Ep. 478 - Milkweed Defense De-Escalation

June 16, 2024

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. 408 - Prairie Up!

February 12, 2023

Do you want to bring native plants into your life in ways that will inspire others? Do you want to turn whatever space you have into habitat that fosters biodiversity? Diving into the world of ecological landscaping may seem daunting at first, but books like "Prairie Up" helps turn the learning curve in an exciting on-ramp. Join me and author Benjamin Vogt as we dive into the inspiration and philosophy behind this amazing and beautiful book. This episode was produced in part by Emily, Theo, Nichole, Paul, Karen, Randi, Caelan, Tom, Don, Susan, Corbin, Keena, Robin, Peter, Whitney, Kenned, Margaret, Daniel, Karen, David, Earl, Jocelyn, Gary, Krysta, Elizabeth, Southern California Carnivorous Plant Enthusiasts, Pattypollinators, Peter, Judson, Ella, Alex, Dan, Pamela, Peter, Andrea, Nathan, Karyn, Michelle, Jillian, Chellie, Linda, Laura, Miz Holly, Christie, Carlos, Paleo Fern, Levi, Sylvia, Lanny, Ben, Lily, Craig, Sarah, Lor, Monika, Brandon, Jeremy, Suzanne, Kristina, Christine, Silas, Michael, Aristia, Felicidad, Lauren, Danielle, Allie, Jeffrey, 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. 73- On Milkweeds and Monarchs: The Search for a Smoking Gun

September 11, 2016

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.

Episode 2 - Monarchs and the Subnivean Realm

January 18, 2015

Monarch butterflies (Danaus plexippus) are up for a potential listing on the Endangered Species List. Fellow botanical enthusiast Steve Fleck stops by for a discussion on the implications of such a listing followed by an introduction to life under the snow in the subnivean zone.
