| Summary: | (sequential) divergences were the Apalachicola clade (during across the Gulf Coastal Plain. The Apalachicola clade was and lineages within the Western clade (during the late C. enusta was present in the southeastern United States C. v. stigmatura. Phylogenetic analyses of mtDNA C. venusta collected throughout the range of the species clades: these were termed Apalachicola, Mobile, and Western clades. The Western clade included four distinct lineages, cluster analysis. Cyprinella galactura and Cyprinella correspond to previously hypothesized zones of vicariance. Cyprinella venusta. Taxonomically, C. venusta is comprised during late Miocene - early Pliocene times. Subsequent early Pleistocene. observed phylogeographic discontinuities employed maximum parsimony, Neighbor-joining, and UPGMA involved the Apalachicola and Mobile Bay drainages, and levels of the Gulf of Mexico during the late Pliocene and lineages exhibited an east to west pattern of divergence lineages of blacktail shiners collected from the range of C. lineages within the Western clade may correspond to elevated lutrensis were used as outgroups for the analyses. Maximum Mitochondrial (mt)DNA restriction-site analysis was used to most basal and sister the Mobile clade and the Western clade. Neighbor-Joining and UPGMA clustering generally supported nucleotide-sequence divergence among clades, indicated that - of C. v. stigmatura formed the Mobile clade; the Pearl of three subspecies: C. v. venusta, C.v. cercostigma, and parsimony analysis revealed three major phylogeographic Pascagoula lineage and Apalachicola clades were comprised of phylogenetic analyses, combined with estimates of mtDNA Pliocene - early Pleistocene). Isolation of the four restriction-sites assayed from 20 geographic populations of results from maximumparsimony analysis. Results of shiners from the range of C. v. enusta. The clades and study systematics and biogeography of the blacktail shiner, termed PearlPascagoula, Mississippi, East Texas, and West Texas lineages were comprised of lineages of blacktail Texas lineages. Blacktail shiners collected from the range The Apalachicola, Mobile, and Western clades merit elevation the early Pliocene), Mobile clade (during the mid-Pliocene), to species status. v. cercosticrma; and the Mississippi, East Texas and West |
