Coral Reefs Under Rapid Climate Change and Ocean Acidification
As the International Year of the Reef 2008 begins, scaled-up management intervention and decisive action on global emissions are required if the loss of coral-dominated ecosystems is to be avoided. Expand
Different algal symbionts explain the vertical distribution of dominant reef corals in the eastern Pacific
The findings indicate that each coral species hosts a distinct algal taxon adapted to a particular light regime, which constitutes an important axis for niche diversification and is sufficient to explain the vertical distribution patterns of these two coral species. Expand
Photosynthetic response to elevated temperature in the symbiotic dinoflagellate Symbiodinium microadriaticum in culture.
Results indicate that photosynthesis is impaired at temperatures above 30 degrees C and ceases completely at 34-36 degrees C, and possible mechanisms that may function in the disassociation of algal-invertebrate symbioses in response to elevated temperature are discussed. Expand
Acclimation and adaptation to irradiance in symbiotic dinoflagellates. I. Responses of the photosynthetic unit to changes in photon flux density
The results suggest that symbiont photo- Adaptation may constitute an important axis of niche diversification for the intact associations and photo-acclunatory adjustment in symbiotic dinoflagellates may be under genetic constraints, and thus may represent photo-adaptation. Expand
Nitrogen fixation by symbiotic cyanobacteria provides a source of nitrogen for the scleractinian coral Montastraea cavernosa
The results presented here show that the zooxanthellae of M. cavernosa acquire nitrogen from cyanobacterial nitrogen fixation, and that the distribution of corals with symbiotic cyanobacteria is positively correlated with increasing depth. Expand
On the circulation in the Puerto Morelos fringing reef lagoon
For a period of 22 months beginning in September 2003, an array of four current profilers were deployed on the Puerto Morelos fringing reef lagoon, a microtidal Caribbean environment characterised byExpand
Calcification in bleached and unbleached Montastraea faveolata: evaluating the role of oxygen and glycerol
Results indicate that calcification in symbiotic corals is not strictly a “light-enhanced” or “dark-repressed” process, but rather, the products of photosynthesis have a critical role in calcification, which should be viewed as a ‘photosynthesis-driven’ process. Expand
Response of two species of Indo-Pacific corals, Porites cylindrica and Stylophora pistillata, to short-term thermal stress: The host does matter in determining the tolerance of corals to bleaching
It is concluded that P. cylindrica contains a heat resistant C15 Symbiodinium and critical host proteins are present at higher concentrations than observed for S. pistillata, the combination of which provides greater protection from bleaching conditions of high temperature in the light. Expand
Multiple light scattering and absorption in reef-building corals.
A simplified optical model of the coral is proposed and it is shown that, through scattering, the skeleton homogenizes and enhances the light environment in which the symbionts live. Expand
Avoiding Coral Reef Functional Collapse Requires Local and Global Action
Budget reconstructions using documented ecological perturbations drive shallow Caribbean forereefs toward an increasingly fragile carbonate balance and the benefits of local conservation and global action on climate change are contrasted. Expand
