As she grows into adulthood, only a few of her eggs mature, are released into the oviduct, and are fertilized by sperm stored from copulation that took place days or weeks earlier. Within a matter of hours, the fragile yolk is surrounded by albumen and the whole is gradually encased within a turquoise jewel of a shell. Soon afterward the fully formed egg is expelled onto a bare rocky ledge, where it will be incubated for four weeks before another chick emerges and the life cycle begins again. The Most Perfect Thing is about how eggs in general are made, fertilized, developed, and hatched. The eggs of most birds spend just 24 hours in the oviduct; however, that journey takes 48 hours in cuckoos, which surreptitiously lay their eggs in the nests of other birds. From the earliest times, the study of birds' ovaries and ova (eggs) played a vital role in the quest to unravel the mysteries of fertilization and embryo development in humans. Birkhead uses birds' eggs as wondrous portals into natural history, enlivened by the stories of naturalists and scientists, including Birkhead and his students, whose discoveries have advanced current scientific knowledge of reproduction.

    The pages take the reader on a wild narrative ride through the world of squid science and adventure, along the way addressing some riddles about what intelligence is, and what monsters lie in the deep. In addition to squid, both giant and otherwise, Kraken examines other equally enthralling cephalopods, including the octopus and the cuttlefish, and explores their otherworldly abilities, such as camouflage and bioluminescence. Accessible and entertaining, Kraken is also the first substantial volume on the subject in more than a decade and a must for fans of popular science.

    An exhilarating account of Sapolsky’s twenty-one-year study of a troop of rambunctious baboons in Kenya, A Primate’s Memoir interweaves serious scientific observations with wry commentary about the challenges and pleasures of living in the wilds of the Serengeti — for man and beast alike. Over two decades, Sapolsky survives culinary atrocities, gunpoint encounters, and a surreal kidnapping, while witnessing the encroachment of the tourist mentality on the farthest vestiges of unspoiled Africa. As he conducts unprecedented physiological research on wild primates, he becomes evermore enamored of his subjects — unique and compelling characters in their own right — and he returns to them summer after summer, until tragedy finally prevents him.By turns hilarious and poignant, A Primate’s Memoir is a magnum opus from one of our foremost science writers.

    In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone. Yet, as we obsess over sterilizing our homes and separating our spaces from nature, we are unwittingly cultivating an entirely new playground for evolution. These changes are reshaping the organisms that live with us -- prompting some to become more dangerous, while undermining those species that benefit our bodies or help us keep more threatening organisms at bay. No one who reads this engrossing, revelatory book will look at their homes in the same way again.

    While detailing this evolution, Humphries introduces us to synanthropy: The concept that animals can become dependent on humans without ceasing to be wild; they can adapt to the cityscape as if it were a field or a forest.Superdove simultaneously explores the pigeon's cultural transformation, from its life in the dovecotes of ancient Egypt to its service in the trenches of World War I, to its feats within the pigeon-racing societies of today. While the dove is traditionally recognized as a symbol of peace, the pigeon has long inspired a different sort of fetishistic devotion from breeders, eaters, and artists—and from those who recognized and exploited the pigeon's astounding abilities. Because of their fecundity, pigeons were symbols of fertility associated with Aphrodite, while their keen ability to find their way home made them ideal messengers and even pilots.Their usefulness largely forgotten, today's pigeons have become as ubiquitous and reviled as rats. But Superdove reveals something more surprising: By using pigeons for our own purposes, we humans have changed their evolution. And in doing so, we have helped make pigeons the ideal city dwellers they are today. In the tradition of Rats, the book that made its namesake rodents famous, Superdove is the fascinating story of the pigeon's journey from the wild to the city—the home they'll never leave.

    Last Stand gives us a new, unexpected lens through which to view a previously unsung hero of conservation and offers prescriptions for the future of conservation.

    Legendary marine scientist Sylvia Earle portrays a planet teetering on the brink of irreversible environmental crisis.In recent decades we’ve learned more about the ocean than in all previous human history combined. But, even as our knowledge has exploded, so too has our power to upset the delicate balance of this complex organism. Modern overexploitation has driven many species to the verge of extinction, from tiny but indispensable biota to magnificent creatures like tuna, swordfish, and great whales. Since the mid-20th century about half our coral reefs have died or suffered sharp decline; hundreds of oxygen-deprived "dead zones" blight our coastal waters; and toxic pollutants afflict every level of the food chain.Fortunately, there is reason for hope, but what we do—or fail to do—in the next ten years may well resonate for the next ten thousand. The ultimate goal, Earle argues passionately and persuasively, is to find responsible, renewable strategies that safeguard the natural systems that sustain us. The first step is to understand and act upon the wise message of this accessible, insightful, and compelling book.

