Includes bibliographical references



Written by Dr. George Sugihara, this pioneering work represents a unifying synthesis to tie together four disparate areas of ecology: 1) topological structure of food webs; 2) ecosystem dynamics; 3) ecosystem/food web assembly; and 4) universal patterns of species abundance. Based on the premise that deep general principles are likely to be associated with widely observed empirical regularities, it is organized around uncovering and explaining such patterns for each of the four research areas, and then showing how they interrelate. While this book has historic interest, it is even more relevant today in its findings and overall scope.
