Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed--a toxic plant named for the sticky white substance emitted when its leaves are damaged--and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed--the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers.Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.

    She had no intention of staying long; she simply wanted to see if the rumors were true. That initial trip changed Smolker’s life; it commenced a fifteen-year scientific obsession that has culminated in this fascinating scientific adventure story–the first-ever intimate account of dolphin life in the wild.To Touch A Wild Dolphin is a seminal work that radically alters our fundamental understanding of these enigmatic creatures. Learning to identify scores of dolphins by their dorsal fin, Smolker and her team of scientists were able to conduct close and consistent studies that revealed the dolphin to be even more intelligent than we’d previously suspected. And while they were every bit as playful as we’ve known them to be, they also proved to have a dark and alarmingly violent side. But more than just a document on dolphins, this book is a touchingly personal look at the life of a scientist, at the rigors and sacrifices but also the wonders and joys of unending days in the field. Written with prose poetic and pristine, this book is nothing short of a landmark.

    Worms are the latest (as well as, of course, perhaps the oldest!) trend in earth-friendly gardening, and in this handy guide, the authors of DEAD SNAILS LEAVE NO TRAILS demystify the world of worm wrangling, with everything you need to know to build your own worm bin, make your garden worm-friendly, pamper your soil, and much much more.

    Beginning with the above questions, she began informally researching every affliction that she encountered in humans to learn whether it happened with animals, too. And usually, it did: dinosaurs suffered from brain cancer, koalas can catch chlamydia, reindeer seek narcotic escape in hallucinogenic mushrooms, stallions self-mutilate, and gorillas experience clinical depression. Natterson-Horowitz and science writer Kathryn Bowers have dubbed this pan-species approach to medicine zoobiquity. Here, they present a revelatory understanding of what animals can teach us about the human body and mind, exploring how animal and human commonality can be used to diagnose, treat, and heal patients of all species.

    In addition to his day job in the Oxfordshire countryside treating cows, dogs, pigs and cats, he's also worked with an astonishing range of species around the world, including crocodiles, rhinos and pandas.

    What better example exists of how adversity can produce something beautiful?We need look no farther than nature—from the habits of the porcupine to the sunflower to the wombat to the dragonfly—for small and simple things we can do to slow down, recharge, and living more thoughtfully, lovingly, and harmoniously.Wisdom From a Humble Jellyfish . . . is at once charming and scientific, packed with essential wisdom and practical tips worth borrowing from our plant and animal friends for life-changing self-care.

    They have brains that are huge for their body size and exhibit an avian kind of eloquence. They mate for life and associate with relatives and neighbors for years. And because they often live near people—in our gardens, parks, and cities—they are also keenly aware of our peculiarities, staying away from and even scolding anyone who threatens or harms them and quickly learning to recognize and approach those who care for and feed them, even giving them numerous, oddly touching gifts in return. With his extraordinary research on the intelligence and startling abilities of corvids—crows, ravens, and jays—scientist John Marzluff teams up with artist-naturalist Tony Angell to tell amazing stories of these brilliant birds in Gifts of the Crow. With narrative, diagrams, and gorgeous line drawings, they offer an in-depth look at these complex creatures and our shared behaviors. The ongoing connection between humans and crows—a cultural coevolution—has shaped both species for millions of years. And the characteristics of crows that allow this symbiotic relationship are language, delinquency, frolic, passion, wrath, risk-taking, and awareness—seven traits that humans find strangely familiar. Crows gather around their dead, warn of impending doom, recognize people, commit murder of other crows, lure fish and birds to their death, swill coffee, drink beer, turn on lights to stay warm, design and use tools, use cars as nutcrackers, windsurf and sled to play, and work in tandem to spray soft cheese out of a can. Their marvelous brains allow them to think, plan, and reconsider their actions. With its abundance of funny, awe-inspiring, and poignant stories, Gifts of the Crow portrays creatures who are nothing short of amazing. A testament to years of painstaking research and careful observation, this fully illustrated, riveting work is a thrilling look at one of nature’s most wondrous creatures.

    He has observed more than six thousand species during travels that have taken him to every continent. He founded the largest company in the world specializing in birding tours and one of the most respected ones in ecotourism. Emanuel has received some of birding’s highest honors, including the Roger Tory Peterson Award from the American Birding Association and the Arthur A. Allen Award from the Cornell Laboratory of Ornithology. He also started the first birding camps for young people, which he considers one of his greatest achievements.In One More Warbler, Emanuel recalls a lifetime of birding adventures—from his childhood sighting of a male Cardinal that ignited his passion for birds to a once-in-a-lifetime journey to Asia to observe all eight species of cranes of that continent. He tells fascinating stories of meeting his mentors who taught him about birds, nature, and conservation, and later, his close circle of friends—Ted Parker, Peter Matthiessen, George Plimpton, Roger Tory Peterson, and others—who he frequently birded and traveled with around the world. Emanuel writes about the sighting of an Eskimo Curlew, thought to be extinct, on Galveston Island; setting an all-time national record during the annual Audubon Christmas Bird Count; attempting to see the Imperial Woodpecker in northwestern Mexico; and birding on the far-flung island of Attu on the Aleutian chain. Over the years, Emanuel became a dedicated mentor himself, teaching hundreds of young people the joys and enrichment of birding. “Birds changed my life,” says Emanuel, and his stories make clear how a deep connection to the natural world can change everyone’s life.
