Patch turnover rate governs mutant fate when extinction outpaces migration

Evidence

Rates of migration might often have to be intermediate, since too much or too little migration among demes could fail to provide for polymorphism (Gillespie, 1975, 1978). For example, Slatkin (1981a,b) showed that if the local extinction rate is greater than the migration rates among neighboring demes, the fate of new mutants would be more dependent on the extinction time scale (i.e., patch turnover rate) than on the rates of migration. — S.
