Temporal and Spatial Variations of Arginine Kinase Allozyme Among Populations of Thais clavigera From the West Coasts of Taiwan

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.
