How does contemporary selection shape oak phenotypes?

open access: yesEvolutionary Applications, 2020
Most existing forests are subjected to natural and human‐mediated selection pressures, which have increased due to climate change and the increasing needs of human societies for wood, fibre and fuel resources.

Visible Foliar Injury and Ecophysiological Responses to Ozone and Drought in Oak Seedlings

open access: yesPlants, 2022
To verify the responses of visible foliar injury (VFI), we exposed seedlings of three oak species for 4.5 months in an open air facility, using differing ozone (O3) and drought treatments: O3 (three levels from ambient to ×1.4 ambient), and drought ...

First Approach to the Analytical Characterization of Barrel-Aged Grape Marc Distillates Using Phenolic Compounds and Colour Parameters

open access: yesFood Technology and Biotechnology, 2014
Phenolic compounds (benzoic and cinnamic acid derivatives) were determined by high-performance liquid chromatography with multiple wavelength detector (HPLC-MWD) in grape marc distillates aged in Quercus petraea, Quercus robur and Quercus alba wooden ...

Corrigendum to “Pollen-based paleoenvironmental and paleoclimatic change at Lake Ohrid (south-eastern Europe) during the past 500 ka” published in Biogeosciences, 13, 1423–1437, 2016 [PDF]

open access: yes, 2018
In this corrigendum we report an updated pollen record from the Lake Ohrid DEEP site spanning the past 500 ka whereby we have reprocessed and re-analyzed 104 samples affected by chemical procedure problems that occurred in one palynological laboratory ...

Mycorrhizal status of several Quercus species in Romania (Quercus cerris, Q. frainetto, Q. robur) and the optimization perspective of growth conditions for in vitro propagated plants transplanted in the field [PDF]

open access: yesAnnals of Forest Research, 2011
There is an increasing interest for important tree species conservation in the context of climate change, anthropogenic pressure and invasion of alien tree species. A key factor in the survival of trees is represented by the mycorrhizal association.

Effect of artificial aging at QUV on the color of finish treated woods of Pinus sylvestris and Quercus robur

open access: yesMATEC Web of Conferences, 2018
The durability of exterior finishes on wood is not assured with the systems currently used. Thus, the objective of this study was to evaluate the color change of the finishes applied to wood, the most commercialized in Morocco, in order to find the wood ...

Medium Density Fiberboard from Quercus robur [PDF]

open access: yesJournal of Applied Sciences, 2007
The objective of this study was to investigate the suitability of oak (Ouercus robur L.) wood fibers from Turkey as a raw material for medium density fiberboard. In this study, some of the oak wood parts that are especially not suitable for other forest industries was utilized to produce fiberboards in laboratory environment.

Growth trends reveal the forest structure during Roman and Medieval times in Western Europe: a comparison between archaeological and actual oak ring series (Quercus robur and Quercus petraea) [PDF]

open access: yes, 2005
At some point in time, man has influenced nearly all forests in Western Europe. Most of the original forest cover has been converted to arable land and pastures, or has been cut for the supply of firewood and construction timber.

Repeated summer drought and re-watering during the first growing year of oak (Quercus petraea) delay autumn senescence and bud burst in the following spring [PDF]

open access: yes, 2016
Climate change predicts harsher summer droughts for mid-latitudes in Europe. To enhance our understanding of the putative impacts on forest regeneration, we studied the response of oak seedlings (Quercus petraea) to water deficit.
