The use of stable isotopes to solve biogeochemical problems in ecosystem analysis is increasing rapidly because stable isotope data can contribute both source-sink (tracer) and process information: The elements C, N, S, H, and all have more than one isotope, and isotopic compositions of natural materials can be measured with great precision with a mass spectrometer. Isotopic compositions change in predictable ways as elements cycle through the biosphere. These changes have been exploited by… Expand
Tracing energy flow in stream food webs using stable isotopes of hydrogen
TLDR
Consistent source separation in streams suggests that δD may provide a complementary food web tracer to δ13C in aquatic food webs, and Lack of significant seasonal or spatial variation inδD is a distinct advantage over δ 13C for applications in many aquatic ecosystems. Expand

Stable isotope partitioning in seep and vent organisms: chemical and ecological significance
TLDR
Stable isotope compositions provide insight into these diverse metabolic strategies; however, a complete inventory of the concentration and isotopic composition of inorganic and organic substrates, as well as supporting biochemical, enzymatic and observational studies, are needed to resolve fundamental ecological questions.

TLDR
Stable isotope ecology and patterns of stable isotope fractionation during organic matter decomposition are considered with special emphasis on the fractionation of isotopes in food chains and the use ofstable isotope studies of trophic relationships between soil animals in the field. Expand
Expanding the Isotopic Toolbox: Applications of Hydrogen and Oxygen Stable Isotope Ratios to Food Web Studies
TLDR
The advantages and challenges associated with three applications of δ2H and δ18O values in food web studies are explored, and directions for targeted research are highlighted that will increase understanding of how these markers move through food webs and reflect ecological processes. Expand
Stable isotopes as tracers in aquatic ecosystems
The addition of stable isotopes (SI) of 13 C and 15 N has been used to study several aquatic processes, thus avoiding environmental disturbance by the observer. This approach, employed for the lastExpand

TLDR
Investigation of carbon isotope fractionation in a variety of photosynthetic and nonphotosynthetic organisms, including some grown in the laboratory under controlled conditions and some that had grown in a natural environment finds the effect of isotopic substitution on the physicochemical properties of molecules interesting.
