SUGAR TRANSPORT AND STORAGE IN THE PHLOEM OF BETULA PENDULA ROTH VAR. PENDULA AND VAR. CARELICA

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
We have previously hypothesized that the cause of figured wood formation in Karelian birch (Betula pendula Roth var. carelica) is excessive sucrose supply to the phloem and the cambial zone.

EFFECT OF THE SOIL TEMPERATURE AND AIR TEMPERATURE ON THE GROWTH OF SILVER BIRCH SEEDLINGS AND THEIR GASEOUS CO₂ EXCHANGE

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2020
Gaseous CO2 exchange and shoot growth over a growing season were studied in 3‑yearold seedlings of silver birch (Betula pendula Roth) growing in 10‑litre pots with different soil temperatures.

Provenance Variation in Functional Traits of European Forest Trees: Meta‐Analysis Reveals Effects of Taxa and Age Despite Critical Research Gaps

Ecology and Evolution, Volume 15, Issue 8, August 2025.
This meta‐analysis on intraspecific variation in European trees studied the frequency of provenance variation, provenance–environment interaction, clinal variation along the climate of origin or transfer distance. While identifying trait group specific patterns of variation, research gaps have been identified in terms of age and geographical ...

Forecasting probability distributions of forest yield allowing for a Bayesian approach to management planning

Silva Fennica, 2001
Probability distributions of stand basal area were predicted and evaluated in young mixed stands of Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies (L.) Karst.) and birch (Betula pendula Roth and Betula pubescens Ehrh.) in Sweden.

Individual tree extraction through 3D promptable segmentation networks

Methods in Ecology and Evolution, Volume 16, Issue 8, Page 1749-1762, August 2025.
Abstract The extraction of individual trees from three‐dimensional (3D) forest point clouds plays a pivotal role in forest inventory updates, forest resource management, growth and yield estimation of trees, etc. Existing end‐to‐end deep learning‐based methods for extracting individual trees typically rely on extracting instance‐sensitive features and ...

Ecological aspects of dispersion of gall mites in the vertical profile of the birch crown

Journal of Forest Science, 2004
In stands of birch Betula pendula Roth in the eastern Krušné hory Mts. the occurrence of the gall mites Acalitus rudis Canestrini and Phyllocoptes lionotus Nalepa was studied in terms of their dispersion in the tree crown. Statistical analyses of data on

Evaluation of silver birch diameter increment model based on data of the Czech National Forest Inventory

Journal of Forest Science, 2020
In the Czech Republic, the silver birch (Betula pendula Roth.) is considered as a pioneer and a soil preparing tree species. It occurs mainly on clearcutting areas after disturbances.
