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...
