AbstractLarval settlement of the barnacle Balanus amphitrite Darwin (Cirripedia, Balanidae) is influenced by natural biofilms. In previous work by others, discriminatory settlement of aged cyprids has been observed in response to biofilms of different age. This study extends prior work by considering the effect of the age of cyprids on the outcome of settlement assays. Settlement was investigated with 0-day-old (newly metamorphosed) and 5-day-old cyprids. Biofilms under investigation were developed in the field for periods of 5 d and 1 month, and were subsequently included in laboratory settlement assays with a choice between a filmed and an unfilmed substratum. The bioassay was modified from the conventional horizontal dish design in order to generate a low water surface-to-volume ratio, which served to suppress larval entrapment in an organic layer on the water surface. Irrespective of cyprid age, a clear discrimination between a filmed and an unfilmed substrata was observed, and the preference for filmed or unfilmed substratum was dependent on the age of the cyprids. Settlement of 0-day-old cyprids was inhibited by a biofilmed substratum whereas induction occurred with aged cyprids. This pattern of settlement was independent of biofilm age. Bacterial abundance on unfilmed substrata in treatments and controls was significantly lower than that on biofilmed surfaces, confirming that bacterial contamination did not change the qualitative option during the assay.
