METHOD OF ASSESSMENT OF FUNCTIONAL STRUCTURE OF SOIL POPULATION BY isotope ratio mass spectrometry analysis

摘要

A method of evaluating the functional structure of the soil population comprising determining the isotopic composition of carbon (sootnoshenieS / C, expressed in terms δS) and nitrogen (sootnoshenieN / N, expressed in terms of δN) in soil animal tissues via mass spectrometric analysis, characterized in that the total range of variation δN δS quantities and in tissues of animals soil different trophic levels taken equal to 12% and 6%, respectively; to separate pasture and detrital food chains used carbon isotope composition (δS); community to assess the stability of the functional structure used intraspecific dispersion of the isotopic composition of carbon and nitrogen in the soil tissues of animals.
