[Taxacom] Why I do this, and Why you should too -- The End

I am certainly curious about your experience and evidently Croizat did not lay out biogeography in a way that suited you. But one need not rely solely on Croizat's work. There was a book in 1999 that gave a fairly straightforward overview and outlined methodology with more detailed outlines cited in the literature. It also gave a glossary of terms. There are also some pretty comprehensive analyses published by Heads that illustrate the correlation between biogeography and tectonics.

Perhaps that is still not to your liking, and that's ok. 

I would be interested to see your draft contribution.
