Abstract

Biogeochemical coefficients calculated on the basis of the total and mobile element contents were applied to evaluate biogenic migration of a wide range of microelements with different biophilicity (Ti, Fe, Mn, Cr, Co, Ni, Cu, Zn, Zr, Sr, Pb, Cd) in the “plant-soil” system. The study object is a forested landscape-geochemical catena formed on a uniform loamy lithology and located in the southern part of the core area in the Central Forest Nature Reserve (the Tver' Region, NW Russia). The obtained results indicate that in the analyzed reference forest communities tree species play the major role in the uptake and turnover of biophilic microelements (Mn, Zn, Co) while sphagnum moss and grassy covers mostly absorb the elements with low biophilicity (Fe, Ti, Cr, Zr, Pb).

Keywords

catena, total element content, plant available forms of metals, coniferous-broadleaf communities, southern taiga spruce forests, biogeochemical ac-tivity of plant species.
