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:
o Population genetics and phylogeny
o Sensory biology
o Migration and orientation hatchling behavior
o Age and growth
o Reproduction and endocrinology sex determination
o Diving physiology
o 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.

You want to show the world the real you. But sometimes you're not sure who the real you really is. (Here's help.)
Being a teen girl isn't easy. The pressures, the frustrations, the fears. Some days you just want to disappear. But a voice inside keeps whispering that you were created for an amazing life. And you want it. You long to become the kind of beautiful young woman who can confidently tell the world...
"This is me "
So where do you start? Maybe with a helpful handbook to the truth about you.

For your personal journey from here to extraordinary, "This Is Me "is the travel companion every girl needs.

What Do You Call Cheese that Isn't Yours?
One-liners. The jokes are known for little more than eliciting a groan or two from you. But since Jeffery Dean came up with this handy booklet for teens, one-liners have become a handy tool. These quotes, questions, and statements will cut to the chase and spark the, "Hmmm...I never thought of that before!" section of your gray matter. Some are funny, some are convicting. Each is thought-provoking. Bring a little simplicity back to your complicated life. Don't expect the world's problems to be solved or all of your personal troubles to immediately go away. But do look for plenty of food for thought about what really matters. By the way, the cheese that doesn't belong to you? It's nacho cheese. (A cheesier one-liner than anything you'll find in this book.)
Think.
"Do you live life looking back or looking forward?"
But not too hard.
"God has your name tattooed on His heart."
"Tattoos are permanent."
Funny and deep. Surprising and smart. One-liners to put you on top of your day.
