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).

Parapatric speciation Neighboring populations become distinct species while maintaining contact along a common border, hybrids formed along border, weak, low fitness level. They rode the high seas for a month before colonizing the Caribbean island, Anguilla. 44 Citations; 90 Downloads; Part of the Proceedings in Life Sciences book series (LIFE SCIENCES) Abstract. Recent advances in molecular genetic techniques have enabled researchers to pinpoint individual loci and mutations contributing to phenotypes that are relevant to speciation. Long-term studies of the ecological genetics and behavior of the Hawaiian Drosophila have demonstrated that sexual selection can generate rapid speciation (Carson and Kaneshiro 1976; Carson 1982). 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.

Drosophila, females, incipient speciation, males, sexual selection, Hawaii Abstract: We conducted sexual selection experiments to produce strains with high and low mating discrimination in females of laboratory strains of Hawaiian Drosophila, D. silvestris, then examined secondary sexual traits of these two lines, and compared them with that of standard line.
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. 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. Genome size expansions have occurred independently multiple times among Hawaiian Drosophila lineages, and have resulted in an …
These few individuals were perhaps the first of their species, Iguana iguana, to reach the island. In the summer of 1995, at least 15 iguanas survived Hurricane Marilyn on a raft of uprooted trees.
