These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone.What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses.Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

    Many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—build our bodies, protect our health, shape our identities, and grant us incredible abilities. In this astonishing book, Ed Yong takes us on a grand tour through our microbial partners, and introduces us to the scientists on the front lines of discovery. Yong, whose humor is as evident as his erudition, prompts us to look at ourselves and our animal companions in a new light—less as individuals and more as the interconnected, interdependent multitudes we assuredly are. The microbes in our bodies are part of our immune systems and protect us from disease. Those in cows and termites digest the plants they eat. In the deep oceans, mysterious creatures without mouths or guts depend on microbes for all their energy. Bacteria provide squids with invisibility cloaks, help beetles to bring down forests, and allow worms to cause diseases that afflict millions of people. I Contain Multitudes is the story of these extraordinary partnerships, between the creatures we are familiar with and those we are not. It reveals how we humans are disrupting these partnerships and how we might manipulate them for our own good. It will change both our view of nature and our sense of where we belong in it.

    For The Best of Gerald Durrell she has chosen evocative, quirky, engaging and humorous pieces to give a wonderful picture of how his extraordinary life unfolded. Starting with his early naturalist days and the rapid development of his passion for animals, this anthology includes writings of his collecting trips to such places as Cameroon, Argentina and Madagascar, his growing concern about the nature of zoos, the emergence of his conservation plans, and the realization of his lifelong dream, a zoo of his own, and how it became a model for the future.

    In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks readers through the astonishing and controversial process of de-extinction. From deciding which species should be restored, to sequencing their genomes, to anticipating how revived populations might be overseen in the wild, Shapiro vividly explores the extraordinary cutting-edge science that is being used--today--to resurrect the past. Journeying to far-flung Siberian locales in search of ice age bones and delving into her own research--as well as those of fellow experts such as Svante Paabo, George Church, and Craig Venter--Shapiro considers de-extinction's practical benefits and ethical challenges. Would de-extinction change the way we live? Is this really cloning? What are the costs and risks? And what is the ultimate goal?Using DNA collected from remains as a genetic blueprint, scientists aim to engineer extinct traits--traits that evolved by natural selection over thousands of years--into living organisms. But rather than viewing de-extinction as a way to restore one particular species, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. For example, elephants with genes modified to express mammoth traits could expand into the Arctic, re-establishing lost productivity to the tundra ecosystem.Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.

    Moreover, groundbreaking research on genes, and especially key families of genes such as the Homeobox genes which controlthe development of body plans, has led to radical changes in the classification of animals. In this Very Short Introduction, Peter Holland presents a cutting-edge tour of the animal kingdom, providing an authoritative summary of the modern view of animal life, its origins, and the new classificationresulting from DNA studies. Beginning with the definition of animals (not obvious in biological terms), Holland takes the reader through the revolutionary new high-level groupings of animals (phyla) based on evolutionary relationships and ancestry. Ranging from corals and sponges to nematodes, seasquirts, and vertebrates, and illuminating many key topics in zoology, this fascinating, brief overview will be of great value to all students of the life sciences as well as providing a concise summary for the interested lay reader.

    Scientist and fisherman Carl Safina takes readers on a global journey of discovery, probing for truth about the world's changing seas, deftly weaving adventure, science, and political analysis.

    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.

    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.

    Through overfishing, climate change, and ocean pollution we are disrupting the creative procreation that drives the wild abundance of life in the ocean. With wit and scientific rigor, Hardt introduces us to the researchers and innovators who study the wet and wild sex lives of ocean life and offer solutions that promote rather than prevent, successful sex in the sea. Part science, part erotica, Sex in the Sea discusses how we can shift from a prophylactic to a more propagative force for life in the ocean.

    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.

    Many people have never heard of these salt-water forests, but for those who depend on their riches, mangroves are indispensable. They are natural storm barriers, home to innumerable exotic creatures—from crabeating vipers to man-eating tigers—and provide food and livelihoods to millions of coastal dwellers. Now they are being destroyed to make way for shrimp farming and other coastal development. For those who stand in the way of these industries, the consequences can be deadly. In Let Them Eat Shrimp, Kennedy Warne takes readers into the muddy battle zone that is the mangrove forest. A tangle of snaking roots and twisted trunks, mangroves are often dismissed as foul wastelands. In fact, they are supermarkets of the sea, providing shellfish, crabs, honey, timber, and charcoal to coastal communities from Florida to South America to New Zealand. Generations have built their lives around mangroves and consider these swamps sacred. To shrimp farmers and land developers, mangroves simply represent a good investment. The tidal land on which they stand often has no title, so with a nod and wink from a compliant official, it can be turned from a public resource to a private possession. The forests are bulldozed, their traditional users dispossessed. The true price of shrimp farming and other coastal development has gone largely unheralded in the U.S. media. A longtime journalist, Warne now captures the insatiability of these industries and the magic of the mangroves. His vivid account will make every reader pause before ordering the shrimp.
