Estimates of the historical effective population size (Ne) obtained by the software GONE for a population with N = 1000 individuals which continuously receives migrants from a larger source population (Ns = 10,000) at a rate m per generation. The recipient population was either a kept at a constant population size, b subjected to a recent decline in size, c subjected to a recent population bottleneck and recovery, or d subjected to a recent expansion. The black dotted line shows the expected Ne from the variance of the progeny number (Exp NeVk) of the recipient population
