“…3). This result agrees with previous studies (Yang et al 2016; Zhou et al 2017). The WY Range is located in the central and southern regions of Hainan Island and approaches an elevation of 1800 m. The landforms reflect that the rivers on island originate from the central mountainous area and flow outwards.…”

“…Due to the steep topology of the island, most rivers run directly into the oceans with no connection to the neighboring drainage systems. As in previous phylogeographic studies of freshwater fishes (Yang et al 2016; Zhou et al 2017), the WY Range was an important barrier. Zhou et al (2017) found that the populations of the cyprinid fish O. lepturum on Hainan Island could be divided into three units based on their location in the Qiongzhou Strait, the Gulf of Tonkin and the South China Sea.…”

“…Genomic DNA was extracted from muscle tissue using a Genomic DNA Purification Kit (Gentra Systems, Valencia, CA). The entire cyt b gene and control region fragment were amplified by polymerase chain reaction (PCR) using primers from Xiao et al (2001) and Zhou et al (2017), respectively. Each 50 µl PCR mixture contained 5 ng template DNA, 5 µl 10x reaction buffer, 5 µl dNTP mix (10 mM), 5 pmol of each primer and 2 U of Taq polymerase (Promega, Madison, WI, U.S.A.).…”

“…According to the landforms, the WY Range isolated these four rivers into two regions, southern Hainan (Wanquan and Linshui rivers) and northern Hainan (Nandu and Changhua Rivers). Yang et al (2016) and Zhou et al (2017) proposed that the WY Range was an important phylogeographic break based on the population structures of the cyprinid fishes G. orientalis and Onychostoma lepturum . However, Lin et al (2016) suggested that the WY Range did not act as a barrier to gene flow among populations of another cyprinid, O. hainanensis .…”

Aphyocypris normalis (Teleostei: Cyprinidae) is an endemic species in South China, but little is known about its genetic structure. This study examined the population structure of A. normalis using sequences of the mitochondrial DNA control region and cytochrome b gene (2,086 bp). In total, 107 specimens were collected from nine populations. All 105 mtDNA haplotypes were identified as belonging to two allopatric phylogroups. The results of a statistical dispersal-vicariance analysis (S-DIVA) suggested that the ancestral populations of A. normalis were distributed widely on Hainan Island and east of the Leizhou Peninsula. A comparison of the fixation indices NST (0.532) and GST (0.004) revealed that the phylogeny and geography had a significant relationship. Our study found that (1) the Wuzhishan and Yinggeling Mountain Range was an important barrier limiting gene exchange between populations on both sides; (2) cyclic climate changes may have shaped migrations and population differentiations; and (3) different colonization times caused different population diversities between codistributed species. In addition, the inter- and intraspecific diversities of the genus Aphyocypris were estimated.

Phylogeographic structure of the dwarf snakehead (Channa gachua) around Gulf of Tonkin: Historical biogeography and pronounced effects of sea‐level changes

Geological events, landscape features, and climate fluctuations have shaped the distribution of genetic diversity and evolutionary history in freshwater fish, but little attention has been paid to that around the Gulf of Tonkin; therefore, we investigated the phylogeographic structure of the dwarf snakehead (Channa gachua) on Hainan Island and mainland China, as well as two populations in Vietnam. We attempted to elucidate the origins of freshwater fish in South Hainan by incorporating genetic data from DNA markers on both the mitochondrial cytochrome b gene (cyt b) and the nuclear recombination‐activating gene 1 (RAG‐1). Mitochondrial phylogenetic analysis identified two major lineages (lineages A and B), which may represent separate species. Divergence data suggested that C. gachua populations diverged between 0.516 and 2.376 myr. The divergence of the two cryptic species is congruent with sea‐level rise, which subsequently isolated Hainan from the mainland. During the Pleistocene glaciations, the entire region of the Gulf of Tonkin and the Qiongzhou Strait became part of the coastal plain of the Asian continent, which might have resulted in the current distribution patterns and dispersal routes of C. gachua populations. The formation of three sublineages in lineage A indicated that the Gulf of Tonkin was a geographical barrier between Hainan Island and mainland China but not between Vietnam and Hainan Island. The results of this study may help to elucidate the origins of freshwater fish in South Hainan and the phylogeographic structure of C. gachua.

Population genetic diversity and structure of Rhinogobius candidianus (Gobiidae) in Taiwan: Translocation and release

Rhinogobius candidianus is a freshwater goby distributed in north, northwest, west, and south Taiwan, but this species has been introduced to east Taiwan and became dominant. To investigate its native population genetic diversity and structure and evaluate the sources and diversity of translocated populations, the mitochondrial DNA control region and cytochrome b gene (1981 bp) from 220 specimens were analyzed. These results indicated that (1) the east populations originated from two sources in west Taiwan; (2) translocated populations exist in east Taiwan and south Taiwan; (3) many populations have likely been moved secondarily by human intervention; (4) the effective size of the populations had declined greatly; (5) within the native populations, the ancestral populations colonized Taiwan during the land bridge phase in the Pleistocene through north Taiwan; (6) the landform changes in Taiwan shaped the population structure; and (7) the landforms of the coastline during glaciation also shaped the native range. The low‐level genetic diversity, high population differentiation, and population decline greatly suggest the need for resource management and conservation interventions. Four clades ( α – δ ) should be managed as four distinct evolutionarily significant units, while the translocated populations should be managed as separate management units. Moreover, the translocated populations in east Taiwan should be evaluated and monitored carefully.
