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.
