Resumen :

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 ...

Resumen :

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 ...

Resumen :

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 ...

Resumen :

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 ...
