Summarizing these results, there appear to be three general patterns of fairy shrimp
variation: (1) low to moderate divergence (with some exceptions) among populations on a scale of a few kilometers or less; (2) much greater divergence among more distantly separated populations, but no strong relationship between geographic distance and genetic divergence; (3) evidence of rare long-distance dispersal and gene flow.
