Аннотация: A model of the population dynamics of insects has been developed, which takes into account the food consumption by insects and the reaction of food plants to the damage. Equations have been derived that describe the relationship between the coefficient of insect reproduction, the weight of females, the energetic effectiveness of the food consumption by insects, and the reaction of food plants. The scenarios of population outbreaks have been analyzed as a function of the weight of females in the stable state. The results of modeling have been compared with the data of natural observations.

Аннотация: During 1993-1996, in central Siberia, a silkmoth (Dendrolimus superans sibiricus Tschetw.) infestation damaged approximately 700 000 ha of fir, Siberian pine and spruce stands. Temporal (1995-1997) Advanced Very High Resolution Radiometer (AVHRR) images were used for pest outbreak monitoring of this event. Damaged stands were detected, with heavy (50-75% dead and dying trees) plus very heavy (75%) levels of damage classified. Summer and winter images were used for delineation of the northern border of the region of pest outbreaks. The Siberian taiga insects were classified with respect to their harmfulness to forests, based on the frequency Of Outbreaks, the size of the damaged territory, and the available food sources based on forest type.

Аннотация: We analyzed tree rings in wood samples collected from some of the few surviving trees found close to the epicenter (within 4-5 km) of the Tunguska event that occurred on the last day of June 1908. Tree-ring growth shows a depression starting in the year after the event and continuing during a 4-5-year period. The most remarkable traces of the event were found in the rings' anatomical structure: (1) formation of "light" rings and a reduction of maximum density in 1908; (2) non-thickened tracheids (the cells that make up most of the wood volume) in the transition and latewood zones (the middle and last-formed parts of the ring, respectively); and (3) deformed tracheids, which are located on the 1908 annual ring outer boundary. In the majority of samples, normal earlywood and latewood tracheids were formed in all annual rings after 1908. The observed anomalies in wood anatomy suggest two main impacts of the Tunguska event on surviving trees-M defoliation and (2) direct mechanical stress on active xylem tissue. The mechanical stress needed to fell trees is less than the stress needed to cause the deformation of differentiating tracheids observed in trees close to the epicenter. In order to resolve this apparent contradiction, work is suggested on possible topographic modification of the overpressure experienced by these trees, as is an experimental test of the effects of such stresses on precisely analogous growing trees.

Аннотация: Experimental data are analyzed that concern the effect of zoogenic debris on the properties of soddy deep podzolic soils and raw-humus brown soils characteristic of southern taiga forests in the Yenisei region of Siberia. It is shown that the influence of excrements of Siberian moth larvae on the soil microflora lasts for two or, at most, three growing seasons. Zoogenic plant debris failing on the ground surface during tree stand defoliation is a short-acting but powerful stimulant of biological activity in the litter; hence, it has a considerable effect on soil properties. This effect is enhanced by changes in ecological conditions that occur upon defoliation. The influence of the cenotic factor on biogenic soil properties is manifested more strongly in the organogenic horizons. The communities of microorganisms involved in the nitrogen and carbon cycles are dominated by prototrophic forms in the normal fir forest and by pedotrophic forms in the forest defoliated by pests.

Аннотация: As part of a Siberian mapping project supported by the National Aeronautics and Space Administration (NASA), this study evaluated the capabilities of radars flown on the European Remote Sensing Satellite (ERS), Japanese Earth Resources Satellite (JERS), and Radarsat spacecraft and an optical sensor enhanced thematic mapper plus (ETM+) on-board Landsat-7 to detect fire scars, logging, and insect damage in the boreal forest. Using images from each sensor individually and combined, an assessment of the utility of using these sensors was developed. Transformed divergence analysis revealed that Landsat ETM+ images were the single best data type for this purpose. However, the combined use of the three radar and optical sensors did improve the results of discriminating these disturbances.

