Аннотация: The rate of lignin deposition, its content and composition, and molecular weight distribution of different stages of secondary wall thickening during tracheid development of both earlywood and latewood in Siberian larch (Larix sibirica Ldb.) were studied in the stems of 25-year-old trees. The cells of early and late xylem at different stages of secondary wall development were obtaint in late June and early in August, respectively. Lignification of the two types of wood was found to involve different dynamics. The intensity of lignin synthesis during earlywood formation increases gradually, reaching the maximum at the last stage of tracheid maturation. In contrast, lignin deposition in the course of latewood development is the highest only in the first stage of lignification and declines by the end of tracheid maturation. There were differences in the composition of alkaline oxidation products of lignin preparations at different development stages of early and late xylem. The amount of cell wall substances deposited before lignification in earlywood is larger than that in latewood.

Аннотация: This paper studies the structure and dynamics of the major pools of organic matter in clearings in the lichen pine forests of the middle taiga subzone of Yenisei Siberia, in the range of measurements of the international observatory Zotto, a high-tech research platform for long-term ( 30 years) monitoring of the atmosphere and climate changes. The contribution of phytocenoses at different stages of post-clearing succession in the process of deposition of atmospheric carbon is analyzed. In conjunction with the data on atmospheric measurements of a wide range of greenhouse gases carried out at the base of the observatory, the results of this work will be used for modeling the stocks and flows of carbon in forest ecosystems of Central Siberia.

Аннотация: The content and composition of alcohol soluble phenolic acids (PhAs) were studied during cell xylem growth in course of wood annual increment formation in the trunks of Scots pine. Cells of the cambium zone, two stages of expansion growth, and outset of secondary thickening zone (before lignification) within the period of formation of early wood xylem were subsequently isolated from trunk segments of 25-year-old trees with constant anatomical and histochemical control. The amount of free and bound forms of phenolic acids extracted from tissues by 80% ethanol, as well as their ethers and esters, were calculated both per dry weight and per cells. The substantial alteration in content, proportion of fractions and composition of acids has been found between the cambium zone and the outset of secondary thickening of tracheids, and the character of variation depended on the calculation method. The amount of free and bound PhAs and esters and especially ethers calculated per cell had increased at the first stage of extension growth, reduced at the second, and increased in the outset of secondary wall deposition. The pool of bound acids was more than acids by 2-5 times depending on the stage of development of the cells. Sinapic and ferulic acids dominate among free hydroxycinnamic acids. The composition and the content of hydroxycinnamic acids in esters and ethers also depended on the stage of development of the cells. p-Coumaric and sinapic acids were the main aglycons in ethers in the cambium and sinapic and caffeic acids were in the other stages. The esters from cambium included mostly p-coumaric acid and those at other stages of development were sinapic and ferulic acids. The esters included benzoic acid at the first stages of growth. The pool of these esters decreased from the first phase of growth until the outset of cell wall thickening. The level of free benzoic acid increased respectively.

Аннотация: Thallus morphology and element concentrations (S, Al, Fe, Sr, Mn, Ni, Zn, Cu, Pb, As, F, and Cl) were compared in samples of the fruticose lichen genus Usnea at two heights of the Abies sibirica canopy in the East Sayan Mountains (Krasnoyarsk District, Russia) sampled from three stations at 15, 25 and 35 km from Krasnoyark. Usnea species with an abnormal morphology dominated on branches in the upper canopy, 15-22 m above ground level, and normal thalli on lower tree branches, 2-5 m above ground. Abnormal thalli at the tree-top level contained higher Al, Fe, Zn, F, Sr and Pb concentrations compared with normal thalli growing below, confirming a dust impact. No such clear trend was observed between sampling stations. Crown canopy architecture, surface microtopography and the balance between the processes of deposition and the movement and loss of particles play a major role in particle interception and in pollutant delivery to Usnea.

