Mountain regions are key for humanity's water supply, and their water yield depends on climatic, soil and vegetation effects. Here we explore the effects of vegetation composition and structure on the water balance of high elevation grasslands with d

1. Lianas, which arguably benefit more than other growth forms from elevated CO 2 , have been associated with increasing turn-over rates in tropical forests as observed in recent decades. Although rarely as prominent outside the tropics, an increase

To investigate how plant diversity loss affects nitrogen accumulation in above-ground plant biomass and how consistent patterns are across sites of different climatic and soil conditions, we varied the number of plant species and functional groups (g

To elucidate how atmospheric CO2 enrichment, enhanced nutrient supply and soil quality interact to affect regrowth of temperate forests, young Fagus sylvatica and Picea abies trees were grown together in large model ecosystems. Identical communities

We tested the hypothesis that cultivar selection during the process of domestication in cereal plants led to a change in dry mass allocation, e.g., less root mass and more leaf mass or more leaf area per unit leaf mass. We divided 24 varieties of dip

Interactive effects of increases in atmospheric CO2 and reductions in plant species diversity were investigated in planted calcareous grassland communities in northwestern Switzerland. The experimental communities were composed of 5, 12, and 31 speci

The objectives of this study were to quantify changes in leaf freezing resistance and carbohydrate concentrations caused by long-term (6 years) exposure to elevated CO2(ambient: 360 μl l−1, elevated: 600 μl l−1) in five dominant plant species g

Interactive effects of reductions in plant species diversity and increases in atmospheric CO2 were investigated in a long-term study in nutrient-poor calcareous grassland. Throughout the experiment, soil nitrate was persistently increased at low plan
