    Isoenzyme diversity and differentiation of Marsh Scotch pine (Pinus sylvestris L.) population in the Western Siberia
: материалы временных коллективов / A. Ya. Larionova, A. K. Ekart // Eurasian Journal of Forest Research. - 2011. - Vol.14-1. - С. 21-28. - Библиогр. в конце ст.

Аннотация: Genetic diversity and defferentiation of Scotch pine populations situated on eutrophic, mesetrophic, oligotrophic swamps and on dry land in south-taiga subzone of Western Siberia lowland (Tomsk region) were srudied on the basis of allozyme variation analysis at 20 loci. The most essential distinctions in genetic structure were revealed between populations of Scotch pine growing under contrast conditions of water-mineral nutrition on eutrophic and oligotrophic swamps as well as between populations situated on the various oligotrophic swamps. The obtained results testify to considerable genetic heterogeneity studied in Tomsk region of marsh populations of Scotch pine.

УДК

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.

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.

    Impacts of Forest–Peat Fires on Soils and Their Influence on Carbon Losses in Phytogenic Microelevations of Mountain Swamps in the Southern Part of Central Siberia
/ T. T. Efremova, A. V. Pimenov, S. P. Efremov, A. F. Avrova // Contemp. Probl. Ecol. - 2021. - Vol. 14, Is. 3. - P279-289, DOI 10.1134/S1995425521030057 . - ISSN 1995-4255
Аннотация: Abstract: An assessment of the degree of contrast in the physicochemical properties of pyrogenic peat soils and fire-induced carbon losses 20 years after a major fire that partially destroyed a swamp spruce forest (Picea obovata Ledeb.) located within a complex of small river valleys in Kuznetsk Alatau, Republic of Khakassia, is made. The area affected by the fire is currently occupied by a shrub–sedge–green moss–hypnum birch forest (Betula pubescens Ehrh.) belonging to the group of short-term–secondary postfire grass forests. The pyrogenic peat soils (i.e., mechanical and chemical underburning) that formed as a result of passive smoldering (i.e., thermal impact below the ignition point) feature a high variability of physicochemical parameters (Cv = 26–37%). The application of multivariate statistical analysis techniques (cluster, discriminant, and canonical analysis) has made it possible to distinguish and statistically substantiate four clusters that correlate with the series of pyrogenic peat soils. Organic carbon makes the greatest (83%) input into the total contribution of chemical parameters to the differentiation of clusters, while the input of the volumetric water content is significantly less (15%). Based on the diversity and abundance of fire traces in the profile of pyrogenic peat soils, the distinguished clusters have been conditionally associated with slight, moderate, medium, and strong thermal impacts. Proportionally to the fire impact intensity, the soil clusters are enriched with ash components by 1.6–2.7 times (the ash content varies from 18.9 to 77%) and compacted by 2.2–4.3 times (the bulk weight reaches 0.147–0.421 g/cm3), while their pH value gradually changes from 6.8 to 7.6. A new approach to assessing carbon losses that occur in the course of passive peat smoldering is proposed. The new approach is based on the difference in the carbon content before and after the fire; it supplements the traditional method based on the peat-deposit incineration depth. The additional carbon losses in the 0- to 20-cm layer of pyrogenic peat soils vary in the range from 1.6 to 4.0 kg/m2, which is equivalent to 5.9–14.8 kg/m2 in CO2 emissions. The data on additional carbon losses at the stage of passive peat deposit smoldering are presented for the first time. © 2021, Pleiades Publishing, Ltd.

Аннотация: For the first time, using the example of a key object of the peat river valleys of the Kuznetsk Alatau occupied by spruce forests, it is shown that swamp waters are clearly differentiated by the content of the main ions due to forest-peat fires. Swamp waters objectively form three groups: (1) waters of the original type of mineral nutrition (fresh, soft), (2) waters of peatland covered by a medium fire (fresh, hard), (3) waters of peatland covered by a high fire (slightly saline, very hard). Magnesium ions and bicarbonates have the highest discriminating power (95%) in the determination of swamp waters. The swamp waters of the post-pyrogenic peatland do not lose the ratio of the main ions, which is similar to waters of the original type, and retain the hydro-carbonate calcium-magnesium composition.

