Characterization of the Volatile Compounds of the Hardwood Portion of Betula papyrifera Marshall From Quebec, Canada. [PDF]

Chem Biodivers
The volatile profile of Betula papyrifera hardwood has been characterized using both hydrodistillation and HS‐SPME coupled with GC‐MS/FID. Hydrodistillation yields a fatty acid‐rich essential oil, while HS‐SPME reveals a broader range of low‐molecular‐weight volatiles, including aromatics and terpenoids.

Elevated atmospheric CO2 and humidity delay leaf fall in Betula pendula, but not in Alnus glutinosa or Populus tremula × tremuloides [PDF]

, 2014
Context: Anthropogenic activity has increased the level of atmospheric CO2, which is driving an increase of global temperatures and associated changes in precipitation patterns.

Feeding of the willow leaf beetle Lochmaea capreae L. (Coleoptera, Chrysomelidae) on leaves of birch (Betula pendula Roth) contaminated by heavy metals

Journal of Forest Science, 2004
The effect of contamination of birch (Betula pendula Roth) leaves with heavy metals on the feeding of imagoes of the willow leaf beetle (Lochmaea capreae L.) was studied under laboratory conditions.

Does shade improve light interception efficiency? A comparison among seedlings from shade-tolerant and -intolerant temperate deciduous tree species [PDF]

, 2006
• Here, we tested two hypotheses: shading increases light interception efficiency (LIE) of broadleaved tree seedlings, and shade-tolerant species exhibit larger LIEs than do shade-intolerant ones.

Conservation status of species used in the UK herbal medicine industry

PLANTS, PEOPLE, PLANET, EarlyView.
Given the ongoing biodiversity crisis, sustainable use and management of medicinal plants is critical. We assessed the conservation status, threats and conservation actions of 298 species sold by UK suppliers to medical herbalists. We found that most species used are unevaluated, representing a gap in conservation knowledge, and of those with ...

Species diversity of macrofungi on fallows in the buffer zones of the landscape parks in Łódzkie province [PDF]

, 2014
This study presents the species structure of macrofungi in different plant communities formed on fallows as a result of secondary succession. The mycological observations were carried out in 2012 and 2013 in the buffer zones of all landscape parks in the

Isozymes in Differentiating Shoot Bud Cultures of Betula pendula Roth.

Zeitschrift für Pflanzenphysiologie, 1981
Summary Shoot buds of birch cultured in vitro produced callus and differentiated plantlets. On defined White’s medium supplemented with 2 mg .1-1 each of GAl, IAA, and BAP, the explants started callusing in 2 weeks and within 4 weeks differentiated roots. After 6 weeks, the callus produced shoot buds.

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Light-modulation of bark photosynthesis in birch (Betula pendula Roth.)

Acta Biologica Slovenica, 2003
Bark photosynthesis has been shown to be an effective mechanism for stem-internal refixation of respiratory CO . In young birch trees (Betula pendula Roth.) this function is clearly modulated by the prevailing light intensity regime.

In vitro modelling of salinity stress for the selection of stress-tolerant birch lines [PDF]

E3S Web of Conferences, 2020
This paper examines the salinity stress effect in vitro culture of microshoots of 10 birch clones: Betula pendula L., B. pendula Roth var. carelica (Mercklin) Hämet-Ahti, B. pendula f. ’dalecarlica’ (L.f.) Schneid., B. pubescens Ehrh.
