The major agents of biological destruction of coral reefs can be divided into grazers, etchers and borers. Each of these groups is reviewed on a world wide basis, together with the mechanisms by which they destroy the coral substrate. Rates of bioerosion attributed to major agents of grazers, etchers and borers are given, together with limitations of some of the measurements. Recent work is highlighting the variability in rates of bioerosion both over time and space. Factors which may be… 
Although the review concentrates mainly on present day reefs, some attempt is made to consider the impact of bioerosion on older reefs.
Bioerosion of reef-building crustose coralline algae by endolithic invertebrates in an upwelling-influenced reef
The aim of this study was to examine the percentage and rates of internal bioerosion by macroborer invertebrates in two dominant CCA species and to explore whether the oceanographic variability influences the nature ofBioerosion in coral reefs of the Tayrona Natural National Park (Colombia).
Bioerosion on modern reefs: impacts and responses under changing ecological and environmental conditions
Biological erosion (bioerosion) is a key ecological process on coral reefs. It occurs though the grazing activities of specific fish and sea urchin species, and as a result of the colonisation of
The Ecology of Coral Reef Fishes Modified in May 2003 for QUEST
One of the first things that catches the attention of a diver entering the warm waters of the coral reef is the phenomenal diversity, abundance, and beauty of fishes swimming before them. While all
Coral Reef Bioerosion in the Eastern Tropical Pacific
Bioerosion, the weakening and erosion of hard substrates by boring, etching, and grazing organisms, is a major structuring force on coral reefs of the Eastern Tropical Pacific (ETP). Bioerosional
Reef bioerosion : agents and processes
Coral reef maintenance depends on the balance between constructive and destructive forces. Constructive forces are mainly calcification and growth of corals and encrusting coralline algae.
Sponge bioerosion and habitat degradation on Indonesian coral reefs
Coral reefs are among the most diverse ecosystems on the planet, yet they are also sensitive to anthropogenic disturbances that can degrade these systems. On many degraded reefs, large increases in

A spatially explicit simulation model of a Caribbean coral reef is used to examine the ecosystem requirements for grazing which is primarily conducted by parrotfishes (Scaridae) and suggests that failure to manage scarid populations outside reserves will have a profoundly negative impact on the functioning of the reserve system and status of non-reserve reefs.
The ecosystem roles of parrotfishes on tropical reefs
Parrotfish are ubiquitous on tropical reefs worldwide, yet there is strong spatial structuring in the taxonomic and functional composition of the group, which has been shaped by their biogeographic history, the productivity of their environment, and the habitat requirements of individual taxa.

The greatest diversity of both species and community types was found on reefs near the middle of the continental shelf, while the oceanic atolls and nearshore silt-affected reefs are almost equally depauperate.
Patterns in the Distribution of Coral Communities Across the Central Great Barrier Reef
This study describes seventeen assemblages of corals which occupy the major habitat types found in and near the central Great Barrier Reef, and produces a scheme depicting apparent ordering of coral communities in relation to hydrodynamic forces, illumination, and position on the onshore-offshore transect.
Do sponges help hold coral reefs together?
The growth and form of coral reefs is the result of a complex balance between rates of carbonate accretion and carbonate loss. Reef organisms have traditionally been classified, with respect to their
Transport of Calcareous Fragments by Reef Fishes
It was found that browsing omnivorous reef fishes which rely, in part, on a plant diet ingested and redeposited at least 2300 kg of sand, coral scrapings, algal fragments, and other calcareous materials which pass through the intestines of reef fishes.
The distribution and abundance of cryptofauna at Lizard Island, Great Barrier Reef
A series of replicate samples of dead coral reef habitats was collected across Yonge Reef on the outer and inner reef (back reef) and on fringing reefs around Lizard Island. Five categories of

Experimental Studies on the Ecology of Intertidal Environments at Heron Island. I. Exclusion of Fish from Beach Rock.
The zonation of dominant organisms on the beach rock at Heron Island was reinvestigated and it was confirmed that browsing fish are the most important single controlling factor.

Ecological Aspects of Some Coral-Boring Gastropods and Bivalves of the Northwestern Red Sea
More than 17 molluscan species were obtained from burrows in coral substrata at Al-Ghardaga on the Red Sea coast, six of which in particular bore into livingcolonies, including Lithophaga laevigata, which bore mainly mechanically by the rocking movements of the shell.
