Abstract	The problem of quantifying earthworms is that the size of most part of the soil population is calculated per unit volume and the number of earthworms per unit area. This makes incomparable the results both of quantitative indicators of earthworm population in different soils and the number of worms and other soil invertebrates. This article presents a new approach to the faunistic and quantitative account of earthworms in forest communities. The significance of dead wood in the study of earthworm population is shown in the article. The article also presents the technique of quantitative evaluation of Lumbricidae that live in the soil and in the dead wood per unit volume – 1 m3. Examples of the number of earthworms per unit volume – 1 dm3, provided the actual habitat of earthworms is only in the upper 10-cm layer of soil or per unit volume 100 dm3 – in the case of a low number of earthworms, are considered in the article. In the dark coniferous forests of the Pechora-Ilych and Teberdinsky reserves the most favorable habitats of Lumbricidae were identified, communities with their highest species richness and abundance were identified.

Abstract	A fir-spruce-linden herbs forest and fir-spruce tall herbs forest on brown mountain soil in the Visimsky State Natural Biosphere Reserve were studied. In each type of forest, the biodiversity and variability of the chemical composition of ground cover and litter plants in different seasons were studied, and the relationship between the chemical composition of plants and the chemical composition of soils was assessed. Found that in spring the content of Fe, Cr, Rb, Ti, Zn, Ni, Al, S and P in the ground cover is higher, and by the end of the growing season the content of Mn, Sr, Ca, K, Mg and Cl increases. Ground cover plants of the studied forests contribute to the accumulation of Fe, Al, Mg, Ba, Ti, Mn, Ni, Cr and Zn in the soil due to their concentration in roots. In the chemical composition of the litter of the fir-spruce-linden herbs forest, the content of Ca, S, Sr, Ba, Mg, Fe, Ba, and Ti is higher than that of the fir-spruce tall herbs forest, which is reflected in the increase in the content of these elements in the organic horizon of the studied soils.

Abstract	The reconstruction of the verbal pre-anthropogenic Northern Eurasia forest cover has been proposed on the basis of paleontology and historical ecology data analysis. It was used as a basis for evaluating the ability of the reserves in the studied area to act as reference objects capable of performing the ecosystem living soil cover functions. The analysis indicated immense anthropogenic transformation of the Biota in this territory and the requirement for urgent measures to restore the full-fledged Biota of the reserves at the state and global levels. A list of necessary activities for the initial phase of Biota recovery in the modern protected areas has been proposed.

Abstract	Most woodlands of the Northern Eurasia are represented by bilberry-green moss spruce-fir forests. At the same time, a tall herb type of spruce-fir forests that occupies a much smaller area was identified and described. The objective of this work is to evaluate and compare the species richness and productivity of the ground vegetation of tall herb spruce-fir (unique) and bilberry-green moss spruce-fir (typical) forests of the Northern Urals. Based on previous studies, two forest types were selected in the foothill part of the Pechora-Ilych nature reserve with tall herb and bilberry-green moss ground vegetation, where total mapping, determination of microsite area and geobotanical descriptions had been carried out previously. Material for determination of the aboveground and below-ground phytomass and chemical composition of plant species was collected in 2017–2018. The concentrations of C and N in plant samples were measured on the elemental analyzer, and Mg, Al, P, S, Cl, K, Ca, Fe, and Zn content was found using the method of measuring mass fraction of the element in powder samples by X-ray fluorescence analysis. It was found out that the total phytomass of vascular plants in the ground vegetation of tall herb forests is 5 times higher than that of bilberry-green moss forests. The phytomass of mosses, on the contrary, is 4.4 times lower in tall herb forests in comparison with bilberry-green moss forests. Examination of ecological-coenotic groups of plants in terms of the content of chemical elements taking phytomass in consideration shows that the greatest contribution to the accumulation of macro- and microelements in the tall herb spruce-fir forest is made by the plants from tall herbs, boreal dwarf shrubs and boreal small herbs groups; in the bilberry-green moss spruce-fir forest, the main role is played by mosses and boreal dwarf shrubs. To assess the content of biogenic elements in the ground vegetation a differentiated approach was suggested, which included accounting for above-ground and below-ground ...

