Abstract: | Chasmagnathus convexus is a mudflat crab that is distributed throughout East Asia. However, most populations of this species in Korea are endangered
due to continuing seashore developments and habitat fragmentations. In this study, we isolated and characterized nine microsatellite
loci from C. convexus. The number of alleles per locus ranged from 3 to 23. The expected heterozygosities ranged from 0.145 to 0.974 and the observed
heterozygosities ranged from 0.150 to 0.947. Cross-species amplifications for 10 other Varunid crab species were performed.
These microsatellite markers could be useful for planning conservation strategies for C. convexus and related species. |
