    Carbon and water exchanges of regenerating forests in central Siberia
/ M. Meroni, N. Tchebakova // Forest Ecology and Management. - 2002. - Vol. 169, № 1-2. - С. 115-122

Аннотация: Direct measurements of CO2 and water vapour of regenerating forests after fire events (secondary succession stages) are needed to determine the role of such disturbances in the biome carbon and water cycles functioning. An estimation of the extension of burnt areas is also required in order to quantify NBP (net biome productivity), a variable that includes large-scale carbon losses (such as fire) bypassing heterotrophic respiration. Hence, eddy covariance measurements Of CO2 and water vapour were carried out in a natural regenerating forest after a fire event. Measurements were collected continuously over a Betula spp. stand in central Siberia during summer 1999. Minimum carbon exchange rate (NEE, net ecosystem exchange) exceeded -30 mumol m(-2) s(-1) (net flux negative indicating CO2 uptake by vegetation) and the partitioning of the available energy was mostly dominated by latent heat flux. Structure, age and composition of the forest were analysed to understand the secondary succession stages. The results were compared with previous studies on coniferous forests where biospheric exchanges of energy were dominated by sensible heat fluxes and small carbon uptake rates, thus indicating rather limiting growing conditions. A classification of a Landsat-4 Thematic Mapper scene has been carried out to determine the magnitude of burnt areas and the extension of broadleaf regenerating forests. Analysis of burnt areas spatial frequency and carbon exchanges of the regenerating forest stress the importance of considering large area disturbances for full carbon accounting.

Аннотация: The approach to the estimation of mountain forest ecosystems in Altai-Sayan ecoregion is developed using bioclimatic classification of altitudinal belt complexes (abc) of forest types. The main characteristics and distribution of climate facies (groups of cyclonic and anticyclonic regions) are presented. The data base on biodiversity, climate and soils is added with new remote sensing data. The approach is aimed to find the optimal balance between different ways of multiple forest management keeping high environmental and social function of ecosystems and biogeocoenoses.

Аннотация: Arctic environments, where surface temperatures increase and sea ice cover and permafrost depth decrease, are very sensitive to even slight climatic variations. Placing recent environmental change of the high-northern latitudes in a long-term context is, however, complicated by too short meteorological observations and too few proxy records. Driftwood may represent a unique cross-disciplinary archive at the interface of marine and terrestrial processes. Here, we introduce 1445 driftwood remains from coastal East Greenland and Svalbard. Macroscopy and microscopy were applied for wood anatomical classification; a multi-species subset was used for detecting fungi; and information on boreal vegetation patterns, circumpolar river systems, and ocean current dynamics was reviewed and evaluated. Four conifer (Pinus, Larix, Picea, and Abies) and three deciduous (Populus, Salix, and Betula) genera were differentiated. Species-specific identification also separated Pinus sylvestris and Pinus sibirica, which account for similar to 40% of all driftwood and predominantly originate from western and central Siberia. Larch and spruce from Siberia or North America represents similar to 26% and similar to 18% of all materials, respectively. Fungal colonization caused different levels of driftwood staining and/or decay. Our results demonstrate the importance of combining wood anatomical knowledge with insight on boreal forest composition for successfully tracing the origin of Arctic driftwood. To ultimately reconstruct spatiotemporal variations in ocean currents, and to better quantify postglacial uplift rates, we recommend consideration of dendrochronologically dated material from many more circumpolar sites.

