The photosynthesis of Antarctic mosses and lichens have been measured since the 1960's. Most of the measurements were performed with the objective of elucidating the relationships between photosynthetic rate and environmental factors, especially irradiation intensity and temperature. In the 1970's, live samples were transported to domestic laboratories and their activities were measured under controlled conditions. Recently, information obtained from further field measurements have enabled the modelling of the relationships between photosynthesis and environmental factors using with multiple regression analysis.