Аннотация: The contents of ascorbic acid (AA) and its oxidized form, dehydroascorbic acid (DHA), were assessed as related to the tracheid differentiation in the course of early and late wood development in the Siberianlarch (Larix sibirica Ldb.) trees. The samples of the cambium, cell enlargement zone and mature cells were collected at the successive developmental stages by scraping tissues off layer by layer from trunk segments of the 20-year-old trees according to anatomical and histochemical criteria. While cambium initials were rapidly dividing, the AA contents per dry weight and per cell considerably exceeded the corresponding values characteristic of the late xylem development; such difference corresponded to the higher number of early tracheids per annual ring, as compared to the late tracheids. The AA content decreased as cells enlarged. The radial growth of the early wood tracheids, as compared to the late wood tracheids, was accompanied with a threefold increase in the AA and a decline in the DHA contents. The AA/DHA ratio was in line with the early tracheid enlargement. The maximum AA content was observed at the early stage of the secondary cell wall thickening in the tracheids of early and late xylem preceding lignification. During this stage of early wood development, the DHA content exceeded sixfold the corresponding value in the late xylem; as a result, the initial rates of lignification were different in two tissues. The rate of lignification in a newly developing layer of the early xylem increased gradually and was the highest in the completely differentiated tracheids. In the late xylem, the lignification rate was at its highest at the very beginning and then declined in the course of tracheid maturation. The dissimilar patterns of lignification in the early and late xylem were primarily associated with the DHA content, which increased in the early xylem and decreased in the maturing late xylem. Thus, the AA content and its accessibility to oxidation in the growing and mature xylem cells exhibited the diverse developmental patterns in the early and late xylem: two tissues differed in the tracheid number and radial diameter as well as in the rate of lignification.

Аннотация: The deposition of cellulose, matrix polysaccharides and lignin during secondary cell wall development of early- and latewood in larch (Larix sibirica Ldb.) were studied using biochemical and histochemical methods. Active tissues at successive stages of secondary cell wall development were sampled from larch trunk and characterized by morphological parameters and the content of cellulose, lignin and matrix hemicelluloses, being the structural base for lignification. Matrix polysaccharides were divided by their solubility in 4 % and 24 % KOH and neutral medium. All data were accounted per dry weight and per cell. The amount of biomass (as cell wall cross-section area) deposited before lignification was more in earlywood tracheids than in latewood ones. In contrast. the amount of cellulose at this stage was more in latewood tracheids. The intensity of cellulose synthesis was the highest at the initial stage of lignin deposition in both earlywood and latewood and then declined towards to mature xylem. The intensity of lignin deposition was the highest at the last stage of secondary cell wall development during earlywood formation and from the outset of latewood lignification, dropping towards mature xylem. The contents of A and B hemicellulose fractions linked or not with cellulose, before and after beginning of lignification were different during earlywood and latewood formation. Before lignin deposition, the content of B-4 fraction in both earlywood and latewood was practically equal as well as of B-24, while the amount of A-4 fraction before lignification of early xylem was two times more than that of latewood. This shows different matrix base for the beginning of lignification. All together can be the reason for different physicochemical properties of two types of wood in larch.

Аннотация: Changes in stemwood calcium concentration ([Ca]) for the last 120 years occurred in a common pattern for two sample collections of red spruce (n=33 and 20) from the northeastern United States and for one sample collection of Siberian fir (n=20) from southcentral Siberia, Russia. The [Ca] was measured for wood formed during the periods 1871-90, 1891-1910, 1911-30, 1931-50, 1951-70 and 1971-90. For each core, the relative increase or decrease in [Ca] for adjacent periods of wood formation was recorded. The relative frequency of positive change in [Ca] for each period of wood formation was calculated for the three sample collections. Previous research indicated that under equilibrium conditions, [Ca] in stemwood tended to decrease in more recently formed wood, due to declining numbers of Ca binding sites. Consequently, we expected a low frequency of positive changes in [Ca] in successively formed wood. Consistent with expectation, the relative frequency of positive change from the preceding period to the periods 1891-1910, 1911-30, 1931-50, and 1971-90 were low. Contrary to expectation, the frequency of positive increases in [Ca] more than doubled in 1951-70 compared to 1931-50. The frequency of positive increases in the 1951-70 period relative to the preceding period was 48%, significantly greater than all other periods (P less than or equal to 0.01). The frequencies of positive increases for all other periods were not significantly different from each other (overall mean = 21%, SD = 7). This anomaly in the frequency of positive change in [Ca] in wood formed in 1951-70 relative to wood formed in 1931-50 indicated a perturbation in the ion exchange chemistry of stemwood in two widely separated parts of the northern coniferous forest. This anomaly could be due to external or internal factors. Changes in sap chemistry that affected stemwood chemistry could have been due to changes in the rooting zone. Such changes in rooting zone chemistry could result from the atmospheric deposition of ionic pollutants. Other external factors that could cause the observed anomaly include unusual climatic periods or environmental disturbances such as logging or fire. Internal factors that might produce an anomalously high frequency of positive change of [Ca] include heartwood formation, stemwood infection and a hypersensitive response of the tree against infection.

