Unraveling the impact of marine heatwaves on the Eukaryome of the emblematic Mediterranean red coral <i>Corallium rubrum</i>.

ABSTRACT: Global warming is intensifying heatwaves worldwide, leading to more frequent and severe temperature extremes. This study investigates the impact of the unprecedented 2022 Mediterranean heatwaves on the coral eukaryome, which has received little attention despite its known importance to coral holobiont functioning. Fifty-six colonies of the iconic red coral Corallium rubrum from the Mediterranean Sea were collected at different sites, depths, and health states. The microeukaryotic communities were analyzed using an 18S rRNA gene metabarcoding approach. Primers were designed to reduce amplification of the 18S rRNA gene sequences of the red coral while being universal for amplification of microeukaryotes. Our results showed that the red coral eukaryome was dominated by Di
