With predictions of a human population of more than nine billion by the middle of this century and 11 billion by 2100, we stand at a crossroads in our agricultural evolution. In this clear and engaging book, wildlife biologist John M. Marzluff takes a personal approach to sustainable agriculture. He travels to farms and ranches across North and Central America, including a Nebraska corn and soybean farm, California vineyards, cattle ranches in Montana, and small sustainable farms in Costa Rica, to understand the unique challenges and solutions to sustainable food production. 

Fruit flies, silverfish, dandelions, and crabgrass are the bane of many people and the target of numerous chemical and physical eradication efforts. In this compelling reassessment of the relationship between humans and the natural world, John Hainze - an entomologist and former pesticide developer - considers the fascinating and bizarre history of how these so-called invasive or unwanted pests and weeds have co-evolved with humanity and highlights the benefits of a greater respect and moral consideration toward these organisms.

Systems biology came about as growing numbers of engineers and scientists from other fields created algorithms which supported the analysis of biological data in incredible quantities. Whereas biologists of the past had been forced to study one item or aspect at a time, due to technical and biological limitations, it suddenly became possible to study biological phenomena within their natural contexts.

Our sense of smell - or olfaction as it is technically known - is our most enigmatic sense. It can conjure up memories, taking us back to very specific places and emotions, whilst powerful smells can induce strong feelings of hunger or nausea. In the animal kingdom smell can be used to find food, a mate, or a home; to sense danger; and to send and receive complex messages with other members of a species. Yet despite its fundamental importance in our mental life and in the existence of all animals, our scientific understanding of how smell works is limited.

In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we've learned of these key migrations is nothing short of extraordinary. This breathtaking work of nature writing also introduces listeners to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.

For nearly 80 years, a huge portion of coastal South Africa was closed off to the public. With many of its pits now deemed "overmined" and abandoned, American journalist Matthew Gavin Frank sets out across the infamous Diamond Coast to investigate an illicit trade that supplies a global market. Immediately, he became intrigued by the ingenious methods used in facilitating smuggling - particularly, the illegal act of sneaking carrier pigeons onto mine property, affixing diamonds to their feet, and sending them into the air.

In the late 19th century, as humans came to realize that our rapidly industrializing and globalizing societies were driving other animal species to extinction, a movement to protect and conserve them was born. In Beloved Beasts, acclaimed science journalist Michelle Nijhuis traces the movement's history: from early battles to save charismatic species such as the American bison and bald eagle to today's global effort to defend life on a larger scale.

There is more than one way for animals to prepare for winter. Some, such as mice, foxes, and moose, simply tolerate the cold. Of course, black bears hibernate, but chipmunks, wood frogs, and garter snakes do, too. And then there are the creatures that migrate, including hummingbirds, blue whales, and even earthworms! 

At the start of this remarkable story of recovery, healing, and redemption, Ginger Gaffney answers a call to help retrain the troubled horses at an alternative prison ranch in New Mexico, a facility run entirely by the prisoners. The horses are scavenging through the dumpsters, kicking and running down the residents when they bring the trash out after meals. One horse is severely injured. The horses and residents arrive at the ranch broken in one way or many: the horses are defensive and terrified, while the residents, some battling addictions, are emotionally and physically shattered.

Instead of a great island of trash, the infamous Great Pacific Garbage Patch is made up of manmade debris spread over hundreds of miles of sea - more like a soup than a floating garbage dump. Recycling is more complicated than we were taught: Less than nine percent of the plastic we create is reused, and the majority ends up in the ocean. And plastic pollution isn’t confined to the open sea: It’s in much of the air we breathe and the food we eat.

Teeming with unsuspected life, an extraordinary, interconnected ecosystem deep below the waves has a huge effect on our daily lives, influencing climate and weather systems, with the potential for much more—good or bad, depending on how it is exploited. Currently, the fantastic creatures that live in the deep—many of them incandescent in a world without light—and its formations capture and trap vast quantities of carbon that would otherwise poison our atmosphere, and novel bacteria as yet undiscovered hold the promise of potent new medicines.

A century ago, mountain lions were vilified as a threat to livestock and hunted to the verge of extinction. Its recovery has led to an unexpected conundrum: Do more mountain lions mean they're a threat to humans and domestic animals? Or, are mountain lions still in need of our help and protection as their habitat dwindles? Mountain lion biologist and expert Mark Elbroch welcomes these tough questions. He dismisses long-held myths about mountain lions and uses groundbreaking science to uncover important new information about their social habits.

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.

A lifetime of adventures with bats around the world reveals why these special and imperiled creatures should be protected rather than feared.

Walter Tschinkel has spent much of his career investigating the hidden subterranean realm of ant nests. This book takes you inside an unseen world where thousands of ants build intricate homes in the soil beneath our feet. Tschinkel describes the ingenious methods he has devised to study ant nests, showing how he fills a nest with plaster, molten metal, or wax and painstakingly excavates the cast.

On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them, and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous.
