Ep. 479 - Insights into Nightshade Defenses

Plants cannot run away from the herbivores that eat them, therefore plants have evolved numerous strategies to defend themselves from being consumed. Plant defenses are as varied as the plant kingdom and the ways in which they operate will blow your mind. We are joined by Dr. Rupesh Kariyat who studies plant defenses in a variety of nightshade relatives including the tomato. Tune in as we discuss how these plants defend against herbivory and learn how human activities such as mowing may have unintended consequences for some plant species.

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. This episode was produced in part by Robert, Thomas, Valerie, Joan, Mohsin Kazmi Photography, Cathy, Simon, Nick, Paul, Charis, EJ, Laura, Sung, NOK, Stephen, Heidi, Kristin, Luke, Sea, Shannon, Thomas, Will, Jamie, Waverly, Brent, Tanner, Rick, Kazys, Dorothy, Katherine, 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, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.

Ep. 372 - Cyanogenic Plants

Cyanide is one of the most potent toxins on our planet and a bewildering variety of plants put in the effort to produce it. Join me and Dr. Scott Zona as we explore the world of botanical cyanogenesis and learn what kinds of plants produce cyanide, the mechanisms of storing and releasing this toxin, and why they go through all the effort. This episode was produced in part by 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. 155 - Understanding Floral Chemistry

For Dr. Rob Raguso, the phrase "stop and smell the roses" takes on a whole new meaning. Dr. Raguso studies the intricate world of floral chemistry. You are undoubtedly familiar with some of the wonderful odors flowers produce but such tantalizing smells are only the beginning. The world of floral chemistry is quite remarkable and the function of the myriad substances they produce go much deeper than simply pollination. This conversation will put a whole new spin on your appreciation of flowering plants. This episode was produced in part by Letícia, Ron, Tim, Carl, Lisa, Susanna, Homestead Brooklyn, Daniella, Brodie, Kevin, Katherina, Sami & Sven, Sophia, Plant by Design, Mark, Rens, Mountain Misery Farms, Bendix, Irene, Holly, Clifton, Shane, Caitlin, Rosanna, Mary Jane, Manuel, Jennifer, Sara, and Margie.

Ep. 148 - Cecropia Trees, Ant Bodyguards, and Collective Personality

Plants, being sessile organisms, must go to great lengths to protect themselves from herbivores. Sometimes this takes the form of spines or thorns, sometimes its nasty chemicals, and sometimes it means recruiting ants as bodyguards. Peter Marting is my guest today and he studies how one group of tropical trees in the genus Cecropia recruits and houses ants and how the interaction between these two different organisms influences the collective personality of the ant colonies. This episode was produced in part by Tim, Lisa, Susanna, Homestead Brooklyn, Daniella, Brodie, Kevin, Katherina, Sami & Sven, Sophia, Plant by Design, Mark, Rens, Mountain Misery Farms, Bendix, Irene, Holly, Clifton, Shane, Caitlin, Rosanna, Mary Jane, Manuel, Jennifer, Sara, Sienna & Garth, Troy, and Margie.
