Although Gerd Heinrich, a devoted naturalist, specialized in wasps, Bernd Heinrich tried to distance himself from his "old-fashioned" father, becoming a hybrid: a modern, experimental biologist with a naturalist's sensibilities.

In this extraordinary memoir, the award-winning author shares the ways in which his relationship with his father, combined with his unique childhood, molded him into the scientist, and man, he is today. From Gerd's days as a soldier in Europe and the family's daring escape from the Red Army in 1945 to the rustic Maine farm they came to call home, Heinrich relates it all in his trademark style, making science accessible and awe-inspiring.

A fascinating and important work of ornithology, which led E.O. Wilson to call it "one of the most interesting discoveries I've seen in animal sociobiology in years," "Ravens In Winter" is a scientist's impassioned study to understand the mysterious social habits of one of nature's most formidable birds, the raven.
Why do ravens, generally understood to be solitary creatures, share food between each other during winter? This was the question Bernd Heinrich asked himself as he was observing another one of his prime research subjects, the highly social bumblebee. And it was during these trips to Maine, the site of much of his research, where he first noticed this "unusual" behavior of ravens. From an evolutionary perspective, the raven's willingness to share food challenged conventional wisdom. There was no biological imperative, it seemed, to their communal spirit. The more Heinrich observed their habits, the more odd the bird's behavior became. What started as mere curiosity turned into an impassioned research project, and "Ravens In Winter," the first research of its kind, explores the fascinating biological puzzle of the raven's rather unconventional social habits.

Escapist fantasies usually involve the open road, but Bernd Heinrich's dream was to focus on the riches of one small place,a few green acres along Alder Brook just east of the Presidential Mountains. The year begins as he settles into a cabin with no running water and no electricity, built of hand-cut logs he dragged out of the woods with a team of oxen. There, alone except for his pet raven, Jack, he rediscovers the meaning of peace and quiet and harmony with nature,of days spent not filling out forms, but tracking deer, or listening to the sound of a moth's wings.Throughout this year when the subtle matters and the spectacular distracts," Heinrich brings us back to the drama in small things, when life is lived consciously. His story is that of a man rediscovering what it means to be alive.

Heinrich involves us in his quest to get inside the mind of the raven. But as animals can only be spied on by getting quite close, Heinrich adopts ravens, thereby becoming a "raven father," as well as observing them in their natural habitat. He studies their daily routines, and in the process, paints a vivid picture of the ravens' world. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation and analysis, we become their intimates too.

Heinrich's passion for ravens has led him around the world in his research. Mind of the Raven follows an exotic journey--from New England to Germany, and from Montana to Baffin Island in the high Arctic--offering dazzling accounts of how science works in the field, filtered through the eyes of a passionate observer of nature. Each new discovery and insight into raven behavior is thrilling to read, at once lyrical and scientific.

In Why We Run, biologist, award-winning nature writer, and ultramarathoner Bernd Heinrich explores a new perspective on human evolution by examining the phenomenon of ultraendurance and makes surprising discoveries about the physical, spiritual -- and primal -- drive to win. At once lyrical and scientific, Why We Run shows Heinrich's signature blend of biology, anthropology, psychology, and philosophy, infused with his passion to discover how and why we can achieve superhuman abilities.

All bodily activity is the result of the interplay of vastly complex physiological processes, and all of these processes depend on temperature. For insects, the struggle to keep body temperature within a suitable range for activity and competition is often a matter of life and death.

A few studies of temperature regulation in butterflies can be found dating back to the late 1800s, but only recently have scientists begun to study the phenomenon in other insects. In "The Thermal Warriors" Bernd Heinrich explains how, when, and in general what insects regulate their body temperature and what it means to them. As he shows us, the ingenuity of the survival strategies insects have evolved in the irreducible crucible of temperature is astonishing: from shivering and basking, the construction of turrets (certain tiger beetles), and cooling with liquid feces to stilting (some desert ants and beetles), "panting" in grasshoppers and "sweating cicada," and counter- and alternating-currents of blood flow for heat retention and heat loss.

In "The Thermal Warriors" Heinrich distills his great reference work, "The Hot-Blooded Insects," to its essence: the most significant and fascinating stories that illustrate general principles, all conveyed in the always engaging prose we have come to expect from this author.

Nature enthusiasts of all ages will learn to train their eyes and ears to be more alert to the lives and seasonal rhythms of the plants and animals in their own backyard. They will also learn the pleasures and benefits of keeping a nature observation journal with a specially designed format that accommodates a short observation every day for five years, making it easy and inviting to compare notes on the dates of annual events such as the appearance of the first buds on the trees, arrival of particular birds, rain and snow fall, and plant growth and harvests. With art from noted illustrator Bemd Heinrich throughout, The Naturalist's Notebook is a beautiful as well as practical, interactive tool for making nature observation and appreciation a regular routine for individuals and families.

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.

