    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.

Аннотация: Despite of the active studying somatic embryogenesis in gymnosperms this technique still remains problematic for coniferous species growing in Siberia. The aim of this study is the development of efficient biotechnological protocols of Larix species (L. sibirica, L. gmelini, L. sukaczewii), Pinus Sibirica in somatic embryogenesis and their optimization using cytoembryological control. The sussess of the somatic embryogenesis is due to the stage of explant development, medium components, hormonal regulation and tree genotypes.

Аннотация: A model of the population dynamics of insects has been developed, which takes into account the food consumption by insects and the reaction of food plants to the damage. Equations have been derived that describe the relationship between the coefficient of insect reproduction, the weight of females, the energetic effectiveness of the food consumption by insects, and the reaction of food plants. The scenarios of population outbreaks have been analyzed as a function of the weight of females in the stable state. The results of modeling have been compared with the data of natural observations.

Аннотация: The authors analyze spatial distribution and survival of populations of poplar moth Litchcolletis populifoliella Tr on its feeding plant - balsam poplar Populus balsamifera Imago of the moth glue its eggs on the leaves thus determining the future location of their offspring on the host plant Spatial distribution of eggs on leaf surface and distribution of leaves according egg numbers are not random On the short distance from each egg the average number of eggs is less, than it should be in case of random distribution While this distance increases up to some particular value the occurrence of eggs is higher than random Thus, the eggs of moth are located by groups on the leaf surface Within each group eggs are situated not very close to each other, this allowing larvae to lower competition for common resource It is suggested that on the same feeding plant individuals have different interactions competition, caused by limited quantity of resource and cooperation that is necessary to resist leaf defensive (antibiosis) reaction.

    Thinnings in design of siberian pine forests in dark taiga of western sayan
/ M. E. Konovalova, D. M. Danilina, D. I. Nazimova // Russ. J. For. Sci. - 2017. - Is. 5. - С. 16-27, DOI 10.7868/S0024114817050023 . - ISSN 0024-1148
Аннотация: We tested management practices to develop Siberian pine forests at monitoring plots of the Institute of forest in Ermakovo (Western Sayan). Siberian pine forests developed from mixed young stands. They grew on clearcuts in tall grasses-ferns fir and Siberian pine forests in submontane dark taiga domain. The dynamics of all storeys and structural elements of the communities were studied and compared to the control at two 2500 m2 plots from 1966 to 2014. Here we consider the case of admitting light to the Siberian pine undergrowth at first thinning. This practice has proved itself optimal for further management recommendations. Siberian pine trees have gained competitive advantage in aspen or fir forests after the first thinning for a short period before the dominant species or birch started to regenerate actively. Repeated thinning supported sustainable dominance of Siberian pine in the stands. Our experiment showed that highly productive Siberian pine forests in the unique environment could be formed for 50 years rather than more than 200 years of natural succession. The managed stands and intact Siberian pine forests in dark taiga have similar normality of 0.4-0.6 and storages of 182 m3 ha-1 at the age of 70-80 years and 270 m3 ha-1 at the age of 80-90 years. However the managed stands yield more nuts (about 300 kg ha-1) at the age of 70-90 years. Thinning supported the growth of the stand with dominant Siberian pine, and phytocoenotic structure similar to intact Siberian pine forests of dark taiga having high diversity, which supports regeneration of Siberian pine. © 2017, Izdatel'stvo Nauka.

