Assessment of the Genetic Diversity and Structure of the Korean Endemic Freshwater Fish <i>Microphysogobio longidorsalis</i> (Gobioninae) Using Microsatellite Markers: A First Glance from Population Genetics
<i>Microphysogobio longidorsalis</i> is endemic to South Korea and inhabits small areas of the Namhangang, Bukhangang, and Imjingang Rivers in the Hangang River water system. Endemic species usually are more vulnerable than species with a wide distribution. Notably, there is a lack of ba...

description | <i>Microphysogobio longidorsalis</i> is endemic to South Korea and inhabits small areas of the Namhangang, Bukhangang, and Imjingang Rivers in the Hangang River water system. Endemic species usually are more vulnerable than species with a wide distribution. Notably, there is a lack of basic conservation data for <i>M. longidorsalis</i>. We analyzed 19 microsatellite loci in six populations of <i>M. longidorsalis</i> in South Korea to characterize their population structure and genetic diversity. The genetic diversity of the microsatellites was 0.741–0.779, which is lower than that of other freshwater fishes. The pairwise genetic differentiation of microsatellite (<i>F</i><sub>ST</sub>) values ranged from 0.007 to 0.041, suggesting low genetic differentiation between the populations. The Jojongicheon stream population (CP) had an effective population size of <100. Therefore, conservation efforts are required to prevent inbreeding depression in <i>M. longidorsalis</i>. Discriminant analysis of principal components showed that the Hangang River water system would be a single management unit (MU). Our findings provide fundamental genetic insights for the formulation of conservation strategies for <i>M. longidorsalis</i>. |
