I worked out an estimate of the merger rate for LRGs from Morad's correlation function result. It is one LRG-like merger for every LRG every 30 Gyr at the mean redshift of the LRG sample, z~1/3.
I commented on the appearances of the top 30 or so K+A-nuclei galaxies in Blanton's lowz sample. Many of them have evidence of recent (last few dynamical times) merger activity. Many do not, of course, but I think it will be much more common than in control samples (to-do).
