    The population ecology and feeding biology of rocky shore crabs on the Cape Peninsula
    (1991) Le Roux, Peter James; Griffiths, Charles L
    This thesis consists of five chapters. One is a published paper, two are in paper format, and one is a thesis chapter. The thesis is preceded by a general introduction. The central theme of this work is the population ecology and feeding biology of rocky-shore crabs on the Cape Peninsula. The biology of three crabs is examined, namely, the ubiquitous brown shore-crab Cyclograpsus punctatus (M.Edw), the Cape rock-crab Plagusia chabrus (De Haan) and the invasive European shore-crab Carcinus maenas (L.). The possible impact of C. maenas upon the South African intertidal and local crabs in particular is also assessed.
