Her fascinating and wide-ranging work provides clear explanations of the science surrounding keystone predators and considers how this notion can help provide practical solutions for restoring ecosystem health and functioning.Eisenberg examines both general concepts and specific issues, sharing accounts from her own fieldwork to illustrate and bring to life the ideas she presents. She considers how resource managers can use knowledge about trophic cascades to guide recovery efforts, including how this science can be applied to move forward the bold vision of rewilding the North American continent. In the end, the author provides her own recommendations for local and landscape-scale applications of what has been learned about interactive food webs.At their most fundamental level, trophic cascades are powerful stories about ecosystem processes of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients. The Wolf’s Tooth is the first book to focus on the vital connection between trophic cascades and restoring biodiversity and habitats, and to do so in a way that is accessible to a diverse readership.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    Unlike the rest of the world's archipelagoes, it still has 95 percent of its prehuman quota of species. Wildlife of the Galapagos is the most superbly illustrated and comprehensive identification guide ever to the natural splendor of these incomparable islands--islands today threatened by alien species and diseases that have diminished but not destroyed what so enchanted Darwin on his arrival there in 1835. Covering over 200 commonly seen birds, mammals, reptiles, invertebrates, and plants, it reveals the archipelago's striking beauty through more than 400 color photographs, maps, and drawings and well-written, informative text. While the Galapagos Giant Tortoise, the Galapagos Sea Lion, and the Flightless Cormorant are recognized the world over, these thirty-three islands--in the Pacific over 600 miles from mainland Ecuador--are home to many more unique but less famous species. Here, reptiles well outnumber mammals, for they were much better at drifting far from a continent the archipelago was never connected with; the largest native land mammals are rice rats. The islands' sixty resident bird species include the only penguin to breed entirely in the tropics and to inhabit the Northern Hemisphere. There is a section offering tips on photography in the Equatorial sunlight, and maps of visitors' sites as well as information on the archipelago's history, climate, geology, and conservation. Wildlife of the Galapagos is the perfect companion for anyone who wants to know what so delighted Darwin. Covers over 200 commonly seen species including birds, mammals, reptiles, invertebrates, plants, and coastal and marine life Illustrated with over 400 color photographs, maps, and drawings; includes maps of visitors' sites Written by wildlife experts with extensive knowledge of the area Includes information on the history, climate, geology, and conservation of the islands The most complete identification guide to the wildlife of the Galapagos

    In The Perfect Protein, Andy Sharpless maintains that protecting wild seafood can help combat both issues, because seafood is the healthiest, cheapest, most environmentally friendly source of protein on earth. While the conservation community has taken a simplistic, save-the-whales approach when it comes to oceans, Sharpless contends that we must save the world's seafood not just to protect marine life and biodiversity but to stave off the coming humanitarian crisis.With high demand for predator species like tuna and salmon, wealthy nations like the U.S. convert "reduction" species such as anchovies, mackerel, and sardines into feed for salmon and other farmed animals—even though these overlooked fish are packed with health-boosting Omega-3 fatty acids and could feed millions. By establishing science-based quotas, protecting wild habitats, and reducing bycatch (and treating anchovies and their like as food, not feed), Sharpless believes that effective ocean stewardship can put healthy, sustainable seafood on the table forever. To that end, Oceana has tapped 20-plus chefs, including Mario Batali, Eric Ripert, and Jose Andres for recipes that give us all a role to play in this revolutionary mission: to save the fish so that we can eat more fish.

    It floats like a jewel in the inky black void. The reflection of the suns light from the vast expanse of water covering its surface creates its gem-like blue colour. In the entire solar system Earth is the only planet that has water in its liquid form in such quantities. Scientists have calculated that 70% of our planet is covered by water; small wonder then that humans have always been so fascinated by the oceans and what lies beneath. Today while we still have so much more of the ocean realm to uncover we have discovered enough to know that beneath the waves lies a vast treasure-trove of rich and diverse life. The Blue Planet leads us on a voyage of exploration from the coasts, the very edges of the oceans, to the deep where weird and monstrous fish lurk in a world of perpetual darkness. Along the way we meet a host of wonderful creatures from tiny copepods to majestic blue whales, from the grotesque hairy anglerfish, to the amazing tripod fish that stands on 3 delicate legs waiting to snap up unsuspecting prey. With a foreword by David Attenborough and 400 colour photos The Blue Planet is the first complete and comprehensive portrait of the whole ocean system.

    Arguing that the Barrier Reef is a product of human as much as natural history, created by minds as well as corals, McCalman describes encounters between peoples and places, ideas and environments, over the past two centuries and more.Where today the Reef is known for its astonishing underwater beauty and diversity, once it was notorious for the shipwrecks in its treacherous waters. Navigators struggled to chart a safe passage through, and scientists later theorised about the creation of this massive structure - the largest marine environment on the planet. Quixotic individuals spent years sailing the globe for an answer, and the fiery debate between Darwinists and creationists caught the world's attention. Then came successive waves of resource hunters and exploiters, followed by beachcombers and artists who fought to stop them, and the marine specialists who first became aware of the threats to the Reef's survival.In between, the Indigenous peoples of the Reef gave succour to castaways like Eliza Fraser, and were then vilified for it. Other survivors of shipwrecks lived for years with the clans of the region, were adopted by them and taught their traditional ways of life.The first social, cultural and environmental history to be written of the Great Barrier Reef, The Reef is an effortlessly readable and often moving story of one of the seven natural wonders of the world.

