ADAPTATION PROCESSES IN BIOCOENOSES OF CONTAMINATED PLOTS OF THE SEMIPALATINSK TEST SITE

Abstract

The article presents results of adaptation processes of main types of ecosystems (steppe, meadow, halophytic) and various types of disturbed ecosystems territories of the Semipalatinsk test site (STS). It was found that radiation pollution provokes change of morphological and anatomical structure of plants and leads to formation of some adaptation signs. Formation of adaptation signs of perennials and shrubs is expressed more clearly. Change of morphological and anatomical structure of plants happens more often in meadow (mesophyte) communities and at disturbed areas.
