eLife assessment
This is a valuable comparative study of local adaptation using gene-by-environment and gene-by-phenotype correlations. The analyses seemed still incomplete, as the biological take-home messages were obscured by the statistical approaches used, and it remains unclear how to best interpret the level of genome-wide convergence and in inversions. The repeatability of local adaptation across species, and the role of inversions in local adaptation, are questions of considerable empirical interest.
