Ecosystem Science

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.

Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.

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.

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

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.

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.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

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.

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 The Secret Wisdom of Nature, master storyteller and international sensation Peter Wohlleben takes listeners on a thought-provoking exploration of the vast natural systems that make life on Earth possible. In this tour of an almost unfathomable world, Wohlleben describes the fascinating interplay between animals and plants.

To celebrate the 40th anniversary of the book’s first publication, David Attenborough has revisited Life on Earth, completely updating and adding to the original text, taking account of modern scientific discoveries from around the globe....

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

Only those who love trees should cut them, writes forester Ethan Tapper. In How to Love a Forest, he asks what it means to live in a time in which ecosystems are in retreat and extinctions rattle the bones of the earth. How do we respond to the harmful legacies of the past? How do we use our species’ incredible power to heal rather than to harm? Tapper walks us through the fragile and resilient community that is a forest.

Microbiology for Dummies is your guide to understanding the fundamentals of this enormously-encompassing field. Whether your career plans include microbiology or another science or health specialty, you need to understand life at the cellular level before you can understand anything on the macro scale. Microbes are literally the foundation of all life, and they are everywhere. Microbiology for Dummies will help you understand them, appreciate them, and use them.

From bestselling author, long-time former National Geographic Explorer, and anthropologist Wade Davis comes the story of America's Nile: how it once flowed freely and how human intervention has left it near exhaustion, altering the water temperature, volume, local species, and shoreline of the river Theodore Roosevelt once urged us to "leave it as it is."

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?

Our world is changing, the climate is changing. Species that have long existed on our planet are disappearing and resources are becoming scarce. People are slowly realizing that development is not always good. We are exploiting our earth, but we should be looking after it, because we only have this one. Slowly, however, a rethink is taking place and people are trying to undo past mistakes. Attempts are being made to reduce CO₂ emissions, conserve the earth's resources and pay more attention to nature. But once we have become accustomed to a certain standard of living, it is difficult to give it up again or change our habits.

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.
