| 1 | The peculiarities of reproduction of mountain plants connected with extreme conditions of inhabitants are considered. It is stated that high-mountain plants present a considerable variety of systems, and that corresponds to the variety of inhabitants in the mountain landscape. | 1217 | ||||
| 2 | The article gives the critical analysis of biomorphoiogical terminology that is used in modern botany. Different approaches to the plant life form as a key term in biomorphology that are taken in different Russian and Western European research schools are discussed. On the base of the icritical analysis, expediency of physiognomic approach to the definition of plant life form is shown. | 1465 | ||||
| 3 | Photosynthesising surface extension tendency is characteristic for the most of plants that determinates high rate of growth and space expansion. Such plants can be called «occupants», and their life forms considered as «open». At extreme environment conditions (deserts, high-mountains, polar biomes), not space occupation but homeostasis maintenance by the surface area restriction due to spherical, compact life forms development, became the priority strategy (cushion plants, cactuses, etc.). These plants are «limiters», and their life forms are «closed» | 1448 | ||||
| 4 | The dependence of various high-mountain vegetation types on the climate features and the climatic tolerance of the plant communities are revealed on the base of long-term field research in Altay mountains. Keywords: climate, high-mountain, ecological factors, vegetation types, habitats | 1460 | ||||
| 5 | On the analogy of ideal continent concepts, spatial distribution of high-mountainous landscapes of temperate and subtropical zones of Eurasia depending on altitude and climate aridity is analyzed. Keywords: high-mountain, landscape, vegetation | 1375 | ||||
| 6 | Biomorphological spectra in pseudo tundra phytocoenoses are analysed at the article. It is shown that the ecotopic differentiation of phytocoenoses in extreme conditions is reflected in the composition of life forms, which have a significant functional loading in extreme conditions. Keywords: vegetation, life forms, synmorfology, pseudotundra, high mountains | 1442 | ||||
| 7 | The relative biomorphological diversity reflects the proportion of life forms and species in phytocenoses. In extreme conditions a decrease in species diversity of plants in phytocenoses can be partly compensated by their biomorphological varienty, which has a positive effect on their stability. Keywords: biodiversity, phytocenoses, species, life forms, biomorphs | 1412 | ||||
| 8 | The connection of epimorphological structure with ecological strategies and reproduction features of plants in extreme high-mountain conditions is considered in the article. There is shown, that the approaching to the ecotopic limit furthers the growth of life forms diversity and plants sizes. Keywords: high-mountain (alpine) plants, life form, ecotop, thermal regime of plant, ecological niche, ecological strategies, spatial strategies, reproduction strategies | 1442 | ||||
| 9 | The distribution, climatological and ecological analyses revealed that tundra plant communities dominated by Dryas have relatively small range of ecological tolerance. The structure of tundra is defined by biomorphological features of dominant species, Dryas oxyodonta Juz., and specific character of their relations to other components of the community. Keywords: Dryas-dominated tundra, high-mountain phytocoenoses, synmorphology, biomorphological specters of plants | 1410 | ||||
