Intertidal grazing gastropods play an important role in structuring rocky shore communities. For many years the main food resource to these animals was considered to be epilithic biofilms. This study shows that macroalgae are a more important component of gastropod diets than was previously appreciated and that biofilms contribute surprisingly little to their trophic ecology. Stable carbon and nitrogen isotope analyses were used to examine grazer diets, comparing sources of assimilated carbon and nitrogen in gastropod tissues between moderately wave exposed and sheltered sites in northern and southern Britain. Carbon isotope (δ13C) values of biofilms were considerably lower than those of grazing gastropods at all of the sites examined. The δ13C values of grazer tissues were much more closely related to the carbon isotope values of macroalgae, demonstrating the importance of these foods to intertidal grazing gastropods. Nitrogen isotope values were consistent with this conclusion and reflected differences in the source pools of nitrogen between the two sampling regions. Gut contents analysis was used to directly quantify the diet of the intertidal limpet Patella vulgata in detail. Biofilms and corticated/leathery macroalgae contributed most substantially to patterns of ingested materials and limpet diet was strongly influenced by food availability. Animals from sheltered and northern sites consumed more macroalgae whilst animals from southern sites consumed more biofilm. Stable isotope data from mensurative experiments confirmed the important role of food availability in controlling limpet diets. Data from manipulative caging experiments provided further evidence for this effect and also showed that species identity and interspecific competition influence trophic ecology in intertidal gastropods. Patella depressa isotope values remained different from those of Patella vulgata irrespective of food availability and competition in experimental cages. Stable isotope ratios of Patella vulgata and Littorina littorea, distinct in single species cages, converged towards a common value when held together.

Seagrass is an underwater flowering plant that thrives in clear, sheltered, coastal waters around the world. As well as providing habitat for the marine fauna, seagrass meadows play an important role in the processes and resources of near-shore ecosystems. Coastal degradation of seagrass is prevalent along the metropolitan beaches of Adelaide, a problem common to settled coastal areas around the world, and although evidence from the literature suggests that loss of seagrass beds adversely affects the abundance of some coastal fish species, no quantification of the effect has been attempted. / Thesis (PhDMathematics)--University of South Australia, 2003.

Artificial substrata were employed at sites on the east and west coasts of Scotland, in such a manner as to model the habitat found on the undersides of boulders on the shore. Panel treatments were devised to examine the effects of substratum 'age' and larval availability, and the presence or absence of varying densities of herbivorous molluscan grazers on the development of the epifaunal assemblages. The importance of inter- and intraspecific competition in structuring the bryozoan component of the assemblage was also examined. A necessary pre-requisite for the settlement of many marine invertebrate larvae may be the development of a microfouling film, the nature of which may vary depending on its 'age', with corresponding effects on the 'attractiveness', or otherwise, to potentially settling larvae. The lowest numbers of recruits were frequently recorded on the 'youngest' panels, and greater numbers generally occurred on panels immersed for longer periods. Also of overriding significance, however, was the seasonal variability in larval availability. The assemblages were characterized by high levels of post-settlement mortality. The outcomes of the overgrowth interactions between 18 species of encrusting bryozoans were highly variable and complex, each species of an interacting pair won some encounters, and neither consistently overgrew the other. Therefore, the pattern of competitive abilities was neither entirely intransitive or transitive. Variations in outcome were found to be at least partially attributable to differences in the encounter angle between colonies. The competitive ability of a species also varied among sites and between years. The herbivorous grazing gastropod Gibbula cineraria was found to have a markedly deleterious effect on the developing assemblages. Furthermore, individuals and colonies of the epifaunal species were apparently unable to achieve an 'escape-in-size' under the experimental conditions employed.
