| Climate change is one of the greatest threats to the long-term maintenance of coral-dominated tropical ecosystems, and has received considerable attention over the past two decades. Coral bleaching and associated mortality events, which are predicted to become more frequent and intense, can alter the balance of different elements that are responsible for coral reef growth and maintenance. The geomorphic impacts of coral mass mortality have received relatively little attention, particularly questions concerning temporal recovery of reef carbonate production and the factors that promote resilience of reef growth potential. Here, we track the biological carbonate budgets of inner Seychelles reefs from 1994 to 2014, spanning the 1998 global bleaching event... |

| Bioerosion by grazing and boring organisms is one of the major destructive forces operating on reef. The aim of this study was to estimate the intensity of internal bioerosion by both microflora and fauna of Acropora, a branching scleractinian, on the reef flat at La Saline (Reunion, Indian Ocean). Internal bioerosion was estimated at two sites, varying in degrees of eutrophication. At each site, dead Acropora subjected to heavy grazing or covered by algal turf were examined. Acropora formosa is subjected to high bioerosion due to its high porosity and its branching form, which facilitates colonisation by boring organisms. Three endolithic microflora species, Plectonema terebrans, Mastigocoleus testarum and Ostreobium queckettii colonised the branches. The... |

| Parrotfishes (Perciformes: Scaridae) represent a critical functional group on coral reefs because their intense herbivory activity helps in avoiding coral overgrowth by algae. Although feeding preferentially on algae and detritus, some parrotfish species also consume live corals, leading to detrimental effects that may offset the benefits of removing competitive seaweeds. Parrotfish species differ markedly in terms of jaw morphology, foraging activity and extent of substratum excavation, and are typically divided into three functional groups: browsers, scrapers and excavators. The recognition of species within each functional group helps to understand their relative effects in terms of bioerosion, coral fitness and survival, habitat alteration and... |

| ABSTRACT Dead Acropora palmata branches colonized by the excavating sponge Cliona tenuis are prone to dislodgement, breakage, and translocation during heavy surge and swell from storms or hurricanes, favoring the dispersion of this sponge. At Islas del Rosario (Colombia, Caribbean), adult C. tenuis carried by A. palmata fragments that fell onto live massive corals were able to colonize the new coral, subsequently killing live tissue of the newly invaded coral. Corals that recruited onto fallen A. palmata branches overgrown with adult C. tenuis were also invaded once the sponge reached their base. To determine if the incidence of this phenomenon has increased since 2002 when it was first documented, the mode and prevalence of colonization of corals by C.... |

| Abstract: We describe the first occurrence of biogenic traces made by mammals within an iron formation cave located in the Serra da Ferrugem Ridge, in Southeastern Brazil. These bioerosions are tooth traces produced in boulders, walls and floor within the cave. The traces occur as sets of two or more grooves, which are highly variable in size. The grooves were compared to tooth traces artificially produced by imprinting the incisors of different mammal species collected in the cave region on soft clay. Among those, the following taxa are potential tracemakers: Akodon sp., Oligoryzomys sp., Necromys lasiurus, Rhipidomys mastacalis, Oecomys gr. concolor, Trinomys moojeni, and Hydrochoerus hydrochaeris. The age of the traces is unknown; therefore, any... |

| Historically, coral reefs have been subjected to a range of disturbances including major sedimentary events from flooded rivers (Robertson & Lee Long, 1990), storm events and changes related to long-term patterns such as El Niño (Glynn, 1985). Reef ecologists have accumulated a great deal of evidence implicating disturbance as a major influence on reef ecology (Connell, 1978). Increasing global temperatures, eutrophication in coastal areas and the physical damage that is becoming so widespread is potentially reducing the reefs intrinsic ability to cope with such perturbations. Primary production on a reef is largely dependent on a variety of algae including the symbiotic algae living in hard corals (zooxanthellae). The level of production that any of... |
