Processes of Vegetation Change (Studies; 141)

This book is about ideas on the nature and causes of temporal change in the species composition of vegetation. In particular it examines the diverse processes of inter­ action of plants with their environment, and with one another, through which the species composition of vegetation becomes established. The first chapter considers the general nature of vegetation and the ways in which vegetation change is perceived by ecologists. Chapters 2 and 3 provide essential background about the relationships between plants and their abiotic and biotic environment. Anyone who is familiar with the fundamentals of plant ecology may prefer to pass over Chapters 2 and 3 which, of necessity, cover their subject matter very briefly. Sequences of development of vegetation on new volcanic rocks, sand dunes and glacial deposits, respectively, are outlined in Chapters 4, 5 and 6. Chapter 7 is about the patterns of vegetation change which occur in severe habitats around the world, and Chapter 8 discusses wetlands. Chapter 9 discusses the diverse responses of temperate forests to a variety of disturbing influences, and Chapter 10 deals with change in the species-rich forests of the Tropics. Chapter 11 treats, in detail, the empirical and inferential data on the biological processes occurring during vegetation change sequences. Chapter 12 considers the plant community phenomena which are implicated in the development of theory about vegetation change. The final chapter, Chapter 13, draws the diverse themes together into a unified theoretical structure by which the vegetation change phenomena may be understood.
