Based on the analysis of ecotope schemes, the article attempts to delineate the ecotopic ranges of broad-leaved species on the eastern border of their geographical distribution within the subzone of broad-leaved dark coniferous forests. The term "ecotopic range of a species" is used, which means a set of ecotopes or types of habitats occupied by cenopopulations of a species. The article analyzes 3 ecotope schemes of the Ufa Plateau, on the basis of which the ecotopic areas of broad-leaved species are outlined. The author's scheme of ecotopes of the area of broad-leaved dark coniferous forests of the Southern Urals is presented and the ecotopic ranges of broad-leaved species in this area are outlined.

Within the Western slope of the Southern Urals, there are plenty of basite dyke complexes of Riphean to Vendian among Precambrian terrigenous-carbonate formations. In metamorphic formations of the Taratash complex (Archean to Early Proterozoic, the northern closure of the Bashkirian meganticlinorium) there was observed the andesitic dyke with isotopic age of 71±1 Ma (U-Pb SHRIMP II on zircons) and near Bakal two bodies of gabbroids with zircons of similar ages were found. These are the first evidence of possible Mezozoic magmatism in this region.

Successional Stages

The secondary birch and aspen forests of middle stages of succession of the central elevated part of the Southern Urals are studied. 4 subassociations, 1 community, and 7 variants in the alliances of Aconito-Piceion and Piceion excelsae are allocated. It is shown that the floristic composition of aspen and birch secondary forests in the age of 60—80 years is almost identical to the natural forests. However, a slight increase the coenotical role of light-requiring species of grasslands and hemiboreal forests in the secondary communities of the class Brachypodio-Betuletea was noticed as well as some reduction of role the shade-tolerant species of nemoral complex and species of boreal forests of the class Vaccinio-Piceetea. Dominant tree layer under the canopy of secondary series is marked by an active growth of natural tree species.

Xerophillous pine-larch forests of the Southern Ural have been described as a new alliance Caragano fruti­cis—Pinion sylvestris. They occur on steep slopes of upper parts of mountain ridges with poorely developed stony soils. Alliance asigned to the class Brachypodio pinnati—Betuletea pendulae, order Chamaecytiso ruthe­nici—Pinetalia sylvestris. Associations Carici caryophyl­leae—Pinetum sylvestris and Ceraso fruticis—Pinetum sylvestris with four subassociations are described. Eco­logical and floristical peculiarities of new alliance in comparison with another alliances of the order Cha­maecytiso-Pinetalia and with siberian class Rhytidio rugosi—Laricetea sibiricae have been discussed.
