Freshly cut beech deadwood was enriched in the canopy and on the ground in three cultural landscapes in Germany (Swabian Alb, Hainich-Dün, Schorfheide-Chorin) in order to analyse the diversity, distribution and interaction of wood-inhabiting fungi and beetles. After two years of wood decay 83 MOTUs (Molecular Operational Taxonomic Units) from 28 wood samples were identified. Flight Interception...

Airborne fungi were collected over a one year period at 2-month intervals at 2 sawmills in Croatia (SM 1 and SM 2) processing mainly beech wood and oak wood. A questionnaire concerning respiratory symptoms and skin prick test (SPT) with common inhalatory allergens and moulds Cladosporium herbarum, Alternaria alternata, Aspergillus niger, Penicillium notatum, and Rhizopus nigricans were performe...

American beech (Fagus grandifolia), now a centerpiece species of the eastern deciduous forest, has had a continually changing historical biogeography. This paper reviews the paleoecology, the presettlement occurrence, the modern range, and the current abundance pattern of beech. It synthesizes these four databases into maps representing the distribution and abundance of beech at specific period...

The wood of five European species: black poplar (Populus nigra L.), beech (Fagus sylvatica ash (Fraxinus excelsior oak (Quercus robur and Scots pine (Pinus sylvestris L.) was subjected to thermal modification in nitrogen atmosphere at 190 °C during 6 h. Native modified varnished oiled industrial conditions. Thermally (TM) characterized by a greater absorption varnish oil when applying the first...

Temporal and spatial characteristics of microwave dielectric properties and water status of several forest species were investigated during the 1990 and 1991 growing seasons as part of the NASA FED MAC. Data presented were acquired from Durham, New Hampshire (white pine, eastern hemlock, and American beech), and Howland, Maine (eastern hemlock and red spruce). Dielectric properties of trunk woo...

Ionic liquids represent a class of highly tunable organic compounds responsible for many applications in the domain wood-based materials. It has often been emphasized that use ionic derives from their high affinity lignocellulose and good penetration ability into wood structures. This paper discusses sorption different types 1-alkyl-3-methylimidazolium with lateral alkyl chains, ranging ethyl t...

BACKGROUND Beech and oak pollen are potential allergen sources with a world-wide distribution. OBJECTIVE We aimed to characterize the allergen profile of beech and oak pollen and to study cross-reactivities with birch and grass pollen allergens. METHODS Sera from tree pollen-allergic patients with evidence for beech and oak pollen sensitization from Basel, Switzerland, (n=23) and sera from ...
