Hello,
I am wondering what comparative method(s) is appropriate for testing if
diversification rates are highest when two traits are present together,
rather than one alone? Specifically, if I have two binary traits, let's say
freshwater/marine and temperate/tropical, what is the best way to test
I'm not sure of any particular methods that do this, but one preliminary
approach that you could try is combining the two traits into a single trait
(00, 01, 10, and 11) which you could then analyze with any of the standard
methods. You could then look for whether any of the states have higher or

Hello,
Personally, I would advise you not to use a tree, for your 2 traits times 2
(+/-) makes 4 combinations, meaning a tree that is dichotomic cannot reveal
anything! Can you quantify your "diversification" without "rate"? How do you
obtain your "diversification rates"? If it is something
