When the sun has set, things get interesting with wild animals. Where people wait for buses during the day, a family of raccoons rummages through the trash can. Foxes and skunks search for food; fireflies send flashing signals to potential mates; owls and bats fly overhead. Night is not just a time, but a diverse habitat that we still know too little about. Wildlife biologist Sophia Kimmig is on the trail of the secrets of the night.

Mysterious, graceful, and ever-clever, otters have captivated our imaginations, despite the fact that few people have encountered one in the wild. In Otter Country, celebrated nature writer Miriam Darlington captures the fascination she's had for these playful animals since childhood, and chronicles her immersive journey into their watery world. Over the course of a single year, Darlington takes listeners on a winding expedition in pursuit of these elusive creatures—from her home in Devon, England, and through the wilds of Scotland, Wales, the Lake District, and the countryside of Cornwal

Understanding Nature is a new kind of ecology textbook: a straightforward resource that teaches natural history and ecological content, and a way to instruct students that will nurture both Earth and self. While meeting the textbook guidelines set forth by the Ecological Society of America, Understanding Nature has a unique ecotherapy theme, using a historical framework to teach ecological theory to undergraduates.

In The Other Big Bang, the evolutionary and developmental biologist Eric S. Haag explores the two-billion-year history of sex, from the first organisms on Earth to contemporary humans.

Nature writer David Gessner chronicles the year-long odyssey of Flaco, the Eurasian eagle-owl who escaped from Central Park Zoo and captured the hearts and imaginations of millions of followers around the world. Though he'd spent his life in a cage, Flaco learned to survive in New York City by eating rats, squirrels, and birds. He was an immigrant coming from elsewhere to make it in the big city. Central Park, the island of green in an urban sea, was his new home territory.

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.

Well-meaning physicians, parents, and even scientists today often spread misinformation about what biology can and can't tell us about our bodies, minds, and identities. In this accessible, myth-busting book, geneticist Shoumita Dasgupta draws on the latest science to correct common misconceptions about how much of our social identities are actually based in genetics.

Over the course of his career, Hal Borland wrote eight nature books and hundreds of "outdoor editorials" for the Sunday New York Times, extolling the virtues of the countryside. From his home on one hundred acres in rural Connecticut, Borland wrote of the natural wonders, both big and small, that surrounded him every day. Beyond Your Doorstep is his guide to venturing into the outdoors around your home, wherever it is, and discovering the countryside within reach.

Earth stands at a tipping point. As we fail to curtail emissions fast enough, our planet stares down a cascade of imminent, catastrophic, and irreversible disaster triggered by climate change. Yet a potent technology already exists to buy us more time: solar geoengineering. Through methods such as atmospheric aerosols, human-generated cirrus clouds, and solar sails, we humans can—at least in the short term—slow the Earth's warming. Should we?

So begins this lively collection of essays by acclaimed filmmaker and novelist Priyanka Kumar. Growing up at the feet of the Himalayas in northern India, Kumar took for granted her immersion in a lush natural world. After moving to North America as a teenager, she found herself increasingly distanced from more than human life and discouraged by the civilization she saw contributing to its destruction. It was only in her twenties, living in Los Angeles and working on films, that she began to rediscover her place in the landscape-and in the cosmos—by way of watching birds.

We are all familiar with the "march of progress," the representation of evolution that depicts a series of apelike creatures becoming progressively taller and more erect before finally reaching the upright human form. Its emphasis on linear progress has had a decisive impact on public understanding of evolution, yet the image contradicts modern scientific conceptions of evolution as complex and branching.

After the extinction of the dodo and Carolina parakeet and the collapse of the American bison population, naturalists expected many more vulnerable species to die out with spread of industrialization. This triggered a race to collect rare species of animals expected soon to be lost forever. Established in 1893, Chicago's Field Museum aimed to become a global center of study. Zoologist Daniel Giraud Elliot persuaded museum patrons to fund an immediate expedition to British Somaliland (contemporary Somalia). There, his team hunted and killed hundreds of animals for the growing collection.

Across the world, invasive species pose a danger to ecosystems. The UN Convention on Biological Diversity ranks them as a major threat to biodiversity on par with habitat loss, climate change, and pollution. Tackling this isn't easy, and no one knows this better than Hugh Warwick, a conservationist who loathes the idea of killing, harming, or even eating animals. Yet as an ecologist, he is acutely aware of the need, at times, to kill invasive species whose presence harms the wider environment.

The Monarch Butterfly Migration focuses a wider lens on the effects of climate change and the tensions between advocacy and scientific accuracy. This book reminds us to notice the natural wonders in our own backyards.

In nature, everything is connected: from microscopic bacteria and soaring trees to animals struggling for survival amid thriving humanity. Yet many of today's toughest problems, from environmental destruction to divisive politics, stem from fundamental disconnections. In Intertwined, Michael Gross explains how the natural world can be a powerful reminder of our interdependence.

Experts agree on the value of genetic testing when there is a family history of disease, or if the patient has an illness frequently caused by a mutation. Knowing the disease mutation lets family members find out if they have it too and need preventive care. The book explains that doctors can order tests with genetic counseling at relatively low cost and how this will help them prescribe preventive actions, make earlier diagnoses, and get better outcomes.

What is our immune system, and how does it work? A vast array of cells, proteins and chemicals spring into action whenever our bodies are damaged, but immunity is not something you can see, touch, or feel. It can fight off malicious bacteria and viruses, locate cancerous growths, and even rewire our brains—but sometimes our own tissues can get caught in its crossfire, with catastrophic consequences. Humans may be the most disease-ridden animals on the planet. Professor John Trowsdale shows how the immune system protects us, and how our bodies invest huge resources to keep it running.