    Эколого-геохимическая оценка торфяных почв болотных ельников Кузнецкого Алатау
[Текст] / Т. Т. Ефремова, О. А. Шапченкова, С. П. Ефремов, А. Ф. Аврова, М. В. Седельников // Сибирский лесной журнал. - 2022. - № 4. - С. 14-25, DOI 10.15372/SJFS20220402 . - ISSN 2311-1410

Аннотация: Исследованы лесные торфяные почвы заболоченных речных долин восточного макросклона Кузнецкого Алатау. Выявлено сильное варьирование ( С v 42-88 %) содержания макро- и микроэлементов в слое современных почв (0-30 см). Средневзвешенное количество (с учетом мощности горизонтов почв и площадей торфяных массивов) в пределах орографического профиля 1087-573 м н. у. м. составляет (мг/кг): Fe8623 > Al7295 > Mn335 > Sr230 > Zn37.8 > Cr15.4 > Cu13.2 > Ni9.9 > Pb4.6 > Co3.4 > Cd0.21. Методами многомерного статистического анализа выполнено структурирование торфяных почв по содержанию зольных элементов в три кластера, соответствующие высотным отметкам 1087, 832-622, 573 м н. у. м. Наибольшими дискриминирующими возможностями обладают Zn и Fe (82.6 %). Меньшую долю различия обеспечивают Cu, Ni (17.4 %). Топографические ряды долинных торфяных почв определяются гидрогеохимической зональностью подземных вод, а также выносом элементов латеральными миграционными потоками. Впервые статистически обоснованы границы высотных поясов торфяных почв по содержанию минеральных элементов и охарактеризован геохимический состав выделенных экотопических рядов (кластеров) почв. В почвах автономного ландшафта (высокогорья) аккумулируется только Pb и Cd. По сравнению с ним в кластере почв среднегорья количество большинства зольных элементов увеличивается в среднем в 2 раза. В низкогорье интенсивность аккумуляции несколько ослабевает. В почвенном профиле радиальная геохимическая миграция Fe как характерного элемента болот с большей силой положительно связана с зольностью торфяного субстрата, Sr - с реакцией среды, Cu и Mn - с фульвокислотами. В текущий период не выявлено техногенной деградации торфяных почв восточных отрогов Кузнецкого Алатау. Эколого-геохимические особенности горных торфяных почв согласуются с характеристикой естественных биогеохимических провинций юга Центральной Сибири, в пределах которых они развиваются.
The studies were carried out in forest peat soils of swampy river valleys of the eastern macroslope of the Kuznetsk Alatau. The content of macro- and microelements in the layer of modern soils (0-30 cm) varies greatly (Cv 42-88 %). The weighted average amount (taking into account the thickness of soil horizons and peat areas) within the orographic profile of 1087-573 m a. s. l. is: Fe8623 > Al7295 > Mn335 > Sr230 > Zn37.8 > Cr15.4 > Cu13.2 > Ni9.9 > Pb4.6 > Co3.4 > Cd0.21, mg/kg. The methods of multidimensional statistical analysis have been used to structure peat soils according to the content of ash elements into three clusters corresponding to altitudinal gradient - 1087, 832-622, 573 m a. s. l. Zn and Fe have the greatest discriminating ability (82.6 %). A smaller share of the difference is provided by Cu, Ni (17.4 %). The topographic series of river valley peat soils are determined by the hydrogeochemical zonality of groundwater, as well as the removal of elements by lateral migration flows. For the first time, the boundaries of the vertical altitudinal zonality of peat soils are statistically were proved by the content of mineral elements and the geochemical composition of the selected ecotopic series (clusters) of soils is characterized. Only Pb and Cd accumulate in the soils of the autonomous landscape (highlands). In comparison with it, in the cluster of soils of the middle highlands, the amount of most ash elements increases by an average of 2 times. In the low mountains, the intensity of accumulation weakens somewhat. In the soil profile, the radial geochemical migration of iron as a characteristic element of swamps is more strongly positively correlated with the ash content of the peat substrate, strontium - with the soil pH, Cu and Mn - with fulvic acids. In the current period, no technogenic degradation of peat soils of the eastern macroslope of the Kuznetsk Alatau has been detected. The ecological and geochemical features of mountain peat soils are consistent with the characteristics of the natural biogeochemical provinces on the south of Central Siberia, within which they develop.