From flying squirrels to grizzly bears, and from torpid turtles to insects with antifreeze, the animal kingdom relies on some staggering evolutionary innovations to survive winter. Unlike their human counterparts, who must alter the environment to accommodate physical limitations, animals are adaptable to an amazing range of conditions.

Examining everything from food sources in the extremely barren winter land-scape to the chemical composition that allows certain creatures to survive, Heinrich's Winter World awakens the largely undiscovered mysteries by which nature sustains herself through winter's harsh, cruel exigencies.

Once in a great while, as the "New York Times" noted recently, a naturalist writes a book that changes the way people look at the living world. John James Audubon s "Birds of America, " published in 1838, was one. Roger Tory Peterson s 1934 "Field Guide to the Birds" was another. How does such insight into nature develop?

Pioneering a new niche in the study of plants and animals in their native habitat, " Field Notes on Science and Nature" allows readers to peer over the shoulders and into the notebooks of a dozen eminent field workers, to study firsthand their observational methods, materials, and fleeting impressions.

What did George Schaller note when studying the lions of the Serengeti? What lists did Kenn Kaufman keep during his 1973 big year ? How does Piotr Naskrecki use relational databases and electronic field notes? In what way is Bernd Heinrich s approach truly Thoreauvian, in E. O. Wilson s view? Recording observations in the field is an indispensable scientific skill, but researchers are not generally willing to share their personal records with others. Here, for the first time, are reproductions of actual pages from notebooks. And in essays abounding with fascinating anecdotes, the authors reflect on the contexts in which the notes were taken.

Covering disciplines as diverse as ornithology, entomology, ecology, paleontology, anthropology, botany, and animal behavior, "Field Notes "offers specific examples that professional naturalists can emulate to fine-tune their own field methods, along with practical advice that amateur naturalists and students can use to document their adventures.

"From one man's persistent and elegant probing of the temperature biology of bees, we have been led to a deeper understanding of the whole biology of many insect taxa, and of their interactions with ecological and environmental stresses: all who work at the interfaces of physiology, ecology and behaviour have cause to be grateful, and all should certainly read this book." (Trends in Ecology & Evolution) "An outstanding source of information, and can be read with profit and satisfaction by the professional biologist and interested amateur alike." (Nature)

The story and science of how animals find their way home. Home is the place we long for most, when we feel we have travelled too far, for too long. Since boyhood, acclaimed scientist and author Bernd Heinrich has returned every year to a beloved patch of woods in his native western Maine. But while it's the pull of nostalgia that informs our desire to go back, what is it that drives the homing instinct in animals? Heinrich explores the fascinating science behind the mysteries of animal migration: how geese imprint true visual landscape memory over impossible distances; how the subtlest of scent trails are used by many creatures, from fish to insects to amphibians, to pinpoint their home; and how the tiniest of songbirds are equipped for solar and magnetic orienteering over vast distances. Most movingly, Heinrich chronicles the spring return of a pair of sandhill cranes to their pond in the Alaska tundra. With his marvellously evocative prose, Heinrich portrays the psychological state of the newly arrived birds, articulating just what their yearly return truly means, to the birds and to those fortunate enough to witness this transcendently beautiful ritual. The Homing Instinct is an enchanting study of this phenomenon of the natural world, reminding us that to discount our own feelings toward home is to ignore biology itself.

How can cicadas survive--and thrive--at temperatures pushing 115F? Do hummingbirds know what they're up against before they migrate over the Gulf of Mexico? Why do some trees stop growing taller even when three months of warm weather remain? With awe and unmatched expertise, Bernd Heinrich's Summer World never stops exploring the beautifully complex interactions of animals and plants with nature, giving extraordinary depth to the relationships between habitat and the warming of the earth.

This engaging chronicle of how the author and the great horned owl "Bubo" came to know one another over three summers spent in the Maine woods--and of how Bubo eventually grew into an independent hunter--is now available in an edition that has been abridged and revised so as to be more accessible to the general reader.

Volume 4 offers a practical presentation of press law and broadcasting law. It also includes sports law and theater law along with legal questions related to child protection and protection of personal images.

The beauty of the robin s egg is not lost on the child who discovers the nest, nor on the collector of nature s marvels. Such instances of wonder find fitting expression in the photographs of Rosamond Purcell, whose work captures the intricacy of nests and the aesthetic perfection of bird eggs. Mining the ornithological treasures of the Western Foundation of Vertebrate Zoology, Purcell produces pictures as lovely and various as the artifacts she photographs. The dusky blue egg of an emu becomes a planet. A woodpecker s nest bears an uncanny resemblance to a wooden shoe. A resourceful rock dove weaves together scrap metal and spent fireworks. A dreamscape of dancing monkeys emerges from the calligraphic markings of a murre egg.

Alongside Purcell s photographs, Linnea Hall and Rene Corado offer an engaging history of egg collecting, the provenance of the specimens in the photographs, and the biology, conservation, and ecology of the birds that produced them. They highlight the scientific value that eggs and nest hold for understanding and conserving birds in the wild, as well as the aesthetic charge they carry for us.

