The article provides data on the distribution of the invasive boxelder maple in the Altai Krai.  The article specifically considers its coenotic role in pine forests by the example of the Barnaul ribbon pine forest. A GIS project was developed to assess the distribution of boxelder maple in Altai krai. Mapping was based on the species location data obtained from the herbarium material (more than 500 sheets of the herbarium) deposited to the Altai State University (ALTB), the N.I. Vavilov All-Russian Plant Research Institute (WIR) and the V.L. Komarov Botanical Institute of the Russian Academy of Sciences (LE). To map the boxelder maple distribution, an analysis of the forest stand maps of the Barnaul ribbon pine forest was also carried out (2010, 2018). For each maple location, the stratum, the stratum area, and the stand formula are taken into account. Over the ten-year observation period, the area of maple and mixed forests with the participation of Acer negundo has increased almost 6 times here. Monodominant maple forests and mixed forests with the participation of boxelder maple as well as with other invasive species are formed. This leads to a considerable anthropogenic transformation of pine forests and a decrease in their environment-forming, social-economic and ecological significance. The study reveals that generative plants were not found in every coenopopulation. If the plants reached the reproductive stage, then, on the whole, males prevailed fivefold in the coenopopulation. Most of the studied coenopopulations consisted of pre-generative individuals, with the exception of occasional young generative ones. Most of the trees in the studied populations reached the age of 10–15 years. For forest communities of the Barnaul forestry, two age periods of the ontogenetic state have been established – pre-generative and generative, which indicates a relatively early age of the phytoinvasion and its active stage.

Droughts and insect outbreaks are primary disturbance processes linking climate change to tree mortality in western North America. Refugia from these disturbances—locations where impacts are less severe relative to the surrounding landscape—may be priorities for conservation, restoration, and monitoring. In this study, hypotheses concerning physical and biological processes supporting refugia were investigated by modelling the landscape controls on disturbance refugia that were identified using remotely sensed vegetation indicators. Refugia were identified at 30-m resolution using anomalies of Landsat-derived Normalized Difference Moisture Index in lodgepole and whitebark pine forests in southern Oregon, USA, in 2001 (a single-year drought with no insect outbreak) and 2009 (during a multi-year drought and severe outbreak of mountain pine beetle). Landscape controls on refugia (topographic, soil, and forest characteristics) were modeled using boosted regression trees. Landscape characteristics better explained and predicted refugia locations in 2009, when forest impacts were greater, than in 2001. Refugia in lodgepole and whitebark pine forests were generally associated with topographically shaded slopes, convergent environments such as valleys, areas of relatively low soil bulk density, and in thinner forest stands. In whitebark pine forest, refugia were associated with riparian areas along headwater streams. Spatial patterns in evapotranspiration, snowmelt dynamics, soil water storage, and drought-tolerance and insect-resistance abilities may help create refugia from drought and mountain pine beetle. Identification of the landscape characteristics supporting refugia can help forest managers target conservation resources in an era of climate-change exacerbation of droughts and insect outbreaks.

Abstract The Scots pine is one of the most important species in European and Asian forests. Due to a widespread occurrence of pine forests, their significance in the energy and mass exchange between the Earth surface and the atmosphere is also important, particularly in the context of climate change and greenhouse gases balance. The aim of this work is to present the relationship between the average annual net ecosystem productivity and growing season length, latitude and air temperature (tay) over Europe. Therefore, CO2 flux measurement data from eight European pine dominated forests were used. The observations suggest that there is a correlation between the intensity of CO2 uptake or emission by a forest stand and the above mentioned parameters. Based on the obtained results, all of the selected pine forest stands were CO2 sinks, except a site in northern Finland. The carbon dioxide uptake increased proportionally with the increase of growing season length (9.212 g C m-2 y-1 per day of growing season, R2 = 0.53, p = 0.0399). This dependency showed stronger correlation and higher statistical significance than both relationships between annual net ecosystem productivity and air temperature (R2 = 0.39, p = 0.096) and annual net ecosystem productivity and latitude (R2 = 0.47, p = 0.058). The CO2 emission surpassed assimilation in winter, early spring and late autumn. Moreover, the appearance of late, cold spring and early winter, reduced annual net ecosystem productivity. Therefore, the growing season length can be considered as one of the main factor affecting the annual carbon budget of pine forests.

The article is devoted to the study of the scientific and pedagogical activities of the famous Slavist A. N. Yasinsky in the last – Moscow-Minsk – period of his life based on the materials of the Belarusian archives. Revolutionary events of 1917–1921 forced him, like many other representatives of the capital’s intelligentsia, to look for work in new provincial universities. Since 1922 he has been teaching at the Belarusian State University, becoming one of the founders of Belarusian Medieval and Slavic studies. In 1928 he was elected an academician of the newly created Belarusian Academy of Sciences, where he continued his studies of both the Czech Middle Ages and the history of Belarus in the Middle Ages. However, external circumstances did not allow A. N. Yasinsky to create his own scientific school in Belarus, and his research of the 1920’s remained little known to specialists.

Anatoly Andreevich Gromyko, a professor of the Moscow State University, a corresponding member of the Russian Academy of Sciences reflects in his article on the destinies of mankind and the most complex problems facing the world community at the early 21 century under globalization and increased demand in global governance. In his analysis the author concedes that after numerous pieces of research on various aspects of these two phenomena, there are still more questions than answers. He believes that globalization might become a force serving not only private interests of big corporations but also the common good of humanity. Since interdependence is the main feature of our world we should not fall prey to the ideal images of global governance because there is no one size fit all global governance. The article elaborates the three most pressing world problems:– the need in a new way of thinking about globalization. According to the author the problems of globalization must be approached with knowledge of history and acknowledgement of social justice;– the need in morally acceptable balance among unifying potential of globalization, unchained global market and the state as the last resort of its nation;– the need to make United Nations a platform, where political and social democracy should lay ground for global governance so craved for by the mankind. The author pays special attention to the dichotomy between the force of law and the law of force as well as to the prospects for the new democratic global order accommodating the sustainable development of human civilization.
