Аннотация: Problem of wildfires has not been resolved anywhere in the world. Mere increase of technical power does not lead to desirable results. Forests of developed countries burn as actively as those in Africa or in Russia. The main reasons of wildfire problem are as follows: (1) Constant wandering of dry seasons over the planet causing outbreaks of wildfires. (2) Unpredicted self-development of ordinary wildfires into awful fire disasters. (3) Difficulties in delivery and use of heavy machines on hardly accessible territories. (4) Absence of a perfect technique for economic evaluation of how effectively the wildfire control system works. (5) Absence of the system of payments encouraging wildfire fighters. To solve the problem of wildfires in Russia it is necessary to: (1) Create the Russian wildfire behaviour and fire effects prediction system on the basis of the developed classification of vegetation fuels and methods of their mapping as well as maximum utilization of forest inventory information and Geographic Information System (GIS). (2) Elaborate a technique of proper wildfire monitoring including estimation of vegetation damage. (3) Improve daily rating of regional fire danger. (4) Improve fire-preventive arrangement of the territory covered by vegetation, the main goal being creation of favourable conditions for active fire management. (5) Choose the main direction in elaboration of fire-fighting means and methods taking into account their universality, simplicity, reliability, etc. (6) Elaborate an improved technique for estimation of economic effectiveness of the wildfire control system. (7) Develop international cooperation of scientists and professionals in fire management.

Аннотация: The results of experimental studies on the contribution of zoogenic debris to transformation of soil properties in the southern taiga subzone of Central Siberia are analyzed. They show that water-soluble carbon outflow from the forest litter increases by 21-26% upon a Siberian moth invasion, with this value decreasing to 14% one year later. The burning of forest in an area completely defoliated by the pest leads to changes in the stock, fractional composition, actual acidity, and ash element contents of the litter. The litter-dwelling invertebrate assemblage is almost completely destroyed by fire and begins to recover only after two years.

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: For about three decades, there have been many predictions of the potential ecological response in boreal regions to the currently warmer conditions. In essence, a widespread, naturally occurring experiment has been conducted over time. In this paper, we describe previously modeled predictions of ecological change in boreal Alaska, Canada and Russia, and then we investigate potential evidence of current climate-induced change. For instance, ecological models have suggested that warming will induce the northern and upslope migration of the treeline and an alteration in the current mosaic structure of boreal forests. We present evidence of the migration of keystone ecosystems in the upland and lowland treeline of mountainous regions across southern Siberia. Ecological models have also predicted a moisture-stress-related dieback in white spruce trees in Alaska, and current investigations show that as temperatures increase, white spruce tree growth is declining. Additionally, it was suggested that increases in infestation and wildfire disturbance would be catalysts that precipitate the alteration of the current mosaic forest composition. In Siberia, 7 of the last 9 yr have resulted in extreme fire seasons, and extreme fire years have also been more frequent in both Alaska and Canada. In addition, Alaska has experienced extreme and geographically expansive multi-year outbreaks of the spruce beetle, which had been previously limited by the cold, moist environment. We suggest that there is substantial evidence throughout the circumboreal region to conclude that the biosphere within the boreal terrestrial environment has already responded to the transient effects of climate change. Additionally, temperature increases and warming-induced change are progressing faster than had been predicted in some regions, suggesting a potential non-linear rapid response to changes in climate, as opposed to the predicted slow linear response to climate change.

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: Data on the postfire dynamics of soil properties in the foci of Siberian moth population outbreaks are considered. It has been shown that controlled fires set in pest-defoliated forests result in the loss of approximately 75% of carbon and 50% of nitrogen from the forest litter through their emission into the atmosphere and in the enrichment of the upper soil horizons with potassium and phosphorus (this concerns both total and movable forms). Microbiological processes in the organogenic horizon undergo significant transformation, the density of microarthropods decreases, and the abundance of mites becomes hundreds of times lower.

