Clinal variation is one of the most emblematic examples of the action of
natural selection at a wide geographical range. In Drosophila subobscura
parallel clines in body size and inversions, but not in wing shape, were
found in Europe and South and North America. Previous work has shown that
a bottleneck effect might be largely responsible for differences in wing
trait-inversions association between one European and one South American
population. One question still unaddressed is if the associations found
before are present across other populations of the European and South
American clines. Another open question is whether evolutionary dynamics in
a new environment can lead to relevant changes in wing traits-inversions
association. In order to analyze geographical variation in these
associations, we characterized three recently laboratory founded
Drosophila subobscura populations from both the European and South
American latitudinal clines. To address temporal variation, we also
characterized the association at a later generation in the European
populations. We found that wing size and shape associations can be
generalized across populations of the same continent, but may change
through time for wing size. The observed temporal changes are probably due
to changes in the genetic content of inversions, derived from adaptation
to the new, laboratory environment. Finally, we show that it is not
possible to predict clinal variation from intrapopulation associations.
All in all this suggests that, at least in the present, wing
traits-inversion associations are not responsible for the maintenance of
the latitudinal clines in wing shape and size.
Raw Data and Average statisticsIn this excel book you can find the raw
data for the three populations analyzed in each continent (Europe and
South America) and the two generations of the European populations
analyzed (6 and 25). Additionally, there are also tables with the basic
statistics (average and standard deviation) of centroid size and wing
shape for each inversion analyzed, separated by replicate population and
generation.Simulations and BootstrapR code used to generate the
simulations of the association between centroid size and standard dose and
the bootstrap of the observed associations.
