The gastropod Cypohoma gibbosum is a principle predator of gorgonian corals on Caribbean coral reefs. However, little is known about how C. gibbosum populations are regulated or about how C. gibbosum affects gorgonian populations. We used 4 m cages to exclude large, predatory fishes and invertebrates from natural areas of a coral reef in the Florida Keys and assessed the role of predators in affecting C. gibbosum densities and their damage to gorgonians. After 10 months, C. gibbosum was up to…

The Role of Herbivorous Fishes in the Organization of a Caribbean Reef Community
TLDR
It is suggested that herbivorous fish grazing profoundly influences benthic species distributions and abundances within some tropical reef habitats and spatial variation in herbivory appears to be of fundamental importance in determining regional patterns of benthics community structure on tropical reefs.
RELATIVE ROLES OF HERBIVORY AND NUTRIENTS IN THE RECRUITMENT OF CORAL-REEF SEAWEEDS
TLDR
It is found that herbivory strongly reduced both density and growth of recruits for both species, whereas nutrient supply had minor effects on growth of Lobophora variegatarecruits and no detectable effects on Sargassum fissifoliumrecruits.
Large-scale associations between macroalgal cover and grazer biomass on mid-depth reefs in the Caribbean
TLDR
The abundance of macroalgae on lightly fished reefs may be a symptom of low coral cover in combination with the continuing absence of Diadema antillarum, a contributory factor in overfishing of grazing fishes.
Effects of herbivory and nutrients on the early colonization of crustose coralline and fleshy algae
TLDR
It is demonstrated that herbivory, in particular, can have a marked effect on the initial composition of the benthic community, even over a relatively short time span, and the inverse relationship between CCA and both fleshy algae and sediment has impli- cations for the recruitment of organisms with reliance on CCA.
Fouling and gastropod predation: consequences of grazing for a tropical octocoral
TLDR
Feeding by C. gibbosum increases fouling of gorgonians by exposing the axial skeleton and providing settling sites for fouling propagules, which suggests that the indirect effects of C. g~bbosum grazing could strongly affect the fitness of P. hornornalla and other gorg onians.
STRONG IMPACTS OF GRAZING AMPHIPODS ON THE ORGANIZATION OF A BENTHIC COMMUNITY
TLDR
Experimental results imply that grazing am- phipods, which are ubiquitous in marine vegetation but poorly understood ecologically, may play important roles in the organization of benthic communities, particularly where predation pressure is low.
Predictable spatial escapes from herbivory: how do these affect the evolution of herbivore resistance in tropical marine communities?

TLDR
Between-habitat differences in macrophyte consumption by herbivorous fishes were examined on three Caribbean and two Indian Ocean coral reefs, supporting the hypothesis that defenses against herbivores are costly in terms of fitness and are selected against in habitats with predictably low rates of herbivory.
Fishing, Trophic Cascades, and the Process of Grazing on Coral Reefs
TLDR
Increase in density of large parrotfishes caused a fourfold reduction in the cover of macroalgae, which highlights the potential importance of reserves for coral reef resilience.
Competition between macroalgae and corals: effects of herbivore exclusion and increased algal biomass on coral survivorship and growth
TLDR
The documented effects of increased algal biomass on coral growth and tissue mortality suggest a potential threat for the long-term survivorship and growth of corals in the Florida Reef Tract if present rates of algal growth and space utilization are maintained.
Algal propagule banks modify competition, consumer and resource control on Baltic rocky shores
TLDR
Recruitment inhibition by annual algae, which is driven by the abundance of annuals in the propagule bank, increasing nutrient levels, and declining consumer control, is suggested as a mechanistic explanation of the current decline of perennial algae in the Baltic Sea.
