Abstract :

The article deals with the methodology of mapping the Holocene forest formations on the basis of the digital elevation model and the key climate indicators (heat and moisture). GIS methods were applied at the work. The test plot is located within the boundaries of the axial West Sayan district of mountain taiga forests, which ensures homogeneity of natural and climatic conditions. Stages of th ...

Abstract :

The Ermakovsky territory research station (53°17´–52°28´ N, 92°49´–93°20´ E) has served as a long-term site for studies of mountain forest ecosystem structure and its dynamics during the last 50 years. The most interesting results of study in 2000–2014 are presented in the paper concerning biodiversity and forest succession in primary and secondary forest types forming the chern forest format ...

Abstract :

The Illumina HiSeq2000 DNA sequencer was used for nuclear DNA sequencing in larch (Larix sibirica Ledeb.) and Siberian stone pine (Pinus sibirica Du Tour.). As a result, it was generated 2 906 977 265 high quality paired-end nucleotide sequences (reads) and 576 Gbp for Siberian larch, that corresponds to 48X coverage of the larch genome (12.03 Gbp), and 3 427 566 813 reads and 679 Gbp for Sibe ...

Abstract :

Data on genetic diversity and differentiation degree of number of Siberian spruce (Picea obovata Ledeb.) populations from different parts of its geographic range was obtained based on variability analysis of nuclear and chloroplast DNA isoenzyme loci and microsatellite loci. Study included Siberian spruce isolated populations located on Olkhon island (Baikal lake), in Bogd-Uul natural reserve ...

Abstract :

Fire risk in major forest types and concomitant vegetation complexes across different altitudinal belts of the Baikal region has been analyzed. High fire risk in woodlands is determined by domination of light needle coniferous stands in their structure and specific climate with continuous spring-summer droughts. Thus, the risk of landscape wildfires is high. The most drastic situations occur i ...

Abstract :

Allozyme polymorphism of Siberian stone pine (Pinus sibirica Du Tour) has been studied in 14 artificial stands in the South Urals and Bashkir Cis-Urals on the basis of a 7 gene-enzyme system analysis. The following values of genetic diversity are determined: mean number of alleles per locus (A) constitutes 1.69±0.08; portion of polymorphic loci (P99) – 50.0%; the average expected heterozygosit ...

Abstract :

Nutrient medium composition and cultivation conditions of Scots pine (Pinus sylvestris L.) callus effect on its cells morphology, their differentiation and lignification (LC) degree was studied. Callus cells morphological characteristics, lignin content and macromolecular structure considerably vary in dependence of different factors. The increase in the duration of callus cultivation from 21 ...

Abstract :

The paper is devoted to the effects of various fire intensities on components of pine forests. Based on experiments of forest fire modeling conducted in 2002-2003 for the first time in Siberia, long-term monitoring of impact of various intensities fires on Scots pine stand components and post-fire succession was conducted. Significant post-fire transformation of all Scots pine stands component ...

Abstract :

In the transition zone between the forest and the steppe (in the ecotone) in the territory of the Buryatia Republic, dwarf specimens (up to 110 cm in height) of Siberian crabapple Malus baccata (L.) Borkh. were found that differ from other (up to 250 cm in height) apple trees. To determine the causes of brachysm by physiological methods, the influence of gibberellins on growth processes were s ...
