... Great Barrier Reef Metabolite Photosynthesis Light availability fundamentally regulates the ecological success of reef-building corals over space and time ( Muir et al., 2015 ). However, corals within shallow reef habitats are exposed to light intensities that continually change over both...

...Ronald Osinga; Marlous Derksen-Hooijberg; Tim Wijgerde; Johan A. J. Verreth ABSTRACT Rates of dark respiration and net photosynthesis were measured for six replicate clonal fragments of the stony coral Galaxea fascicularis (Linnaeus 1767), which were incubated under 12 different combinations...

We measured multiple physiological traits (including symbiont density, calcification, photosynthesis and tissue composition) for the same coral fragments to facilitate direct comparisons between species ( Stylophora pistillata , Pocillopora...

Specifically, levels of these response variables were higher in samples exposed to a variable temperature regime, suggesting that S. hystrix may acclimate to fluctuating temperatures by increasing its capacity for photosynthesis. * Author...

Thus, this study investigates OM fluxes along with other key physiological parameters (i.e. photosynthesis, respiration...

This approach allowed us to quantify the rate at which adjustments to physiology occurred, as well as the magnitude of up- or downregulation of both feeding modes. In addition...

Because E. singularis is a symbiotic species, we have also discussed the potential role...

.... The coral response to a change in both light and temperature was also assessed, by subjecting coral to two treatments corresponding to winter (14°C and 30 μmol m –2 s –1 ) and summer (23°C and 250 μmol m –2 s –1 ) conditions, as measured in the Ligurian Sea. Photosynthesis, measured using both respirometry...
