Genes in the Environment

Molecular, genetic and modelling techniques are central to ecology, providing valuable new tools for addressing complex ecological questions and insights into our understanding of the dynamics of populations and communities. Genes in the Environment reviews a diverse range of topics, including community dynamics in soils and water, gene flow and spatial dynamics, and the evolution of pathogenic and symbiotic relationships. Organisms studied range from bacteria, viruses and fungi to insects, plants and fish. New light is thrown on such questions as: what is the relationship between population dynamics and spatial patterns of genetic variation observed in fragmented populations? How is genetic variation maintained? What are the relative roles of gene flow and selection in the maintenance of climes? This volume will appeal to advanced students and to researchers interested in developments at the interface of molecular biology and ecology.
