The relationship between net photosynthesis and CO(2) concentration was investigated for four species of lichen using an infrared gas analyzer operating in a closed loop system. All species showed a linear relationship at low CO(2) levels (100 microliters per liter) with CO(2) saturation levels being in excess of 400 microliters per liter. Detailed studies of Sticta latifrons showed a strong influence of thallus water content which resulted in the net photosynthetic response at high water… CONTINUE READING
