The first historical writings on Siberian urban residents in the second half of the XX century date back to 1960s. They were primarily dedicated to the working class. In 1990s, the writings were further broadened in the context of historical demography and urban development in historical perspective. The Institute of History of Siberian Branch of the Russian Academy of Science became the center to research Siberian towns and cities and their dwellers. S. Bukin, N. Guschin, V. Isaev and V. Isupov are among the most prominent scholars. In 2000s, the historians published a series of monographs, miscellanies and articles of conceptual significance. They introduced the concept of Siberian demographic transition and characterized it by the delayed and fragmentary nature of processes. East Siberian historical demography is less studied. L. Slavina pointed out delayed demographic transition. S. Rafikova argued for accelerated urbanization and young population in Siberian towns and cities. The researchers from the Republics of Khakassia and Tuva prepared a multitude of publications discussing the historical urban demography of the second half of the XX century. V. Kyshpanakova, N. Barantseva, Ye. Tinikova, Z. Anaiban, V. Boiko and Z. Dorzhu should be pointed out among them. The researchers suggested delayed demographic transition among the indigenous peoples of Siberia, urban residents including. They argued for Soviet industrialization of the region and its related urbanization. The analysis allows concluding that historical Siberian urban demography is expanding. Linking theory of modernization and concepts of urban and demographic transitions in historical analysis is an area of great promise and substantial potential. It allows gaining new knowledge about life and characteristics of Siberian urban population during the late Soviet period and noteworthy features of processes of urbanization. At the same time, other methodological approaches have not been implied. The works of foreign authors are poorly used. None of the above-mentioned researches has included either any comparative analysis, or mathematical modeling in their study. Such issues as epidemiological transition, migration, the way of life, departmentalism, mixed-nationality marriages, etc. require further research.

The article highlights the main stages and achievements of the 100-year historical path of the Institute for Mongolian, Buddhist and Tibetan Studies of the Siberian Branch of the Russian Academy of Sciences. The Institute traces its history back to the Buryat-Mongolian Academic Committee (Buruchkom) - the first research institution in the history of the Buryatia, which was founded on July 1, 1922. Today IMBT SB RAS is a unique academic institution in the East of Russia which carries out multidimensional research projects in the field of history and culture of the peoples of Central and East Asia. Specifically, it focuses on a comprehensive study of the problems of Mongolian, Buddhist and Tibetan studies, patterns of socio-economic, political, historical and cultural development of the Mongolianspeaking peoples of Russia and Central Asia. The results aimed at academic development of the Oriental space contribute to developing a positive dialogue between the West and the East, while the Institute itself looks ahead with confidence.

The monograph by E.S. Bushueva is devoted to the architecture peculiarities and origin of the Assumption Church of the Holy assumption Monastery, as well as the fate of people related to its activities. The monograph sources were documents deposited in the State Archives of the Trans-Baikal Region and National Archives of the Republic of Buryatia. The author’s attentive attitude to archival materials, their adequate interpretation made it possible to place the singular in the context of culture, to identify the general and the special. The research results indicate the fallacy of the view on the provincial abandonment of Siberian regions. In their historical period, many of them were outposts on the paths of development and advancement of Russia, modern ideas of architecture and art were embodied there, culturally significant buildings were created. The book, full of historical facts, evidence-based arguments, and the author’s reasoning, has become an important contribution to studying the religious life of Siberia.

The textbook under review is devoted to the history of the most difficult period of post-Soviet Russia - the 1990s. The review notes the relevance of the textbook prepared by the famous Russian historian Professor L.N. Slavina. It’s marked that the tutorial provides an analysis of transformations of all spheres of the socio-political and socio-cultural life of the Russian Federation. The textbook is in demand by historical faculties of Russian universities, as it gives basic answers to the most pressing questions of Russia’s recent history.

The capsule review of the scientific editor for the thematic issue of the Siberian Journal of Forest Science, 2022, number 3 is done, dedicated to silvicultural problems in Siberia.

As a result of an experiment on thinning of different intensity and the application of fertilizers (carbamide, 46 % as the active ingredient) in the young stands of the Krasnoyarsk forest-steppe, formed on former agricultural land, with the initial density 30 thousand trees per ha, data were obtained on the response of cenoses to the complex treatment. Dependences of growth on the age and initial density of plantings, and on the density and dose of fertilizer were built. It is shown that on the plots with the thinning intensity of 77 and 59 % of the number of trees, after 10 years it is necessary to carry out a second thinning treatment. It has been established that the growth response to the application of fertilizers begins from the fifth year after their application. The application of fertilizers makes it possible to reduce the competition between trees for environmental resources, which allows overdense young stands to provide the maximum possible productivity up to a certain age. The results obtained can be used not only in solving forestry problems of increasing the productivity of plantations, but also to increase their carbon sequestration functions.

