  • Empirical data sets used are Aphaniusiberus (killifish),Drosophila melanogaster, Lutra lutra (otter), and Gambusia affinis (mosquito fish).True Ne was estimated with pedigrees for Drosophila populations (England 1998). For mosquito fish populations, true Ne was estimated to be the number of adult founders (see methods; Spencer et al. 2000). S, sample size (or S0; S1 when sizes of the two temporal samples are different); T, number of generations between samples; L, number of microsatellite loci used.
