Memory is not their guide — no one butterfly makes the round trip — but each year somehow find their way to the same fifty acres of forest on the high slopes of Mexico’s Neovolcanic Mountains, and then make the return trip in the spring.In Four Wings and a Prayer, Sue Halpern sets off on an adventure to delve into the secrets behind this extraordinary phenomenon. She visits scientists and butterfly lovers across the country, offering a keenly observed portrait of the monarchs’ migration and of the people for whom they have become a glorious obsession. Combining science, memoir, and travel writing, Four Wings and a Prayer is an absorbing travelogue and a fascinating meditation on a profound mystery of the natural world.

    Half-poet and half-geologist, he recorded his experiences and reflections in Travels in Alaska, a work he was in the process of completing at the time of his death in 1914. As Edward Hoagland writes in his Introduction, “A century and a quarter later, we are reading [Muir’s] account because there in the glorious fiords . . . he is at our elbow, nudging us along, prompting us to understand that heaven is on earth—is the Earth—and rapture is the sensible response wherever a clear line of sight remains.”This Modern Library Paperback Classic includes photographs from the original 1915 edition.

     What drives a man to travel to sixty countries and spend a fortune to count birds? And what if that man is your father? Richard Koeppel's obsession began at the age of eleven, in Queens, New York, when he first spotted a Brown Thrasher and promptly jotted the sighting in a notebook. Several decades, one failed marriage, and two sons later, he added an astonishing 517 birds to that list on a single trip to Kenya. Soon after, he ended the last romantic relationship he would ever have, scaled down his medical practice, and decided to see every bird on earth, becoming a "Big Lister," a member of a subculture of competitive bird-watchers worldwide, all pursuing the same goal. Over twenty-five years, he collected more than 7,000 species (of a known 9,600), becoming one of about ten people ever to do so. "To See Every Bird on Earth" explores the thrill of this chase, the all-absorbing crusade at the expense of all else, and travel, to places both dangerous and dull, for the sake of making a check mark in a notebook. It's also the story of obsession-answering the questions why list? and why birds?-and how it defines us. A riveting glimpse into a fascinating subculture, To See Every Bird on Earth traces the love, loss, and reconnection between a father and a son, and explains why birds are so critical to the human search for our place in the world.

    When the Branch Davidian compound in Waco caught fire, when a terrorist-flown plane crashed into the Pentagon, and when mass graves were uncovered in Croatia, the authorities called Owsley. Through cutting-edge science, instinctive artistry, and dogged tenacity, Owsley painstakingly rebuilds the skeleton, and helps identify it and determine the cause of death.A curator for the Smithsonian's Museum of Natural History, Doug Owsley has handled over ten thousand human skeletons, more than anyone else in America. He has worked with America's historic skeletons, from, colonial Jamestown burials to Plains Indians to Civil War soldiers to skeletons tens of thousands of years old.That includes the Kennewick Man, a 9,600-year-old human skeleton found in shallow water along the banks of Washington State's Columbia River. It was a skeleton that would turn Owsley's life upside down.Days before Owsley was scheduled to begin studying the skeleton, the U.S. Army Corps of Engineers seized it and announced they would repatriate Kennewick Man, burying his bones on the land of the Native American tribes who claimed him. Along with seven of America's leading scientists, Owsley sued the U.S. government over custody. At stake was a wide body of knowledge about our past and our history that would be lost forever if the bones were reburied. For six years, Owsley fought a legal and political battle that put everything at risk, jeopardizing his career and his reputation.

    Through dramatic graphics and age-appropriate text, this authoritative volume charts the discovery of all the main types of dinosaurs and reveals the latest details on how these creatures most likely looked, behaved, defended themselves, found food, cared for their young, and interacted. Stunning murals, based on scientific evidence, depict various dinosaurs in their habitats--beautifully complementing the color photographs, paintings, charts, and maps. Some 53 major types of dinosaurs are described, representing a wide range of physical structures, sizes, and lifestyles.The book presents recent discoveries and current scientific thought--including the dinosaur-bird connection, profiles of feathered dinosaurs, and theories on dinosaur extinction. Readers also see how today' s paleontologists obtain evidence, piece together clues, and continue to reconstruct life in prehistoric times.

