title: Data from: The influence of life-history strategy on genetic differentiation and lineage divergence in darters (Percidae: Etheostomatinae)

description: Recent studies determined that darters with specialized breeding
 strategies can exhibit deep lineage divergence over fine geographic scales
 without apparent physical barriers to gene flow. However, the extent to
 which intrinsic characteristics interact with extrinsic factors to
 influence population divergence and lineage diversification in darters is
 not well understood. This study employed comparative phylogeographic and
 population genetic methods to investigate the influence of life-history on
 gene flow, dispersal ability, and lineage divergence in two sympatric
 sister darters with differing breeding strategies. Our results revealed
 highly disparate phylogeographic histories, patterns of genetic structure,
 and dispersal abilities between the two species suggesting that
 life-history may contribute to lineage diversification in darters,
 especially by limiting dispersal among large river courses. Both species
 also showed striking differences in demographic history, indicating that
 extrinsic factors differentially affected each species during the
 Pleistocene. Collectively, our results indicate that intrinsic and
 extrinsic factors have influenced levels of gene flow among populations
 within both species examined. However, we suggest that life-history
 strategy may play a more important role in lineage diversification in
 darters than previously appreciated, a finding that has potentially
 important implications for understanding diversification of the rich North
 American freshwater fish fauna.

 GENEPOP formatThe microsatellite DNA
 data file is in GENEPOP format. The file includes genotype scores for
 seven darter specific microsatellite loci. Locus names are listed under
 the title line at the top of the file. POP refers to populations described
 in the manuscript. The six populations are ordered as follows (CB, DD,
 CH/SH, NF/SF, SW, and FL). Each row below POP identifiers represents an
 individual followed by their genotype for the seven loci. Allele scores
 for each locus are concatenated into six digits, with the first three
 numbers representing the size of allele "one" and the second
 three numbers representing the size of allele "two". Missing
 data are coded as "000".E_boschungi_GENEPOP.txtEtheostoma tuscumbia GENEPOP formatThe microsatellite DNA data file is in GENEPOP format.
