Subtropical Benthos Vary With Reef Type, Depth, And Grazing Intensity, Kara R. Wall

USF Tampa Graduate Theses and Dissertations

Marine epibenthic communities are influenced by both pre- and post-recruitment processes. For instance, the larval supply and cues that influence settlement (pre-recruitment), as well as the growth and mortality of individuals (post-recruitment), may differ across reef type and depth. Determining the relative influence of these processes is important to understanding how epibenthic communities can develop in a region. Using both a recruitment experiment that controlled grazing by urchins and in situ photographic surveys of epibenthic communities, this study examined the recruitment and composition of epibenthos on natural limestone and artificial reefs in the eastern Gulf of Mexico (eGOM). In the …
