    Why does music evoke such powerful moods? The answers are at last be- coming clear, thanks to revolutionary neuroscience and the emerging field of evolutionary psychology. Both a cutting-edge study and a tribute to the beauty of music itself, This Is Your Brain on Music unravels a host of mysteries that affect everything from pop culture to our understanding of human nature, including: • Are our musical preferences shaped in utero? • Is there a cutoff point for acquiring new tastes in music? • What do PET scans and MRIs reveal about the brain’s response to music? • Is musical pleasure different from other kinds of pleasure?This Is Your Brain on Music explores cultures in which singing is considered an essential human function, patients who have a rare disorder that prevents them from making sense of music, and scientists studying why two people may not have the same definition of pitch. At every turn, this provocative work unlocks deep secrets about how nature and nurture forge a uniquely human obsession.

    Now award-winning writer Carl Zimmer takes us on a fantastic voyage into the secret parasite universe we actually live in but haven't recognized. He reveals not only that parasites are the most successful life-forms on Earth, but that they triggered the development of sex, shape ecosystems, and have driven the engine of evolution. In mapping the parasite universe, Zimmer makes the astonishing observation that most species are parasites, and that almost every animal, including humans, will at one time or another become the home of a parasite. Zimmer shows how highly evolved parasites are and describes the frightening and amazing ingenuity these commando invaders use to devour their hosts from the inside and control their behavior. The sinister Sacculina carcini makes its home in an unlucky crab and proceeds to eat everything but what the crab needs to put food in its mouth, which Sacculina then consumes. When Sacculina finally reproduces, it places its young precisely where the crab would nurture its own progeny, and then has the crab nurture the foster family members. Single-celled Toxoplasma gondi has an even more insidious role, for it can invade the human brain. There it makes men distrustful and less willing to submit to social mores. Women become more outgoing and warm-hearted. Why would a parasite cause these particular personality changes? It seems Toxoplasma wants its host to be less afraid, to be more prone to danger and a violent end -- so that, in the carnage, it will be able to move on to another host. From the steamy jungles of Costa Rica to the fetid parasite heaven of rebel-held southern Sudan, Zimmer tracks the genius of parasitic life and its impact on humanity. We hosts have developed remarkable defenses against the indomitable parasite: our mighty immune system, our culturally enforced habit of keeping clean, and, perhaps most intriguingly, sex. But this is not merely a book about the evil power of parasitism and how we must defend against it. On the contrary, Zimmer concludes that humankind itself is a new kind of parasite, one that preys on the entire Earth. If we are to achieve the sophistication of the parasites on display here in vivid detail, if we are to promote the flourishing of life in all its diversity as they do, we must learn the ways nature lives with itself, the laws of Parasite Rex.

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

    He was a city boy, unsure of what lay ahead. When he entered the forest, which would go on to become one of the last strongholds of wild tigers, it had a profound effect on him, changing his life forever.For the next forty years, he studied nearly 200 Ranthambhore tigers, spending every waking moment in close proximity to these magnificent animals. Of the various tigers he observed a handful became extra special, and it is these which come to glorious life in this book. They include Padmini, the Queen Mother, the first tiger the author got to know well; Genghis, the master predator, who invented a way of killing prey in water, the first time this had been observed anywhere in the world; Noon, one of his all-time favourites, who received her name because she was most active in the middle of the day; Broken Tooth, an exceptionally gentle male; Laxmi, a devoted mother, whose methods of raising her cubs revolutionized tiger studies; Machli, the most famous tigress in Ranthambhore, and several more.

    In Wicked Plants, Stewart takes on over two hundred of Mother Nature’s most appalling creations. It’s an A to Z of plants that kill, maim, intoxicate, and otherwise offend. You’ll learn which plants to avoid (like exploding shrubs), which plants make themselves exceedingly unwelcome (like the vine that ate the South), and which ones have been killing for centuries (like the weed that killed Abraham Lincoln's mother). Menacing botanical illustrations and splendidly ghastly drawings create a fascinating portrait of the evildoers that may be lurking in your own backyard. Drawing on history, medicine, science, and legend, this compendium of bloodcurdling botany will entertain, alarm, and enlighten even the most intrepid gardeners and nature lovers.

     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.

    Yet, while common, oak woodlands are anything but ordinary. In a book rich in illustration and suffused with wonder, author Kate Marianchild combines extensive research and years of personal experience to explore some of the marvelous plants and animals that the oak woodlands nurture. Acorn woodpeckers unite in marriages of up to ten mates and raise their young cooperatively. Ground squirrels roll in rattlesnake skins to hide their scent from hungry snakes. Manzanita's rust-colored, paper-thin bark peels away in time for the summer solstice, exposing sinuous contours that are cool to the touch even on the hottest day. Conveying up-to-the-minute scientific findings with a storyteller's skill, Marianchild introduces us to a host of remarkable creatures in a world close by, a world that rustles, hums, and sings with the sounds of wild things.

    While these are essential, many young ecologists need to figure out how to actually do research themselves. How to Do Ecology provides nuts-and-bolts advice on how to develop a successful thesis and research program. This book presents different approaches to posing testable ecological questions. In particular, it covers the uses, strengths, and limitations of manipulative experiments in ecology. It will help young ecologists consider meaningful treatments, controls, replication, independence, and randomization in experiments, as well as where to do experiments and how to organize a season of work. This book also presents strategies for analyzing natural patterns, the value of alternative hypotheses, and what to do with negative results.Science is only part of being a successful ecologist. This engagingly written book offers students advice on working with other people and navigating their way through the land mines of research. Findings that don't get communicated are of little value. How to Do Ecology suggests effective ways to communicate information in the form of journal articles, oral presentations, and posters. Finally, it outlines strategies for developing successful grant and research proposals. Numerous checklists, figures, and boxes throughout the book summarize and reinforce the main points. In short, this book makes explicit many of the unspoken assumptions behind doing good research in ecology, and provides an invaluable resource for meaningful conversations among ecologists.

    Fuzzy brown molds mischievously turn forgotten peaches to slime in the kitchen fruit bowl. And in thousands of other ways, members of the kingdom Fungi do their part to make life on Earth the miracle that it is. In this lively book, George Hudler leads us on a tour of an often-overlooked group of organisms, which differ radically from both animals and plants. Along the way the author stops to ponder the marvels of nature and the impact of mere microbes on the evolution of civilization. Nature's ultimate recyclers not only save us from drowning in a sea of organic waste, but also provide us with food, drink, and a wide array of valuable medicines and industrial chemicals.Some fungi make deadly poisons and psychedelic drugs that have interesting histories in and of themselves, and Hudler weaves tales of those into his scientific account of the nature of the fungi. The role of fungi in the Irish potato famine, in the Salem Witch Trials, in the philosophical writings of Greek scholars, and in the creation of ginger snaps are just a few of the many great moments in history to grace these pages.Hudler moves so easily from discussing human history to exploring scientific knowledge, all with a sense of humor and enthusiasm, that one can well understand why he is an award-winning teacher both at Cornell University as well as nationally. Few, for instance, who read his invitation to get out of your chair and take a short walk will ever again look without curiosity and admiration at the rotten part of the world around them. Magical Mushrooms, Mischievous Molds is full of information that will satisfy history buffs, science enthusiasts, and anyone interested in nature's miracles. Everyone in Hudler's audience will develop a new appreciation of the debt they owe to the molds for such common products as penicillin, wine, and bread.