Аннотация: Landsat data were used to examine the effect of large-scale insect outbreaks in the forests of southern Siberia. Two insect outbreaks were studied: Ket-Chulym, similar to1.5 million hectares of forest damaged between 1954 and 1957; and Priangar'e, similar to0.5-0.7 million hectares of forest damaged between 1994 and 1996. Landsat scenes from 1980 to 2000 were analyzed. The optimal Landsat channels combination for detecting damage classes were bands 2 (0.525-0.605 mum), 4 (0.750-0.900 mum), 5 (1.55-1.75 mum), and 6 (10.40-12.50 mum). The damage to the forests caused an increase inradiometric temperature (20.20 +/- 0.04degreesC for damaged forests versus 19.47 +/- 0.02degreesC for healthy forests). The following pattern of forest succession was observed in the outbreak areas: dead stands with dense grass and shrub communities, burn scars, grass and shrub formations, open woodlands, closed young and middle-age birch stands, mature birch stands, and mixed conifer-deciduous stands. Forest regeneration goes through long-term species-change successions, and the rate depends on the size of the outbreak area. On-ground mapping after the outbreak and later Landsat analysis showed that even 45 years after the Ket-Chulym outbreak the area of forests did not increase. In the Priangar'e area approximately 45% of damaged forests have recovered.

Аннотация: In the southern-taiga low grass-green moss fir forest completely defoliated by the Siberian moth, the rate of soil respiration in the third year after the pest population outbreak was 1.5 times higher than in an undisturbed tree stand. This was explained by a significant increase in the abundance and activity of soil microorganisms in the pest-defoliated forest, which occurred due to the qualitative changes in the litter composition and the increased temperature and moisture in the upper soil layers. The rate of carbon emission from the soil in the defoliated forest was 41.7 kg/ha per day, compared to 28.3 kg/ha per day in the undisturbed fir forest.

Аннотация: The state of microbial cenoses in the soils of forest ecosystems damaged by fires of different strengths and gypsy moth outbreaks (Central Siberia) was assessed by the intensity of the basal respiration, the content of carbon of the microbial biomass, and the microbial metabolic quotient. The degree of the disturbance of the microbial cenoses in the soils under pine forests after fires was higher than that in the soils under the forests defoliated by gypsy moths. The greatest changes of the microbial complexes were recorded after the fires of high and medium intensity. In the litters, the content of the microbial biomass, the intensity of basal respiration, and the microbial metabolic quotient value were restored on the fifth year after the fires, whereas in the upper (0-10 cm) soil layer, these parameters still differed from those in the control variant, especially after the highly intense fires. After the weak fires, the ecophysiological state of the microbial complexes was restored within two-three years.

Аннотация: The spatial pattern of Siberian silkmoth outbreak in south Siberian mountains was analysed based on SPOT VEGETATION data. A digital elevation model (DEM) was also used to relate outbreak area dynamics with topographic elements (elevation, azimuth and slope steepness). To avoid bias of spatial pattern data, areas with a given damage category and with given azimuth, slope steepness and elevation were referenced to the areas with similar parameters within the entire study area. The outbreak began between the elevations of similar to 430-480 m and on south-west slopes with steepness 5 degrees; these conditions appear to be the most favourable pest habitat. As the pest searched for food it moved up and down slope, resulting in an elevation distribution split within a range of similar to 390-540 m and slope steepness up to 15 degrees. In the final phase the azimuth distribution of damaged stands became even, showing that pests at this phase settle in non-optimal habitat. The final outbreak area was similar to 20 000 ha, which is in good agreement with on-ground data. The correlation between the initial phase of infestation and topographic features can be used to prioritize pest monitoring. Data obtained show that the SPOT VEGETATION sensor is applicable for monitoring taiga landscapes vulnerable to Siberian silkmoth outbreaks.

Аннотация: Effect of defoliation on resistance response of Siberian fir, Abies sibirica Ledeb., to fungal inoculation was investigated within three even-aged fir stands damaged by Siberian moth, Dendrolimus superans sibiricus Tschetw., and located in the Krasnoyarsk Territory (Central Siberia). Histological changes in tissues, accompanying the resistance response were examined in 30 fir trees (90-130 years old) of different defoliation degree (50, 75, 100 %) six weeks after single inoculation with Leptographium sp, vectored by Monochamus urussovi Fisch. (Coleoptera: Cerambycidae). It was recorded that the rate and intensity of defence response of phloem and xylem tissues to inoculation as well as percent of trees infested by the insect-vector differed significantly in dependence of defoliation degree. Trees of 50 percent defoliation significantly differed from trees of more severe defoliation in all parameters of defence response and percentage of colonisation by the beetle. The trees defoliated to 75 and 100% did not differ significantly in defence response activity and the number of the trees attacked by M. urussovi Strong difference in resistance to inoculation and colonisation by the beetle was recorded between trees defoliated in the current year and in the previous year. All infested by M, urussovi trees were characterised by the epidemic level of frequency of blue-stain fungi associated with this insect. The tendency was recorded to a decreased frequency of the pathogenic Ophiostoma sp. and a more frequent occurrence of the saprophyte O. curvicollis in trees defoliated in previous year which lost ability to defend against wounding and fungal infection.

