LBD and DBD indicate ligand and DNA binding domains, respectively. OInline graphic, OInline graphic, OInline graphic and OInline graphic are the O. mykiss ERInline graphic, ERInline graphic, ERInline graphic and ERInline graphic genes, respectively. SInline graphic indicates all of the salmonid ERInline graphic genes. Inline graphic and Inline graphic indicate ERInline graphic and ERInline graphic from all fish, respectively. Inline graphic is the number of parameters in the model, Inline graphic 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.
