| Abstract;Genetic diversity and differentiation of Far Eastern cyprinids, nine populations from six river basins of Rhynchocypris perenurus sachalinensis from Hokkaido, Japan, and six populations from six river basins of R. p. mantchuricus from Russia, were analyzed based on allelic constitution of 18 allozyme-coding loci. Observed genetic differentiation supported the subspecific taxonomy of these subspecies, alleles being clearly displaced in two to four loci between them. Genetic diversity of R. p. mantchuricus was larger than that of R. p. sachalinensis, indicating larger effective population size in the former species. A critical reduction of genetic diversity was observed in four R. p. sachalinensis populations from man-made river-bed ponds of the Shibetsu River basin. (author abst.) |
