| Summary: | SUMMARY The seasonal changes in the ability of Cladonia rangiferina to tolerate heat stress are examined in late winter, early spring and in summer. The effects of heat stress are examined as changes in net photosynthetic and respiration rates following air‐dry storage of lichen replicates at two stress temperatures, 35 and 45 °C, for 21 days. In late winter the experimental replicates show reduced net photosynthetic rates after 7 days stress treatment at 35 °C. By mid‐summer this treatment has no deleterious effects and it is concluded that there is approximately a 10 °C increase in heat tolerance in Cladonia rangiferina between late winter and mid‐summer. |
