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.

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 provides a practical guide to experimental methods for studying the development of invertebrate deuterostomes, such as sea urchins, ascidians, hemichordates, and amphioxus. These model organisms are of contemporary and historical importance to the study of developmental biology, particularly genomic research. The chapters provide detailed experimental protocols that cover a broad range of topics in modern experimental methods. Topics covered range from rearing embryos to the care of adult animals, while also presenting the basic experimental methods including light and electron microscopy, used to study gene expression, transgenics, reverse genetics, and genomic approaches. * Covers a wide range of methods, from classical embryology through modern genomics * Discusses animals related to vertebrates, providing a valuable evolutionary perspective * Includes a practical guide to the use of sea urchins in the teaching laboratory

Throughout the four hundred thousand years that humanity has been collecting fossils, sea urchin fossils, or echinoids, have continually been among the most prized, from the Paleolithic era, when they decorated flint axes, to today, when paleobiologists study them for clues to the earth’s history. In The Star-Crossed Stone, Kenneth J. McNamara, an expert on fossil echinoids, takes readers on an incredible fossil hunt, with stops in history, paleontology, folklore, mythology, art, religion, and much more. Beginning with prehistoric times, when urchin fossils were used as jewelry, McNamara reveals how the fossil crept into the religious and cultural lives of societies around the world—the roots of the familiar five-pointed star, for example, can be traced to the pattern found on urchins. But McNamara’s vision is even broader than that: using our knowledge of early habits of fossil collecting, he explores the evolution of the human mind itself, drawing striking conclusions about humanity’s earliest appreciation of beauty and the first stirrings of artistic expression. Along the way, the fossil becomes a nexus through which we meet brilliant eccentrics and visionary archaeologists and develop new insights into topics as seemingly disparate as hieroglyphics, Beowulf, and even church organs. An idiosyncratic celebration of science, nature, and human ingenuity, The Star-Crossed Stone is as charming and unforgettable as the fossil at its heart.

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

From the fiercest predator to the lowliest plant, every member of an ecosystem is immeasurably important to the survival of their environment. Although they're not regarded as a keystone species, sea urchins play a pivotal role in maintaining healthy marine environments. Without sea urchins to consume algae, entire coral reef ecosystems could collapse. This educational text invites readers to imagine a world without sea urchins, delving into curricular science concepts, such as interdependence of species, with accessible language and real-world examples.

Sea urchin eggs are objects of wonder for the student who sees them for the first time under the microscope. The formation of the fertil ization membrane after insemination, the beauty of mitotic cleavage, the elegant swimming of embryos, remain an esthetic pleasure even for the eyes of seasoned investigators. But sea urchin eggs have other, more practical, advantages: they lend themselves to surgical operation without difficulty and they heal perfectly; they can be obtained in very large amounts and represent thus an extremely favorable material for biochemists and molecular embryologists. It is not surprising that, in view of these exceptional advantages, sea urchin eggs have attracted the interest of innumerable biologists since O. HERTWIG discovered the fusion of the pronuclei (amphimixy), in Paracentrotus lividus, almost a century ago. The purpose of the present book is to present, in a complete and orderly fashion, the enormous amount of information which has been gathered, in the course of a hun dred years of sea urchin embryology. JOSEPH NEEDHAM, in 1930, was still able to present all that was known, at that time, on the biochemistry of all possible species of developing eggs and embryos in his famous "Chemical Embryology" (Cambridge University Press) . It would no longer be possible for one man to write a modern version of what was a "Bible" for the young embryologists of forty years ago.
