Here we present a correction to our article "Evolutionary dynamics of molecular markers during local adaptation: a case study in Drosophila subobscura". We have recently detected an error concerning the application of the Ln RH formula – a test to detect positive selection – to our microsatellite data. Here we provide the corrected data and discuss its implications for our overall findings. The corrections presented here have produced some changes relative to our previous results, namely in a locus (dsub14) that presents indications of being affected by positive selection. In general, our populations present less consistent indications of positive selection for this particular locus in both periods studied – between generations 3 and 14 and between generation 14 and 40 of laboratory adaptation. Despite this, the main findings of our study regarding the possibility of positive selection acting on that particular microsatellite still hold. As previously concluded in our article, further studies should be performed on this specific microsatellite locus (and neighboring areas) to elucidate in greater detail the evolutionary forces acting on this specific region of the O chromosome of Drosophila subobscura.
We have recently detected an error in our article , concerning the application of the Ln RH formula to our microsatellite data. This necessitates some changes in the results and figures presented in the "Testing for positive selection during laboratory adaptation" results section. Here we provide the corrected data and discuss its implications for our overall findings.
In general, we conclude that our main findings regarding the action of positive selection in our study hold, since our data is still suggestive of a deviation from neutral expectations in locus dsub14, although the signal is less pronounced than reported before. Nevertheless, as previously concluded , more studies should be conducted in this specific microsatellite locus (and neighboring areas) to further elucidate the evolutionary forces acting on this specific region of the O chromosome.
We regret any inconvenience that this error in our data might have caused the readers.
