INTRASPECIFIC PHYLOGEOGRAPHY OF NORTH AMERICAN HIGHLAND FISHES: A TEST OF THE PLEISTOCENE VICARIANCE HYPOTHESIS
TLDR
The distribution and mtDNA relationships among subspecies of Erimystax dissimilis are not consistent with Pleistocene vicariance, but relationships among Appalachian haplotypes are consistent with the late Pleistsocene integration of the modern Ohio River system.
Broad‐ to fine‐scale population genetic patterning in the smallmouth bass Micropterus dolomieu across the Laurentian Great Lakes and beyond: an interplay of behaviour and geography
TLDR
Testing broad‐ to fine‐scale genetic patterns among smallmouth bass Micropterus dolomieu spawning populations across their native Great Lakes range and outgroup areas reveals marked genetic differences among lake and river populations, as well as surprisingly high divergences among closely spaced riverine sites.
Genetic divergence and connectivity among river and reef spawning groups of walleye (Sander vitreus vitreus) in Lake Erie
Discerning population genetic structure is challenging for highly vagile open water animals, as contemporary gene flow may obscure historic phylogeographic patterns. We examined genetic variation
Phylogenetic Relationships and a Revised Taxonomy for North American Cyprinids Currently Assigned to Phoxinus (Actinopterygii: Cyprinidae)
TLDR
Analyses of all North American species and the Eurasian species Phoxinus phoxinus from across its range, corroborate previous, less taxon-rich molecular studies using either nuclear or mitochondrial genes, that the genus is an unnatural assemblage.
Mitochondrial DNA Variation in Johnny Darters (Pisces: Percidae) from Eastern Kentucky Supports Stream Capture for the Origin of Upper Cumberland River Fishes
TLDR
It is suggested that conservation efforts for E. susanae should focus on habitats occurring immediately above Cumberland Falls rather than in the contact zone in the Poor Fork, and that more than one event or mechanism was responsible for the isolation of fishes in the upper Cumberland River.
Notes: Mitochondrial DNA Analysis Confirms the Existence of a Genetically Divergent Walleye Population in Northeastern Mississippi
TLDR
Analysis of mitochondrial DNA of 16 walleyes from Luxapalila Creek in northeastern Mississippi confirmed the existence of a unique genetic form of walleye in the Tombigbee River drainage, but further research is required to determine whether this distinct form occurs throughout the Gulf Coast drainages of Mississippi and Alabama.
Threatened fishes of the world: Phoxinus cumberlandensis Starnes & Starnes, 1978 (Cyprinidae)
TLDR
The blackside dace seems completely intolerant of surface coal mining and these activities in the watershed of known populations should be discontinued, and land management practices that minimize siltation should be implemented.
Characterization and Evolution of Germ1, an Element that Undergoes Diminution in Lampreys (Cyclostomata: Petromyzontidae)
TLDR
The results suggest that Germ1 is a R2 retroelement that occurs in the genome of P. marinus and other petromyzontid lampreys, and that its diminution is incidental to the reduction in rDNA copies during embryogenesis.
Female Preference and the Maintenance of Male Fin Ornamentation in Three Egg-Mimic Darters (Pisces: Percidae)
TLDR
A role for female choice in the maintenance of exaggerated male fin ornamentation in these species of egg-mimic darters is demonstrated.
