Heterotrophy in Tropical Scleractinian Corals
TLDR
A recent study showed that during bleaching events some coral species, by increasing their feeding rates, are able to maintain and restore energy reserves.
Coral and mollusc resistance to ocean acidification adversely affected by warming
Increasing atmospheric carbon dioxide (CO2) concentrations are expected to decrease surface ocean pH by 0.3‐0.5 units by 2100 (refs 1,2), lowering the carbonate ion concentration of surface waters.
Interactions between zooplankton feeding, photosynthesis and skeletal growth in the scleractinian coral Stylophora pistillata
TLDR
The results suggest that the increase in the rates of calcification in fed corals might be induced by a feeding-stimulation of organic matrix synthesis.
Diazotrophs: a non-negligible source of nitrogen for the tropical coral Stylophora pistillata
TLDR
It is estimated that the ingestion of diazotrophs provides 0.76±0.15 µg N cm−2 h−1, suggesting that diazOTrophs represent a non-negligible source of nitrogen for scleractinian corals.
Effect of light and feeding on the nitrogen isotopic composition of a zooxanthellate coral: role of nitrogen recycling
TLDR
There was a depletion in tissue and zooxanthellae 15 N of fed corals compared to the controls, and this depletion did not follow the general food-web rule in which predators are enriched in 15 N by 3.5‰ compared to prey, but can be explained by the fact that nitrogen is recycled within the symbiotic association.
Bioaccumulation of zinc in the scleractinian coral Stylophora pistillata
The uptake kinetics of zinc (Zn), an essential nutrient for both photosynthesis and calcification, in the tissue of S. pistillata showed that the transport of Zn is composed of a linear component
Responses of Two Scleractinian Corals to Cobalt Pollution and Ocean Acidification
TLDR
This study reveals that some reefs may be yet subjected to deleterious pollution levels, and even if no interaction between pCO2 levels and cobalt concentration has been found, it is likely that coral metabolism will be weakened if they are subjected to additional threats such as temperature increase, other heavy metals, and eutrophication.
Vital effects in coral skeletal composition display strict three‐dimensional control
Biological control over coral skeletal composition is poorly understood but critically important to paleo‐environmental reconstructions. We present micro‐analytical measurements of trace‐element
