Abstract

Biomarkers, due to their structure and biochemistry, are resistant to soil degradation and mineralization under particular environmental conditions, and therefore can provide molecular evidence of paleobiota and past land vegetation, and of the intensity of not only modern, but also past biochemical processes in the biosphere. Parameters of the humus group composition, optical densities of solutions of humic acids, pool of chlorophyll, lipids, fatty acids, and lignin phenols together with the isotopic composition of organic carbon and soil age are suggested as promising biomarkers for paleoecological studies.

土壤生物标志物作为俄罗斯平原景观演变的指标

摘要

生物标记物由于其结构和生物化学特性，在特定的环境条件下能够抵抗土壤退化和矿化作用，因此可以提供古生物群和过去土地植被的分子证据，以及现代生物过程和过去生物化学过程的强度。生物圈。腐殖质族组成的参数，腐殖酸溶液的光密度，叶绿素，脂质，脂肪酸和木质素酚的集合以及有机碳的同位素组成和土壤年龄被认为是古生态学研究的有前途的生物标记。
