    Growth dynamics of conifer tree rings. Images of past and future environments
: монография / E. A. Vaganov, M. K. Hughes, A. V. Shashkin. - Berlin ; Heidelberg : Springer, 2006. - 358 с. : ил., табл. - (Ecological studies : analysis and Synthesis, ISSN 0070-8356 ; vol. 183). - Библиогр.: с. 311-342. - ISBN 3-540-26086-2 : Б. ц.

Аннотация: Each tree ring contains an image of the time when the ring formed, projected onto the ring's size, structure, and composition. Tree rings thus are natural archives of past environments, and contain records of past climate. While dendrochronologists have investigated the impact of climate on tree-ring growth by empirical-statistical methods. This volume presents a process-based model complementing previous approaches. Basic ideas concerning the biology of tree-ring growth and its control by environmental factors are treated, especially for conifers. The use of the model is illustrated by means of several examples from widely differing environments, and possible future directions for model development and application are discussed. The volume provides an improved mechanistic basis for the interpretation of tree rings as records of past climate. It advances process understanding of the large-scale environmental control of wood growth. As forests are the main carbon sink on land, the results are of great importance for all global change studies.

    Evidence of evergreen conifer invasion into larch dominated forests during recent decades in Central Siberia
: материалы временных коллективов / V. I. Kharuk, K. Ranson, M. Dvinskaya // Eurasian Journal of Forest Research. - 2007. - Vol. 10-2. - С. 163-171. - Библиогр. в конце ст.

Аннотация: Models of climate warming predict the migration of "warm-adapted' species to habitates of "cold-adapted" species. Here we show evidence of expansion of "dark-needle" conifers (DNC: Siberian pine, spruce and fir) into the habitat of larch, the leader in adaptation to harsh climatic conditions in Asia. The studies were made along two transects oriented from the western and southern borders of a larch dominated forest to its center. The invasion of DNC into the historical larch habitat was quantified as an increase of the proportion of those species both in the overstory and in regeneration. The age structure of regeneration showed that regeneration occurred mainly during the last 2-3 decades. In particular warm winter temperatures promote the survival regenerated Siberian pine. The results obtained indicate the climate-driven migration of Siberian pine, spruce and fir into traditional zone of larch dominance. Substitution of a deciduous conifer (larch) by evergreen conifers decreases the albedo and may provide positive feedback for temperature increases.

    Integrated approach to monitoring of the Siberian moth population density
: absracts / V. M. Pet'ko [и др.] // Enviromis. International conference on enviromental observations, modelling and information systems, Tomsk, Russia, July 1-8, 2006: program and abstracts. - 2006. - С. 95

Аннотация: The Siberian moth (SM), is the most destructive defoliator of conifers in Northern Asia. It could have a serious impact on native forests. The present day monitoring methods of SM populations density, based on trees shaking for larve sampling, are labor-intensive, expensive and require an optimization. Although larve sampling is an extremely expensive procedure, only its' results may be a basis for presribed insecticide spraying of pest population.

    Evidence of evergreen conifers invasion into larch dominated forests during recent decades
: материалы временных коллективов / V. I. Kharuk, K. J. Ranson, M. L. Dvinskaya // Environmental change in Siberia: earth observation, field studies and modelling. - Dordrecht et. al. : Springer, 2010. - С. 53-65. - Библиогр. в конце ст.

Аннотация: The results obtained indicate a DNC and birch invasion into a traditional larch domination zone, and the connection of this phenomenon with climatic trends during last decades. On the western and southern margions DNC regeneration formed a second layer in the forest canopies, which could eventually replace the larch in the overstory. Larch as a species also responds to climatic trends: its radial increment significantly increased during last 3 decades, and this increase correlates with summer temperatures and precipitation. The other larch response is the migration into the trundra zone and a crown closure increase, as was found on the key-sites "Polar Ural"and "Ary-Mas". The resulting effect of this process may be that larch could reach the Arctic shore, a phenomenon that has happened in a former epoch, whereas the traditional area of larch dominance will turn to mixed taiga forest.

Аннотация: This is a short review of our recent studies on trophic adaptation of a boreal forest pest, the Siberian moth in its native range, North Asia and in Central Europe where the species is believed to invade in a near future. In Europe, the hierarchy in suitability of host plant genera (increasing from two-needle pines, spruce, fir, to larch) remains similar to that in the pest range. Besides European plants, some North American conifers from genera which do not exist in the pest habitat can be served as potential hosts for the insect.

