This study was carried out to evaluate gap characteristics and gapmakers for different development stages of an oriental beech forest in northern Iran. Development stages of 1 ha square-shaped mosaic...
The paper presents the evaluation of data on precipitation totals and on SO42 concentrations and S-SO42 fluxes in lysimetric waters in a submontane beech stand. The records cover continually a 1...
The aim of this paper is to present the results of the investigation on belowground biomass and its annual increment in a beech ecosystem (Calamintho grandiflorae-Fagetum) in Mavrovo National Park, Re...
The phenology of four deciduous forest tree species (Carpinus betulus L., Fagus sylvatica L., Quercus dalechampii Ten., Tilia cordata Mill.) was studied in a submountain beech forest stand in Central ...
The paper deals with throughfall and soil percolation in a sub-mountain beech forest situated at the Ecological Experimental Site (EES) Kremnické vrchy Mts. (the West Carpathian Mts., Slovakia). The r...
The paper deals with research on the biomass production of fruiting bodies of macromycetes in a submountain beech stand in dependence on selected climatic variables. The study was carried out at the E...
The aim of this paper is to contribute to the knowledge of dynamics of species diversity, abundance, distribution of fruiting bodies and dominance of macromycetes in mycocoenosis of beech monocultures...
The paper summarizes the results of long-term measurements of soil temperature. The measurements were performed at two depths: 5 cm and 20 cm, on a series of five experimental plots with different sto...
The formation, size distribution and percentage of gaps in two virgin deciduous forests are presented in two case studies. Gaps are defined as openings in the canopy above 2/3 of stand height. These g...
Study on dead wood is necessary for arrive to stability forest management and management with nature. Thus in this study attempted to therewith survey in quantity and species of dead wood at permanen...
On the basis of data obtained from various regional forest management plans as well as from the already carried out research, review of literature and stand dynamics modelling, the article presents th...
Our article focuses on a description of the new subassociation Omphalodo-Fagetum (Tregubov 1957) Marin~ek et al. 1993 rhododendretosum hirsuti (Urban~i~ et al. 1979 nom. nud.) subass. nova, as found o...
In hydrological models, evaporation from interception is often disregarded, combined with transpiration, or taken as a fixed percentage of rainfall. In general interception is not considered to be a s...
This paper deals with the required width of forest road formation. Forest roads are necessary for emergency forest management. Besides positive effects, forest roads also bring negative effects. One...
Spring time nitrous oxide (N2O) emissions from an old beech (Fagus sylvatica L.) forest were measured with eddy covariance (EC) and chamber techniques. The aim was to obtain information on the spatial...
