In ecological speciation, incipient species diverge due to natural selection that is ecologically based. In flowering plants, different pollinators could mediate that selection (pollinator-mediated divergent selection) or other features of the environment that differ between habitats of two species

Excel spreadsheet comparing expected heterozygosity and FST at SNP loci, along with actual base counts from reads. Comparison is between the Greater Sage-grouse and Gunnison Sage-grouse samples, ie it does not include the Bi-state population for this analysis.
