    So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the “eel question”: Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even today, in an age of advanced science, no one has ever seen eels mating or giving birth, and we still don’t understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery.Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson writes a book about this unusual animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel’s point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea.Blending memoir and nature writing, Svensson’s journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death.

    But in recent decades, these claims have eroded, or even been disproven outright, by a revolution in the study of animal cognition. Take the way octopuses use coconut shells as tools; elephants that classify humans by age, gender, and language; or Ayumu, the young male chimpanzee at Kyoto University whose flash memory puts that of humans to shame. Based on research involving crows, dolphins, parrots, sheep, wasps, bats, whales, and of course chimpanzees and bonobos, Frans de Waal explores both the scope and the depth of animal intelligence. He offers a firsthand account of how science has stood traditional behaviorism on its head by revealing how smart animals really are, and how we’ve underestimated their abilities for too long.People often assume a cognitive ladder, from lower to higher forms, with our own intelligence at the top. But what if it is more like a bush, with cognition taking different forms that are often incomparable to ours? Would you presume yourself dumber than a squirrel because you’re less adept at recalling the locations of hundreds of buried acorns? Or would you judge your perception of your surroundings as more sophisticated than that of a echolocating bat? De Waal reviews the rise and fall of the mechanistic view of animals and opens our minds to the idea that animal minds are far more intricate and complex than we have assumed. De Waal’s landmark work will convince you to rethink everything you thought you knew about animal—and human—intelligence.

    Most of Earth’s oxygen is produced by phytoplankton in the sea. These humble, one-celled organisms, rather than the spectacular rain forests, are the true lungs of the planet.• Climate control. Our climate is regulated by the ocean’s currents, winds, and water-cycle activity.Sea Sick is the first book to examine the current state of the world’s oceans — the great unexamined ecological crisis of the planet — and the fact that we are altering everything about them; temperature, salinity, acidity, ice cover, volume, circulation, and, of course, the life within them.Alanna Mitchell joins the crews of leading scientists in nine of the global ocean’s hotspots to see firsthand what is really happening around the world. Whether it’s the impact of coral reef bleaching, the puzzle of the oxygen-less dead zones such as the one in the Gulf of Mexico, or the shocking implications of the changing Ph balance of the sea, Mitchell explains the science behind the story to create an engaging, accessible yet authoritative account.From the Hardcover edition.

    For millions, the Galápagos Islands represent nature at its most unspoiled, an inviolate place famed for its rare flora and fauna. But soon today’s 30,000 human residents could surpass 50,000. Add invasive species, floods of tourists, and unresolved conflicts between Ecuadorian laws and local concerns, and it’s easy to see why the Galápagos were recently added to UNESCO’s World Heritage in Danger list. Each chapter in this provocative, perceptive book focuses on a specific person or group with a stake in the Galápagos’ natural resources—from tour companies whose activities are often illegal and not always green, to creationist guides who lead tours with no mention of evolution, from fishermen up in arms over lobster quotas, to modern-day pirates who poach endangered marine species. Bassett presents a perspective as readable as it is sensible. Told with wit, passion, and grace, the Galápagos story serves as a miniature model of Earth itself, a perfect example of how an environment can be destroyed-- and what is being done to preserve these islands before it's too late.

    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.

    Following the story of marine biologist and animal advocate at the Humane Society of the US, Naomi Rose, Kirby tells the gripping story of the two-decade fight against PR-savvy SeaWorld, which came to a head with the tragic death of trainer Dawn Brancheau in 2010. Kirby puts that horrific animal-on-human attack in context. Brancheau’s death was the most publicized among several brutal attacks that have occurred at Sea World and other marine mammal theme parks. Death at SeaWorld introduces real people taking part in this debate, from former trainers turned animal rights activists to the men and women that champion SeaWorld and the captivity of whales. In section two the orcas act out. And as the story progresses and orca attacks on trainers become increasingly violent, the warnings of Naomi Rose and other scientists fall on deaf ears, only to be realized with the death of Dawn Brancheau. Finally he covers the media backlash, the eyewitnesses who come forward to challenge SeaWorld’s glossy image, and the groundbreaking OSHA case that challenges the very idea of keeping killer whales in captivity and may spell the end of having trainers in the water with the ocean’s top predators.

