Ep. 478 - Milkweed Defense De-Escalation

Plant defense compounds are great for the plants that produce them as they can ward off herbivore attacks. But what happens when a group of specialists evolves a way to utilize said compounds? Such is the case for milkweeds (Apocynaceae) and milkweed butterflies (Danaina). A long evolutionary history together kicked off an evolutionary arms race driven by chemical ecology that is turning into a case of chemical de-escalation for many plants within this family. Join me and Dr. Tanya Livshultz as we explore the links between phylogeny, herbivory, and milkweed diversity.

Ep. 280 - At the Intersection of Conservation and Horticulture

In this episode we are joined by Conservation Horticulturist Emma Neigel of the Atlanta Botanical Garden to talk about the intersection of horticulture and conservation. When it comes to plant conservation, it isn't enough to just study why plants are rare, we must also learn what they need to grow and thrive. Being able to grown and propagate rare plants offers many species the hope of a brighter future. Join Emma and me as we discuss everything from growing rare milkweeds to finding new populations of endangered orchids in the wild and everything in between. This podcast was produced in part by 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. 270 - A Native Plant Based Life

This episode is all about celebrating native plants both in the wild and in the garden. We are joined by environmentalist, author, and garden designer Lyndon Penner to talk about his life-long obsession with Canada's amazing diversity of native plants. From the mountains to the prairies, Lyndon is a lover of all things botanical. He began growing plants at the tender age of 3 and designed his first perennial border at 9 and hasn't stopped since. Lyndon not only designs native plant gardens, he also writes about them and has authored numerous books centered around gardening in regions with short growing seasons. It is always a blast geeking out about native plants with people like Lyndon so join us for a fun discussion about the wonders of native plants. This episode is sponsored by The Great Courses Plus and was produced in part by 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. 223 - The Magnificence of Milkweeds

In this episode, we take a deep dive into the world of milkweeds. The genus Asclepias has been made famous due to the plight of the monarch butterfly, whose larvae feed on nothing else. Though we tend to focus our attention on only a handful of milkweeds, these plants are incredibly diverse and have a lot to teach us about ecology, evolution, and biogeography. Joining us to talk about this incredible group is the Milkweed Guy himself, Dr. Mark Fishbein. Dr. Fishbein and his colleagues are working hard on piecing together the history of Asclepias in North America. If you thought milkweeds were incredible plants before, this conversation will certainly amplify your appreciation for these incredible plants. This episode was produced in part by 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, 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. 145 - Obscure Apocynaceae Appreciation

There are far too many plants in this world that get little to no attention. Such is the case for a group of milkweed relatives in the genus Chthamalia. Luckily for these plants, a chance encounter by Dr. Angela McDonnell led to a wonderful world of discovery. From describing new species to understanding the evolution of this amazing group, Dr. McDonnell has opened our eyes to the wonders of the genus Chthamalia. Join us for a fun discussion about her love for plants and their evolution. The episode was produced in part by Lisa, Susanna, Homestead Brooklyn, Daniella, Brodie, Kevin, Katherina, Sami & Sven, Sophia, Plant by Design, Mark, Rens, Bendix, Irene, Holly, Clifton, Shane, Caitlin, Rosanna, Mary Jane, Manuel, Jennifer, Sara, Sienna & Garth, Troy, Margie, and Laura.

Ep. 73- On Milkweeds and Monarchs: The Search for a Smoking Gun

Monarchs have become the poster child for protecting, conserving, and restoring native flora. Over the last decade monarchs have witnessed massive declines in their numbers. This has led to a lot of speculation as to what might be causing such declines. It seems like a simple black and white issue, monarchs need milkweed and we have plowed over most of the milkweed on this continent. As straight forward as this may seem, students of ecology will note that nothing in nature is that simple. Monarch and milkweed conservation is a complex issue with a lot of causes and that is where people like Dr. Greg Spyreas come in. Using large scale datasets, Greg and his colleagues are painting a more nuanced picture of milkweed and monarch decline. It is an interesting story that you don't want to miss. This episode was produced in part by Gregory, Mark, and Bryan.
