Hello Oliver, I completely agree with Julien. I’d add however that when running a PGLS with different branch length transformations you are in fact comparing among different models of trait evolution, which make different assumptions about how traits change along the phylogeny. Thus, I would

Hi Oliver, Your model comparison tells you that the "lambda" is better than "kappa", and hence that it should provides a better phylogenetic structure for the corresponding regression test. Making a model comparison to choose the structure is probably best practice, but it also depends on the
