The study aims to characterize CO₂ emission from the soil surface of mature and maturing middle taiga pine forests, taking into account forest conditions. The objects of the study were sphagnum, blueberry, and lingonberry-lichen pine forests located on the territory of the forest field stations of the Institute of Biology, Komi Scientific Center, Ural Branch, Russian Academy of Sciences (Komi Republic, Russia). In 2008–2017, CO₂ emissions were measured by a gas analyzer LI-COR 8100. A brief description of weather conditions for the study period is given. During the snow-free period, relatively high values of CO₂ flux from the soil of pine forests were detected in July (sphagnum pine forests: 1.9–2.9 g C m^–2 day^–1) and August (blueberry and lingonberry-lichen pine forests: 2.5–6.6 g C m^–2 day^–1). The interannual variability of average monthly CO₂ emission and the influence of weather conditions were determined. A close positive relationship between the rate of carbon dioxide emission and soil temperature was revealed (<i>R</i>² = 0.49–0.77). The correlation of CO₂ emission with soil moisture was weak. During the summer months, 188–442 g C m^–2 was released into the atmosphere from the soil of the blueberry pine forest; during the growing season (May 1–September 30), 279–563 g C m^–2; during the snow-free period (May 1–October 31), 308–583 g C m^–2, which is 1.5–1.8 times higher than in sphagnum and lingonberry-lichen pine forests during the snow-free (<i>p</i> = 0.014) and growing season (<i>p</i> = 0.020) periods. No significant influence of forest conditions on C–CO₂ losses in the summer months was found (<i>p</i> = 0.106). Lichen and sphagnum pine forests were comparable in terms of the C–CO₂ flux from the soil surface both during the growing season and the snow-free period (<i>p</i> &gt; 0.05). The data presented are important in determining the expenditure part of the carbon balance in forest ecosystems in the European northeast of Russia.</p>","PeriodicalId":49586,"journal":{"name":"Russian Journal of Ecology","volume":"23 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140885775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that the beginning of the stands colonisation by the grey heron can be quite accurately determined by analysing the dynamics of the annual tree rings parameters, especially the width of their late layer and the optical density of wood (the values of the former are lower in the control stand, and of the latter one are higher there). Grey heron colonies begin to appear in pine forests as early as 10–12 years old, when the height of the trees reaches 5–6 m, and the diameter of the trunk at a height of 1.3 m from the soil surface is only 7–8 cm. In the first 15–20 years, they have a positive influence on the annual growth of trees, especially on the width of the late layer of wood and the thickness of the cell walls, but then the picture changes to the opposite. The total residence time of heron colonies in one place is about 35–40 years, after which they move to new places due to the forest stands coming into disarray or even facing complete destruction. To reduce the likelihood of the appearance of grey heron colonies, which in many cases have a negative impact on the state of forest biogeocoenoses, it is necessary to stop creating pure pine forests near water bodies, giving preference to spruce, birch, poplar, or linden-oak plantations.</p> </span>","PeriodicalId":49586,"journal":{"name":"Russian Journal of Ecology","volume":"37 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139756026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aims at analysing the species and community diversity of the floodplain forests depending on the habitat conditions and their position in the successional series. Geobotanical characteristics of communities in chosenia (<em>Chosenia arbutifolia)</em>, Mongolian poplar (<em>Populus suaveolens</em>), willow (<em>Salix udensis,</em> narrow-leaf willow <em>S. schwerinii</em>), and alder (<em>Alnus hirsuta</em>) forests were displayed by dominant-determinant classification. The community diversity of the floodplain forests is represented by 19 associations, grouped into 5 series. The floristic composition and structure of the floodplain forests' communities were characterized, the Shannon and Pielou indices, species richness, species percentage coverage, and layer density were estimated. Compared to the forests of the Kamchatka Peninsula, the floodplain forests of North-East Russia were characterized by low syntaxonomic diversity and represented by floristically poor communities. The structure and dynamics of the floodplain forests' communities are discussed. The indicators of species diversity and evenness were calculated for each of the studied communities. The lowest Shannon index appeared to the pioneer chosenia communities with sparse herb cover, found on recent pebble sediments; the highest index was found for herb-moss poplar forests that occupied the highest elevations of the floodplain. The rest of the associations had intermediate values of the Shannon index. The species diversity tended to increase over the sequence of alluvial succession. The obtained data suggested that the species diversity of communities might increase during succession and depend on habitat floodplain regime and alluvial index decrease.</p> </span>","PeriodicalId":49586,"journal":{"name":"Russian Journal of Ecology","volume":"168-169 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139756173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
