By some estimates, we may already have lost almost half of the songbirds that filled the skies only forty years ago. Renowned biologist Bridget Stutchbury convincingly argues that songbirds truly are the "canaries in the coal mine"--except the coal mine looks a lot like Earth and we are the hapless excavators.Following the birds on their six-thousand-mile migratory journey, Stutchbury leads us on an ecological field trip to explore firsthand the major threats to songbirds: pesticides, still a major concern decades after Rachel Carson first raised the alarm; the destruction of vital habitat, from the boreal forests of Canada to the diminishing continuous forests of the United States to the grasslands of Argentina; coffee plantations, which push birds out of their forest refuges so we can have our morning fix; the bright lights and structures in our cities, which prove a minefield for migrating birds; and global warming. We could well wake up in the near future and hear no songbirds singing. But we won't just be missing their cheery calls, we'll be missing a vital part of our ecosystem. Without songbirds, our forests would face uncontrolled insect infestations, and our trees, flowers, and gardens would lose a crucial element in their reproductive cycle. As Stutchbury shows, saving songbirds means protecting our ecosystem and ultimately ourselves.Some of the threats to songbirds: - The U.S. annually uses 4-5 million pounds of active ingredient acephate, an insecticide that, even in small quantities, throws off the navigation systems of White-throated sparrows and other songbirds, making them unable to tell north from south. - The U.S. Fish and Wildlife Service conservatively estimated that 4-5 million birds are killed by crashing into communication towers each year.- A Michigan study found that 600 domestic cats killed more than 6,000 birds during a typical 10-week breeding season.

    Krause is a pioneer in the revolutionary new science of archaeogenetics, archaeology augmented by revolutionary DNA sequencing technology, which has allowed scientists to uncover a new version of human history reaching back more than 100,000 years. Using this technology to re-examine human bones from the distant past, Krause has been able to map not only the genetic profiles of the dead, but also their ancient journeys.In this concise narrative he tells us their long-forgotten stories of migration and intersection. It's well known that many human populations carry genetic material from Neanderthals; but, as Krause and his colleagues discovered, we also share DNA with a newly uncovered human form, the Denisovans. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. The farmer DNA is one of the core genetic components of contemporary Europeans and European Americans. Though the first people to cross into North and South America have long been assumed to be primarily of East Asian descent, we now know that they also share DNA with contemporary Europeans and European Americans. Genetics has an unfortunate history of smuggling in racist ideologies, but our most cutting-edge science tells us that genetic categories in no way reflect national borders.Krause vividly introduces us to prehistoric cultures such as the Aurignacians, innovative artisans who carved animals, people, and even flutes from bird bones more than 40,000 years ago; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt; and the Gravettians, big-game hunters who were Europe's most successful early settlers until they perished in the ice age. This informed retelling of the human epic confirms that immigration and genetic mingling have always defined our species and that who we are is a question of culture not genetics.

    Now he shares that information, integrating an explanation for the identification process with many painted and drawn images of details (such as a feather) or concepts.

      Every spring, billions of birds sweep north, driven by ancient instincts to return to their breeding grounds. This vast parade often goes unnoticed, except in a few places where these small travelers concentrate in large numbers. One such place is along Lake Erie in northwestern Ohio. There, the peak of spring migration is so spectacular that it attracts bird watchers from around the globe, culminating in one of the world’s biggest birding festivals.     Millions of winged migrants pass through the region, some traveling thousands of miles, performing epic feats of endurance and navigating with stunning accuracy. Now climate change threatens to disrupt patterns of migration and the delicate balance between birds, seasons, and habitats. But wind farms—popular as green energy sources—can be disastrous for birds if built in the wrong places. This is a fascinating and urgent study of the complex issues that affect bird migration.

    This latest book gives you a precise regimen for self-treatment along with extensive information on other resources now available to you.

    With the assistance of a co-author, this popular student textbook has now been updated to include techniques such as membrane chromatography, aqueous phase partitioning, engineering recombinant proteins for purification and due to the rapid advances in bioinformatics/proteomics a discussion of the analysis of complex protein mixtures by 2D-electrophoresis and RPHPLC prior to sequencing by mass spectroscopy. Written with the student firmly in mind, no previous knowledge of biochemistry, and little of chemistry, is assumed. It is intended to provide an introduction to enzymology, and a balanced account of all the various theoretical and applied aspects of the subject which are likely to be included in a course.

    David Owen traces all that water from the Colorado's headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.–Mexico border where the river runs dry. Water problems in the western United States can seem tantalizingly easy to solve: just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on.The story Owen tells in Where the Water Goes is crucial to our future: how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert, and the disastrous consequences we face when any part of this tenuous system fails.

    This is the funny, poignant story of their two decades together.On Valentine's Day 1985, biologist Stacey O'Brien first met a four-day-old baby barn owl -- a fateful encounter that would turn into an astonishing 19-year saga. With nerve damage in one wing, the owlet's ability to fly was forever compromised, and he had no hope of surviving on his own in the wild. O'Brien, a young assistant in the owl laboratory at Caltech, was immediately smitten, promising to care for the helpless owlet and give him a permanent home. Wesley the Owl is the funny, poignant story of their dramatic two decades together. With both a tender heart and a scientist's eye, O'Brien studied Wesley's strange habits intensively and first-hand -- and provided a mice-only diet that required her to buy the rodents in bulk (28,000 over the owl's lifetime). As Wesley grew, she snapped photos of him at every stage like any proud parent, recording his life from a helpless ball of fuzz to a playful, clumsy adolescent to a gorgeous, gold-and-white, macho adult owl with a heart-shaped face and an outsize personality that belied his 18-inch stature. Stacey and Wesley's bond deepened as she discovered Wesley's individual personality, subtle emotions, and playful nature that could also turn fiercely loyal and protective -- though she could have done without Wesley's driving away her would-be human suitors! O'Brien also brings us inside the prestigious research community, a kind of scientific Hogwarts where resident owls sometimes flew freely from office to office and eccentric, brilliant scientists were extraordinarily committed to studying and helping animals; all of them were changed by the animal they loved. As O'Brien gets close to Wesley, she makes important discoveries about owl behavior, intelligence, and communication, coining the term "The Way of the Owl" to describe his inclinations: he did not tolerate lies, held her to her promises, and provided unconditional love, though he was not beyond an occasional sulk. When O'Brien develops her own life-threatening illness, the biologist who saved the life of a helpless baby bird is herself rescued from death by the insistent love and courage of this wild animal. Enhanced by wonderful photos, Wesley the Owl is a thoroughly engaging, heartwarming, often funny story of a complex, emotional, non-human being capable of reason, play, and, most important, love and loyalty. It is sure to be cherished by animal lovers everywhere.

    Baker set out to track the daily comings and goings of a pair of peregrine falcons across the flat fen lands of eastern England. He followed the birds obsessively, observing them in the air and on the ground, in pursuit of their prey, making a kill, eating, and at rest, activities he describes with an extraordinary fusion of precision and poetry. And as he continued his mysterious private quest, his sense of human self slowly dissolved, to be replaced with the alien and implacable consciousness of a hawk.It is this extraordinary metamorphosis, magical and terrifying, that these beautifully written pages record.
