Analysis of genetic differentiation and population structure of the Korean-peninsula-endemic genus, Semisulcospira, using mitochondrial markers

The genus Semisulcospira is an economically and ecologically valuable freshwater resource. Among the species, coreana, forticosta tegulata are endemic to Korean peninsula gottschei widespread in Asia. Therefore, maintenance conservation of wild populations these snails important. We investigated genetic diversity population structure based on mitochondrial cytochrome c oxidase subunit I (COI), NADH dehydrogenase 4 (ND4), combined DNA (COI + ND4) sequences. All four species various makers showed a high level haplotype low nucleotide diversity. In addition, Fu’s Fs Tajima’s D neutrality tests were performed assess variation size among populations. Neutrality yielded negative values, except for with one haplotype. minimum spanning network indicated common S. gottschei, whereas had rare Also, differences gene flows between assessed by analysis molecular variance using pairwise fixation index. Our findings provided insight into degree preservation species’ could be utilized enhance management species.
