Перевод заглавия: Microbiological diagnostics of soil stage in the phyllosphere of the woodland ecosystem of Siberia
Аннотация: Показано, что диагностику состояния лесных почв при действии пожаров и рубок леса целесообразно осуществлять по оценочным показателям шкалы диапазонов численности основных эколого-трофических групп микроорганизмов (ЭКТГМ), коэффициентам микробиологической активности, резерва и флуктуации численности, метаболизма. Оценена степень влияния техногенных выбросов предприятий на лесную подстилку, почву и филлосферу по численности ЭКТГМ на диагностических средах и их ферментативной активности, выраженной через функции желательности.

Аннотация: It is shown that the diagnostics of the stage of woodland soils affected by wildfires and forest cuts can be determined by the evaluation indexes of the range of the scale of abundance of typical ecologic-and-trophic groups of microorganisms (ECTGM), microbiological activity coefficients, reserve and abundance fluctuations, and metabolism. The degree of impact of the technogenic emissions on the forest cover, soil, and phyllosphere according to ECTGM abundance on the diagnostic environments and their fermentative activity is expressed with the help of an advisability functional relation.

Microbiological diagnostics of the status of pyrogenically changed pine forests in the Lower Angara River basin

Аннотация: The structure and functions of the microbial complexes in the soils after surface fires of different intensity were studied. The fires of high and medium intensity were found to lead to a significant decrease in the number and functional activity of microorganisms participating in the nitrogen-carbon cycle. The degree of changes in the postfire status of the soil microbocenoses was revealed to be related to the joint action of pyrogenesis and the hydrothermal conditions at the moment of the fire rather than to the fire intensity. The favorable combination of the elevated soil moisture and soil heating stimulates the microbiological processes of organic matter mineralization, thus, improving the forest-growing conditions for the pine forests. The microbial biomass, basal respiration, and the microbial metabolic coefficient are shown to adequately reflect the postfire status of the microbial complexes.

Diversity and distribution of leaf mining insects on birches (Betula spp.) in Siberia
/ N. I. Kirichenko [et al.] // Entomol. Rev. - 2017. - Vol. 97, Is. 2. - P183-198, DOI 10.1134/S0013873817020051

Аннотация: The diversity and distribution of leaf mining insects developing on birches (Betula spp.) in Siberia were reviewed based on published records and our observations. Analysis of the literature revealed 52 species of leaf miners recorded as feeding on different Betula species in Siberia. Among them, three species were listed under different names and six species were erroneously recorded as birch consumers. Thus, the revised list of birch leaf miners contains 44 species. Five moth and four sawfly species are mentioned in the literature as pests of Betula. Four sawflies are known to be invasive in North America. Our collections comprised 25 species, including the micro-moth Stigmella continuella (Lepidoptera, Nepticulidae), a new species for Siberia found in Novosibirsk. Immature stages of 15 species were identified using DNA barcoding. Twenty species were recorded from several regions of Siberia for the first time. The dominant group is Lepidoptera (31 species), followed by Coleoptera (7), Hymenoptera (5), and Diptera (1). Two-thirds of all the known leaf miners develop exclusively on birches; the remaining species also colonize alders (Alnus, Betulaceae), some Rosaceae, Salicaceae, and Ulmaceae. In our observations, the majority of insects (96%) developed on B. pendula. About half of them were also observed on the East Asian birches B. dahurica, B. divaricata, B. costata, B. ermanii, and B. gmelinii; five species were found on the North American birches B. occidentalis and B. papyrifera. All the leaf mining species listed in our paper for Siberia also occur in Europe. The similarity between the miner faunas of these regions is discussed and it is warned about possible errors in diagnostics of the Siberian species using the keys and catalogues for the European fauna. The importance of DNA barcoding in the study of the local insect faunas of poorly explored regions is also emphasized. © 2017, Pleiades Publishing, Inc.

Аннотация: Reforestation is very important in controlling land degradation and desertification. It has been established that the early diagnostics of the forest-growth conditions of soils and sustainability of forest plantations can be estimated by biogenic factors, such as the structure, dynamics, and functional activity of microbial complexes closely related to agrochemical soil indicators. The survival and sustainability of experimental forest plantations that were established in 1975 to 1978 on erosion-prone lands in the coastal zone of Shira Lake (Khakassia) have been studied. The forest growing properties of soils and the transformation of their fertility under the influence of stands have been evaluated.

