Abstract

The studies were carried out on the territory of the Kindasovo forest-bog research station of the Karelian Research Center, Russian Academy of Sciences, located in the middle taiga subzone (61°48′ N and 33°35′ E). The experiments were carried out in the Nenazvannoe natural mesoeutrophic bog of the aapa type in seven permanent bog areas located in different ecological and coenotic conditions. The paper presents long-term results (from 10 to 38 years) of studies of the dynamics of annual growth of 11 widespread hygro- and hydrophilic species of sphagnum mosses. Based on fluctuations in the average annual growth data during the years of study, the largest increases were observed for Sphagnum riparium (140 mm) and S. obtusum (93 mm), growing in heavily watered bog areas and not withstanding drying out; medium growths of S. fallax (65 mm), S. subsecundum (57 mm), S. majus (42 mm), S. balticum (36 mm), and S. warnstorfii (28 mm) are found in low-flow watered bogs, hollows, and on carpets; the lowest growth was shown for S. divinum (17 mm), S. centrale (15 mm), S. papillosum (12 mm), and S. fuscum (8 mm), growing on ridges, low hummocks, and carpets under conditions of sharply variable conditions hydration. A correlation analysis to study the influence of precipitation and average temperature on the annual growth of sphagnum mosses did not show any significant dependence of moss growth on temperature during the growing season. For S. fuscum, S. obtusum, and S. warnstorfii, negative dependences on the temperature of individual months are observed in different months of the growing season. Precipitation during the growing season is the main factor determining the dependence of the annual growth of sphagnum mosses. A significant dependence of annual growth on precipitation during the growing season was shown for species S. obtusum, S. papillosum, S. centrale, S. fallax, and S. subsecundum, while the significance was weak for S. divinum, S. fuscum, and S. majus.

对卡累利阿中部泰加地区斯芬格伦属苔藓年生长情况的长期研究结果

摘要研究是在位于中泰加亚区（北纬 61°48′，东经 33°35′）的俄罗斯科学院卡累利阿研究中心金达佐沃森林沼泽研究站境内进行的。实验是在位于不同生态和共生条件下的七个永久性沼泽区的 Nenazvannoe aapa 型天然中营养沼泽中进行的。本文介绍了对 11 种广泛分布的吸湿和亲水性石炭藓年生长动态的长期研究结果（10 至 38 年）。根据研究期间平均年生长量数据的波动情况，观察到生长在水量充足的沼泽地区且不耐干旱的 Sphagnum riparium（140 毫米）和 S. obtusum（93 毫米）的年生长量增幅最大；生长量中等的 S. fallax（65 毫米）、S. subsecundum（57 毫米）、S. majus（42 毫米）、S.S.divinum（17 毫米）、S.centrale（15 毫米）、S.papillosum（12 毫米）和 S.fuscum（8 毫米）的生长量最低，它们生长在山脊、低矮的沼丘和地毯上，水合条件变化剧烈。为研究降水量和平均气温对泥炭藓年生长量的影响而进行的相关分析表明，在生长季节，泥炭藓的生长量与气温的关系并不明显。对于 S.fuscum、S.obtusum 和 S.warnstorfii，在生长季节的不同月份观察到与个别月份的温度呈负相关。生长季节的降水量是决定石炭藓年生长量的主要因素。S.obtusum、S.papillosum、S.centrale、S.fallax 和 S.subsecundum等物种的年生长量与生长季节降水量有明显的相关性，而 S.divinum、S.fuscum 和 S.majus 的相关性较弱。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
