| The present study was undertaken to investigate the observation that dolorite and shale shores in the Transkei tended to have less algal cover and to support more grazers than sandstone shores. The structure of rocky intertidal communities is determined by the interaction of a number of biotic and abiotic factors. The chemical and physical nature of the substratum has been shown to have an influence on colonization, but few studies have attempted to quantify experimentally the differences in succession observed on different substrata. Rock tiles (10 x 10 cm) cut from shale, dolorite and sandstone were placed on three shores, each dominated by one of the rock types, and monitored photographically for 18 months. Within each type two treatments consisting of... |
