They’re powerful, fierce carnivores...and they need our help. Tigers are in very real danger of extinction. Hundreds of years of people hunting tigers and destroying their habitats have drastically reduced their numbers. Now, several countries and wildlife groups have teamed up to save the remaining tigers prowling the forests of Asia. This volume is filled with vivid photographs and fun fact boxes, helping readers learn about the six subspecies of tigers, their behaviors, and the recent efforts to save them.
A sea turtle's life is marked by perilous journeys--to the beach where it lays eggs and as a hatchling to the sea. In addition to its natural predators, it faces great danger from encroaching civilization. This fascinating book describes the different species, their behavior, and how people are trying to save these endangered animals.
Saving the Endangered Green Sea Turtle by Sarah Machajewski Pdf
The green sea turtle is a majestic creature that has been in existence for more than 100 million years. Today, however, green sea turtles are in danger of extinction because of the careless actions of humans. This volume presents facts about the green sea turtle's biology, habitat, mating and nesting habits, and diet, before describing the harmful human behavior that threatens its very existence. With beautiful colorful photographs and practical applications for helping to save this and other endangered creatures, readers will learn the importance of conservation.

Decline of the Sea Turtles by National Research Council,Division on Earth and Life Studies,Commission on Life Sciences,Committee on Sea Turtle Conservation Pdf
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
Presents general information about the seven species of sea turtles, the dangers that they face that threaten their survival as a species, and the work that is done to protect them.
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.

Assessment of Sea-Turtle Status and Trends by National Research Council,Division on Earth and Life Studies,Ocean Studies Board,Committee on the Review of Sea-Turtle Population Assessment Methods Pdf
All six species of sea turtles found in U.S. waters are listed as endangered or threatened, but the exact population sizes of these species are unknown due to a lack of key information regarding birth and survival rates. The U.S. Endangered Species Act prohibits the hunting of sea turtles and reduces incidental losses from activities such as shrimp trawling and development on beaches used for nesting. However, current monitoring does not provide enough information on sea turtle populations to evaluate the effectiveness of these protective measures. Sea Turtle Status and Trends reviews current methods for assessing sea turtle populations and finds that although counts of sea turtles are essential, more detailed information on sea turtle biology, such as survival rates and breeding patterns, is needed to predict and understand changes in populations in order to develop successful management and conservation plans.
Describes the physical characteristics, behavior, and habitat of the leatherback turtle and discusses some of the reasons it is in danger of extinction.
