Colorful, mysterious, and often fantastically shaped, fungi have been a source of wonder and fascination since the earliest hunter-gatherers first foraged for them. Today there are few, if any, places on Earth where fungi have not found themselves a home. And these highly specialized organisms are an indispensable part of the great chain of life. They not only partner in symbiotic relationships with over ninety percent of the world’s trees and flowering plant species, they also recycle and create humus, the fertile soil from which such flora receive their nutrition. Some fungi are parasites or saprotrophs; many are poisonous and, yes, hallucinogenic; others possess life-enhancing properties that can be tapped for pharmaceutical products; while a delicious few are prized by epicureans and gourmands worldwide.

In this lavishly illustrated volume, six hundred fungi from around the globe get their full due. Each species here is reproduced at its actual size, in full color, and is accompanied by a scientific explanation of its distribution, habitat, association, abundance, growth form, spore color, and edibility. Location maps give at-a-glance indications of each species’ known global distribution, and specially commissioned engravings show different fruitbody forms and provide the vital statistics of height and diameter. With information on the characteristics, distinguishing features, and occasionally bizarre habits of these fungi, readers will find in this book the common and the conspicuous, the unfamiliar and the odd. There is a fungal predator, for instance, that hunts its prey with lassos, and several that set traps, including one that entices sows by releasing the pheromones of a wild boar.

Mushrooms, morels, puffballs, toadstools, truffles, chanterelles—fungi from habitats spanning the poles and the tropics, from the highest mountains to our own backyards—are all on display in this definitive work.

Of all our childhood memories, few are quite as thrilling, or as tactile, as those of climbing trees. Scampering up the rough trunk, spying on the world from the cool green shelter of the canopy, lying on a limb and looking up through the leaves at the summer sun almost made it seem as if we were made for trees, and trees for us.Even in adulthood, trees retain their power, from the refreshing way their waves of green break the monotony of a cityscape to the way their autumn transformations take our breath away. 

In this lavishly illustrated volume, the trees that have enriched our lives finally get their full due, through a focus on the humble leaves that serve, in a sense, as their public face. The Book of Leaves offers a visually stunning and scientifically engaging guide to six hundred of the most impressive and beautiful leaves from around the world. Each leaf is reproduced here at its actual size, in full color, and is accompanied by an explanation of the range, distribution, abundance, and habitat of the tree on which it’s found. Brief scientific and historical accounts of each tree and related species include fun-filled facts and anecdotes that broaden its portrait. 

The Henry’s Maple, for instance, found in China and named for an Irish doctor who collected leaves there, bears little initial resemblance to the statuesque maples of North America, from its diminutive stature to its unusual trifoliolate leaves. Or the Mediterranean Olive, which has been known to live for more than 1,500 years and whose short, narrow leaves only fall after two or three years, pushed out in stages by the emergence of younger leaves.

From the familiar friends of our backyards to the giants of deep woods, The Book of Leaves brings the forest to life—and to our living rooms—as never before.

From Roman times to the present, knowledge of plants and their cultivation have exerted a deep impact on cultural changes. This book highlights the religious, artistic, political, and economic consequences of horticultural pursuits.

Far from a mere trade, horticulture profoundly affected Jewish and Persian mystical poetry and caused deep changes in Ottoman arts. It contributed to economic and political changes in Judea, Al Andalus, Japan, Yuan China, early modern Mexico, Europe, and the United States. This book explores the roles of peasants, botanists, horticulturists, nurserymen and gentlemen collectors in these developments, and concludes with a reflection on the future of horticulture in the present context of widespread environmental devastation and ecological uncertainty.

This book brings together an international body of scholars working on eighteenth-century botany within the context of imperial expansion. The eighteenth century saw widespread exploration, a tremendous increase in the traffic in botanical specimens, taxonomic breakthroughs, and horticultural experimentation. The contributors to this volume compare the impact of new developments and discoveries across several regions, broadening the geographical scope of their inquiries to encompass imperial powers that did not have overseas colonial possessions—such as the Russian, Ottoman, and Qing empires and the Tokugawa shogunate—as well as politically borderline regions such as South Africa, Yemen, and New Zealand.

The essays in this volume examine the botanical ambitions of eighteenth-century empires; the figure of the botanical explorer; the links between imperial ambition and the impulse to survey, map, and collect botanical specimens in “new” territories; and the relationships among botanical knowledge, self-representation, and material culture.

