Аннотация: Tree ring width, density, and ratio of stable isotopes (C-13/C-12 and O-18/O-16) in wood and cellulose were determined for larch (Larix sibirica Ledeb.) growing under water deficit conditions in the forest steppe zone in central Siberia (54 degrees 24'N, 89 degrees 57'E) for the period 1850-2005. Dendroclimatic analysis of the chronologies indicated precipitation to be the most important factor determining indicated parameters. Precipitation of June is significantly correlated with tree ring width and maximum density (r = 0.36 and 0.43, p 0.05, respectively). Relations of delta C-13 and delta O-18 to precipitation are similar, but the most important month is July (r

Аннотация: Regional tree ring chronology with extension 2209 years (from 212 B.C. till 1996 A.D.) was built for east Taymir and Putoran according to wood of living trees, well- preserved remains of dead trees, and subfossil wood from alluvial bank deposits by the cross-dating method. In addition, the "floating" tree ring width chronology for the period of Holocene optimum (3300-2600 B.C.) was built with extention 685 years and supported by several radiocarbon dates. High values of synchrony and correlation of individual tree ring series show a prevailing effect of one external factor on radial tree growth change in the studied region of the Siberian subarctic. It was established that the main factors of growth variability are the early summer and annual temperature, which explain up to 70% of tree growth rate variability. Cyclic components stable for two millennia were revealed at analysis of the tree ring chronology: double secular (similar to 180 years), secular (78-90 years), and intrasecular (44, 28, 11, and 6.7-6.9 years) variations. Models for reconstruction of the early summer and annual air temperature were obtained according to tree ring variability. Temperature dynamics in the eastern part of Taymir for the last two millenia agree well with temperature variations in the Northern Hemisphere obtained according to other indirect sources. The warming of the middle of the twentieth century is not extraordinary. The warming at the end of the first and beginning of the second millennia ("Medieval Warm Period") was longer in time and closer in amplitude.

Аннотация: Fossil pollen data supplemented by tree macrofossil records were used to reconstruct the vegetation of the Former Soviet Union and Mongolia at 6000 years. Pollen spectra were assigned to biomes using the plant-functional-type method developed by Prentice ct al. (1996). Surface pollen data and a modern vegetation map provided a test of the method. This is the first time such a broad-scale vegetation reconstruction for the greater part of northern Eurasia has been attempted with objective techniques. The new results confirm previous regional palaeoenvironmental studies of the mid-Holocene while providing a comprehensive synopsis and firmer conclusions. West of the Ural Mountains temperate deciduous forest extended both northward and southward from its modern range. The northern limits of cool mixed and cool conifer forests were also further north than present. Taiga was reduced in European Russia, but was extended into Yakutia where now there is cold deciduous forest. The northern limit of taiga was extended (as shown by increased Picea pollen percentages, and by tree macrofossil records north of the present-day forest limit) but tundra was still present in north-eastern Siberia. The boundary between forest and steppe in the continental interior did not shift substantially, and dry conditions similar to present existed in western Mongolia and north of the Aral Sea.

Аннотация: Tree-ring chronologies (dendrochronological time series) are an important proxy source for oblique high-resolution information about climate and environmental changes in the past and present. Often the time series signals are associated with direct external periodic forcing (e.g., annual irradiance, seasonal moisture regimes, etc.), or with the internal oscillations within biological systems themselves (e.g., age-dependent trends, components of competition, etc). In most cases, the observed signal is interpreted as superposition of different internal and external influences. In most cases due to unstable frequency, amplitude and phase of analyzed signals the significance of power spectrum peaks may be tested by the "red-noise" null hypothesis, with a number of additional assumptions concerning possible causes for the observed instability. The goal of this paper is to verify information losses in the case of testing a power spectrum by the "white-noise" null hypothesis in order to detect significant cycles in dendrochronological time series. The new approach described herein allows us to (1) obtain an adequate spectral decomposition of different tree-ring chronologies; (2) analyze spatial comparisons of different time series, specifying possible causes for disagreement; and (3) build new long-term reconstructions of different climatic series by different cyclical components. Moreover, the approach helps to extend super long-term tree-ring chronologies by low-frequency components, to verify temporal periods in the past for which there are no good statistical estimations, which will enable extension of existing climatic reconstructions.
