Description: Das Projekt "Der Einfluss gesteigerter CO2-Konzentration in der Atmosphaere auf die alpinen Oekosysteme" wird vom Umweltbundesamt gefördert und von Universität Basel, Departement Integrative Biologie, Botanisches Institut durchgeführt. During this project natural alpine heathland dominated by the sedge Carex curvula is exposed to elevated CO2. The research site is situated an the main divide of the Swiss Alps at 2500 m altitude near the origin of the river Rhone (Furkapass). 32 open-top chambers (16 with ambient, 16 with twince ambient CO2 level) are operated grom snowmelt (late June) to end of season (mid September). Major research components include non-destructive growth analysis (tiller and leaf demography), root dynamics (in-growth cores), carbon balance studies (gas exchange techniques), and the monitoring of the carbohydrate and nutrient relations. Destructive sampling (biomass analysis) will be conducted for the first time in 1995. The results of this project will examplify responses of a rather stable high altitude ecosystems of low species diversity on acid soil.
