Resilience of cold-water coral holobionts to thermal stress
International audience <jats:p> Cold-water corals are threatened by global warming, especially in the Mediterranean Sea where they live close to their upper known thermal limit (i.e. 13°C), yet their response to rising temperatures is not well known. Here, temperature effects on <jats:itali...

International audience <jats:p> Cold-water corals are threatened by global warming, especially in the Mediterranean Sea where they live close to their upper known thermal limit (i.e. 13°C), yet their response to rising temperatures is not well known. Here, temperature effects on <jats:italic>Lophelia pertusa</jats:italic> and <jats:italic>Madrepora oculata</jats:italic> holobionts (i.e. the host and its associated microbiome) were investigated. We found that at warmer seawater temperature (+2°C), <jats:italic>L. pertusa</jats:italic> showed a modification of its microbiome prior to a change in behaviour, leading to lower energy reserves and skeletal growth, whereas <jats:italic>M. oculata</jats:italic> was more resilient. At extreme temperature (+4°C), both species quickly lost their specific bacterial signature followed by lower physiological activity prior to death.

The species-specific response to temperature change highlights that global warming may affect dramatically the main deep-sea reef-builders, which would alter the associated biodiversity and related ecosystem services. </jats:p> |
