    Most conservationists and environmentalists share this view. But what if the traditional view of ecology is wrong—what if true environmentalists should be applauding the invaders? In The New Wild, Pearce goes on a journey across six continents to rediscover what conservation in the twenty-first century should be about. Pearce explores ecosystems from remote Pacific islands to the United Kingdom, from San Francisco Bay to the Great Lakes, as he digs into questionable estimates of the cost of invader species and reveals the outdated intellectual sources of our ideas about the balance of nature. Pearce acknowledges that there are horror stories about alien species disrupting ecosystems, but most of the time, the tens of thousands of introduced species usually swiftly die out or settle down and become model eco-citizens. The case for keeping out alien species, he finds, looks increasingly flawed. As Pearce argues, mainstream environmentalists are right that we need a rewilding of the earth, but they are wrong if they imagine that we can achieve that by reengineering ecosystems. Humans have changed the planet too much, and nature never goes backward. But a growing group of scientists is taking a fresh look at how species interact in the wild. According to these new ecologists, we should applaud the dynamism of alien species and the novel ecosystems they create. In an era of climate change and widespread ecological damage, it is absolutely crucial that we find ways to help nature regenerate. Embracing the new ecology, Pearce shows us, is our best chance. To be an environmentalist in the twenty-first century means celebrating nature’s wildness and capacity for change.

    Once you own a flash, though, you'll have a lot of questions about how to get it to create the light you need—questions about camera and flash settings, questions about direction, quality, and quantity of light. And in addition to knowing how to use your flash, you need to know which modifiers and triggers you might need, and you need to learn use them quickly.That’s why this book was created: to quickly get you to the technique, the setting, or exactly the right thing you need to do right now to improve your work.Here’s how it works: When you need to know how to do a particular thing, you turn to the chapter where it would be found, find the thing you need to do (it’s easy, each page covers just one single topic), and Scott tells you exactly how to do it just like he was sitting there beside you, using the same casual style as if he were telling a friend. That way, you get back to shooting fast. This isn’t a book of theory, full of confusing jargon and detailed multi-step concepts. This is a book on which button to click, which setting to use, and exactly how and when to use it, so you’re never “stuck” wondering how to use your flash again. This will be your “go to” book that sits within reach any time you’re shooting with flash, and you are going to love having this type of help right at your fingertips.

    From Hindu mythology to Aztec sacrifices, butterflies have served as a metaphor for resurrection and transformation. Even during World War II, children in a Polish death camp scratched hundreds of butterflies onto the walls of their barracks. But as Russell points out in this rich and lyrical meditation, butterflies are above all objects of obsession. From the beastly horned caterpillar, whose blood helps it count time, to the peacock butterfly, with wings that hiss like a snake, Russell traces the butterflies through their life cycles, exploring the creatures' own obsessions with eating, mating, and migrating. In this way, she reveals the logic behind our endless fascination with butterflies as well as the driving passion of such legendary collectors as the tragic Eleanor Glanville, whose children declared her mad because of her compulsive butterfly collecting, and the brilliant Henry Walter Bates, whose collections from the Amazon in 1858 helped develop his theory of mimicry in nature. Russell also takes us inside some of the world's most prestigious natural history museums, where scientists painstakingly catalogue and categorize new species of Lepidoptera, hoping to shed light on insect genetics and evolution. A luminous journey through an exotic world of obsession and strange beauty, this is a book to be treasured by anyone who's ever watched a butterfly mid-flight and thought, as Russell has, "I've entered another dimension."

    But that's not all -- food would be in much shorter supply, and available in much less variety. While the media focuses on colony-collapse disorder and the threats to honey bees specifically, the real danger is much greater: all bees are at risk. And because of the integral role these insects play in the ecology of our planet, we may be at risk as well.The life of Laurence Packer, a melittologist at Toronto's York University, revolves around bees, whether he's searching for them under leaves in a South American jungle or identifying new species in the desert heat of Arizona. Packer often finds himself in exotic and even dangerous locales, risking snake bites, sunstroke, and even the ire of other scientists. Everywhere he travels, he discovers the same unsettling trend: bees are disappearing. And since bees are responsible for up to one-third of our food supply, the consequences are frightening.

    As well as exploring how birds achieve the miracle of flight; why birds sing; what they tell us about the seasons of the year and what their presence tells us about the places they inhabit, The Meaning of Birds muses on the uses of feathers, the drama of raptors, the slaughter of pheasants, the infidelities of geese, and the strangeness of feeling sentimental about blue tits while enjoying a chicken sandwich.From the mocking-birds of the Galapagos who guided Charles Darwin toward his evolutionary theory, to the changing patterns of migration that alert us to the reality of contemporary climate change, Simon Barnes explores both the intrinsic wonder of what it is to be a bird—and the myriad ways in which birds can help us understand the meaning of life.

    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

    This friendly, relatable book is a celebration of the art, science, and delights of bird-watching.How to Know the Birds introduces a new, holistic approach to bird-watching, by noting how behaviors, settings, and seasonal cycles connect with shape, song, color, gender, age distinctions, and other features traditionally used to identify species. With short essays on 200 observable species, expert author Ted Floyd guides us through a year of becoming a better birder, each species representing another useful lesson: from explaining scientific nomenclature to noting how plumage changes with age, from chronicling migration patterns to noting hatchling habits. Dozens of endearing pencil sketches accompany Floyd's charming prose, making this book a unique blend of narrative and field guide. A pleasure for birders of all ages, this witty book promises solid lessons for the beginner and smiles of recognition for the seasoned nature lover.
