Mountain ecosystems and cold deserts are especially rich in lichens and are excellent field laboratories to study them under various stress conditions. The 17 reviewed contributions in this volume cover lichens from the European Alps, tropical Africa, the La Soufri#re volcano and Dronning Maud Land, Antarctica.
