Genetic variation and gene flow of broadcast spawning and planula brooding coral, Goniastrea aspera (Scleractinia) in the Ryukyu Archipelago, southern Japan.

Zoological science - 1 Aug 2003

Nishikawa Akira, Sakai Kazuhiko

Abstract excerpt

The scleractinian coral Goniastrea aspera (Verrill) undergoes both broadcast spawning and planulae brooding in the Ryukyu Archipelago of southern Japan. Genetic variation and gene flow in G. aspera were studied using allozyme electrophoresis. We tested the hypothesis that gene flow is determined by the competency period of the planulae. We also assessed the relative contributions of sexual and asexual...
