Change in N_e was estimated using LinkNe for each model based on 1000 single-nucleotide polymorphism (SNP) loci and a sample size of 50 except where the change in N_e generated a population of <50 individuals (in which case all individuals were sampled). Change in N_e was detected when confidence intervals between estimates from the most distant past (14.3 generations) and those from the most recent past (1.01 generations) did not overlap.
