Identifying the patterns of dynamics of natural populations of woody plants at the stage of their renewal is one of the main problems of forest ecology. The reforestation process is determined by both the dynamics of seed production and the specificity of seed dispersal of forest tree species. The five-needled pine renewal the Cembrae subsection wi...

The aim of the research is to reveal the relationship between the age and composition of the forest stand and the regeneration of Picea obovata Ledeb. and Abies sibirica Ledeb. Null hypothesis: we can estimate young generations of P. obovata and A. sibirica under the forest canopy based on the composition and age of the forest stand. The studies co...

The conservation of biodiversity and ecosystem sustainability is essential for human well-being. An important tool for addressing this issue is ecological indicators. This overview document examines recent studies covering the period 2018–2022 that use the values of the Landolt indicator as one of the analysis methods. The total number of records e...

The ecological indicator values are the most common and sufficiently effective method of habitat assessment. The aim of our research review is to analyze current studies from 2020 to 2022 in which researchers have used Ellenberg indicator values to address a variety of problems. We limited the study to papers that are published in journals indexed...

Climate is one of the key drivers of the plant community’s structure and trends. However, the regional vegetation-climate features in the ecotone have not yet been sufficiently studied. The aim of the research is to study features of Pinus sibirica Du Tour germination, survival, and growth in the mountain tundra of the Northern Urals against the ba...

The article describes the approaches and features of classification of forests, habitats and vegetation at the Pan-European level on the example of the classification of European forest types (EFT), the EUNIS habitat classification and the Europe vegetation classification created by the phytosociologists of the European Vegetation Survey (EVS). The...

Due to global climate change and increased forest transformation by humans, accounting for the dynamics of forest ecosystems is becoming a central problem in forestry. We reviewed the success of considering vegetation dynamics in the most influential ecological forest classifications in Russia, the European Union, and North America. Out of the vari...

The investigation of typological patterns in dynamics of herb layer biodiversity after logging in the Ural Mountains was carried out. Seven predominant types of pine ecosystems were studied in the following variants: 160-year- old forest and its 2-6-year-old cutting. Statistically significant differences in species saturation between conditionally...

Included is the review of forest typology aimed at issues related to climate-driven dynamics of vegetation. Problem definition and key research were performed under extreme conditions for trees (upper tree-line ecotone). Study of climate factor impacts on forest ecosystems in taiga zone conditions that are optimal for arboreal plants has a number o...

The problem of preserving biodiversity in the face of human influence and climate change is one of the most pressing problems of modern ecology. The aim of the study is to identify the characteristics of herb SAD for various mountain pine forest types in the Middle Urals. Studies conducted in various types of pine forests have shown that the SAD me...

The processes of natural reforestation play a crucial role for the preservation of primary coniferous forests and the success of their restoration after catastrophic impacts. The objective of our research was to identify the features of the natural renewal of the main coniferous forest-forming plants under the canopy of stands in the mountains of t...

The adaptive capacity of ecosystems is a key to maintaining ecosystem functions and preserving biodiversity at all levels. The research was carried out in the western Southern Ural low-hill terrains (Russia). We analyzed distributions of above-ground biomass of herb layer species in the primary spruce, long-term secondary birch 20-35-year forests,...

The article presents the results of assessing the element mobility (chemical elements and compounds) from the copper smelting slag recycling waste into brown forest soils (Haplic Cambisols) of the southern taiga district in Middle Urals, Russia. The copper smelting slag recycling waste was obtained by crushing the cast slag of the Sredneuralskiy Sm...

Paper describes key elements of a genetic approach to classification of forest types – one of the original forest typological research directions in Russia summarizes the results of research over the hundred-year period of formation and development of this promising (from the point of view of sustainable management of natural resources) scientific...

Adaptation of plant communities is an important factor for maintaining their functioning and stability in changing conditions. The aim of our research is study of the effect of soil moisture regime on the species richness and biomass of the herb layer for old-growth coniferous forests in the Ural Mountains (Russia). The research has been carried ou...

Research subject . In this paper, we investigate the possibility of recycling wastes from copper smelting facilities in brown mountain forest soils. The research object was “technical sand” obtained at the Sredneuralsky copper smelter as a byproduct. This finely dispersed material rich in copper, zinc and other chalcophilic elements undergo mechani...

The purpose of the research is to identify the effect of soil factor on the ability of Scots pine to adapt to technogenic pollution based on comparative analysis of radial increment of the species which grows on soils of different fertility. The null hypothesis that soil fertility is a significant factor for adaptation was tested. The research area...

For nominally indigenous forests of the Trans-Urals hilly piedmont province of the Middle Urals, the species composition and productivity of the lower layers – as an adaptation to different humidity regimes – were studied. The research is based on three forest types (by the principles of genetic typology): cowberry pine forest, grass pine forest, a...

Based on the results of long-term investigations, we present quantitative data on the biodiversity of conditionally native forests in the western low mountains of the Southern Urals and the Trans-Ural hilly foothill province of the Middle Urals. Available information about forest types is supplemented with information on the productivity and specie...

The possibilities of the Catastrophe Theory for predicting the dynamics of forest ecosystems and developing scenarios for sustainable forest management are discussed. The main features of the approach are described. The achievements and difficulties of application for the Catastrophe Theory in scientific research have been discussed. Examples are g...

In Russia, boreal forests are forests that grow in the tundra and forest tundra zones, subzones of the northern and middle taiga and partially in the southern taiga. The most important conifer trees of the boreal forests of Russia are pine, also called Pinus sylvestris L., spruce or Picea obovata Ledeb. and larch or Larix sibirica Ledeb. All of the...

Forest trees and shrubs play vital ecological roles, reducing the carbon load from the atmosphere by using carbon dioxide in photosynthesis and by the storage of carbon in biomass and wood as a source of energy. Autoecology deals with all aspects of woody plants; the dynamism of populations, physiological traits of trees, light requirements, life h...

The purpose of this paper is to study dynamics patterns of the Ural (Russia) forest ecosystems to allow their biodiversity conservation in the context of anthropogenic impact. One of our objectives was to test the hypothesis that external factors cause splitting-up of natural forests and their replacement by a range of successional series. Our rese...

For the mountain forests of the Middle Urals (Russia) recovery of tree stand after clear-cuttings was studied. Two options of the drained habitats have been studied: steep slopes of the southern exposition with small stony soils and the lower parts of gentle slopes with thick soils. For the description of biomass dynamics of pine (Pinus sylvestris...

Forest typology holds the central position in modern forestry. We give an overview of research on forest typology in Russia. Forest typology in Russia actively developed and improved with respect to requests forestry throughout the entire period of its existence. It remains the necessary basis for preserving the biodiversity of land ecosystems and...
