Adaptive dynamics is a fast growing and increasingly important area of theoretical ecology. As it is a relatively young field, publications in the area have been scattered through the literature, and manu of its more important findings and applications have not been brought to the attention of a wider readership. This volume provides a state of the art survey of the field by the world's leading reseachers, pulling together material published in a variety of fields to provide a lauching pad for future research.
