Аннотация: The developmental history of peatland and dry land vegetation within the Ob-Vasugan watershed of Western Siberia was characterized according to features of the plant communities and climatic changes which were revealed by stratigraphic, spore-pollen and C-14 (carbon) data obtained from a vertical peat profile 'Vodorasdel'. Changes in the paleoecological environment over the last 10000 years were divided into five periods. The climate was characterized in the Holocene according to these periods. At the watershed studied, peatland-forming processes started about 9510 years ago resulting in 550 cm of peat accumulation. The rate of peat accumulation within the watershed decreased over time from 1.9-0.3 mm year(-1).

Аннотация: A reconstruction of forest-cover dynamics in the northern part of the Kas River basin has been done for the first time. This study based on a palynological analysis of the peat profile. Six pollen zones and respective phases of forest evolution are distinguished. It is inferred that changes in the forest species composition over the last 8000 years were determined by variations in the global and regional climate. The warm and humid climate of the Atlantic period promoted the development of dark coniferous birch-spruce-fir forests. Cooling and smaller precipitation in the Subboreal period led to a change in dominant species to Scotch pine and birch-Siberian pine forests with an admixture of spruce and fir. In the Subatlantic period, closed coniferous forests eventually evolved, with Siberian pine-pine remaining dominant.

Аннотация: Environmental conditions causing stress have a significant effect on the generative organs of Scotch pine. The parameters characterizing pine pollen are subject to significant interannual variations and are closely connected with weather and climatic conditions in the period of pollen formation. Airborne pollutants affect the quality of pine pollen, which is especially apparent in the years favorable for the formation of microspores. The ability of Scotch pine pollen to germinate and form pollen tubes in the regions with different technogenic loads proved to be significantly lower than in tree stands of the background areas.

Аннотация: Structure of crown and viability of generative organs of Siberian fir were studied in disturbed forest ecosystems near Baikal Lake. The crown structure changes in damaged trees: a zone of subapical drying appears and apical dominance is lost. Needle chlorosis and necrosis appear and proceed in sprouts of male sexualization. The tree top including the female generative organs does not show degradation symptoms during about 30 years and produces seed cones. Processes of degradation in male generative zone greatly influence on fir tree pollen. Pollen viability of fir trees varied from year to year in different trees but always pollen quality of trees growing in the Khamar-Daban Mts in the air pollution zone was more poor in comparison with the pollen of trees at die Baikal Lake shore. Tree pollen growing in the Khamar-Daban Mts germinates in vitro but pollen tubes are formed short and not viable. Seed quality of fir trees is very low, A lot of seeds are sterile. Empty seeds prevail. The formation of empty seeds was caused by the low pollen germination in ovules and as a whole absence of pollen in ovules. The high sterility of generative organs and especially of Abies sibirica pollen can limit gametic selection and decrease fir diversity in forest ecosystems near Baikal Lake.

Аннотация: A bioclimatic vegetation model is used to reconstruct the palaeoclimate of Siberia during the mid-Holocene, a warm. moist period also known as the Holocene climatic optimum. Our goal is to determine the magnitude of climatic anomalies associated with mapped changes in vegetation classes. Reconstructed anomalies are the logical outcome of the bioclimatic assumptions in the Siberia vegetation model operating on location-specific differences in the palaeomap of Khotinsky and the modern map of Isachenko. The Siberian vegetation model specifics the relationship between vegetation classes and climate using climatic indices (growing-degree days, dryness index, continentality index). These indices are then converted into parameters commonly used in climatic reconstructions: January and July mean temperatures. and annual precipitation. Climatic anomalies since the mid-Holocene are then displayed by latitude and longitude. An advantage of a model-based approach to climatic reconstruction is that grid cells can be modelled independently. without the need for interpolation to create smoothed temperature and precipitation contours. The resulting pattern of anomalies is complex. On average. Siberian winters in the mid-Holocene were 3.7 degrees C warmer than now, with greater warming in higher latitudes. The major winter warming was concentrated in the Taiga zone on the plains and tablelands of East Siberia, where a warm and moist climate was necessary to support a broad expanse of shade-tolerant dark-needled Taiga. January temperatures averaged about 1 degrees C warmer than now across southern Siberia. although large areas show no change. July temperature anomalies (0-5 degrees C) are distributed mostly latitudinally, with anomalies increasing with latitude above 65 degrees N. At latitudes below 65 degrees N, July temperature was nearly the same as today across Siberia. Based on July temperatures. Siberian summers in the mid-Holocene were 0.7 degrees C warmer than today's. Annual precipitation in Siberia was predicted to be 95 mm greater in the mid-Holocene than now. Most of the increase was concentrated in East Siberia (154 mm average increase). The precipitation anomalies are small in the south. Large precipitation anomalies are found in central and northeastern Siberia. This location corresponds rather closely to the large anomalies in January temperature in East Siberia. The annual precipitation Increase was > 200 mm more than present precipitation in Yakutia. This increase corresponds to the deep penetration of moisture-demanding dark-needled species (Pinus sibirica. Abies sibirica, Picea obovata) into East Siberia in the mid-Holocene, where currently only drought-resistant light-needled species (Larix spp.) are found. Another area of increased precipitation was along the Polar Circle in West Siberia and at the base of the Taymyr Peninsula in East Siberia. In combination with 2-5 degrees C warmer summers, moister climates there allowed forests to advance far northward into what is now the Tundra zone.

