We assessed the uptake rates of nitrate by the scleractinian coral Stylophora pistillata by following 15N from seawater into the coral tissue. Two sets of corals were first prepared, with “nitrate‐enriched” corals grown in 5 µmol L−1 NO3− and control corals grown in ≤µmol L−1 NO3−. Uptake rates at 0.3 and 3 µmol L−1 [15N]NO3− were then measured. Most of the %15N enrichment occurred in the zooxanthellae fraction. Uptake rates were not significantly different between nitrate‐enriched and control… 

High phosphate uptake requirements of the scleractinian coral Stylophora pistillata

New insights are brought into the relationships between nutrients and symbiotic corals, and the rate of phosphate uptake decreased with particulate feeding of the host (organic phosphate source), which highlights some greater limitation in phosphate rather than in nitrogen.

Uptake of dissolved free amino acids by the scleractinian coral Stylophora pistillata

The value of the carrier affinity indicated good adaptation of the corals to the low levels of DFAA concentrations measured in most oligotrophic waters, and dissolved organic and inorganic nitrogen can supply almost 100% of the nitrogen needs for tissue growth.

Divergent Capacity of Scleractinian and Soft Corals to Assimilate and Transfer Diazotrophically Derived Nitrogen to the Reef Environment

This study suggests that DDN assimilation into coral tissues depends on the presence of active diazotrophs in the coral’s mucus layer and/or surrounding seawater, which has implications for N availability and reef biogeochemistry in scleractinian versus soft coral-dominated reefs.

Effects of nitrate and phosphate availability on the tissues and carbonate skeleton of scleractinian corals

: To study the effects of nutrient availability on scleractinian corals, fragments of Monti pora digitata and Porites cylindrica were cultured in nutrient-enriched seawater (nitrate: 1.4 to 1.9 µmol

Importance of a micro-diet for scleractinian corals

Results showed that ingestion rates were proportional to prey concentrations and pico- and nanoplankton may, therefore, constitute an important food source for these coral species.

The Assimilation of Diazotroph-Derived Nitrogen by Scleractinian Corals Depends on Their Metabolic Status

The results suggest that DDN assimilation by corals varies according to the environmental conditions and is likely linked to the capacity of the coral to acquire nutrients from seawater.

Experimental assessment of organic carbon fluxes in the scleractinian coral Stylophora pistillata during a thermal and photo stress event

A substantial stress-induced impact on autoand heterotrophic capacities for energy acquisition in this species is demonstrated, suggesting that this coral species, and possibly other related species, can be severely endangered by reoccurring and widespread bleaching events.

Heterotrophy in Tropical Scleractinian Corals

A recent study showed that during bleaching events some coral species, by increasing their feeding rates, are able to maintain and restore energy reserves.

Heterotrophy in the Mediterranean symbiotic coral Cladocora caespitosa: comparison with two other scleractinian species

This experimental study assessed the grazing rates of the Mediterranean symbiotic coral Cladocora caespitosa on the 4 main food sources available in its natural environment: detrital partic- ulate

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



Uptake of ammonium by the scleractinian coral Stylophora pistillata: Effect of feeding, light, and ammonium concentrations

It is suggested that an external concentration of ammonium equal to 0.6 mM can sustain the growth of the zooxanthellae population.

Ammonium metabolism in the zooxanthellate coral, stylophora pistillata

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.

Nitrate increases zooxanthellae population density and reduces skeletogenesis in corals

It is concluded that enhanced nitrate levels in tropical coastal waters will have a hitherto unrecognized effect on the growth rate of tropical coral reefs.

Nutrient uptake kinetics of freshly isolated zooxanthellae

Evidence is consistent with the hypothesis that nutrient uptake by intact zooxanthellae-host symbioses occurs by diffusion down a concentration gradient created by localized substrate depletion by the zooxanhellae in host tissue.

Nitrate Uptake by Reef Corals

In specimens of the hermatypic coral species Fungia scutaria and Montipora verrucosa and in the alga Ulva lactuca, nitrate uptake was measured in light and dark with a flow-through apparatus. The

Uptake and assimilation of 15NH4+ by a variety of corals

Corals from the Swain Reefs of the Great Barrier Reef were exposed to 15NH4+in sea water, and the disappearance of NH4+from the medium and the appearance of 15N in the corals was followed, which did not describe a normal substrate saturation curve.

Availability of two forms of dissolved nitrogen to the coral Pocillopora damicornis and its symbiotic zooxanthellae

The contribution of DFAAs to the nitrogen budget of P. damicornis constituted only a small fraction of the nitrogen potentially contributed by ammonium under field conditions, and may be an important source of nitrogen when other sources such as ammonium are scarce or during periods when high concentrations of D FAAs become sporadically available.

DIN, DON and P04 flux by a medusa with algal symbionts

Linuche unguiculata, a coronate scyphozoan with symbiotic dinoflagellates (= zooxanthellae), was shown to be capable of taking up NH4, NO3, PO, and 3 amino acids from seawater, and enables the medusae to conserve nutrients by preventing their loss from the association.
