Dynamics of a temperature-related coral disease outbreak

Jones, RJ, Bowyer, J, Hoegh-Guldberg, O, Blackall, LL

During the austral summer of 2001/2002, a coral epizootic occurred almost simultaneously with a bleaching event on the fringing reefs of Magnetic Island (Great Barrier Reef region), Australia. This...

Coral bleaching following wintry weather

Hoegh-Guldberg, O, Fine, M, Skirving, W, Johnstone, R, Dove, S, Strong, A

Extensive coral bleaching Occurred intertidally in early August 2003 in the Capricorn Bunker group (Wistari Reef, Heron and One Tree Islands; Southern Great Barrier Reef). The affected intertidal...

Closely related Symbiodinium spp. differ in relative dominance in coral reef host communities across environmental, latitudinal and biogeographic gradients

LaJeunesse, TC, Bhagooli, R, Hidaka, M, DeVantier, L, Done, T, Schmidt, GW, ...

The diversity and community structures of symbiotic dinoflagellates are described from reef invertebrates in southern and central provinces of the Great Barrier Reef (GBR), Australia, and Zamami...

Tolerance of endolithic algae to elevated temperature and light in the coral Montipora monasteriata from the southern Great Barrier Reef

Fine, M, Meroz-Fine, E, Hoegh-Guldberg, O

Photosynthetic endolithic algae and cyanobacteria live within the skeletons of many scleractinians. Under normal conditions, less than 5% of the photosynthetically active radiation (PAR) reaches the...

Low coral cover in a high-CO2 world

Hoegh-Guldberg, O

Coral reefs generally exist within a relatively narrow band of temperatures, light, and seawater aragonite saturation states. The growth of coral reefs is minimal or nonexistent outside this...

The effect of temperature on the size and population density of dinoflagellates in larvae of the reef coral Porites astreoides

Edmunds, PJ, Gates, RD, Leggat, W, Hoegh-Guldberg, O, Allen-Requa, L

Pre-settlement events play an important role in determining larval success in marine invertebrates with bentho-pelagic life histories, yet the consequences of these events typically are not well...

Global assessment of coral bleaching and required rates of adaptation under climate change

Donner, SD, Skirving, WJ, Little, CM, Oppenheimer, M, Hoegh-Guldberg, O

Elevated ocean temperatures can cause coral bleaching, the loss of colour from reef-building corals because of a breakdown of the symbiosis with the dinoflagellate Symbiodinium. Recent studies have...

Response of holosymbiont pigments from the scleractinian coral Montipora monasteriata to short-term heat stress

Dove, S, Ortiz, JC, Enriquez, S, Fine, M, Fisher, P, Iglesias-Prieto, R, ...

Heating the scleractinian coral, Montipora monasteriata (Forskal 1775) to 32 degrees C under < 650 mu mol quanta m(-2) s(-1) led to bleaching in the form of a reduction in Peridinin, xanthophyll...

Fluorescence in situ hybridization and spectral imaging of coral-associated bacterial communities

Ainsworth, TD, Fine, M, Blackall, LL, Hoegh-Guldberg, O

Microbial communities play important roles in the functioning of coral reef communities. However, extensive autofluorescence of coral tissues and endosymbionts limits the application of standard...

Spatial patterns of aerobic and anaerobic mineralization rates and oxygen penetration dynamics in coral reef sediments

Werner, U, Bird, P, Wild, C, Ferdelman, T, Polerecky, L, Eickert, G, ...

Oxygen consumption rates (OCR), aerobic mineralization and sulfate reduction rates (SRR) were studied in the permeable carbonate reef sediments of Heron Reef, Australia. We selected 4 stations with...
