Book Synopsis Freshwater Fish Distribution by : Tim M. Berra
Download or read book Freshwater Fish Distribution written by Tim M. Berra and published by University of Chicago Press. This book was released on 2008-09-15 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.

Book Synopsis Animal Biomarkers as Pollution Indicators by : David B. Peakall
Download or read book Animal Biomarkers as Pollution Indicators written by David B. Peakall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both F. Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to man, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on Earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older. Wherever people's ingenuity has led them to change the face of nature significantly, it has not escaped them that a number of biological con sequences, often unfavourable, ensue.
Book Synopsis Parasite Communities: Patterns and Processes by : Gerald W. Esch
Download or read book Parasite Communities: Patterns and Processes written by Gerald W. Esch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: We first discussed the possibility of organizing a symposium on helminth communities in June, 1986. At that time, we were engaged in writing a joint paper on potential structuring mechanisms in helminth communities; we disagreed on a number of issues. We felt the reason for such debate was because the discipline was in a great state of flux, with many new concepts and approaches being introduced with increasing frequency. After consider able discussion about the need, scope and the inevitable limitations of such a symposium, we decided that the time was ripe to bring other ecologists, engaged in similar research, face-to-face. There were many individuals from whom to choose; we selected those who were actively publishing on helminth communities or those who had expertise in areas which we felt were particularly appropriate. We compiled a list of potential participants, contacted them and received unanimous support to organize such a symposium. Our intent was to cover several broad areas, fully recognizing that breadth negates depth (at least with a publisher's limitation on the number of pages). We felt it important to consider patterns amongst different kinds of hosts because this is where we had disagreed among ourselves.

Book Synopsis The Biology and Identification of the Coccidia (Apicomplexa) of Carnivores of the World by : Donald W. Duszynski
Download or read book The Biology and Identification of the Coccidia (Apicomplexa) of Carnivores of the World written by Donald W. Duszynski and published by Academic Press. This book was released on 2018-06-29 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental concept of The Biology and Identification of the Coccidia (Apicomplexa) of Carnivores of the World is to provide an up-to-date reference guide to the identification, taxonomy, and known biology of apicomplexan intestinal and tissue parasites of carnivores including, but not limited to, geographic distribution, prevalence, sporulation, prepatent and patent periods, site(s) of infection in the definitive and (if known) intermediate hosts, endogenous development, cross-transmission, pathology, phylogeny, and (if known) their treatments. These data will allow easy parasite recognition with a summation of virtually everything now known about the biology of each parasite species covered. The last (very modest) and only treatise published on this subject was in 1981 so this book fills a fundamental gap in our knowledge of what is now known, and what is not, about the coccidian parasites that infect and sometimes kill carnivores and/or their prey that can harbor intermediate stages, including many domestic and game animals. - Offers line drawings and photomicrographs of many parasite species that will allow easy diagnosis and identification by both laypersons and professionals (veterinarians, wildlife biologists, etc.) - Presents a complete historical rendition of all known publications on carnivore coccidia for all carnivore families and evaluates the scientific and scholarly merit of each apicomplexan species relative to the current body of knowledge - Provides a complete species analysis and their known biology of all coccidia described from each carnivore lineage and species - Reviews the most current taxonomy of carnivores and their phylogenetic relationships to help assess host-specificity patterns that may be apparent - Evaluates what little cross-transmission work is available to help understand the complexities of those coccidians that use two hosts (e.g., Sarcocystis, Besnoitia, and others) - Provides known treatments for the various parasite genera/species

Book Synopsis Nutrition and Feeding of Fish by : Tom Lovell
Download or read book Nutrition and Feeding of Fish written by Tom Lovell and published by Springer Science & Business Media. This book was released on 1998-11-30 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is now recognized as a viable and profitable enterprise worldwide. As aquaculture technology has evolved, the push toward higher yields and faster growth has involved the enhancement or replacement of natural foods with prepared diets. In many aquaculture operations today, feed accounts for more than one-half the variable operating cost. Therefore, knowledge of nutrition and practical feeding of fish is essential to successful aquaculture. This book is not written exclusively for scientists but also for students, practicing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for different fishes, and digestion and metabolism of nutrients and energy. It discusses nutrient sources and preparation of practical and research feeds. It gives directions for conducting fish nutrition and feeding experiments. Feeding practices for salmonids, channel catfish, tilapias, shrimps and hybrid striped bass are presented. Since the first edition of this book was printed, the National Research Council of the National Academy of Sciences has revised the nutrient requirements for fish. These revisions are in the present edition. Other additions to this revised edition are chapters on nutrition and fish health, and bioavailability of nutrients. Each original chapter has been meticulously revised and updated with new information. Aquaculture is a dynamic area and new technologies are being introduced continuously; therefore, some of the material discussed in this revised edition may become obsolete quickly. Nonetheless, the material presented has been thoughtfully selected and updated to make it of maximum use to persons whose interests range from general aquaculture to animal nutrition to feed manufacture.

Download or read book Imagining Extinction written by Ursula K. Heise and published by University of Chicago Press. This book was released on 2016-08-10 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are currently facing the sixth mass extinction of species in the history of life on Earth, biologists claim—the first one caused by humans. Heise argues that understanding these stories and symbols is indispensable for any effective advocacy on behalf of endangered species. More than that, she shows how biodiversity conservation, even and especially in its scientific and legal dimensions, is shaped by cultural assumptions about what is valuable in nature and what is not.
