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.

    Will temperatures rise by 2�C or 8�C over the next hundred years? Will sea levels rise by 2 or 30 feet? The only way that we can accurately answer questions like these is by looking into the distant past, for a comparison with the world long before the rise of mankind.We may currently believe that atmospheric shifts, like global warming, result from our impact on the planet, but the earth's atmosphere has been dramatically shifting since its creation. This book reveals the crucial role that plants have played in determining atmospheric change - and hence the conditions on the planet we know today. Along the way a number of fascinating puzzles arise: Why did plants evolve leaves? When and how did forests once grow on Antarctica? How did prehistoric insects manage to grow so large? The answers show the extraordinary amount plants can tell us about the history of the planet -- something that has often been overlooked amongst the preoccuputations with dinosaur bones and animal fossils.David Beerling's surprising conclusions are teased out from various lines of scientific enquiry, with evidence being brought to bear from fossil plants and animals, computer models of the atmosphere, and experimental studies. Intimately bound up with the narrative describing the dynamic evolution of climate and life through Earth's history, we find Victorian fossil hunters, intrepid polar explorers and pioneering chemists, alongside wallowing hippos, belching volcanoes, and restless landmasses.

    Few people, however, know that research into tree rings has also made amazing contributions to our understanding of Earth's climate history and its influences on human civilization over the past 2,000 years. In her captivating new book, Tree Story, Valerie Trouet reveals how the seemingly simple and relatively familiar concept of counting tree rings has inspired far-reaching scientific breakthroughs that illuminate the complex interactions between nature and people.Trouet, a leading tree-ring scientist, takes us out into the field, from remote African villages to radioactive Russian forests, offering readers an insider's look at tree-ring research, a discipline formally known as dendrochronology. Tracing her own professional journey while exploring dendrochronology's history and applications, Trouet describes the basics of how tell-tale tree cores are collected and dated with ring-by-ring precision, explaining the unexpected and momentous insights we've gained from the resulting samples.Blending popular science, travelogue, and cultural history, Tree Story highlights exciting findings of tree-ring research, including the fate of lost pirate treasure, successful strategies for surviving California wildfire, the secret to Genghis Khan's victories, the connection between Egyptian pharaohs and volcanoes, and even the role of olives in the fall of Rome. These fascinating tales are deftly woven together to show us how dendrochronology sheds light on global climate dynamics and uncovers the clear links between humans and our leafy neighbors. Trouet delights us with her dedication to the tangible appeal of studying trees, a discipline that has taken her to austere and beautiful landscapes around the globe and has enabled scientists to solve long-pondered mysteries of Earth and its human inhabitants.

    

    Usually I decide to save the money so I do not have to earn more. En extremis, I repeat the old Yankee marching chant like a mantra: Make do! Wear it out! When it is gone, do without! Bum, Bum! Bum bi Dum! Bum bi di Dum, Bum bi Dum!

    Colin Elford spends his days alone - alone but for the deer, the squirrels, the rabbits, the birds, and the many other creatures inhabiting the woods. From the crisp cold of January, through the promise of spring and the heat of summer, and then into damp autumn and the chill winds of winter, we accompany the forest-ranger as he goes about his work - stalking in the early morning darkness, putting an injured fallow buck out of its misery, watching stoats kill a hare, observing owls, and simply being a part of the outdoors. Colin Elford immerses himself in the richly diverse and unique landscapes of Britain, existing in rhythm with natural environments. For fans of Robert Macfarlane's Landmarks, Helen Macdonald's H is for Hawk orJames Rebanks' A Shepherd's Life, Colin's rare and uplifiting journey will unveil the true nature and beauty of Britain's countryside.

    Little Brutus was destined to remain in captivity or, more likely, even euthanized due to overpopulation at the preserve. Anderson, already an expert in animal rescue and rehabilitation, just could not let that happen to Brutus, who looked like a "fuzzy Twinkie." From the beginning it was clear something special existed between the two. And so, Anderson built the Montana grizzly encounter in Bozeman, Montana, especially for Brutus, so that he, and others like him, could grow up "being a bear." And so the love story began.When together, Anderson and Brutus will wrestle, swim, play, and continue to act as advocates for grizzly protection and education, be it through documentaries like Expedition Grizzly, appearances on Oprah or Good Morning America, or in this inspiring book, which promises to be an intimate look into Anderson's relationship with Brutus and a call to action to protect these glorious animals and the natural world they live in.The Story of Brutus proves that love and friendship knows no bounds and that every care must be taken to protect one of nature's noblest creatures.

    Buchmann, one of the world's leading authorities on bees and pollination, and Gary Paul Nabhan, award-winning writer and renowned crop ecologist, explore the vital but little-appreciated relationship between plants and the animals they depend on for reproduction -- bees, beetles, butterflies, hummingbirds, moths, bats, and countless other animals, some widely recognized and other almost unknown.Scenes from around the globe -- examining island flora and fauna on the Galapagos, counting bees in the Panamanian rain forest, witnessing an ancient honey-hunting ritual in Malaysia -- bring to life the hidden relationships between plants and animals, and demonstrate the ways in which human society affects and is affected by those relationships. Buchmann and Nabhan combine vignettes from the field with expository discussions of ecology, botany, and crop science to present a lively and fascinating account of the ecological and cultural context of plant-pollinator relationships.More than any other natural process, plant-pollinator relationships offer vivid examples of the connections between endangered species and threatened habitats. The authors explain how human-induced changes in pollinator populations -- caused by overuse of chemical pesticides, unbridled development, and conversion of natural areas into monocultural cropland-can have a ripple effect on disparate species, ultimately leading to a "cascade of linked extinctions."

    

    As she investigates the names and meanings of trees, telling their legends and lore, she reminds us of just how innately bound we are to these protectors of our planet. Since the human race began, we have depended on them for food, shade, shelter and fuel, not to mention furniture, musical instruments, medicine utensils and more. Wells has a remarkable ability to dig up the curious and the captivating: At one time, a worm found in a hazelnut prognosticated ill fortune. Rowan trees were planted in churchyards to prevent the dead from rising from their graves. Greek arrows were soaked in deadly yew, and Shakespeare’s witches in Macbeth used “Gall of goat and slips of Yew” to make their lethal brew. One bristlecone pine, at about 4,700 years old, is thought to be the oldest living plant on earth. All this and more can be found in the beautifully illustrated pages (themselves born of birch bark!) of 100 Trees.