Аннотация: The Siberian moth, Dendrolimus sibiricus, Tschtv. is the most harmful defoliator of coniferous forests in North Asia. The pest has already spread over the Urals and continues moving westwards. Recently, it has been recommended for quarantine in member countries by European and Mediterranean Plant Protection Organization (EPPO). The performances of the pest on coniferous species planted in Europe were assessed on a range of potted trees corresponding to the spectrum of economically important conifers in the EU: European larch Larix decidua, Norway spruce Picea abies, Scots pine Pinus sylvestris, European black pine Pinus nigra, and the North American species: Douglas fir Pseudotsuga menziesii and grand fir Abies grandis. Larvae showed a potential to survive and complete the development on all these host tree species. Favorable hosts were grand fir, European larch, and Douglas fir that allowed higher survival, better larval development, and as a result, yielded heavier pupae and adult moths with higher longevity. Black pine was a poor host but, however, could still support larval and pupal development. Norway spruce and Scots pine had an intermediate behavior. If accidentally introduced to Europe, the Siberian moth may become especially damaging in forest stands predominated by European larch and by the North American firs. Norway spruce and especially the two-needle pines will be less prone to intensive defoliation by this species. The fact that the pest may damage the range of economically important coniferous species should be taken into account in the pest risk assessment for Europe and also for North America where the Siberian moth occurrence is considered likely.

Аннотация: The effect of spring defoliation on different aspects of growth and metabolism of 10-year Scots pine trees (Pinus silvestris L.) in natural stands of the Krasnoyarsk forest-steppe region have been studied. These aspects include the structure of annual xylem and phloem increments, the content of starch and photosynthetic pigments in phloem, and the activity of antioxidative enzymes in xylem and phloem. It is shown that defoliation reduces shoot elongation, as well as the length and mass of needles and width of annual rings in xylem and phloem. It also stimulates late wood formation, an increase in total contents of photosynthetic pigments in the needles of newly formed shoots, and a reduction of starch contents in stem phloem. A significant increase of peroxidase activity in the xylem of defoliated trees can be a sign of oxidative stress. Defoliation has an evident negative effect on the formation of the annual rings of xylem, but does not have that strong an impact on phloem genesis. In general, during defoliation, the reserve function of the trees prevails over the growth function.

Аннотация: В очаге лиственничной чехликовой моли Coleophora sibiricella Falkovitsh в чистом лиственничнике исследован защитный ответ флоэмы ствола лиственницы сибирской Larix sibirica Ledeb. на поранение или инокуляцию ствола грибным индуктором. В качестве грибного инокулята использовали мицелий офиостомового гриба Ceratocystis laricicola Redfern & Minter, его экстракт и белковую фракцию, полученную из экстракта. Содержание лигнина, крахмала, конденсированных дубильных веществ (проантоцианидинов) во флоэме определено в начале опыта (0 сут), через 7 и 14 сут. С помощью анализа ANOVA показано, что параметры ответа флоэмы не зависели от формы грибного инокулята (р ≥ 0.918), но зависели от других факторов (р ≤ 0.005) – повреждения кроны молью, времени от начала опыта, наличия инокулята в ране

Mycelium of the ophiostomoid fungus Ceratocystis laricicola Redfern & Minter, its extractive and protein fraction obtained from the extractive were used as a fungal inductor. The content of lignin, starch, condensed tannins (proanthocyanidins) in the phloem was determined at the beginning of the experiment (0 days), after 7 and 14 days. Using ANOVA analysis, it was shown that the response parameters of the phloem did not depend on the shape of the fungal inoculum (p ≥ 0.918), but depended on other factors (p ≤ 0.005) - damage to the crown by the moth, time from the start of the experiment, and the presence of the inoculum in the wound