Аннотация: По типу линейной функции установлены количественные связи активной кислотности (рН<sub>Н<sub>2</sub>О</sub>) торфяных почв с величиной обменной (рН<sub>KCl</sub>) и гидролитической (общей) кислотности, содержанием обменных катионов и щелочноземельных оснований, а также со степенью насыщенности основаниями. Приведены коэффициенты полученных уравнений регрессии. Доказаны высокие прогностические возможности регрессионных моделей на примере независимых данных. Применение регрессионных уравнений избавляет от выполнения трудоемких аналитических работ, что позволяет оперативно осуществлять классификацию болот и торфяных почв по химическому принципу - насыщенности щелочноземельными основаниями и величине рН. Индикаторная роль ботанического состава может заслуживать доверия при условии невысокой степени разложения торфа и специальных знаний морфологии и анатомии сфагновых мхов и сосудистых болотных растений.
The quantitative relationships of active acidity (pH<sub>H<sub>2</sub>O</sub>) of peat soils with the value of exchange acidity (pH<sub>KCl</sub>), nonexchangeble (total potential) acidity (1M CH<sub>3</sub>COONa extract), and the content of exchange cations and alkaline-earth bases, as well as the degree of bases saturation were established by the type of linear function. The coefficients of the regression equations are given. Using independent data, we proved the high predictive capability of regression models. Using the regression equations eliminates the time-consuming execution of analytical works, which allows to quickly classification the wetlands and peat soils on the chemical principle - saturation of alkaline-earth bases and pH value. The indicator role of the botanical composition may be credible provided the low peat decomposition degree and special knowledge of morphology and anatomy of sphagnum mosses and vascular bog plants.

Formal Criteria for the Humus Status of Mountainous Peat Soils in Altitudinal Zones

Аннотация: Cryogenic oligotrophic (Hyperdystric Cryic Fibric Histosols), oligomesotrophic (Dystric Fibric Histosols), mesoeutrophic (Oligeoeutric Fibric Histosols), and eutrophic (Hypereutric Fibric Histosols) peat soils were studied on the eastern slopes of the Kuznetsk Alatau Ridge (Republic of Khakassia). Their altitudinal differentiation was examined, and clustering according to the qualitative and quantitative composition of organic matter was performed. The most informative indicators of similarity and/or differences between the clusters were suggested. The group composition of organic matter was analyzed using acid and alkaline extractions. Multivariate statistical analyses (cluster, discriminant, and canonic) were applied for evaluation of the humus status. Indicators of organic matter status, which are significant for discrimination form two discriminant functions. Function 1 discriminates between the clusters (80%) and includes the indicators characterizing the depths of peat soil transformation: humification degree ( n-ary sumation HA + n-ary sumation FA), type of humus (C-HA/C-FA ratio), and ratio between the fractions of humic acids extracted by 0.02 N NaOH and 0.1 N NaOH (C-0.02 n NaOH/C-0.1 n NaOH). Function 1 clearly separates clusters of permafrost-affected oligotrophic peat soils of the alpine tundra zone (>1460 m a.s.l.) from oligo-mesotrophic peat soils of the subalpine zone (1087 m a.s.l.). Function 2 discriminates (at the 16% difference level) the clusters of peat soils of the forest zone-meso-eutrophic peat soils of the taiga zone (832 m a.s.l.) and eutrophic peat soils of the subtaiga-forest-steppe zone (622-573 m a.s.l.); it also includes hemicellulose and cellulose-characteristics of the initial state of peat-forming plants. The humus status of the mountainous peat soils corresponds to their diagnostics according to the base saturation and pH criteria and reflects a general pedogenetic trend in mountains: an increase in the humus content in soils with the altitude, which was earlier shown for mineral soils.

Аннотация: Quantitative relationships between the active acidity of peat soils on the one hand and their exchange acidity (pH(KCl)), nonexchangeble (total potential) acidity (1M CH3COONa extract), contents of exchange cations and alkaline-earth bases, and base saturation degree, on the other hand, have been identified in the form of a linear function. Coefficients of the resultant regression equations are provided. The high predictive capability of the produced regression models is proven using independent data as examples. The use of regression equations eliminates the need for time-consuming chemical analytical works, thus making it possible to operatively classify wetlands and peat soils on the basis on their chemical properties: saturation with alkaline-earth bases and pH value. The botanical composition may also be used as a reliable indicator, provided that the degree of peat decomposition is low and subject to special knowledge of morphology and anatomy of sphagnum mosses and vascular swamp plants.

