Abstract

Letter to the editor: Here we refute Franklin et al. (2014) and clarify the basis of our recommendations (Frankham et al., 2014) on the 50/500 rules for effective population sizes (Ne). These thresholds, required to avoid inbreeding depression in the short-term and loss of evolutionary potential in perpetuity (Franklin, 1980), need to be increased to 100 and 1000, respectively, along with corresponding doubling of the IUCN Red List Criterion C thresholds.
