Ep. 27 - Spring Ephemerals: Skunk Cabbage

It's not a skunk... and it's not a cabbage... This month, Steve and Bill discuss Skunk Cabbage. The guys go over the spathe, spadix, contractile roots, and thermogenesis, among other things. We also pose maybe too many questions to our audience:

1. Is Skunk Cabbage a clonal species?
2. Can Skunk Cabbage have multiple inflorescences? 
3. Do warblers nest in Skunk Cabbage spathes? 
4. Does Skunk Cabbage heat up to to promote cross pollination? 

Enjoy (and help us answer these questions)!

POST PRODUCATION NOTE:
The mic DID NOT pick up the brown creeper song. Steve had to edit that in during post production. The moment was real, but the audio of the song was enhanced for your enjoyment. 

Mistakes:
Steve suggests that species maps can be created from aerial photographs. This is almost certainly wrong... he was thinking of identifying wetlands, not producing specific species range maps, from aerial photographs. Some wires got crossed in his brain.