Аннотация: Two quantitative methods were used to reconstruct paleoenvironments and vegetation in the Altai-Sayan mountains, Central Asia, during the Holocene. The 'biomization' method of Prentice et al (1996 Clim. Dyn. 12 185-96), applied to the surface pollen record, worked fairly well in the reconstructions of current vegetation. Applying this method to fossil pollen data, we reconstructed site paleovegetation. Our montane bioclimatic model, MontBioCliM, was used inversely to convert site paleovegetation into site paleoclimates. The differences between site paleo and current climates served as past climate change scenarios. The climatic anomalies for 2020, 2050, and 2080 derived from HadCM3 A1FI and B1 of the Hadley Centre, UK, served as climate change scenarios in the 21st century. MontBioCliM was applied directly to all climate scenarios through the Holocene to map past and future mountain vegetation over the Altai-Sayan mountains. Our results suggest that the early Holocene ca 10 000 BP was cold and dry; the period between 8000 and 5300 BP was warm and moist; and the time slice ca 3200 BP was cooler and drier than the present. Using kappa statistics, we showed that the vegetation at 8000 BP and 5300 BP was similar, as was the vegetation at 10 000 BP and 3200 BP, while future vegetation was predicted to be dissimilar to any of the paleovegetation reconstructions. The mid-Holocene is frequently hypothesized to be an analog of future climate warming; however, being known as warm and moist in Siberia, the mid-Holocene climate would likely impact terrestrial ecosystems differently from the projected warm and dry mid-century climate.

Аннотация: The prolongation of the warm season during autumn, which has become typical for Siberia in the past 5-6 years, has caused changes in the terms of reproductive processes in microsporangia of Scotch pine in the Krasnoyarsk region. Meiosis has started to begin in the autumn of the year preceding pollination, and then come to an end the next spring, whereas usually this process has occurred in the spring of the year of pollination. Under such conditions the division of microsporocytes is accompanied by different abnormalities, causing various anomalies and the incomplete development of pollen grains.

Present-day and mid-Holocene biomes reconstructed from pollen and plant macrofossil data from the former Soviet Union and Mongolia

Аннотация: Fossil pollen data supplemented by tree macrofossil records were used to reconstruct the vegetation of the Former Soviet Union and Mongolia at 6000 years. Pollen spectra were assigned to biomes using the plant-functional-type method developed by Prentice ct al. (1996). Surface pollen data and a modern vegetation map provided a test of the method. This is the first time such a broad-scale vegetation reconstruction for the greater part of northern Eurasia has been attempted with objective techniques. The new results confirm previous regional palaeoenvironmental studies of the mid-Holocene while providing a comprehensive synopsis and firmer conclusions. West of the Ural Mountains temperate deciduous forest extended both northward and southward from its modern range. The northern limits of cool mixed and cool conifer forests were also further north than present. Taiga was reduced in European Russia, but was extended into Yakutia where now there is cold deciduous forest. The northern limit of taiga was extended (as shown by increased Picea pollen percentages, and by tree macrofossil records north of the present-day forest limit) but tundra was still present in north-eastern Siberia. The boundary between forest and steppe in the continental interior did not shift substantially, and dry conditions similar to present existed in western Mongolia and north of the Aral Sea.

Аннотация: Fossil pollen data supplemented by tree macrofossil records were used to reconstruct the vegetation of the Former Soviet Union and Mongolia at 6000 years. Pollen spectra were assigned to biomes using the plant-functional-type method developed by Prentice ct al. (1996). Surface pollen data and a modern vegetation map provided a test of the method. This is the first time such a broad-scale vegetation reconstruction for the greater part of northern Eurasia has been attempted with objective techniques. The new results confirm previous regional palaeoenvironmental studies of the mid-Holocene while providing a comprehensive synopsis and firmer conclusions. West of the Ural Mountains temperate deciduous forest extended both northward and southward from its modern range. The northern limits of cool mixed and cool conifer forests were also further north than present. Taiga was reduced in European Russia, but was extended into Yakutia where now there is cold deciduous forest. The northern limit of taiga was extended (as shown by increased Picea pollen percentages, and by tree macrofossil records north of the present-day forest limit) but tundra was still present in north-eastern Siberia. The boundary between forest and steppe in the continental interior did not shift substantially, and dry conditions similar to present existed in western Mongolia and north of the Aral Sea.