Аннотация: The impact of long-term seasonal soil freezing, drought, and waterlogging on the rhizosphere of young Scots pine trees (Pinus sylvestris L., age class 1) has been simulated in experiments. The results have shown that cold stress exposure leads to reduction of the rates of linear and radial tree growth and of chlorophyll content in needles, a shift in the peak of starch content, and initiation of free amino acid deposition in the aboveground plant parts. Drought activates utilization of carbohydrate reserves and amino acid accumulation in the root bast, whereas soil waterlogging stimulates deposition of carbohydrates but causes a decrease in the levels of chlorophyll and amino acids in all plant tissues.

Аннотация: The influence of temperature (T) and water potential (psi) on the denitrification potential, C and N mineralization and nitrification were studied in organic and mineral horizons of an acid spruce forest soil. The amount of N2O emitted from organic soil was 10 times larger than from the mineral one. The maximum of N2O emission was in both soils at the highest water potential 0 MPa and at 20 degrees C. CO2 production in the organic soil was 2 times higher than in mineral soil. Net ammonification in organic soil was negative for most of the T-psi variations, while in mineral soil it was positive. Net nitrification in organic soil was negative only at the maximum water potential and temperature (0 MPa, 28 degrees C). The highest rate was between 0 and -0.3 MPa and between 20 and 28 degrees C. In mineral soil NO3- accumulated at all T-psi variations with a maximum at 20 degrees C and -0.3 MPa. We concluded that in organic soil the immobilization of NH4+ is the dominant process in the N-cycling. Nevertheless, decreasing of total N mineralized at 0 MPa and 20-28 degrees C can be explained by denitrification.

Аннотация: To clarify the influence of tree species on N2O emissions, soil chemical properties, initial concentrations of denitrifying enzymes and dynamics of N2O emissions were studied in the laboratory under standardized conditions in soil samples from artificially afforested spots with spruce, birch, pine, aspen, larch, cedar and under grass as control. 26 years of tree development caused changes not only in soil chemistry but also in persistence and dynamics of denitrifying enzymes. Total amount of N2O release correlated more with the initial status of N2O-reductase than with N2O-producing enzymes. C:N ratio was the main chemical factor explaining variation of N2O emission between species. At equal level of atmospheric N-deposition, N2O release will increase in the order: grassland < larch < pine < spruce < cedar < aspen < birch. These data may be useful to predict N2O losses from forest ecosystems in Siberia with different dominant tree species.

