It has hitherto been unknown whether the paradise fish Macropodus opercularis that inhabits the Ryukyu Archipelago, Japan, is native to the region or was introduced. This study examined the genetic identity of fish from five islands in the Ryukyu Archipelago (Okinoerabu, Okinawa, Yagaji, Kume, and Minamidaito islands) and compared it with those from Taiwan Island, mainland China, and Hainan Island. Analyses of the mtDNA control (760 bp) and cytb (660 bp) regions showed that haplotypes of… Expand

Conservation and Phylogeography of Taiwan Paradise Fish, Macropodus opercularis Linnaeus
TLDR
The genetic distance and molecular phylogeny of paradise fish populations from different geographical regions: Taiwan, Singapore, and mainland China are revealed and the unique genotype in Miaoli and Taichung may imply their subdivision because of exotic input of fish from a different geographic region. Expand
Population genetic structure, diversity and stocking effect of the oriental weatherloach (Misgurnus anguillicaudatus) in an isolated island
TLDR
The genetic population structure of the oriental weatherloach in Sado Island of Japan was elucidated by phylogeographic analysis based on partial mitochondrial control region sequences, finding various haplotypes of different origins that suggest that the loach has been historically introduced to the island from various regions of Japan. Expand
Cryptic diversification of the swamp eel Monopterus albus in East and Southeast Asia, with special reference to the Ryukyuan populations
TLDR
Molecular phylogenetic analyses showed clearly that this species can be genetically delineated into three clades based on geographical populations [China–Japan (Honshu + Kyushu), Ryukyu Islands, and Southeast Asia clades], with each clade exhibiting its own reproductive behavior. Expand
Mitochondrial DNA analysis reveals a unique population structure of the amphidromous sculpin Cottus pollux middle-egg type (Teleostei: Cottidae).
TLDR
The finding indicate that the unique population structure of C. pollux ME may be influenced not only by the extent of the pelagic larval phase of the species but also by the seasonal differentiation of its dispersal phase. Expand

This paper analyzes the phylogeographical patterns of amphibian and reptile lineages distributed in the Ryukyu islands south of the Tokara Gap on the basis of relevant distributional data andExpand
Phylogenetic relationships of four species of floating gobies (Gymnogobius) as inferred from partial mitochondrial cytochrome b gene sequences
TLDR
To clarify the intra- and interspecific relationships of four Gymnogobius species, it is suggested that speciation occurred mainly in the Pliocene (possibly Miocene), with G. isaza (a Lake Biwa endemic) diverging significantly earlier (probably Lake Kouga stage) than estimated in previous studies.

Biogeography and evolution of the Carassius auratus-complex in East Asia
TLDR
The results of the present study revealed the existence of two superlineages of C. auratus in East Asia that include seven lineages endemic to each of the seven regions examined, and the lack of substantial genetic separation between triploid and diploids indicates that triploids are not composed of a single independent lineage.

Genetic relationship and distribution of the Japanese wild boar (Sus scrofa leucomystax) and Ryukyu wild boar (Sus scrofa riukiuanus) analysed by mitochondrial DNA
TLDR
From phylogenetic analyses, the mtDNA of RyukyuWild boar has a distinct lineage from that of Japanese wild boar, which was classified into the Asian pig lineage. Expand
Cytochrome b Complete Sequences and RAPD Analysis of the Phylogenetic Relationships among the Fishes of the Genus Macropodus
TLDR
The results indicated that M.hongkongensis is a valid species and M.chinensis and other Macropodus represent two independently evolving natural groups of the same monophyletic group. Expand
