The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today.

    In Dark Banquet, zoologist Bill Schutt takes readers on an entertaining voyage into the world of some of nature’s strangest creatures—the sanguivores. Using a sharp eye and mordant wit, Schutt makes a remarkably persuasive case that vampire bats, leeches, ticks, bed bugs, and other vampires are as deserving of our curiosity as warmer and fuzzier species are—and that many of them are even ­worthy of conservation.Schutt takes us from rural Trinidad to the jungles of Brazil to learn about some of the most reviled, misunderstood, and marvelously evolved animals on our planet: vampire bats. Only recently has fact begun to disentangle itself from fiction concerning these remarkable animals, and Schutt delves into the myths and misconceptions surrounding them. Examining the substance that sustains nature’s vampires, Schutt reveals just how little we actually knew about blood until well into the twentieth century. We revisit George Washington on his deathbed to learn how ideas about blood and the supposedly therapeutic value of bloodletting, first devised by the ancient Egyptians and Greeks, survived into relatively modern times. Schutt also tracks the history of medicinal leech use. Once employed by the tens of millions to drain perceived excesses of blood, today the market for these ancient creatures is booming once again—but for very different reasons.Among the other blood feeders we meet in these pages are bed bugs, or “ninja insects,” which are making a creepy resurgence in posh hotels and well-kept homes near you. In addition, Dark Banquet details our dangerous and sometimes deadly encounters with ticks, chiggers, and mites (the ­latter implicated in Colony Collapse Disorder—currently devastating honey bees worldwide). Then there are the truly weird—vampire finches. And if you thought piranha were scary, some people believe that the candiru (or willy fish) is the best reason to avoid swimming in the Amazon.Enlightening, alarming, and appealing to our delight in the bizarre, Dark Banquet peers into a part of the natural world to which we are, through our blood, inextricably linked.From the Hardcover edition.

    But as Ocean Guardian founder William McKeever reveals, sharks are evolutionary marvels essential to maintaining a balanced ecosystem. We can learn much from sharks, he argues, and our knowledge about them continues to grow. The first book to reveal in full the hidden lives of sharks, Emperors of the Deep examines four species—Mako, Tiger, Hammerhead, and Great White—as never before, and includes fascinating details such as:Sharks are 50-million years older than trees;Sharks have survived five extinction level events, including the one that killed off the dinosaurs;Sharks have electroreception, a sixth-sense that lets them pick up on electric fields generated by living things;Sharks can dive 4,000 feet below the surface;Sharks account for only 6 human fatalities per year, while humans kill 100 million sharks per year.McKeever goes back through time to probe the shark’s pre-historic secrets and how it has become the world’s most feared and most misunderstood predator, and takes us on a pulse-pounding tour around the world and deep under the water’s surface, from the frigid waters of the Arctic Circle to the coral reefs of the tropical Central Pacific, to see sharks up close in their natural habitat. He also interviews ecologists, conservationists, and world-renowned shark experts, including the founders of Greenpeace’s Rainbow Warrior, the head of the Massachusetts Shark Research Program, and the self-professed “last great shark hunter.”At once a deep-dive into the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates this wild species that hold the key to unlocking the mysteries of the ocean—if we can prevent their extinction from climate change and human hunters.

    But one of the challenges of a standard low-carb, high-fat keto diet is that it can be hard to stick to.Dr Michael Mosley's Fast 800 Keto is both more effective than a conventional keto regime, and healthier and more sustainable. The secret to this new approach is that it combines keto with intermittent fasting, which means you go into ketosis faster, while also being able to enjoy delicious Mediterranean-style food.Based on the latest dietary science, this book presents a simple, highly flexible three-step programme to ensure you lose weight rapidly and safely, while preserving your metabolic rate. It includes protein-rich, low-carb recipes and easy-to- follow menus from bestselling author Dr Clare Bailey, and all the other tools you need to shift stubborn fat and transform your health for good.

    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.

    On her travels she has witnessed some of the daunting and brutal challenges our ancestors had to face: mountains, deserts, oceans, changing climates, terrifying giant beasts and volcanoes. But she discovers that perhaps the most serious threat of all came from other humans. When our ancestors set out from Africa there were already two other species of human on the planet: Neanderthal in Europe and Homo erectus in Asia. Both (contrary to popular perception) were intelligent, adept at making tools and weapons and were long adapted to their environments. So, Alice asks, why did only Homo sapiens survive? Part detective story, part travelogue, and drawing on the latest genetic and archaeological discoveries, Alice examines how our ancestors evolved physically in response to these challenges, finding out how our colour, shape, size, diet, disease resistance and even athletic ability have been shaped by the range of environments that our ancestors had to survive. She also relates how astonishingly closely related we all are.

    Illustrated with hundreds of his original photographs, Tracking & the Art of Seeing provides complete information on the behavior and habitat of over 50 animal species and shows you how to identify animals by their tracks, tail patterns, droppings, dens, scratches and other signs.

    Since then, deformed frogs have been turning up in lakes around the world. Written by the only journalist granted access to secret hot spots where these deformed frogs are tested, and brainstorming sessions among the researchers, this compelling, fast-paced narrative is the first to offer a complete picture of what is quite possibly a global catastrophe in the making.

    Nancy Butcher has gathered together some of the most unusual natural cures that have been proven effective today, and even throws in some unbelievable and-thankfully-abandoned therapies from times past.Filled with case histories of unique illnesses, historic documentation of strange medical practices, and the author's own insightful commentary, this book explains not only how to cure headaches, sleep better, and improve your sex life, but also that people with Cotard's syndrome actually believe they are dead.

    Millions of children are busy with projects to save the Earth. But we all would be more effective at resolving today's pressing environmental issues if we had a clearer understanding of the ecological principles behind them. With this lively guide to the essentials of ecology, Ernest Callenbach provides a pocket-sized introduction to the wonderful complexity of life on Earth—and our part in it.Callenbach uses everyday, nontechnical language to explain sixty basic ecological concepts. These brief, information-packed entries are arranged alphabetically and amply cross-referenced. Thus the reader can move freely around a dynamic network of ideas, gaining easy access to the new thinking that scientists, environmentalists, politicians, government officials, business people, and concerned citizens everywhere are using to seek a sustainable future for humanity.As timely as today's news, Ecology includes current findings on the microscopic beings that first made plant and animal life possible and now regulate global temperature and oxygen levels—a dramatic new story of the intricate interconnections of all life on Earth. Finally we have a book that equips us to take informed personal and political action with the ecological wisdom needed for the twenty-first century.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.
