Close the loop!


Humans are trashy... it's a natural fact. In the November 4th show, we learned about some human events that should probably have their own landfill! What are humans doing to deal with all the trash we generate? We could just throw it all away, or we could take three easy steps: Recycle, Reduce, Reuse... and close the loop! You can reduce and reuse by making smart decisions when it comes to purchasing. For example, avoid products with excessive packaging (reduce) and use cloth shopping bags (reuse).

Unfortunately for recycling, the success of this effort is partially determined by the facilities and services available to citizens. The city of Fayetteville, AR (home to KXUA) has had great success with its curbside recycling program, and we talked about some of the guidelines for what exactly can be placed in the green bins. The University of Arkansas campus has an active recycling program that is now sometimes extended to cover big events, such as football games (see Recycling with the Razorbacks).

As for the news, we heard about:
No sound quiz this week, but we heard from the likes of Modest Mouse, Sonic Youth, The Cramps, G. Love, Grandaddy, The Faint, Bloc Party, Trinity Roots, and more.

In nature, there are scarier things than ghosts!


In the October 28th show, we learned about bark and wood boring insects such as the European Elm Bark Beetle (Scolytus multistriatus), which is nonnative to the United States. This beetle is a vector for Dutch Elm Disease (DED), caused by a fungus which is transported via the water carrying vessels (i.e. xylem) of elm trees. In response, the tree plugs up its own xylem, thus stopping the movement of the fungus, but unfortunately also blocking movement of water and nutrients. An infected tree eventually loses its leaves prematurely and experiences branch dieback. Elms are commonly planted in urban areas because of their beautiful shape, so the effects of DED are quite visible. Treatment only prolongs the life of the tree at best, so research is currently underway to develop DED-resistant elms.

There are many stories of invasive insects in the U.S. that are changing our forests. For more information on such insects, visit the Forest Pests website. One thing you can do to help prevent the spread of damaging insects, particularly those that bore into wood, is to only burn firewood in areas where it originated, i.e. don't move firewood.

We also learned about the history of pumpkin carving and heard about some recent tidbits from nature:
For the sound quiz, we heard from some traditionally scary beasts such as vampire bats, screech owls, ravens, wolves, and mountain lions. Music featured included David Bowie, Aphex Twin, Mogwai, Blur, Starlight Mints, Devendra Banhart, Liz Phair, Yo La Tengo, and more!

Our pals, the pigments


On the October 21st show, we learned about why leaves change color during the fall in a temperate deciduous forest. Leaves are important sites of photosynthesis during the spring and summer months. The light-absorbing pigment, chlorophyll, gives leaves their green color. Deciduous trees lose their leaves in the winter in part because there is less water available for photosynthesis during the winter because of freezing temperatures. As the leaves senesce, the green pigment cholorphyll is broken down for its nitrogen, thus revealing accessory pigments such as carotenoids (oranges and yellows). Red is also often revealed, although these pigments (i.e. anthocyanins) are thought by some to be produced during the chlorophyll breakdown in order to protect tissues against the harmful rays of the sun - just like sunscreen!  It has also been proposed that red colors may help make plants less susceptible to attack by insects.

As for the news...

For the animal sound quiz, we heard from some bird species that spend their winters in the southeast United States, including the Yellow-rumped Warbler, Ruby-crowned Kinglet (pictured right), Yellow-bellied Sapsucker, Dark-eyed Junco, and White-throated Sparrow.

Music featured included The Twilight Sad, Azure Ray, Vivaldi, Olivia Tremor Control, Can, Radiohead, Joan Baez, Talking Heads and more.

Animal Bands

On the September 30th show, I featured bands that love the Kingdom Animalia so much that they decided to make animals their namesake. We heard from the likes of Deerhunter, Grizzly Bear, Cat Stevens, Fruit Bats, Cat Power, Neil Young and Crazy Horse, Bonobo, Deerhoof, The Mountain Goats, and The Toadies. Some of you may be thinking... hmmm... I wonder why that list is so disproportionately Class Mammalia! Well, so did I. Perhaps in future shows I will do a catalog search to come up with some bands whose names reflect Class Insecta or Aves... or maybe Subphylum Chelicerata? You can be assured that I will be doing more shows in which I focus on the music because I had a blast playing these tunes. Hope you enjoy them!

