Smoke Chasers, Colorado Apples, Pikas. June 21, 2019, Part 2
06.21.2019 - By Science Friday
When wildfires rage in the West, Colorado State University atmospheric scientist Emily Fischer hops into a plane, and flies straight into the smoke. The plane is a flying chemistry lab, studded with instruments, and Fischer’s goal is to uncover the chemical reactions happening in smoke plumes, to determine how wildfire smoke may affect ecosystems and human health.
Pikas—those cute little animals that look like rodents but are actually more closely related to rabbits—used to roam high mountain habitats across the West. But global warming is pushing temperatures up in their high mountain habitats, and pikas are now confined to a few areas. And thanks to those warmer temperatures, which are threatening the pikas’ way of life, they may be in danger of disappearing—potentially as early as the end of the century. In this segment, recorded as part of Science Friday’s live show at the Chautauqua Auditorium in Boulder, Colorado, Ira speaks with Chris Ray, a population biologist at the University of Colorado in Boulder. Ray is tagging and tracking the pikas to investigate how closely their fate is tied to climate change—and whether there’s a way to save them before it’s too late.
In the late 1800, Colorado was one of the top apple growing states, but the industry was wiped out by drought and the creation of the red delicious apple in Washington state. But even today, apple trees can still be found throughout the area. Plant ecologist Katharine Suding created the Boulder Apple Tree Project to map out the historic orchards. She talks about Boulder’s historic orchards, some of the heirloom varieties like the Surprise and Arkansas Black, and a surprising connection to a hit Hollywood franchise. Plus, cider maker Daniel Haykin talks about how he uses the information from the Boulder Apple Tree Project combined with sugar, yeast and apples to make the bubbly beverage.