Arousal is fundamental to all cognition. It is intuitively obvious, absolutely necessary, but what exactly is it? In Brain Arousal and Information Theory, Donald Pfaff presents a daring perspective on this long-standing puzzle. Pfaff argues that, beneath our mental functions and emotional dispositions, a primitive neuronal system governs arousal. Employing the simple but powerful framework of information theory, Pfaff revolutionizes our understanding of arousal systems in the brain.

Starting with a review of the neuroanatomical, neurophysiological, and neurochemical components of arousal, Pfaff asks us to look at the gene networks and neural pathways underlying the brain’s arousal systems much as a design engineer would contemplate information systems. This allows Pfaff to postulate that there is a bilaterally symmetric, bipolar system universal among mammals that readies the animal or the human being to respond to stimuli, initiate voluntary locomotion, and react to emotional challenges. Applying his hypothesis to heightened states of arousal—sex and fear—Pfaff shows us how his theory opens new scientific approaches to understanding the structure of brain arousal.

A major synthesis of disparate data by a preeminent neuroscientist, Brain Arousal and Information Theory challenges current thinking about cognition and behavior. Whether you subscribe to Pfaff’s theory or not, this book will stimulate debate about the nature of arousal itself.

Female and male brains are different, thanks to hormones coursing through the brain before birth. That’s taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren’t more women physicists or more stay-at-home dads.

In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of “human brain organization theory,” Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out the limits of their own studies, other researchers and journalists can easily ignore them because brain organization theory just sounds so right. But if a series of methodological weaknesses, questionable assumptions, inconsistent definitions, and enormous gaps between ambiguous findings and grand conclusions have accumulated through the years, then science isn’t scientific at all.

Elegantly written, this book argues passionately that the analysis of gender differences deserves far more rigorous, biologically sophisticated science. “The evidence for hormonal sex differentiation of the human brain better resembles a hodge-podge pile than a solid structure…Once we have cleared the rubble, we can begin to build newer, more scientific stories about human development.”

North America’s fastest mammal, the pronghorn can accelerate explosively from a standing start to a top speed of 60 miles per hour—but it can also cruise at 45 miles per hour for many miles. What accounts for the speed of this extraordinary animal, a denizen of the American outback, and what can be observed of this creature’s way of life? And what is it like to be a field biologist dedicating twenty years to studying this species? In Built for Speed, John A. Byers answers these questions as he draws an intimate portrait of the most charismatic resident of the American Great Plains.

The National Bison Range in western Montana, established in 1908 to snatch bison from the brink of extinction, also inadvertently rescued the largest known remnant of Palouse Prairie. It is within this grassland habitat—home to meadowlarks, rattlesnakes, bighorn sheep, coyotes, elk, snipe, and a panoply of wildflowers—that Byers observes the pronghorn’s life from birth to death (a life often as brief as four days, sometimes as long as fifteen years) and from season to season. Readers will also experience the vicarious pleasures of a biologist who is eager to race a pronghorn in his truck, scrutinize bison dung through binoculars, and peer through the gathering dusk of a rainy evening to count the display dives of snipe.

A vivid and memorable tale of a first-rate scientist’s twenty-year encounter with a magnificent animal, the story of the pronghorn is also a reminder of the crucial role we can play in preserving the fleeting life of the native American grassland.

Here is a brilliant introduction to insect and plant ecology focusing on one of nature’s most adaptive creatures, the bumblebee. Survival for the bumblebee depends on its ability to regulate body temperature through a complex energy exchange, and it is this management of energy resources around which Bernd Heinrich enters his discussion of physiology, behavior, and ecological interaction. Along the way, he makes some amusing parallels with the theories of Adam Smith—which, Heinrich observes, work rather well for the bees, however inadequate they may be for human needs.

Bumblebee Economics uniquely offers both the professional and amateur scientist a coherent biological model that goes beyond any particular species or level of biological organization. Rich in specific detail and including an extensive appendix on the rearing of bumblebees, as well as a full-color guide to field identification, this book organizes practical knowledge according to a new criterion.

In a new preface, Heinrich ranges from Maine to Alaska and north to the Arctic as he summarizes findings from continuing investigations over the past twenty-five years—by himself and others—into the wondrous “energy economy” of bumblebees.
