ESU = Evolutionarily Significant Unit; N_e = effective population size per generation; N_T = total number of spawners per generation; N_eH= an estimator of N_e based on the harmonic mean of the number of spawners per year; the ‘~’ indicates a harmonic mean across generations. ^aThis group includes two closely related ESUs.
