of plant and animal material for isotope analysis routinely includes steps that remove inorganic material not normally assimilated by consumers. Whereas acidification of samples is known to assist with this for some elements (carbon), it can produc...
متن کاملA multi-stable isotope framework to understand eutrophication in aquatic ecosystems.
Eutrophication is a globally significant challenge facing aquatic ecosystems, associated with human induced enrichment of these ecosystems with nitrogen (N) and phosphorus (P). However, the limited availability of inherent labels for P and N has constrained understanding of the triggers for eutrophication in natural ecosystems and appropriate targeting of management responses. This paper propos...
متن کاملCorrection: Equations for Lipid Normalization of Carbon Stable Isotope Ratios in Aquatic Bird Eggs
Stable isotope ratios are biogeochemical tracers that can be used to determine the source of nutrients and contaminants in avian eggs. However, the interpretation of stable carbon ratios in lipid-rich eggs is complicated because (13)C is depleted in lipids. Variation in (13)C abundance can therefore be obscured by variation in percent lipids. Past attempts to establish an algebraic equation to ...
متن کاملProgress of Rural Aquatic Ecosystem Analysis using Stable Isotope Ratios in Japan
Land improvements in Japan involve the need to conserve ecosystems and biodiversity, hence research and research methods related to ecosystem conservation in rural aquatic areas are increasing and developing. Analysis in rural aquatic ecosystems using stable carbon and nitrogen isotope ratios is an important research method and such isotope ratios are used for various purposes when investigatin...
