If the faunas were originally established by rare transport events, can island populations subsequently maintain themselves with local larval retention? Plectroglyphidodon imparipennis is a small omnivore com- mon on shallow reefs. The species has a very broad tropical distribution from East Africa to Hawaii, the Line, Marquesan, and Pitcairn Islands; north to the Ryuku and Bonin Islands; south to New Caledonia and Rapa; throughout Micronesia and the Indonesian archipelago (10). The color pattern of this spe- cies varies geographically. Settlement stage larvae were collected by "nightlighting"; a bright light was suspended in the water near the surface. Larvae attracted to the light were caught in a handnet and then pre- served in 90% ethanol. Hawaiian larvae were collected from 20 February 1982 to 30 June 1982 within 5 nm of the coastline from Kailua-Kona to Keahou Bay, Hawaii. Johnston Atoll lar- vae were collected on 5 September 1983, also within 5 nm of reefs. Larval age was determined from otolith ring counts
