| Abstract: | Summary The influence of juvenile hormone (JH)-active chemicals on the settlement and metamorphosis of metatrochophore larvae of the polychaete annelid Capitella sp. I of the Capitella complex has been investigated. These studies demonstrate that JH-active chemicals are able to induce settlement and metamorphosis of Capitella larvae, and that these effects may possibly be mediated by protein kinase C induction. Evidence for the presence of JH-active compounds in marine sediments is also presented, suggesting that these chemicals may serve a natural role as chemical cues for settlement and metamorphosis for Capitella larvae in the marine environment. |
