Food webs in forest and pasture streams in the Waikato region, New Zealand: A study based on analyses of stable isotopes of carbon and nitrogen, and fish gut contents [PDF]
Stable isotopes of carbon (C) and nitrogen (N) were studied in 11 stream communities in the Waikato region of New Zealand. From comparisons of mean d13C and d15N values, food webs in the shaded, forest streams were clearly based on allochthonous material

Stable carbon isotopes in human tissues
Nature, 1978ON studying the distribution of 14C from nuclear weapon tests in a wide range of human tissues, it was observed that significant modification of 14C/12C isotopic ratio had occurred, largely as a function of variable carbon renewal rates1,2. As a parallel exercise, 13C/12C isotope ratios have been assayed, 13C and 12C being the nonradioactive isotopes ...

Mercury and Stable Isotopes of Carbon and Nitrogen in Mink
Environmental Toxicology and Chemistry, 2007Abstract Total Hg concentrations and values of stable isotopes (δ15N, δ13C) in tissues of mink (Mustela vison) captured in Rhode Island (USA) during winters of 1999 to 2004 were statistically distinct based on location. Mink captured in salt marsh environments (salt marsh group mink [SMGM]) had significantly lower mean Hg concentrations ...

The separation of stable isotopes of carbon
Russian Chemical Reviews, 1989The present state of work on the separation of carbon isotopes by diffusion, fractional distillation, chemical isotopic exchange, and the selective excitation and dissociation of molecules in electrical discharges or in the field of laser radiation has been examined.

Stable Carbon and Nitrogen Isotopic
Aquatic Geochemistry, 2004The perennially ice-covered lakes in the McMurdo Dry Valleys, Antarctica, are part of the coldest and driest ecosystem on earth. To understand lacustrine carbon and nitrogen cycling in this end-member ecosystem, and to define paleolimnological proxies for ice-covered lakes, we measured the stable carbon and nitrogen isotopic composition of particulate ...

Carbon stable isotopes as indicators of coastal eutrophication
Ecological Applications, 2014Coastal ecologists and managers have frequently used nitrogen stable isotopes (δ15N) to trace and monitor sources of anthropogenic nitrogen (N) in coastal ecosystems. However, the interpretation of δ15N data can often be challenging, as the isotope values fractionate substantially due to preferential retention and uptake by biota.
