Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    In this revised edition, Merlin D. Tuttle, founder and science director of Bat Conservation International in Austin, Texas, offers bat aficionados the most up-to-date bat facts, including a wealth of new information on attracting bats and building bat houses and a totally revamped key to the identification of common North American species.

    Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The "Anthropocene," as the proposed new epoch has been named, is regularly in the news.Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised.This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: The nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

    Aspirin, the world's most widely used drug, is based on compounds originally extracted from the bark of a willow tree, and more than a quarter of medicines found on pharmacy shelves contain plant compounds. Now Western medicine, faced with health crises such as AIDS, Alzheimer's disease, and cancer, has begun to look to the healing plants used by indigenous peoples to develop powerful new medicines. Nowhere is the search more promising than in the Amazon, the world's largest tropical forest, home to a quarter of all botanical species on this planet—as well as hundreds of Indian tribes whose medicinal plants have never been studied by Western scientists. In Tales of a Shaman's Apprentice, ethnobotanist Mark J. Plotkin recounts his travels and studies with some of the most powerful Amazonian shamans, who taught him the plant lore their tribes have spent thousands of years gleaning from the rain forest.For more than a decade, Dr. Plotkin has raced against time to harvest and record new plants before the rain forests' fragile ecosystems succumb to overdevelopment—and before the Indians abandon their own culture and learning for the seductive appeal of Western material culture. Tales of a Shaman's Apprentice relates nine of the author's quests, taking the reader along on a wild odyssey as he participates in healing rituals; discovers the secret of curare, the lethal arrow poison that kills in minutes; tries the hallucinogenic snuff epena that enables the Indians to speak with their spirit world; and earns the respect and fellowship of the mysterious shamans as he proves that he shares both their endurance and their reverence for the rain forest. Mark Plotkin combines the Darwinian spirit of the great writer-explorers of the nineteenth century—curious, discursive, and rigorously scientific—with a very modern concern for the erosion of our environment and the vanishing culture of native peoples.
