Abstract
The South African abalone Haliotis midae is a commercially exploited species that is seriously threatened by overfishing and poaching. This not only affects the species itself but also the integrity and functionng of the ecosystem through associated changes in community structure. I assessed the influence of abalone on the ecosystem by a combination of (a) dietary studies, (b) comparisons of communities living on shell versus surrounding rock substratum, and (c) removal experiments using field exclusion/inclusion plots.
