Available in PDF, EPUB and Kindle. Book excerpt: The largest of all seals, elephant seals rank among the most impressive of marine mammals. They are renowned for their spectacular recovery from near-extinction at the end of the nineteenth century when seal hunters nearly eliminated the entire northern species. No other vertebrate has come so close to extinction and made such a complete recovery. The physiological extremes that elephant seals can tolerate are also remarkable: females fast for a month while lactating, and the largest breeding males fast for over one hundred days during the breeding seasons, at which times both sexes lose forty percent of their body weight. Elephant seals dive constantly during their long foraging migrations, spending more time under water than most whales and diving deeper and longer than any other marine mammal. This first book-length discussion of elephant seals brings together worldwide expertise from scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals. Essential for all marine mammalogists for its information and its methodological innovations, Elephant Seals will also illuminate current debates about species extinctions and possible means of preventing them. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology.

Book excerpt: "How did the elephant seal survive being driven to the brink of extinction in the nineteenth century? What variables determine the lifetime reproductive success of individual seals? How have elephant seals adapted to tolerate remarkable physiological extremes of nutrition, temperature, asphyxia, and pressure? Answering these questions and many more, this book is the result of the author's 50-year study of elephant seals. The chapters cover a broad range of topics including diving, feeding, migration and reproductive behavior, yielding fundamental information on general biological principles, the operation of natural selection, the evolution of social behavior, the formation of vocal dialects, colony development, and population changes over time. The book will be a valuable resource for graduate students and researchers of marine mammal behavior and reproductive life history as well as for amateur naturalists interested in these fascinating animals"--

Available in PDF, EPUB and Kindle. Book excerpt: Our world is filled with unseen wonders - the most phenomenal of which is the often hidden beauty of the diversity that surrounds us. Apart from the beauty diversity brings to our lives, it is also absolutely necessary to the sustainability of life itself. The importance of diversity is overlooked in the social realm, yet decisions made in that realm affect all of society for generations. Planners tend to ignore ecological diversity because they don't understand it. Ecological Diversity in Sustainable Development: The Vital and Forgotten Dimension makes that clear. The author tackles this difficult problem: how are we to maintain sustainable diversity in the Earth's ecosystems and our cultural systems? He provides examples of how natural and cultural diversity have been reduced by altering the linkages between climate, soil, water, air, forests, animals, and people. The book is divided into three parts. Part one examines diversity as it is found in nature, part two considers how culture affects diversity through its evolution, and part three explores the diversity of Nature as seen through culture in an attempt to guide culture toward social/environmental sustainability. Anyone who is interested in the quality of life on Earth will want this book. Maser writes in easy-to-read lucid prose, providing a holistic overview of environmental issues that 21st century decision makers must address in shaping our destiny.

Available in PDF, EPUB and Kindle. Book excerpt: Two polar explorers are out to solve a mystery: Where is their special seal, Patches? Scientists Roxanne Beltran and Patrick Robinson set off on a polar adventure, traveling to Antarctica to study the lives of Weddell seals. By finding Patches, a wily seal they’ve been tracking since its birth, they’ll be able to learn a lot about how much the seals get to eat and how many pups they raise. A Seal Named Patches takes young readers into the world at the very bottom of the globe, where they meet the extraordinary animals that live in cold, icy conditions. Through breathtaking photos and real-life stories, young readers will learn about how scientists do fieldwork, the challenges of researching animals in harsh climates, and even what it’s like to fly a helicopter over Antarctica. This engaging story will especially entertain and educate children in grades K-2 (ages 5–8.)

Available in PDF, EPUB and Kindle. Book excerpt: We all have our off days. Why should Evolution be any different? Maybe Evolution got carried away with an idea that was just a little too crazy—like having the Regal Horned Lizard defend itself by shooting three-foot streams of blood from its eyes. Or maybe Evolution ran out of steam (Memo to Evolution: The Irrawaddy Dolphin looks like a prototype that should have been left on the drawing board). Or maybe Evolution was feeling cheeky—a fish with hands? Joke’s on you, Red Handfish! Or maybe Evolution simply goofed up: How else to explain the overgrown teeth of the babirusas that curl backward over their face? Oops. Mara Grunbaum is a very smart, very funny science writer who celebrates the best—or, really, the worst—of Evolution’s blunders. Here are more than 100 outlandish mammals, reptiles, insects, fish, birds, and other creatures whose very existence leaves us shaking our heads and muttering WTF?! Ms. Grunbaum’s especially brilliant stroke is to personify Evolution as a well-meaning but somewhat oblivious experimenter whose conversations with a skeptical narrator are hilarious. For almost 4 billion years, Evolution has produced a nonstop parade of inflatable noses, bizarre genitalia, and seriously awkward necks. What a comedian!