Аннотация: Warming induced (1) tree upward and northward migration and (2) krummholz transformation in alpine and northern ecotones, (3) a "dark needle conifers (DNC)" migration within "mixed taiga - zone of larch dominance" ecotone, (4) growth increment increase and stand denisification, (4) DNC proportion increase, which should lead an albedo decrease, amplifying warming at local scale. Observed radial and apical growth increment increases were correlated with both, air temperatures and atmospheric CO2 concentration increases.

    Fire return intervals within the northern boundary of the larch forest in Central Siberia

Аннотация: A fire history of northern larch forests was studied. These larch forests are found near the northern limit of their range at similar to 71 degrees N, where fires are predominantly caused by lightning strikes rather than human activity. Fire-return intervals (FRIs) were calculated based on fire scars and dates of tree natality. Tree natality was used as an approximation of the date of the last fire. The average FRI was found to be 295 +/- 57 years, which is the longest reported for larch-dominated stands. Prior studies reported 80-90-year FRIs at 64 degrees N and similar to 200 years near the latitude of the Arctic Circle. Comparing data from fires that occurred in 1700-1849 (end of the Little Ice Age, LIA) and 1850-1999 (post-LIA warming) indicates approximately twice as many fires occurred during the latter period. This agrees with the hypothesis that observed climatic warming will result in an increase in fire frequency. Our results also indicate that fires that did not leave visible fire scars on the tree stem may be identified based on the date of growth release revealed from dendrochronology.

climate warming -- bioclimatic models -- major conifer ranges -- Central Siberia

Аннотация: Regional studies have shown that winters warmed 2-3 degrees C while summers warmed 1-2 degrees C during the1960-2010 period in central Siberia. Increased warming predicted from general circulation models (GCMs) by the end of the century is expected to impact Siberian vegetation. Our goal is to evaluate the consequences of climate warming on vegetation, forests, and forest-forming tree species in central Siberia. We use our envelope-type bioclimatic models of the Siberian forests and major tree conifer species based on three climatic indices which characterise their warmth and moisture requirements and cold resistance, and on one soil factor that charactrises their tolerance to permafrost. Coupling our bioclimatic models with the climatic indices and the permafrost distributions, we predict the potential habitats of forests and forest-forming tree species in current climate conditions and also in the 2080 projected climate. In the 2080 drier climate conditions, Siberian forests are simulated to decrease significantly and shift northwards while forest-steppe and steppe would come to dominate 50 % of central Siberia. Permafrost is not predicted to thaw deep enough to sustain dark (Pinus sibirica, Abies sibirica, and Picea obovata) taiga. Dahurian larch (L. gmelinii+cajanderi), which is able to withstand permafrost, would remain the dominant tree species. Light conifers (Larix spp. and Pinus sylvestris) may gain an advantage over dark conifers in a predicted dry climate due to their resistance to water stress and wildfire. Habitats for new temperate broadleaf forests, non-existent in Siberia at present, are predicted by 2080.

Аннотация: The relative role of fire and of climate in determining canopy species composition and aboveground carbon stocks were investigated. Measurements were made along a transect extending from the dark taiga zone of central Siberia, where Picea and Abies dominate the canopy, into the Larix zone of eastern Siberia. We test the hypotheses that the change in canopy species composition is based (1) on climate-driven performance only, (2) on fire only, or (3) on fire-performance interactions. We show that the evergreen conifers Picea obovata and Abies sibirica are the natural late-successional species both in central and eastern Siberia, provided there has been no fire for an extended period of time. There are no changes in performance of the observed species along the transect. Fire appears to be the main factor explaining the dominance of Larix and of soil carbon. Of lesser influence were longitude as a proxy for climate, local hydrology and active-layer thickness. We can only partially explain fire return frequency, which is not only related to climate and land cover, but also to human behavior. Stand-replacing fires decreased from 300 to 50 yrs between the Yenisei Ridge and the upper Tunguska. Repeated non-stand-replacing surface fires eliminated the regeneration of Abies and Picea. With every 100 yrs since the last fire, the percentage of Larix decreased by 20%. Biomass of stems of single trees did not show signs of age-related decline. Relative diameter increment was 0.41 +/- 0.20% at breast height and stem volume increased linearly over time with a rate of about 0.36 t C ha(-1) yr(-1) independent of age class and species. Stand biomass reached about 130 t C ha(-1)(equivalent to about 520 m(3) ha(-1)). Individual trees of Larix were older than 600 yrs. The maximum age and biomass seemed to be limited by fungal rot of heart wood. 60% of old Larix and Picea and 30% of Pinus sibirica trees were affected by stem rot. Implications for the future role of fire and of plant diseases are discussed.

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.
