Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

Despite efforts to sustain civilization, humanity faces existential threats from overpopulation, globalized trade and travel, urbanization, and global climate change. In A Darwinian Survival Guide, Daniel Brooks and Salvatore Agosta offer a novel—and hopeful—perspective on how to meet these tremendous challenges by changing the discourse from sustainability to survival. Darwinian evolution, the world’s only theory of survival, is the means by which the biosphere has persisted and renewed itself following past environmental perturbations, and it has never failed, they explain.

Evolutionary biologist Nathan H. Lents takes listeners on a journey from silent crickets to lesbian albatrosses to bonobos who kiss, revealing what this incredible array of sexual diversity can teach us about our own. Amusing, enlightening and meticulously researched, Lents convincingly shows that diverse genders and sexuality have evolutionary functions far beyond procreation. The Sexual Evolution is a perspective-altering book that advocates understanding and demolishes biases held by even the most open-minded among us.

In Forest Euphoria, Kaishian shows us this making of a scientist and introduces readers to the queerness, literal and otherwise, of all the life around us. Fungi, we learn, commonly have more than two biological sexes—and some as many as twenty-three thousand. Some intersex slugs mutually fire calcium carbonate “love darts” at each other during courtship.

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?

If forests are the lungs of the planet, then animals migrating across oceans, streams, and mountains—eating, pooping, and dying along the way—are its heart and arteries, pumping nitrogen and phosphorus from deep-sea gorges up to mountain peaks, from the Arctic to the Caribbean. Without this conveyor belt of crucial, life-sustaining nutrients, the world would look very different.

This Very Short Introduction takes listeners into the inferno of a racing pyroclastic current, and the heart of a moving lava flow, as understood through the latest scientific research. Exploring how volcanologists forensically decipher how volcanoes work, Michael Branney and Jan Zalasiewicz explain what we do (and don't) understand about the fundamental mechanisms of volcanism, and consider how volcanoes interact with other physical processes on the Earth, with life, and with human society.

At age sixteen Sophie Strand—bright, agile, fearless—is suddenly beset by unexplained, debilitating illness while on a family trip abroad. Her once vibrant life becomes a tangled miasma of medication, specialists, anaphylaxis, and seemingly never-ending attempts to explain what has gone so terribly wrong. And, for many years thereafter, Sophie's life becomes subsumed with ideas not of "health," but of explanation, and the narrative of how and why she became sick. But slowly, she comes to another, more fundamental understanding of what has happened to her body.

Renowned scientist Neil Shubin has made extraordinary discoveries by leading scientific expeditions to the sweeping ice landscapes of the Arctic and Antarctic. He’s survived polar storms, traveled in temperatures that can freeze flesh in seconds, and worked hundreds of miles from the nearest humans, all to deepen our understanding of our world. Written with infectious enthusiasm and irresistible curiosity, Ends of the Earth blends travel writing, science, and history in a book brimming with surprising and wonderful discoveries.

In 1934, the painter Christiane Ritter leaves her comfortable life in Austria and travels to the remote Arctic island of Spitsbergen, to spend a year there with her husband. She thinks it will be a relaxing trip, a chance to "read thick books in the remote quiet and, not least, sleep to my heart's content," but when Christiane arrives she is shocked to realize that they are to live in a tiny ramshackle hut on the shores of a lonely fjord, hundreds of miles from the nearest settlement, battling the elements every day, just to survive.

From the quiet beauty of sugar maple forests to the high-tech, high-stakes world of syrup production, this book takes you on a remarkable journey into one of Canada’s most cherished traditions. Led by Peter Kuitenbrouwer, a forester with a deep appreciation for the land, his narrative uncovers the rich Indigenous heritage of maple syrup, explores its cultural significance and reveals the complex industry that sustains it today, where vast warehouses store a product so valuable it became the target of the Great Maple Syrup Heist, one of Canada’s most infamous thefts.

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

In Of Orcas and Men, a marvelously compelling mix of cultural history, environmental reporting, and scientific research, David Neiwert explores an extraordinary species and its occasionally fraught relationship with human beings. Beginning with their role in myth and contemporary culture, Neiwert shows how killer whales came to capture our imaginations and brings to life the often-catastrophic environmental consequences of that appeal.

David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. When his specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake, many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation.

It is not your imagination: water crises are more frequent. Our twentieth-century systems for providing the water that grows food, sustains cities, and supports healthy ecosystems are failing to meet the demands of growing population and the challenges brought on by climate change. But the grim news reports—of empty reservoirs, withering crops, failing ecosystems—need not be cause for despair, argues award-winning author David Sedlak.

The Paris Accords, widely accepted as the key to solving today's climate crisis, set a goal of zero net carbon emissions by 2050. But that's not good enough. The only way to guarantee a livable future is climate restoration, which can reduce greenhouse gases to historic levels. Scientist and entrepreneur Peter Fiekowsky explains the technology and maps a practical path that will let humankind survive and thrive.

Biodiversity, the diversity of life, is not only fascinating and beautiful, it is the engine of all the world's natural cycles, and the source of many of the resources on which humanity depends. Concern about biodiversity conservation is, therefore, not merely the preoccupation of a few enthusiastic naturalists—it is the lifeline business of everybody.

When ecologist Carl Safina and his wife, Patricia, took in a near-death baby owl, they expected that, like other wild orphans they'd rescued, she'd be a temporary presence. But Alfie's feathers were not growing correctly, requiring prolonged care. As Alfie grew and gained strength, she became a part of the family, joining a menagerie of dogs and chickens and making a home for herself in the backyard.

Why Animals Talk is an exhilarating journey through the untamed world of animal communication.

From the majestic howls of wolves and the enchanting chatter of parrots to the melodic clicks of dolphins and the spirited grunts of chimpanzees, these diverse and seemingly bizarre expressions are far from mere noise. In fact, they hold secrets that we are just beginning to decipher.
