Spatial population structure plays an important role in species persistence, evolution and
conservation. Benthic stream fishes are diverse and frequently imperilled, yet the …

Copy number variants (CNVs) represent a substantial source of genomic variation in
vertebrates and have been associated with numerous human diseases. Despite this, the …

Conservation management of threatened species requires identifying the landscape
features that shape population structure. Within river ecosystems, the dendritic nature of river …

Genetic differentiation in aquatic systems is often driven by geographic distance (isolation by
distance) due to the linear and hierarchical distribution of populations, but habitat …

Abstract Knowledge of the genetic structure and cryptic diversity is essential for the
conservation of endangered species. We conducted a genetic survey of the federally …

Abstract The Kentucky Arrow Darter (Etheostoma sagitta spilotum) is federally listed as
threatened and known only from five tributary systems in the Kentucky River system …

Genetic connectivity is expected to be lower in species with limited dispersal ability and a
high degree of habitat specialization (intrinsic factors). Also, gene flow is predicted to be …

Recent studies determined that darters with specialized breeding strategies can exhibit
deep lineage divergence over fine geographic scales without apparent physical barriers to …

To evaluate the conservation status of a species or population it is necessary to gain insight
into its ecological requirements, reproduction, genetic population structure, and overall …

Despite the high diversity and endemism in the Mobile River Basin, analyses of molecular
phylogeographic patterns of freshwater fishes in this system are lacking. Using cytochrome b …