Аннотация: As are other parts of the earth, arctic and subarctic territories are influenced by global, regional, and local air pollution. In Europe, the greatest load of airborne contaminants is observed in terrestrial ecosystems of the Kola Peninsula; in Asia, the greatest load is found in ecosystems of the Taimyr Peninsula, where large copper-nickel smelters are functioning. The studies described here for these regions encompassed local and regional deposition of pollutants (mainly sulfates and trace metals); changes in the composition, structure, productivity, and status of forest vegetation; morphological reactions of plant species and their regenerative activity; reforestation processes; successions; element composition of plants and soils; and biological activity of soils. The key findings of long-term studies are as follows. First, the symptoms of plant damage by air and soil pollutants in arctic and temperate zones are the same. Second, plants weakened by natural stresses have lower thresholds of sensitivity to airborn pollutants. Third, rapid destruction of northern plant communities by pollutants is often connected with a wide distribution of sensitive species (e.g., lichens) and previously weakened plants. Fourth, the specific structure of far northern forest and tundra ecosystems (in particular, open canopy and/or thin photosynthetic layer) and the severe climate produce some peculiarities in plant damage, namely (1) a large difference in the rate and intensity of damage to upper and lower parts of plants if the green parts are above or under snow in the winter, (2) simultaneous damage of different parts of stands that are above snow cover, and (3) an increase in the krummholz effect (stunted, low-lying branches) for evergreen coniferous trees. These findings were obtained for conditions of evident airborne contamination. The impact of low level regional pollutants on arctic and subartic vegetation is not sufficiently understood.

Аннотация: Lignin deposition at consecutive secondary wall thickening stages of early and late xylem cells during annual ring wood formation in Scots pine (Pinus sylvestris L.) stems was studied. Lignin patterns, isolated by thioglycolic acid method, consisted of alcohol-soluble (LTGA-I) and alkali-soluble (LTGA-II) fractions. The sum of two fractions, being the total lignin content, gradually increased in the course of lignification. However, the increments of lignin amount at each development stage of early and late tracheids were different. The intensity of lignin deposition increased in the course of earlywood tracheid maturation and decreased toward the end of latewood cell differentiation. The deposition of two lignin fractions in each layer of forming wood also occurred oppositely. The increment of LTGA-I descended, whereas that of LTGA-II increased from the beginning to the end of early xylem lignification. In contrast, LTGA-I increment dropped, whereas LTGA-II rose during late xylem lignification. Gel permeation chromatography showed that the lignins, formed at the beginning of lignification, were more homogeneous and had higher molecular weight compared with the lignins at the end of cell differentiation. Besides, the content of cellulose, estimated as the residue after lignin isolation, and of cell wall substances, presented as cell wall cross-section areas, at consecutive maturation stages of early and late xylem cells have been found to be different. The data show that lignin deposition occurred in different conditions and with opposite dynamics during early and late xylem formation. © 2014 Springer-Verlag Berlin Heidelberg.

Аннотация: Estimations of tree annual biomass increments are used by a variety of studies related to forest productivity or carbon fluxes. Biomass increment estimations can be easily obtained from diameter surveys or historical diameter reconstructions based on tree rings' records. However, the biomass models rely on the assumption that wood density is constant. Converting volume increment into biomass also requires assumptions about the wood density. Wood density has been largely reported to vary both in time and between trees. In Norway spruce, wood density is known to increase with decreasing ring width. This could lead to underestimating the biomass or carbon deposition in bad years. The variations between trees of wood density have never been discussed but could also contribute to deviations. A modelling approach could attenuate these effects but will also generate errors. Here a model of wood density variations in Norway spruce, and an allometric model of volume growth were developed. We accounted for variations in wood density both between years and between trees, based on specific measurements. We compared the effects of neglecting each variation source on the estimations of annual biomass increment. We also assessed the errors of the biomass increment predictions at tree level, and of the annual productivity at plot level. Our results showed a partial compensation of the decrease in ring width in bad years by the increase in wood density. The underestimation of the biomass increment in those years reached 15 %. The errors related to the use of an allometric model of volume growth were modest, around ±15 %. The errors related to variations in wood density were much larger, the biggest component being the inter-tree variability. The errors in plot-level annual biomass productivity reached up to 40 %, with a full account of all the error sources. © Author(s) 2015.

