Research is devoted to using chemical markers for studying and description of ecosystems. Photosynthetic
pigments – carotenoids and chlorophylls, and soil polymers – humic, fulvic acids and their salts, were used as
chemical markers. Correlations between concentrations of these markers in samples and parameters of “total
nitrogen” and ash were studied. Complex chemical analysis for nine samples collected on a Demaria hill in
the altitude range from 47 m to 408 m above see level was carried. It was concluded that in meager antarcticlike
ecosystems the content of carotenoids and chlorophylls adequately reflects the quantity of a whole
phytomass and of biomass. Total content humic and fulvic acids can be used to estimate quantity of organic
substances in soils. Comparison of photosynthetic pigment concentrations with “total nitrogen” parameter
allows to separate biogenic phytomass nitrogen and animal waste products.
