Abstract: 3 figures. [Studies done on 4 lichen species from New Zealand. "The results differ from previous studies which reported low CO2 saturation levels (200 microliters per liter) and no apparent effect of water content. It is suggested that some of these differences may result from the use of discrete sampling injection infrared gas analyzer system in the earlier studies and an assessment is made of the influence of nonsaturating CO2 levels, lack of cuvette ventilation, and data presentation for this technique."]
