Abstract: 1 table. 12 figures. [Studies conducted using Parmelia reticulata and Cladonia portentosa in Portugal are described. Authors give extensive description and explanation of the use of a portable CO2-porometer and the development of a model for lichen CO2 exchange. "Our experience suggests that we can expect to improve our model many times before it satisfactorily reproduces the real-world situation. Instrumentation has been described here which permits these kinds of investigations."]
