A list of 101 species of hoverflies recorded from three high altitudinal belts in the Eastern Sayan mountain region is given. Most species belong to the subfamilies Syrphinae (60 species) and Eristalinae (38 species), while Pipizinae and Microdontinae are presented by two and one species, respectively. Totally, 96 species were found in the forest zone, 37 species were found in the mountain tundra and only Platycheirus chilosia has been caught in the golsty belt. New synonymy is established: Melangyna arctica (Zetterstedt, 1838) = Melangyna soszynskii Mielczarek, 2013 syn. n., = Melangyna tsherepanovi (Violovitsh, 1965) syn. n.

Sayan Mountain

Shrub tundra is an integral component of the high mountains of the Altai-Sayan mountain region (ASMR). Phyto-mass reserves were identified in 42 shrub communities located in 24 mountain systems and 3 bioclimatic sectors of the ASMR. Accounting of AGP communities was carried out by the method of mowing in 10-fold repetition, UGP - by the monoliths method in 5-fold repetition on sites with an area 0.25 m2. In the studied tundra, the AGP reserves vary from 874 to 6815 g/m2 on the slopes and from 1419 to 2352 g/m2 on the tops of the ranges. A region of aboveground mass high index is traced on the Southern slopes in the humid and semiarid sectors (2768-6815 g/m2) and it becomes dis-placed to the Northern slopes in the arid sector (2338 g/m2). In the structure of the AGP, the live mass of communities on the slopes is at the level of 197-1727 g/m2, and in the aligned areas - 358-1037 g/m2. It has been established that on the Northern slopes the shrubs prevail in the live weight of the communities (421-899 g/m2, 53-77 %). During the transition to the Southern slopes in the botanical composition of the communities, the mass of shrubs remains high in the humid highland communities (660 g/m2), while in the semiarid and arid highlands they are replaced by lichens (367-461 g/m2) and sedges, respectively (33-53 g/m2). UGP of shrub tundra on different elements of the mesorelief is within the range of 2181-10 829 g/m2. On the slopes and aligned areas of mountain systems of ASMR various biocli-matic sectors, significant relationships were found between the aboveground and underground phytomass reserves (r = -0.93-0.97; n = 6).

The monograph presents an overview of the forest-steppe vegetation of the West Siberian Plain and the Altai-Sayan mountain region. The questions of bioclimatic zonation of the Altai-Sayan mountain region are discussed. The biodiversity of foreststeppe is characterized, the floristic classification is performed, the scheme of eco-phytocoenotic classification is given, the basic types of plant communities are described in comparative terms. The diversity of forest-steppe landscapes is revealed, the structure of their vegetation is analyzed. The phytogeographical division of forest-steppe is worked out.

The genus Daphnia O.F. Müller (Crustacea: Cladocera: Daphniidae) has a long history of its study, it attracts maximum attention of evolutionary biologists as compared to other cladoceran taxa. But still there are many unresolved problems concerning the genus taxonomy. We redescribe forgotten Daphnia (D.) turbinata Sars, 1903 which has a relatively narrow distribution in the Altay-Sayan mountain region (southern Siberia and Mongolia). Diagnostic characters of the taxon are discussed as well as possibilities of morphological discrimination of taxa within the D. (D.) longispina species group.
