Description		This book thoroughly reviews literature on rodent dispersal and presents a new interpretation of it. Anderson challenges the assumption that "because animals emigrate, there must have been direct selection for emigratory tendency....Emigrant Fitness Hypothesis," and presents an alternative "Resident Fitness Hypothesis" which he advocates throughout the book. This provocative book is a must for all people interested in animal dispersal.