    Congress declared the locust “the single greatest impediment to the settlement of the country between Mississippi and the Rocky Mountains.” Throughout the nineteenth century, swarms of locusts regularly swept across the American continent, turning noon into dusk, devastating farm communities, and bringing trains to a halt. The outbreaks subsided in the 1890s, and then, suddenly—and mysteriously—the Rocky Mountain locust vanished. A century later, entomologist Jeffrey Lockwood vowed to discover why.Locust is the story of how one insect shaped the history of the western United States. A compelling personal narrative drawing on historical accounts and modern science, this beautifully written book brings to life the cultural, economic, and political forces at work in America in the late nineteenth century, even as it solves one of the greatest extinction mysteries of our time.

    An ancient curse. A stunning medical mystery. And a pioneering journey into the unknown heart of the world's densest jungle.Since the days of conquistador Hernán Cortés, rumors have circulated about a lost city of immense wealth hidden somewhere in the Honduran interior, called the White City or the Lost City of the Monkey God. Indigenous tribes speak of ancestors who fled there to escape the Spanish invaders, and they warn that anyone who enters this sacred city will fall ill and die. In 1940, swashbuckling journalist Theodore Morde returned from the rainforest with hundreds of artifacts and an electrifying story of having found the Lost City of the Monkey God-but then committed suicide without revealing its location.Three quarters of a century later, author Doug Preston joined a team of scientists on a groundbreaking new quest. In 2012 he climbed aboard a rickety, single-engine plane carrying the machine that would change everything: lidar, a highly advanced, classified technology that could map the terrain under the densest rainforest canopy. In an unexplored valley ringed by steep mountains, that flight revealed the unmistakable image of a sprawling metropolis, tantalizing evidence of not just an undiscovered city but an enigmatic, lost civilization.Venturing into this raw, treacherous, but breathtakingly beautiful wilderness to confirm the discovery, Preston and the team battled torrential rains, quickmud, disease-carrying insects, jaguars, and deadly snakes. But it wasn't until they returned that tragedy struck: Preston and others found they had contracted in the ruins a horrifying, sometimes lethal-and incurable-disease.

    Construction comes to a violent halt when two maneless lions devour 140 workers in an extended feeding frenzy that would make headlines and history all over the world. Caputo's Ghosts of Tsavo is a new quest for truth about the origins of these near-mythical animals and how they became predators of human flesh.

    Its effects on our view of life have been wide and deep. One of the most world-shaking books ever published, Charles Darwin's On the Origin of Species, first appeared in print over 130 years ago, and it touched off a debate that rages to this day.Every modern evolutionist turns to Darwin's work again and again. Current controversies in the life sciences very often have as their starting point some vagueness in Darwin's writings or some question Darwin was unable to answer owing to the insufficient biological knowledge available during his time. Despite the intense study of Darwin's life and work, however, many of us cannot explain his theories (he had several separate ones) and the evidence and reasoning behind them, nor do we appreciate the modifications of the Darwinian paradigm that have kept it viable throughout the twentieth century.Who could elucidate the subtleties of Darwin's thought and that of his contemporaries and intellectual heirs--A. R. Wallace, T. H. Huxley, August Weismann, Asa Gray--better than Ernst Mayr, a man considered by many to be the greatest evolutionist of the century? In this gem of historical scholarship, Mayr has achieved a remarkable distillation of Charles Darwin's scientific thought and his enormous legacy to twentieth-century biology. Here we have an accessible account of the revolutionary ideas that Darwin thrust upon the world. Describing his treatise as "one long argument," Darwin definitively refuted the belief in the divine creation of each individual species, establishing in its place the concept that all of life descended from a common ancestor. He proposed the idea that humans were not the special products of creation but evolved according to principles that operate everywhere else in the living world; he upset current notions of a perfectly designed, benign natural world and substituted in their place the concept of a struggle for survival; and he introduced probability, chance, and uniqueness into scientific discourse.This is an important book for students, biologists, and general readers interested in the history of ideas--especially ideas that have radically altered our worldview. Here is a book by a grand master that spells out in simple terms the historical issues and presents the controversies in a manner that makes them understandable from a modern perspective.

    Yet only in very recent years have scientists begun to turn the tools of modem science on this remarkable animal that has been so wrapped up in human dreams and legends. Now modern scientific research is beginning to explain long-standing mysteries about the true nature of the horse. How well can horses really see? What causes breakdowns in racehorses? How intelligent are they compared to other animals, and are some breeds smarter than others? Does nature or nurture matter more in creating a great sport horse? What causes cribbing and other vices? In this beautifully illustrated, compelling narrative, Budiansky tells the story of the origins, behavior, intelligence and language of the horse. For the first time, horse lovers will have access to cutting-edge research on topics of interest including new information on horse vision, horse biology and movement. Introducing the latest archeological findings, Budiansky presents a fascinating discussion of how the horse evolved as well as a dramatic and provocative history of man's use and abuse of the horse from prehistoric times to today. In a revealing chapter on horse intelligence, he debunks the commonly held belief that horses are stupid and also presents compelling new scientific information on horse language which will greatly benefit the horse rider and trainer. Finally, drawing together the latest research on horse physiology, genetics and biomechanics, Budiansky asks the million dollar question -- what makes for a winning racehorse? Anyone who loves horses will find this an invaluable resource as well as a fascinating read.

