Regarding question (1) here is a solution that I posted earlier:

All the best, Liam

Dear r-sig-phylo community,

I am analysing phylogenetic signal in univariate quantitative traits in 
insects. I use Blomberg's K (command phylosignal, library picante). Here I have 
two questions:

- how can I test whether K differs from the Brownian Motion Model?

- is it safe to assume phylogenetic overdispersion if the phylogenetic signal 
differs both from random and from the BM model?


Thanks a lot for your help!
