Ashes and Adaptations

Science EN ↓ 5 episodes

"Ashes and Adaptations" is a five-episode mini-series discussing plant adaptations shaped by fire. The goal of the project was to create an overview of fire as an evolutionary force and explain how climate change is harmful to fire-adapted ecosystems. From trees with flammable oils to cones waiting to open until after a fire, this series discusses a variety of interesting ways plants have evolved with fire. Tune in to learn more!

From Soil to Canopy: A Discussion with Jamie Woolet and Sarah Hettema on Fire Ecology 30.11.2025 49:21

Welcome to a very special final episode of Ashes and Adaptations . To wrap up this mini-series, we will be discussing fire ecology with Jamie Woolet and Sarah Hettema. Jamie is a PhD candidate in the Department of Forest and Rangeland Stewardship at Colorado State University. Her research spans from the impact of wildfires on soil composition to how changing fire regimes affect avian communities....

The Phoenix Tree 30.11.2025 9:04

The eucalyptus is an iconic species across Australia. Join us as we explore what makes them so unique in fire ecology. In this episode of Ashes and Adaptations, we'll be exploring epicormic budding, flammability, and serotiny in the eucalyptus tree. Sources: Nolan, R. H., Bowman, D. M., Clarke, H., Haynes, K., Ooi, M. K., Price, O. F., ... & Bradstock, R. A. (2021). What do the Australian blac...

The Waiting Game: The Science of Serotiny 30.11.2025 9:36

Some species don't simply survive fire, they depend on it. In the third episode of Ashes and Adaptations , we will be discussing serotiny. This remarkable fire adaptation uses heat to trigger seed release. We'll explain what serotiny is, how it works, and why it is beneficial. Sources: Parchman, T. L., Gompert, Z., Mudge, J., Schilkey, F. D., Benkman, C. W., & Buerkle, C. A. (2012). Genome‐wid...

Layers of Surivival: The Power of Thick Bark 19.11.2025 10:13

In this episode of Ashes and Adaptations , we're discussing one of the most unassuming yet powerful fire-adapted traits: thick bark. Some trees are built with a natural armor that can protect them from the high temperatures caused by wildfires. We'll explore how fire shapes ecosystems, the science behind bark thickness, variation among species, and limitations regarding thick bark as an adaptation...

Overview of Evolution 19.11.2025 14:03

Welcome to Ashes and Adaptations ! This mini-series will be diving into various plant adaptations that have evolved in response to fire. This first episode explores evolution as a process, how adaptations arise, and corrects common misconceptions. Sources: Adaptation . (n.d.).
