The timing of larval release in colonial ascidians
Caribbean Marine Studies
Date of Publication
Reports on larval release times for six Caribbean species of ascidians and compares with other records from the literature. Identifies four strategies of release - larval release throughout the day, only in the morning, only at sunrise, and around the solar meridian. Contends that early morning release provides maximum opportunity for dispersal, but midday release is probably related to the need to locate a settlement site that is shielded from the harshest period of solar radiation. Concludes, contrary to other authors, that midday release is designed to protect the juvenile ascidian rather than algal symbionts living in both larva and adult of some species....
