Methods
We used coralligenous assemblage data from five sites located within two marine protected areas in the NW Mediterranean Sea: the Port-Cros National Park and Scandola Natural Reserve. Three sites, one in Port-Cros (Gabin_par) and two in Scandola (Pzzu_par and Pzzinu_par), are exposed vertical walls dominated by the red gorgonian Paramuricea clavata. A total of 24 photographic quadrats of 25 × 25 cm (replicates) were analysed for each site and temporal point, resulting in 360 pictures in total. The sampling unit (625 cm2 per replicate) was selected following Kipson et al. (2011) and Casas-Güell et al. (2015). The percent cover of the different macro-benthic sessile species was calculated in each quadrat by over-imposing 100 stratified random points and identifying the underlying species to the lowest possible taxonomic level, using Photoquad photoquadrat (Trygonis & Sini, 2012).