How has evolution shaped the egg or directed the design of the nest? How do the photographs convey such infinitesimal and yet momentous happenstance? The objects in "Egg & Nest" are specimens of natural history, and in Purcell s renderings, they are also the most natural art.

How long should a leaf live? When should blueberries ripen? And what should a clever moose eat? Questions like these may seem simple or downright strange, yet they form the backbone of natural history, a discipline that fostered some of our most important scientific theories, from natural selection to glaciation. Through careful, patient observations of the organisms that live in an area, their distributions, and how they interact with other species, we gain a more complete picture of the world around us, and our place in it. In What Should a Clever Moose Eat?, John Pastor explores the natural history of the North Woods, an immense and complex forest that stretches from the western shore of Lake Superior to the far coast of Newfoundland. The North Woods is one of the most ecologically and geologically interesting places on the planet, with a host of natural history questions arising from each spruce or sugar maple. From the geological history of the region to the shapes of leaves and the relationship between aspens, caterpillars, and predators, Pastor delves into a captivating range of topics as diverse as the North Woods themselves. Through his meticulous observations of the natural world, scientists and non-scientists alike learn to ask natural history questions and form their own theories, gaining a greater understanding of and love for the North Woods, and other natural places precious to them. In the tradition of Charles Darwin and Henry David Thoreau, John Pastor is a joyful observer of nature who makes sharp connections and moves deftly from observation to theory. Take a walk in John Pastor's North Woods, you'll come away with a new appreciation for details, for the game trails, beaver ponds, and patterns of growth around you, and won't look at the natural world in the same way again.

As we follow the path of a giant water bug or peer over the wing of a gypsy moth, we glimpse our world anew, at once shrunk and magnified. Owing to their size alone, insects' experience of the world is radically different from ours. Air to them is as viscous as water to us. The predicament of size, along with the dizzying diversity of insects and their status as arguably the most successful organisms on earth, have inspired passion and eloquence in some of the world's most innovative scientists. A World of Insects showcases classic works on insect behavior, physiology, and ecology published over half a century by Harvard University Press. James Costa, Vincent Dethier, Thomas Eisner, Lee Goff, Bernd Heinrich, Bert Hoelldobler, Kenneth Roeder, Andrew Ross, Thomas Seeley, Karl von Frisch, Gilbert Waldbauer, E. O. Wilson, and Mark Winston-each writer, in his unique voice, paints a close-up portrait of the ways insects explore their environment, outmaneuver their enemies, mate, and care for kin. Selected by two world-class entomologists, these essays offer compelling descriptions of insect cooperation and warfare, the search for ancient insect DNA in amber, and the energy economics of hot-blooded insects. They also discuss the impact-for good and ill-of insects on our food supply, their role in crime scene investigation, and the popular fascination with pheromones, killer bees, and fire ants. Each entry begins with commentary on the authors, their topics, and the latest research in the field.

Media law as a means of organization in the real world and the virtual world continues to gain in economic and cultural importance. The global market and the networking of information and communication processes require an improved legal framework for media law in the 21st century. It is not merely production conditions that have been impacted by the digital revolution, but the manner of marketing media products and the use of such are increasingly being conducted in the Internet. In addition to the classical fields of media law, such as press, broadcasting and film, these five volumes also take into account issues pertaining to sports, theater and electronic media. The presentation includes media law-related aspects of the law of competition, telemedia law and copyright law as well as the laws regarding broadcasting, press, personality rights, telecommunications, data protection, samples/design, and domain rights; licensing contract law, the law of publication, media criminal law, photography law as well as media cartel law are also discussed. This complete presentation of media law particularly addresses the European legal framework. Attorneys, legal scholars and media experts comprehensively and systematically address the processes in society relevant to media law in their contributions to the five volumes of this handbook.

Why would a grown man chase hornets with a thermometer, paint whirligig beetles bright red, or track elephants through the night to fill trash bags with their prodigious droppings? Some might say-to advance science. Bernd Heinrich says-because it's fun. Heinrich, author of the much acclaimed Bumblebee Economics, has been playing in the wilds of one continent or another all his life. In the process, he has become one of the world's foremost physiological ecologists. With In a Patch of Fireweed, he will undoubtedly become one of our foremost writers of popular science. Part autobiography, part case study in the ways of field biology, In a Patch of Fireweed is an endlessly fascinating account of a scientist's life and work. For the author, it is an opportunity to report not just his results but the curiosity, humor, error, passion, and competitiveness that feed into the process of discovery. For the reader, it is simply a delight, a rare chance to share the perceptions of an unusual mind fully in tune with the inner workings of nature. Before his years of research in the woodlands and deserts of North America, the New Guinea highlands, and the plains of East Africa, Heinrich had a sense of the wild that few people in this century can know. He tells the whole story, from his refugee childhood hidden in a German forest, eating mice fried in boar fat, to his ongoing research in the woods surrounding his cabin in Maine.
