Hello all
Just point me in the right direction please (I hope to figure this out in
the next 36 hours for an assignment).
1) I have a dated tree from beast, and data with plant habit character
with 3 states (epiphyte, geophyte or other terrestrial). These habit
character states are I think correlated with dispersability. I would like
to test whether being in any of those states changes the rate of
diversification on the tree and whether it affects the number of geographic
regions occupied (continuous variable). Can you point me in the right
direction?
I do not have an estimate of the total number of species in each clade
though but have 80 taxa on the tree.
2) I also want to compare diversification rates between two separate dated
trees. Is there an accepted way to do that?
3) Also I have a matrix of taxa vs 9 regions with 0,1 or ? indicating
occupancy in each region, a few taxa occur in all regions, most in two,
some in one. Can I use this data and my time calibrated beast tree to
reconstruct ancestral areas in R?
Cheers
