On the one hand, climate changes affect biodiversity, on the other hand, it is biodiversity, as a provider of all ecosystem functions, underlies the mechanisms of adaptation to these changes. This paper aims to discuss scientific questions about the links between biodiversity and climate-regulating functions of forests, and to outline the prospects for these studies. It is shown that studies of the influence of plant and animal species – ecosystem engineers on forest ecosystem’s functioning, including climate-regulating processes and functions, are quite numerous. However, studies of the combined effects of the diversity of biota belonging to different trophic levels and groups on climate-regulating functions of forests of different types/different stages of succession are not carried out. In such studies, it is important to take into account both taxonomic, including genetic, and functional biodiversity as well as structural diversity of forests. Various concepts of forest management taking into account the conservation and restoration of biodiversity are considered. An important aspect of this problem is the assessment and prediction of relationships (synergy or trade-offs) between climate-regulating and other ecosystem functions of forests with different levels of biodiversity functioning in natural conditions and under the combined impact of natural and anthropogenic factors, including climate change, fires, and forestry regimes. It is shown that a promising approach to assessing and predicting the dynamics of relationships between different ecosystem functions of forests is the integration of mathematical models.","PeriodicalId":237008,"journal":{"name":"Forest science issues","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128609560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the area of damages in the country as a whole is higher than the average annual values, the scale of pyrogenic carbon emissions is lower than the average annual values and in absolute terms corresponds to 2016. There has been an increase in fire Carbon emissions since 2012.

Some authors claim that earthworm activities result in decreased carbon accumulation. Other studies show that earthworms contribute to soil carbon accumulation. At the same time, many studies do not take into account the differences between trophic and digging activity of different morpho-ecological groups of earthworms in different soil horizons. The objective of this study was to carry out differentiated assessment of the impact of different morpho-ecological groups of earthworms on carbon accumulation and correspondent soil parameters (nitrogen content and С/N ratio) throughout the change in forest succession status. Field operations were performed in the spring and summer of 2016 and 2018 in three regions: Bryansk Oblast (Bryansk Forest reserve), Moscow Oblast (Moskva–Oka plain, Valuyevsky urban forest) and Northwest Caucasus (Krasnodar Krai, Apsheron forestry; Republic of Adygeya, Caucasian Biosphere Reserve). Three main stages of coniferous-broadleaf forest restoration after clear cuttings were identified in each region. Three test plots 50х50 m were allocated for each stage; geobotanical and soil descriptions as well as earthworm registration were carried out on each plot. It was found out that during the change in forest succession status the species composition and the set of morpho-ecological groups of earthworms became more complicated, but there was no successive replacement of any groups with others. Ambiguous effects of different morpho-ecological groups of earthworms on carbon accumulation in forest soils were revealed. Negative correlation was found between the total biomass of earthworms feeding on the soil surface (epigeic, epi-endogeic and anecic species) and litter store. In the humus horizon, the biomass of epi-endogeic species was positively correlated with the content of carbon. C/N ratio and nitrogen content are unidirectionally correlated with the biomass of earthworms in the horizons of their activity: with an increase in the biomass of earthworms of different morpho-ecological groups, the C/N ratio decreases, and the nitrogen content increases.","PeriodicalId":237008,"journal":{"name":"Forest science issues","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127932992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fire regime determines conditions of occurrence, spread and long-term consequences of forest fires. A significant change in the fire regime in the natural complex may indicate at possible loss risks of the key components of the ecosystem. This study presents current and historical fire regimes mapping results for the Pechora natural reserve and its surroundings - Kurinsky and Yakshinsky forest districts. The input dataset consists of fire historical fires records for the area taken from several sources: historical fires dataset of the Pechora natural reserve covering period from the second half of the XIX century till nowadays, which was received from both satellite images interpretation and reserve’s records archive analysis; hot spots detected by airborne-based and ground-based means covering period from 1987 to 2011 and the dendrochronological reconstruction of fires in the pine forests of the reserve’s surroundings for a 600-year period. We applied a methodology of mapping forest ecosystems fire regimes at local level for mapping both current and historical fire regimes. The methodology is based on the LANDFIRE classification, which accounts for fires frequency and fires severity. Results analysis of historical fire regimes indicate the dominance of “less than 200 years” fire return rate, associated with low-to-moderate fire severity for the most of the area. As an exception, the mountainous part of the Pechora natural reserve is characterized by a long period of fire return rate. The analysis of current fire regimes has revealed long periods of fire recurrence in both the reserve area and the forest districts area. We also showed a human impact on the increase in fire frequency. An assessment of the deviation of current fire regimes from their historical values showed that current fire regimes are within their normal historical range in most of the study area.","PeriodicalId":237008,"journal":{"name":"Forest science issues","volume":"422 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133322775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smirnova, Doctor of Biological Sciences, is a prominent scientist in the field of plant demography, population biology, and forest ecosystem ecology. Professor Olga V. Smirnova’s edifice is based on ideas about the leading role of plant and animal populations in the organization of the biogeocenotic cover. In this case, it is implied that a continuous generational turnover in edificator (keystone species) populations is necessary to maintain the species and structural diversity in communities and ensure their sustainability. This system of views was influenced by Professor Alexey A. Uranov. The development of these ideas was consistent and gradual. First, Professor Olga V. Smirnova studied the biology of different plant species life forms. Examining their individual development, with identification of ontogenetic stages, is necessary for demographic research. She then developed the theory of coenopopulations as supraorganismal systems, which can self-sustain under different conditions. Finally, she developed the doctrine of biogeocenosis as a system of interacting populations and created the concept of anthropogenic transformation of the forest cover in the Holocene. Her contributions helped researchers to understand the mechanisms of the formation of modern zonality that are due to human activity.","PeriodicalId":237008,"journal":{"name":"Forest science issues","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122441689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spatial data were obtained on tree expansion on the fallow in 2005–2018, current tree canopy heights and its vertical growth, stem density, and canopy closure. The study revealed distinct spatio-temporal heterogeneity of tree overgrowth on the fallow. In the first years after land abandonment the most rapid regeneration and dispersal of trees occurred from the forests resulting in very dense but low tree cover adjacent to the forest. Later, tree overgrowth occurred in isolated hotspots and was characterized by very intensive vertical growth of the tree canopy.","PeriodicalId":237008,"journal":{"name":"Forest science issues","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123533665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
