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.

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 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.

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.

"A must-purchase picture book biography of a figure sure to inspire awe and admiration among readers."—School Library Journal (starred review) Extraordinary illustrations and lyrical text present pioneering African American scientist Ernest Everett Just. Ernest Everett Just was not like other scientists of his time. He saw the whole, where others saw only parts. He noticed details others failed to see. He persisted in his research despite the discrimination and limitations imposed on him as an African American. His keen observations of sea creatures revealed new insights about egg cells and the origins of life. Through stunning illustrations and lyrical prose, this picture book presents the life and accomplishments of this long overlooked scientific pioneer.
