INFLUENCE OF MACROSTRUCTURE ON THE DENSITY OF OAK WOOD

open access: yesForestry Engineering Journal, 2021
An individual process of staining of each trunk occurs as a result of the long-term presence of wood in the river soil without oxygen access. It consists in changing the structure and chemical composition of the wood. There are industrial reserves of this wood on the territory of the Russian Federation, in the floodplains of a number of rivers. One of

Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

USE OF OAK ALTERNATIVE PRODUCTS IN VINIFICATION

open access: yesHarčova Nauka ì Tehnologìâ
Traditionally, the best wines are aged in oak barrels. It is generally accepted that the quality of wines and spirits depends on their aging in contact with oak wood. The selection of oak wood and its maturation are mandatory stages of barrel production.

Environmentally induced dynamics between intraindividual variation and trait means across vegetative, phenological, and floral traits

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Intraindividual variation in reiterated structures (e.g., leaves) represents an important dimension of phenotypic variation that contributes to functional diversity and the dynamics of ecological communities. It can be expressed differently across plant traits, but how environmental drivers affect intraindividual variation in different

Comparison of the bond strength of oak (Quercus L.) and beech (Fagus sylvatica L.) wood glued with different adhesives considering various hydrothermal exposures

open access: yesJournal of Forest Science, 2015
The investigation of the hydrothermal exposure effect on the glue-line strength is obvious when outdoor application of wood products is in option. In our research the bonding quality of oak (Quercus L.) and beech (Fagus sylvatica L.) wood was tested in ...

Evaluation of Wood Pretreatments on Oak and Cedar [PDF]

open access: yesRadiocarbon, 1997
In a separate study, we conducted a series of high-precision radiocarbon measurements using wood from Britain and New Zealand to investigate interhemispheric offsets and possible temporal variations. To minimize variability associated with different species, the pretreatment of the oak (Quercus patraea) and cedar (Librocedrus bidwilli) was to α ...
