Inbreeding Depression Is Purged in the Invasive Insect Harmonia axyridis [PDF]
Current Biology, 2011 Bottlenecks in population size reduce genetic diversity and increase inbreeding, which can lead to inbreeding depression. It is thus puzzling how introduced species, which typically pass through bottlenecks, become such successful invaders. However, under certain theoretical conditions, bottlenecks of intermediate size can actually purge the alleles ...
