Godfray is a Professor of Evolutionary Biology and Director of NERC Centre for Population Biology Klappentext Recent research in the rapidly developing field of molecular, genetic and modelling techniques provides valuable new tools for addressing complex ecological questions and considerable insights into our understanding of the dynamics of populations and communities. The diverse range of topics covered in this volume includes community dynamics in soils and water, gene flow and spatial dynamics, and the evolution of the pathogenic and symbiotic relationships. Organisms studied range from bacteria, viruses and fungi to insects, plants and fish. Zusammenfassung What is the relationship between population dynamics and spatial patterns of genetic variation in fragmented populations? How is genetic variation maintained? What are the relative roles of gene-flow and selection in the maintenance of climes? Genes in the Environment throws new light on these questions by reviewing the recent research.
