Many of the Loch Tay crannogs were built in the Early Iron Age and so calibration of the radiocarbon ages produces very broad calendar age ranges due to the well-documented Hallstatt plateau in the calibration curve. However, the large oak timbers that were used in the construction of some of the crannogs potentially provide a means of improving the precision of the dating through subdividing t...

Historical reference conditions provide important context for creating ecological restoration and management plans. The U.S. 19th Century Public Land Survey (PLS) records provide extensive ecological information for constructing such reference conditions. We used PLS records to reconstruct pre-Euro-American tree species cover class and vegetation structure types for the Midwest Driftless Area, ...

The composition and temporal variation in species recruitment were examined in relation to annual dendrochronological data to determine the historical development and successional history of an old-growth mixed-oak (Quercus) forest in northern Virginia, USA. A ridge site in the upland Piedmont, along the Potomac River, was used to survey the old-growth forest, which is dominated by Quercus alba...

Within-stem variation in the mechanical properties of Portuguese oak wood was analysed, considering different locations (three sites centre and north Portugal—Site 1, Site 2, 3) positions within tree (two distances to pith—P1, P2). The study comprised compression parallel grain, bending strength modulus elasticity. Ultimately, this aims at assuring building a body knowledge on technological qua...

Cupriavidus basilensis 4G11 was isolated from groundwater at the Oak Ridge Field Research Center (FRC) site. Here, we report the complete genome sequence and annotation of Cupriavidus basilensis 4G11. The genome contains 8,421,483 bp, 7,661 predicted protein-coding genes, and a total GC content of 64.4%.

Forest structural diversity is related to stability, biodiversity, adaptability and resilience, as well productivity of forest ecosystems. In this study, we characterized the diverse type groups in southeastern Outer Coastal Plains Mixed Province United States. We utilized data from 13,658 Inventory Analysis (FIA) plots across region classified them on basis group (i.e., longleaf-slash pine, lo...

Oak and birch trees belong to Fagales order. Specific IgE to pollen allergens of both trees are frequently found in Korea pollinosis patients. Oak trees which comprise 40% of forest area are common in Korea. However, birch trees are sparse. We compared the allergenicity of pollen extracts of white oak, sawtooth and Mongolian oaks which are prevalent species in Korea, with the pollen extract of ...

During barrel maturation, the volatile compounds extracted from oak wood can contribute to a wine’s overall aroma and flavour, enhancing its character and complexity. However, barrels have a finite pool of extractable material and the amounts of oak derived volatile compounds available for extraction diminish over time. As a consequence, barrels are typically decommissioned after five to six ye...

ABSTRACT During 2001 to 2003, the transmission biology of Phytophthora ramorum, the causal agent of sudden oak death, was studied in mixedevergreen forest, a common forest type in northern, coastal California. Investigation of the sources of spore production focused on coast live oak (Quercus agrifolia) and bay laurel (Umbellularia californica), dominant hosts that comprised 39.7 and 46.2% of t...
