ABSTRACT A survey of biochemical polymorphism among glucose- and non-glucose-metabolizing enzymes was carried out on the June 1973 collection from the South Amherst, Mass. Drosophila melanogaster natural population. Polymorphic levels are among the highest recorded for this species; polymorphism among glucose-metabolizing enzymes did not differ significantly from that among non-glucose-metabolizing enzymes. Two loci, G6Pd on the × and Est-6 on the 3rd chromosome, displayed significant excesses of heterozygotes. Adh on the 2nd and Idh, Odh and Ao on the 3rd chromosome showed significant heterozygote deficiencies. Idh is ten map units to the left of Est-6, Odh twelve map units to the right and Ao is seven units beyond Odh. Temperatures in the two-week June period prior to collection were exceedingly variable. Daily high/low ranged between 76°/40° and 97°/65°F. These results support the findings of Frydenberg and Simonsen (1973) that in some populations glucose-metabolizing enzymes tend to be as polymorphic as non-glucose-metabolizing ones. They also add to the evidence obtained from other plant and animal populations that increased biochemical polymorphism is associated with more variable and/or colder climates. The increase may in part be due to increased polymorphism among glucose-metabolizing enzymes. Comparisons utilizing published data on other D. melanogaster populations and on D. robusta indicate a clinal increase in heterozygosity among glucose-metabolizing enzymes as one moves northward.

Coreoleuciscus splendidus was first reported as a monotypic species. Recent morphological and genetic studies have revealed that the species is represented by two disjunct and distinct lineages. The two lineages of C. splendidus include populations inhabiting the Han and Geum rivers in the East Korea Subdistrict and populations inhabiting the Seomjin and Nakdong rivers in the South Korea Subdistrict. In this study, significant differences were found between these two independent lineages through a high degree of genetic divergence in the mitochondrial cytochrome c oxidase subunit I gene as well as conspicuous morphological differences in body coloration and shapes of black stripes on dorsal, anal and caudal fin rays. These morphological and genetic differences provide supporting evidence that the populations in the South Korea Subdistrict represent a new species, Coreoleuciscus aeruginos.
