Sea turtles have existed for millions of years, making them fascinating subjects of study. In the last 20 years, the science of sea turtle biology has expanded at an exponential rate, leading to major advances in many areas. This book synthesizes the results of these advances and focuses on how these endangered marine reptiles operate in, adapt to, and are dependent upon particular features of their marine environment. New technology in data gathering, such as DNA analyses, remote sensing, and physiological monitoring techniques, has led to a much greater understanding of the biology of the sea turtle at all stages of their life history.Areas of advancement discussed in "The Biology of Sea Turtles" include: Population genetics and phylogeny; Sensory biology; Migration and orientation hatchling behavior; Age and growth; Reproduction and endocrinology sex determination; Diving physiology; and, Osmoregulation. The book also addresses the endangered status of sea turtles and deals with threats to their survival posed by man-made changes to ocean and coastal zones. The first book of its kind, "The Biology of Sea Turtles" fills a substantial void in the literature, and will be of great value and interest to marine biologists, environmentalists, and conservationists.
