In light of a significant increase in the warming trend observed in recent decades in semi-arid Mongolia, tree-ring attributes and anomalies were analysed to detect potential changes in the growth–climate relationship. In a moisture-limited environment, an increase in temperature could cause a shift in the seasonal response of trees to climate ...

Abstract Plant pests, particularly non‐native species, can have a profound impact on their host plants. Trees are the foundation of forest ecosystems and serve as important structures in agricultural landscapes and urban areas. In Sweden, forests cover around 70 % of Sweden's land area and serve as an important national resource for the economy and for

Ecological and morphological studies in the hybrid zone between Pinus sibirica and Pinus pumila
In the Baikal Region, there is no phenological isolation between Siberian stone pine (P. sibirica Du Tour) and Siberian dwarf stone pine (P. pumila (Pall.) Regel) since the timing of their 'flowering' coincides. Morphologically intermediate individuals, supposedly natural hybrids,occur not very often.

Intraspecies variation of reproductive phenology in Pinus sibirica ex situ
The analysis of the phenology of the development of female cones and male shoots in 25-year-old clones from 4 latitudinal and 4 altitudinal ecotypes of Siberian stone pine (Pinus sibirica) in the clone archive was carried out. The period from the female cone breakout to the formation of the cone with completely closed scales after pollination was 10 ...

What Are the Limits to the Growth of Boreal Fires?
Fires in East Siberia have been increasing, releasing record greenhouse gas emissions. To understand what stops these fires from spreading, we analyzed fire perimeters from satellite data covering 27,000 fires between 2012 and 2022. We found that fire weather conditions and landscape features, like roads and previous burns, play key roles in limiting ...

Structure and Function of Siberian Stone Pine Assimilation Apparatus in Central Altai Mounteens [PDF]
Needle morphology, photosynthetic pigment contents and chloroplast functional activity were measured in the four Siberian Stone pine stands: the subalpine (1570 and 1700 m asl) and the timberline (1900 and 2000 m asl).
