Do refugial populations exhibit greater genetic diversity?

Abstract

The  genetic consequences of the survival of plant populatiom in glacial refugia are contradictory. Many authors suggest that putative refugial populations harbour higher levels of genetic diversity relative to their likely descendant populations. Others assume a massive loss of allelic variability in refugial populations through inbreeding. founder events and population bottlenecks, at least if refugial areas and population size are small.
