Experiments were performed in controlled conditions in order to investigate the effect of light and/or feeding on the δ 15 N composition of zooxanthellae and animal tissue of a scleractinian coral, Stylophora pistillata. For this purpose, corals were cultured under 3 light levels (80, 200, and 300 µmol photons m -2 s -1 ) and for each light level, half of the corals were fed twice a week with nat- ural zooplankton while the other half, the control group, were starved. To understand how plankton…

Summer autotrophy and winter heterotrophy in the temperate symbiotic coral Cladocora caespitosa
TLDR
Evidence is given that C. caespitosa and temperate corals in general derive a large fraction of their energy from heterotrophic feeding in winter.
The Effects of Temperature, Light, and Feeding on the Physiology of Pocillopora damicornis, Stylophora pistillata, and Turbinaria reniformis Corals
Evidence has shown that individually feeding or reduced light can mitigate the negative effects of elevated temperature on coral physiology. We aimed to evaluate if simultaneous low light and feeding

TLDR
Corals, including tropical, deep- and cold-water species, are known as a major source of carbon and other nutrients for benthic communities through the secretion of mucus, despite wide variation in chemical composition.
Toward a standardised protocol for the stable isotope analysis of scleractinian corals.
TLDR
Whether treatments that are commonly used to prepare scleractinian coral samples for stable isotope analysis yield different δ15 N and δ13 C values is determined, and guidelines toward a standardised protocol are provided.
Nutrient acquisition in four Mediterranean gorgonian species
TLDR
Comparison of the isotopic signatures of the gorgonian tissues and the food sources indicated that E. singularis and P. clavata had the same diet in both winter and summer, and their role in the flow of particulate matter between the water column and the benthos is explained.
Testing assumptions of nitrogen cycling between a temperate, model coral host and its facultative symbiont: symbiotic contributions to dissolved inorganic nitrogen assimilation
Coral symbioses are predicated on the need for mutual nutrient acquisition and translocation between partners. Carbon translocation is well-studied in this classic mutualism, while nitrogen (N) has
Isotopic approaches to estimating the contribution of heterotrophic sources to Hawaiian corals
Corals obtain nutrition from the photosynthetic products of their algal endosymbionts and the ingestion of organic material and zooplankton from the water column. Here, we use stable carbon (δ13C)
Trophic ecology of the facultative symbiotic coral Oculina arbuscula
TLDR
This study provides new insights into this feeding mode in these reef-building organisms as this small planktonic fraction has been overlooked as a potential food source for symbiotic scleractinian corals.

Effect of feeding on the carbon and oxygen isotopic composition in the tissues and skeleton of the zooxanthellate coral Stylophora pistillata
TLDR
The effect of feeding on the carbon isotopic composition of zooxanthellae, animal tissue and skeleton was investigated in the scleractinian coral Stylophora pistillata and suggests that the skeletal δ 13 C is not sensitive to heterotrophic food supply.
Uptake of ammonium by the scleractinian coral Stylophora pistillata: Effect of feeding, light, and ammonium concentrations
TLDR
It is suggested that an external concentration of ammonium equal to 0.6 mM can sustain the growth of the zooxanthellae population.
Effect of light and feeding on the fatty acid and sterol composition of zooxanthellae and host tissue isolated from the scleractinian coral Turbinaria reniformis
TLDR
The importance of feeding in sustaining coral metabolism, especially when light, or stress events, is limiting photosynthesis, is highlighted in this study.
Effect of nutrient enrichment on growth and photosynthesis of the zooxanthellate coral Stylophora pistillata
TLDR
High ammonium and relatively low phosphorus concentrations are required to induce a significant decrease in coral growth rate and corals with the highest percent increases in maximal gross photosynthetic rate had the smallest decreases in growth rate due to nutrient enrichment.
Effect of natural zooplankton feeding on the tissue and skeletal growth of the scleractinian coral Stylophora pistillata
TLDR
Even moderate levels of feeding enhanced both tissue and skeletal growth, although the processes involved in this enhancement remain to be determined.
Microheterotrophy in the zooxanthellate coral Stylophora pistillata: Effects of light and ciliate density
TLDR
Zooplankton feeding seems to complement autotrophic nutrition under high light, and the small amount of microplankton ingested may provide nitrogen, phosphorus, or vitamins to corals, and this food supply may be especially important in tropical waters where inorganic nutrient concentrations are low.
Urea uptake by the scleractinian coral Stylophora pistillata
Assimilation and partitioning of prey nitrogen within two anthozoans and their endosymbiotic zooxanthellae
TLDR
Differences in 15 N enrichment among amino acids were consistent with known synthesis and transformation pathways, but it was not possible to discriminate between host feeding and de novo synthesis.
Ammonium metabolism in the zooxanthellate coral, stylophora pistillata
TLDR
The results suggest that GDH activity and dark respiration rates may be used to estimate quantitatively the rate of ammonium excretion in S. pistillata, and that recycled nitrogen accounts for 90% of the zooxanthellae nitrogen demand.
