Strong, recent selective sweeps reshape genetic diversity in freshwater bivalve Megalonaias nervosa

  title={Strong, recent selective sweeps reshape genetic diversity in freshwater bivalve Megalonaias nervosa},
  author={Rebekah L. Rogers and Stephanie L. Grizzard and Jeffrey T. Garner},
Freshwater Unionid bivalves have recently faced ecological upheaval through pollution, barriers to dispersal, human harvesting, and changes in fish-host prevalence. Currently, over 70% of species are threatened, endangered or extinct. To characterize the genetic response to these recent selective pressures, we collected population genetic data for one successful bivalve species, Megalonaias nervosa. We identify megabase sized regions that are nearly monomorphic across the population, a signal… Expand

Figures from this paper


Unioverse: A phylogenomic resource for reconstructing the evolution of freshwater mussels (Bivalvia, Unionoida).
The utility of this phylogenomic resource is demonstrated by estimating a backbone phylogeny of the Bivalvia with a focus on the Unionoida, reconstructing the subfamily-level relationships of the Unionidae, and recovering the systematic position of the phylogenetically unstable genus Plectomerus. Expand
Molecular phylogeny of the Nearctic and Mesoamerican freshwater mussel genus Megalonaias
The reconstructed molecular phylogeny and the observed genetic diversity suggests that Megalonaias is a monotypic genus and that Megonaias nickliniana, currently considered a federally endangered species, is not a valid species. Expand
Phylogeny of North American amblemines (Bivalvia, Unionoida): prodigious polyphyly proves pervasive across genera
Parsimony and Bayesian analyses suggest that most amblemine genera, as currently defined, are polyphyletic, and the extent of Amblemini and the relationships of some genera previously assigned to that tribe remain unclear. Expand
A High-Quality Reference Genome for a Parasitic Bivalve with Doubly Uniparental Inheritance (Bivalvia: Unionida)
A genome assembly of Potamilus streckersoni is presented using Pacific Bioscience single-molecule real-time long reads and 10X Genomics-linked read sequencing and RNA sequencing from multiple tissue types and life stages to annotate the reference genome. Expand
Genome Survey of the Freshwater Mussel Venustaconcha ellipsiformis (Bivalvia: Unionida) Using a Hybrid De Novo Assembly Approach
This resource opens the way to comparative genomics studies to identify genes related to the unique adaptations of freshwater mussels and their distinctive mitochondrial inheritance mechanism. Expand
Effects of Alien Species on Freshwater Mollusks in North America

Because of ineffective control of aliens in North America, they may be an increasingly important factor in molluscan distribution as new species arrive from other continents and established species spread throughout the continent. Expand
Fish and mussels: Importance of fish for freshwater mussel conservation
A synthesis of published evidence on the fish–mussel relationship is provided to explore possible patterns in co-extinction risk, a variety of threats that may negatively affect fish species, and the concomitant impacts on freshwater mussels are identified. Expand
Parallel and nonparallel genomic responses contribute to herbicide resistance in Ipomoea purpurea, a common agricultural weed
It appears that the physiological mechanism of resistance in this species is likely the same among resistant populations, but patterns of both similar and divergent selection across separate resistant populations at particular loci are found. Expand
Tandem Duplications and the Limits of Natural Selection in Drosophila yakuba and Drosophila simulans
The span of standing variation will define evolutionary outcomes in spite of convergence across gene ontologies consistent with rapidly evolving phenotypes, indicating that evolution will be strictly limited by mutation even in organisms with large population sizes. Expand
Biodiversity on the brink: an assessment of conservation strategies for North American freshwater mussels
Identification of factors that eliminated mussels from many otherwise intact streams is critical and Translocation and captive propagation will be key elements in reestablishing mussel assemblages in restored habitats, but these techniques should be used with caution and primarily to increase the occurrence of a species throughout its historical range.
