Intertidal and Subtidal Filter-Feeders in Southern Africa,enson 1972). Physical factors, such as temperature and desiccation, tend to set upper limits on the intertidal distribution of organisms, whereas biological factors, such as competition for food and space, as well as predators, determine the distribution and abundance of populations in the lower int

Intertidal and Subtidal Grazers, Removal of grazers often leads to a dramatic development of seaweed beds. In this chapter we begin by tracing the effects that human exploitation has on populations of grazers and on algae. These effects are usually obvious and easy to predict. There are, however, indirect effects that can arise fr

Biological Options for the Management of the Exploitation of Intertidal and Subtidal Resources,ecause the effects of human exploitation differ qualitatively from those of natural predators. For example, Fig. 7.1 summarizes the interplay between man and other organisms in the intertidal zone of islands off the west coast of southern Africa. Four sets of natural biological interactions have bee

Similar impressive evidence, going back to at least 100000 years, exists for prehistoric man‘s consumption of intertidal animals a