Аннотация: Information on land cover at global and continental scales is critical for addressing a range of ecological, socioeconomic and policy questions. Global land cover maps have evolved rapidly in the last decade, but efforts to evaluate map uncertainties have been limited, especially in remote areas like Northern Eurasia. Northern Eurasia comprises a particularly diverse region covering a wide range of climate zones and ecosystems: from arctic deserts, tundra, boreal forest, and wetlands, to semi-arid steppes and the deserts of Central Asia. In this study, we assessed four of the most recent global land cover datasets: GLC-2000, GLOBCOVER, and the MODIS Collection 4 and Collection 5 Land Cover Product using cross-comparison analyses and Landsat-based reference maps distributed throughout the region. A consistent comparison of these maps was challenging because of disparities in class definitions, thematic detail, and spatial resolution. We found that the choice of sampling unit significantly influenced accuracy estimates, which indicates that comparisons of reported global map accuracies might be misleading. To minimize classification ambiguities, we devised a generalized legend based on dominant life form types (LFT) (tree, shrub, and herbaceous vegetation, barren land and water). LFT served as a necessary common denominator in the analyzed map legends, but significantly decreased the thematic detail. We found significant differences in the spatial representation of LFT's between global maps with high spatial agreement (above 0.8) concentrated in the forest belt of Northern Eurasia and low agreement (below 0.5) concentrated in the northern taiga-tundra zone, and the southern dry lands. Total pixel-level agreement between global maps and six test sites was moderate to fair (overall agreement: 0.67-0.74, Kappa: 0.41-0.52) and increased by 0.09-0.45 when only homogenous land cover types were analyzed. Low map accuracies at our tundra test site confirmed regional disagreements and difficulties of current global maps in accurately mapping shrub and herbaceous vegetation types at the biome borders of Northern Eurasia. In comparison, tree dominated vegetation classes in the forest belt of the region were accurately mapped, but were slightly overestimated (10%-20%), in all maps. Low agreement of global maps in the northern and southern vegetation transition zones of Northern Eurasia is likely to have important implications for global change research, as those areas are vulnerable to both climate and socio-economic changes.

Аннотация: The Northern Eurasian land mass encompasses a diverse array of land cover types including tundra, boreal forest, wetlands, semi-arid steppe, and agricultural land use. Despite the well-established importance of Northern Eurasia in the global carbon and climate system, the distribution and properties of land cover in this region are not well characterized. To address this knowledge and data gap, a hierarchical mapping approach was developed that encompasses the study area for the Northern Eurasia Earth System Partnership Initiative (NEESPI). The Northern Eurasia Land Cover (NELC) database developed in this study follows the FAO-land Cover Classification System and provides nested groupings of land cover characteristics, with separate layers for land use, wetlands, and tundra. The database implementation is substantially different from other large-scale land cover datasets that provide maps based on a single set of discrete classes. By providing a database consisting of nested maps and complementary layers, the NELC database provides a flexible framework that allows users to tailor maps to suit their needs. The methods used to create the database combine empirically derived climate-vegetation relationships with results from supervised classifications based on Moderate Resolution Imaging Spectroradiometer (MODIS) data. The hierarchical approach provides an effective framework for integrating climate-vegetation relationships with remote sensing-based classifications, and also allows sources of error to be characterized and attributed to specific levels in the hierarchy. The cross-validated accuracy was 73% for the land cover map and 73% and 91% for the agriculture and wetland classifications, respectively. These results support the use of hierarchical classification and climate-vegetation relationships for mapping land cover at continental scales. (C) 2010 Elsevier Inc. All rights reserved.

    Landscape controls of CH4 fluxes in a catchment of the forest tundra ecotone in northern Siberia
[Text] / H. . Flessa [et al.] // Glob. Change Biol. - 2008. - Vol. 14, Is. 9. - P2040-2056, DOI 10.1111/j.1365-2486.2008.01633.x. - Cited References: 68 . - 17. - ISSN 1354-1013

