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.

This Very Short Introduction audiobook explores amphibians' evolution, adaptations, and biology, from the first emergence of tetrapods onto land 370 million years ago, to how their permeable skin enables them to thrive in their habitat today. T. S. Kemp describes how different amphibians go about their lives, looking in particular at their complex courtship behavior and their extraordinary means of providing care for their eggs and larvae.

Growing up in California, J. Craig Venter didn't appear to have much of a future. An unremarkable student, he nearly flunked out of high school. After being drafted into the army, he enlisted in the Navy and went to Vietnam, where the life-and-death struggles he encountered as a medic piqued his interest in science and medicine. After pursuing his advanced degrees, Venter quickly established himself as a brilliant and outspoken scientist.

Since its formation nearly five billion years ago, our planet has been the sole living world in a vast and silent universe. Now, Earth's isolation is coming to an end. Over the past two decades, astronomers have discovered thousands of "exoplanets" orbiting other stars, including some that could be similar to our own world. Studying those distant planets for signs of life will be crucial to understanding life's intricate mysteries right here on Earth. In a firsthand account of this unfolding revolution, Lee Billings draws on interviews with top researchers.

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 Accidental Ecosystem tells the story of how cities across the United States went from having little wildlife to filling, dramatically and unexpectedly, with wild creatures. Today, many of these cities have more wild animals living in them than at any time in at least the past 150 years. Why have so many cities—the most artificial and human-dominated of all Earth's ecosystems—grown rich with wildlife, even as wildlife has declined in most of the rest of the world? And what does this paradox mean for people, wildlife, and nature on our increasingly urban planet?

To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139µm, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans.

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.

The carbon dioxide that industrial civilization spews into the atmosphere has dramatic consequences for life on Earth that extend beyond climate change. CO2 levels directly affect plant growth, in turn affecting any kind of life that depends on plants—in other words, everything.

Nineteen leading literary writers from around the globe offer timely, haunting first-person reflections on how climate change has altered their lives.

Bacteria form a fundamental branch of life. They are the oldest forms of life and the most prolific of all living organisms, inhabiting every part of the Earth's surface, its ocean depths, and even such inhospitable places as boiling hot springs. In this Very Short Introduction, bacteriologist Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease.

We think we know photosynthesis: Plants convert of sunlight, CO2, and water into energy and, ultimately, the food we eat and air we breathe. But Raffael Jovine shows how this incredible process goes beyond what we learned in grade school. First, it's not only about plants: Corals partner with photosynthetic organisms to create the most productive habitat on Earth, slugs eat chloroplasts to create a photosynthesis-based camouflage, hornets use photosynthesis for a very unconventional form of air conditioning—and much more!

From sheepdogs to wombats to coyotes to jellyfish, animals serve important biological roles in the world. But those who love animals know there's more. We know our connection to other creatures is more than fur, scale, or feather deep. In Saints of Feather and Fang, writer and lifelong animal lover Caryn Rivadeneira looks at the ways that animals—from the pets who share our homes to the mysterious creatures of the deep—serve as spiritual guides for our hearts, minds, and souls. In them we discover and connect with the God who beckons, rescues, and shelters us.

In Extinction and the Human, Timothy Sweet ponders the realities of animal extinction and endangerment and the often divergent Native American and Euro-American narratives that surround them. He focuses especially on the force of human impact on megafauna—mammoths, whales, and the North American bison. Ultimately, he argues, it is the critical assessment of ideas of human exceptionalism that provides a necessary counterpoint both to apologies for human mastery over nature and deep ecology's attempts to erase the human.

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.

The history of the ubiquitous pine tree is wrapped up with the history of early America - and in the hands of a gifted storyteller becomes a compelling listen, almost an adventure story.

For many people, ecosystems may be a remote concept, yet we eat, drink, breathe and interface with them in every moment of our lives. In this engaging textbook, ecosystems scientist Dr. Mark Everard considers a diversity of "everyday things", including fascinating facts about their ecological origins: from the tea we drink, to the things we wear, read, and enjoy, to the ecology of communities and space flight, and the important roles played by germs and "unappealing creatures" such as slugs and wasps.
