Аннотация: While the forest-tundra zone in Siberia, Russia has been dendroclimatologically well-studied in recent decades, much less emphasis has been given to a wide belt of northern taiga larch forests located to the south. In this study, climate and local site conditions are explored to trace their influence on radial growth of Gmelin larch (Larix gmelinii (Rupr.) Rupr.) trees developed on permafrost soils in the northern taiga. Three dendrochronological sites characterized by great differences in thermo-hydrological regime of soils were established along a short (ca. 100 m long) transect: on a river bank (RB), at riparian zone of a stream (RZ) and on a terrace (TER). Comparative analysis of the rate and year-to-year dynamics of tree radial growth among sites revealed considerable difference in both raw and standardized tree-ring width (TRW) chronologies obtained for the RZ site, characterized by shallow soil active layer depth and saturated soils. Results of dendroclimatic analysis indicated that tree-ring growth at all the sites is mostly defined by climatic conditions of a previous year and precipitation has stronger effect on TRW chronologies in comparison to the air temperatures. Remarkably, a great difference in the climatic response of TRW chronologies has been obtained for trees growing within a very short distance from each other. The positive relation of tree-ring growth with precipitation, and negative to temperature was observed in the dry site RB. In contrary, precipitation negatively and temperature positively influenced tree radial growth of larch at the water saturated RZ. Thus, a complicate response of northern Siberian larch forest productivity to the possible climate changes is expected due to great mosaic of site conditions and variability of environmental factors controlling tree-ring growth at different sites. Our study demonstrates the new possibilities for the future dendroclimatic research in the region, as various climatic parameters can be reconstructed from tree-ring chronologies obtained for different sites.

Аннотация: The elevational tree-line change within the transitional zone between boreal forest and Mongolian steppes was quantified for the last millennium. The basic approach included studies along transects and measurements of tree-line positions to identify current, historical, refugee and regeneration tree lines. Tree mortality and natality were determined based on dendrochronology analysis. Tree mortality in the sixteenth to eighteenth centuries coincided with the Little Ice Age, while tree establishment was stimulated by warming at the end of nineteenth century. Downward shifts in tree line varied by an order of magnitude. The current tree-line position reoccupied the historical tree line in some transects, and was below or above the historical line in others. The regeneration line surpassed the historical tree line by 91 +/- 46 m (mean +/- SD). Such a heterogeneous response was attributed to local topoclimatic conditions and sapling recruitment efficiency. A mean annual 1 degrees C increase in temperature was associated with an upward shift of the tree line by about 70 m. The upward migration rate of the current tree line was about 0.8 m year-1 during the last century. The regeneration migration rate was about 2.3 m year-1 over the past three decades. Finally, the transformation of krummholz forms of larch and Siberian pine into arborescent form was documented.

Аннотация: We compared effects of ambient (360 vpm) and elevated (720 vpm) carbon dioxide concentration ([CO(2)]) and high and low nutrient supply rates on stem growth, annual ring structure and tracheid anatomy of Siberian larch (Larix sibirica Ledeb.) seedlings over two growing seasons. Elevated [CO(2)] had no significant effect on either stem height or diameter growth; however, both stem height and diameter growth were enhanced by the high nutrient supply rate, and these increases were stimulated by elevated [CO(2)]. Elevated [CO(2)] tended to increase the width of the annual xylem ring, the number of cells in a radial file spanning the ring, and tracheid lumen diameter, whereas it tended to reduce cell wall thickness, although there were no statistically significant CO(2) effects on tracheid anatomy. Changes in tracheid cell morphology seemed to be dependent on changes in shoot elongation rates.

