Further to an earlier response by AJR Hickey on the forum (Heredity, in press) to Berlin et al.’s paper on low mitochondrial diversity in birds, Nick Lane now contributes his thoughts on the subject.

After reading with interest an article by Berlin et al. (Heredity 99, 389-396) on mitochondiral variability in birds, Anthony Hickey proposes an alternative interpretation to the data showing low mtDNA diversity, which they attributed to Hill-Robertson effects.

Populations spaced further apart are expected to be more genetically distinct than populations close together. This pattern arises because neighbouring populations exchange genes.
The trend can be used to infer the magnitude of gene flow.
François Rousset has written papers showing how to calculate such estimates but some researchers – especially plant geneticists – use rival methods based on the statistic “Moran’s I”. Rousset explains why his methods are an advance on these alternatives in a recent News and Commentary published in Heredity.
