Teasing apart the joint effect of demography and natural selection in the birth of a contact zone

open access: yesNew Phytologist, Volume 236, Issue 5, Page 1976-1987, December 2022., 2022
Summary Vast population movements induced by recurrent climatic cycles have shaped the genetic structure of plant species. During glacial periods species were confined to low‐latitude refugia from which they recolonized higher latitudes as the climate improved.

Climate drove the fire cycle and humans influenced fire occurrence in the East European boreal forest

open access: yesEcological Monographs, Volume 92, Issue 4, November 2022., 2022
Abstract Understanding long‐term forest fire histories of boreal landscapes is instrumental for parameterizing climate–fire interactions and the role of humans affecting natural fire regimes. The eastern sections of the European boreal zone currently lack a network of annually resolved and centuries‐long forest fire histories. To fill in this knowledge

Environmental factors have a major effect in shaping the gene expression of Siberian larch in the Altai Mountains of China

open access: yesThe Plant Genome, Volume 15, Issue 3, September 2022., 2022
Abstract The differentiation of gene expression is an important link between genotype and phenotype and has important contributions to species adaptation and ecosystem evolution. As a major component of the world's forests, boreal forests play an important role in regulating the global climate, and the phenology of tree species has been and is ...

Not herbs and forbs alone: pollen‐based evidence for the presence of boreal trees and shrubs in Cis‐Baikal (Eastern Siberia) derived from the Last Glacial Maximum sediment of Lake Ochaul

open access: yesJournal of Quaternary Science, Volume 37, Issue 5, Page 868-883, July 2022., 2022
ABSTRACT A new accerator mass spectrometry (AMS)‐dated sedimentary record from Lake Ochaul (54°14′N, 106°28′E; 641 m a.s.l.) in Eastern Siberia covers the interval from ca. 27 850 to 20 400 cal a bp at ca. 180‐year resolution and contributes to a better understanding of the complex spatial vegetation pattern during the Last Glacial Maximum (LGM).

Variability of reproductive development of half-sibs of Pinus Sibirica Du Tour

open access: yesForestry Engineering Journal, 2023
Selection of Pinus sibirica Du Tour plus trees by seed productivity, breeding of half-sibs, characterized by an abundance of cones and pollen, serve as the basis for the creation of high-yielding target plantations. The aim of the research was to select families with a large percentage of early reproductive development's trees, and specimens with a lot

Changes in the Effect of Tree Stand Competition on the Pinus sibirica Undergrowth during Postfire Successions in Mid-Taiga Birch Forests of the Urals [PDF]

open access: yesE3S Web of Conferences
The effect of light and root competition of the tree stand on the growth of the Pinus sibirica Du Tour undergrowth in post-fire birch forests of different ages is investigated using the example of mid-taiga forests of the Middle Urals.

Weather Conditionality of Siberian Stone Pine (Pinus sibirica Du Tour) Seeding

open access: yesLesnoy Zhurnal (Forestry Journal), 2021
The dynamics of Siberian stone pine sexual reproduction in the South-Eastern part of the West Siberian Plain was studied by 13-year stationary observations. The stand age was 160–180 years, the average tree height was 22 m, and the average diameter of the trunk at breast height was 53 cm.

BIOCHEMICAL COMPOSITION OF VEGETATIVE EXPLANTS AND CALLUS PINUS SIBIRICA DU TOUR

open access: yeschemistry of plant raw material, 2020
The methods of sterilization of annual shoots Pinus sibirica Du Tour and the conditions for their introduction into in vitro culture were studied. Induction of callusogenesis of aseptically viable explants of P. sibirica proceeds more intensively on the modified Murasige-Skoog medium: hormonal supply of 0.4% kinetin and 0.25% 6-benzylaminopurine ...
