Analysis of the ratio of species and varieties biomorphological some high-phytocenoses Gorny Altai

The variety of life forms in the phytocenosis is an important aspect of biodiversity. The link between the diversity of life forms and species diversity in plant communities is reflected in the relative Biomorphological Diversity, the analysis of which the example of alpine vegetation of the Altai Republic is devoted to this article. With the help of the original forms of life have been conducted comparative studies of model-fi totsenozov relating to different types of alpine vegetation. For the sample used in the most typical plant communities and plant communities, which are at the limit of ecological tolerance for this type of vegetation. The results showed that the majority of high-phytocenoses characterized by species and balance biomorphological compositions. We can assume that this feature is an adaptive trait. For phytocenoses growing in the most severe environmental conditions, there was a trend compensate low species diversity diverse life forms. Meadow plant communities have relatively low rates of biomorphological diversity. In the series "tall subalpine meadows - srednetravnye alpine meadows - low grass alpine meadows" Biomorphological diversity tends to increase, while the increase in species diversity is hampered because of the increasing severity of the overall environment. Tall subalpine meadows the most humid areas of the Altai are characterized by a high degree of variation of species diversity indices in the space at stable and low diversity of life forms. Tundra plant communities developing in more severe conditions, have a relatively high species diversity and Biomorphological that is associated with a variety of types of adaptation strategies with a significant reduction of the role of the dominant. Some phytocenoses trend towards a relative increase biomorphological diversity is not associated with a variety of biomes, and a decrease in species diversity in the ecological limits of growth dryas tundra and subalpine meadows of tall transition to the stage of menopause. Variation of relative biomorphological diversity within one type of vegetation could indicate a large extent its environmental tolerance.
