This book explores in detail threats to the world's sea turtle population to provide sound, scientific conclusions on which dangers are greatest and how they can be addressed most effectively. Offering a fascinating and informative overview of five sea turtle species, the volume discusses sea turtles' feeding habits, preferred nesting areas, and migration routes; examines their status in U.S. waters; and cites examples of conservation measures under way and under consideration.
Marine biologist James R. Spotila has spent much of his life unraveling the mysteries of these graceful creatures and working to ensure their survival. In "Sea Turtles," he offers a comprehensive and compelling account of their history and life cycle based on the most recent scientific data and suggests what we can be done to save them. Illustrated with stunning, full-color photographs. 0-808-8007-6$24.95 / Johns Hopkins University Press
A study of the leatherback turtle details the distressing decline of sea turtles in the Pacific, as well as their remarkable recovery in the Atlantic to illuminate how human intervention can both harm and preserve the natural world.
Modern marine turtles belong to an ancient group of reptiles inhabiting the Earth for over 110 million years, since the Cretaceous. Marine turtles depend on both marine and terrestrial habitats for their growth and development, from high energy beaches to benthic reefs, and the open waters of the seas. All seven species of sea turtles are listed on the International Union for Conservation of Nature (IUCN) Red List of Threatened Animals (IUCN 2011). The threats facing sea turtles are many, both on land and at sea, including habitat loss, predation, and human exploitation. This book examines the ecology, behavior and conservation efforts of sea turtles.
Illuminating the entangled histories of the people and commodities that circulated across the Atlantic, Sharika D. Crawford assesses the Caribbean as a waterscape where imperial and national governments vied to control the profitability of the sea. Crawford places the green and hawksbill sea turtles and the Caymanian turtlemen who hunted them at the center of this waterscape. The story of the humble turtle and its hunter, she argues, came to play a significant role in shaping the maritime boundaries of the modern Caribbean. Crawford describes the colonial Caribbean as an Atlantic commons where all could compete to control the region's diverse peoples, lands, and waters and exploit the region's raw materials. Focusing on the nineteenth and twentieth centuries, Crawford traces and connects the expansion and decline of turtle hunting to matters of race, labor, political and economic change, and the natural environment. Like the turtles they chased, the boundary-flouting laborers exposed the limits of states' sovereignty for a time but ultimately they lost their livelihoods, having played a significant role in legislation delimiting maritime boundaries. Still, former turtlemen have found their deep knowledge valued today in efforts to protect sea turtles and recover the region's ecological sustainability.
After decades of research, monitoring, and analysis, we still have so much to learn about sea turtles. As reptiles, they are environmentally sensitive animals and thus can sense acute changes in their habitat. This rudimentary tactic of ectothermic animals has possibly conceded to the survival of sea turtle populations over millions of years. They have endured cooling and warming of the earth. The habitats they depend on have endured fierce hurricanes and erosion. Now the question remains if sea turtle populations and their habitats will survive the challenges and pressures that humans place on the world. The anthology of research presented in this textbook is diverse and yet so interconnected. We cannot work to conserve wildlife populations without a fundamental understanding of habitat or the range of changes that individuals within a population can tolerate. Sea turtles are no exception. Changes in migration patterns due to climate change, diversity of food sources between species, acute habitat selection for nesting, mutations in genetics, and differences in anatomy, physiology, and biochemistry between species and even individuals make the study of sea turtles dynamic and challenging.
The Windward Road, published in 1956, made history. When Archie Carr began to rove the Caribbean to write about sea turtles, he saw that their numbers were dwindling. Out of this appeal to save them grew the first ventures in international sea turtle conservation and the establishment of the Caribbean Conservation Corporation. In addition to sea turtle biology, Carr recorded his general impressions, producing a natural history sprinkled with colorful stories.
In April 2007, eleven leatherback turtles captured the imagination of the public worldwide as they “raced” from Costa Rica toward the Galápagos Islands. Known as the Great Turtle Race, this event tracked these critically endangered sea turtles, drawing attention to their fragile status and generating data on the turtles vital to efforts to study and protect them. But the Great Turtle Race is just one of many tools marine conservationists use to inform people about the status, biology, and lives of the seven sea turtle species. Due to human actions, once-plentiful sea turtle population levels plummeted throughout much of the twentieth century, stabilizing somewhat only after Archie Carr and Jacques Cousteau popularized their plight. With Saving Sea Turtles, award-winning author James R. Spotila picks up where Carr and Cousteau left off, going inside the modern-day conservation movement to tell the tales of today’s sea turtle conservationists. He provides a complete overview of sea turtle biology and life cycles, discusses the human and natural world threats they face, and examines the new methods and technologies humans are using to save them. Throughout, Spotila dots the narrative with stories of real-life heroes who risk life and limb to understand, track, and conserve sea turtles across the globe. Spotila has been at the forefront of sea turtle research and conservation for decades. His inspirational story of dedicated individuals, creative endeavors, and adventure reveals what is being done and what else we must do in order to ensure that these fascinating animals continue swimming in the oceans.
The success of the first volume of The Biology of Sea Turtles revealed a need for broad but comprehensive reviews of major recent advances in sea turtle biology. Biology of Sea Turtles, Volume II emphasizes practical aspects of biology that relate to sea turtle management and to changes in marine and coastal ecosystems. These topics i
