ABOUT THE PHYTOCENOTIC ROLE OF THE DARKNOUS SPECIES IN THE SOUTHERN URALS ^{[№ 12 ' 2017]}
In the Southern Urals, dark coniferous species of trees — Siberian spruce (Picea obovata Ledeb.) and Siberian fir (Abies sibirica Ledeb.) grow on medium-altitude mountains (the region of mountain taiga dark coniferous forests) and on low mountains in the western part (broad-leaved and dark coniferous forests) where they dominate in natural dark coniferous biocenoses. Regional ecological and biological characteristics of dark coniferous tree species and their phytocenotic characteristics are relatively poorly studied, stationary studies were conducted only on local sites. Very relevant is the study of the relationship of these species in biocenoses and the identification of their role in ecosystems. The research was carried out on the territory of the South Ural State Nature Reserve, which is located within two botanical and geographical areas — in the region of mountainous taiga dark coniferous forests and in the broadleaf and dark coniferous forests. Both areas were covered by in-patient and route-based research. As a result of stationary studies, indicators of phytocenotic activity of dark coniferous tree species (density of stand, timber stock, density of undergrowth), as well as their ecotopic areals have been determined. The results of the investigations make it possible to evaluate phytocenotic positions and phytocenotic activity of dark coniferous tree species in the Southern Urals. Studies have shown that in dark taiga forests dark coniferous trees actively participate in the process of forest formation, they form natural biocenoses in most ecotopes of the forest belt, as well as in a number of ecotopes above the forest belt. In broadleaf-dark coniferous forests, the participation of dark coniferous tree species in the process of forest formation is limited to only a part of ecotopic space, in a limited number of ecotopes Siberian spruce and Siberian fir dominate in natural forest communities.

QUERCUS ROBUR L. IN THE SOUTH URAL RESERVE ^{[№ 10 ' 2015]}
On the basis of the results of research and fixed-route summarizes the distribution of Quercus robur in the South Ural Reserve. The participation of Quercus robur in the formation of various types of natural and secondary forests. A general assessment of the role of Quercus robur in shaping forest communities. The reserve Quercus robur common in the western part, in the area of broad-leaved coniferous forests. In the area of research areas met estesvenno deciduous forests dominated by Quercus robur. It is an old forest with large old trees Quercus robur, Aser platanoides, and Tilia cordata. In all societies marked by a low number of undergrowth Quercus robur, with a higher number of other broad-leaved species. These communities occupy local areas. Ecotopia characterized by the most favorable thermal regime and maximum rates of heat supply. Natural communities are also communities with domination Aser platanoides. Lots of communities larger area. In these communities Quercus robur takes 10-20% of the weight of the tree layer, occurs sporadically in the composition of the undergrowth. In the semi-deciduous communities with domination of Tilia cordata as a part of the tree layer and undergrowth sporadically present Quercus robur, often it is not. The reserve Quercus robur is also found in semi-deciduous conifer communities, as well as derivatives of secondary communities with domination and Betula pendula and Populus tremula.
