One Species at a Time
The story of Earth's biodiversity from the Encylopedia of Life.
Lend an ear and discover the wonders of nature—right outside your back door and halfway around the world. In our new season of audio broadcasts, we’ll be learning about life as small as yeast and as big as a bowhead whale. Hear people's stories about nature and hone your backyard observation skills. We’ll be exploring the diversity of life—five minutes and One Species at a Time. Listen to us online, or download us and take us with you on your own exploration of the world around you. Brought to you by the Encyclopedia of Life and Atlantic Public Media.
The host and producer is Ari Daniel Shapiro. Jay Allison and Viki Merrick edit.
One Species at a Time, formerly the Podcast of Life, is heard every second Monday on WCAI: during Morning Edition at 8:30 and afternoons during All Things Considered at 5:30.
Tulips
LISTEN
When you think of the tools of the modern geneticist, the lowly razor blade probably don’t come to mind. But this low-tech tool is essential to the work of Dutch geneticist and passionate gardener Ron Zonneveld, who is using it to tease apart the genetic secrets of the flower whose spectacular genetic variation caused “tulip mania” in the 1600s and has made it a star in the genetics lab in the twenty-first century. Ari Daniel Shapiro reports from Leiden, the Netherlands.

Fungi
LISTEN
Hypholoma fasciculare and Amanita brunnescens
This week’s podcast begins with a riddle about a life form that’s all around us, yet rarely seen. Working under cover, it sends its ghostly tendrils into almost every corner of the terrestrial world. We associate it with death and decay, but life as we know it would be impossible without it. Come for a walk in the woods with Ari Daniel Shapiro and learn how this mysterious form of life, neither animal nor vegetable, shapes our world.

Marabou Stork
LISTEN
The marabou stork of southern Africa isn’t much to look at—it’s large, ungainly, and bald like a vulture, with a nasty appetite for carrion. This bird is increasingly making a home in urban areas like the Ugandan capital of Kampala, where human city dwellers don’t much like the habits of these winged neighbors. But graduate student Lillian Twanza has been studying the storks, with growing respect. She tells Ari Daniel Shapiro the ways that people have unknowingly put out the welcome mat for these scavengers.

Corpse Flowers
LISTEN
Let’s face it—when you think of charismatic megaflora, chances are you have in mind something majestic, like a towering Sequoia, or something ancient, like a Joshua tree. But a plant with a four-foot stalk that smells like a cross between rotting stinky cheese and animal feces? This week’s podcast takes us to a sacred island off the coast of Madagascar, where an intrepid botanist braved fever and worse to bring a specimen of this unlikely botanical superstar back alive. Ari Daniel Shapiro reports.

Arctic Tern
LISTEN
The arctic tern makes an incredible migration each year. These small birds travel distances of more than 50,000 miles, from pole to pole, crossing through temperate and tropical regions along the way. Carsten Egevang used geo-locator tags to track some of these terns, and he shares their story with us in this tour.

Midas Fly
LISTEN
Cresting a red sand dune, you come upon an unexpected sight in the desert: a shimmering expanse of fresh water. This oasis is no mirage, but a lake accidentally created by waste water from a desalination plant serving the growing city of Al Ain. The lake has brought change to the creatures, like the mydas fly, that are adapted to life in this stark and beautiful landscape. Ari Daniel Shapiro reports this cautionary tale from the United Arab Emirates.

Starlings
LISTEN
This week, we hear a story in two acts about a very familiar bird—the common starling. It's a non-native species that is omnivorous, gregarious, adaptable, and highly successful in its adopted land. It turns out we humans have inadvertently put out the welcome mat for this alien species. Act One tells the story about this winged invader with an $800 million appetite for fruit crops. As for Act Two, we’ll let independent producer Josh Kurz and the theater troupe Higher Mammals explain.

Ugandan Butterflies
LISTEN
Ugandan lepidopterist Perpetra Akite studies at a university in the capital city, far from the farm where she grew up. Since she began studying butterflies as a girl, the landscape of her homeland has changed radically, for butterflies as well as people. It’s change that can be measured in many ways—in the inches of rainfall, acres of forest cleared—or the span of a tiny butterfly’s wings. Ari Daniel Shapiro reports from Kigale.

Mangroves
LISTEN
Follow researchers Candy Feller and Dennis Whigham as they scramble, climb, crawl, and creep through the tangled roots of a mangrove forest. Along the way, learn what’s threatening these unique ecosystems where the ocean meets the land. Studying these flooded forests is a challenge, but pursuing science in this strange landscape has its own rewards.

Sanibel Shells
LISTEN
Ari Daniel Shapiro joins the serious beachcombers along the high-tide line of Sanibel Island, Florida. These “shellers” come in search of beautiful sea shells, sometimes no bigger than a grain of rice, that are the remains of marine snails, bivalves, and other mollusks. Along the way, Ari learns why Sanibel’s shores are so rich in molluscan treasure, and how shelling has captured the imaginations of scientists and enthusiasts alike.

Chinook Salmon
Can painted wooden fish on a schoolyard fence change human behavior and help clean up the ocean for the real salmon? Stream of Dreams in British Columbia thinks so, and a lot of wooden fish and some 100,000 school kids later, they have some intriguing results to show for their effort.

Sea Grapes Google Earth Tour
Caulerpa racemosa variety cylindracea
“Sea grapes” may sound like something Poseidon would snack on, and not a killer algae. Yet Caulerpa racemosa var. cylindracea poses a serious threat to marine life. Spread by the bilge water of boats, this fast-growing alga is quick to take root, squeezing out native species. But there is one spot in the Mediterranean where cylindracea hasn’t yet taken over, and biologists like Juan Manuel Ruiz Fernández are trying to discover why.

Greenland Shark
Join shark expert Greg Skomal as he ventures under the Arctic ice in search of the Greenland shark. Sharing this icy, blue twilight with an apex predator is a thrill--so long as you don’t end up being mistaken for a ringed seal, the shark’s favorite meal. In this episode, we’ll learn how Skomal’s research is revealing how these evolutionary survivors endure despite astonishing obstacles.
Greenland Shark: ExtrasAudio ExtraListen to Greg’s first EOL podcast about great white sharks. VideoWatch a video of a Greenland Shark from the Greenland Shark and Elasmobranch Education and Research Group (GEERG). Facts
The Greenland shark favors ringed seals (Pusa hispida), but has a wide diet that includes a wide variety of fish, dolphins, skates and other sharks, sea birds, sea urchins, crabs, and jellyfish. Carrion is also on the menu—the remains of drowned horses and reindeer have also been recovered from the stomachs of dead sharks. The copepod—a tiny crustacean—bores into the shark’s eye and leaves it almost blind. But the parasitic infection also lends the shark’s eyes an eerie, bioluminescent glow that seems to attract small prey. Since both copepod and shark benefit from this relationship, it’s called mutualism. The Inuktitut people of the Canadian Arctic call the Greenland shark the ekalugssuak. The flesh of the shark is high in neurotoxins—despite this, the Inuktitut consider the treated flesh a delicacy for for both man and beast. But if the powerful toxins aren’t removed the shark meat can leave sled dogs stumbling “drunk” and unable to stay on their feet. Citizen Science connection:Have you seen a shark near where you live?
