Contributions of bark and tension wood and role of the G-layer lignification in the gravitropic movements of 21 tropical tree species

Gravitropic movements in angiosperm woody stems are achieved through the action of bark and/or wood motor, depending on the bark and wood fibre anatomy (with trellis structure or not; with G-layers or not). Bark motor is as

Proteomic analysis of black poplar (Populus nigra L.) seed storability

Adequate storability of black poplar ( Populus nigra L.) seeds at temperatures below 0 °C was associated with preservation of proteins of energy and carbohydrate metabolism, protein turnover, and proteins maintaining long-term stability of dehydrated tissue. Context

Impact of deadwood decomposition on soil organic carbon sequestration in Estonian and Polish forests

The deadwood of different tree species with different decomposition rates affects soil organic carbon sequestration in Estonian and Polish forests. In warmer conditions (Poland), the deadwood decomposition process had a higher rate than in cooler Estonian forests.

Predicting growth and habitat responses of Ginkgo biloba L. to climate change

We developed a climatic response function using 20-year tree height observed from 45 Ginkgo biloba plantations in China and used it to predict the growth and habitat responses to anticipated climate change. We projected northward and upward

Variation in carbon concentrations and allocations among Larix olgensis populations growing in three field environments

Variation in carbon concentration among Larix olgensis A. Henry provenances and tree tissues was significant, suggesting importance of such variation to carbon stock calculation. Provenance variation in carbon allocation was only significant in allocations to some tissues,

Polyculture affects biomass production of component species but not total standing biomass and soil carbon stocks in a temperate forest plantation

Over-yielding of stand biomass did not occur in a tree polyculture comprised of Betula pendula, Alnus glutinosa and Fagus sylvatica selected for contrasting traits. This was due to antagonistic interactions between the component species. Fine root dynamics

The utility of terrestrial photogrammetry for assessment of tree volume and taper in boreal mixedwood forests

This study showed that digital terrestrial photogrammetry is able to produce accurate estimates of stem volume and diameter across a range of species and tree sizes that showed strong correspondence when compared with traditional inventory techniques. This

The conifer-curve: fast prediction of hydraulic conductivity loss and vulnerability to cavitation

The relationship between relative water loss (RWL) and hydraulic conductivity loss (PLC) in sapwood is robust across conifer species. We provide an empirical model (conifer-curve) for predicting PLC from simple RWL measurements. The approach is regarded as

Harmonised projections of future forest resources in Europe

A dataset of forest resource projections in 23 European countries to 2040 has been prepared for forest-related policy analysis and decision-making. Due to applying harmonised definitions, while maintaining country-specific forestry practices, the projections should be usable from

Using synthetic semiochemicals to train canines to detect bark beetle–infested trees

The dog detection allows timely removal by sanitation logging of first beetle-attacked trees before offspring emergence, preventing local beetle increases. Detection dogs rapidly learned responding to synthetic bark beetle pheromone components, with known chemical titres, allowing search
