Intra- and interprovenance variations in leaf morphometric traits in European beech (Fagus sylvatica L.) [PDF]

open access: yesArchives of Biological Sciences, 2016
European beech (Fagus sylvatica L.) is one of the most important tree species in Europe. Due to substantial genetic diversity and phenotypic plasticity, beech has successfully adapted to different environments within its natural range ...

Dynamics of common wasps in New Zealand beech forests: a model with density dependence and weather [PDF]

open access: yesJournal of Animal Ecology, 2002
Summary Nest densities of the common wasp ( Vespula vulgaris (L.)) were monitored at six sites for 13 years in the honeydew‐rich southern beech ( Nothofagus spp.) forests of New Zealand's South Island. Densities of wasp nests were among the highest in the world, up to 30 ha −1 , and at any one site varied ...

The Impact of the Log-Sawing Patterns on the Quantitative and Qualitative Yield of Beech Timber (Fagus sylvatica L.)

open access: yesApplied Sciences, 2023
The cost of raw materials has a major role in the wood industry. From this point of view, it is necessary to pay attention to the correct log-sawing pattern, which will optimize the sawing process and increase the quantity and quality of the material as ...

Latent infection of Biscogniauxia nummularia in Fagus sylvatica: a possible bioindicator of beech health conditions

open access: yesiForest - Biogeosciences and Forestry, 2016
Biscogniauxia nummularia is a xylariaceous fungus known as a common endophyte of European beech, living in plant tissues without development of symptoms, or even inducing strip-cankers and wood decay on trees stressed by drought.

The first reaction of soil mite fauna (Acari, Mesostigmata) caused by conversion of Norway spruce stand in the Szklarska Poręba Forest District

open access: yesJournal of Forest Science, 2009
To observe the first reaction of Mesostigmata mites for conversion of even aged spruce stands under conversion with common beech and silver fir, four pairs of experimental plots directly neighbouring each other were examined.

A Sustainable Bio‐Based Epoxy Thermoset as a High‐Performance Alternative to BPA‐Based Resins

open access: yesAdvanced Science, EarlyView.
A rigid–flexible bio‐based epoxy network integrates soybean oil, lignin, and maleic anhydride to overcome the strength–toughness–sustainability trade‐off of conventional BPA epoxy. The thermoset delivers excellent performance as both a structural adhesive and a matrix for glass‐fabric composites, while enabling pH‐responsive degradation, environmental ...

Sustainable Carbon Fibers Enable Stable Long‐Term Lithium Metal Deposition for Prospective Zero‐Excess Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents lightweight, lignin‐derived carbon fiber current collectors that enable controlled lithium deposition. Structural defects and intermediate‐sized pores stabilize pre‐nucleation quasi‐metallic lithium clusters, promoting uniform lithium plating and stripping.

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