    He began his career making films for the TV series "Survival," which started wildlife film-making as we know it, and is responsible for numerous groundbreaking documentaries and natural history discoveries -- from being the first person to film hippos and crocodiles underwater and the wildebeest migrating to observing that hyenas hunt. His friends and colleagues have included George and Joy Adamson and David Attenborough; he showed Dian Fossey her first mountain gorilla. His wife and long-term collaborator was Joan Root, who was tragically murdered in 2006 in retaliation for her environmental campaigning in Kenya. In "Ivory, Apes & Peacocks," Alan tells the story of his life's work, from his arrival in Kenya as a young boy (furious at having to leave behind Britain's birds) to his game-changing films, which looked at whole ecosystems (baobab trees, termite mounds) rather than the Big Five animals. Along the way we encounter Sally the pet hippo and Emily the house-proud chimp as well leopard and snake bites, ballooning adventures and amphibious cars. In this extraordinary memoir we look at Africa's wonders through the eyes of a visionary, live through hair-raising adventure and personal tragedy and also bear witness to a natural world now largely lost from view.

    Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites--from New Jersey's Cape May to California's Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away.Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species from the various angles that they are seen.Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail--the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification are discussed, including plumage, shape, and flight style traits.For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky matches the one in the guide, Hawks from Every Angle--distilling an expert's years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species--is quite simply a must.Key Features? The essential new approach to identifying hawks in flight Innovative, accurate, and field-tested identification traits for each species 339 color photos on 68 color plates, 32 black & white photos Compares and contrasts species easily confused with one another, and provides the pictures (and words) needed for identification in the field Covers in detail 19 species common to migration sites throughout the North America Discusses light conditions, how molt can alter the shape of a bird, aberrant plumages, and migration seasons and sites User-friendly format

    facilities. For Hargrove, becoming an orca trainer fulfilled a childhood dream. However, as his experience with the whales deepened, Hargrove came to doubt that their needs could ever be met in captivity. When two fellow trainers were killed by orcas in marine parks, Hargrove decided that SeaWorld's wildly popular programs were both detrimental to the whales and ultimately unsafe for trainers.After leaving SeaWorld, Hargrove became one of the stars of the controversial documentary Blackfish. The outcry over the treatment of SeaWorld's orca has now expanded beyond the outlines sketched by the award-winning documentary, with Hargrove contributing his expertise to an advocacy movement that is convincing both federal and state governments to act.In Beneath the Surface, Hargrove paints a compelling portrait of these highly intelligent and social creatures, including his favorite whales Takara and her mother Kasatka, two of the most dominant orcas in SeaWorld. And he includes vibrant descriptions of the lives of orcas in the wild, contrasting their freedom in the ocean with their lives in SeaWorld.Hargrove's journey is one that humanity has just begun to take-toward the realization that the relationship between the human and animal worlds must be radically rethought.

    Throughout these adventures, Rinella found himself contemplating his own place among the 14,000 years’ worth of buffalo hunters in North America, as well as the buffalo’s place in the American experience. At the time of the Revolutionary War, North America was home to approximately 40 million buffalo, the largest herd of big mammals on the planet, but by the mid-1890s only a few hundred remained. Now that the buffalo is on the verge of a dramatic ecological recovery across the West, Americans are faced with the challenge of how, and if, we can dare to share our land with a beast that is the embodiment of the American wilderness. American Buffalo is a narrative tale of Rinella’s hunt. But beyond that, it is the story of the many ways in which the buffalo has shaped our national identity. Rinella takes us across the continent in search of the buffalo’s past, present, and future: to the Bering Land Bridge, where scientists search for buffalo bones amid artifacts of the New World’s earliest human inhabitants; to buffalo jumps where Native Americans once ran buffalo over cliffs by the thousands; to the Detroit Carbon works, a “bone charcoal” plant that made fortunes in the late 1800s by turning millions of tons of buffalo bones into bone meal, black dye, and fine china; and even to an abattoir turned fashion mecca in Manhattan’s Meatpacking District, where a depressed buffalo named Black Diamond met his fate after serving as the model for the American nickel. Rinella’s erudition and exuberance, combined with his gift for storytelling, make him the perfect guide for a book that combines outdoor adventure with a quirky blend of facts and observations about history, biology, and the natural world. Both a captivating narrative and a book of environmental and historical significance, American Buffalo tells us as much about ourselves as Americans as it does about the creature who perhaps best of all embodies the American ethos.
