From rocky coasts and urban churchyards to rain forests and mountain summits, lichens are a familiar part of the landscape. Each lichen is a miniature ecosystem, consisting of a fungus and one or more photosynthetic partners. This delicate balance between partners is easily upset by environmental disturbance, providing us with practical tools to assess the effects of air pollution, radioactive fall-out and climate change. Lichenologist William Purvis explores their unusual biology, amazing diversity and ecological importance. He explains how the rewards of understanding lichen biodiversity are great and may lead to technological developments in medicine, metal prospecting and pollution control. This unique book includes new information on economic uses and outlines practical project ideas. Packed with stunning photographs 'Lichens' reveals the varied and intriguing world of these fascinating organisms.