Аннотация: To answer the question "Has the recent warming no analogues in the Siberian north?" we analyzed larch tree samples (. Larix gmelinii Rupr.) from permafrost zone in the eastern Taimyr (TAY) (72В°N, 102В°E) using tree-ring and stable isotope analyses for the Climatic Optimum Period (COP) 4111-3806 BC and Medieval Warm Period (MWP) 917-1150 AD, in comparison to the recent period (RP) 1791-2008 AD.We developed a description of the climatic and environmental changes in the eastern Taimyr using tree-ring width and stable isotope (?13C, ?18O) data based on statistical verification of the relationships to climatic parameters (temperature and precipitation).Additionally, we compared our new tree-ring and stable isotope data sets with earlier published July temperature and precipitation reconstructions inferred from pollen data of the Lama Lake, Taimyr Peninsula, ?18O ice core data from Akademii Nauk ice cap on Severnaya Zemlya (SZ) and ?18O ice core data from Greenland (GISP2), as well as tree-ring width and stable carbon and oxygen isotope data from northeastern Yakutia (YAK).We found that the COP in TAY was warmer and drier compared to the MWP but rather similar to the RP. Our results indicate that the MWP in TAY started earlier and was wetter than in YAK. July precipitation reconstructions obtained from pollen data of the Lama Lake, oxygen isotope data from SZ and our carbon isotopes in tree cellulose agree well and indicate wetter climate conditions during the MWP.Consistent large-scale patterns were reflected in significant links between oxygen isotope data in tree cellulose from TAY and YAK, and oxygen isotope data from SZ and GISP2 during the MWP and the RP.Finally, we showed that the recent warming is not unprecedented in the Siberian north. Similar climate conditions were recorded by tree-rings, stable isotopes, pollen, and ice core data 6000 years ago. В© 2013 Elsevier Ltd.

Specific features of meiosis in the Siberian Fir (Abies sibirica) in the forest Arboretum of the V. N. Sukachev Institute, Russia

Аннотация: Investigating the tolerance of plant reproductive systems to environmental changes has become a research priority under current climate change scenarios. Successful plant conservation requires knowledge of plant reproductive biology, particularly the meiotic characteristics of planted species. Meiosis, as part of microsporogenesis, is a critical plant developmental stage controlling future pollen quality. Meiosis in a Siberian fir (Abies sibirica) plantation, established in the Forest Arboretum of the Sukachev Institute, Russia, was studied from 2002 to 2004. The microsporogenesis pattern found for the Siberian fir appeared to be largely similar to that exhibited by other conifer species. Meiosis in the Siberian fir has the following characteristics: asynchrony, rapid progression of telophases I and II, and parallel and linear spindle arrangements at different meiosis II stages. General and specific meiosis irregularities were recorded at each stage. Some specific features of meiosis and the specific development of some irregularities were revealed. Pollen development analysis showed that irregular pollen grains made up less than 1% of all grains. The specific features of meiosis identified in fir trees growing in the Arboretum indicated low resistance of male reproductive structures to climatic changes and might account for high fir pollen sterility in this new environment.

Аннотация: Studies of microsporogenesis in the Siberian larch growing in Krasnoyarsk and its suburbs have shown that meiosis starts in October. Microsporocytes winter at prophase I (leptoneme, diploneme). Reduction divisions in male generative buds are resumed and terminated in spring, in March. However, in the case of thaws during the autumn-winter period, meiotic division proceeds in the larch buds and this leads to the formation of degrading tetrads and pollen. Hence, the organic quiescence is absent in the larch in winter. It was shown that in the larch growing in the city, meiosis proceed more asynchronously than in the background tree stands. An increase of chromosomal aberrations during the reduction division was noted under the conditions of technogenic pollution.

. - ISSN 1067-4136
Аннотация: A peat profile, 5.5 m in depth, laid in a bog complex comprising frost mounds, bog hollows, and lakes was studied. This bog complex was located in one of the most swamped regions of the middle taiga of the West Siberian Plain. Botanical and spore-pollen analyses of the peat field were conducted. Across the thickness of the peat deposit, 17 points at 25-cm intervals were dated by the radiocarbon method. The dynamics of vegetation and climate during the past 9500 years were determined. It was revealed that, during this period, the rate of peat accumulation constantly tended to decrease, with some fluctuations. The results of mathematical and ecological simulation of this process predict that it will cease in another 1000 years. В© 1997 MAHK Hayka/Interperiodica Publishing.

