Produktbeschreibung

Providing an essential foundation for evolutionary theory, this comprehensive volume examines patterns of genetic variation within natural insect populations, and explores the underlying mechanisms that lead to the genetic divergence of coexisting organisms. In particular, the text investigates current research on finescale genetic structure in natural insect populations. Internationally renowned scientists offer a wealth of current information not previously published. Part I present case studies of adaptive genetic structure in natural insect populations, including a critical discussion of the strenghts and weaknesses of the experimental methods employed. Part II addresses the ecological mechanisms that produce adaptive genetic structure in natural insect populations. Part III describes how behavioral and life-history patterns influence genetic structure. Finally, Part IV combines theoretical and empirical approaches linking genetic structure at the population level with larger-scale patterns of variation, such as host race formation and speciation. This broad-ranging, interdisciplinary source of information supplies a thorough examination of the mechanisms that promote and impede genetic structure in natural insect populations. It is a book that will be of interest to undergraduate and graduate students, and to researchers in the fields of ecology, evolution, insect and plant systems, entomology, and population genetics.