Аннотация: Two quantitative methods were used to reconstruct paleoenvironments and vegetation in the Altai-Sayan mountains, Central Asia, during the Holocene. The 'biomization' method of Prentice et al (1996 Clim. Dyn. 12 185-96), applied to the surface pollen record, worked fairly well in the reconstructions of current vegetation. Applying this method to fossil pollen data, we reconstructed site paleovegetation. Our montane bioclimatic model, MontBioCliM, was used inversely to convert site paleovegetation into site paleoclimates. The differences between site paleo and current climates served as past climate change scenarios. The climatic anomalies for 2020, 2050, and 2080 derived from HadCM3 A1FI and B1 of the Hadley Centre, UK, served as climate change scenarios in the 21st century. MontBioCliM was applied directly to all climate scenarios through the Holocene to map past and future mountain vegetation over the Altai-Sayan mountains. Our results suggest that the early Holocene ca 10 000 BP was cold and dry; the period between 8000 and 5300 BP was warm and moist; and the time slice ca 3200 BP was cooler and drier than the present. Using kappa statistics, we showed that the vegetation at 8000 BP and 5300 BP was similar, as was the vegetation at 10 000 BP and 3200 BP, while future vegetation was predicted to be dissimilar to any of the paleovegetation reconstructions. The mid-Holocene is frequently hypothesized to be an analog of future climate warming; however, being known as warm and moist in Siberia, the mid-Holocene climate would likely impact terrestrial ecosystems differently from the projected warm and dry mid-century climate.

Аннотация: Tree-ring anatomical structure is the key to understanding of adaptive specifics of xylem of various species to climate change. This is especially significant in the permafrost zone due to likely permafrost degradation. We compared anatomic features of annual rings of Dahurian larch (Larix gmelinii (Rupr.) Rupr., Larix cajanderi Mayr.), Scots pine (Pinus sylvestris L.) and Siberian spruce (Picea obovata Ledeb.) growing in the permafrost zone in Central Siberia for 1960-2011. Climatic factors affecting tree radial growth and anatomic features of tracheids of coniferous species were revealed.

Аннотация: The forest-steppe ecotone in southern Siberia is the natural transition zone from the dry steppe in the south to the wetter taiga in the north, where tree growth is increasingly limited due to drought. Within this zone, tree growth limitation is expected to intensify due to ongoing climate changes, reducing forest productivity, affecting tree physiological processes and increasing tree mortality, with potential implications for the regional and global carbon cycle. We explored Pinus sylvestris L. tree ring growth and structure response to climate in southern Siberia. We measured tree-ring width (RW) and xylem parenchyma represented as the percentage of ring surface occupied by parenchyma rays (PERPAR) and the total amount of ray parenchyma per sample width (TOTRAY) within the growth rings for the 1967-2018 period. The results showed an influence of environmental conditions before and during the formation of ray parenchyma, with an independent climate response from the observed in the RW. Therefore, pine xylem parenchyma-based chronologies have potential as a proxy to evaluate climate sensitivity in P. sylvestris. However, the dependence on climate conditions might affect ray parenchyma's critical role in conifers as P. sylvestris under the current temperature-induced drought trend in the forest-steppe.

Аннотация: Plants can minimise the damaging effects of high temperatures through numerous protective mechanisms; however, it is largely unknown how these mechanisms respond to extreme temperatures associated with wildfire. We investigated the effect of experimental burning (EB) on the accumulation of stress heat shock proteins (Hsps), which are one of the factors of thermotolerance in plants, in the needles of Scots pine (Pinus sylvestris L.). Previous fire exposure led not only to short- and long-term changes in the content of stress proteins in needles but also to changes in the accumulation of these proteins in response to reheating. The content of Hsp 101, Hsp 70 and Hsp 17.6 in the needles increased on the second day after EB (short-term effect of fire). Three years after EB, the content of Hsps in the fire-exposed needles was lower compared with the control needles. When these needles were subjected to the heat stress test at 45 degrees C, the content of Hsps increased, whereas the content of Hsps in control needles decreased. Our results suggest that Scots pine needles retain a fairly long-term 'stress memory', expressed through proteomic defence mechanisms, to wildfire heat-induced damage.
