Southern Wonder
Southern Wonder explores Alabama’s amazing biological diversity, the reasons for the large number of species in the state, and the importance of their preservation. Alabama ranks fifth in the nation in number of species of plants and animals found in the state, surpassed only by the much larger western states of California,Texas, Arizona, and New Mexico. When all the species of birds, trees, mammals, reptiles, amphibians, fishes, wildflowers, dragonflies, tiger beetles, and ants are tallied, Alabama harbors more species than 90 percent of the other states in the United States. Alabamais particularly rich in aquatic biodiversity, leading the nation in species of freshwater fishes, turtles, ...
Biology and Conservation of Horseshoe Crabs
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.
Living Fossils
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.
The Narrow Edge
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 th...
Invertebrate Pathology
This book assembles an international team of the leading specialists in the field to review the main diseases and pathologic manifestations of all the major invertebrate groups, whilst describing their emergence in contexts such as climate change and global food security.
Catch and Release
The unexpected and fascinating interspecies relationship between humans and horseshoe crabs. Horseshoe crabs are considered both a prehistoric and indicator species. They have not changed in tens of millions of years and provide useful data to scientists who monitor the health of the environment. From the pharmaceutical industry to paleontologists to the fishing industry, the horseshoe crab has made vast, but largely unknown, contributions to human life and our shared ecosystem. Catch and Release examines how these intersections steer the trajectory of both species’ lives, and futures. Based on interviews with conservationists, field biologists, ecologists, and paleontologists over three y...
