Reviews

"Provides a timely update on many theoretical issues and includes examples of long-term multidisciplinary studies. . . . deserves a wide audience." --Jack W. Sites, Jr. (Brigham Young University), Science
"Provides in-depth background introducing important concepts and analytical methodologies used in hybrid zone studies. Several excellent illustrative case histories are also presented, highlighting many of the most extensively studied hybrid zones....The concepts, methodologies, and diversity of issues stressed in each of the case histories provide valuable reference material for ecologists and evolutionary biologists regardless of taxonomic affinities or
research interests." --Ecology
"Presents a masterful overview of hybrid zone theory and empirical evidence on the nature of hybrid zones in a variety of organisms....Each of the case studies was extremely interesting, and went beyond reporting of facts, often providing thoughtful and critical interpretations of the data....Would be useful in the libraries of most evolutionary biologists, as a topic for seminars, and a `must acquisition' for university and museum libraries." --American
