The correlation between solar radiation and sea surface temperature (SST) and growth was assessed along a latitudinal gradient. Extension rate and skeletal density were both correlated with calcification rate, indicating that calcium carbonate deposition was allocated evenly between skeletal density and linear extension. Unlike most studies on other tropical and temperate corals, in which calcification was positively correlated with solar radiation and SST, in the present study calcification… 

Inferred calcification rate of a Mediterranean azooxanthellate coral is uncoupled with sea surface temperature along an 8° latitudinal gradient

The lower sensitivity of L. pruvoti to SST with respect to other sympatric zooxanthellate corals, such as Balanophyllia europaea, may rely on the absence of a temperature induced inhibition of photosynthesis, and thus the absenceof an inhibition of the calcification process.

Environmental and physiochemical controls on coral calcification along a latitudinal temperature gradient in Western Australia

The results indicate that corals shift their pHcf to adapt and/or acclimatize to their localized thermal regimes, likely to have critical implications for predicting the future of coral reefs under CO2 -driven warming and acidification.

Mechanisms and seasonal drivers of calcification in the temperate coral Turbinaria reniformis at its latitudinal limits

High-latitude coral reefs provide natural laboratories for investigating the mechanisms and limits of coral calcification. While the calcification processes of tropical corals have been studied

Latitudinal variations in biometry and population density of a Mediterranean solitary coral

A higher tolerance to temperature for non-zooxanthellate species seems to be confirmed when extrapolating the relationships between biological parameters of the three species and SST, according to the projected seawater temperature increase.

Population dynamics of a temperate coral along a depth gradient in the Dardanelles

Notwithstanding the importance of analyzing the variations of population dynamic traits along environmental gradients for assessing coral resilience to global climate change, temperate areas are more

Negative response of photosynthesis to natural and projected high seawater temperatures estimated by pulse amplitude modulation fluorometry in a temperate coral

The photosynthetic efficiency of B. europaea photosynthesis is progressively depressed at temperatures >21.6°C, supporting previous hypotheses raised by the studies on growth and demography of this species and confirming the threats posed to this species by the ongoing seawater warming.

Reproductive output of a non-zooxanthellate temperate coral is unaffected by temperature along an extended latitudinal gradient

This is the first field investigation of the relationship between reproductive output and temperature increase of a temperate asymbiotic coral, providing novel insights into the poorly studied non-zooxanthellate scleractinians.

Ocean warming and acidification synergistically increase coral mortality

A synergistic adverse effect on mortality rates is shown, for solitary and colonial, symbiotic and asymbiotic corals, suggesting that high seawater temperatures may have increased their metabolic rates which, in conjunction with decreasing pH, could have led to rapid deterioration of cellular processes and performance.

Reproductive Efficiency of a Mediterranean Endemic Zooxanthellate Coral Decreases with Increasing Temperature along a Wide Latitudinal Gradient

Investigating variations in reproductive output associated with local seawater temperature along a wide latitudinal gradient on the western Italian coast found that in a progressively warming Mediterranean, the efficiency of the energy invested in reproduction could be considerably reduced in this species, thereby affecting vital processes.

Low and variable pH decreases recruitment efficiency in populations of a temperate coral naturally present at a CO2 vent

Atmospheric carbon dioxide enrichment alters seawater carbonate chemistry, thus threatening calcifying organisms such as corals. Coral populations at carbon dioxide vents are natural acidification



Growth responses of the reef-building coral Montastraea annularis along a gradient of continental influence in the southern Gulf of Mexico

The data suggest that, as corals experience a harsher environment, they respond by extending their skeleton more with the same or less calcium carbonate, with a concomitant reduction of skeletal density.

Relationships between growth, population structure and sea surface temperature in the temperate solitary coral Balanophyllia europaea (Scleractinia, Dendrophylliidae)

The demographic characteristics of the solitary zooxanthellate scleractinian Balanophyllia europaea, endemic to the Mediterranean, were determined in six populations, on a latitudinal gradient along

Variation in biometry and population density of solitary corals with solar radiation and sea surface temperature in the Mediterranean Sea

It is hypothesized that the negative effect of temperature on biometry and population density of B. europaea depends on photosynthesis inhibition of symbiotic zooxanthellae at high temperatures, which would lower the calcification rate and availability of energetic resources.

Interacting effects of CO2 partial pressure and temperature on photosynthesis and calcification in a scleractinian coral

It is shown here that CO2 partial pressure (pCO2) and temperature significantly interact on coral physiology, and warrants a re-evaluation of the projected decrease of marine calcification by the year 2100.

Skeletal extension, density and calcification of the reef coral, Montastrea annularis: St. Croix, U.S. Virgin Islands

Parameters of the annual and subannual skeletal growth of 61 Montastrea annularis corals, collected at a variety of shallow depth sites on reefs of St. Croix, U.S. Virgin Islands, are determined by

Comment on “Coral reef calcification and climate change: The effect of ocean warming”

McNeil et al. [2004] attempt to address an important question about the interactions of temperature and carbonate chemistry on calcification, but their projected values of reef calcification are
