Abstract
Gametophytes from lower intertidal populations of the South African rhodophyte Gigartina radula, collected from sites subjected to different conditions of wave exposure, were compared with respect to various morphological, physiological and population attributes. A multivariate analysis of 13 variables revealed that variation in most parameters does not correlate directly with the wave exposure gradient. A clear pattern of response is revealed that suggests that environmental stresses occur at both the exposed and the sheltered sites although they are more extreme at the exposed sites. A number of important variables, notably photosynthetic production, showed maximum values in plants from semi-exposed sites.
