The variation of Arginine kinase (Ark) genotype frequency among populations of Thais clavigera has been reported in previous study. However, the difference which is originated from self-seeding or differential selection after recruitment is not understood. To answer this question, the spatial (i.e. Shainsan, Taisi, Budai, and Chiku) and temporal (sell length: <15mm, 15-20mm, 20-30mm, 30-40mm, and >40mm; year: 2001 and 2003) variations of Ark allozyme were examined by starch gel electrophoresis. There was no significant difference in the ratio of Ark genotypes (ark63/63, ark63/100, ark100/100) in the size range of <15mm among Shainsan, Taisi and Chiku. The result indicated that the populations of T. clavigera is from the same recruitment. In the size range of 15-20mm, the frequency of ark63/63 increased from southern to northern populations, i.e. 0.21(Chiku) < 0.33(Budai) < 0.60(Taisi) < 0.66(Shainsan), respectively. It is proposed that the variation of Ark genotypes among populations is resulting from stress of temperature or dessication. A significant difference in the ratio of Ark genotypes was found in the population of Taisi with the size range of 30-40mm. Besides, the frequency of Ark genotypes among populations was not related to the degree of imposex.
