And don't forget that measurement error in the tip data will also cause
underestimation of phylogenetic signal, unless you use methods specifically
designed to allow for that!

A deep thought on this topic, from a mind run aground amidst grading papers.
While I am a big fan of using multiple trees, we should keep in mind
that phylogenetic uncertainty makes signal into a rather snaky
concept. By this, I mean that there could have only been one true

Hello R-sig-phylo community,
I am trying to measure the phylogenetic signal of functional traits with the
Blomberg’s K and Pagel’s λ methods. My problem is that I don’t have one
phylogenetic tree but 1000 (the trees were created by first combining different
molecular, morphologic and
