    Different nutrient use strategies of expansive grasses Calamagrostis epigejos and Arrhenatherum elatius

    Enhanced nitrogen (N) levels accelerate expansion of Calamagrostis epigejos and Arrhenatherum elatius, highly aggressive expanders displacing original dry acidophilous grassland vegetation in the Podyjí National ...

    The role of Athyrium distentifolium in reduction of soil acidification and base cation losses due to acid deposition in a deforested mountain area

    The tall fern (Athyrium distentifolium Tausch ex Opiz) forms large stands in many deforested sites in Central European mountains. In the present study, we want to demonstrate that the effect of ferns on the leach...

    Effect of nitrogen addition and drought on above-ground biomass of expanding tall grasses Calamagrostis epigejos and Arrhenatherum elatius

    Tall expansive grasses act as serious weeds since they spread intensively and are a important threat to biodiversity of various plant communities. A field experiment was set up based on three sets of paired pl...

    The effect of enhanced nitrogen on aboveground biomass allocation and nutrient resorption in the fern Athyrium distentifolium

    We measured aboveground biomass allocation and resorption of nitrogen (N) and phosphorus (P) in the fronds of a winter-deciduous fern Athyrium distentifolium in ambient and N-enhanced treatments. Studies were don...

    Effect of Manipulated Rainfall on Root Production and Plant Belowground Dry Mass of Different Grassland Ecosystems

    A field experiment was established to quantify the effects of different amounts of rainfall on root growth and dry mass of belowground plant parts in three types of grassland ecosystems. Mountain (Nardus grasslan...

    Soil nutrient heterogeneity and competitive ability of three grass species (Festuca ovina, Arrhenatherum elatius and Calamagrostis epigejos) in experimental conditions

    We studied the effects of differences in root growth and nutrient pool on the competitive ability of Festuca ovina (short grass), Arrhenatherum elatius and Calamagrostis epigejos (tall grasses) grown in monocultu...
