Hi Christoph, Stacey,
This might be a problem for which a logistic regression
(http://en.wikipedia.org/wiki/Logistic_regression) would be
appropriate. If so, I encourage you to check out the following article,
which I enjoyed:
Ives, A. R., and T. Garland Jr. 2009. Phylogenetic logistic regression
for binary dependent variables. Systematic Biology (Advance Access).
Others on this list-serve might also be well suited to comment on this
paper & method.
