Summary

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.

0:00.0	Hello everyone and welcome to the Indefensive Plants podcast
0:03.8	of Indefensive Plants.
0:05.2	What's up? This is your host Matt. Welcome to the show.
0:07.3	How is everyone doing this week?
0:08.9	I'd be doing so great if you considered supporting Indefensive Plants as a patron over at patreon.com
0:14.5	slash Indefensive Plants. It is one of the best ways to make sure this show can keep coming out each
0:19.2	and every week because I could not be doing Indefensive Plants without support and I thank each and every one of my patrons that pitches in every month and they're getting great kickbacks in the process such as access to bonus episodes.
0:31.0	But that's enough of that. Today is a really interesting conversation
0:34.8	with someone that's stumbled into a fascinating topic that involves milk weeds
0:39.8	and milkweed butterflies. I'm not just talking about the
0:42.8	sclepious in the monarch butterfly as you're going to hear it's a much bigger
0:46.0	picture that spans the globe and it all has to do with chemical ecology and
0:50.2	phylogeny and how evolutionary history has played out to produce some really fascinating plant insect
0:56.0	interactions.
0:57.6	Joining us to talk about this is Dr. Tani Lipschulz and she is so deeply passionate
1:02.3	about this system and has uncovered so many amazing things.
1:04.8	I don't want to steal any of her thunder, so how about we just jump right into it?
1:08.0	Without further ado, here's my conversation with Dr. Tiney Live Schultz. I to the podcast. I am so excited to pick your brain today, but first let's start off with an introduction.
1:34.2	Tell everyone a little bit about who you are and what it is you do.
1:37.8	All right.
1:38.8	Well, I'm Tanya Lipscholts.
1:41.8	I am an associate professor at Drexel University and I'm also