As for the news, we learned that:
It was an unconventional show, but a lot of fun. Check out the animal bands!

UPDATE: The following week, I did another animal bands show because I had so much fun with this one. Click here for the October 7th podcast.

Turn down that racket!


Inspiration for the September 23rd show came from the noise of the motorcycles that roared into Fayetteville for Bikes, Blues, and Barbecue - an annual motorcycle rally in Northwest Arkansas.  I featured stories about noise pollution and its effects on wildlife... particularly that associated with roads.  But it's not just automobile traffic that messes with wildlife... sonar used by seafaring vessels has been shown to wreak havoc on the navigation and health of marine mammals such as dolphins and whales.

Some interesting things were in the news...


Artists featured included: Mariee Sioux, Cake, The Pixies, Sufjan Stevens, Beck, Mylo, Islands, Ted Leo, Brian Eno, Grand National, The Mountain Goats, and America.

Most frequently quoted b.s. animal facts

Truth or fiction? Unfortunately this question does not oft enter the mind of a person when blurting out some of the most frequently quoted bullsh*t animal facts. On the September 9th show, we ran through a list of these erroneous ideas as seen on cracked.com. They included the mass suicide of lemmings, bees that fly in the face of the laws aerodynamics, the old ostrich with its head in the sand bit, and more.


As for the news in nature, we covered:No sound quiz this week :( Artists featured included: Rilo Kiley, The Faint, David Bowie, Eddie Vedder, Wire, Echo and the Bunnymen, Ryan Adams, Tripping Daisy, Deerhoof, Blackalicious, Calexico, and Billie Holiday.

F-I-R-E-I-N-C-A-L-I

Blaze like the fires in California. Blaze like a... fire.. fire.. fire. Just like The Cure is sweeping through my brain right now, so the wildfires swept through California at the end of the summer. In the September 2nd show, we talked all about wildfire and its effects on wildlife. The chaparral ecosystem of California is particularly susceptible to out of control fires because of the hot dry conditions of late summer. So often the media focuses on the property damage caused by these wildfires. What about the turtle that cannot outrun it? Or the bird whose nest goes up in flames? Sometimes even larger animals such as deer cannot out run it, as seen in shocking photos from this video. We learned about other critters affected by fire such as salamanders and shrews from a USGS podcast.

As for the news in nature, we heard about:No sound quiz again :( Darn wireless internet at the station is being finicky!

Music featured included: The Cure (of course), The Decemberists, Voice of the Seven Woods, John Fahey, M. Ward, Starlight Mints, Arcade Fire, Franz Ferdinand, and Billy Bragg and Wilco.

Gone grabblin'!

Forget your pole... if you want to catch the biggest, meanest catfish out there... you gotta use your hand. In the August 26th show, we heard a Nature Stories podcast out of Mississippi in which Doc Harrington describes how best to grabble.

We also listened to a recorded version of The Auklet from 1977, a lampoon publication put out by the American Ornithologists Union at their annual meeting (bird dorkdom at its finest). It included such gems as "Women's Lib. and the search for Graduate Students" and "Patience in Mistnetting by George Junkie".

In the news, They Might Be Giants have come out with a new album all about science. We heard an interview they did for Nature Podcasts. Check out their website for more news.

For the news in nature, we learned about:
Alas, we ran out of time for the sound quiz... but we did hear from such artists as: Primus, The Books, Aphex Twin, Brian Eno, Blockhead, TV on the Radio, Al Green, Nat King Cole, Josh Rouse, Ratatat, The Beatles, and the Pixies. Lots of music this week!

Pygmy Marmosets Grooming at the Philly Zoo


Here's a video of pygmy marmosets grooming one another at the Philadelphia Zoo. These are the smallest of the monkeys - weighing in at around 4.5 oz. They live in the rainforests of South America. An interesting things about these guys is that they are gummivores, meaning that they gouge the bark of trees with their elongated lower incisors to release sap or gum, which they then lap up. I was SO excited to see them close up because you could actually see their miniature underbites. For more on these little cuties, click here.

I just had to include the picture below to show how tiny their offspring are. These marmosets reproduce by twinning, meaning they have two offspring at a time. The young cling to their family members as the troop moves through the canopy in search of food.
