Range expansion in the North American starling invasion

In a range-wide survey of genomic markers, I found that starlings in North America may have adapted to local environmental conditions despite a genetic bottleneck and negligible isolation-by-distance.

Like other rapidly expanding species, starlings may have evolved dispersal and/or migration strategies that facilitated expansion across most of North America in just a few decades. Right now, I am exploring how drivers of invasion success may work in concert to support expansion.
