local adaptation
Fournier-Level A, Korte A, Cooper MD, Nordborg M, Schmitt J & Wilczek AM 2011 A map of local adaptation in Arabidopsis thaliana. Science 334:86-89.
- among the 797 top SNPs, only 12 SNPs were associated with fitness in more than one environment
- loci with major genetic effects were largely independent across sites
- local adaptation relies on different loci in each environment
- independent local adaptation by different genetic mechanisms may facilitate flexible evolutionary response to changing environments across the species range
