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. 320 - The Prehistoric Path to Flowering Plants

Resolving the origins of flowering plants requires an understanding of how their morphology came to be. After all, despite their rapid appearance in the fossil record, flowering plants did not evolve over night. There had to be transitional phases between what we recognize as a gymnosperm and what we recognize as an angiosperm and that is what this episode is all about. Sir Peter Crane of the Oak Spring Garden Foundation joins us to discuss some intriguing fossils that he and his colleagues hypothesize represent important steps in the early days of flowering plant evolution. This episode was produced in part by 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. 304 - Proteas: Protecting These Botanical Shape-Shifters

For those with even passing familiarity, the proteas represent something akin to botanical royalty. This family of plants exhibits a bewildering array of forms, lifestyles, and habitat preferences, which is why they were named in honor of the shape-shifting Greek god Proteus. Whereas Proteus was confined to the water, the proteas can be found growing terrestrially throughout the Southern Hemisphere where they face myriad environmental threats. Indeed, the most recent IUCN Red List Assessment has found that roughly 45% of proteas are threatened with extinction. Our guest for this episode wants to do everything they can to help reverse at least some of these alarming trends. Robbie Blackhall-Miles has turned a passion for horticulture and a lifelong obsession with conservation into something amazing: a home-grown botanical garden dedicated to saving some of Earth's strangest and overlooked plant species. Tune in and find out how a tiny garden tucked behind a little cottage in the mountains of Wales has become a major force for plant conservation efforts.

Ep. 253 - Earth's First Forests

The Devonian Period was for plants what the Cambrian Period was for animals. Land plants really started to experiment with new forms of growth some 380 million years ago which led to the establishment of the first forests on Earth. My guest today is Dr. Chris Berry who was part of the team that recently discovered the oldest fossil evidence of forests. As you are going to hear, these forests were very different from the ones we know and love today. This episode was produced in part by Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donna, 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. 202 - Getting to the Root of Roots

There is no denying that roots are one of the most important organs on a plant. However, unless its an epiphyte, root activity takes place underground, largely out of site and out of mind. This has not stopped my guest today from trying to understand the origin and evolution of these amazing structures. Joining us from Magdalen College in the UK is plant evolutionary biologist Dr. Sandy Hetherington whose work spans hundreds of millions of years of root history. Join us as we explore the early days of root evolution and learn how things like fungal symbionts and a lack of organic matter set the course for root evolution. As you will hear, this work also relies heavily on museum and herbarium collections, underscoring the importance of preserving these important data goldmines. This episode was produced in part by Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 188 - On the Origin of Flowering Plants

Despite their dominance on the landscape today, figuring out exactly when flowering plants got their start has been a challenge facing paleobotanists since Darwin's time. This so-called "abominable mystery" is nonetheless fascinating to study and that is exactly what our guest today focuses on. Joining us is Dr. Nan Crystal Arens from Hobart and William Smith Colleges. Her work on angiosperms of the early Cretaceous has given us insights into the evolutionary pressures that may have led to the evolution of flowering plants as well as how these early angiosperms made their living in a landscape already vegetated by a preponderance of gymnosperms. If you care at all about the history of plants on this planet, this is one episode you do not want to miss!

Ep. 136 - Uncovering Antarctica's Forested Past

It may be hard to believe but Antarctica has a green past. Throughout its history, our southern polar continent has been the home to a variety of now-extinct biomes and my guest today is responsible for uncovering the oldest of these remains. Dr. Erik Gulbranson is part paleoecologist and part paleoclimatologist and what he and his collaborators are learning from these fossilized ecosystems not only helps us understand how life responded to climate change in the past, but also how it may respond in the future. This is one you don't want to miss! This episode was produced in part by Brian, Mark, Rens, Bendix, Irene, Holly, Clifton, Shane, Caitilin, Rosanna, Mary Jane, Manuel, Jennifer, Sara, Sienna & Garth, Troy, Margie, and Laura.
