Gene expression of Pocillopora damicornis coral larvae in response to acidification and ocean warming
Objectives The endosymbiosis with Symbiodiniaceae is key to the ecological success of reef-building corals. However, climate change is threatening to destabilize this symbiosis on a global scale. Most studies looking into the response of corals to heat str ...
London2024Excess labile carbon promotes diazotroph abundance in heat-stressed octocorals
Nitrogen limitation is the foundation of stable coral-algal symbioses. Diazotrophs, prokaryotes capable of fixing N-2 into ammonia, support the productivity of corals in oligotrophic waters, but could contribute to the destabilization of holobiont function ...
ROYAL SOC2023Metabolism of the symbiotic jellyfish Cassiopea in a changing environment
Ocean warming and other anthropogenic impacts have led to a global decline in many photosymbiotic cnidarians, most notably reef-building corals. But some species of the symbiotic and (sub-)tropical upside-down jellyfish Cassiopea are increasingly reported ...
EPFL2023The Reef Environment Centralized InFormation System (RECIFS) : An integrated geo‐environmental database for coral reef research and conservation
Stéphane Joost, Oliver Michele Selmoni
Motivation: Host to intricate networks of marine species, coral reefs are among the most biologically diverse ecosystems on Earth. Over the past few decades, major degradations of coral reefs have been observed worldwide, which is largely attributed to the ...
2023Photobiology and metabolic interactions in the symbiotic jellyfish Cassiopea
The symbiont-bearing jellyfish Cassiopea live a benthic lifestyle, positioning themselves upside-down on sediments in shallow waters to allow their endosymbiotic algae to photosynthesize in the sunlight. Over the last decades Cassiopea has become increasin ...
EPFL2023Coupled carbon and nitrogen cycling regulates the cnidarian–algal symbiosis
Anders Meibom, Stéphane Laurent Escrig, Nils Rädecker
Efficient nutrient recycling underpins the ecological success of cnidarian-algal symbioses in oligotrophic waters. In these symbioses, nitrogen limitation restricts the growth of algal endosymbionts in hospite and stimulates their release of photosynthates ...
2023Metal Catalysts for the Electrochemical Reduction of CO2
The world by and large has adopted the The Paris Agreement, which commits any signing party to cut greenhouse emissions drastically and prevent global heating above 2 °C beyond pre-industrial levels. For this ambitious goal to be met, ratifying states need ...
EPFL2023A roadmap to understanding diversity and function of coral reef-associated fungi
Tropical coral reefs are hotspots of marine productivity, owing to the association of reef-building corals with endosymbiotic algae and metabolically diverse bacterial communities. However, the functional importance of fungi, well-known for their contribut ...
OXFORD UNIV PRESS2022Heat stress destabilizes symbiotic nutrient cycling in corals
Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz
Recurrent mass bleaching events are pushing coral reefs worldwide to the brink of ecological collapse. While the symptoms and consequences of this breakdown of the coral–algal symbiosis have been extensively characterized, our understanding of the underlyi ...
2021Microbes support enhanced nitrogen requirements of coral holobionts in a high CO 2 environment
Nils Rädecker, Gabriela Hannah Holligan Perna
Ocean acidification is posing a threat to calcifying organisms due to the increased energy requirements of calcification under high CO2 conditions. The ability of scleractinian corals to cope with future ocean conditions will thus depend on their ability t ...