Аннотация: Steep mountain terrain, fractured geological environments, and intense precipitation events are primary factors that contribute to frequent landslides in mountainous regions. Landslides exert an immense impact on forest ecosystems and substantially change soil properties; understanding these changes is crucial to facilitating subsequent forest revegetation and management. In this study, the effects of landslide on soil physicochemical properties were investigated in a moist montane forest ecosystem in Xitou, Central Taiwan. We established a dataset comprised historical soil survey data obtained in 1976 and data from soil samples taken in 2012 at the same locations to compare differences in soil properties after landslide deposition, and also conducted soil sampling along a landslide/nonlandslide affected sequence to determine how the degree of landslide deposition affected soil physicochemical properties. The results indicated that rock fragment content, soil pH value, bulk density, inorganic carbon, and base saturation increased following landslide deposition and that severe landslide deposition caused more substantial increases. By contrast, the thicknesses of the O and A horizons, soil organic carbon, total nitrogen, and cation-exchange capacity significantly decreased following landslides; these decreases were more substantial with increasing degree of landslide deposition. Exchangeable potassium, calcium, magnesium, and available phosphorus content, however, were unaffected by landslide deposition. The results demonstrated that soil physicochemical properties were significantly altered after landslide deposition; these resultant changes, particularly in regard to high soil pH value, poor structure, and low soil organic carbon and total nitrogen, are expected to influence functions in forest ecosystems. © 2015 Elsevier B.V.

Аннотация: This work focuses on the behavior of the stable Mg and Si isotope compositions of the largest Arctic river, the Yenisey River and 28 of its major and minor tributaries during the spring flood period. Samples were collected along a 1500 km latitudinal profile covering a wide range of permafrost, lithology, and vegetation. Despite significant contrasts in the main physico-geographical, climate, and lithological parameters of the watersheds, the isotope composition of both dissolved Mg and Si was found to be only weakly influenced by the degree of the permafrost coverage, type of vegetation (forest vs. tundra), and lithology (granites, basalts, carbonates or terrigenous rocks). This observation is generally consistent with the lack of chemical uptake of Mg and Si by soil mineral formation and vegetation during the early spring. The radiogenic Sr isotope composition of the Yenisey and its tributaries varied within a narrow range (0.708 ? 87Sr/86Sr ? 0.711) reflecting the dominance of Phanerozoic rock weathering and/or atmospheric deposition on these compositions. The Mg and Si isotopic compositions of riverine samples reflect two main processes with distinct isotopic signatures. First, isotopically heavier Mg (?26Mg = ?1.0 ± 0.2‰) and isotopically lighter Si (?30Si = 1.0 ± 0.25‰) are added to the waters by river suspended matter dissolution and leaching from vegetation biomass/topsoil litter. Second, isotopically lighter Mg (?26Mg = ?1.5 to ?1.75‰) and isotopically heavier Si (?30Si = 1.75–2.0‰) are delivered to the Yenisey's tributaries from deep underground water feeding the rivers via taliks. This lighter Mg and heavier Si isotopic composition is interpreted to originate from Precambrian dolomite dissolution and aluminosilicate dissolution coupled with authigenic mineral precipitation, respectively, in deep underground water reservoirs. Taking account of the isotopic composition evolution over the course of the year established earlier on mono-lithological watersheds of the Yenisey basin, the average annual isotopic signatures of the Yenisey river arriving to the Arctic Ocean are estimated to be ?26Mg = ?1.58 ± 0.30‰ and ?30Si = +1.60 ± 0.25‰. As the Yenisey is the largest river feeding the Arctic Ocean and as it samples a large variety of environments and lithologies, these values may be reasonable estimates for the average Mg and Si isotopic composition of the dissolved riverine flux to the Arctic Ocean. © 2016 Elsevier Ltd

Аннотация: The eruption of Samalas in Indonesia in 1257 ranks among the largest sulfur-rich eruptions of the Common Era with sulfur deposition in ice cores reaching twice the volume of the Tambora eruption in 1815. Sedimentological analyses of deposits confirm the exceptional size of the event, which had both an eruption magnitude and a volcanic explosivity index of 7. During the Samalas eruption, more than 40 km(3) of dense magma was expelled and the eruption column is estimated to have reached altitudes of 43 km. However, the climatic response to the Samalas event is debated since climate model simulations generally predict a stronger and more prolonged surface air cooling of Northern Hemisphere summers than inferred from tree-ring-based temperature reconstructions. Here, we draw on historical archives, ice-core data and tree-ring records to reconstruct the spatial and temporal climate response to the Samalas eruption. We find that 1258 and 1259 experienced some of the coldest Northern Hemisphere summers of the past millennium. However, cooling across the Northern Hemisphere was spatially heterogeneous. Western Europe, Siberia and Japan experienced strong cooling, coinciding with warmer-than-average conditions over Alaska and northern Canada. We suggest that in North America, volcanic radiative forcing was modulated by a positive phase of the El Nino-Southern Oscillation. Contemporary records attest to severe famines in England and Japan, but these began prior to the eruption. We conclude that the Samalas eruption aggravated existing crises, but did not trigger the famines.

