Anticipated changes in climate and research findings on the drought sensitivity of beech have triggered controversial discussions about the future of European beech. We investigated the growth response of beech on the treeand stand-level in mature stands to three different thinning intensities (no thinning, strong thinning, very strong thinning) on a northeastand southwest-facing slope in South...
Bark-based biorefineries are estimated to become a trending topic in the coming years, particularly with their adsorbent applications and antioxidant production. While potential benefits of bark-based well-recognized, it is not known how develop biorefinery considering different unit operations end products. The characterization screening barks for chemical composition initial step development,...
resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. to observe how differences in forest management affect the genetic structure of fagus orientalis lipsky (oriental beech), we evaluated thirteen beech sites across hyrcanian forests, based on six microsatellite loci. significant di...
Specialist herbivores are thought to often enhance or maintain plant diversity within ecosystems, because they prevent their host species from becoming competitively dominant. In contrast, specialist herbivores are not generally expected to have negative impacts on non-hosts. However, we describe a cascade of indirect interactions whereby a specialist sooty mold (Scorias spongiosa) colonizes th...
European beech (Fagus sylvatica L., hereafter beech), one of the major native tree species in Europe, is known to be drought sensitive. Thus, the identification of critical thresholds of drought impact intensity and duration are of high interest for assessing the adaptive potential of European beech to climate change in its native range. In a common garden experiment with one-year-old seedlings...
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...
Following a full mast production in autumn 1995 in the old growth beech forest of la Tillaie, France, cupules, live and dead yearling seedlings were counted in September 1996 in 40 plots, embracing a wide range of ecological conditions. The influence of geomorphology and forest stage on mast production and on seedling establishment and survival was studied. Maximum seedling abundance did not oc...
