Summary : 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. Subsequent chapters consider the ecology of individual species that are of major importance ecologically and economically. These include species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. * First comprehensive book devoted to the biology and ecology of sea urchins * NEW chapter on Nutrition of Sea Urchins and Ecology of Diadema * Brand NEW illustrations * Hot NEW topic: Immunology of the Sea Urchin * Chapters written by internationally recognized experts * Each chapter revised and updated from the first edition * Biological chapters include reproduction, endocrinology, carotenoids and disease * Ecological chapters include species of major economic interest for fisheries and aquaculture

Summary : Sea urchins play a key role in marine ecosystems, controlling through its grazing activity the dynamic, structure and composition of seaweed and sea grasses. Moreover, it is a crucial component of the food web, as prey for fishes and other marine animals. Due to its sedentary habits and sensitivity to pollutants, adult sea urchin has been used in several studies as a biological-biochemical indicator of local pollution. This book provides several topics on sea urchins. It discusses the phenotypic variation and resilience in sea urchin morphogenesis; response of sea urchins to environmental stress; nonparametric regression applied to sea urchin growth; and sea urchin immune systems.

Summary : 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.

Summary : Mitosis in sea urchin eggs was retarded following their exposure to magnetic fields higher than 70,000 gauss which had gradients greater than 4200 gauss/centimeter. The degree of retardation was correlated simultaneously to both the field strength and the field gradient. Division delay in fields ranging from 100,000 to a maximum of 120,000 gauss was independent of the gradient. Differences in division delay were found which may be a reflection of the differential migration of oxygen and nitrogen due to their para- and diamagnetic properties. An hypothesis is given concerning the biochemical processes affected by magnetic fields. (Author).
