. This commentary is devoted to the article by V. G. Gorshkov and A. M. Makaryeva (2020), in which the division of biota in forest ecosystems is considered using the concepts of both "immotile life" and "locomotive life". The article presents well-known arguments to prove the erroneousness of using such concepts, because motion is a fundamental property of living creatures and is realised at all levels of living system organisation. Representatives of all the kingdoms are widely distributed in space at different stages of the life cycle. In opposite the view by Gorshkov and Makarieva (2020), which the large herbivorous are destroyers of terrestrial ecosystems emphasizes, in the current commentary is considered the importance of mammals in forests, for the circulation of matter and ener-gy flow in forest ecosystems to maintain biodiversity and the efficiency of trophic systems.
． 这篇评论专门针对V. G. Gorshkov和A. M. Makaryeva(2020)的文章，其中使用“不动生物”和“运动生物”的概念来考虑森林生态系统中生物群的划分。这篇文章提出了一些众所周知的论点来证明使用这些概念是错误的，因为运动是生物的基本属性，并且在生命系统组织的各个层面都能实现。所有王国的代表在生命周期的不同阶段广泛分布在空间中。Gorshkov和Makarieva(2020)认为大型草食性动物是陆地生态系统的破坏者，与此相反，在当前的评论中，哺乳动物在森林中的重要性被认为是森林生态系统中物质和能量流动的循环，以维持生物多样性和营养系统的效率。

. For two decades after an occasional introduction in the middle of the 20th century, marsh frogs (complex Pelophylax ridibundus ) have spread across many water bodies of Central Kazakhstan (Kazakh Upland, KU). The questions of which genetic forms of the complex have become entrenched in the region and how successful the progress of their present settlement has been were priorities for our study. The survey of the region was carried out in May-August 2021, covering the seasons of mating and early growth. Molecular genetic analysis was performed for the mitochondrial ND2 gene. In contrast to what had been expected, our study showed a reduction in the area inhabited by marsh frogs in KU, and a noticeable decrease in their abundance. The frogs disappeared from many points in the Nura and Ishim rivers, and significantly decreased in number on the western and northern coasts of Lake Balkhash. However, it remained a common species in the floodplain of the Irtysh Rivers and on its tributaries . For the first time for the KU the genetic affiliation of the populations (by mitochondrial ND2 gene) was determined and the habitation of two genetic forms – the invasive Anatolian P. cf. bedriagae and the native "Bal-khash" form. The habitat of P . cf. bedriagae was established as being on the northern coast of Lake Balkhash. The native "Balkhash" form was identified on the western coast of Lake Balkhash and in the River Shar (Irtysh River Basin). In the rest of the KU, the distribution of the two forms was variegated, and in a number of water bodies they lived together. To the north of KU lives Anatolian P. cf. bedriagae (in Kostanay and Pavlodar provinces); and to the south the "Balkhash" form (in the Balkhash-Ili Depression, Almaty City and Lake Issyk-Kul). The relation-ship between a change in climatic cycles and the success of the past dispersal of amphibians and the present reduction in their populations in the region has been marked. The disappearance of the frogs on Lake Balkhash is most likely due to the dispersal of the snakehead ( Channa argus ). Molecular genetic analysis data indicated a wider distribution and wider adaptive potential of P. cf. bedriagae than previously thought. The study identified a number of promising tasks for future.

We studied the development of 13 tree species growing in the undergrowth of hornbeam forests in the Kanev Reserve in Cherkasy Oblast (Ukraine) and spruce-broadleaved and pine forests in the Bryansk Forest Reserve (Russia). We analysed the following biological features of these species in limited light conditions: age, average annual increase in biomass (production), growth patterns of the aboveground axis, crown area, specific density of the leaf area and the ability to change to a quasi-senile state. Analysis of these biological properties allowed us to distinguish two large groups of species, which are characterized by a set of interrelated features. The first group included Betula pendula, Pinus sylvestris, Populus tremula, Quercus robur and Salix caprea. For these species, low shade tolerance is combined with rapid development, high intensity in growth and physiological processes (photosynthesis and respiration), with large average annual biomass increase and short lifespan when growing in the undergrowth due to a lack of light. This set of features allows the trees to occupy habitats with good light conditions, which are found in large-sized treefall gaps as well as sparse forests. The second group included Acer campestre, A. platanoides, A. tataricum, Carpinus betulus, Fraxinus excelsior, Picea abies, Tilia cordata and Ulmus glabra. For these species, high shade tolerance is combined with slow growth rates, with a low intensity of growth and physiological processes, with small average annual biomass increase and long-term existence of individuals in limited light conditions. Species with this complex of features are adapted to habitats beneath a dark forest canopy formed by spruce and broadleaved trees with crowns that cast deep shadow. These large species groups appear in the vegetation cover as complementary formations and form contrasting communities. Tree species within each group determine the resilience of forest communities as they are able to replace each other in the event of a reduction in the number of individuals of any species. The basis of this ability is the congeniality of species according to their light requirements and biological properties.

