Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

In Winter World: The Ingenuity of Animal Survival, biologist, illustrator, and award-winning author Bernd Heinrich explores his local woods, where he delights in the seemingly infinite feats of animal inventiveness he discovers there. Because winter drastically affects the most elemental component of all life---water---radical changes in a creature's physiology and behavior must take place to match the demands of the environment.

The Everglades was America's last frontier, a wild country long after the West was won. In this book Michael Grunwald chronicles how a series of visionaries tried to drain and "reclaim" it and how Mother Nature refused to bend to their will; in the most harrowing tale, a 1928 hurricane drowned 2,500 people in the Everglades. But the Army Corps of Engineers finally tamed the beast with levees and canals, converting half the Everglades into sprawling suburbs and sugar plantations.

In his main work, the best-selling Worlds in Collision, Immanuel Velikovsky gave a detailed reconstruction of two global natural catastrophes based on information handed down by our ancestors. He mentions there that, as part of his intensive research, he found numerous indications of even more catastrophes that took place earlier in the history of mankind.

For a thousand generations, human beings viewed themselves as part of the wider community of nature, and they carried on active relationships not only with other people but with other animals, plants, and natural objects (including mountains, rivers, winds, and weather patterns) that we have only lately come to think of as "inanimate". How, then, did humans come to sever their ancient reciprocity with the natural world?

Eating one's own kind is a completely natural behavior in thousands of species, including humans. Throughout history we have engaged in cannibalism for reasons related to famine, burial rites, and medicine. Cannibalism has also been used as a form of terrorism and as the ultimate expression of filial piety. With unexpected wit and a wealth of knowledge, Bill Schutt takes us on a tour of the field, exploring exciting new avenues of research and investigating questions like why so many fish eat their offspring and some amphibians consume their mothers' skin.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs' lives from their fossils - their colors, their growth, and even whether we will ever be able to bring them back to life.

Traditionally, Americans learned in school that the ancestors of the people who inhabited the Western Hemisphere at the time of Columbus' landing had crossed the Bering Strait 12,000 years ago; existed mainly in small nomadic bands; and lived so lightly on the land that the Americas were, for all practical purposes, still a vast wilderness. But as Charles C. Mann now makes clear, archaeologists and anthropologists have spent the last 30 years proving these and many other long-held assumptions wrong.

As development and subsequent habitat destruction accelerate, there are increasing pressures on wildlife populations. But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity. Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and this audio edition will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.

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.

A book to be listened to for pleasure as well as a practical identification guide, The Edge of the Sea introduces a world of teeming life where the sea meets the land. A new generation of listeners is discovering why Rachel Carson's books have become cornerstones of the environmental and conservation movements.

The problem of agriculture is as old as civilization. Throughout history, great societies that abused their land withered into poverty or disappeared entirely. Now we risk repeating this ancient story on a global scale due to ongoing soil degradation, a changing climate, and a rising population. But there is reason for hope. David R. Montgomery introduces us to farmers around the world at the heart of a brewing soil health revolution that could bring humanity's ailing soil back to life remarkably fast.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

A compelling history of seashells and the animals that make them, revealing what they have to tell us about nature, our changing oceans, and ourselves. Seashells have been the most coveted and collected of nature's creations since the dawn of humanity. They were money before coins, jewelry before gems, art before canvas. In The Sound of the Sea, acclaimed environmental author Cynthia Barnett blends cultural history and science to trace our long love affair with seashells and the hidden lives of the mollusks that make them.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

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.

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.
