To find out the wood species used in national structures late Joseon Dynasty, 11 volumes of Yeonggeon-Uigwes were reviewed. It was confirmed that mainly for repair and restoration palaces, shrines, fortresses. In 17th to 20th centuries, specified have revealed either hardwood or softwood. As species, Juglans mandshurica, Zelkova serrata, Fraxinus rhynchophylla, Betula schmidtii, Paulownia corea...

We resurveyed the under- and overstory species composition of 94 upland forest stands in southern Wisconsin in 2002-2004 to assess shifts in canopy and understory richness, composition, and heterogeneity relative to the original surveys in 1949-1950. The canopy has shifted from mostly oaks (Quercus spp.) toward more mesic and shade-tolerant trees (primarily Acer spp.). Oak-dominated early-succe...

137 Biochar (BC) was evaluated for nitrogen (N) and phosphorus (P) removal from aqueous solution to quantify its nutrient pollution mitigation potential in agroecosystems. Sorption isotherms were prepared for solutions of ammonium (NH4 +), nitrate (NO3 -), and phosphate (PO4–P) using BC of corn (Zea mays L.) and oak (Quercus spp.) feedstock, each pyrolyzed at 350 and 550°C highest treatment tem...

Abstract Key message A vegetation analysis revealed the extent of recolonization by native a 25-year-old Cupressus spp. plantation in northern Iran. young indigenous Quercus-Carpinus community replaced conifers low-slope areas with deeper, heavier, and more fertile soils. Context Reforestation degraded or clear-cut-harvested lands can modify site conditions, facilitating succession reestablishi...

Quercus cerris is an important oak species extended in large areas of Eastern Europe and Minor Asia that has a thick bark which is not utilized at all. The sorption performance of cork from Quercus cerris bark with four polycyclic aromatic hydrocarbons (PAHs) (acenaphthene, fluorene, phenanthrene, and anthracene) was investigated. Quercus cerris cork was characterized for elemental analysis, ac...

Drought entails important effects on tree physiology, which may result in short- to long-term radial growth decreases. While the majority of studies have focused on annual drought-related variability of growth, relatively little is known about sustained growth decreases following drought years. We apply a statistical framework to identify climatic factors that induce abrupt growth decreases and...
