contrasting phylogeographic histories between broadly sympatric topminnows in the fundulus notatus species complex.	sympatrically distributed closely related species provide opportunities for studying evolutionary patterns of diversification. such studies must account for historical contingencies in interpreting contemporary patterns of variation. topminnows in the fundulus notatus species complex are distributed sympatrically across much of the southern and midwestern united states. throughout most of their ranges f. olivaceus is often found in headwater stream habitats, and f. notatus is more typically dist ...	2013	23887036
hybridization and reproductive isolation among syntopic populations of the topminnows fundulus notatus and f. olivaceus.	fundulus notatus and fundulus olivaceus are two closely related topminnow species that exhibit similar ecological niches and broad, largely overlapping, north american ranges extending throughout much of the mississippi river drainage as well as the coastal drainages of the gulf of mexico. previous studies have suggested that these two species are reproductively compatible despite cytogenetic differences and will hybridize when syntopic. we used nuclear and mtdna loci to assess levels of hybridi ...	2007	17210008