    It's a watery force connected to the earth, climate control and so to the eventual fate of the human race.Whitty's thirty-year career as a documentary filmmaker and diver has given her sustained access to the scientists dedicated to the study of an astonishing range of ocean life, from the physiology of extremophile life forms to the strategies of nesting seabirds to the ecology of whale falls (what happens upon the death of a behemoth).No stranger to extreme adventure, Whitty travels the oceanside and underwater world from the Sea of Cortez to Newfoundland to Antarctica. In the Galapagos, in one of the book's most haunting encounters, she realizes: "I am about to learn the answer to my long-standing question about what would happen to a person in the water if a whale sounded directly alongside: would she, like a person afloat beside a sinking ship, be dragged under too?" This book provides extraordinary armchair entree to gripping adventure, cutting-edge science, and an intimate understanding of our deep blue home.

    The Extreme Life of the Sea takes readers to the absolute limits of the ocean world--the fastest and deepest, the hottest and oldest creatures of the oceans. It dives into the icy Arctic and boiling hydrothermal vents--and exposes the eternal darkness of the deepest undersea trenches--to show how marine life thrives against the odds. This thrilling book brings to life the sea's most extreme species, and tells their stories as characters in the drama of the oceans. Coauthored by Stephen Palumbi, one of today's leading marine scientists, The Extreme Life of the Sea tells the unforgettable tales of some of the most marvelous life forms on Earth, and the challenges they overcome to survive. Modern science and a fluid narrative style give every reader a deep look at the lives of these species.The Extreme Life of the Sea shows you the world's oldest living species. It describes how flying fish strain to escape their predators, how predatory deep-sea fish use red searchlights only they can see to find and attack food, and how, at the end of her life, a mother octopus dedicates herself to raising her batch of young. This wide-ranging and highly accessible book also shows how ocean adaptations can inspire innovative commercial products--such as fan blades modeled on the flippers of humpback whales--and how future extremes created by human changes to the oceans might push some of these amazing species over the edge.An enhanced edition is also available and includes eleven videos.

    An evolutionary perspective forms the foundation of the entire discussion. The book begins with the natural history of the planet, considers portions of the whole in the middle chapters, and ends with another perspective of the entire planet in the concluding chapter. Its unique organization of focusing only on several key concepts in each chapter sets it apart from the competition. .

    Just as human cultures pass on languages and turns of phrase, tastes in food (and in how it is acquired), and modes of dress, could whales and dolphins have developed a culture of their very own? Unequivocally: yes. In The Cultural Lives of Whales and Dolphins, cetacean biologists Hal Whitehead, who has spent much of his life on the ocean trying to understand whales, and Luke Rendell, whose research focuses on the evolution of social learning, open an astounding porthole onto the fascinating culture beneath the waves. As Whitehead and Rendell show, cetacean culture and its transmission are shaped by a blend of adaptations, innate sociality, and the unique environment in which whales and dolphins live: a watery world in which a hundred-and-fifty-ton blue whale can move with utter grace, and where the vertical expanse is as vital, and almost as vast, as the horizontal. Drawing on their own research as well as a scientific literature as immense as the sea—including evolutionary biology, animal behavior, ecology, anthropology, psychology, and neuroscience—Whitehead and Rendell dive into realms both humbling and enlightening as they seek to define what cetacean culture is, why it exists, and what it means for the future of whales and dolphins. And, ultimately, what it means for our future, as well.

    But as the group pursues various threads of investigation—ecological and evolutionary studies of the sea, the desert, and their various species of animals and plants; the stories of local villagers; the journals of conquistadors and explorers—they recognize that the bay, spectacular and pristine though it seems, is but a ghost of what it once was. Life in the Sea of Cortez, they realize, has been reshaped by complex human ideas and decisions—the laws and economics of fishing, property, and water; the dreams of developers and the fantasies of tourists seeking the wild; even efforts to retrieve species from the brink of extinction—all of which have caused dramatic upheavals in the ecosystem. It is a painful realization, but the students discover a way forward.After weathering a hurricane and encountering a rare whale in its wake, they come to see that the bay's best chance of recovery may in fact reside in our own human stories, which can weave a compelling memory of the place. Glimpsing the intricate and ever-shifting web of human connections with the Sea of Cortez, the students comprehend anew their own place in the natural world—suspended between past and future, teetering between abundance and loss. The redemption in their difficult realization is that as they find their places in a profoundly altered environment, they also recognize their roles in the path ahead, and ultimately come to see one another, and themselves, in a new light.In Telling Our Way to the Sea, Hirsh's voice resounds with compassionate humanity, capturing the complex beauty of both the marine world he explores and the people he explores it with. Vibrantly alive with sensitivity and nuance, Telling Our Way to the Sea transcends its genre to become literature.
