This study addresses Russian iron artifacts from the Narym Selkup cemetery Migalka, dating to the late 1600s to early 1700s. Two most important categories of tools are described—knives and axes. In terms of morphology, knives fall into two groups: straight-backed and those with convex (“humped”) backs. The combination of a “humpbacked” blade, typical of native manufacture, and Russian hilt plates precludes an unambiguous ethnic attribution. Special attention is paid to knives with fi ligree-enamel hilt plates as markers of high socio-economic status. The garniture evidences northern Russian origin. The metallographic analysis of knives (22% of the sample) revealed two technological groups: made of solid steel and welded. Axes, made by Russian artisans, are of the shaft-hole type and fall into four types. The analysis, relating to 42% of the sample, indicates two techniques: welding of a steel blade onto an iron base or a piece of raw steel, and using irregularly carbonized metal for forging the entire axe. Ferrous metal items follow the Russian technological traditions. Three key factors accounted for the spread of Russian artifacts among the natives: “Tsar’s gift” for paying the yasak (tribute); colonization of Siberia followed by the emergence of trade manufacture; and the involvement of natives, specifi cally the Narym Selkups, in the all-Russian market. Our fi ndings attest to the relevance of iron artifacts from archaeological sites to the historical and cultural studies of the colonization period in western Siberia.

The analysis of geological and geophysical materials in order to study the peculiarities of the geological structure of the Vikulov Formation within the Vodorazdel license area was carried out. The presented factual material makes it possible to characterize the geological structure of the investigated area more informatively and for interpreting of seismic materials. The analysis of geological information (GIS and test results) confirms the approved water–oil contact (WOC) level in the investigated section of the deposit, which makes it possible to recalculate its reserves.

On the basis of author's graphical analysis method, the typification of lake ecosystems transformation scenarios depending on the size of lakes was carried out. It was confirmed that the type of transformation depends not only on size of the lake, but also on the landscape and climatic region in which it is located. The distinctive features of lake ecosystems transformation types in the European part of Russia and in Western Siberia were analyzed and compared.

Zoya Ilyinichna Glezer is the largest Russian micropaleontologist, a specialist in siliceous microfossils — Cenozoic diatoms and silicoflagellates. Since the 1960s, she systematically studied Paleogene siliceous microfossils from various regions of the country and therefore was an indispensable participant in the development of unified stratigraphic schemes for Paleogene siliceous plankton of various regions of the USSR. She made a great contribution to the creation of the newest Paleogene schemes in the south of European Russia and Western Siberia, to the correlations of the Paleogene deposits of the Kara Sea.

The directions and results of many years of research on the development and prevalence of diseases on perennial leguminous grasses (meadow clover, pannonian clover, sainfoin, sowing alfalfa) in Western Siberia are presented. A whole range of diseases was revealed, the intensity of development, which depends on weather conditions, resistance of varieties, plant age, etc.
