“…However, there are no reports on the genetic structure of S. marmoratus populations that cover most of the habitat, from Japan to China. Microsatellite markers used in the exploration of population genetic structure usually exhibit co‐dominant inheritance and high diversity, with relatively modest analysis expense (Chong & Roe, ; Du et al, ; Kitson‐Walters et al, ). This study aimed to draw a comprehensive picture of the patterns of genetic diversity and structure along the distribution area in the coastal waters of the northwestern Pacific, across a large latitudinal range, using microsatellite markers.…”

The marbled rockfish (Sebastiscus marmoratus) is an important species that is widely distributed across the marginal seas of the northwestern Pacific. Several kinds of DNA markers, such as amplified fragment length polymorphisms (AFLP), mitochondrial DNA (mtDNA) and single nucleotide polymorphisms (SNPs), have been used to assess the population genetic characteristics of this species in previous studies. However, there have been no genetic profiling studies to cover the entire distribution. Here, six highly polymorphic microsatellite markers were applied to 18 populations across a spatially large area (from the Sea of Japan in the north to the South China Sea in the south). The results showed that the whole population exhibits high, stable genetic diversity, low relatedness and large effective population size. There was very weak genetic differentiation overall and no isolation by distance occurred among the populations, which may be attributed to significant contemporary gene flow, each generation. The above results may lead us to infer that the recent S. marmoratus population structure could be considered as one large integrated population. The present study will be beneficial to population conservation and fisheries management of S. marmoratus and will lead to better insights into the genetic characteristics of other species that belong to the Sebastidae family.

“…Host fish vagility may also be an important factor on the population structure observed in the Sheepnose. Previous studies on freshwater mussels have invoked host fishes as contributing to or reinforcing the population structure (Chong & Roe, 2018; Zanatta & Wilson, 2011). The most recent information indicates that hosts of the Sheepnose include cyprinids (Hove et al, 2015) which may lack the dispersal capabilities of larger riverine fishes (Comte & Olden, 2018) and therefore contribute to the isolation between populations and demes.…”

North American freshwater mussel species have experienced substantial range fragmentation and population reductions. These impacts have the potential to reduce genetic connectivity among populations and increase the risk of losing genetic diversity. Thirteen microsatellite loci and an 883 bp fragment of the mitochondrial ND1 gene were used to assess genetic diversity, population structure, contemporary migration rates, and population size changes across the range of the Sheepnose mussel (Plethobasus cyphyus). Population structure analyses reveal five populations, three in the Upper Mississippi River Basin and two in the Ohio River Basin. Sampling locations exhibit a high degree of genetic diversity and contemporary migration estimates indicate that migration within river basins is occurring, although at low rates, but there is no migration is occurring between the Ohio and Mississippi river basins. No evidence of bottlenecks was detected, and almost all locations exhibited the signature of population expansion. Our results indicate that although anthropogenic activity has altered the landscape across the range of the Sheepnose, these activities have yet to be reflected in losses of genetic diversity. Efforts to conserve Sheepnose populations should focus on maintaining existing habitats and fostering genetic connectivity between extant demes to conserve remaining genetic diversity for future viable populations.

“…Recent anthropogenic processes such as habitat destruction and fragmentation often lead to reduced population sizes and connectivity, reducing the genetic diversity and increasing the genetic differentiation 4 . In addition, life history traits and species interactions affect the genetic structure of populations at different spatial and temporal scales 5 .…”

Many landscape and biotic processes shape the genetic structure of populations. The genetic structure of species with parasitic stages may also depend on the life history and ecology of their host. We investigated population genetic structure of the mussel Margaritifera margaritifera in Southern Sweden, and in relation to the population size and life history of its hosts, Salmo trutta and S. salar. Mussel populations were genetically differentiated into two clusters, further subdivided into four clusters and distinct conservation units. Regardless of host species, the genetic differentiation was lower among mussel populations sustained by sea-migrating than by resident hosts, while the genetic diversity was higher in mussel populations sustained by sea-migrating than by resident hosts. Genetic diversity of mussel populations was positively related to host abundance. Mussel population size was positively related to high genetic diversity of mussels sustained by resident hosts, while low mussel population size sustained by sea-migrating hosts had a high genetic diversity. The results of our study suggest a combined influence of mussels and host fish on genetic structure of unionoid mussels. We suggest to conserve not only mussel population sizes and host fish species, but also consider host migratory/resident behaviour and abundance when designing conservation programs.
