In order to quantify the impacts of silvicultural treatments in semiarid forests, it is necessary to know how they affect key aboveground processes and also properties characterizing the forest floor ...
The effect of thinning on litterfall and decomposition of biomass was investigated in Norway spruce IUFRO thinning experiment (CZ-13), Czech Republic. The experiment was established in 1971 in an 8-ye...
To keep forest soils fertile, forest practitioners plant mixed stands that are composed of both economically efficient trees such as conifers and soil-improving broadleaves. This is a mandated practic...
Forest ecosystems of the Krušné hory Mts. affected by long-term air pollution were finally disintegrated. The tree species composition has been changed in ecosystems disturbed in this way. Liming...
Altitudinal studies has become of interest to ecologists concentrated on functional alterations aiming to clarify the effects of limiting factors. Nutrient element release from forest floor (FF) decom...
This study reports continuous automated measurements of forest floor carbon (C) exchange over feathermoss, lichen, and sphagnum micro-sites in a black spruce forest in eastern North America during sno...
Soil erosion has been progressing over a large area in Doudaira (located in East Tanzawa of Kanagawa Prefecture) due to the sika deer (Cervus nippon) feeding which has in turn resulted in a reduction ...
Forest-floor vegetation and regeneration of tree species were investigated inside and outside a deer-proof fence that had been constructed 7 years earlier in a cool temperate deciduous forest in the T...
To estimate the downslope distance of leaf-litter transport in a given time on the forest floor, we conducted a field experiment with artificial leaves and used the data to construct two models for th...
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 study focuses on spatial variability of throughfall water and chemistry and forest floor water content within a Douglas fir (Pseudotsuga menziesii, Franco L.) forest plot. Spatial patterns of wat...
This study focuses on spatial variability of throughfall water and chemistry and forest floor water content within a Douglas fir (Pseudotsuga menziesii, Franco L.) forest plot. Spatial patterns of wa...
A state-dependent, dynamic forest floor development model is presented. The model considers litterfall as input. The decomposition of the litter was modelled as influenced by the quality of litter and...
Emissions of various C2-C10 hydrocarbons (VOCs) and halogenated hydrocarbons (VHOCs) from a boreal wetland and a Scots pine forest floor in south-western Finland were measured by the static chamber te...
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...
