Stable isotope views on ecosystem function challenging or. among species in the ecosystem can be quantified using stable isotopic techniques. Stable nitrogen isotopes can be used for tracking of pollutant derived from urban effluent or other anthropogenic sources that contribute to eutrophication and other management issues in aquatic environment. Analysis of non-radioactive, naturally occurring carbon and nitrogen isotopes is one of the most powerful, The use of N and C stable isotopes is especially well suited to this study because of the predictable manner in which both elements can reflect trophic position, and because of the importance of nitrogen in ecosystem development (Boring et al., 1988)..

Salmon nutrients, nitrogen isotopes and coastal forests The yearly return of salmon from the open Pacific Ocean to coastal waters of West-ern North America is one of nature’s grand displays and recent investigations by research-ers in Washington, British Columbia and Alaska indicate that the signature of salmon finds its way into both aquatic and terrestrial ecosystems, as far inland as the The stable isotopes of carbon, nitrogen, oxygen, hydrogen, and sulfur are mostly commonly used in ecological, biological and hydrological studies. As improved and new isotopic techniques evolve, it becomes less time consuming, cheaper and requires smaller sample sizes.

In the past 20 years, rapid progress in stable isotope (SI) studies has allowed scientists to observe natural ecosystems from entirely new perspectives. Stable isotopes distributions in natural systems reflect an integrated history of physical and metabolic processes within ecosystems and are very useful for a wide variety of ecosystem studies. This review provided information on how stable isotopes can be used to various aspects of ecological research. The discussion is limited to applications of some selected isotopes. Additional
