The carbon isotope ratios were measured for six species of lichens and seven species of mosses in northern Michigan. All species appear to utilize C3 photosynthesis to take up atmospheric CO2. The lichens had a mean isotope ratio that was 2.4% more positive than the mean value for the mosses, and the difference was significant at the 0.01 level of probability.
