LBD and DBD indicate ligand and DNA binding domains, respectively. O, O, O and O are the O. mykiss ER, ER, ER and ER genes, respectively. S indicates all of the salmonid ER genes. and indicate ER and ER from all fish, respectively. is the number of parameters in the model, is the log likelihood calculated by PAML, and AIC is the Akaike Information Criterion value [35]. Models labeled with an asterisk are the best fitting models based upon the AIC values.
