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.

    But the environmental emergency is also a crisis for our philosophical habits of thought, confronting us with a problem that seems to defy not only our control but also our understanding. Global warming is perhaps the most dramatic example of what Timothy Morton calls “hyperobjects”—entities of such vast temporal and spatial dimensions that they defeat traditional ideas about what a thing is in the first place. In this book, Morton explains what hyperobjects are and their impact on how we think, how we coexist with one another and with nonhumans, and how we experience our politics, ethics, and art.Moving fluidly between philosophy, science, literature, visual and conceptual art, and popular culture, the book argues that hyperobjects show that the end of the world has already occurred in the sense that concepts such as world, nature, and even environment are no longer a meaningful horizon against which human events take place. Instead of inhabiting a world, we find ourselves inside a number of hyperobjects, such as climate, nuclear weapons, evolution, or relativity. Such objects put unbearable strains on our normal ways of reasoning.Insisting that we have to reinvent how we think to even begin to comprehend the world we now live in, Hyperobjects takes the first steps, outlining a genuinely postmodern ecological approach to thought and action.

    It really is our final warning. Mark Lynas delivers a vital account of the future of our earth, and our civilisation, if current rates of global warming persist. And it’s only looking worse.We are living in a climate emergency. But how much worse could it get? Will civilisation collapse? Are we already past the point of no return? What kind of future can our children expect? Rigorously cataloguing the very latest climate science, Mark Lynas explores the course we have set for Earth over the next century and beyond. Degree by terrifying degree, he charts the likely consequences of global heating and the ensuing climate catastrophe.  At one degree – the world we are already living in – vast wildfires scorch California and Australia, while monster hurricanes devastate coastal cities. At two degrees the Arctic ice cap melts away, and coral reefs disappear from the tropics. At three, the world begins to run out of food, threatening millions with starvation. At four, large areas of the globe are too hot for human habitation, erasing entire nations and turning billions into climate refugees. At five, the planet is warmer than for 55 million years, while at six degrees a mass extinction of unparalleled proportions sweeps the planet, even raising the threat of the end of all life on Earth. These escalating consequences can still be avoided, but time is running out. We must largely stop burning fossil fuels within a decade if we are to save the coral reefs and the Arctic. If we fail, then we risk crossing tipping points that could push global climate chaos out of humanity’s control. This book must not be ignored. It really is our final warning.

    She delivers a rapturous celebration of other species that is also a warning to our own. Traveling from the Amazon rain forest to a forbidding island off the coast of Japan, enduring everything from broken ribs to a beating by an irate seal, Ackerman reveals her subjects in all their splendid particularity. She shows us how they feed, mate, and migrate. She eavesdrops on their class and courtship dances. She pays tribute to the men and women hwo have deoted their lives to saving them.

    The trilobites, which dominated the ocean floors for 300 million years, are gone. The last of the dinosaurs was wiped out by a Mount Everest-sized meteorite that slammed into the earth 65 million years ago. The great flying reptiles are gone, and so are the marine reptiles, some of them larger than a humpback whale. Before humans crossed the Bering land bridge some 15,000 years ago, North America was populated by mastodons, mammoths, saber-toothed tigers, and cave bears. They too are MIA. Passenger pigeons once flew over North America in flocks that numbered in the billions; the last one died in 1914.In this book you will meet creatures that were driven to extinction even more recently, as well as some that were brought back from the brink. You will even encounter animals not known to exist until recently -- an antidote to extinction.

    But in the early twentieth century, an exotic plague swept through the chestnut forests with the force of a wildfire. Within forty years, the blight had killed close to four billion trees and left the species teetering on the brink of extinction. It was one of the worst ecological blows to North America since the Ice Age—and one most experts considered beyond repair. In American Chestnut, Susan Freinkel tells the dramatic story of the stubborn optimists who refused to let this cultural icon go. In a compelling weave of history, science, and personal observation, she relates their quest to save the tree through methods that ranged from classical plant breeding to cutting-edge gene technology. But the heart of her story is the cast of unconventional characters who have fought for the tree for a century, undeterred by setbacks or skeptics, and fueled by their dreams of restored forests and their powerful affinity for a fellow species.

    In this extraordinary feat of nature writing, we meet ants who harvest crops, raise insects as livestock, build roadways and bridges, embark on nuptial flights, and make war.

    Not so anymore. All but exterminated, these predators of the not-too-distant past have been reduced to minor players of the modern era. And what of it? Wildlife journalist William Stolzenburg follows in the wake of nature's topmost carnivores, and finds chaos in their absence.From the brazen mobs of deer and marauding raccoons of backyard America to streamsides of Yellowstone National Park crushed by massive herds of elk; from urchin-scoured reefs in the North Pacific to ant-devoured islands in Venezuela, Stolzenburg leads a startling tour through bizarre, impoverished landscapes of pest and plague. For anyone who has seldom given thought to the meat-eating beasts so recently missing from the web of life, here is a world of reason to think again.

