“…Six aquaria were assigned to each gorgonian species, with three aquaria for each thermal condition. The two gorgonian species were kept in separate tanks to avoid interspecies interactions and competition ( 62 ). Each colony was cut into two equal-sized fragments, and the fragments were divided over the two temperature conditions, ensuring that for each thermally stressed coral a paired control sample was present, allowing statistical corrections for colony ( Fig.…”

In the Mediterranean Sea, the tree-shaped gorgonian corals form large forests that provide a place to live for many species. Because of this important ecological role, it is crucial to understand how common habitat-forming gorgonians, like Eunicella cavolini and Paramuricea clavata , are affected by high seawater temperatures that are expected in the future due to climate change.

“…E. cavolini may thus be a competitor for food resources of A. subpinnata , particularly, because the polyp density in E. cavolini is ∼3-fold higher compared with A. subpinnata ( Weinberg, 1976 ; Bo et al, 2018 ). Besides, this gorgonian has been shown to be a strong competitor in physical interactions with other gorgonians ( Turicchia et al, 2020 ). In contrast to A. subpinnata , the prokaryotic communities associated with shallow E. cavolini colonies have been previously described in detail ( van de Water et al, 2017 , 2018b ), showing a relatively stable microbiota dominated by a few bacterial phylotypes, in particular Endozoicomonas .…”

Local Conditions Influence the Prokaryotic Communities Associated With the Mesophotic Black Coral Antipathella subpinnata

Black corals are important habitat-forming species in the mesophotic and deep-sea zones of the world’s oceans because of their arborescent colony structure and tendency to form animal forests. Although we have started unraveling the ecology of mesophotic black corals, the importance of the associated microbes to their health has remained unexplored. Here, we provide in-depth assessments of black coral-microbe symbioses by investigating the spatial and temporal stability of these associations, and make comparisons with a sympatric octocoral with similar colony structure. To this end, we collected samples of Antipathella subpinnata colonies from three mesophotic shoals situated along the Ligurian Coast of the Mediterranean Sea (Bordighera, Portofino, Savona) in the spring of 2017. At the Portofino shoal, samples of A. subpinnata and the gorgonian Eunicella cavolini were collected in November 2016 and May 2017. Bacterial communities were profiled using 16S rRNA gene amplicon sequencing. The bacterial community of E. cavolini was consistently dominated by Endozoicomonas . Contrastingly, the black coral microbiome was more diverse, and was primarily composed of numerous Bacteroidetes, Alpha- and Gammaproteobacterial taxa, putatively involved in all steps of the nitrogen and sulfur cycles. Compositional differences in the A. subpinnata microbiome existed between all locations and both time points, and no phylotypes were consistently associated with A. subpinnata . This highlights that local conditions may influence the bacterial community structure and potentially nutrient cycling within the A. subpinnata holobiont. But it also suggests that this coral holobiont possesses a high degree of microbiome flexibility, which may be a mechanism to acclimate to environmental change.
