Hi Brian, Liam and Graham,
Thanks a lot for these three suggestions! I'm actually going to go ahead
and try all three approaches. Appreciate the help!
Cheers,
Eliot

Hello all,
I've read some past posts and tried to figure this one out myself. It
appears that the short answer is if there are not some extinct lineages in
the tree with known trait values, it's difficult to do.
I have a data set of the current climatic niches of a continental radiation
of taxa.
We have a method in R, TreEvo, that can allow you to do things like have a
model where the optimum shifts through time according to some factor (like
external data on climate) or where there are constraints that change
through time: it's up on R-forge, and you can install the package, but it
If you want to do a Bayesian reconstruction for continuous traits with a
strong prior on the root - as Brian suggests - you can do this in the
phytools function anc.Bayes. The prior means variances need to be
provided in anc.Bayes(...,control=list(pr.var,pr.mean)). Unfortunately,
you need to
Hi Eliot and others,
You can also use the code contained in the fitContinuousMCMC package