Аннотация: We have tested management practices at monitoring plots of the Institute of Forest, Russian Academy of Sciences, in Ermakovo station (Western Sayan) to develop Siberian pine forests (Pinus sibirica Du Tour) from young coniferous-deciduous forests that were formed in the place of clearcuttings in tall-grass-fern fir and Siberian pine forests in the low-mountain dark Chern zone. The dynamics of all layers and structural elements of the communities were studied from 1966 to 2014 at two experimental monitoring plots (each with an area of 2500 m(2)) and compared to the control. The article considers the case of admitting the complete lighting of Siberian pine undergrowth at first thinning. This practice proved to be optimal for further forest-management recommendations. Siberian pine gained competitive advantages over aspen or fir after the first thinning for a short period until the dominant species (aspen, birch, or fir) started to actively regenerate. Repeated thinning made Siberian pine steadily dominant in stands. Our experiment has shown that highly productive Siberian pine forests can be formed for 50 years under the unique natural and climate conditions of the low-mountain Chern zone of the Western Sayan, while the natural course of succession could not yield this result even after 200 or more years. These forests are comparable to indigenous dark Siberian pine forests with respect to their density (0.4-0.6) and wood stock (182 m(3)/ha at the age of 70-80 years and 270 m(3)/ha at the age of 80-90 years); however, the managed stands yield many more nuts (about 300 kg/ha) at the age of 70-90 years. Thinning induced the growth of a stand dominated by Siberian pine, as well as the formation of a phytocenotic structure similar to indigenous dark Siberian pine forests, i.e., a structure with a high diversity.

    Response of four tree species to changing climate in a Moisture-Limited Area of South Siberia
/ E. A. Babushkina [et al.] // Forests. - 2019. - Vol. 10, Is. 11. - Ст. 999, DOI 10.3390/f10110999 . - ISSN 1999-4907
Аннотация: The response of vegetation to climate change is of special interest in regions where rapid warming is coupled with moisture deficit. This raises the question of the limits in plants' acclimation ability and the consequent shifts of the vegetation cover. Radial growth dynamics and climatic response were studied in Scots pine (Pinus sylvestris L.), Siberian larch (Larix sibirica Ledeb.), and silver birch (Betula pendula Roth.) in the forest-steppe, and for Siberian elm (Ulmus pumila L.) in the steppe of South Siberia, as indicators of vegetation state and dynamics. Climate-growth relationships were analyzed by the following two approaches: (1) correlations between tree-ring width chronologies and short-term moving climatic series, and (2) optimization of the parameters of the Vaganov-Shashkin tree growth simulation model to assess the ecophysiological characteristics of species. Regional warming was accompanied by a slower increase of the average moisture deficit, but not in the severity of droughts. In the forest-steppe, the trees demonstrated stable growth and responded to the May-July climate. In the steppe, elm was limited by moisture deficit in May-beginning of June, during the peak water deficit. The forest-steppe stands were apparently acclimated successfully to the current climatic trends. It seems that elm was able to counter the water deficit, likely through its capacity to regulate transpiration by the stomatal morphology and xylem structure, using most of the stem as a water reservoir; earlier onset; and high growth rate, and these physiological traits may provide advantages to this species, leading to its expansion in steppes. © 2019 by the authors.

Аннотация: Soils store much more carbon (C) than all terrestrial plants and the Earth's atmosphere together, and the C exchange between soils and atmosphere largely influences the CO2 contents in the atmosphere. While converting native ecosystems into agricultural land in the past caused a huge historical release of C into the atmosphere, an optimization of the management of agricultural soils offers the possibility of restoring parts of the previously lost C in the soil. However, in this respect, interrelationships of land use and soil management with climate change must be considered. In this chapter, land use and climatic effects on soil organic carbon (SOC) stocks in the large western Siberian grasslands will be evaluated and scenarios of future development of SOC storage will be given. A combination of soil analysis along a climatic gradient from the forest steppe to the dry steppe and a modelling approach with the Lund-Potsdam-Jena managed Land (LPJmL) model revealed, that since their cultivation soils of the Kulunda steppe lost about 20-35% of their organic C. Surprisingly, not only particulate organic C was affected but likewise also organic C located within mineral-organic associations was lost, and the proportion of the lost C is independent from the climatic conditions. Parts of this lost organic C can be restored by abandoning arable land. However, due to political and economic constraints, this does not seem to be likely. Minimum or zero tillage may provide an option to increase the organic C storage in western Siberian steppe soils, but the potential effect may be limited. The LPJmL model simulates a continuing climate-change driven C loss from soil, which corroborates results of soil analysis along the climatic gradient. The management of SOC stock has to be evaluated also for its effect on soil erosion, water deficiency and nutrient shortage.
