Mechanistic drivers of stem respiration: A modelling exercise across species and seasons Open
Stem respiration ( R S ) plays a crucial role in plant carbon budgets. However, its poor understanding limits our ability to model woody tissue and whole‐tree respiration. A biophysical model of stem water and carbon fluxes (TReSpire) was …

Woody tissue photosynthesis increases radial stem growth of young poplar trees under ambient atmospheric CO2 but its contribution ceases under elevated CO2 Open
Woody tissue photosynthesis (Pwt) contributes to the tree carbon (C) budget and generally stimulates radial stem growth under ambient atmospheric CO2 concentration (aCO2). Moreover, Pwt has potential to enhance tree survival under changing…

Woody tissue photosynthesis delays drought stress in <i>Populus tremula</i> trees and maintains starch reserves in branch xylem tissues Open
Summary Photosynthesis in woody tissues ( P wt ) is less sensitive to water shortage than in leaves, hence, P wt might be a crucial carbon source to alleviate drought stress. To evaluate the impact of P wt on tree drought tolerance, woody …

Biomass and nitrogen distribution ratios reveal a reduced root investment in temperate lianas vs. self-supporting plants Open
Background and Aims The reliance on external support by lianas has been hypothesized to imply a reduction in the biomass cost of stem construction and root anchorage, and an increased investment in leaves, relative to self-supporting plant…

Species-specific responses of growth and biomass distribution to trellis availability in three temperate lianas Open
In some lianas the use of trellis modifies within-plant biomass allocation and stimulates growth, however in other species trellis use may negatively affect growth indicating a cost associated with climbing. In order to improve access to l…

Does climate-related in situ variability of Scots pine (Pinus sylvestris L.) needles have a genetic basis? Evidence from common garden experiments Open
The correlations of phenotypic traits with environmental drivers suggest that variability of these traits is a result of natural selection, especially if such trait correlations are based on genetic variability. We hypothesized that in sit…