Аннотация: Исследован качественный и количественный состав органического вещества горных торфяных почв криогенных олиготрофных (Hyperdystric Cryic Histosols), олиго-мезотрофных (Orthodystric Histosols), мезо-эутрофных (Oligeoeutric Histosols) и эутрофных (Hypereutric Histosols) восточного макросклона Кузнецкого Алатау (республика Хакасия). Изучена высотно-поясная дифференциация и выполнена объективная группировка (кластеризация) торфяных почв по гумусному состоянию, установлены наиболее информативные признаки сходства и/или различия кластеров. Проведены последовательный анализ группового состава органического вещества методом кислотной и щелочной экстракции, оценка по системе показателей гумусного состояния почв, многомерный статистический анализ (кластерный, дискриминантный, канонический). Значимые для дискриминации показатели состояния органического вещества формируют две дискриминантные функции. Первая обладает наибольшими дискриминирующими возможностями различать кластеры (80%) и включает показатели, которые характеризуют глубину преобразования торфяных почв: степень гумификации (∑ГК + ∑ФК), тип гумуса (отношение СГК/СФК), соотношение фракций гумусовых веществ (С0.02 н NaOH/C0.1 н NaOH). Функцией 1 дискриминируются кластеры торфяных почв высокогорья: мерзлотные олиготрофные альпийско-тундрового пояса (1460 м над ур. м.) и олиго-мезотрофные субальпийского пояса (1087 м). Вторая дискриминантная функция обеспечивает меньшую долю различия (16%) и включает показатели исходного состояния растений-торфообразователей: гемицеллюлозы и целлюлоза. Функцией 2 дискриминируются кластеры торфяных почв лесного пояса: мезоэутрофные горно-таежного пояса (832 м) и эутрофные подтаежно-лесостепного пояса (622–573 м над ур. м.).

Cryogenic oligotrophic (Hyperdystric Cryic Fibric Histosols), oligo-mesotrophic (Dystric Fibric Histosols), meso-eutrophic (Oligeoeutric Fibric Histosols), and eutrophic (Hypereutric Fibric Histosols) peat soils on the eastern slopes of the Kuznetsk Alatau Ridge (Khakassia Republic) were studied. Their altitudinal differentiation was examined, and their clustering according to qualitative and quantitative composition of organic matter was performed. The most informative indicators of similarity and/or differences of the clusters were suggested. The group composition of organic matter was studied using acid and alkaline extractions. Multivariate statistical analyses (cluster, discriminant, and canonic) were applied for evaluation of the humus state of soils. Significant indicators of the organic matter status form two discriminant functions. Function 1 discriminates between the clusters (80%) and includes the following indicators: humification degree (∑HA + ∑FA), type of humus (Cha/Cfa ratio), and ratio between the fractions of humic acids extracted by 0.02 N and 0.1 N NaOH (С0.02N NaOH/C0.1N NaOH). Function 1 clearly separates permafrost-affected oligotrophic peat soils of the tundra zone (>1460 m a.s.l.) from oligo-mesotrophic peat soils of the subalpine zone (1087 m a.s.l.). Function 2 discriminates between the clusters of peat soils of the forest zone—meso-eutrophic peat soils of the taiga zone (832 m a.s.l.) and eutrophic peat soils of the subtaiga–forest-steppe zone (622–573 m a.s.l.) at the 16% difference level. The humus status of the mountainous peat soils corresponds to their diagnostics according to the base saturation and pH criteria and reflects a general tendency for an increase in the soil humus content at higher altitudes, which has earlier been shown the mineral soils

Аннотация: Исследован качественный и количественный состав органического вещества горных торфяных почв криогенных олиготрофных (Hyperdystric Cryic Histosols), олиго-мезотрофных (Orthodystric Histosols), мезо-эутрофных (Oligeoeutric Histosols) и эутрофных (Hypereutric Histosols) восточного макросклона Кузнецкого Алатау (республика Хакасия). Изучена высотно-поясная дифференциация и выполнена объективная группировка (кластеризация) торфяных почв по гумусному состоянию, установлены наиболее информативные признаки сходства и/или различия кластеров. Проведены последовательный анализ группового состава органического вещества методом кислотной и щелочной экстракции, оценка по системе показателей гумусного состояния почв, многомерный статистический анализ (кластерный, дискриминантный, канонический). Значимые для дискриминации показатели состояния органического вещества формируют две дискриминантные функции. Первая обладает наибольшими дискриминирующими возможностями различать кластеры (80%) и включает показатели, которые характеризуют глубину преобразования торфяных почв: степень гумификации (∑ГК + ∑ФК), тип гумуса (отношение СГК/СФК), соотношение фракций гумусовых веществ (С0.02 н NaOH/C0.1 н NaOH). Функцией 1 дискриминируются кластеры торфяных почв высокогорья: мерзлотные олиготрофные альпийско-тундрового пояса (1460 м над ур. м.) и олиго-мезотрофные субальпийского пояса (1087 м). Вторая дискриминантная функция обеспечивает меньшую долю различия (16%) и включает показатели исходного состояния растений-торфообразователей: гемицеллюлозы и целлюлоза. Функцией 2 дискриминируются кластеры торфяных почв лесного пояса: мезоэутрофные горно-таежного пояса (832 м) и эутрофные подтаежно-лесостепного пояса (622–573 м над ур. м.). Гумусное состояние горных торфяных почв соответствует их диагностике по принципу насыщенности основаниями и величине рН, а также отражает общие признаки горного почвообразования – увеличение гумусированности с высотой, установленной ранее для почв минерального ряда