Abstract	Background. The systematic position of the earthworm Dendrodrilus rubidus (Bimastos rubidus) has been changed many times due to differences in its anatomy and external morphology, which were revealed in individuals that at first glance belonged to the same species. Deviations from existing diagnoses also made taxonomic determination difficult. The research goal is to conduct comparative morphometric and molecular genetic analyses of D. rubidus (B. rubidus) individuals from different regions of Russia and Belarus to identify accurate diagnostic features. Materials and methods. For the study, we collected four samples of adult individuals of D. rubidus (B. rubidus), depending on geographical location. The worms were collected in the territories of Russia (European part, Western Siberia, North-Western Caucasus) and Belarus. Morphometric analysis was carried out according to the main qualitative and quantitative anatomical and morphological features. The variability of the mitochondrial cytochrome oxidase I (cox 1) gene used in molecular taxonomy was evaluated using molecular-genetic analysis. Further the data obtained from the two analyses were compared. Results and conclusions. Previously, it was believed that only two subspecies of D. rubidus (tenuis and subrubicundus) were present in the studied territories, which are currently considered to be species forms. During the study, we found three forms of this species: tenuis, rubidus and subrubicundus. The revealed anatomical and morphological differences make it possible to determine the species forms of adult individuals of D. rubidus, taking into account possible deviations from generally accepted diagnoses. There were no significant molecular-genetic differences between the different species forms.

Abstract	From the prospective of ecosystem ecology, the huge role of the concept "complementarity" in perceiving the mechanisms of sustainable existence of the natural (pre-anthropogenic) biota is substantiated. A comparison of structural and functional organization between the paleobiota of Northern Eurasia and its fragments, survived until the present day, the modern biota, was performed in the main types of conservation areas. The incompleteness of the modern biota in natural reservations and its main cause are shown: direct or indirect destruction of key species that determined the possibility of the existence of large groups of subordinate species is described. It has been found out that as the anthropogenic exploration of Northern Eurasia intensifies, the ability of the biota’s fragments ("debris") to support ecosystem functions of the biosphere decreases. It is concluded that a fundamentally new direction in the protection of nature is to be developed: "Pleistocene Rewilding" formed on a world-wide basis as a result of the awareness of the need for active restoration of the biosphere functions of the Earth's ground cover.

Abstract	One of the essential tasks of sustainable forest management is to maintain native biodiversity. Primary forest research is one of the ways to understand what this biodiversity is. Matherials and methods. The primary, as confirmed by their land-use history and structural peculiarities, mesic dark-conifer forests remain in Visim and Pechora–Ilych nature biosphere reserves (boreal and sub-boreal zones respectively, the Ural Mountains, Russian Federation). We compared the primary forests and post fire 100-year small-leaved deciduous forests by diversity of vascular flora and soil invertebrate macrofauna. Results and discussion. The diversity of some functional groups of species (low boreal herbs, earthworms) in post fire forests is lower than in primary forests, the research shows. These species largely depend on deadwood and other tree-related microhabitats common in the primary forests but not so in the 100-year post fire forests. Repeated fires at intervals of several decades, as is the case with the use of prescribed fires in forest management, will be expected to reduce the biodiversity quality of these specialist species. Additionally, we revealed that post fire forest flora is more synanthropic in the woodland of a small area (Visim reserve) than in the intact forest landscape (Pechora–Ilych reserve). It demonstrates that, within extensive woodlands, native forests are more resilient to sporadic stand-replacing disturbances than small woodlands. Conclusion. Strict conservation of intact forest landscapes is necessary as they serve as large buffer areas around the remaining primary forests to maintain native biodiversity.

Abstract	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 energy flow in forest ecosystems to maintain biodiversity and the efficiency of trophic systems.
