“…On the reef slope (50-70 m depth) at Nirvana, two new records of corals for the SFBR were found, Iciligorgia schrammi registered by photographs and Muriceopsis petila that was even collected. The black coral Tanacetipathes hirta, a species recently reported in the windward MCE of San Andrés Island by Sánchez et al (2019a), were also seen in the leeward MCE between 50 and 70 m depth ( Figure 2C).…”

“…The octocoral communities observed between 30 and 50 m depth were similar to those found on shallower zones with a dominance of species like Antillogorgia spp. and Eunicea spp., some of them previously recorded at similar depths in the windward reefs of the island (Sánchez et al, 2019a). The colonization of shallow-water coral species into deeper zones in SAI can be explained by a high light penetration that reaches deep areas in this insular region, which could be promoting an ecological divergence in some species according to Sánchez et al (2019b).…”

“…However, even in the Caribbean most MCE are unexplored as research has focused on specific locations (i.e., Bahamas, Cayman, Mesoamerican Reef, Jamaica, Puerto Rico, US Virgin Islands, Curacao, and Bonaire; Loya et al, 2019), such that geographic biases remain at the regional scale. For example, only four publications exist on Colombian MCE (Gonzalez-Zapata et al, 2018a,b;Chasqui and González, 2019;Sánchez et al, 2019a), one of such offer data on corals diversity in the fore-reef slope of the eastern side (windward) of San Andrés Island (SAI), which account for 33 species (Sánchez et al, 2019a).…”

“…On the other hand, the mesophotic zone is located in the deeper photic zone, twilight zone, at a depth ranging from 30 to 40 m, which corresponds to the limit of conventional SCUBA diving, to >150 m, where there is sufficient sunlight penetration to support photosynthesis and living zooxanthellate corals (Kahng et al, 2014;Cerrano et al, 2019). In tropical and subtropical regions, mesophotic ecosystems are receiving scientific attention as they may offer refuge to shallow species due to their less altered environmental conditions (e.g., Baldwin et al, 2018;Bo et al, 2019;Sánchez et al, 2019). In the Mediterranean Sea, diversified habitats are hosted in the mesophotic zone.…”

Sharing and Distinction in Biodiversity and Ecological Role of Bryozoans in Mediterranean Mesophotic Bioconstructions

et al. 2020

Bryozoan assemblages of three mesophotic habitats, recently found in the Adriatic and Ionian Seas, were investigated in terms of species composition and diversity, colonial growth forms, and species ecological affinity, with the purposes to analyze variations and similarities between the different bioconstructions and to compare the mesophotic assemblages with those of other benthic habitats. Bryozoans came from three sites off the Apulian coast: Monopoli, 30–55-m depth, where scleractinians are dominant; Otranto, 45–64-m depth; and Santa Maria di Leuca, 45–70-m depth, where the bivalve Neopycnodonte cochlear is the main bioconstructor. A total number of 50 species of bryozoans were recorded, accounting for about 10% of the total number of Mediterranean species. Only few species were shared between the three sites, whereas a considerable pool of species was characteristic of each site. The β-diversity and Sörensen similarity analyses highlighted the highest similarity between the two southern sites, Otranto and Santa Maria di Leuca, with respect to the northern site of Monopoli, in agreement with the hydrological pattern of the area. The encrusting zoarial type was the most abundant in each site, and few species with erect, celleporiform and petraliform colonies were found. The Sörensen similarity, based on data of zoarial forms composition, revealed values considerably higher than those based on species composition, thus highlighting the similar ecological role played by the bryozoans in all the sites. Moreover, significant differences between the mesophotic bryozoan assemblages and those of other benthic Mediterranean habitats were highlighted, showing higher affinity with the coralligenous and detritic sciaphilic habitats. The relevant ecological role of bryozoans as binders in the bioconstructions of the Mediterranean mesophotic zone has been exhibited.

“…To the untrained eye, A. undata can be easily confused with A. grahamae. Both species occur predominantly in the mesophotic zone (Sherman et al 2010;Bongaerts et al 2015;Appeldoorn et al 2016;Hoeksema et al 2017b;Sánchez et al 2019). The calices of A. undata are mostly arranged in rows underneath ridges with rounded tops, directing in outward direction, but starting more or less separated (Fig.…”

The Caribbean scleractinian reef coral Agaricia undata (Agariciidae) is recorded for the first time as a host of the coral-gall crab Opecarcinus hypostegus (Cryptochiridae). The identity of the crab was confirmed with the help of DNA barcoding. The association has been documented with photographs taken in situ at 25 m depth and in the laboratory. The predominantly mesophotic depth range of the host species suggests this association to be present also at greater depths. With this record, all seven Agaricia species are now listed as gall-crab hosts, together with the agariciid Helioseris cucullata. Within the phylogeny of Agariciidae, Helioseris is not closely related to Agaricia. Therefore, the association between Caribbean agariciids and their gallcrab symbionts may either have originated early in their shared evolutionary history or later as a result of host range expansion. New information on coral-associated fauna, such as what is presented here, leads to a better insight on the diversity, evolution, and ecology of coral reef biota, particularly in the Caribbean, where cryptochirids have rarely been studied.
