-gporocarps of hypogeous mycorrhizal fungi (truffles) are the major food of northern flying squirrels (Gluucomys satinus). The two subspecies of northern flying squirrels that occur in the southern Appalachians, G. s. colmatus and G. s. fuscus, are endangered species which are primarily found in the ecotone between high-elevation spruce-fir and northern hardwood forests. Our objective was to de...

Research Highlights: Management of the risks forests are exposed to is based on dynamics composition and structure stands forest. Background Objectives: This study aimed document forest in Romanian Carpathians over last five decades, as well estimate forecast near future (i.e., 2070). Materials Methods: The obtained results were long-term monitoring analysis species structures research areas (o...

The paper presents the results of a study on tree regeneration of forest stands in the Černý důl Nature Reserve, which is situated in the Orlické hory Mountains Protected Landscape area in the Czech Republic. Research was conducted in a spruce-beech stand with an admixture of silver fir, sycamore maple and rowan on two comparative permanent research plots (PRPs) (PRP 1—fenced enclosure and PRP ...

Research Highlights: In mixed stands, competitive and supportive relationships occur between trees, illustrated by their dendrometric characteristics. Background Objectives: We investigated the effect of species composition on growth yield in beech–coniferous stands Romanian Carpathians. Materials Methods: selected sites with similar trophicity levels, as determined site mapping method. Under s...

this study was designed to investigate the structural characteristics of beech forests in the middle stage of ecological succession. in order to this purpose undisturbed beech stands in kheyroud forest had chosen and three one hectare sampling plot laid out. all of tree species measured with full callipering method and diameter and height of trees were recorded. natural regeneration within one ...

During the last meeting in Karlsruhe the authors presented a paper [1] providing background information about the determination of the characteristic bending strength of beech glulam. A design proposal was derived to calculate the characteristic bending strength depending on the characteristic tensile strength of the lamellae and the characteristic finger joint bending strength. It was experime...

Abstract The character of pure or mixed forest canopies and their litterfalls contribute to different forest-floor properties. These organic layers also subjacent topsoil were studied at three study sites covered by treatments such as beech–spruce, beech–fir, spruce–fir two monospecific beech spruce treatments. age the stands ranged from 11 15 years when sampled. All used meadows afforested; th...
