During the geobotanical survey of the vegetation of the southern part of the Nature Park "Numto", located within the subzone of the northern taiga in the center of the West Siberian Plain, 140 species of bryophytes, including 87 species of mosses and 53 species of liverworts, of which 24 species of mosses and all liverworts are new to the territory of the Nature Park. Two species of sphagnum mosses – Sphagnum inexpectatum and S. mirum – are the most important finds for the Western Siberia. Sphagnum inexpectatum is listed for the first time for the territory of Khanty-Mansi Autonomous District. The information on ecology and phytocenotic confinement of 18 species of mosses, known earlier in the Nature Park from one point or on a few and single finds, is supplemented. An annotated list of all identified species of bryophytes is given.

New locations of 25 rare species of mosses, known earlier in the Khanty-Mansi Autonomous District from one or a few locations, are provided. Their ecology, phytocenotic affinity and peculiarities of the distribution on the territory of the autonomous district and taiga zone of the Western Siberia as a whole are discussed. A high proportion of rare species in the moss flora of the central part of the taiga zone of Western Siberia resulted from limited distribution or absence of suitable habitats associated with stony substrates and outcrops of groundwater rich in mineral nutrition elements, as well as from intermediate (ecotone) position of the flora on the latitudinal bioclimatic gradient from south to north.

The ancient fortified settlement of Amnya I is a unique Early Neolithic site in the northern taiga zone of Western Siberia (Khanty-Mansi Autonomous Okrug, the Amnya river). It is located on a promontory and has three lines of defense and ten dwelling depressions. The structures of the excavated dwellings are very similar, though the artifact assemblage appears rather heterogeneous. We carried out a technical and technological analysis of ceramics, which showed no correlation between the texture, on the one hand, and the morphology and ornamentation of pots on the other one. Planiographic analysis of ceramics showed that vessels with comb and incising patterns are found in different dwellings, although there are objects in which both groups lie together. Various categories of stone implements (bladelets and polished arrowheads) also appear on different parts of the settlement. Most likely, the observed differences in the artefact complexes of objects are associated with the stages of the functioning of the settlement. The absolute chronology does not yet clarify the sequence of erection and existence of objects. New AMS date is probably vulnerable to a significant reservoir effect. The abundance of unsolved issues of absolute and relative chronology makes the resumption of research on this unique site urgent.

Приведены данные исследований естественного лесовозобновления гари в условиях Западно-Сибирского среднетаежного равнинного лесного района таежной лесорастительной зоны (на примере Урайского лесничества, расположенного в юго-западной части Ханты-Мансийского автоном- ного округа – Югры на территории кондинского административного района). Оценка лесовозобновле- ния проведена по методу учетных лент, заложенных на расстоянии 50 и 100 м от стены леса. Данные исследований показали непрерывность лесовосстановительного процесса на гари. Отмечается наличие всходов, самосева и подроста высотных категорий «мелкий», «средний» и «крупный». лесовозобновле- ние гари происходит двумя древесными породами – сосной и березой. По существующим нормативам возобновление сосны оценивается как хорошее. По количеству всходов и подроста преобладает сосна. При удалении от стены леса на 100 м происходит уменьшение количества всходов и подроста всех кате- горий крупности в 2–3 раза в сравнении с аналогичными показателями на расстоянии 50 м от стены леса независимо от вида древесной породы. Во всех высотных категориях отмечается преобладание жизне- способного подроста сосны – до 90–100 %, что является основным показателем успешности лесовос- становления исследуемой гари на данном этапе развития. береза в большинстве случаев представлена сомнительными по жизнеспособности экземплярами. В качестве лесохозяйственных мероприятий мож- но предложить проведение мониторинга за состоянием подроста и уходные мероприятия за подростом. The results of features formations of post-fire pine undergrowth on burnt area of the middle taiga zone of Western Siberia (for example, Uraisk forestry department) in location of the Khanty-Mansi Autonomous Area. Undergrowth was studied on tapes laid out parallel to the forest edges at a distance of 50 and 100. According to studies it is observed of reafforestation continuity of burned areas. The presence of sprouting and undergrowth of the high- elevation categories «small», «medium» and «large» is noted. The burned areas reforestation with two tree species – pine and birch proceed. According to current specification, the pine natural regeneration is assessed as «normal». The amount of pine undergrowth is greater than the amount of birch undergrowth. To be at 100 m from forest edges the number of seedlings and undergrowth decreases by 2–3 times in comparison with the same indicators at 50 m from the forest edges. There is a predominance of vital pine undergrowth – up to 90–100 %. This is evidence of the successful reforestation of burned areas at this stage of development.

The antioxidant activity of lipids extracted from peats and sapropels from Tomsk and Novosibirsk Regions and Khanty-Mansi Autonomous Okrug is estimated by microcalorimetry. The presence of antioxidants (AO) in the lipids of all peats under study and in a sapropel from the Dolgoye Lake is confirmed by the presence of an induction period (950–14000 s) on the heat release curve and the decrease in the final rate of the model reaction of the initiated cumene oxidation by 25–90%. The total amount of lipid antioxidants varying within the range (22–183)∙10-3 mol/kg is determined by the degree of inhibition of the oxidation reaction. The concentration of identified organic compounds (25–186 μg/g) including alkanes, fatty acids, steroids, terpenoids, and tocopherols is determined by chromatography-mass spectrometry, which correlates with the amount of AO in the peat. It is shown that the samples of initial peats are ordered by their antioxidant activity as follows: sphagnum fuscum > cotton grass > lowland wood > sphagnum phallax. Sphagnum fuscum peats are characterized by the maximum biological activity, which makes it possible to recommend them as an optimal raw material for practical use.

The north of Western Siberia has seen intensive economic development. Exploration and mining for mineral resources, active road and pipeline construction, urban development, and agriculture favor invasion and dispersal of alien plant species across the Subarctic region. The paper reports new records for eight alien species and hybrids previously unknown from northwest Siberia and the flora of northern Asia: Alopecurus geniculatus L., Anthyllis vulneraria L. subsp. vulneraria, Aquilegia atrata W.D.J. Koch, A. vulgaris L., Epilobium franciscanum Barbey, Galium album Mill. subsp. album, Petunia atkinsiana (Sweet) D. Don ex W.H. Baxter, Primula elatior (L.) Hill. These species were spotted in 2012–2014 in the towns of Salekhard, Nadym, Novy Urengoy, Tarko-Sale, Gubkinsky, and Noyabrsk in the Yamal-Nenets Autonomous District, Western Siberia (Russia). Species, synonyms, overall distribution, habitat preferences, and species taxonomy with remarks on identification and differentiation from the most similar taxa occurring in the study area, as well as the list of localities are presented.
