Description
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.