Аннотация: Реконструирована история массовых размножений сибирского шелкопряда ( Dendrolimus sibiricus Tschetverikov, 1908) в лиственничниках лесостепи восточных предгорий Кузнецкого Алатау (запад Чулымо-Енисейской котловины, юг Восточной Сибири, Республика Хакасия). Вспышки массового размножения этого вида неоднократно охватывали леса от Урала до Дальнего Востока на площади более 1 млн га. Однако имеется недостаток продолжительных рядов наблюдений за изменениями численности популяций сибирского шелкопряда. Данные об истории нанесенной им дефолиации позволят хотя бы частично восполнить этот пробел. Для реконструкции нами был изучен радиальный прирост в шести лиственничных древостоях, в прошлом подвергавшихся массовым размножениям сибирского шелкопряда. С помощью алгоритма Outbreak в рядах радиального прироста обнаружены специфические признаки (резкие, глубокие и продолжительные спады прироста), указывающие на дефолиацию в прошлом. Всего в 1740-2017 гг. был обнаружен 31 такой период. Исследование частотных характеристик хронологии дефолиации показало, что после завершения Малого Ледникового периода интервал между дефолиациями постепенно снижался с 10-11 в конце XIX в. до 7 лет в 1930-х годах. С 1940-х годов этот интервал уменьшился до 4-6 лет, что мы связываем с антропогенным воздействием (массированные рубки и, видимо, участившиеся низовые пожары). Следствием этого стали фрагментация древостоев и периодическое уничтожение пожарами зимующих энтомофагов. В результате частота появления очагов сибирского шелкопряда в районе исследований возросла или за счет выхода его из-под контроля энтомофагов, или в результате образования системы существующих в разное время миграционных очагов в фрагментированных древостоях
The outbreaks history of the Siberian moth ( Dendrolimus sibiricus Tschetveraikov, 1908) in larch forests of the forest-steppe at the eastern foothills of the Kuznetsk Alatau mountains (West of the Chulym-Yenisei basin, South of Eastern Siberia, Republic of Khakassia) is reconstructed. Outbreaks of this species have repeatedly covered forests from the Urals to the Far East on an area of more than 1 million hectares. However, there is a lack of long series of observations of changes in the size of the Siberian moth populations. Data on the history of the defoliations caused by it will at least partially fill this gap. For reconstruction, we studied the radial growth in six larch stands, which in the past were subjected to intensive defoliation by the Siberian moth. Using the OUTBREAK algorithm, specific features (abrupt, deep, and prolonged declines in growth) were found in the series of radial growth, indicating defoliation in the past. In total 31 such periods were found in 1740-2017. A study of the frequency characteristics of the chronology of defoliation showed that after the end of the Little Ice Age, the interval between defoliations gradually decreased from 10-11 years at the end of the 19th century to 7 years in the 1930s. Since the 1940s, this interval has decreased to 4-6 years, which we attribute to anthropogenic impact (massive logging and, apparently, more frequent ground fires). The consequence of this was the fragmentation of forest stands and the periodic eliminations of overwintering entomophages by fires. As a result, the frequency of occurrence of the Siberian moth foci in the study area increased either due to its escape from the control of entomophages, or because of the formation of a system of migration foci that existed at different times in fragmented forest stands

Аннотация: Siberian silkmoth (SSM,Dendrolimus sibiricusTschetv.) is the most important defoliator of Siberian pine (Pinus sibiricaDu Tour) and fir (Abies sibiricaLedeb.) stands. Warming-induced SSM outbreaks are one of the major driving factors of successions within the taiga zone. It is suggested that climate change impacted the SSM range and life cycle. We analyzed the migration of alpine and northerly SSM outbreak boundaries in Siberia and the impact of the climate variables and topography on the outbreak dynamics. We used time-series scenes (multispectral data, and vegetation indexes EVI and NDII) in combination with field studies, climate variables, and GIS techniques. We found that SSM outbreaks in the area of alpine boundary shifted about 370 m uphill since the mid of 1950. The outbreak onset was promoted by increased dryness and active temperatures and decreased root zone moisture content in the spring-early summer period. The terrain topography strongly affected SSM outbreak onset and dynamics. Initially, the outbreak was located at the middle elevations on the gentle concave southeastern slopes, which are the favorable insect habitats between outbreaks. Then the outbreak expanded uphill and downhill, to steeper slopes, and both concave and convex terrains. Alongside with elevation range expansion, SSM surpassed its northern historical outbreak boundary: the potential outbreaks' boundary moved about 300 km northward. Climate warming contributes to SSM migration into former outbreak free conifer stands located in highlands and at northern latitudes.

