| Abstract: | Experiments using cages at four shore levels were carried out to determine the part played by the feeding of the gastropods Neothais scalaris and Lepsiella scobina on the zonation of three species of intertidal barnacles: Chamaesipho brunnea, C. columna, and Epopella plicata. The lower limit of the two larger barnacle species was determined by predation, but C. columna was affected only in the absence of the other two barnacles. |
