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

January 22, 2023

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. 325 - Toxic Soils & Drinking Water From Rocks

July 11, 2021

Everyone needs a bit of calcium in their diet, but too much of it can cause serious health issues. The same is true for plants. Growing in soils high in calcium is no walk in the park and yet, around the world, we see many plants that have adapted to soils made toxic by calcium sulfate. How they manage to adapt to such conditions is the main research interest of Dr. Sara Palacio. She focuses her work on the evolution and physiology of plants that grow in soils dominated by gypsum. Her work has her looking at everything from how plants use calcium sulfate to their advantage and the effects of herbivory on gypsum endemics to how some plants are able to get water directly from rocks!

Ep. 324 - Palms Through Deep Time

July 4, 2021

Palms (Arecaceae) are among the best known and easily recognizable groups of plants on Earth. Their diversity is staggering and they play important roles in the ecology of the habitats in which they grow. But how much do we know about their evolutionary history? What can a deep time perspective teach us about palm evolution. Joining us to talk about this is paleobotanist Dr. Kelly Matsunaga. Dr. Matsunaga uses the palm fossil record to investigate a variety of palm-related topics from the evolutionary origins of modern palm diversity to the origins of tropical rainforests. This episode was produced in part by Amanda, Tommy, Marcel, C Leigh, Karma, Shelby, Christopher, Alvin, Arek, Chellie, Dani, Paul, Dani, Tara, Elly, Colleen, Natalie, Nathan, Ario, Laura, Cari, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Azomonas, Ellie, University Greens, Joseph, Melody, Patricia, Matthew, Garrett, John, Ashley, Cathrine, Melvin, OrangeJulian, Porter, Jules, Griff, Joan, Megan, Marabeth, Les, Ali, Southside Plants, Keiko, Robert, Bryce, Wilma, Amanda, Helen, Mikey, Michelle, German, Joerg, Cathy, Tate, Steve, Kae, Carole, Mr. Keith Santner, Lynn, Aaron, Sara, Kenned, Brett, Jocelyn, Ethan, Sheryl, Runaway Goldfish, Ryan, Chris, Alana, Rachel, Joanna, Lori, Paul, Griff, Matthew, Bobby, Vaibhav, Steven, Joseph, Brandon, Liam, Hall, Jared, Brandon, Christina, Carly, Kazys, Stephen, Katherine, Mohsin Kazmi Takes Pictures, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.

Ep. 314 - The Silversword Alliance

April 25, 2021

In this episode, we take a deep dive into the wild world of the Hawaiian silversword alliance. This group of daisy relatives represents one of the most remarkable adaptive radiations on the planet and is comprised of three genera: Wilkesia, Argyroxiphium, and Dubautia. From tiny cushion plants to woody trees and vines, these unique plants have done amazing things on the Hawaiian Archipelago. Even more amazing is the fact that all of them can trace their origins back to a single seed of a daisy relative called a tarweed growing in California. Against all odds, that seed made it across the Pacific and the rest, as they say, is history. Joining us to talk about that history is Dr. Bruce Baldwin, a professor at UC Berkeley and curator of the Jepson Herbarium. Dr. Baldwin has spent his career trying to unravel the evolutionary mysteries of this group and has made some important insights into the processes of evolution along the way. This episode was produced in part by Chellie, Paul, Dani, Tara, Elly, Colleen, Natalie, Liam, Ario, Nathan, Laura, Cari, Laura, Kali, Margaret, Mary, Connor, 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. 300 - Reconstructing a Cretaceous Flora

January 17, 2021

Imagine being able to travel back 120 million years to the Early Cretaceous and scoop up handfuls of the forest floor. The amount you would discover in that material would be mind blowing and, amazingly, this is essentially what my guest gets to do. Dr. Fabiany Herrera is a paleobotanist based at the Chicago Botanic Garden who is currently helping reconstruct the flora of an ancient Mongolian swamp. Mongolia is well known for its dinosaur fossils, but what Dr. Herrera and his colleagues are uncovering is amazingly preserved evidence of the ecosystem that once support them. From resolving relationships among extant gymnosperms to describing new taxa, there seems to be no end to the information packed away in these amazing fossils. Join us as we catch a glimpse of an Early Cretaceous flora. This work was funded by the National Science Foundation.

Ep. 298 - Living the Gypsum Life: How Geology Can Drive Speciation

January 3, 2021

You may have heard of the mineral gypsum through its use in making plasters, chalks, and drywall, but are you aware of its influence on plant speciation? Indeed, soils heavy in gypsum present unique challenges to plant growth but that doesn't mean plants haven't been able to conquer such substrates. In this episode, I sit down to talk with Dr. Mike Moore about his research on how gypsum-based soils have resulted in remarkable evolutionary radiations on a global scale. Along the way we gain important insights into how soils can drive evolution and why some plant lineages may be more likely to adapt to gypsum than others.

Ep. 282 - The Rosid Radiation

September 13, 2020

When we think of biodiversity and evolution, the tropical regions of our planet are frequently touted as hotspots for speciation. Indeed, the tropics house more species than most other regions, however, that doesn't mean that temperate areas haven't contributed to the diversity of life on this planet. Recent work has revealed that one of the largest clades of flowering plants, the rosids, are evolving much faster in temperate areas than the tropics. Joining us to talk about this is Dr. Miao Sun, who along with a team of scientists, is uncovering surprising revelations about the evolution of this diverse plant lineage. Their work is opening so many new doors to understanding some of the most iconic plants on Earth. This podcast was produced in part by 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. 236 - Ferns & Lycophytes, Hybrids & Polyploids

October 27, 2019

Ferns and lycophytes are very special plants. Their origins date back hundreds of millions of years. Representatives of these two lineages can be found all over the globe and yet we know much less about them than we do flowering plants. My guest today is trying to change that. Joining us from the University of Florida is Dr. Weston Testo. Weston wants the world to know that ferns and lycophytes are not only incredible plants, they are also surprisingly diverse. What's more, a huge chunk of that diversity is the result of both genome duplication events and hybridization events between different species. The world of fern evolution is ripe for discovery and Dr. Testo and his colleagues are uncovering incredible information about these charismatic plants. Join us for a discussion about evolution and diversification of ferns and lycophytes.
