The data on distribution of small spruce bark beetle Ips amitinus (Eichh.) (Coleoptera: Curculionidae: Scolytinae), a new invasive pest of European origin on the territory of Western Siberia are presented. Alien bark beetle species was recorded in the Siberian pine forests of the Tomsk, Kemerovo and Novosibirsk regions. According to the modern data the total invasion range is more than 30 thousand km² with a tendency to further expansion. The number outbreaks of I. amitinus in Siberian pine forests near settlements, in nature preservations and plantations of Pinus sibirica Du Tour cause significant harm to pine-nut harvesting and selective breeding.

Abstract The total of 257 trees from the ten natural Siberian stone pine populations of West Siberian Plain, Ural Mountains and Kuznetsk Alatau were studied with the eight nuclear microsatellite loci. Differentiation of population groups indicates the possible existence of separate refugia in the past in the Urals and Kuznetsk Alatau. The northern populations of Western Siberia were characterized by a reduced level of genetic diversity, which could be a consequence of the founder effect in the process of P. sibirica migration from the southern regions of Western Siberia and the Urals since the end of the last glacial maximum. The genetic variability distribution among populations shows the uneven dynamics of Siberian stone pine migration from the zones of supposed refugia. The map of the proposed ways of Siberian stone pine migration from the zones of possible refugia was constructed, and it is in a good agreement with the results of palynological investigations.

In the Ob river floodplain between the mouths of its tributaries Vakh and Tym (within the limits of Aleksandrovskiy district of Tomsk region), phytocoenoses belonging to 9 associations and 2 communities of Braun-Blanquet classification vegetation classes are listed. Class Lemnetea is represented by associations Ricciocarpetum natantis (Segal 1963) Tx. 1974, Lemnetum trisulcae Soó 1927, Stratiotetum aloidis Miljan 1933; class Potametea is done by asso­ciations Potametum perfoliati Koch 1926, Myriophylletum sibirici Taran 1998, Myriophylletum verticillati Soó 1927, Potametum graminei Koch 1926, Potametum pectinati Carstensen 1955, Nymphoidetum peltatae (All. 1922) Bellot 1951, as well as Sagittaria natans and Potamogeton natans—Ceratophyllum demersum communities. The syntaxa distribution in Western Siberia and adjoining territories is characterized.

The study of secondary changes of acidic effusives with reservoir properties from the top of the Western Siberia pre-Jurassic complex (Tomsk Region) was produced. Lithological, petrographic and mineralogical features of these rocks indicate their change by low-temperature hydrothermal solutions, while weathering products, which are widely spread at the top of the basement, have not been clearly defined. Reservoir properties of studied rocks were formed probably due to fracturing and leaching.

Показаны особенности формирования кроны кедра сибирского (Pinus sibirica Du Tour) после декапитации, произрастающего на плантации «Метеостанция» в Учебно-опытном лесхозе Караульного лесничества в условиях юга Средней Сибири. Объектом исследований являлась 54-летняя плантация кедра сибирского, выращенная  из семян, заготовленных в 1964 г. в Лениногорском лесхозе (Республика Казахстан). Декапитация проведена у деревьев 42-летнего возраста в 2005 г. с оставлением ствола высотой 1,4-1,7 м. Верхняя часть кроны удалена на 50,0-66,7%. В 2017 г. деревья достигли высоты 5,6-9,1 м. Количество лидирующих побегов, заменивших центральный, составило 3-7 шт., длина которых за 12-летний период достигла 4,0-7,6 м. Деревья с диаметром ствола 12-18 см имели по 3-4, с диаметром 20-26 см – по 6-7 шт. лидирующих побега. Установлено, что уровень изменчивости высоты деревьев низкий; прироста побегов, диаметра ствола – средний, количества лидирующих побегов – высокий. Наибольшей высотой (9,1 м) отличалось дерево № 4-98, превосходя другие особи на 8,3-62,5%. Сопоставлено количество боковых ветвей, образовавшихся на лидирующих побегах за 5 лет (2013-2017 гг.). Отмечено, что их средний прирост за исследуемый период находился в пределах 23,6-45,5 см. Между диаметром ствола и числом лидирующих побегов коэффициент корреляции (r) равен 0,619; числом лидирующих побегов и количеством сформированных боковых ветвей спустя 7-12 лет после декапитации – 0,770, диаметром ствола при обрезке и высотой деревьев после 12 лет декапитации – 0,738.

The possibilities of Geothermy as a geophysical method are studied to solve forecast and prospecting problems of Petroleum Geology of the Arctic regions and the Paleozoic of Western Siberia. Deep heat flow of Yamal fields, whose oil and gas potential is associated with the Jurassic-Cretaceous formations, and the fields of Tomsk Region, whose geological section contents deposits in the Paleozoic, is studied. The method of paleotemperature modeling was used to calculate the heat flow density from the base of a sedimentary section (by solving the inverse problem of Geothermy). The schematization and mapping of the heat flow were performed, taking into account experimental determinations of the parameter. Besides, the correlation of heat flow features with the localization of deposits was revealed. The conceptual and factual basis of research includes the tectonosedimentary history of sedimentary cover, the Mesozoic-Cenozoic climatic temperature course and the history of cryogenic processes, as well as lithologic and stratigraphic description of the section, results of well testing, thermometry and vitrinite reflectivity data of 20 deep wells of Yamal and 37 wells of Ostanino group of fields of Tomsk region. It was stated that 80 % of known Yamal deposits correlate with anomalous features of the heat flow. Bovanenkovskoe and Arkticheskoe fields are located in positive anomaly zones. 75 % of fields of Ostanino group relate to anomalous features of the heat flow. It is shown that the fields, which are characterized by existence of commercial deposits in the Paleozoic, are associated with the bright gradient zone of the heat flow. The forecast of commercial inflows in the Paleozoic for Pindzhinskoe, Mirnoe and Rybalnoe fields is given. The correlation between the intensity of naftidogenesis and the lateral inhomogeneity of the deep heat flow is characterized as a probable fundamental pattern for Western Siberia.
