“…Russia's soil taxonomy [21] has various subtypes of humus horizons designated as such for their dependence on the soil organic matter content and pH range. These subtypes are the following: dark humus AU horizon with a neutral or alkaline pH and a humus content of more than 4-5%; gray humus AY horizon with a low humus content and an acidic pH range and light humus AJ horizon with a low humus content and alkaline pH values [16]. All of these types can be revealed in different natural zones; however, for the south taiga, only AU and AY are possible in its soil profiles.…”

“…The new Russian soil taxonomy [21,22] divided this type on the basis of various trenches of soils-primary soils (lithozems) and postlithogenic soils (organo-accumulative clay-illuviated carbonate soils). Thus, a previously single type of soil formation became divided by the new Russian classification [16]. Also, agrocarbonate soils were separated on the Rendzina soils were named and classified in various soil taxonomy systems.…”

Rendzinas in the taiga zone are intrazonal soils; moreover, all of their processes occur in ways that are different from podzolic soil formation, which is typical for the zonal taiga boreal ecosystem. At the same time, the habitats of carbonate soils are known as places in which there is a concentration of biodiversity in the more southern regions, as they are drier, are insolated, and have a higher trophic state than zonal podzols. The biotopes on carbonate soils are becoming more southern and are dominated by nemoralis species of flora, including abundant calciphilous plant species. Carbonate soils regulate biogeochemical processes within their distribution and in the geochemically subordinate landscapes of Northwest Russia. They are associated with the existence of a number of specially protected natural areas, as well as the implementation of a number of important ecosystem services. Carbonate soils of the southern taiga are endangered and require special protection. The belt of the carbonate soils in the northwestern Russian and Baltic regions extends to Poland and is the basis for the formation of a special landscape–ecological framework with specific biodiverse, biogeochemical, and geographical characteristics. The intensive extraction of limestone from quarries leads to the destruction of rendzinas, which makes them increasingly rare and extremely vulnerable. The rate of recovery of rendzina soils after technogenic impacts is much slower than the regeneration of zonal podzols; therefore, they are an almost non-renewable resource. Thus, rendzinas are an important component of the Northwest Russian soil cover, where all factors of soil formation “refract” and acquire specificity, leading to radical changes not only in the soil-forming potential of the environment but in all of the components of terrestrial ecosystems. In other words, the island of alkaline rocks inherited from the ancient seas is currently pedogeochemically actualized in the soil cover of vast taiga areas.

“…These soils are especially characterized by their soil-forming material containing calcium; this material is formed on limestones, dolomites, and milestones. In the southern part of European Russia in forest zones of the Northern Caucasus Mountains, Rendzik Leptosol soils with different genesis are widespread on a significant area -more than 1.2 million hectares (Konyushkov et al, 2019). The granulometric composition of these soils is mainly loamy and heavy-loamy clay-silt fraction.…”

<p class="71">Clear-fell harvesting significantly alters ecosystem attributes at multiple spatial scales. The results of a study of the dynamics of changes in Rendzik Leptosol and Greyic Phaeozem Vertic forests in the middle mountains of the North-Western Caucasus after clear-cutting in 2010-2020 are presented. Immediately after clearing the forest, areas with varying degrees of disturbance of the soil and vegetation cover were identified in the clearings, from maximum disturbance in the central part of the clearing to slight disturbance on their periphery at different elevations of 540-1600 meters above sea level (masl). The soil covering is represented with Rendzik Leptosol and Greyic Phaeozem Vertic. Among used metrics were temperature, humidity, texture density, penetration resistance, structural and aggregate composition, and other soil parameters. On felling areas, increased temperatures and decreased soil humidity were recorded. The temperature of Rendzik Leptosol at a depth of 10-30 cm changes within the range of 1-15°С in the period 2018-2020. The terrain elevation affects the soil due to the temperature gradient significantly. Rendzik Leptosol is much colder at an elevation 1640 meters above sea level than at 1200 meters above sea level. The temperature of Phaeozem (540 meters above sea level) reaches 20°С during the summer months at a depth of 10 cm. Soils in felling have differences in structural and aggregate composition and water resistance of aggregates. The study results can be used in assessing damage to ecosystems after deforestation and developing methods for accelerating the restoration of soil properties after deforestation. The result of the study can be applied to assess the change in the state of ecosystems after forest degradation. The most informative diagnostic indicators for assessing the state of ecosystems after forest degradation are discussed in the article.</p>

“…Soils formed on the products of weathering of dense carbonate rocks are among the least studied in the northeast of the European part of Russia. Comparative analysis of literature data covering various natural zones reflects significant differences of the taiga soils of continental regions on carbonate rocks and their analogues in the humid (subgumidic) areas of moderate continental climate [18][19][20][21][22][23][24].…”

Karst Ecosystems of Middle Timan, Russia: Soils, Plant Communities, and Soil Oribatid Mites

Oribatid mites are distinguished by high taxonomic diversity and abundance in almost all natural zones; they are used as an indicator group of microarthropods in the study of natural landscapes and anthropogenically disturbed ecosystems. In the karst landscapes of the North, the oribatid mites are very poorly studied. The aim of this study was to investigate the diversity of soil types, plant communities, and oribatid mites in karst relief forms in the conditions of the northern taiga forests. The material was collected in July 2020 in the karst landscapes of Timan Ridge, found in the European northeast of Russia. The research sites were located in the profile of the karst crater and in the profile of the slope in the Ukhta River Valley. A sedge wetland community, and pine–bilberry–green-moss forest, located in the depression between glacial hills and uplands were also examined. A total of seven sites were examined. Geobotanical descriptions were made by standard methods, descriptions of the soil profile, and samples of the soil microfauna; 12 in each site were collected. A total of 51 oribatid mite species from 39 genera and 31 families were found. The highest taxonomic diversity of oribatids was noted in forest phytocenoses located in the upper part of the karst crater slope, the lower part of the karst crater slope, and on rock outcrops in the lower part of the slope in Ukhta river valley. Ordination of the oribatid mite community by NMDS method showed the association of sites S3, S4, and S5 located on the slope of the karst crater in one group, and sites S6 and S7 located on a slope in the Ukhta River Valley, as well as S2 (pine–bilberry–green-moss forest located in the depression between glacial hills and uplands), in another group. The swamp community was located separately from other communities. Species of oribatid mites, which created the specifics of each community, were noted. The specifics of the population of oribatid mites of karst landscapes were that along with the features of fauna, characteristic of for zonal north-taiga forests (the predominance of polyzonal widespread species) were found in the “conditionally southern” species, the main area of distribution of which is located in lower latitudes. The study provides the basis for future studies of poorly known oribatid mites of karst landscapes of Northern Europe.
