“…In addition, 31 CR haplotypes were found from 151 Japanese P. pungitius (Takahashi et al. 2003). As mentioned above, such a low level of mitochondrial diversity found in P. kaibarae may be attributed to its highly confined and fragmented distribution range.…”

The contemporary distribution and genetic structure of a freshwater fish provide insight into its historical geodispersal and geographical isolation following Quaternary climate changes. The short ninespine stickleback, Pungitius kaibarae, is a small gasterosteid fish occurring in freshwater systems on the Korean Peninsula and in southeast Russia. On the Korean Peninsula, P. kaibarae populations are distributed in three geographically separated regions: the NE (northeast coast), SE (southeast coast), and a limited area in the ND (Nakdong River). In this study, we used mitochondrial loci and microsatellites to investigate the evolutionary history of P. kaibarae populations by assessing their pattern of genetic structure. Our analyses revealed a marked level of divergence among three regional populations, suggesting a long history of isolation following colonization, although ND individuals showed relatively higher genetic affinity to populations from SE than those from NE. The populations from NE showed a great degree of interpopulation differentiation, whereas populations from SE exhibited only weak genetic structuring. Upon robust phylogenetic analysis, P. kaibarae formed a monophyletic group with Russian P. sinensis and P. tymensis with strong node confidence values, indicating that P. kaibarae populations on the Korean Peninsula originated from the southward migration of its ancestral lineage around the middle Pleistocene.

“…Secondary admixture between divergent populations may also result in complicated genetic population structures (Avise & Smith, 1974;Yamamoto et al, 2004a). In freshwater and euryhaline fishes, such genetic structures have been investigated on various spatial scales, and the effects of, for example, dispersal and historical events, discussed accordingly (Avise, 2000;Matsubara et al, 2001;Takahashi et al, 2003;Yamamoto et al, 2004a). There have been few studies, however, comparing the genetic structures of closely related species on a fine scale, such as within a river system (Heithaus & Laushman, 1997;Laroche et al, 1999;Swartz et al, 2004).…”

The fine scale geographic population structure of two types of nine-spined stickleback Pungitius pungitius (the widely distributed freshwater type and a local endemic, the Omono type) within the Omono River system, Japan, was investigated. A principal components analysis of allele frequencies and neighbour-joining tree for pair-wise F ST values, based on 10 allozyme loci, revealed that the Omono type was comprised of four regional groups with relatively high genetic divergence. This grouping was also supported by hierarchical analysis of molecular variance (AMOVA) with a higher variance component among the regional groups, and by an exact test with significant genotypic differentiation for all sample pairs among the regional groups. Moreover, in the clustering of individuals using the Bayesian method, most of individuals in each regional group were assigned the corresponding cluster. On the other hand, there were less pronounced regional groups of the freshwater type, although AMOVA, exact test for genotypic differentiation and Bayesian analysis indicated genetic divergence between two sampling sites in lower reach of the Omono River and other sites. The results suggest that the Omono type represented an earlier colonization, with subsequent invasion of the freshwater type.

“…The freshwater type exclusively occupies freshwater areas within river systems, whereas the brackish-water type occupies brackish-water areas, such as estuaries and lagoons. Since these two forms are reciprocally monophyletic (Takahashi et al ., 2003), the evolutionary background is differ from that of the anadromous-freshwater system in the threespine stickleback of which freshwater forms were considered to have multiple, independent origins (McKinnon and Rundle, 2002). Takata et al .…”

-Two ecologically distinct forms, fresh-and brackish-water types, of ninespine stickleback coexist in several freshwater systems on the coast of eastern Hokkaido. Recent genetic analyses of 13 allozyme loci revealed genetic separation between the two types even though their spawning grounds were in close proximity. On the other hand, there is only a small difference in mitochondrial DNA (mtDNA) sequence between the two types suggesting that they diverged quite recently or that mtDNA introgression occurred between them. To test for postzygotic reproductive isolating mechanisms and hybrid mediated gene flow, we examined the viability and reproductive performance of reciprocal F 1 hybrids. The hybrids grew to the adult size normally and both sexes expressed secondary sexual characters in the reciprocal crosses. The female hybrids were reciprocally fertile, while the male hybrids were reciprocally sterile. Histological and flow-cytometric analyses of the hybrid testis revealed that the sterility pattern was classified as 'gametic sterility,' with gonads of normal size but abnormal spermatogenesis. To our knowledge, the present finding is a novel example of one sex hybrid sterility in the stickleback family (Gasterosteidae).