Аннотация: Arctic driftwood may represent a cross-disciplinary proxy archive at the interface of marine and terrestrial environments, which will likely gain in importance under future global climate change. Circumpolar network analyses that systematically consider species-specific boreal origin areas, transport routes and deposition characteristics of Arctic driftwood, are, however, missing. Here, we present tree-ring width (TRW) measurements of 2412 pine, larch and spruce driftwood samples from Greenland, Iceland, Svalbard, the Faroe Islands, and the Lena Delta in northeastern Siberia. Representing the largest Arctic driftwood TRW compilation, these data are compared against 495 TRW reference chronologies from the boreal forests of Eurasia and North America. The southern Yenisei region is the main source for recent pine driftwood at all Arctic sampling sites, whereas spruce mainly originates in western Russia and central Siberia, as well as in northern North America. Larch driftwood is, for the first time, dendro-provenanced to central and eastern Siberia. A new larch driftwood chronology extends the middle Lena River reference chronology back to 1203 CE. Annually resolved radiocarbon measurements further date six larch driftwood chronologies between 1294 and 2013 CE. Although being highly replicated, our study emphasizes the importance of interdisciplinary research efforts including radiocarbon dating, isotopic tracing and aDNA processing for improving Arctic driftwood provenancing in space and time. If successful, Arctic driftwood studies will contribute to the reconstruction of past boreal summer temperature variations and ocean current dynamics, as well as changes in sea ice extent and relative sea level over the last centuries to millennia. © 2017 Elsevier Ltd

Аннотация: This study aimed to better understand the stabilisation of rice rhizodeposition in paddy soil under the interactive effects of different N fertilisation and water regimes. We continuously labelled rice ('Zhongzao 39') with (CO2)-C-13 under a combination of different water regimes (alternating flooding-drying vs. continuous flooding) and N addition (250 mg N kg(-1) urea vs. no addition) and then followed C-13 incorporation into plant parts as well as soil fractions. N addition increased rice shoot biomass, rhizodeposition, and formation of C-13 (new plant-derived C) in the rhizosphere soils under both water regimes. By day 22, the interaction of alternating flooding-drying and N fertilisation significantly increased shoot and root C-13 allocations by 17 and 22%, respectively, over the continuous flooding condition. The interaction effect also led to a 46% higher C-13 allocation to the rhizosphere soil. Alone, alternating water management increased C-13 deposition by 43%. In contrast, N addition increased C-13 deposition in rhizosphere soil macroaggregates under both water regimes, but did not foster macroaggregation itself. N treatment also increased C-13 deposition and percentage in microaggregates and in the silt and clay-size fractions of the rhizosphere soil, a pattern that was higher under the alternating condition. Overall, our data indicated that combined N application and a flooding-drying treatment stabilised rhizodeposited C in soil more effectively than other tested conditions. Thus, they are desirable practices for improving rice cropping, capable of reducing cost, increasing water use efficiency, and raising C sequestration.

