Fast and pervasive transcriptomic resilience and acclimation of extremely heat-tolerant coral holobionts from the northern Red Sea

Anders Meibom, Maoz Fine, Romain Savary, Guilhem Maurice Louis Banc-Prandi

Corals from the northern Red Sea and Gulf of Aqaba exhibit extreme thermal tolerance. To examine the underlying gene expression dynamics, we exposed Stylophora pistillata from the Gulf of Aqaba to short-term (hours) and long-term (weeks) heat stress with p ...

Intracellular competition for nitrogen controls dinoflagellate population density in corals

Julia Marie Jeanne Yvonne Bodin, Anders Meibom, Stéphane Laurent Escrig, Maria-Evangelia Giovani, Thomas Krüger, Maoz Fine

The density of dinoflagellate microalgae in the tissue of symbiotic corals is an important determinant for health and productivity of the coral animal. Yet, the specific mechanism for their regulation and the consequence for coral nutrition are insufficien ...

A Closing Window of Opportunity to Save a Unique Marine Ecosystem

Anders Meibom, Maoz Fine

Five years in the making, a massive oil spill of 1 million barrels is imminent in the Red Sea off the coast of Yemen. Emergent action must be taken by the United Nations and its International Maritime Organization (IMO) to remove the oil, despite regional ...

Science, Diplomacy, and the Red Sea's Unique Coral Reef: It's Time for Action

Anders Meibom, Maoz Fine

Rapid ocean warming due to climate change poses a serious risk to the survival of coral reefs. It is estimated that 70-90 percent of all reefs will be severely degraded by mid-century even if the 1.5 degrees C goal of the Paris Climate Agreement is achieve ...

A method to disentangle and quantify host anabolic turnover in photosymbiotic holobionts with subcellular resolution

Arnaud Comment, Anders Meibom, Maoz Fine, Emma Mary Gibbin, Guilhem Maurice Louis Banc-Prandi

A wide range of organisms host photosynthesizing symbionts. In these animals the metabolic exchange between host and symbionts has prevented in situ host anabolic turnover to be studied without the confounding effect of translocated photosynthates. Using t ...

Temperature and feeding induce tissue level changes in autotrophic and heterotrophic nutrient allocation in the coral symbiosis – A NanoSIMS study

Julia Marie Jeanne Yvonne Bodin, Anders Meibom, Stéphane Laurent Escrig, Thomas Krüger, Maoz Fine, Céline Edith Loussert-Fonta

Corals access inorganic seawater nutrients through their autotrophic endosymbiotic dinoflagellates, but also capture planktonic prey through heterotrophic feeding. Correlating NanoSIMS and TEM imaging, we visualized and quantified the subcellular fate of a ...

Common reef-building coral in the Northern Red Sea resistant to elevated temperature and acidification

Julia Marie Jeanne Yvonne Bodin, Anders Meibom, Stéphane Laurent Escrig, Maria-Evangelia Giovani, Thomas Krüger, Maoz Fine

Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors, and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the ...

Measuring coral calcification under ocean acidification: methodological considerations for the 45Ca-uptake and total alkalinity anomaly technique

Stéphanie Kéren Cohen, Thomas Krüger, Maoz Fine

As the oceans become less alkaline due to rising CO2 levels, deleterious consequences are expected for calcifying corals. Predicting how coral calcification will be affected by on-going ocean acidification (OA) requires an accurate assessment of CaCO3 depo ...
