Fungal communities have been shown to be highly sensitive toward shifts in plant diversity and species composition in forest ecosystems. However, little is known about the impact of forest management on fungal diversity and community composition of geographically separated sites. This study examined the effects of four different forest management types on soil fungal communities. These forest m...

In this study, the application of microwave treatment for wood plasticisation and its densification for flooring system purposes is presented. Microwave plasticisation was carried out using a continuous laboratory device at a frequency of 2.45 GHz, and the testing samples made from European beech (Fagus sylvatica L.) wood were plasticised at different power modes (2 kW, 3.5 kW, and 5 kW). After...

Northern hardwoods have undergone a marked change in their dynamics, with American beech (Fagus grandifolia Ehrh.) increasing in abundance relative to sugar maple (Acer saccharum Marsh.). This study aims to better understand this sudden shift in recruitment dynamics. We performed an extensive analysis of the age structure, radial growth pattern, and release history on >700 saplings from 34 matu...

Moisture content (MC) is one of the most important factors that can affect many physical and mechanical properties of wood and veneers. MC strongly affects the final strength and durability of joints, development of surface checks in the wood and dimensional stability of the bonded assembly. In this study, plywood panels made from Alnus glutinosa (Alder), Fagus orientalis (Beech) and Picea orie...

Question: What is the effect of gap size on the seedling emergence, growth and survival of four common tree species in wooded pastures? Location: A pasture in the Jura mountains, Switzerland. Methods: Seeds were sown in a complete three-way factorial design with eight blocks in May 2003. Each block consisted of a competition treatment (four gap sizes including zero) and a mowing treatment (mown...

GRAMS T.E.E. & MATYSSEK R. 1999. Elevated CO2 counteracts the limitation by chronic ozone exposure on photosynthesis in Fagus sylvatica L.: Comparison between chlorophyll fluorescence and leaf gas exchange. Phyton (Horn, Austria) 39 (4): (31) (40). The interaction of elevated CO2 and enhanced chronic ozone (O3) impact was analysed throughout the growing season in the photosynthetic response (ch...

Three and four-year-old saplings of beech (Fagus sylvatica L.) and spruce (Picea abies (L.) Karst.) grown in monoculture and mixed culture were exposed in phytotrons to (1) ambient air, (2) elevated pO(3), (3) elevated pCO(2), or (4) elevated pCO(2) plus elevated pO(3). After 5 months, the contents of soluble sugars, starch, soluble amino compounds, non-structural proteins (NSP), as well as red...

1. Phenotypic plasticity allows large shifts in the timing of phenology within one single generation and drives phenotypic variability under environmental changes, thus it will enhance the inherent adaptive capacities of plants against future changes of climate. 2. Using five common gardens set along an altitudinal gradient (100–1600 m asl.), we experimentally examined the phenotypic plasticity...
