Kaneshiro t has long been recognized that the Hawaiian Islands possess one of the most remarkable insect fau- nas on Earth and are indeed the ideal natural laboratories for the study of the processes of speciation and evolu-tion (Hardy and Kaneshiro 1981).
About 100 species of Hawaiian Drosophila, such as the male D. nigribasis shown here, have large patterned wings and are known as picture-winged Drosophila. For example, a species known as Drosophila silvestris occupies several discrete patches of forest on the Big Island (see Figures 12a … These few individuals were perhaps the first of their species, Iguana iguana, to reach the island. Speciation in action? ELYSSE M. CRADDOCK2 AND MICHAEL P. KAMBYSELLIS3 ABSTRACT: The entomologist R. C. L. Perkins pioneered observations ofbreeding site ecology for the endemic Hawaiian Drosophilidae, a renowned group of flies that has undergone explosive speciation and adaptive … The Hawaiian Drosophila fauna contains many such species; because the fauna contains species pairs that differ primarily in their sexual behavior (Table 1), there is a reasonable expectation that the associations between sexual selection and speciation can be teased apart. Ex. Karyotypic stability and speciation in Hawaiian Drosophila H L Carson , F E Clayton , H D Stalker Proceedings of the National Academy of Sciences May 1967, 57 (5) 1280-1285; DOI: 10.1073/pnas.57.5.1280 Recent advances in molecular genetic techniques have enabled researchers to pinpoint individual loci and mutations contributing to phenotypes that are relevant to speciation. This paper reports genome sizes of one Hawaiian Scaptomyza and 16 endemic Hawaiian Drosophila species that include five members of the antopocerus species group, one member of the modified mouthpart group, and ten members of the picture wing clade. In the summer of 1995, at least 15 iguanas survived Hurricane Marilyn on a raft of uprooted trees.
