The ecology of the two populations of the intertidal pulmonate limpet, Siphonaria diemenensis.

The ecology of 2 populations of the limpet Siphonaria diemenensis were investigated on the rocky intertidal shore at Griffith Point, San Remo, Victoria from 1979 to 1981. One population was on flat rock in the high intertidal area (Zone 1) and the other population was on the boulders in the low intertidal area (Zone 2). In Zone 1, there were 3 sites (combined area of 3.146 m2) and 12 permanently marked 0.25m2 quadrats and in Zone 2, there were 2 sites (combined area of 1.291m2).

The population dynamics of the limpets were investigated by measuring shell lengths and dry weights of individuals in the 2 zones. Fences were used to enclose limpets or exclude limpets from areas of the substratum. Details of each experiment are described in the related records.
