Horseshoe crabs, those mysterious ancient mariners, lured me into the sea as a child along the beaches of New Jersey. Drawn to their shiny domed shells and spiked tails, I could not resist picking them up, turning them over and watching the wondrous mechanical movement of their glistening legs, articulating with one another as smoothly as the inner working of a clock. What was it like to be a horseshoe crab, I wondered? What did they eat? Did they always move around together? Why were some so large and others much smaller? How old were they, anyway? What must it feel like to live underwater? What else was out there, down there, in the cool, green depths that gave rise to such intriguing creatures? The only way to find out, I reasoned, would be to go into the ocean and see for myself, and so I did, and more than 60 years later, I still do.
Thousands of ravenous tiny shorebirds race along the water's edge of Delaware Bay, feasting on pin-sized horseshoe-crab eggs. Fueled by millions of eggs, the migrating red knots fly on. When they arrive at last in their arctic breeding grounds, they will have completed a near-miraculous 9,000-mile journey that began in Tierra del Fuego. Deborah Cramer followed these knots, whose numbers have declined by 75 percent, on their extraordinary odyssey from one end of the earth to the other—from an isolated beach at the tip of South America all the way to the icy tundra. In her firsthand account, she explores how diminishing a single stopover can compromise the birds' entire journey, and how the ...
This book reports significant progress of scientific research on horseshoe crabs, including aspects of evolution, genetics, ecology, population dynamics, general biology and physiology, within the recent 10 years. It also highlights the emerging issues related to world-wide conservation threats, status and needs. The contributions in this book represent part of an ongoing global effort to increase data and concept sharing to support basic research and advance conservation for horseshoe crabs.
Sustainable Management of Urban Plastic Waste Through Circular Economic Approaches covers the technologies and methods essential to overcome single-use plastic processing waste. It describes the biotechnological methods, cutting-edge research, procedures, and applications required to safeguard global sustainable development along with plastic waste management. This book: Describes technological advances made towards remediation and valorization technologies of plastic pollutants to reduce microplastic pollution Focuses on accelerating using single-use plastic waste in value-added products Includes examples and case studies of impact and treatment of plastics in the circular economy Explains the socio-economic benefits of reducing plastic pollution This book will be of interest to researchers, scientists, and engineers working on sustainable management of plastic waste, especially in the chemical and environmental engineering and biotechnology sectors.
Limulus in the Limelight: A Species 350 Million Years in the Making and in Peril? contains 14 chapters covering the horseshoe crab's biology, ecology and evolutionary development. The book is a result of three mini-conferences held between 1996 and 2000 celebrating the populations in NY harbor. This book exposes the impacts of over fishing on this species; clarifies the future research agenda for the species worldwide and emphasizes the need for conservation of this fascinating creature's estuaries/ocean habitats. Biologists, ecologists, science educators, and conservationists will welcome this book because it is aimed at the preservation of Limulus, not only for its pharmacological interest but for the mystery related to its longevity. Limulus is a unique animal which has provided numerous uses for man over the years, from fertilizer to bait to medical research. However, if this species is not protected soon, it will be lost for the future.
Audisee® eBooks with Audio combine professional narration and sentence highlighting to engage reluctant readers! In the history of life on this planet, 99.9 percent of all species have gone extinct. But a few have survived almost unchanged. Author Rebecca E. Hirsch introduces readers to six living fossils, including the chambered nautilus, the horseshoe crab with its sticky blue blood, and venomous platypuses that sting, as well as a comprehensive explanation of evolution and extinction for readers who may not be familiar with the terms yet. Readers will also discover a a spectacular timeline of the history of animal life on Earth. Dive into the stories of these incredible animals and find out how they help scientists piece together evolutionary history.
Dual-layered text introduces the life cycle of the horseshoe crab, with a focus on the annual mass-spawning event at Delaware Bay.
