Ep. 405 - Early Land Plants & Earth's Ancient Climate

The earliest days of land plant evolution have long thought to have occurred in a hot house environment fueled by high CO2 levels. However, recent investigations suggest this may not have been the case and that small plants, not forests, had a massive role to play. Join me and Dr. Tais W Dahl as we travel back over 400 million years to the Devonian Period and discuss how small relatives of lycopods may have altered Earth's atmosphere to such a degree that the Devonian climate may have been more familiar than once hypothesized.

Ep. 400 - The Root of an Ancient Mass Extinction

We take plant roots for granted, but there was a time in Earth's history when roots had yet to evolve. As you are going to hear from Professor of Earth Sciences, Dr. Gabe Filippelli, when roots did evolve, they may have set in motion a mass extinction of oceanic proportions. Learn what he and his colleagues have discovered and what it can teach us about Earth's biosphere moving forward.

Ep. 303 - Lessons in Biogeography from Conifers

This episode occurs at the intersection of botany and geology, two inseparable components of the natural world. For Dr. David Charlet, what started with curiosity about a seemingly out of place population of conifers has developed into a life-long obsession with species distributions and deep time. Dr. Charlet specializes in the biogeographic history of the Great Basin and Mojave Desert with a special interest in conifers and has greatly advanced our knowledge of how geology and climate have shaped the flora of this region. This podcast was produced in part by Nathan, Jan, Jerome, Brian, Melody, Azomonas, Ellie, University Greens, Cynthia, John, Ashley, Peter, Cathrine, Melvin, OrangeJulian, Porter, Grif, Jules, Joan, Les, Marabeth, Ali, Margaret, Southside Plants, Robert, Keiko, Bryce, Brittany, Helen, Amanda, Mikey, Rhiannon, Michelle, Kate, German, Joerg, Alejandra, Cathy, Jordan, Judy, Steve, Kae, Carole, Mr. Keith Santner, Dana, Chloe, Aaron, Sara, Kenned, Vaibhav, Kendall, Christina, Brett, Jocelyn, Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donica, Chris, Shamora, Alana, Laura, Alice, Sarah, Rachel, Joanna, Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Liba, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 177 - Serpentine Specialists & Their Evolution

My guest today is Shelley Sianta, a PhD student at UC Santa Cruz, and she studies evolution in a group of plants that have specialized on serpentine soils. These may sound like sketchy conditions and indeed they are. Serpentine soils are high in toxic metals and low in precious nutrients. As such, the plants that live there have evolved a variety of coping mechanisms. Its these coping mechanisms that interest Shelley Sianta as they may be at the root of why we see such high rates of endemism on these toxic soils. Listen in for a fascinating exploration of plant evolution. This episode was produced in part by Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Lisa, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.