Аннотация: Terrestrial ecosystems in northern high latitudes exchange large amounts of methane (CH4) with the atmosphere. Climate warming could have a great impact on CH4 exchange, in particular in regions where degradation of permafrost is induced. In order to improve the understanding of the present and future methane dynamics in permafrost regions, we studied CH4 fluxes of typical landscape structures in a small catchment in the forest tundra ecotone in northern Siberia. Gas fluxes were measured using a closed-chamber technique from August to November 2003 and from August 2006 to July 2007 on tree-covered mineral soils with and without permafrost, on a frozen bog plateau, and on a thermokarst pond. For areal integration of the CH4 fluxes, we combined field observations and classification of functional landscape structures based on a high-resolution Quickbird satellite image. All mineral soils were net sinks of atmospheric CH4. The magnitude of annual CH4 uptake was higher for soils without permafrost (1.19 kg CH4 ha(-1) yr(-1)) than for soils with permafrost (0.37 kg CH4 ha(-1) yr(-1)). In well-drained soils, significant CH4 uptake occurred even after the onset of ground frost. Bog plateaux, which stored large amounts of frozen organic carbon, were also a net sink of atmospheric CH4 (0.38 kg CH4 ha(-1) yr(-1)). Thermokarst ponds, which developed from permafrost collapse in bog plateaux, were hot spots of CH4 emission (approximately 200 kg CH4 ha(-1) yr(-1)). Despite the low area coverage of thermokarst ponds (only 2.1% of the total catchment area), emissions from these sites resulted in a mean catchment CH4 emission of 3.8 kg CH4 ha(-1) yr(-1). Export of dissolved CH4 with stream water was insignificant. The results suggest that mineral soils and bog plateaux in this region will respond differently to increasing temperatures and associated permafrost degradation. Net uptake of atmospheric CH4 in mineral soils is expected to gradually increase with increasing active layer depth and soil drainage. Changes in bog plateaux will probably be much more rapid and drastic. Permafrost collapse in frozen bog plateaux would result in high CH4 emissions that act as positive feedback to climate warming.

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.

    Mapping of Siberian forest landscapes along the Yenisey transect with AVHRR
[Text] / V. I. Kharuk [et al.] // Int. J. Remote Sens. - 2003. - Vol. 24, Is. 1. - P23-37, DOI 10.1080/0143116021000021143. - Cited References: 30 . - 15. - ISSN 0143-1161

Аннотация: In this paper NOAA AVHRR data acquired at the Sukachev Institute of Forest in Siberia, Russia is evaluated for forest management mapping applications. First a classification of the entire 1000 km x 3000 km transect was performed, but was found to be too general to be of value. More useful interpretation procedures require a landscape-ecological approach. This means that computer classification should be made separately for segments of territory based ecologically distinct regions. This segmentation of the transect into ecological regions was found to improve the level of detail available in the classification. Using this approach AVHRR data were found to be adequate for small scale mapping at the level of vegetation types or plant formations. A limited study using AVHRR data for classification of mountainous regions showed that AVHRR-derived maps were more detailed than existing landscape maps. AVHRR derived classifications also compared favourably to larger scale forest management maps of softwood and hardwood forests. Current forest management in Siberia relies on very small-scale inventory maps. Thus, there is a potential role for AVHRR (or Terra) data for northern Siberian forest monitoring. The southern forests of the Yenisey meridian (below the 57th parallel) are less uniform due to considerable human activity, and NOAA/AVHRR data will play a subordinate role in its monitoring.

Those areas represent a variety of the main ecosystem and physical-geographical conditions from the tundra to the southern taiga (forest) zones. The analysis of Radarsat signal amplitude, textural characteristics and digital elevation fused data allowed the detection of 18 onground classes. For the purpose of classification the importance of parameters arrange as follows: relief, signal amplitude, skewness, variance, mean Euclidean distance and kurtosis. The main advantage of the Radarsat data is its ability to detect hydromorphic elements (7 bog types were determined).