Аннотация: The pine looper Bupalus piniaria is one of the most widespread phyllophagous insect species across Northern Eurasia, defoliating Scots pine forests over vast territories. Since there are not enough long-term documented observations on a series of outbreaks, there is a need for methods allowing them to be reconstructed to study their dynamics patterns. Previously, dendrochronological methods were successfully used to solve such issues. However, the most common approach is not applicable for the Western Siberian forest-steppe since it requires comparison with a non-damaged tree species close to pine in terms of longevity and resistance to rot. In the pine forests of the steppe and forest-steppe zones of Western Siberia, there are no species that are not damaged by the pine looper that meets these requirements. Methods allowing not using control species are also not free from disadvantages (e.g., weak specificity). Therefore, we have developed a new method based on the analysis, not of the tree-ring width but the early-and latewood width to reconstruct past defoliation events. The past defoliation by the pine looper is indicated by the presence of a negative pointer year for latewood, followed by a negative pointer year for earlywood in a subsequent year among the majority of individuals. Linear modeling showed a difference between the climate impact on radial growth and the defoliation one. The obtained reconstruction was compared with the results of other methods (mowing window, OUTBREAK, independent component analysis), literature, and Forest Service data. The developed new method (pointer year method; PYM) showed high efficiency confirmed by results of the tree-ring series analysis (11 revealed outbreaks in the past). Compared with other reconstruction techniques under the given conditions (a favorable combination of heat and humidity; probably low-intense and short defoliation), the proposed method provided more precise results than those proposed earlier. Due to high accuracy, the PYM can be useful for detecting late-summer and autumn past defoliations of tree species with clear difference between early-and latewood even though the damage was weak. © 2021 by the authors.

Аннотация: Abstract: One of the possible consequences of climate change is a change in the demographic dynamics of phyllophagous insects. For a retrospective analysis of this dynamics, tree rings are used, especially in regions with limited documentary data. Due to the complex nature of the factors determining tree growth, in order to more clearly identify pest-induced defoliation in tree-ring chronologies one suppress the climatic signal expressed directly or indirectly (through chronologies of non-host tree species). However, in South Siberia, the choice of non-host species is hampered by the wide distribution of polyphages, like the gypsy moth (Lymantria dispar Linnaeus) and the Siberian silk moth (Dendrolimus sibiricus Tsch.). Therefore, the analysis of pest outbreaks in larch forests of the Republic of Tuva low mountains was started by removing the climatic response based on instrumental data, identifying depressions in the residual time-series of individual tree radial growth at several sites, and comparing them with available actual data on forest damage by phyllofages. Dendroclimatic analysis showed that the model including the precipitation-to-maximum-temperature ratio for June-September of the previous season and June of the current year, i.e. the degree of aridity during the previous and current growing season, describes 43.7% of the regional variation in the growth of Siberian larch (Larix sibirica Ledeb.). After removal of this component, several periods of larch growth depression were revealed during confirmed outbreaks of the Siberian silk moth, gypsy moth, and larch tortrix (Zeiraphera diniana Gn.). The use of documented data over 1998–2016 allowed to clarify the threshold values of the portion of affected trees for intensities of the growth depression ranging 1–1.5 standard deviations, providing the required reliability of the outbreak reconstruction. The dependence of the spatio-temporal patterns of growth depression on the pest species was revealed, reflecting their migration in the affected area. It has been shown that growth depressions may be delayed compared with the actual damage by pests due to the long recovery after recurrent defoliation. © 2021, Pleiades Publishing, Ltd.

Аннотация: Simple Summary The pine looper damages Scots pine forests over vast areas. However, the study of its population fluctuations is hampered by the lack of long-term observation series. The dendrochronological reconstruction is often used to study the history of its outbreaks. In some cases, such reconstructions require methods that work without comparison with other tree species. We have proposed such a technique based on the analysis of the early- and latewood growth. The technique makes it possible to separate the effect of defoliation on tree rings from weather influence. Besides, it is more sensitive than previously developed methods when reconstructing outbreaks of the pine looper. The history of outbreaks reconstructed by the technique for the West Siberian Plain's forest-steppe includes 11 defoliation events from 1914 to 2017. The results obtained using the developed method are useful to better understand the patterns of population dynamics of the pine looper and other phyllophagous pests. The pine looper Bupalus piniaria is one of the most widespread phyllophagous insect species across Northern Eurasia, defoliating Scots pine forests over vast territories. Since there are not enough long-term documented observations on a series of outbreaks, there is a need for methods allowing them to be reconstructed to study their dynamics patterns.
