metadata.name: dc.description.abstract
metadata.value: The article presents results of a study of the environmental conditions transformation during the formation
  of new phytocenoses by the grey alder. Processes of overgrowing meadows by alder entail a
  change of habitat characteristics, in particular, reduction of brightness and temperature, a signifi cant
  increase in litter thickness. In addition, abundance and biomass of earthworms per area unit is reduced
  in upper soil horizons under the alders, compared to the meadow. Conversion of environmental factors
  signifi cantly affects the development of herbaceous vegetation: species richness and abundance
  (cover) of herbaceous vegetation plummets under the influence of alder, as well as floristic heterogeneity
  of the cover.
  Undergrowth of spruce — indigenous tree species does not develop in the 60-year-old alder.
  Overgrowing meadows through the gray alder (compared with aspen and birch) inhibits the passage
  of autogenous succession, aimed at establishing indigenous vegetation type — spruce. Refs 29. Figs 5.
