Selected Podcasts

earthworms

Earthworms are invading our forests

Podcast

In the northeastern U.S., all earthworms are non-native. And they are damaging our forest habitats.

unpaved road

The dirty truth about unpaved roads

Podcast

In rural areas, unpaved roads hold a certain charm. They restrict the volume and speed of traffic and, compared to their paved counterparts, are less expensive to build. But are they a greener alternative?

cardinal

Eavesdropping on your neighbors? Even the birds do it

Podcast

Most of us use the sounds around our homes to take measure of our neighborhood—it's all part of the information we process about our surroundings.

Why you should brake for possums

Podcast

The next time you see a possum playing dead on the road, try your best to avoid hitting it. Because it turns out that possums are allies in the fight against Lyme disease.

Are fish made of maple leaves?

Podcast

Most of us learned about the aquatic food web in high school. Using a sealed aquarium, teachers explained that plants form the base of the web, with the organic carbon they create supporting aquatic life—from invertebrates to sport fish.

fog

We all know about rain forests. Now we are learning about fog forests

Podcast

There's a desert in north-central Chile that receives less than six inches of rain a year. Right in the middle of it is a lush mountain forest that is dense with trees, bromeliads, ferns, and mosses.

Science, art, and music-all in the same room

Podcast

The Cary Institute of Ecosystem Studies is a scientific research and education organization. Sixteen Ph.D. scientists explore pressing environmental problems including acid rain, forest health, the ecology of Lyme disease, and pharmaceuticals in our waterways.

pearly mussel

Why should we care about freshwater mussels?

Podcast

There were once three hundred species of mussels in the United States. They supplied food to Native Americans and people harvested them for pearls and for mother-of-pearl to make buttons. Now, hardly anyone eats freshwater mussels and buttons are mostly made of plastic.

baltimore

Cities as ecosystems?

Podcast

Ecologists define an ecosystem as a unit of the landscape—a forest, a lake, or a river.  Often, they are interested in the movement of materials through that area.  Rain may deposit nitrogen in a forest, while a stream may carry nitrogen away from the forest and into a river.

acorns

Where did all the acorns go?

Podcast

For many years, oaks in the Northeast were prolific acorn producers. The 2010 crop was record-breaking—many will recall getting hit with acorn rain or slipping on acorns underfoot. Last fall, however, acorns were scarce.

Let's not put the last log on the fire

Podcast

In an attempt to wean the nation from coal—an unhealthy source of energy that drives global warming, several policy groups have suggested switching to wood. Existing coal-fired power plants could be converted to burn wood with relatively little cost and expense. And trees have the benefit of being a renewable resource.

Rethinking wild boars

Podcast

Wild boars are a problem in more than twenty states. These invasive animals are prolific breeders with voracious appetites. They cause tremendous damage to crops and native plant communities and they spread diseases, such as pseudorabies, from feral hogs to domestic livestock. 

All the salt we put on our roads in the winter has to go somewhere

Podcast

Across the Northeastern US, over 10 million tons of sodium chloride is applied to roadways annually. We also rely on salt to prevent falls on walkways and driveways. While useful for stabilizing slippery surfaces, salt use comes at a cost.

Hard or soft? When engineering shorelines, it makes a big difference

Podcast

Most of us have experienced a river shoreline— from a park, a train, or a boat. When we see where the water meets the land, how many of us have considered how modified shorelines influence river health?

Here's the fish, and here are the fish on drugs

Podcast

We are a nation of pill poppers. From statins to lower cholesterol to antidepressants to lift our mood, more than half of Americans are currently taking a prescription drug. Some twenty percent of us are taking three different prescriptions daily.
