How Vibe analyzers were used
A long-term study genotyped and tracked a wild wheat population over 36 years, finding stable genetic clustering by ecological microhabitats and evidence consistent with fine-scale local adaptation.
Study overview
Long-term genetic studies of wild populations are rare but important for connecting ecological and population-genetics models. This work genotyped 832 individuals sampled over 36 years at high spatial resolution and found genotypes clustered by ecological microhabitats over tens of meters, with remarkable stability over time. Simulations suggest limited dispersal alone is unlikely to explain the stability, and a common-garden experiment showed phenotypic differences among microhabitat genotypes, supporting fine-scale local adaptation.