Relevance and objectives. Natural disturbances of the forest stand are the events that cause changes in the structure of the forest stand, the availability of resources and environmental conditions. These are key processes of the forest dynamics which ensure successful recruitment and coexistence of different species. The objective of this study was to reconstruct the disturbance history in the late-successional Korean pine-broadleaved forest of southern Sikhote-Alin. The study findings will help us to understand how forest ecosystems emerge and function without human influence and to take measures necessary to restore the forests that are already disturbed. Materials and methods. The disturbance history was reconstructed using the dendroecological approach. We analyzed 961 samples of 5 dominant species, i.e. Abies nephrolepis (Trautv.) Maxim., Betula costata Trautv., Picea jezoensis (Lindl. еt Gord.) Fisch. еx Carr., Pinus koraiensis (Siebold et Zucc.) – Korean pine, and Tilia amurensis Rupr. We identified growth releases using the boundary-line release criteria. Results. For the first time it was possible to reconstruct the history of natural forest stand disturbances on the area of 5 ha for 255 years. In most of the time, periods of sharp increase in radial growth occur in no more than 5–10 % of trees. At the same time, 4 periods of major natural disturbances were revealed, i.e. 1765–1774, 1845–1849, 1880–1889, and 1960–1964. The largest one occurred in 1960–1964, when more than 20 % of trees showed growth release. Conclusions. From 1750 to 2005, there were no catastrophic natural disturbances in the study area, but relative severe disturbances were detected with groups of trees having fallen out, as well as minor disturbances (loss of single trees). The loss of individual trees with subsequent formation of small gaps in the canopy contributes to continuous and stable existence of the stand. Most likely the gaps are formed due to strong winds. This provides stable generations flow of trees of different species.

РАЗНООБРАЗИЕ РАСТИТЕЛЬНОСТИ НА ЭЛЕМЕНТАХ ВЕТРОВАЛЬНО - ПОЧВЕННЫХ КОМПЛЕКСОВ Abstract. We analyzed the diversity of vascular plant species growing on microsites formed after tree falls with uprooting as a result of catastrophic windthrow that occurred in the temperate broadleaved forests of the Kaluzhskie Zaseki Reserve in 2006. Size characteristics of pits and mounds formed by uprooting of 110 individuals of 9 tree species were measured. Vegetation on microsites formed by 45 fallen trees of 8 species was described. We distinguished the following microsites: 1) top of the mound; 2) back side of the mound; 3) front side of the mound (from the trunk side); 4) pit over the mound; 5) pit in front of the mound in the case of rotational treefalls; 6) part of the trunk close to the roots (deadwood). Vegetation on 45 plots of 1x1 m in size and located close to but not affected by tree uprooting (reference plots, or reference communities) was also described. The results of the indirect ordination analysis revealed that the ecological and phytocoenotic microsites; 6 species were not found before the windthrow study in the descriptions of broadleaved and aspen forests of the Reserve, and 8 species were found in the descriptions of those forests no more than three times. New species are mostly species from the boreal ( Phegopteris connectilis, Sambucus racemosa ), nitrophilous ( Rubus caesius ), water-marsh ( Epilobium hirsutum , Epilobium palustre ), meadow-edge ( Bromopsis inermis , Hypericum hirsutum , Conyza canadensis , Vicia cracca ), and piny ( Calamagrostis epigeios ) ecological-coenotic groups. In general, the increase in plant diversity in the area of catastrophic windthrow is caused by the massive emergence of new microsites (pits, mounds and deadwood) and the subsequent appearance of species with different ecological and coenotic traits.
