Man as a Component of the Littoral Predator Spectrum: A Conceptual Overview

  • P. A. R. Hockey
Part of the Ecological Studies book series (ECOLSTUD, volume 103)

Abstract

Man functions both as a predator and as a mega-herbivore in intertidal and shallow subtidal ecosystems. Here, I concentrate on providing a conceptual synthesis and overview of his role as a predator; man’s role as a mega-herbivore being detailed elsewhere (Santelices and Griffiths, this vol). Predation occurs when one organism kills another for food (Taylor 1984). This definition includes some forms of herbivory, such as the grazing of algal sporelings, but excludes parasitism. In littoral ecosystems, any collecting of algae by man which involves removal of the entire plant, or enough of the plant such that it subsequently dies, can therefore be classified as predation.
