520			_aProcesses of vegetation change presents a wide-ranging, well-illustrated account of vegetation dynamics, a vital subject for plant ecologists and land managers. The main thrust of the text is the development of novel concepts and theories which relate to the full range phenomena that occur in natural vegetation and which emphasize the important and distinctive roles of individual plant species. Early chapters concentrate on the essential background information relevant to change processes, with examples drawn from a wide range of localities. Particular attention is paid to the nature of reciprocal interactions between plants and their habitats and other organisms. Events that occur during the colonization of new sites and the consequent modifications of habitat conditions are carefully outlined. Long-term sequences of change are explored using chrono-sequences and fossil data from wetland sites. Cyclical replacement sequences, direct replacements and fluctuations are considered in the context of short and long-term changes, with due attention given to the conceptual importance of appropriate scales of time and space. These ideas are developed into a coherent expression of the complexity of the interactive processes operating in the plant/environment system. Current theories of vegetation change are threaded through the text, which leads up to a final section presenting a new theoretical framework based on proximate causes, which affords a fresh appreciation of vegetation change mechanisms. The text contains many original illustrations and makes use of worlwide example data from the tropics to sub-polar regions and from sea shores, through deserts, grasslands and forests to alpine regions, but with particular emphasis on North American locations. The wealth of detail and clear presentation make this book an essential reading item for students of plant ecology, forestry and land systems management.
