Some aspects of the use of diatoms in diagnostic of environment

In the article the question of the possibility of using a unique group of diatoms in the diagnosis of environmental conditions.DiscussedcontroversialviewsontheconceptsofBacillariophytaasphytoliths.Forexample,literature data and own research presents diagnostic possibilities of diatoms: Marking soil formation processes, particularly the process of development of primary substrates, the geographical distribution of diatoms in soils. In particular, the features of the taxonomic composition of diatoms in bogs ecosystems, steppe, taiga and some others. The possibility of using diatoms as biological indicators of current conditions and the reconstruction of paleoecological environment. Includingspecial attention given to the possibilities of diagnostic spaleoecological conditions through modern representatives Bacillariophyta. However, there is still a lot of questions. It is important to accumulate data on the ecological spectrum of species of diatoms, especially environmental preferendum each of them to reliably diagnose the conditions of modern systems and reconstruct paleosoils conditions. What kind of phytocenotic indicators should be used to characterize the type (incidence, activity, ecol-cenotic significance) using the known formulas in the soil algology. To what extent correct this extrapolation? For now are dominated questions, but the prospects of this direction of research question remains.
