Abstract

The AFLP (amplified fragment length polymorphism) technique was used to analyze and compare the genetic diversity of Tachypleus tridentatus from three south-eastern coastal sites of China (Pingtan, Hong Kong and Beihai). Eight pairs of primers generated 361 loci, including 285 polymorphic loci. The ratio of polymorphic loci was 96. 97%. Nei's genetic diversity index was 0. 420 8 and the Shannon information index was 0. 607 5, both of which were higher than that reported for many other arthropods. These results show that the genetic diversity detected was mainly caused by individual differences within a population. Genetic distance showed that the rational division of the three geographic populations of T. tridentatus along the south-eastern coast of China was not significant, in which the genetic distance was not proportional to the geographic distance. All three horseshoe crab populations may belong to a large group, and had a high degree of genetic similarity. The high level of genetic diversity obtained from the present AFLP analysis may be due to the large effective population size of the species in Chinese waters. © 2011 Chinese Society for Oceanology and Limnology, Science Press and Springer Berlin Heidelberg.
