The Discover Life in America Podcast brings you into natural wonders of GSMNP through conversations with the experts. We interview park biologists, resource managers and other researchers to get the latest on all things related to science in the Smokies and the All Taxa Biodiversity Inventory. Jaimie Matzko is the host and Director of Communications and Outreach with DLiA. We are the science partner of GSMNP and nonprofit organization, founded 27 years ago to find and record every species in the park. Thanks for listening!
Episode 3: Sequencing the Smokies: DNA Barcoding with Paul Super, Research Coordinator at GSMNP
In this episode of Discover Life in America, host Jamie Matzko interviews Paul Super, a research coordinator at Great Smoky Mountains National Park, about the innovative use of DNA barcoding in biodiversity research. They discuss the historical context of research in the Smokies, the significance of environmental DNA, and the challenges of defining species. The conversation highlights the importance of protecting biodiversity and the advancements in DNA barcoding technology that aid in species identification. They also touch on the exploration of understudied taxa in the park, emphasizing the ongoing discoveries in this rich ecosystem. (Recorded May 16, 2023)

Episode 2: Interview with Keith Langdon, the “Father of the Smokies ATBI”
In closing our 25th Anniversary year of the All Taxa Biodiversity Inventory (ATBI), Discover Life in America Podcast host, Jaimie Matzko, talks to Keith Langdon, retired GSMNP Supervisory Biologist, also known as the “Father of the ATBI” to find out what it like to start such an ambitious project.
The Smokies ATBI, a project that Discover Life in America manages in partnership with GSMNP, seeks to catalog the estimated 60,000-80,000 species of living organisms in Great Smoky Mountains National Park. A brainchild of renowned ecologist Dan Janzen, the first ATBI was supposed to take place in the rainforests of northwest Costa Rica. Due to bureaucratic difficulties, however, the location was changed to the Great Smoky Mountains National Park.
The idea behind an All Taxa Biodiversity Inventory (ATBI) is simple. If we want to be good stewards of our environment and keep the world around us healthy and vibrant, we need to understand the web of biodiversity. The information we need—how many species live in an environment, what jobs these species do and how they interact with each other—is largely unknown.
