Abstract

The desiccation-tolerant (DT) moss Tortula ruralis and the DT lichen Cladonia convoluta, collected from a dry sandy grassland in Hungary, were grown for 4 months at present (350 μmol mol-1) and elevated (700 μmol mol-1) CO2 concentrations in open-top chambers. Subsequent measurements showed no change in total chlorophyll, soluble sugar, starch or protein-N content in either species; short-term responses of gas exchange and chlorophyll fluorescence to drying out and remoistening were also substantially unaltered. The response of net CO2 uptake to ambient CO2 concentration at saturating irradiance and optimum water content showed either no change (C. convoluta) or (in Tortula ruralis) no change in the initial slope of the A/Ca curve and a small but significant enhancement of uptake at higher CO2 concentrations (i.e. upward acclimation) in material grown at elevated CO2. These results are contrary to most published findings in vascular plants and in the endohydric moss Polytrichum formosum. They suggest that DT bryophytes and lichens may be favoured relative to vascular plants by rising atmospheric CO2 concentration.
