Abstract

Distributional patterns of the pulmonate limpet, Siphonaria pectinata, were studied at an intertidal rock outcrop near Boca Raton, Florida from August to November 1982. The locations of all limpets (167,368) in a 272m2 region of the outcrop were analyzed statistically including the use of computer-aided trend surface analysis. Limpet distribution was restricted seawardly by algal mats near mean sea level (MSL) and by the lack of tidal wetting at approximately 2.0 ft above MSL. The highest concentrations of ~. pectinata occurred from 0-1.5 ft elevation, on the seaward side of the outcrop. gregarious clumping. The distribution was highly clumped, with homesite selection contributing to local Limpet homing experiments were performed on isolated rocks in the Boca Raton Inlet. Siphonaria pectinata is capable of homing by means of topographic memory systems alone. External cues, chemical cues and/or dead-reckoning systems are not required for homing but may contribute to a hierarchy of homing stimuli.
