Isolation by environment explains why the grass isn’t always greener

Ever since Sewall Wright introduced isolation by distance in 1943, the interplay between genetic differentiation and geographic distance has been a foundational, sometimes frustrating, aspect of population genetics studies. But distance isn’t just distance. The walk to my car isn’t any longer when … Continue reading

The latest gadget for the molecular ecologist’s toolkit

Designing a sampling scheme to collect an organism of interest for a population genetic/genomic study can be fraught with difficulty. How best to sample? Randomly? Or, along a grid? How many individuals to sample? Thirty? Or, perhaps, the sample size … Continue reading
