This new book offers a full-scale treatment of British butterfly ecology. We have not had a comparable source-book for many years, and now it comes at a time when many butterfly populations worldwide, including about half the British species, are in decline. The authors bring together new ideas, facts, and figures from recent studies to discuss individual butterfly behaviour and adaptations; population dynamics, community structure, distributions, and habitats; and the underlying genetics and evolutionary pathways. The last chapter focuses on conservation. Information is presented in considerable detail, and the volume includes an extensive glossary, full bibliography, many tables, appendices on hostplants and habitats, and more than ninety figures. Students of butterflies, ecology, and natural history will find it an invaluable reference tool as well as a benchmark in ecological studies. The authors are well known for their work in research, conservation, and education. They are: Roger Dennis, Tim Shreeve, Keith Shreeve, Keith Porter, Martin Warren, Paul Brakefield, Jeremy Thomas, and Caroline Steel. Derek Whiteley prepared the figures.
