Now that you’ve read and understood the Whitaker et al paper (link here) on Sulfolobus biogeography, please address the following for Tuesday 2/7:
1) How do their results relate to (or complicate) the Baas-Becking hypothesis (everything is everywhere, the environment selects)?
2) What else do you wish that they (or you) would do with this project, and why? What new questions do you have?
