Sperm Competition and Sexual Selection presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior. This book provides a theoretical framework for the study of sperm competition, which is a central part of sexual selection. It also discusses the roles of females and the relationships between paternal care in sperm competition. The chapters focusing on taxonomic development are diverse and cover all the major animal groups, both vertebrate and invertebrate, and plants. The final chapter provides an overview discussing the relationship between sperm competition and sexual selection in terms of both function and mechanism and how these translate into species fitness. This book will be of prime interest to behaviorists, ecologists and evolutionary biologists, suggesting new avenues of research and new ways of approaching old problems. more...

This important book contains a great wealth of practical information on trout and salmon, species of fish that are of huge scientific and commercial interest. The introductory chapters of Trout and Salmon cover the biology and environmental variables of importance when considering these species. Further chapters encompass current information on the ecology of salmon and trout, with particular emphasis on the definition and quantification, where possible, of their environmental requirements and limitations. Comprehensive coverage of the impacts of human activities on trout and salmon is included, together with important aspects of relevance when considering issues of species conservation and habitat restoration. The book concentrates on the two species of the genus Salmo with many references and comparisons with the genus Oncorhynchus. Conclusions drawn within the book apply to both genera and as such the book will have relevance for both Europe and North America as well as other areas where these genera occur. Trevor Crisp has written a book that will be of great interest and use to fish biologists and fisheries scientists, to aquatic biologists, conservationists, ecologists and environmental scientists. The book will be particularly valuable for those working in government environment agencies and fish and wildlife departments and to all those involved in the management of these important species, their fisheries and habitats. more...
