Much contemporary ecological research is being carried out in tropical communities - they are among the most species-rich and dynamic communities in the world. Special characteristics of tropical communities have been recognized - unpredictability at the individual and species level, the uniqueness of location and time period studied, and the importance of major chance environmental events. Tropical ecologists must now set these processes against the long-term directional changes that are happening regionally and globally to answer new questions. The demands on tropical ecologists are to be increasingly prescriptive rather than descriptive, and this presents new challenges. A new conceptual framework is required, and the authors and editors of this book hope to signal how such a framework might be developed.

Tropical communities are recognised as among the most species-rich and dynamic in the world. Yet far from existing as dynamic equilibria, large unpredictable disruptive events are seen as dominating the longer-term dynamics set against the background of global change. This 1998 volume challenges the dynamic equilibrium idea yet further, arguing for thinking on a timescale of decades to centuries, finding different ways to handle unpredictability and uniqueness, and evaluating species diversity and community change at different scales. The difficult search for robust generalizations and rules in tropical communities, which might allow better prescription through understanding rather than description is partly answered in this forward-looking book by the realization that an alternative framework and perspective is required for the tropics. This volume will continue to appeal to both researchers and advanced students of ecology.
