Coral Reefs, the Journal of the International Society for Reef Studies, presents multidisciplinary literature across the broad fields of reef studies, publishing analytical and theoretical papers on both modern and ancient reefs. These encourage the search for theories about reef structure and dynamics, and the use of experimentation, modeling, quantification and the applied sciences.

Coverage includes such subject areas as population dynamics; community ecology of reef organisms; energy and nutrient flows; biogeochemical cycles; physiology of calcification; reef responses to natural and anthropogenic influences; stress markers in reef organisms; behavioural ecology; sedimentology; diagenesis; reef structure and morphology; evolutionary ecology of the reef biota; palaeoceanography of coral reefs and coral islands; reef management and its underlying disciplines; molecular biology and genetics of coral; aetiology of disease in reef-related organisms; reef responses to global change, and more.

Abstract: It is well established that different coral species have different susceptibilities to thermal stress, yet it is less clear which biological or physical mechanisms allow some corals to resist thermal stress, whereas other corals bleach and die. Although the type of symbiont is clearly of fundamental importance, many aspects of coral bleaching cannot be explained solely by differences in symbionts amongst coral species. Here, I use the CO2 (sink) limitation model of coral bleaching to repose various host traits believed to influence thermal tolerance (e.g. metabolic rates, colony tissue thickness, skeletal growth form, mucus production rates, tissue concentration of fluorescent pigments and heterotrophic feedings capacity) in terms of an integrated strategy to reduce the likelihood of CO2 limitation around its intracellular photosymbionts. Contrasting observational data for the skeletal vital effect on oxygen isotope composition (δ18O) partitions two alternate evolutionary strategies. The first strategy is heavily reliant on a sea water supply chain of CO2 to supplement respiratory CO2(met). In contrast, the alternate strategy is less reliant on the sea water supply source, potentially facilitated by increased basal respiration rates and/or a lower photosynthetic demand for CO2. The comparative vulnerability of these alternative strategies to modern ocean conditions is used to explain the global-wide observation that corals with branching morphologies (and thin tissue layers) are generally more thermally sensitive than corals with massive morphologies (and thick tissue layers). The life history implications of this new framework are discussed in terms of contrasting fitness drivers and past environmental constraints, which delivers ominous predictions for the viability of thin-tissued branching and plating species during the present human-dominated (“Anthropocene”) era of the Earth System.