Аннотация: This paper study considers the effects of oil exploration and development in the oilfields of Evenkiya, Central Siberia (60degrees30'N/96degrees30'E). The drilling in this area was initiated in 1970, and the first oil was extracted in 1977. Image data from the US' Landsat - 7, the Russian "Resours", and the European ERS-2 remote sensing satellites were analyzed. The information value of the Landsat-7channels was evaluated. In particular, the fresh oil drilling sites effectively differ from old ones in the third (0.63-0.69 mum) and fourth (0.75-0.90 mum) channels. Recently burned areas are detectable in the middle IR (1.55-1.75, 2.08-2.35 mum). The classification accuracy depends on the number of channels used, but does not improve greatly using more than 4 or 5 channels. Landsat - 7 scenes enable the detection of patterns for parallel strips (5 - 10 in in width) of cut forest, the first sign of the oil reconnaissance. Alongside the direct impacts of oil-exploitation, fire frequency was increased. The "big" fires (area > 200 ha) caused similar to90% of the total damage, but only accounted for 10% of total firescars. The area of human-caused impact is similar to20% of territory, which is similar to2.5 higher than average for known oil development areas within the Landsat scene. The ERS-2 scenes were found to be effective for mapping fresh drilling sites only. The comparative analysis of "Resours" KFA-1000 camera scene (June 1984) and Landsat-7 (October 1999) showed that during this period the number of oilrigs increased nearly 5 times. Generally, the Landsat-7 data are effective for early detection of the anthropogenic impact on the Siberian larch-dominated communities.

    The models ''resource-consumer'' taking into consideration the quantitative changes of resource

Аннотация: The authors consider three interaction models ''resource - consumer''. ''Null model'' is basic for the rest ones because in its frame the antibiosis of feeding objects does not take into consideration. According to reparation model feeding objects be either accessible for consumption or exist in reparation state if the high concentration of protection substances does not allow the population of consumers to continue feeding. Complicated model includes three states of feeding object: it is accessible and not attacked by insects, it is accessible and attacked and feeding object exists in reparation state. This model takes into consideration a set of different effects, for instance the effect of slow development of reparation processes. The changes taking place under pollution influence with different parameters of ''resource - consumer''interaction are characterised. The authors suggest the classification of different ''resource - consumer'' models based on resource characters. All models show the exponential decrease in the portion of non-damaged feeding objects while they contact with consumers. Change of this portion allows to measure the rate of consumer attack, whereas the dynamic of total number of damages characterizes the reparation characteristics. The authors investigate the damage of Populus leaves by insects in plots situated in Krasnoyarsk in regions with different antropogenic influence. The dynamic of damages shows the high degree of consent with the models. They can be useful for entomological indication to evaluate the state of separate trees or the whole stand.

Аннотация: The application of multiparametric statistical methods has confirmed that peat soils are different in the degree of their drainage and properties because of their modification during a 20 - 25 year period of artificial drainage operation. The following sequence represents the relative significance of the contribution to the soil changes of the parameters studied: groundwater table air capacity pH T-0 Eh water-soluble: C Fe3+ and the activity of soil oxidoreductases in the following sequence: peroxidase catalase dehydrogenase. The necessity to supplement the substantive - genetic principle of the classification of drained peat soils with characterization of their water regime is substantiated.

Аннотация: In the litters (peaty, weakly decomposed, and strongly decomposed) of bog birch forests, the biochemical transformation of plant material includes several discrete stages. The best prediction of the decomposition stages is the set of indices characterizing the humus status of the soils: the C/N ratio, (I HA pound + I FA) pound/C(polysaccharides), and the contents of humic and fulvic acids of fraction 1 in the groups of plant debris of different sizes. The discrimination of the litters according to the level of the biochemical transformation of the organic residues was observed when using the (I HA pound + I FA) pound/C(polysaccharides) ratio, which is 6.3 in the peaty litter and 11.2 and 18.4 in the weakly decomposed and strongly decomposed litters, respectively. The biochemical classification of litters in the bog birch forests is in agreement with the morphological classification of litters.

Аннотация: Being of global ecological significance, boreal forests of Siberia located at the high latitudes of Northern Eurasia serve as a unique source of genetic, species, and ecosystem diversity. Previously conducted research revealed a wide range of scientific problems regarding the intraspecific diversity of trees, estimation of the structure and current state of forest ecosystems, as well as their ordination and classification. The use of modem information technologies (databases, species diversity indices, GIS) can promote the knowledge on Siberian boreal forests to a higher level.