Аннотация: Lignification of earlywood and latewood during annual ring formation in Scots pine stem in the season occurs with opposite dynamics. The subject of this study was to examine the structure of lignin deposited at successive stages of secondary cell wall maturation of these two wood types. Lignin specimens derived from developing cells by the thioglycolic acid were analyzed by the methods of alkaline oxidation, alkaline and acid hydrolysis and IR Fourier spectroscopy. The composition of lignin structural subunits was found to change at each stage of lignification in dependence of the forming wood type. The molar ratio of p-hydroxyphenyl, guaiacyl and syringyl subunits in polymer was modified in earlywood and latewood oppositely. In the course of earlywood cell maturation, syringyl subunits in lignin increased in parallel with p-hydroxyphenyl units. During latewood lignification, syringyl and p-hydroxyphenyl subunits in lignin structure decreased, whereas guaiacyl subunits increased as secondary cell wall maturation. In lignin isolated from both wood types, the ether-bound carbohydrates were more than by an order of magnitude of ester-bound carbohydrates. In early xylem, the content of ether-bound carbohydrates practically did not change during lignin deposition, whereas carbohydrates with ester linkages gradually decreased toward mature xylem. Lignification in latewood was accompanied by the decline of both ester-linked and ether-linked carbohydrates with a sharp increase in the latter in mature xylem. Hemicelluloses, included in such bonds, contained mainly the residues of xylose and arabinose. The composition and the content of hydroxycinnamic acids, taking part in these linkages, also changed in dependence of lignification steps and wood type. The data received are in agreement with the alterations in absorption IR spectra of lignins isolated from the cells at the beginning of lignification and mature xylem. The reasons for the differences in the lignin structure during earlywood and latewood development are discussed. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Аннотация: Рассмотрен вклад академика А.С. Исаева в развитие лесной науки. Наиболее существенные достижения находятся в русле четырех направлений: лесная энтомология, аэрокосмический мониторинг лесов, цикл углерода в лесах, биоразнообразие лесов. В области лесной энтомологии А.С. Исаевым с соавторами предложена феноменологическая теория динамики численности лесных насекомых. Эта теория объясняет все возможные режимы динамики численности, не требует построения конкретных математических моделей динамики численности популяции, указывает, какие ключевые характеристики динамики необходимо оценить для определения возможности и рисков вспышек массового размножения. А.С. Исаев одним из первых понял огромные возможности аэрокосмического мониторинга лесов. Им была предложена концепция многоуровневой системы дистанционного мониторинга лесов, способная решать разнообразные научные и практические задачи. Большое внимание А.С. Исаев уделил проблеме углеродного цикла лесов в связи с проблемой изменения климата. В его публикациях даны первые оценки запасов и депонирования углерода лесами России, полученные на основе лесоучетной информации. Методы расчета углеродных параметров, предложенные в этих работах, были позже закреплены в руководствах МГЭИК по составлению национальных кадастров парниковых газов. Методология мониторинга биоразнообразия лесов, разработанная под руководством академика А.С. Исаева, базируется на концептуальном подходе, учитывающем пространственно-временную динамику лесообразовательного процесса, с применением методов математического моделирования, позволяющего интерпретировать процессы и прогнозировать изменения. Данная технология обеспечивает выявление тенденций изменения породно-возрастной структуры лесов и позволяет осуществлять прогнозное моделирование их естественной и антропогенной динамики при различных режимах охраны, использования и воспроизводства.
The contribution of academician A.S. Isaev to advancement of forest science is considered. The most significant achievements were in the spheres of forest entomology, aerospace monitoring of forests, forest carbon cycle and forest biodiversity. A.S. Isaev and coauthors have put forward phenomenological theory of population dynamics of forest insects. It encompasses all possible types of population dynamics, it does not demand the specific mathematical models of population dynamics and points at the key features, controlling the probability and risks of the outbreaks. A.S. Isaev was among the pioneers of aerospace monitoring of forests. He proposed the concept of multi-layered system of the remote monitoring of forests to address various research and applied demands. A.S. Isaev have payed high attention to forest carbon cycle associated to the challenges of climate change. He have published the first estimates of the forest carbon storage and deposition in Russia based on the forest inventory data. The methods of accounting of carbon were later included in technical guidance of the IPCC on the National Reporting on Inventory of Greenhouse Gases. The technology of monitoring of biodiversity of forest developed under the supervision of academician A.S. Isaev takes into account spatiotemporal dynamics of forest forming processes, applies mathematical modeling of processes and forecasts changes. It allows deciphering the trends in species and age structure of forests and model predictions of natural and human-induced dynamics under different protection, exploitation and regeneration.
