Transpiration and stomatal conductance in deciduous needleleaf boreal forests of northern Siberia can be highly sensitive to water stress, permafrost thaw, and atmospheric dryness. Additionally, north-eastern Siberian boreal forests are fire-driven, and larch (Larix spp.) are the sole tree species. ...

Droughts influenced the effects of increasing intrinsic water use efficiency (iWUE) on tree growth. Yet, litter is known on stand density- and age-related relationship among droughts, iWUE, and tree growth in plantations. We used tree-ring growth and δ¹³C data from three dominated species (larch,...

Indirect arguments in favor of the assumption «the drying of the tree tops in the stems of Gmelin larch (Larix gmelinii (Rupr.) Rupr.), growing on permafrost soil of the northern slope is due to the discrepancy between the structure of the water transport system in the stem and physiologically...

Phaeolus schweinitzii (Fr.) Pat. was originally described in Europe and is considered a common forest pathogen on conifers in the Northern Hemisphere. Our molecular phylogeny based on samples from China, Europe, and North America confirms that P. schweinitzii is a species complex, including six...

Significant air temperature and precipitation changes have occurred since the 2000s in vulnerable Siberian subarctic regions and urged updates of available chronologies towards the third millennium. It is important to better understand recent climatic changes compared to the past decades, centuries ...

Deciduous larch species could be an alternative to evergreen conifers in reforestation, but little is known about drought sensitivity of their saplings. The effect of an experimental drought on hydraulics and quantitative wood anatomy was tested on saplings of European larch (EL, Larix decidua),...

Pollen productivity is a critical parameter in the interpretation of pollen-vegetation relationships, and in the quantitative reconstructions of past vegetation from fossil pollen records. One-year monitoring records were collected for 143 pollen traps in various parts of northern China, together...

A comprehensive assessment of the tree growth/climate relationship was undertaken to better understand the potential impacts of climate change on the growth dynamics of four widespread and common boreal tree species, namely jack pine (Pinus banksiana), black spruce (Picea mariana), eastern larch (...

Intrinsic water-use efficiency (iWUE) is the ratio of the photosynthetic assimilation rate to stomatal conductance and is tightly linked with tree growth and mortality. Increasing atmospheric nitrogen (N) deposition has been recognized to have a profound influence on ecosystem functioning,...

Clonal propagation of conifers using somatic embryogenesis is essential for the selection of tree species, and for the implementation of afforestation and reforestation. In combination with cryopreservation, somatic embryogenesis creates the basis for the development of economically valuable lines...
