A heady blend of international intrigue, social theory, botanical lore, and ecological study, The Cactus Hunters offers complex insight into species extinction, conservation, and more-than-human care.

Among scientists who write, no one illuminates as well as Stephen Jay Gould does the wonderful workings of the natural world. Now in a new volume of collected essays—his sixth since Ever Since Darwin—Gould speaks of the importance of unbroken connections within our own lives and to our ancestral generations. Along with way, he opens to us the mysteries of fish tails, frog calls, and other matters, and shows once and for all why we must take notice when a seemingly insignificant creature is threatened, like the land snail Partula from Moorea, whose extinction he movingly relates.

Not everyone can become a tyrant. It requires a particular confluence of events to gain absolute control over entire nations. First, you must be born with the potential to develop brutal personality traits. Second, your predisposition to antisocial behavior must be developed and strengthened during childhood. Finally, you must come of age when the political system of your country is unstable.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

Most people know Ted Danson as the affable bartender Sam Malone in the long-running television series Cheers. But fewer realize that over the course of the past two and a half decades, Danson has tirelessly devoted himself to the cause of heading off a looming global catastrophe---the massive destruction of our planet's oceanic biosystems and the complete collapse of the world's major commercial fisheries.

The American buffalo-our nation's official mammal-is an improbable, shaggy beast that has found itself at the center of many of our most mythic and sometimes heartbreaking tales. The largest land animals in the Western Hemisphere, they are survivors of a mass extinction that erased ancient species that were even larger. For nearly 10,000 years, they evolved alongside Native people who weaved them into every aspect of daily life; relied on them for food, clothing, and shelter; and revered them as equals.

Each of us began life as a single cell. From this humble origin, we embarked on a risky journey fraught with opportunities for disaster. Yet, amazingly, we reached our destination intact, emerging as dazzlingly complex, exquisitely engineered assemblages of trillions of cells. This metamorphosis constitutes one of nature's most spectacular yet commonplace magic tricks—and one of its most coveted secrets. In From One Cell, physician and researcher Ben Stanger offers a glimpse into what scientists are discovering about how life and the body take shape.

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.

Life innovates constantly, producing perfectly adapted species—but there's a catch. Many animals and plants eke out seemingly unremarkable lives. Passive, constrained, modest, threatened. Then, in a blink of evolutionary time, they flourish spectacularly. Once we start to look, these 'sleeping beauties' crop up everywhere. But why? Looking at the book of life, from apex predators to keystone crops, and informed by his own cutting-edge experiments, renowned scientist Andreas Wagner demonstrates that innovations can come frequently and cheaply to nature, well before they are needed.

A plastic box with a lightbulb attached may seem like an odd birthday present. But for ecologist Tim Blackburn, a moth trap is a captivating window into the world beyond the roof terrace of his London flat. Whether gaudy or drab, rare or common, each moth ensnared by the trap is a treasure with a story to tell. In The Jewel Box, Blackburn introduces these mysterious visitors, revealing how the moths he catches reflect hidden patterns governing the world around us.

In Changing How We Choose, David Redish makes a bold claim: science has "cracked" the problem of morality. Redish argues that moral questions have a scientific basis, and that morality is best viewed as a technology—a set of social and institutional forces that create communities and drive cooperation. This means that some moral structures are better than others and that the moral technologies we use have real consequences on whether we make our societies better or worse places for the people living within them.

Today ten times more tigers live in captivity than survive in the wild. For over five decades, K. Ullas Karanth has been engaged in the struggle to bring wild tigers back from the brink in India, their last remaining wild stronghold. He tells the story of the tiger itself—its incredible biology, its critical role in shaping natural ecosystems of Asia, and the unique place it holds in our collective imagination. Among Tigers is the story of how we wound up with fewer than 5,000 wild tigers, and how, with focused efforts, we can grow that population ten times or more in a few decades.

Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later.

Zoologist Jo Wimpenny turns a critical eye to Aesop's fables to discover whether there is any scientific truth to their portrayal of the animal kingdom. She brings the tales into the twenty-first century, introducing the latest findings on the most fascinating branches of ethological research—the study of why animals do the things they do. In each chapter she interrogates a classic fable and a different topic—future planning, tool use, self-recognition, cooperation and deception—concluding with a verdict on the veracity of each fable's portrayal from a scientific perspective.

"Lively writing about science and nature depends less on the offering of good answers, I think, than on the offering of good questions," said David Quammen in the original introduction to Natural Acts. For more than two decades, he has stuck to that credo. In this updated version of Natural Acts, curiosity leads him from New Mexico to Romania, from the Congo to the Amazon, asking questions about mosquitoes (what are their redeeming merits?), dinosaurs (how did they change the life of a dyslexic Vietnam vet?), and cloning (can it save endangered species?).

Birds are a joy and solace in troubled times, as well as a reminder of past experiences and a symbol of hope for the future. For centuries, they were also seen as a source of food, feathers, and even fuel, and being so numerous many were persecuted as pests. When There Were Birds is a social history of Britain that charts the complex connections between people and birds, set against a background of change. No other group of animals has had such a complex relationship with humankind.

Stephanie D. Preston explores how and why we developed a surprisingly powerful drive to help the vulnerable. She argues that the neural and psychological mechanisms that evolved to safeguard offspring also motivate people to save strangers in need of immediate aid. Merging extensive interdisciplinary research that spans psychology, neuroscience, neurobiology, and evolutionary biology, Preston develops a groundbreaking model of altruistic responses.

When the birds first called, Susan Fox Rogers was in a slack season of her life. The woods and rivers that enthralled her younger self had lost some of their luster. It was the song of a thrush that reawakened Rogers, sparking a long-held desire to know the birds that accompanied her as she rock climbed and paddled, to know the world around her with greater depth. Energized by her curiosity, she followed the birds as they drew her deeper into her authentic self, and ultimately into love.

One day in 1996, the neuroscientist Eric R. Kandel took a call from his program officer at the National Institute of Mental Health, who informed him that he had been awarded a key grant. Also, the officer said, he and his colleagues thought Kandel would win the Nobel Prize. "I hope not soon," Kandel's wife, Denise, said when she heard this. Sociologists had found that Nobel Prize winners often did not contribute much more to science, she explained.

With its rich biodiversity, astounding wildlife, and breathtaking animal migrations, Serengeti is like no other ecosystem on the planet. A Place Like No Other is Anthony Sinclair's firsthand account of how he and other scientists discovered the biological principles that regulate life in Serengeti and how they rule all of the natural world.
