Global carbon dioxide efflux from rivers enhanced by high nocturnal emissions

Tom Ian Battin, Hannes Markus Peter, Asa Lovisa Viktoria Horgby, Luis Gómez Gener

Carbon dioxide (CO2) emissions to the atmosphere from running waters are estimated to be four times greater than the total carbon (C) flux to the oceans. However, these fluxes remain poorly constrained because of substantial spatial and temporal variabilit ...

Changing atmospheric acidity as a modulator of nutrient deposition and ocean biogeochemistry

Athanasios Nenes

Anthropogenic emissions to the atmosphere have increased the flux of nutrients, especially nitrogen, to the ocean, but they have also altered the acidity of aerosol, cloud water, and precipitation over much of the marine atmosphere. For nitrogen, acidity-d ...

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 ...

High summer temperatures amplify functional differences between coral‐ and algae‐dominated reef communities

Nils Rädecker, Hal Hunt Jones II

Shifts from coral to algal dominance are expected to increase in tropical coral reefs as a result of anthropogenic disturbances. The consequences for key ecosystem functions such as primary productivity, calcification, and nutrient recycling are poorly und ...

A modern scleractinian coral with a two-component calcite–aragonite skeleton

Anders Meibom, Jaroslaw Hubert Stolarski

One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. All modern scleractinian corals are thought to produce skeletons exclusively of the calcium-carbonate polymorph aragonite. ...

Seascape genomics as a new tool to empower coral reef conservation strategies: an example on north‐western Pacific Acropora digitifera

Stéphane Joost, Estelle Rochat, Oliver Michele Selmoni

Coral reefs are suffering a major decline due to the environmental constraints imposed by climate change. Over the last 20 years, three major coral bleaching events occurred in concomitance with anomalous heatwaves, provoking a severe loss of coral cover w ...

Seascape genomics to empower coral reef conservation strategies

Oliver Michele Selmoni

The future of coral reefs is under threat since anomalous heat waves are causing the death of reef building corals around the world. This phenomenon, known as "coral bleaching", has already resulted in widespread loss of coral over the past 30 years. Witho ...

Photic stress on coral reefs in the Maldives: The Amphistegina bleaching index

Aurélie Angéloz, Anaël Lehmann, Arthur Adams

The Amphistegina Bleaching Index (ABI) was applied to three Maldivian reefs in the Rasdhoo and North Ari Atolls in 2018, during normal sea surface temperature conditions. This dataset was then compared with a 2015, pre-coral bleaching study. The results pr ...

Coral cover surveys corroborate predictions on reef adaptive potential to thermal stress

Stéphane Joost, Oliver Michele Selmoni, Véronique Berteaux-Lecellier

As anomalous heat waves are causing the widespread decline of coral reefs worldwide, there is an urgent need to identify coral populations tolerant to thermal stress. Heat stress adaptive potential is the degree of tolerance expected from evolutionary proc ...

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 ...
