“…Allelic richness and heterozygosity per population were similar to other unionid species (Eackles and King, 2002), but much higher than European Margaritifera margaritifera (Geist and Kuehn, 2005). This trend was also found in a previous allozyme study of C. monodonta (Monroe, 2008).…”

Phylogeographic and population genetic analyses reveal Pleistocene isolation followed by high gene flow in a wide ranging, but endangered, freshwater mussel

Freshwater organisms of North America have had their contemporary genetic structure shaped by vicariant events, especially Pleistocene glaciations. Life history traits promoting dispersal and gene flow continue to shape population genetic structure. Cumberlandia monodonta, a widespread but imperiled (IUCN listed as endangered) freshwater mussel, was examined to determine genetic diversity and population genetic structure throughout its range. Mitochondrial DNA sequences and microsatellite loci were used to measure genetic diversity and simulate demographic events during the Pleistocene using approximate Bayesian computation (ABC) to test explicit hypotheses explaining the evolutionary history of current populations. A phylogeny and molecular clock suggested past isolation created two mtDNA lineages during the Pleistocene that are now widespread. Two distinct groups were also detected with microsatellites. ABC simulations indicated the presence of two glacial refugia and post-glacial admixture of them followed by simultaneous dispersal throughout the current range of the species. The Ouachita population is distinct from others and has the lowest genetic diversity, indicating that this is a peripheral population of the species. Gene flow within this species has maintained high levels of genetic diversity in most populations; however, all populations have experienced fragmentation. Extirpation from the center of its range likely has isolated remaining populations due to the geographic distances among them.

“…These deviations might arise because of one or a combination of factors, such as the substructure of samples caused by the pooling of samples from several different sites, inbreeding, or the presence of null alleles (Zouros and Foltz, 1984). The presence of null alleles is assumed to cause the heterozygote deficiency observed in several bivalve species, such as the geoduck clam, European flat oyster, and pink mucket (Launey et al, 2002;Eackles and King, 2002;Vadopalas et al, 2004). The presence of null alleles might represent a major limitation in the cross-species transfer of microsatellite markers (Barbará et al, 2007).…”

ABSTRACT. Korean (hard-shelled) mussels (Mytilus coruscus) are an economically important endemic marine bivalve mollusk of Korea; yet, the population has rapidly declined because of overharvesting and habitat competition from the invasive Mytilus galloprovincialis species. The population structures of M. coruscus and M. galloprovincialis were analyzed by next-generation sequencing using 5 microsatellite markers specifically developed for M. coruscus. M. galloprovincialis had an average of 5.4 alleles per locus (range = 2-10), with an average allelic richness of 4.9 per locus (range = 2.0-9.3). M. coruscus had an average of 5.7 alleles per locus (range = 2-13), with an average allelic richness of 5.2 per locus (range = 2.0-11.9). Excessive homozygosity was observed at 3 loci, which was assumed to be due to the presence of null alleles at these loci. Pairwise multilocus F ST estimates showed that the M. coruscus and M. galloprovincialis populations were clearly separated. Six populations of M. galloprovincialis from the western, eastern, and southern coast of Korea formed 2 separate clusters, indicating that more than 2 populations of M. galloprovincialis have been introduced to the Korean Peninsula.

Further genetic information is required to perform selective breeding, population management, and restoration of M. coruscus.

“…Many populations of M. margaritifera both within and among river drainages had unique alleles and high pairwise F ST values and genetic distances (Geist and Kuehn 2005;Nei 1972;Weir and Cockerham 1984). Similarly, using microsatellites developed by Eackles and King (2002), populations of Lampilis cariosa along the Atlantic coast of Maine showed significant population structure (Kelly and Rhymer 2005). Genetic variation between unionoid populations draining into salt water would be expected to be high as there would be much less opportunity for the transport of glochidia by host fish between populations.…”

“…Five published sets of microsatellite loci have been developed for five unionoid species (Eackles and King 2002;Geist et al 2003;Jones et al 2004;Shaw et al 2006;Zanatta and Murphy 2006). Significant population structure was found in the European pearl mussel (Margaritifera margaritifera) using microsatellite markers (Geist and Kuehn 2005).…”

The northern riffleshell (Epioblasma torulosa rangiana) is a critically endangered unionoid species in need of conservation throughout its range. It is the only unionoid to be federally protected in both Canada and the U.S. We use sequences from two mtDNA genes and 15 microsatellite loci to assess genetic variation among 86 individuals from the four populations in the three remaining drainages in which E. t. rangiana is known to be reproducing. All of these populations are in formerly glaciated landscapes that emerged <10 kya. The mtDNA sequence data do not indicate significant geographic structure among the populations. However, allelic data from the microsatellite loci reveal highly significant population structuring. Individuals of E. t. rangiana can be assigned to their own river of origin with 98.8% accuracy. Significant isolation-by-distance occurs. This analysis will be useful to conservation managers in documenting the genetic structure, patterns of isolation, and genetic variability within and among populations of E. t. rangiana.
