Taschenbuch. Zustand: Neu. Neuware -This special volume is dedicated to the contributions of women ichthyologists. Three colleagues were selected to represent all women ichthyologists, Ethelwynn Trewavas (ET), Rosemary Lowe-McConnell (Ro) and Eugenie Clark (Genie). All have had distinguished professional careers and have contributed in their own ways to their science. The career of each is highlighted by a personal interview with one of the editors of the volume, a bibliography of their lifetime publications, and a biography of their careers. Questions of historical inequities and current controversies in the treatment of women ichthyologists by their peers are raised and addressed by the women themselves. The personal and professional influences of these three women, and other women ichthyologists, are highlighted. A survey article by Pat Brown brings a number of women ichthyologists to the attention of a broader audience, and points the way for a more comprehensive historical consideration of the accomplishments and contributions of women ichthyologists. The volume continues with 16 solicited and contributed papers. ET's studies of taxonomy and life history are echoed in papers on the taxonomy and systematics of marine angelfishes, and of freshwater bitterlings, a review of reproduction in the North Atlantic ichthyofauna, and a comparison of reproductive styles and systematics of African minnows. Ro's studies on ecology, life history and behaviour are paralleled by papers on growth and metabolism in piranha, the community structure in tide pool fishes, and the social system and reproductive patterns in groupers. Genie's pioneering work on sexual roles and sex change, and her field studies of the behaviour of marine fishes are reflected in papers on gonadal structure and environmental sex determination in brook lamprey, sexual patterns in hawkfish, reproduction and systematics in phallostethids, gonadal structure and systematics in gobiids, reproductive and predator avoidance behaviour in razorfish, early ontogeny of an African mouth brooder, and alternative life histories in killifish.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 460 pp. Englisch.

Buch. Zustand: Neu. Neuware -This book is the first complete biography of one of the founders of fishery science, William Edwin (Bill) Ricker (1908 - 2001). Bill is immortalized in the Ricker Curve. He developed the Curve in his studies of stock and recruitment in fisheries, but it has been widely applied in many areas of science. Bill is best known for his contributions to fishery science, but he was also internationally recognized as an entomologist and a scientific editor.This book combines Bill¿s own recollections with contributions from those who knew him and worked with him as a colleague during his multifaceted career. In an article written shortly before his death, Bill gives his own account of his career and intellectual development. A complete bibliography of Bill¿s scientific publications, translations and manuscripts has been compiled by his son Karl, and accompanies this article. Karl has also written a detailed account of Bill¿s early education and his accomplishments in botany and ornithology. Geoff Scudder summarizes Bill¿s contributions to entomology, Jon Schnute provides both personal and professional insights into Bill¿s mathematical accomplishments, and Dick Beamish and Don Noakes present personal recollections of Bill as a scientist and colleague.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 160 pp. Englisch.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Knowledge: A little light expels much darkness _ Bahya ibn Paquda, Duties of the Heart During the early 1970s digital computer techniques concentrated on the computational and interfacing aspects of digital systems and the decade began as the age of both the mainframe computer and the minicomputer. Engineers and system designers needed to know the fundamentals of computer operation and how the practical limitations of the architectures of the day, the memory size, cost and performance could be overcome; it was for this reason that this book was first written. By 1980 the microprocessor revolution had arrived. As a result the microprocessor became a component of a system, rather than a system itself, and the need to understand the behaviour of the device became of even greater importance to the system designer. New developments in mainframe computers were few, with networks of minicomputers taking over their role in many instarices. The 1980 revision of this book took into account the major advances in semiconductor technology that had occurred since it was first published in 1972, and included material relevant to the microprocessor.

Taschenbuch. Zustand: Neu. Neuware -This book documents the current state of research by Chinese scientists on fish biology and fisheries and brings together manuscripts by authors from research institutions, universities and government agencies. There are papers on aquaculture, life history, genetics, marine and freshwater biology, conservation, physiology, new species descriptions, and truly amazing hypogean fishes. The information on these remarkable cave species shows how much we have yet to learn from that incredible fauna. There are papers dealing with some of the largest fishes and some of the smallest cave species. There are papers dealing with some of the most traditional forms of aquaculture and others with the most modern molecular techniques. The volume includes papers on critically threatened native fishes as well as the most common food species, such as grass carp (Ctenopharyngodon idella). The information on rare and threatened species shows how China is dealing with their endangered fishes. The information on their carp species will be invaluable to those in other countries who will either take advantage of the productive carp species in aquaculture or try to manage them as invasive species outside China. For the first time we bring together a complete overview of the state of fisheries research in China.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -While there has been a long history of salmon hatchery operations throughout the North Pacific, only recently have we begun to investigate how hatchery salmon interact with their wild counterparts. This volume represents our latest understanding of the scale and magnitude of effects of hatcheries on wild salmon populations, and begins to lay the groundwork for precautionary fisheries management to ensure that wild salmon are conserved. Reprinted from Environmental Biology of Fishes volume 94 issue 1Research on hatchery and wild salmonid interactions is increasing exponentially and this book provides a synthesis of what researchers believe today. Of greatest importance is that it shows how little we know.

Buch. Zustand: Neu. Neuware -This volume constitutes the most recent and most comprehensive consideration of the largest family of bony fishes, the Cichlidae. This book offers an integrated perspective of cichlid fishes ranging from conservation of threatened species to management of cichlids as invasive species themselves. Long-standing models of taxonomy and systematics are subjected to the most recent applications and interpretations of molecular evidence and multivariate analyses; and cichlid adaptive radiations at different scales are elucidated. The incredible diversity of endemic cichlid species in African lakes is revisited as possible examples of sympatric speciation and as serious cases for management in complex anthropogenic environments. Extreme hydrology and bathymetry as driver of micro-allopatric speciation is explored in the African riverine hotspot of diversity of the lower Congo River.Dramatic new molecular evidence draws attention to the complex taxonomy and systematics ofNeotropical cichlids including the crater lakes of Central America. Molecular genetics, genomics, imaging tools and field study techniques assess the roles of natural, sexual and kin selection in shaping cichlid traits and beyond. The complex behavioral adaptations of cichlids are considered from a number of sub-disciplines including sensory biology, neurobiology, development, and evolutionary ecology. Most importantly, this volume puts forth a wealth of new interpretations, explanatory hypotheses and proposals for practical management and applications that will shape the future for these remarkable fishes in nature as well as their use as models for the study of biology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 844 pp. Englisch.