    And despite centuries of study there is always more to know. In 2008, paleontologist John A. Long and a team of researchers revealed their discovery of a placoderm fish fossil, known as “the mother fish,” which at 380 million years old revealed the oldest vertebrate embryo—the earliest known example of internal fertilization. As Long explains, this find led to the reexamination of countless fish fossils and the discovery of previously undetected embryos. As a result, placoderms are now considered to be the first species to have had intimate sexual reproduction or sex as we know it—sort of. Inspired by this incredible find, Long began a quest to uncover the paleontological and evolutionary history of copulation and insemination. In The Dawn of the Deed, he takes readers on an entertaining and lively tour through the sex lives of ancient fish and exposes the unusual mating habits of arthropods, tortoises, and even a well-endowed (16.5 inches!) Argentine Duck. Long discusses these significant discoveries alongside what we know about reproductive biology and evolutionary theory, using the fossil record to provide a provocative account of prehistoric sex. The Dawn of the Deed also explores fascinating revelations about animal reproduction, from homosexual penguins to monogamous seahorses to the difficulties of dinosaur romance and how sexual organs in ancient shark-like fishes actually relate to our own sexual anatomy. The Dawn of the Deed is Long’s own story of what it’s like to be a part of a discovery that rewrites evolutionary history as well as an absolutely rollicking guide to sex throughout the ages in the animal kingdom. It’s natural history with a naughty wink.

    Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe--descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their evolutionary cousins went extinct?The Invaders musters compelling evidence to show that the major factor in the Neanderthals' demise was direct competition with newly arriving humans. Drawing on insights from the field of invasion biology, which predicts that the species ecologically closest to the invasive predator will face the greatest competition, Pat Shipman traces the devastating impact of a growing human population: reduction of Neanderthals' geographic range, isolation into small groups, and loss of genetic diversity.But modern humans were not the only invaders who competed with Neanderthals for big game. Shipman reveals fascinating confirmation of humans' partnership with the first domesticated wolf-dogs soon after Neanderthals first began to disappear. This alliance between two predator species, she hypothesizes, made possible an unprecedented degree of success in hunting large Ice Age mammals--a distinct and ultimately decisive advantage for humans over Neanderthals at a time when climate change made both groups vulnerable.

    She eats road kill, wrestles alligators, rides horses bareback, and lives in a ramshackle cabin that she built herself in an island wilderness. She’s had three husbands and many lovers, one of whom she shot and killed in self-defense. A combination of Henry David Thoreau and Jane Goodall, Carol is a self-taught scientist who has become a tireless defender of sea turtles on Cumberland Island, a national park off the coast of Georgia.Cumberland is the country's largest and most biologically diverse barrier island—over forty square miles of pristine wilderness celebrated for its windswept dunes and feral horses. Steel magnate Thomas Carnegie owned much of Cumberland, and his widow Lucy made it a Gilded Age playground. But in recent years, Carnegie heirs and the National Park Service have clashed with Carol over the island’s future. What happens when a dirt-poor naturalist with only a high-school diploma tries to stop one of the wealthiest families in America? Untamed is the story of an American original standing her ground and fighting for what she believes in, no matter the cost.

    Hazen writes of how the co-evolution of the geosphere and biosphere—of rocks and living matter—has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth’s makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet’s many iterations in vivid detail. Through his theory of “co-evolution,” we learn how reactions between organic molecules and rock crystals may have generated Earth’s first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet.The Story of Earth is also the story of the pioneering men and women behind the sciences. Readers will meet black-market meteorite hawkers of the Sahara Desert, the gun-toting Feds who guarded the Apollo missions’ lunar dust, and the World War II Navy officer whose super-pressurized “bomb”—recycled from military hardware—first simulated the molten rock of Earth’s mantle. As a mentor to a new generation of scientists, Hazen introduces the intrepid young explorers whose dispatches from Earth’s harshest landscapes will revolutionize geology.
