Hi Jonathan.
The thing to do in this case is to estimate K with within-species
variability. This is described in Ives et al. (2007; Syst. Biol.) and
implemented in the phytools function phylosig. This will give an
unbiased estimate of K. (K estimated when within-species variability is

calculating the Blomberg K statistic in studies where there is more than one
data point for some species, by using a tree that includes zero-branch lengths
for those multiple studies. This seems ideal for our data, which h
