The study is carried in the framework of the project “Urban planning retrospective of medium and small settlements of the Ob-Yenisei waterway”, which is aimed at studying the transformation of residential areas of one of the main waterways of Siberia, from Tyumen to Kyakhta. The coastal territory of the Tura, Tobol, Irtysh, Ob, Ket rivers of the Ob basin in West Siberia is studied. The theoretical study identifies and graphically displays medium and small settlements at different development stages of West Siberia. A retrospective of the settlements allows to determine their typhology in the waterway coastal zone in the 18–19th centuries. The quantitative data on each type of settlement are obtained, and the routes of communication are classified. In the 18th century, land directions rarely cross the settlements, most of them locate along the rivers, streams, elders and lakes. In the 19th century, local residential areas (houses, single yards, settlements, villages) along the land routes enlarge and form villages. A comparative analysis shows a high percentage of preserving the location, typhology and planning structure of the small settlements of the modern settlement system. In general, the period of urbanization is described from the late 18th and early 19th centuries.

Bee-farming is a promising branch of the agro-industrial complex in the Russian regions including the Altai Region with all required conditions for the development of the in-dustry. Numerous melliferous plants growing in the Altai Region is good bee forage which contributes to bee-farming development. Honeybees produce first-class hon-ey varieties with an extraordinary aroma and tastes from the nectar of the local melliferous plants. According to the plan of breed zoning, the European dark bee (Apis mellif-era melliferaL.) is recommended in the Altai Region. Intro-duced to West Siberia in the second half of the 18th centu-ry, these bees have adapted well to the local climate and settled in different natural zones. The comparison of the morphometric and economic indices of the Altai population with purebred individuals will make it possible to determine their position in the breed composition of honeybees. The data on the exterior characteristics of bees and the compo-sition of 2 honeybrands collected in the mountain-taiga zone of the Region is discussed. It was found that the bees of the Altai population, in terms of measured indices (the average proboscis length -6.2 mm; tergite 3 width -5.0 mm; cubital index -59.5%, negative discoidal dis-placement in 100% of individuals, etc.) were consistent with the standard of the European dark bee. Pollen study of 2 brands of centrifuged honey showed that the main pollen belonged to the plants of the Umbelliferae family (39.4%) in one sample and Compositae (56.5%) in another sample. The rest of the pollen was found in insignificant quantities and belonged to the plants of the following families: Rosaceae, Onagraceae, Labiatae, Fabaceae, Crucifers and Boraginaceae.

The aim of the study. The aim of the study was to estimate heterogeneity of moisture-related soil physical properties in a sequence of degraded hillslope soils in the cis-Salair region. The main tasks were to examine spatial fluctuations and changes in morphological and agrophysical properties of soils, differing in erosion degree, and assess their variability. Location and time of the study. The study was conducted in the forest-steppe zone in the Bugotak Hills (Novosibirsk region, Russia). A sequence of arable soils located along the 411 m convex hillslope with south-eastern exposition was investigated since July 01 till August 15, 2016. Main results. The article describes the variation of soil density, moisture content and temperature in a sequence of hillslope soils. The variation in the ploughed layer was found to be quite high, depending on the sampling scale. Examination of the spatial variability of the soil hydrophysical properties showed that the non-eroded podzolised chernozem (Luvic Greyzemic Chernozem) and toeslope meadow soil (Gleyic Greyzemic Phaeozem, Colluvic)had the highest density. The lower temperatures were recorded in the slightly eroded dark-gray forest soil (Luvic Greyzemic Phaeozem) and in the toeslope meadow soil, accumulating soil material eroded from the topslope. The temperature difference range between the “cold” and “warm” soils was 1.8 °С. Conclusions. Such studies have important prospects in development and introduction of agricultural technologies that are landscape-adapted, especially in areas with diverse relief and eroded soils. The main focus of such research should be the anti-erosion landscaping. The problem needs to be further studied within the framework of targeting the anti-erosion measures to geographic regions and natural zones.
