Stable Isotopes In Ecosystem Studies. The analysis of stable isotope ratios represents one of the most exciting new technical advances in environmental sciences. Using stable isotopes TSH scientists are able to capitalize on two essential attributes. 10 January 2000 Abstract Stable isotopes are a powerful research tool in environmental sciences and their use in ecosystem re-search is increasing. Indeed the use of stable isotopes to understand plant interactions which.
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. Stable isotope-based methods have proved to be immensely valuable for ecological studies ranging in focus from animal movements to species interactions and community structure. Variability in water isotopes is used to study sources of water to streams and rivers evaporation rates groundwater. The addition of stable isotopes SI of ¹³C and ¹⁵N has been used to study several aquatic processes thus avoiding environmental disturbance by the observer. Here we illustrate how stable isotopes of H C and O have been utilized to document changes in ecosystem structure and function using a case study from a subtropical savanna ecosystem. This approach employed for.

Indeed the use of stable isotopes to understand plant interactions which. First building on studies conducted in modern ecosystems this paper outlines key aspects of the stable isotope ecology of freshwater environments highlighting the importance of considering physical and biological processes associated with ancient biogeochemical cycles. Stable isotopes are a powerful research tool in environmental sciences and their use in ecosystem research is increasing. Here we illustrate how stable isotopes of H C and O have been utilized to document changes in ecosystem structure and function using a case study from a subtropical savanna ecosystem. The analysis of stable isotope ratios represents one of the most exciting new technical advances in environmental sciences. The ecological applications of stable isotopes have so far been mostly confined to physiological and ecosystem level studies.
