Аннотация: This monograph generalizes the results of multiyear studies on natural interspecific hybridization in woody plants and shows the key importance of the understanding of this widespread phenomenon for improving our knowledge of woody plant evolution, taxonomy, and breeding. Methodologies and results of the investigation on hybrid population structure are presented for genera Larix, Picea, Betula, Alnus, Caragana, and ribes found in Siberia. A list of natural interspecific hybrids in the woody plants growing within the former USSR is first included in this book.

A SIBERIAN VEGETATION MODEL-BASED ON CLIMATIC PARAMETERS

Аннотация: A model for predicting the spatial distribution of the major vegetation zones in Siberia is developed from bioclimatological considerations. Driving variables are growing degree-days (5 degrees C base), Budyko's dryness index, and Conrad's continentality index. Because these indices reflect the underlying climatic factors determining plants' requirements for warmth, drought resistance, and cold tolerance, they define the main features of vegetation zonation. Climatic inputs (monthly mean temperature, precipitation, vapor pressure, cloudiness, and albedo) are obtained from a global climatic database, supplemented by additional weather stations in Siberia; resolution is 0.5 degrees longitude by 0.5 degrees latitude. The performance of the model is examined by comparing our Siberian vegetation predictions with the landscape map of the USSR by Isachenko, a map that was not used for model development. The patterns of vegetation predicted by the Siberian vegetation model generally match well with the vegetation patterns on Isachenko's map. The general locations of all vegetation zones are predicted correctly. This visual impression is also borne out statistically, with K-statistics for judging agreement between the maps showing good agreement (0.55 kappa 0.7) at all scales of comparison (from 0.5 degrees by 0.5 degrees pixels to 5 degrees by 5 degrees blocks of pixels). The model is also useful for estimating the change in equilibrium conditions due to hypothesized events such as CO2-induced global warming, for retrospective comparisons using the paleorecord, and for carbon budget assessment.

Impacts of air pollution on far north forest vegetation

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.

The use of aerospace methods for forest state assessment

Аннотация: Siberian forest occupy a significant part of the Asian continent. Their role as an essential component of the Earth's surface, biomass and oxygen producer is increasing annually. Expanded reproduction of taiga forests necessitated by the intensive development of Siberian productive forces, results in an evergrowing need of forest productivity constancy and increase. Proper forest exploitation is a crucial part of the solution of such important problems as the rational use of land and water resources, stable crop yields, and the creation of favourable conditions for human life. To solve these important economic problems, the Siberian branch of the USSR Academy of Sciences has devised a long-term programme of ecological monitoring of Siberian forest resources using aerospace techniques. The programme provides for the establishment and improvement of ecogeographical and physicotechnological principles of the remote sensing of forest and the development of fundamental forest-biological research based on new methodologies, the results of which are used to solve urgent forestry and nature protection problems. The research is carried out in the following major directions: studying spectral characteristics of forest vegetation for forest-state indication; thematic mapping of taiga territories; assessing biological productivity of natural complexes; environmental state monitoring; fire protection of forest; pest and disease control; developing instruments and methods for automatized aerospace data processing for real-time use. We consider forest-state monitoring to be one of the crucial tools in providing the optimum use of forest ecosystems for resource and ecological functions.

Аннотация: The thickness and reserves of litter are shown to increase with impeded drainage of habitats of a topoecological profile. This leads to a less favorable soil temperature regime, slower rate of liter decomposition, and accumulation in the carbon and nitrogen supply of many inert nonhydrolyzable compounds, thereby, adversely affecting the productivity of tree stands. -Journal summary

Аннотация: An article devoted to applied forest-fire mapping outlines principles for the compilation of maps depicting 'raw materials' for such fires. Various types and densities of vegetation cover are classified in terms of combustibility, i.e., according to the intensity of burning expected once they are fully exposed to flames. These maps are used in conjunction with weather data and forecasts to predict and combat the spread of fire across an area. -Journal summary

Аннотация: Geosciences Laser Altimeter System (GLAS) space LiDAR data are used to attribute a MODerate resolution Imaging Spectrometer (MODIS) 500В m land cover classification of a 10В° latitude by 12В° longitude study area in south-central Siberia. Timber volume estimates are generated for 16 forest classes, i.e., four forest cover types ? four canopy density classes, across this 811,414В km 2 area and compared with a ground-based regional volume estimate. Two regional GLAS/MODIS timber volume products, one considering only those pulses falling on slopes ? 10В° and one utilizing all GLAS pulses regardless of slope, are generated. Using a two-phase(GLAS-ground plot) sampling design, GLAS/MODIS volumes average 163.4 В± 11.8В m 3/ha across all 16 forest classes based on GLAS pulses on slopes ? 10В° and 171.9 В± 12.4В m 3/ha considering GLAS shots on all slopes. The increase in regional GLAS volume per-hectare estimates as a function of increasing slope most likely illustrate the effects of vertical waveform expansion due to the convolution of topography with the forest canopy response. A comparable, independent, ground-based estimate is 146В m 3/ha [Shepashenko, D., Shvidenko, A., and Nilsson, S. (1998). Phytomass (live biomass) and carbon of Siberian forests. Biomass and Bioenergy, 14, 21-31], a difference of 11.9% and 17.7% for GLAS shots on slopes ? 10В° and all GLAS shots regardless of slope, respectively. A ground-based estimate of total volume for the entire study area, 7.46 ? 10 9В m 3, is derived using Shepashenko et al.'s per-hectare volume estimate in conjunction with forest area derived from a 1990 forest map [Grasia, M.G. (ed.). (1990). Forest Map of USSR. Soyuzgiproleskhoz, Moscow, RU. Scale: 1:2,500,000]. The comparable GLAS/MODIS estimate is 7.38 ? 10 9В m 3, a difference of less than 1.1%. Results indicate that GLAS data can be used to attribute digital land cover maps to estimate forest resources over subcontinental areas encompassing hundreds of thousands of square kilometers.
