Soundbite: Have you met FRED? The Fine Root Ecology Database — also known as FRED — is a collection of root trait data from research performed around the world. Roots play an important role in all ecosystems, but are often overlooked by computer models. The data in FRED can help computer modelers more accurately predict climate change scenarios. In this shorter installment of "The Sound of Science" podcast series, you'll hear from ORNL scientist and root aficionado Colleen Iversen, who leads the effort to collect data for FRED.
