Abstract: 6 fig. 1 tab. [Comparison of laboratory and field studies on Xanthoria calcicola and Lecanora muralis. "It is concluded that blockage of diffusive pathways for CO2 in the thallus through high water contents is an important ecological factor for productivity of these central European epilithic lichens.]