    We have formed a global civilisation of unprecedented might, driven forward by the power of our minds—a civilisation which is transforming our Earth. We are masters of technology, and of comprehension, but it's what we believe that may, from now on, determine our fate.Tim Flannery's first major book since The Weather Makers charts the history of life on our planet. Here on Earth, which draws its points of departure from Darwin and Wallace, Lovelock and Dawkins, is an extraordinary exploration of evolution and sustainability. Our success as a species has had disastrous effects on many of the Earth's ecosystems and could lead to our downfall. But equally, Flannery argues, we are now equipped as never before to explore our true relationship with the planet on which our biological, economic and cultural futures depend. Here on Earth is not just a dazzling account of life on our planet. It will change the way you live.

    Bees are crucial to the reproduction and diversity of flowering plants, and the economic contributions of these irreplaceable insects measure in the tens of billions of dollars each year. Yet bees are dying at an alarming rate, threatening food supplies and ecosystems around the world. In this richly illustrated natural history of the bee, Noah Wilson-Rich and his team of bee experts provide a window into the vitally important role that bees play in the life of our planet.Earth is home to more than 20,000 bee species, from fluorescent-colored orchid bees and sweat bees to flower-nesting squash bees and leaf-cutter bees. This book takes an incomparable look at this astounding diversity, blending an engaging narrative with practical, hands-on discussions of such topics as beekeeping and bee health. It explores our relationship with the bee over evolutionary time, delving into how it came to be, where it stands today, and what the future holds for humanity and bees alike.Provides an accessible, illustrated look at the human-bee relationship over timeFeatures a section on beekeeping and handy go-to guides to the identification, prevention, and treatment of honey bee diseasesCovers bee evolution, ecology, genetics, and physiologyIncludes a directory of notable bee speciesPresents a holistic approach to bee health, including organic and integrated pest management techniquesShows what you can do to help bee populations

    Now, Heller chronicles this hair-raising journey, whose mission was to stop illegal whaling in the stormy, remote seas off Antarctica. 288.

    If animals could talk, we would ask them to recall their own ancestries, in particular the secrets as to how they avoided almost inevitable annihilation in the face of daily assaults by predators, climactic cataclysms, deadly infections and innate diseases.In Tears of the Cheetah, medical geneticist and conservationist Stephen J. O'Brien narrates fast-moving science adventure stories that explore the mysteries of survival among the earth's most endangered and beloved wildlife. Here we uncover the secret histories of exotic species such as Indonesian orangutans, humpback whales, and the imperiled cheetah-the world's fastest animal which nonetheless cannot escape its own genetic weaknesses.Among these genetic detective stories we also discover how the Serengeti lions have lived with FIV (the feline version of HIV), where giant pandas really come from, how bold genetic action pulled the Florida panther from the edge of extinction, how the survivors of the medieval Black Death passed on a genetic gift to their descendents, and how mapping the genome of the domestic cat solved a murder case in Canada.With each riveting account of animal resilience and adaptation, a remarkable parallel in human medicine is drawn, adding yet another rationale for species conservation-mining their genomes for cures to our own fatal diseases. Tears of the Cheetah offers a fascinating glimpse of the insight gained when geneticists venutre into the wild.

    Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can't answer that question here on earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society's most charged conflicts--whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.Charting the obsession with Dr. Frankenstein's monster and how Coleridge came to believe the whole universe was alive, Zimmer leads us all the way into the labs and minds of researchers working on engineering life from the ground up.

     From the Aztec plumed serpent to the Christian dove to Plato's vision of the human soul growing wings, religion and philosophy use birds to represent our aspirational selves. Winged creatures appear in mythology and folk tales, and in literature by writers as diverse as Ovid, Thoreau, and T. S. Eliot. They've been omens, allegories, and guides; they've been worshipped, eaten, and feared. Birds figure tellingly in the work of such nature writers as Gilbert White and Peter Matthiessen, and are synonymous with the science of Darwin.Gibson spent years collecting this gorgeously illustrated celebration of centuries of human response to the delights of the feathered tribes. The Bedside Book of Birds is for everyone who is intrigued by the artistic forms that humanity creates to represent its soul.

    Among them were Pete and Linda Dunne, who set off from there on a year-long odyssey. Dunne has poured the most remarkable stories, birds, and characters into this unforgettable book about their once-in-a-lifetime adventure.

    But was it a savage sheep killer or a shy, fussy, nocturnal feeder? And did it really drink its victims' blood? Once reviled, feared and slaughtered by government decree, the myth of the Tasmanian Tiger continues to grow. So treasured is it now, the Tasmanian Tiger has become the official logo of the island that wiped it out and a symbol of the conservation movement world-wide.A number of Australian species have miraculously reappeared after being labelled as extinct. Perhaps the Tiger is still with us. And if it's not, can it be brought back by cloning?