Seed productivity of macrostrobili and the quality of seeds in Abies sibirica in disturbed forest ecosystems of the mountains of Southern Siberia

Аннотация: Seed productivity of the macrostrobile and seed quality in drying and healthy stands of the Abies slbirica growing in the mountains of the Southern Siberia - Khamar-Daban and Western and Eastern Sayany - were studied. It was established that under any growing conditions of fir, the seed productivity of its macrostrobile is very high, but the quality of the seeds produced is very low. In high mountains, where an intensive drying of fir forests takes place, seed sterilization increases. Most of the sterile seeds are hollow, which is connected with the low pollen quality. It is concluded that in Abies sibirica growing in the mountains of Southern Siberia, the reproductive potential of the species drops. It is assumed that formation of sterile seeds in a fir may cause the lack of forest-forming processes in fir forests. В© 1996 MAHK Hayka/Interperiodica Publishing.

Аннотация: The sulfur content in needles, the morphological structure of the crown, and the pollen quality of drying and healthy Siberian fir trees growing at different distances from the Baikal Integrated Pulp-and-Paper Mill were investigated. The highest content of sulfur in the needles was revealed in trees growing on the Khamar-Daban chain at height of 1100-1200 m a.s.1. It was determined that intensive fir forest decline, changes in the morphological structure of the crown, and the production of low quality pollen take place under the same conditions.

Аннотация: Prehistoric and early historic human cultures are known to be closely connected to and dependent on their natural environments. We test the hypothesis that climate change influenced the means of subsistence of ancient tribes and favored agricultural or cattle herding economic strategies. Our study area is the Khakass-Minusinsk Hollow, located in the foothills of the Sayan Mountains, south-central Siberia, which was, for a few millennia, a buffer zone for human migrations across the Great Eurasian Steppe. Three different methods (the Montane BioClimatic Model, MontBCliM; the biomization method; and the actualizm method) are employed to reconstruct vegetation taken from the fossil pollen of sediment cores in two mountain lakes at eleven time slices related to successive human cultures back to the mid-Holocene. MontBCliM model is used inversely to convert site paleo-vegetation into site paleo-climates. Climate-based regression models are developed and applied to reconstructed climates to evaluate possible pasture and grain crops for these time slices. Pollen-based reconstructions of the climate fluctuations uncovered several dry periods with steppe and forest-steppe and wetter periods with forests since 6000 BP. Grasslands increased by an order of magnitude during the dry periods and provided extensive open space suitable for pastoralism; however, both grain and pasture yields decreased during these dry periods. During wetter climates, both grain and pasture yields increased twofold and supported more fixed human settlements centered around farming and cattle herding. Thus, the dry periods favored pastoralist rather than farming activities. Conversely, tribes that practiced agriculture had some advantage in the wet periods. © 2014 IOP Publishing Ltd.

Аннотация: Prehistoric and early historic human cultures are known to be closely connected to and dependent on their natural environments.

Жизнеспособность пыльцы некоторых видов Picea (Pinacrae) в условиях Красноярска

Аннотация: Исследована пыльца пяти видов рода Picea: P. mariana (Mill.) Britton, Sterns et Poggenb., P. pungens Engelm., P. glehnii (F. Schmidt) Mast., P. abies. (L.) H. Karst, P. obovata Ledeb. f. seminskiensis Lucznik, а также дерева P. obovata Ledeb., в кариотипе которого выявлены добавочные B-хромосомы. При интродукции в условиях резко континентального климата Сибири (дендрарий Института леса СО РАН, г. Красноярск) размеры пыльцевых зерен варьируют в различные годы исследований в пределах 28.7 % (тело п. з.), 33.2 % (воздушные мешки), количество аномальных пыльцевых зерен не превышает 27.8 %. Жизнеспособность пыльцы в целом удовлетворительная, варьирует у разных видов в зависимости от погодно-климатических условий года развития и в значительной степени коррелирует с содержанием в ней крахмала и жиров. Максимальным количеством аберраций пыльцы и минимальной жизнеспособностью характеризовалась P. obovata с тремя добавочными В-хромосомами. Характер сезонно-ритмических изменений развития и жизнеспособность пыльцы свидетельствуют об успешной адаптации видов рода Picea к резко континентальному климату Сибири. Высокий адаптивный потенциал демонстрируют P. mariana и P. pungens.

Аннотация: Cytoembryological research of the ovules in experiments with interspecific hybridization of Pinus sibirica (pollination be the pollen of P. koraiensis, P. armandii, P. parviflora, P. strobus, P. hokkaidensis, P. wallichiana, P. monticola, and P. Nembra) revealed that the development of megagametophytes occurred in them by the usual scenario and resulted in the formation of mature archegonia. Pollen successfully germinated on the nucellus of ovules. However, disturbances were observed in the process of male gametophyte development, and pollen tubes on the nucellus were not visible by the period of archegonia maturation. Fertilization was usually absent. The development of embryonic channel is determined by egg cell maturity. The only exception was the variant of the controlled pollination of Pinus sibirica x P. Nembra, in which the embryo has been formed.
