Orthoptera assemblages of beech stand plots during early succession stages after clearcutting
deforestation Ensifera Caelifera deciduous forest corridors central Europe
2015/4/24
Open habitats in closed forests are formed by various biotic and abiotic factors. These new habitats differ from their former parent stands in light conditions and vegetation structure facilitating th...
Phenology of common beech (Fagus sylvatica L.) along the altitudinal gradient in Slovakia (Inner Western Carpathians)
beech forests phenological phases altitude Burda Mts Kremnické vrchy Mts. Poľ ana Mts
2015/4/24
The onset and course of selected vegetative phenological phases of beech along the altitudinal gradient in Slovak Republic were studied. Observations were done in the Burda Mts. (200–300 m a.s.l.), Kr...
Development of target (crop) trees in beech (Fagus sylvatica L.) stand with delayed initial tending and managed by different thinning methods
European beech target (crop) trees different tending
2015/4/24
We evaluated the research on silviculture-production in the last 45 years in a 105-year-old beech stand, not tended up to its stand age of 60 years. Four alternatives (tending regime) were studied for...
Belowground biomass and its annual increment in a montane beech forest in Mavrovo National Park, north-west Macedonia
root biomass coarse roots fine roots trees shrubs beech ecosystem
2015/4/14
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 influence of selected factors on energy requirements for plain milling of beech wood
angular geometry beech cutting input cutting speed false heart feed speed milling
2015/3/19
The paper deals with differences in energy requirements for cutting input at plain milling of beech wood with and without false heart with different changing parameters of cutting and feed speed and a...
Effect of gibberellic acid and ethephon on the germination of European beech dormant and chilled beechnuts
ethephon Fagus sylvatica germination gibberellic acid
2015/3/19
The effect of ethephon (80, 100 and 120 mg·l–1) and gibberellic acid (GA3) (40, 300 and 1,000 mg·l–1) on the germination capacity (GC) and mean germination time (MGT) of European beech (Fagus sylvatic...
Extent and distribution of beech (Fagus sylvatica L.) regeneration by adult trees individually dispersed over a spruce monoculture
beech dispersed trees forest dynamics regeneration transformation of spruce monocultures
2015/3/19
Recently individually dispersed adult beech trees have regenerated in spruce monocultures and this fact could be used to manage the transformation of stands into a mixed forest. Three such cases in th...
Models for predicting aboveground biomass of European beech (Fagus sylvatica L.) in the Czech Republic
beech biomass function temperate forests tree allometry wood density
2015/5/6
We developed optimal models for predicting the aboveground biomass of European beech (Fagus sylvatica L.) applicable to the national forest inventory data of the Czech Republic. The models were based ...
Biomass functions applicable to European beech
allometry aboveground tree biomass branch stem carbon wood density
2015/2/6
This material describes parameterization of allometric functions applicable to biomass estimation of European beech trees. It is based on field data from destructive measurements of 20 full-grown tree...
The influence of stand density on Mn and Fe concentrations in beech leaves
Fagus sylvatica L. leaf concentration iron manganese shelterwood cutting
2015/2/6
A shelterwood system is widely used in forest management practice. Favourable ecological conditions for the growth of desired natural seedlings are provided by a successive canopy reduction. The impac...
