June 5, 2014 – Pledge Drive With Old Clips

Monday, 9 June 2014

On this special pledge drive show, PNM takes its new time machine for a spin to several shows in the past. First, we hear the opening intro of a pledge drive show from March 6, 1997 with PNM founder Kris Wedding. However, the time machine busted a gear or two, and we returned to today’s time, where Bill Scanlon and Dennis Shaffer continued highlighting the achievements of PNM to you, our listening audience, to get you to support us with a small donation. All of a sudden, the time machine kicked in again, and we were transported to the Great Dane Pub on Oct. 15, 1998. We did a challenging ‘live’ remote broadcast with several head beermeisters to talk about …. more »

ROM-BirdGallery-PassengerPigeon

This month is the 100th anniversary of the extinction of the Passenger pigeon, a very shameful anniversary for a bird that once numbered as many as 5 billion. The last one died in captivity at the Cincinnati Zoo. Extinctions of species are not uncommon when the delicate balance of nature occasionally veers off-course. Tonight, our very special guest, Stanley Temple, discusses the causes, potential future threats, and possible animal traits needed to weather these threats. Stan is the Beers-Bascom Professor Emeritus in Conservation at UW–Madison, and Senior Fellow at the Aldo Leopold Foundation. Human impacts have been the most devastating. In just a 50 year time span, humans hunted the Passenger pigeon into extinction. Stan mentions the number …. more »

March 20, 2014 – Dr. Harry Greene

Thursday, 20 March 2014

Tonight’s show is produced by Kaitlin Stack Whitney and engineered by Matthew Zmudka. Our guest tonight is Dr. Harry Greene of Cornell University. His research is on the behavior, ecology, evolution, and conservation biology of vertebrates and is especially interested in snakes. He talked about snakes, outreach, critical anthropomorphism, his path to a science career, and why natural history has all the cool questions (and genomics can help answer them) — among many other things! He’s an inspiration and was great fun to interview.   Check out his fantastic new book, Tracks and Shadows: Field Biology as Art. It’s in the UW library already and can be on your bookshelf ASAP. And his previous …. more »
