Fauna and flora horizontal microeconom in aquatic and terrestrial ecosystems

Korlyakov K. A.  (candidate of biology, docent, FSBEI "Chelyabinsk State University")

Microbiocenoses of soils and bottom sediments bordering on artificial substrates (curbs, concrete slabs, pillars) were studied. In the soils, an increased number of bacteria, fungi and algae was found in the marginal areas. In the bottom sediments near the edge of the silt, bacteria also dominated. The edges of the sludge was dominated by colonial forms of algae, while in the distance the brim – trichomania form. Also, crustaceans and large protozoa predominated in the marginal areas of the silt, and nematodes predominated in the distance of the edges. In the horizontal section of the soil at a distance from artificial substrates, the ecotonic geochemical effect was observed at a distance of 5-10 cm, where the concentrations of phosphates and nitrites decreased. Thus, in the marginal areas, more oxidizing conditions are formed, in addition, spores of microorganisms are washed into these areas by wind and currents, forming a kind of pool.

Keywords:bacteria, algae, soil, silt, abundance, ecotone.