    Throughout his celebrated career, Schaller has spent more time in Tibet than in any other part of the world, devoting more than thirty years to the wildlife, culture, and landscapes that captured his heart and continue to compel him to protect them.  Tibet Wild is Schaller’s account of three decades of exploration in the most remote stretches of Tibet: the wide, sweeping rangelands of the Chang Tang and the hidden canyons and plunging ravines of the southeastern forests. As engaging as he is enlightening, Schaller illustrates the daily struggles of a field biologist trying to traverse the impenetrable Chang Tang, discover the calving grounds of the chiru or Tibetan antelope, and understand the movements of the enigmatic snow leopard.    As changes in the region accelerated over the years, with more roads, homes, and grazing livestock, Schaller watched the clash between wildlife and people become more common—and more destructive. Thus what began as a purely scientific endeavor became a mission: to work with local communities, regional leaders, and national governments to protect the unique ecological richness and culture of the Tibetan Plateau.    Whether tracking brown bears, penning fables about the tiny pika, or promoting a conservation preserve that spans the borders of four nations, Schaller has pursued his goal with a persistence and good humor that will inform and charm readers.  Tibet Wild is an intimate journey through the changing wilderness of Tibet, guided by the careful gaze and unwavering passion of a life-long naturalist.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    In this disturbing new book, Lovelock guides us toward a hard reality: soon, we may not be able to alter the oncoming climate crisis. Lovelock’s influential Gaia theory, one of the building blocks of modern climate science, conceives of the Earth, including the atmosphere, oceans, biosphere and upper layers of rock, as a single living super-organism, regulating its internal environment much as an animal regulates its body temperature and chemical balance. But now, says Lovelock, that organism is sick. It is running a fever born of the combination of a sun whose intensity is slowly growing over millions of years, and an atmosphere whose greenhouse gases have recently spiked due to human activity. Earth will adjust to these stresses, but on time scales measured in the hundreds of millennia. It is already too late, Lovelock says, to prevent the global climate from “flipping” into an entirely new equilibrium state that will leave the tropics uninhabitable, and force migration to the poles. The Revenge of Gaia explains the stress the planetary system is under and how humans are contributing to it, what the consequences will be, and what humanity must do to rescue itself.

    It traces the origins of the concept, discusses the thinkers who have shaped it, and shows how it in turn has shaped the modern perception of our place in nature. The book includes portraits of Linnaeus, Gilbert White, Darwin, Thoreau, and such key twentieth-century ecologists as Rachel Carson, Frederic Clements, Aldo Leopold, James Lovelock, and Eugene Odum. It concludes with a new Part VI, which looks at the directions ecology has taken most recently.

    As a young ornithology instructor at the Hog Island Audubon Camp, Dr. Stephen W. Kress learned that puffins had nested on nearby islands until extirpated by hunters in the late 1800s. To right this environmental wrong, he resolved to bring puffins back to one such island—Eastern Egg Rock. Yet bringing the plan to reality meant convincing skeptics, finding resources, and inventing restoration methods at a time when many believed in “letting nature take its course.” Today, Project Puffin has restored more than 1,000 puffin pairs to three Maine islands. But even more exciting, techniques developed during the project have helped to restore rare and endangered seabirds worldwide. Further, reestablished puffins now serve as a window into the effects of global warming. The success of Dr. Kress’s project offers hope that people can restore lost wildlife populations and the habitats that support them. The need for such inspiration has never been greater.

    It has an ecological approach that explains the fundamentals of soil science effectively. Chapter topics include Soil Erosion and Its Control, Soil Acidity, Soils and Chemical Pollution, and Organisms and the Ecology of the Soil. For individuals interested in soil and the environment."

    The Eighth Edition has been thoroughly revised and updated and is available in both print and e-book formats.Janeway s Immunobiology continues to set the standard for currency and authority with its clear writing style and organization, uniform art program, and scientific accuracy. It presents a consistent point of view throughout that of the host s interaction with an environment containing many species of potentially harmful microorganisms. The full-color art program is conceptually coherent and illustrates the processes and mechanisms underlying the concepts in the text. The 16 chapters in this readable, accessible textbook are organized and presented in such a way as to help deliver a complete one-semester immunology course, beginning with innate immunity, then moving to adaptive immunity, and ending with applied clinical immunology.Discussion questions are provided at the end of Chapters 2 to 16. These questions can be used for review, or as the basis for discussion in class or in informal study groups. Summaries conclude each section and each chapter. As in previous editions, a caduceus icon in the margins indicates topics which are correlated to Case Studies in Immunology, Sixth Edition by Geha and Notarangelo.New in the Eighth EditionInnate immunity has been updated and expanded and is now presented in two separate chapters (Chapters 2 and 3), as well as being further emphasized in the rest of the textbook. Chapter 2 covers antimicrobial peptides and the complement system, and Chapter 3 deals with cellular innate receptors and cell-mediated innate immunity (e.g. TLRs, phagocytosis, NK cells, interferon production, innate-like lymphocytes). The section on complement has been reworked and reconceived explaining the lectin pathway first making it easier to teach by placing it into the context of innate recognition. Evolution is now incorporated throughout the text, helping students see similar strategies used by different organisms. The text and figures of Chapter 7 Signaling Through Immune System Receptors have been revised to present a cohesive synthesis of signaling for immunology, focusing on improved illustration of antigen recognition signaling and lymphocyte activation. Signaling through other receptors is dealt with wherever appropriate throughout the book. Updated chapter on B-cell immune responses (Chapter 10), especially on trafficking of B cells in peripheral lymphoid organs (e.g. lymph nodes) and the locations at which they encounter antigen. Coverage of mucosal immunity (Chapter 12) has been brought up to date, including responses to the commensal microbiota and the role of specialized dendritic cells and the regulatory T cells in maintaining tolerance to food antigens and commensal bacteria. Chapter 13, Failures of Host Defense Mechanisms, has been reorganized and revised to structure an understanding of primary immunodeficiencies in the context of developmental pathways. Chapter 16, Manipulation of the Immune Response, has been heavily revised to include a greater emphasis on clinical issues and a complete update of immunotherapeutics and vaccines. Many new and revised figures illustrate the processes and mechanisms underlying the concepts presented in the text. The icons used have been updated and expanded to incorporate a new emphasis on signaling pathways. New references have been added throughout the text.
