Common garden experiments to study local adaptation need to account for population structure

Abstract : Common garden experiments are valuable to study adaptive phenomenon and adaptive potential, in that they allow to study local adaptation without the confounding effect of phenotypic plasticity. The Q ST − F ST comparison framework, comparing genetic differentiation at the phe-notypic and molecular level, is the usual way to test and measure whether local adaptation influences phenotypic divergence between populations. Here, we highlight that the assumptions behind the expected equality Q ST = F ST under neutrality correspond to a very simple model of population genetics. While the equality might, on average, be robust to violation of such assumptions , more complex population structure can generate strong evolutionary noise. Synthesis We highlight recent methodological developments aimed at overcoming this issue and at providing a more general framework to detect local adaptation, using less restrictive assumptions. We invite empiricists to look into these methods and theorists to continue developing even more general methods.
