“…Because N. hainanensis is strictly freshwater fish of small body size, with a benthic habit, and presumably lacks planktonic eggs or a larval stage ( Iwata et al 2001 ; Iwata 2011 ), its capacity for migration may be limited. Similar phenomenon was also found in Perccottus glenii Dybowski, 1877 in northeastern China ( Zhang et al 2021 ), Channa gachua around Beibu Gulf ( Wang et al 2021 ), and Tanichthys albonubes in southern China and northern Vietnam ( Zhao et al 2018 ). In contrast, populations of Hemiculter leucisculus (Basilewsky, 1855) in Guangdong, in Guangxi, and on Hainan Island ( Chen et al 2017 ) do not show evident differentiation.…”

Study of divergence of freshwater fish populations between island and adjacent mainland areas can shed light on the phylogeographical relationships of these regions. Neodontobutis hainanensis is a freshwater fish species restricted to Hainan Island and in Guangdong and Guangxi provinces in the southern mainland China. We examine the phylogenetic relationship and population structure of N. hainanensis based on 3,176 nuclear loci using a gene-capture method. STRUCTURE analysis and principal coordinate analyses (PCA) indicate that populations from Guangdong, Guangxi and Hainan are each distinct, except that some individuals of the Guangdong population share minor genetic components with individuals of the Guangxi population. In the concatenated gene tree, the Hainan population is grouped with the Guangdong population, but the coalescent tree groups the Hainan population as the sister to the Guangxi population. Finally, coalescent simulations confirmed the divergence pattern supported by the coalescent tree and revealed a one-way introgression from the Guangxi population to the Guangdong population, which can explain the discordant results supported by the concatenated and coalescent phylogenetic analyses. Due to recent decline of N. hainanensis populations and the genetic patterns in this species, as revealed in this study, the populations in the three areas should be treated as separate conservation units.

Based on the polymorphism of multilocus DNA markers (inter simple sequence repeat (ISSR)), we assessed the level of genetic variability and differentiation of populations of two invasive species, the Amur sleeper (Percottus glenii) and its specific parasite, Nippotaenia mogurndae, from five reservoirs in the acquired part of the range, the Irtysh River basin, Western Siberia. We revealed a high genetic polymorphism of neutral DNA markers in P. glenii. In general, the proportion of polymorphic loci was 92%, the average heterozygosity was 0.32. These parameters were lower in particular populations of P. glenii and varied within 53–74% and 0.20–0.23, respectively. The interpopulation component accounted for approximately 35% of the variability (GST = 0.35). In N. mogurndae, polymorphism was 73.7%, heterozygosity was 0.18, varying within 18–45% and 0.06–0.15, depending on the population. The level of genetic differentiation of N. mogurndae (GST = 0.38) was similar to that of P. glenii, which indicates that the processes of genetic differentiation of the parasite and the host are synchronous. Polymorphism and genetic distances of the parasite were lower than those of the host. The population genetic structure of P. glenii was partially consistent with the structure of the hydrographic network, in contrast to N. mogurndae. The data obtained indicate that during dispersal, no significant reduction in genetic polymorphism occurred in the Amur sleeper, and over several decades a population-genetic structure characteristic of this species in the native range was formed in the acquired part of the range.
