Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins are a major component of marine environments found throughout the world's oceans. A major model for research in developmental biology, they are also of major economic importance in many regions and interest in their management and aquaculture has increased greatly in recent years. This book provides a synthesis of biological and ecological characteristics of sea urchins that are of basic scientific interest and also essential for effective fisheries management and aquaculture. General chapters consider characteristics of sea urchins as a whole. In addition, specific chapters are devoted to the ecology of 17 species that are of major commercial interest and ecological importance. Features include: • A synthesis of what is known about the basic biological characteristics of the sea urchin, useful for the direction of future research. • Case histories of 17 species that illustrate their ecological role in a variety of environments. • With the catastrophic decline in fisheries resulting primarily from over-fishing, it is essential that the populations be managed effectively and that aquaculture be developed. This book provides knowledge of the biology and ecology of the commercially important sea urchins that will contribute to these goals. • The only book available in present literature devoted to sea urchins. With this new title experts provide a broad synthetic treatment and in depth analysis of the biology and ecology of sea urchins from around the world, designed to provide an understanding of the group and the basis for fisheries management and aquaculture.

Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins are a major component of the world ocean. They are important ecologically and often greatly affect marine communities. They have an excellent fossil record and consequently are of interest to paleontologists. Research has increased in recent years stimulated first by a recognition of their ecological importance and then because of their economic importance. Scientists around the world are actively investigating their potential for aquaculture. This book is designed to provide a broad understanding of the biology and ecology of sea urchins. Synthetic chapters consider biology of sea urchins as a whole to give a broad view. The topics of these chapters include reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition.

Download or read book Sea Urchin written by Maria Agnello and published by BoD – Books on Demand. This book was released on 2017-10-04 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is addressed to the readers operating in the sea urchin field of research, as well as to the lovers of this fascinating organism. Sea urchin, among the most known marine invertebrates belonging to the deuterostomes, is more closely related to humans than other invertebrates, thus representing a suitable model system not only for developmental biology and ecotoxicology but also for biomedicine. The topics described highlight the validity and versatility of this organism for different kinds of investigations. A collection of interesting chapters contributes to this volume and clearly shows the reason of the high interest manifested by a huge number of scientists around the world for this organism over time. Each contribution is a separate and comprehensive chapter but within the book's aim.

Book excerpt: This fully revised and expanded edition of Sea Urchins provides a wide-ranging understanding of the biology and ecology of this key component of the world's oceans. Coverage includes reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition. Other chapters consider the ecology of individual species that are of major importance ecologically and economically, including species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. In addition, six new contributions in areas such as immunology, digestive systems and community ecology inform readers on key recent developments and insights from the literature.Sea urchins are ecologically important and often greatly affect marine communities. Because they have an excellent fossil record, they are also of interest to paleontologists. Research on sea urchins has increased in recent years, stimulated first by recognition of their ecological importance and subsequently their economic importance. Scientists around the world are actively investigating their potential for aquaculture and fisheries, and their value as model systems for investigations in developmental biology continues to increase. Continues the series "Developments in Aquaculture and Fisheries Science" with a newly revised volume Collects and synthesizes the state of knowledge of sea urchin biology and ecology Expanded from previous edition to include non-edible species, providing the needed basis for broader evolutionary understanding of sea urchins

Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins and sea cucumbers are highly sought after delicacies growing in popularity globally. The demand for these species is rapidly outpacing natural stocks, and researchers and seafood industry personnel are now looking towards aquaculture as a means of providing a sustainable supply of these organism. Echinoderm Aquaculture is a practical reference on the basic biology and current culture practices for a wide range of geographically diverse echinoderm species. Echinoderm Aquaculture begins by examining the basic ecology and biology of sea urchins and sea cucumbers as well as the breadth of uses of these organisms as a source of food and bioactive compound. Subsequent chapters delineate the specific species of interest invarious geographic regions from around the world. Together, chapters provide a comprehensive coverage of culture practices. Echinoderm Aquaculture is a practical reference for researchers and industry personnel, and will serve as an invaluable resource to this rapidly growing segment of the aquaculture industry.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In eastern Canada, the destruction of foundational kelp beds by dense aggregations (fronts) of the omnivorous green sea urchin, Strongylocentrotus droebachiensis, is a key determinant of the structure and dynamics of shallow reef communities. Current knowledge about factors affecting the ability of S. droebachiensis to exert top-down community control is based largely on observational studies of patterns in natural habitats, yielding fragmentary, and sometimes contradictory, results. The present research incorporated laboratory microcosm experiments and surveys of urchins in natural habitats to test the effects of abiotic (wave action, water temperature) and biotic (body size, population density) factors on: (1) individual and aggregative feeding on the winged kelp, Alaria esculenta; and (2) displacement, microhabitat use, distribution, and aggregation in food-depleted habitats. Wave action, water temperature, and body size strongly affected the ability of urchins to consume kelp: individual feeding increased with increasing body size and temperature, while aggregative feeding decreased with increasing wave action. Yet, feeding in large urchins dropped by two orders of magnitude between 12 and 18°C. Increasing wave action triggered shifts in urchin displacement, microhabitat use, distribution, and aggregation: urchins reduced displacement and abandoned flat surfaces in favour of crevices. They increasingly formed two-dimensional aggregations at densities ≥110 individuals m−2. Collectively, results provide a foundational understanding of some of the drivers of feeding and spatial dynamics of S. droebachiensis and potential impacts on the formation of grazing fronts.
