Ep. 216 - Dying Bees, Wasp Venom, and other Strange Floral Scents

Today we focus on a group of plants whose floral morphology and chemistry are sure to blow your mind. Join Dr. Anne Heiduk and me as we discuss the bizarre chemical ecology of Ceropegia. Members of this genus have gained a lot of popularity as houseplants in recent years but we still know very little about how they behave in the wild. From dying bees and wasp venom, to rotting meat and possibly even fly sex pheromones, there seems to be no end to how much trickery Ceropegia have evolved to dupe flies into pollinating their flowers. What's more, this research goes far beyond pollination ecology. As you will hear, Dr. Heiduk and her colleagues are unlocking new insights into chemistry, physiology, neurobiology, entomology, and even mycology!

Ep. 176 - On Pawpaw and Floral Mimicry

The world of floral mimicry really busts open traditional views on pollination. This spectrum of strategies involves things like poop and carrion mimicry, sexual mimicry, and possibly even fruit mimicry. That is where today's guest comes in. Joining us is Dr. Kate Goodrich, a chemical ecologist from Widener University who studies floral chemistry in the context of mimicry. Her system of interest involves pawpaw and other Asimina species, whose flowers take on strange fermented odors. Join us for a fascinating dive into the world of what makes a flower a good mimic. This episode was produced in part by Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Lisa, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 158 - Pollination of Neotropical Aroids: A New Look At Some Old Friends

Join University of Vienna PhD student Florian Etl for an in depth look at a pollination system involving some of our most beloved houseplants. Florian focuses on genera like Philodendron, Anthurium, Dieffenbachia, and Spathiphyllum to shine light on how the plants manage to reproduce in the hyper diverse rainforests of Costa Rica. This is not easy work by any means but Florian and his colleagues are finding out new and wonderful things about the natural world. This is one episode you do not want to miss. 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. 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.
