Using dense locality sampling resolves the subtle genetic population structure of the dispersive fish species Plecoglossus altivelis

In dispersive species with continuous distributions, genetic differentiation between local populations is often absent or subtle and thus difficult to detect. To incorporate such subtle differentiation into management plans, it may be essential to analyse many samples from many localities using adequate numbers of high-resolution genetic markers. Here, we evaluated the usefulness of dense locality sampling in resolving genetic population structure in the ayu (Plecoglossus altivelis), a dispersive fish important in Japanese inland fisheries. Genetic variability in, and differentiation between, ayu populations around the Japan-Ryukyu Archipelago were investigated in 4746 individuals collected from 120 localities by genotyping 12 microsatellite markers. These individuals represented the two subspecies of ayu, namely the Ryukyuan subspecies (Plecoglossus altivelis ryukyuensis) and both amphidromous and landlocked forms of the nominotypical subspecies (P. a. altivelis) along the archipelago. We successfully detected an absence of genetic differentiation within the landlocked form and subtle but significant differentiation and clear geographic patterns of genetic variation among populations of the amphidromous form, which had been considered genetically homogeneous. This suggests that dense locality sampling effectively resolves subtle differences in genetic population structure, reducing stochastic deviation in the detection of genetic differentiation and geographic patterns in local populations of this dispersive species. Resampling analyses based on empirical data sets clearly demonstrate the effectiveness of increasing the number of locality samples for stable and reliable estimations of genetic fixation indices. The genetic population structure observed within the amphidromous form provides useful information for identifying management or conservation units in ayu.

“…A parent fish defends the eggs until the hatching of the larvae, and the larvae then drift along the shore, forming cohorts. We have previously undertaken a large‐scale study of genetic differentiation among populations of C. annularis , and have shown that this species consists of several geographical groups, of which the structure reflects the historical vicariance caused by environmental changes around the Japanese archipelago (Hirase et al in press). In addition, this study also revealed a high level of genetic differentiation within the geographical groups, suggesting the low dispersal ability of C. annularis.…”

Evidence of the restricted gene flow within a small spatial scale in the Japanese common intertidal goby Chaenogobius annularis

et al. 2012

Elucidating the scale of gene flow among populations is an important challenge for understanding the ecological dynamics and local adaptation of marine organisms. We assessed whether gene flow is restricted even at a small spatial scale in the Japanese common intertidal goby Chaenogobius annularis, using highly polymorphic DNA markers, involving the mitochondrial DNA (mtDNA) control region and 15 microsatellite DNA (msDNA), because past ecological studies have suggested low dispersal ability for rocky intertidal fishes. We found significant heterogeneities between four neighboring local populations by both mtDNA and msDNA analyses. In addition, no genetic heterogeneity was detected by either method across generations within a population; it was considered that such genetic differentiation is retained across generations and that the gene flow of this species is restricted to within a radius of a few kilometers. This is the first report showing a clear genetic subdivision in rocky intertidal fish.

“…The existence of genetically distinct groups has also been reported for some shallow-water marine fish species in the northwestern Pacific: Chelon haematocheilus (Liu et al 2007), Ammodytes personatus (Han et al 2012), and Chaenogobius annularis (Hirase et al 2012). This demonstrates that isolation in the deep-sea basin is not the unique cause of genetic breaks among marine fish species in this area.…”

Abstract:The Sea of Japan is a semi-closed marginal sea where genetic break and/or speciation have been reported for some deep-sea taxa. Population structure was compared between the congeneric deep-sea flounder species Hippoglossoides dubius and H. pinetorum inhabiting the Sea of Japan and neighboring seas. Based on nucleotide sequences of mitochondrial control regions, the H. dubius population was concluded to be genetically homogeneous, while 2 genetically distinct groups were recognized among H. pinetorum. Although the rare group of H. pinetorum populates the Sea of Japan, the Yellow Sea, the Okhotsk Sea, and the northwestern Pacific, frequency was the highest in the Sea of Japan. The unique phylogeographic pattern of H. pinetorum may be attributable to secondary contact with the Sea of Japan lineage, which was isolated from other sea areas during the last glacial period. A difference in bathymetrical distribution between the two species might explain their contrasting genetic population structures.