Based on the analysis of the wood increment dynamics in the middle-aged pine forests of the Krasnoyarsk forest-steppe of various structure, formed through thinning of different intensities and the introduction of various doses of mineral fertilizers (carbamide, 46 % of the active substance), the regularities of changes in the current annual increment were established. A model allowing assessing the trends in increment with age and density of stands growing both without and with the use of fertilizers has been proposed. Data are presented indicating that in the conditions of the Krasnoyarsk forest-steppe, due to the application of fertilizers, the current annual increment in pine plantations can be increased by 1.2-6.8 m³/ha compared to the reference site. Differences in the response of stands to fertilization in the first five years and the next three years were revealed it has been found that the current annual increment increases significantly starting from the sixth year after fertilization. The density-age optima of the productivity of pine stands, providing a multiple increase in the increment of managed stands as compared to the reference site were established. The obtained knowledge is the theoretical basis for the implementation of a model of intensive use and reproduction of forests in the best forest growing conditions, and will also be useful in creating carbon farms, which main purpose is to reduce the carbon footprint of industrial enterprises.

The dynamics of forest inventory indicators, attrition and wood growth of 35-year-old pine Рinus sylvestris L. crops with various density are analyzed, Pine crops were created in 1982 by V. N. Sukachev Institute of Forest Russian Academy of Sciences, Siberian Branch under the leadership of A. I. Buzykin on former agricultural lands in Bolshemurtinsky district of Krasnoyarsk Krai. The initial density of the stands varied in a wide range from 0.5 to 128.0 thousand trees per ha. The assessment of the stand density influence on the growth and productivity of young pine stands at the age of 2, 5, 12, 15, 20, 25, 30 and 35 years old was carried out. It has been established that since the age of five, the process of intensive self-thinning of trees has been observed, at initial planting density 90.0 thousand trees/ha the density decreased to 10 thousand trees/ha by the age of 35 years. At the initial density less than 10 thousand trees/ha the self-thinning intensity is significantly lower and the stand density has decreased by less than 2 times over the same period. It is shown that at the initial stage of stand growth there is a growth increase with the initial planting density, reaching the plateau at a density of over 70.0 thousand trees/ha. With age reaching the plateau occurs with the lower initial density. At the age of 20, the maximum increase was at the initial density from 50.0 to 70.0 thousand trees/ha, by the age of 30 it shifted to a density range from 30.0 to 50.0 thousand trees/ha. The relationship between the current annual increment, age, and the initial and actual densities of pine crops has been established. In the age range studied there is a tendency of increasing the increment with age, although for the crops with the initial density higher than 90 thousand trees per ha in the range of 15 to 22 years the decrease of annual increment is observed, which is evidently connected to the escalating of concurrent relations in cenosis. Thus, it can be suggested that high rates of carbon deposition at the initial stage of high-density stands creation can be maintained under the condition of periodic thinning, regulating the stand density.

A simulation model of the growth of pine stands is proposed. The model, taking into account the competition for the available resource, allows to calculate the increase in trunk diameter for each tree in the simulated area, as well as to derive the taxation characteristics: stand density, completeness, stock of stem wood and make monitoring the dynamics of all these indicators in increments of one year. The model takes into account the relative location of trees in the tree stand, their size and the amount of available resource for each tree. The verification of the model was carried out using the materials of long-term research on permanent research plots of young, middle-aged and ripe stands. Several scenarios for the growing of pine stands are considered. The influence of cutting on the dynamics of a number of taxation characteristics is studied. These are the average diameter the average diameter of the trunk and the increase in diameter, the value of the average annual increase; the density of the stand; the stock of stem wood. The proposed simulation model is an effective tool for studying the growing of stands and serves as an alternative to time-consuming field studies, which are difficult to implement over long time intervals. Modeling allows studying the impact of logging in forests for various destinations. It is possible to choose such a system of forest care activities using the analysis of the dynamics of the main taxation indicators, which provides the most complete implementation of the tasks of intensive reforestation by varying the intensity and frequency of cutting during modeling.

The basis for forecasting the growth of forest stands is the site index scales. Expansion of knowledge about the processes of functioning of forest ecosystems, the nature of changes in the process of growth of morphological indicators of trees and stands, their interconnections and interdependencies, and the creation of a more suitable mathematical apparatus and appropriate software for describing biological processes form the prerequisites for formulating and solving the problem of forecasting the growth of stands on higher methodological level. The aim of this work is to assess the predictive ability of the growth equations obtained using the generalized algebraic difference approach (GADA) to describe the course of growth of tree stands at the average height and to construct a site index scale. The data for the study were general tables of the course of growth of complete (normal) pine stands North Eurasian. A total of 25 equations obtained using the GADA approach are analyzed. Comparative analysis showed that the best quality of data alignment is provided by an equation based on the Mitscherlich function (also known as Drakin-Vuevsky, Chapman-Richards) with the replacement of parameters responsible for the limiting values of the height and the shape of the curve. This model is polymorphic, has the shape of a sigmoid curve and variable asymptotes, i.e. takes into account most of the properties imposed on the growth rate models in height. Model errors are distributed depending on the selected forecasting interval and the site index of the stand. With an increase in the forecasting period, an increase in the error occurs. For all intervals of the forecast range, the value of the mean absolute error is not exceeding 2.01 %. The highest average absolute forecast error (1.1-2.2 %) is characteristic of the extreme site index classes (I^b, V, V^a and V^b). The methodology considered in the study can be applied to develop models of the growth rate of stand inventory variables of other forest-forming species in Russia.
