Lichenologist, William Purvis here explores the unusual biology, amazing diversity and ecological importance of lichen. The text explains how understanding lichen biodiversity may lead to technological developments in medicine, metal prospecting and pollution control. It includes information on economic uses and outlines practical project ideas.
William Purvis (O.W. Purvis) became a lichenologist at The Natural History Museum in London in 1988. He is actively involved in using lichens as bioindicators of environmental health.
This is a great introductory book to the study of Lichens. If it has a fault it is written for the British audience and I wonder will North Americans be able to find the same Lichen as those that grow on the British Isles.
