Ep. 202 - Getting to the Root of Roots
In Defense of Plants

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.

Ep. 189 - When Palms Grew in Wyoming

Ep. 189 - When Palms Grew in Wyoming
In Defense of Plants

Join Dr. Sarah Allen and me as we journey back in time to the Eocene. Earth was a very different planet some 49 million years ago. Though we may recognize some Eocene flora, the combination of various plant lineages would be enough to make your head spin. Earth was experiencing a warming period and the plants had responded accordingly. Tropical species like palms were thriving in places like Wyoming and giant relatives of the redwoods covered much of North America and Asia. What Dr. Allen and her colleagues are learning about Eocene plant communities is not only interesting in its own right, it is helping scientists understand how ecosystems may respond to climate change into the future. This episode was produced in part by Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, 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, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 188 - On the Origin of Flowering Plants

Ep. 188 - On the Origin of Flowering Plants
In Defense of 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! This episode was produced in part by Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, 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, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 184 - Fossilized Bryophytes: A Journey Back In Time

Ep. 184 - Fossilized Bryophytes: A Journey Back In Time
In Defense of Plants

The odds of any living material becoming fossilized are extremely rare, especially if that living thing is a moss, liverwort, or hornwort. It does happen, however, and my guest today is dedicating his career to studying and understanding what bryophyte fossils can tell us. Joining us is Alex Bippus, a PhD student at Oregon State and his work is absolutely fascinating. From climate change to evolution, there seems to be no end to the fun of studying bryophyte fossils. This episode was produced in part by Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, 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, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.
