Abstract
What are the genetic consequences of dispersal? This is a question which includes many controversial components. Does environmental heterogeneity maintain genetic variation, and if so, how does dispersal interact with this heterogeneity to affect levels of variability? Does gene flow bind a species together into a homogeneous unit, or can adaptation and divergence occur despite free intermingling? Do genetic factors, such as levels of inbreeding, or of variability, determine the evolution of dispersal itself? Several chapters in this book (e.g. Chapters 1, 4, 5 and 9) consider this question. This chapter therefore concentrates on the effects of environmental heterogeneity and gene flow on patterns of genetic variation, rather than on the evolution of dispersal itself; examples are drawn from a wide variety of taxa.
