Syshchykova O. Ecological features of species diversity of streptomycetes associations in technogenic edatopes

Dissertation is devoted research of different on mobility heavy metals forms accumulation and their influence on streptomycetes associations' structural organization in the technogenic broken soils, that results in formation of streptomycetes specific associations, which differ from the complexes of natural ecosystems. Use the sorbents the heavy metals mobility and bioavailability. On the basis of determination of Berger-Parker, Margalef and Serensen indexes, is set positive sorbents influence on renewal of both streptomycetes specific variety and quantity. In model experiments is set the heavy metals negative influence on quantity of streptomycetes associations, that at maximal toxicants concentration results in irreversible violation of cenosis homoeostasis. It is well-proven that at the heavy metals increasing concentrations action there is narrowing of streptomycetes specific spectrum and decline of variety indexes due to sensible forms death and increase of resistant species relative amount, apt at the toxicants accumulation in aerial mycelium. It is first well-proven that in technozems of tailing ponds dikes quantity and variety of streptomycetes cenosis is increased depending on phytocenosis composition: Rhus hirta planting < grassy vegetation < Leymus sabulosus planting < grassy vegetation on humused technozem. On the dumps of mining quarries are Pinus pallasiana planting < grassy vegetation < Robinia pseudoacacia planting, that can be for highly creation on technozems.
