Whole-tree O3 uptake was exemplified for Picea abies, Fagus sylvatica and Larix decidua in stands at high and low altitude and contrasting water availability through sap flow measurement in tree trunks, intrinsically accounting for drought and boundary layer effects on O3 flux. O3 uptake of evergreen spruce per unit foliage area was enhanced by 100% at high relative to low elevation, whereas de...

Beech (Fagus orientalis Lipsky) forests in Iran are one of the most important sources hardwood species used for lumber, furniture, and interior object design due to its hardness, wear resistance, strength, excellent bending capabilities. Furthermore, is third country walnut wood production after China United States. Therefore, this study, we compared specific mechanical properties between beech...

The aim of this study was to reconstruct the vegetation changes, fire history and local landscape dynamics central Croatia (the western part south-eastern Europe) from 9800 cal yr BP beginning Common Era. Pollen, non-pollen palynomorphs charcoal were analysed for first time in aforementioned area by modern palynological methods. Three different assemblage (sub)zones identified: “Pinus-Fagus-Que...

Natural regeneration of tree species is sensitive to silvicultural interventions. This study aimed investigate the effects different cutting intensities and local topographic soil conditions on composition stable carbon (δ13C) oxygen (δ18O) isotopes in wood young beech (Fagus sylvatica L.) trees. Beech saplings layer were sampled summer 2018 at three sites Dinaric fir-beech forests karst area S...

The aim of this work was to verify the behavior hybrid hardwood glue-laminated beams and possibility replacing Norway spruce (Picea abies) construction elements, especially in roof ceiling structures. samples were six lamellae homogeneous beech (Fagus sylvatica) six-lamellae beech-poplar sylvatica–Poplar spp.) beams; each beam had a cross-section 60 × 120 mm glued with polyurethane adhesive. lo...

We present a new method for the classification of beech (Fagus sylvatica L.) forest plots based on discriminant and frequency analysis. This can be used as tool to allow experts stratify forests in simple precise way. The is analysis with cross-validation 13 variables measured 142 from 2005 Second National Forest Inventory 63 an inventory installed specific locations together qualifying variabl...

To determine the effects of ozone (O3) on the canopy carbon budget, we investigated photosynthesis and respiration of leaves of Siebold's beech saplings under free air O3 exposure (60 nmol mol(-1), during daytime) in relation to the within-canopy light gradient; we then calculated the canopy-level photosynthetic carbon gain (PCG) and respiratory carbon loss (RCL) using a canopy photosynthesis m...
