Abstract

We report the results of 2 types of field experiment done to examine the influence of the interaction between small-scale flow disruptions and chemical cues associated with conspecific individuals on the settlement of larvae of 2 congeneric barnacle species, Elminius modestus and E. covertus. One series of experiments (ridge experiments) examined the effects of the chemical component of barnacle presence and flow disruptions at the scale of settlement plates (<10 cm). Cyprids could contact surfaces containing chemical cues from conspecific adults on either ridged or flat plates. Settlement was greatest on plates with cues but was not affected by flow disruptions. The other experiment (mimic ..
