    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    The story of a lifetime of such minute explorations, For Love of Insects celebrates the small creatures that have emerged triumphant on the planet, the beneficiaries of extraordinary evolutionary inventiveness and unparalleled reproductive capacity. Eisner tells us, but never has a reckoning been such a pleasure. Recounting exploits and discoveries in his laboratory at Cornell and in the field in Uruguay, Australia, Panama, Europe and North America, Eisner time and again demonstrates how inquiry into the survival strategies of an insect leads to clarifications beyond the expected; insects are revealed as masters of achievement, forms of life worthy of study and respect from even the most recalcitrant entomophobe. Filled with descriptions of his ingenious experiments and illustrated with photographs, this book makes readers participants in the grand adventure of discovery on a scale infinitesimally small and infinitely surprising.

    Wilson recalls his lifetime with ants, from his first boyhood encounters in the woods of Alabama to perilous journeys into the Brazilian rainforest.“Ants are the most warlike of all animals, with colony pitted against colony,” writes E.O. Wilson, one of the world’s most beloved scientists, “their clashes dwarf Waterloo and Gettysburg.” In Tales from the Ant World, two-time Pulitzer Prize-winner Wilson takes us on a myrmecological tour to such far-flung destinations as Mozambique and New Guinea, the Gulf of Mexico’s Dauphin Island and even his parent’s overgrown backyard, thrillingly relating his nine-decade-long scientific obsession with over 15,000 ant species.Animating his scientific observations with illuminating personal stories, Wilson hones in on twenty-five ant species to explain how these genetically superior creatures talk, smell, and taste, and more significantly, how they fight to determine who is dominant. Wryly observing that “males are little more than flying sperm missiles” or that ants send their “little old ladies into battle,” Wilson eloquently relays his brushes with fire, army, and leafcutter ants, as well as more exotic species. Among them are the very rare Matabele, Africa’s fiercest warrior ants, whose female hunters can carry up to fifteen termites in their jaw (and, as Wilson reports from personal experience, have an incredibly painful stinger); Costa Rica’s Basiceros, the slowest of all ants; and New Caledonia’s Bull Ants, the most endangered of them all, which Wilson discovered in 2011 after over twenty years of presumed extinction.Richly illustrated throughout with depictions of ant species by Kristen Orr, as well as photos from Wilsons’ expeditions throughout the world, Tales from the Ant World is a fascinating, if not occasionally hair-raising, personal account by one of our greatest scientists and a necessary volume for any lover of the natural world.

    Experienced birders use the most easily observed characteristics — size, structure, behavior, and general color patterns — to identify birds even before looking carefully at plumage details. Now birders at all levels can learn how to identify shorebirds quickly and simply. This guide includes more than 870 stunning color photographs, starting with a general impression of the species and progressing to more detailed images of the bird throughout its life cycle. Quiz questions in the captions will engage and challenge all birders and help them benefit from this simplified, commonsense approach to identification.

    Accompanying range maps; overhead flight silhouettes; and sections on bird-watching, accidental species, and endangered birds make the National Audubon Society's Field Guide to North American Birds the most comprehensive available.Note: The Western Edition covers the Rocky Mountain range and all the states to the west of it, while the Eastern Edition generally covers states east of the Rocky Mountains.

    That word is formication, and the implied sense of horror and fascination, contends Richard Conniff, is something many of us actually crave. His Spineless Wonders presents an unabashed wallow in the joy of formication. Spineless Wonders is an engaging, sophisticated, and humorous mix of natural history and human lore. Through his journalistic assignments, Richard Conniff has been in contact with invertebrates for more than twenty years - tarantulas in the upper Amazon region, dragonflies in Arizona, squid in Florida, and flies on the rim of his beer glass. Discoveries about the extraordinary habits and idiosyncrasies of the moth, the leech, the ant, and the slime eel are opening new frontiers in the exploration of our natural universe. Spineless Wonders takes us directly to these wild and wonderful outposts to observe the hazards of being around invertebrates, the bizarre adaptions that enable them to survive in the world, and also the astonishing work they do - work that enables us to survive.

    This edition shows readers how to experience the wonders of the world and what creatures live in each habitat.