Аннотация: The experimental data on the transformation of properties of soddy-deeply podzolic soils and raw humus burozems under fir forests defoliated by the Siberian moth Dendrolimus sibiricus are analyzed. In the first two months after the addition of Siberian moth excrements to the forest litter, the population of all ecological-trophic groups of microorganisms was shown to increase by 13 times, that of ammonifying phototrophs and microorganisms, taking part in humus mineralization, by 42 and 9 times, respectively. The leaching of water-soluble carbon from litters in forests defoliated by the Siberian moth was by 21-26% higher than that from litters of control ones. A year later, it was reduced to 14%. The content of exchangeable hydrogen and total acidity decreased, and the degree of base saturation increased. Within 5-6 years after the Siberian moth invasion, the transformation of physicochemical, chemical, and microbiological properties of soils was specified by succession development of the plant cover.

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: A game theory model of insect population dynamics is proposed. For the case when the population may be in one of two states: when physiological processes are directed to growth and reproduction, and when physiological processes are directed to the development of defense reactions, outbreaks of mass reproduction of insect populations may occur in conditions when population and environment have the <>, and the state of population and environment depends on their state at the previous time moment. In the framework of the model, the well known effect of insect phase variation during the outbreak of reproduction is explained.

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: PRATIQUE is an EC-funded 7th Framework research project designed to address the major challenges for pest risk analysis (PRA) in Europe. It has three principal objectives: (a) to assemble the datasets required to construct PRAs valid for the whole of the EU, (b) to conduct multi-disciplinary research that enhances the techniques used in PRA and (c) to provide a decision support scheme for PRA that is efficient and user-friendly. The research will be undertaken by scientists from 13 institutes in the EU and one each from Australia and New Zealand with subcontractors from institutes in China and Russia. They will produce a structured inventory of PRA datasets for the EU and undertake targeted research to improve existing procedures and develop new methods for (a) the assessment of economic, environmental and social impacts, (b) summarising risk while taking account of uncertainty, (c) mapping endangered areas (d) pathway risk analysis and systems approaches and (e) guiding actions during emergencies caused by outbreaks of harmful organisms. The results will be tested and provided as protocols, decision support systems and computer programs with examples of best practice linked to a computerised European and Mediterranean Plant Protection Organization (EPPO) PRA scheme.

Аннотация: The latest catastrophic Siberian silkmoth (Dendrolimus superans sibiricus Tschetw.) outbreak occurred in central Siberia during 1994-1996. The relationship between forest stand mortality from insects and topographic features (azimuth, elevation, slope steepness) was analyzed based on a high-resolution digital elevation model, a pest damage map and Terra/MODIS data. It was found that pest-induced forest mortality patterns depend on topographic features. Before the outbreak the major part of host forest species was found within the elevation zone of 150-500 m. After the outbreak, surviving dark-needle stands were found mainly at elevations higher than 400 m. The greatest damage was observed at elevations between 210 and 320 m, whereas maximum mortality was observed at elevations of about 200 m and minimal mortality at elevations of 300 m. With respect to slope steepness, maximum damage for all categories was observed for slopes of 5-20В°. Slightly damaged stands were most common at low slope angle (about 5В° or less), whereas the highest proportion of stands with high tree mortality was found on steeper slopes. With respect to azimuth, insect damage is mostly uniform, with a small increase in damage on the south-west-facing slopes. The spatial pattern of the silkmoth outbreak can provide a basis for prioritizing Siberian silkmoth outbreak monitoring. В© 2007 Taylor & Francis.

Аннотация: A game theory model of insect population dynamics is proposed. In the simplest case-when a population can be in one of two states, in one of which the physiological processes in an individual are aimed at enhancing the growth and reproduction, and in the other the physiological processes are aimed at activating defense reactions of an individual-outbreaks of insect propagation occur when both the population and the habitat have a certain kind of memory, specifically, when the current states of the population and the habitat depend on their states at the preceding moment of time. The model proposed explains the well-known phenomenon of phase variation among insect individuals during the population outbreak. Copyright В© 2003 by MAIK "Nauka/ Interperiodica".

Аннотация: A large-scale outbreak of the Siberian moth (Dendrolimus sibiricus) in the forests of the Lower Angara valley region (1993-1996) was analyzed on the basis of NOAA/AVHRR imaagery. The applicability of this type of imagery for detecting the foci of damage of tree stands with the discrimination of strong (50-75%) and very strong (>75%) dying and dead trees is demonstrated. The applicability of data from a winter survey was determined by the discovery of damaged tree stands. Summer/winter images were used in demarcating the northern boundary of the focal propagation of the Siberian moth.
