This volume, aimed at the general audience, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies.

Coyote America is both an environmental and a deep natural history of the coyote. It traces both the five-million-year-long biological story of an animal that has become the "wolf" in our backyards and its cultural evolution from a preeminent spot in Native American religions to the hapless foil of the Road Runner. A deeply American tale, the story of the coyote in the American West and beyond is a sort of Manifest Destiny in reverse.

For those who have a disdain for birds or bird lovers with a sense of humor, this snarky handbook is equal parts profane, funny, and—let's face it—true. Featuring common North American birds, such as the White-Breasted Butt Nugget and the Goddamned Canada Goose (or White-Breasted Nuthatch and Canada Goose for the layperson), Matt Kracht identifies all the idiots in your backyard and details exactly why they suck. With The Field Guide to Dumb Birds of North America, you won't need to wonder what all that racket is anymore!

When Dr. David Hosack tilled the country's first botanical garden in the Manhattan soil more than 200 years ago, he didn't just dramatically alter the New York landscape; he left a monumental legacy of advocacy for public health and wide-ranging support for the sciences. In melodic prose, historian Victoria Johnson eloquently chronicles Hosack's tireless career to reveal the breadth of his impact. The result is a lush portrait of the man who gave voice to a new, deeply American understanding of the powers and perils of nature.

Oliver Sacks is well known as an explorer of the human mind - a neurologist with a gift for complex, insightful portrayals of people and their conditions. However, he is also a card-carrying member of the American Fern Society, and since childhood has been fascinated by these primitive plants and their ability to survive and adapt in many climates. Oaxaca Journal is Sacks' spellbinding account of his trip with a group of fellow fern enthusiasts to the beautiful, history-steeped province of Oaxaca, Mexico.

Here is the epic history of the "iron men in wooden boats" who built an industrial empire through the pursuit of whales. This absorbing history demonstrates that few things can capture the sheer danger and desperation of men on the deep sea as dramatically as whaling. This sweeping social and economic history provides rich and often fantastic accounts of the men themselves, who mutinied, murdered, rioted, deserted, drank, scrimshawed, and recorded their experiences in journals and memoirs.

La Ruota di Medicina degli indiani d'America è la Ruota della Natura e racchiude in sé l'intera cultura e le tradizioni dei nativi americani: è la simbolica testimonianza della loro spiritualità, del rapporto vivo e vero che essi intrattengono da sempre con la natura. La Ruota di medicina ci fa scoprire che la natura non è un oggetto al nostro servizio, ma un sistema complesso e vivente che continuamente si trasforma, i cui equilibri dipendono anche da noi e dal nostro comportamento quotidiano nei suoi confronti.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

Journalist Marguerite Holloway arrives at the Women's Tree Climbing Workshop as a climbing novice, but with a passion for trees and a deep concern about their future. Run by twin sister tree doctors Bear LeVangie and Melissa LeVangie Ingersoll, the workshop helps people develop impressive technical skills and ascend into the canopy.

From the colonial era through the mid-twentieth century, America's flocks played a key role in the nation's development. Furthermore, much consternation centered around the sheep the United States lacked, so that dependency on foreign wool became a full-blown crisis in wartime. But more than just providers of wool, sheep were valued for their meat, for their byproducts after slaughter, and even for their efficiency at lawn maintenance.

Rabies enjoys a fearsome and lurid reputation. Throughout the decades of spiraling growth that defined New York City from the 1840s to the 1910s, the bone-chilling cry of "Mad dog!" possessed the power to upend the ordinary routines and rhythms of urban life. In Mad Dogs and Other New Yorkers, Jessica Wang examines the history of this rare but dreaded affliction during a time of rapid urbanization.

Few fish are as beloved, or as obsessed over, as the American shad. Although shad spend most of their lives in salt water, they enter rivers by the hundreds of thousands in the spring and swim upstream heroic distances in order to spawn, then return to the ocean.

In this Pulitzer Prize-finalist biography, the author of Mad at the World examines the little-known life of the man behind the well-known bird survey.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.

Having worked on numerous high-profile genetic investigations, including one focused on the famed Iceman of the Italian Alps, Bryan Sykes has become a premier authority on human genetics. In DNA USA, Sykes examines the unique fabric of the population of the United States - one of the world’s most genetically variegated countries. His fascinating discoveries offer new insights into the biological profile of the great melting pot.

The smog beast wafted into downtown Los Angeles on July 26, 1943. Nobody knew what it was. Secretaries rubbed their eyes. Traffic cops seemed to disappear in the mysterious haze. Were Japanese saboteurs responsible? A reckless factory? The truth was much worse - it came from within, from Southern California's burgeoning car-addicted, suburban lifestyle. Smogtown is the story of pollution, progress, and how an optimistic people confronted the epic struggle against airborne poisons barraging their hometowns.

The Galápagos archipelago is often viewed as a last foothold of pristine nature. For 60 years, conservationists have worked to restore this evolutionary Eden after centuries of exploitation at the hands of pirates, whalers, and island settlers. This book tells the story of the islands' namesakes - the giant tortoises - as coveted food sources, objects of natural history, and famous icons of conservation and tourism. By doing so, it brings into stark relief the paradoxical, and impossible, goal of conserving species by trying to restore a past state of prehistoric evolution.

In a tradition that runs from John Muir to Bear Grylls, Searles finds a fellowship with nature and a deeper meaning in the world of bears. Do bears understand things we don't? Are they dialed in to some greater natural force? Unlike us, bears waste little time on unreasonable fears. Bears are fully in the moment. They have an inner peace that seems to offset their power and strength. That may explain why no other animal on the planet is as revered as the bear.

In Birding Under the Influence, Dorian Anderson, a neuroscience researcher on a pressure-filled life trajectory, walks away from the world of elite institutions, research labs, and academic publishing. In doing so, he falls in love and discovers he has freed himself to embrace his lifelong passion for birding.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans.
