“…The three-spined stickledback ( Gasterosteus aculeatus ) was shown to suffer from search inefficiency in humic water, possibly due to limited plasticity in opsin expression [63, 64]. Hendry [65] asserted that plasticity in an important fitness-related trait could help species colonize; therefore, adult opsin expression plasticity may enable red shiners to successfully adapt to new aquatic environments and thrive in the newly invaded areas [66–69].…”

“…Nandamuri et al [28] suggested that the geographic history of Lake Malawi, fluctuating between being a “green” and “blue” lake [77], generates a selective force to maintain plasticity. The red shiner’s wide distribution range encompasses a large variety of aquatic habitats [48], which could serve as a similar force to maintain plasticity in opsin gene expression; moreover, high genetic diversity in the species and gene flow among conspecific and heterospecific lineages may suppress the influence of genetic drift [69, 78, 79]. Further studies on the demographic and biogeographic history of the red shiner, in addition to studies on opsin expression plasticity in other closely related leuciscid fishes, would help to answer whether the geographic history of North America and/or phylogenetic constraints help preserve plasticity.…”

Vision is very important to fish as it is required for foraging food, fighting competitors, fleeing from predators, and finding potential mates. Vertebrates express opsin genes in photoreceptor cells to receive visual signals, and the variety of light levels in aquatic habits has driven fish to evolve multiple opsin genes with expression profiles that are highly plastic. In this study, red shiners ( Cyprinella lutrensis ) were exposed to four water turbidity treatments and their opsin genes were cloned to elucidate how opsin gene expression could be modulated by ambient light conditions. Opsin gene cloning revealed that these fish have single RH1 , SWS1 , SWS2 and LWS genes and two RH2 genes. Phylogenetic analysis also indicated that these two RH2 opsin genes– RH2A and RH2B –are in-paralogous. Using quantitative PCR, we found evidence that opsin expression is plastic in adults. Elevated proportional expression of LWS in the cone under ambient light and turbid treatment indicated that the red shiner’s visual spectrum displays a red shift in response to increased turbidity.

“…Evidence of morphological variability in widely distributed taxa, including species that have been considered monotypic based on some external characteristics (Contreras‐Balderas, ; Johnston & Ramsey, ), raises the possibility, however, that widespread leuciscids are complexes of distinct lineages. Recent assessments of morphological and genetic variation that have revealed unexpected patterns of differentiation and complexity in widespread Nearctic and Palearctic groups also indicate that there is likely greater diversity in the family than is currently recognized (Blum et al ., ; Glotzbecker et al ., ; Kottelat, ; Palandacic et al ., , ; Schönhuth et al ., , , ). As many widespread leuciscids are often dominant constituents of fish assemblages, this suggests that current estimates of Nearctic and Palearctic fish diversity are conservative and that there are additional evolutionary lineages than are currently recognized.…”

“…Morphological analyses of Phoxinus Rafinesque 1820 from Italy and the western Balkans described four additional species (Bianco & De Bonis, ), though some incongruencies were found in subsequent molecular analyses (Palandacic et al ., ). Studies of widely distributed Nearctic leuciscids, including species of Campostoma Agassiz 1855 (Blum et al ., ; Schönhuth et al ., ), Cyprinella Girard 1856 (Glotzbecker et al ., ) and Dionda Girard 1856 (Schönhuth et al ., ), have uncovered similar evidence of unrecognized diversity, leading to the resurrection of previously described species and the discovery of new lineages that probably warrant species recognition.…”

The extent and nature of genetic differentiation in Semotilus atromaculatus, one of the most abundant and widespread leuciscids in North America, were evaluated based on mitochondrial (mt) and nuclear DNA sequence variation. Phylogenetic relationships were first inferred based on a fragment of the cytochrome b (cytb) region and the nuclear intron s7 gene for S. atromaculatus and all other congeners as well as representative species from all other genera in the creek chub-plagopterin clade. The phylogeography of major haplogroups of S. atromaculatus was also assessed according to variation in a fragment of the mitochondrial cytb region from 567 individuals across its range. All analyses identified S. thoreauianus, S. lumbee and S. corporalis as reciprocally monophyletic groups. Analyses of nuclear sequence variation resolved S. atromaculatus as a single clade, where S. thoreauianus and S. lumbee were recovered as the sister group to S. atromaculatus, and S. corporalis was resolved as sister to all other species in the genus. Analyses of mtDNA sequence variation recovered S. atromaculatus as three well supported and differentiated monophyletic groups, with a widespread genetically homogeneous lineage extending across most of the current range of the species; a more geographically restricted and geographically structured lineage in the southern Appalachians, sister group to S. lumbee; and a geographically restricted lineage was identified from two Gulf Slope basins. Evidence of complex mito-nuclear discordance and phylogeographic differentiation within S. atromaculatus illustrates that further analysis of widespread species is warranted to understand North American freshwater fish diversity and distributions.

“…Although natural processes can sub-divide populations and promote diversification, human activities can obscure natural evolutionary patterns [ 4 – 6 ]. The translocation of species outside of their native range is arguably one of the most important human mediated factors that complicates native species distribution patterns [ 4 , 7 – 9 ]. For species with extensive geographic structuring, disentangling natural and human-mediated factors affecting their distribution can be difficult, but is critical to the development of management plans for protecting species and their role within ecosystems.…”

Connections and containers: Using genetic data to understand how watershed evolution and human activities influence cutthroat trout biogeography

Species with large geographic distributions often exhibit complex patterns of diversity that can be further complicated by human activities. Cutthroat trout (Oncorhynchus clarkii) are one of the most widely distributed freshwater fish species in western North America exhibiting substantial phenotypic and genetic variability; however, fish stocking practices have translocated populations outside of their native range and may have obscured intraspecific boundaries. This study focuses on cutthroat trout populations representing three distinct evolutionary clades that are found intermixed within a contact zone between the Bonneville and upper Snake River watersheds in the western United States. We used mitochondrial and microsatellite genetic data, as well as historical stocking records, to evaluate whether populations of cutthroat trout in the contact zone are native or are introduced. We found significant genetic differentiation and fine-scale genetic population structure that was organized primarily by watershed boundaries. While we detected increased genetic diversity in some areas in close proximity to the greatest number of stocking events, the highly organized population structure both within and between areas of the contact zone indicates that the populations are native to the watersheds. Intermixing of distinct evolutionary lineages of cutthroat trout appears to be the result of historical connections between paleodrainages. Our analyses provide a context for understanding how genetic data can be used to assess the status of populations as native or introduced.
