Previous observations suggested that microbial communities contribute to coral health and the ecological resilience of coral reefs. However, most studies of coral microbiology focused on prokaryotes and the endosymbiotic algae Symbiodinium. In contrast, knowledge concerning diversity of other protists is still lacking, possibly due to methodological constraints. As most eukaryotic DNA in coral samples was derived from hosts, protist diversity was missed in metagenome analyses. To tackle this issue, we designed blocking primers for Scleractinia sequences amplified with two primer sets that targeted variable loops of the 18S rRNA gene (18SV1V2 and 18SV4). These blocking primers were used on environmental colonies of Pocillopora damicornis sensu lato from two...

Habitat suitability and environmental niche comparison of cold-water coral species along the Brazilian continental margin

Reveillaud, J; Freiwald, A; Van Rooij, D; Le Guilloux, Erwan; Altuna, A; Foubert, A; Vanreusel, A; Olu, Karine; Henriet, J.

Studies on the distribution of scleractinian corals in the Bay of Biscay were relatively numerous during the nineteenth and the first half of the twentieth century. Yet, recent reports are scattered, sometimes unpublished, and therefore knowledge about the current coral occurrence in the area is limited. This study aims at compiling the available historical and more recently collected information on the occurrence of scleractinian corals in the Bay of Biscay. Data from two recent cruises are included and compared with previous explored coral sites from as early as 1830 up to 1995. A database of 347 records including 34 described species of scleractinians highlights that the slope of the Bay of Biscay is an important habitat for scleractinians. This could...

Scleractinian corals (Fungiidae, Agariciidae and Euphylliidae) of Pulau Layang-Layang, Spratly Islands, with a note on Pavona maldivensis (Gardiner, 1905)

Barbosa, Romina; Davies, A. J.; Sumida, P. Y. G..

In face of increasing anthropogenic disturbance in the deep sea, it is a priority to better understand the regional distribution of cold-water corals (CWC). These organisms create some of the most species-rich habitats in the deep sea and, for this reason, they must be properly protected and managed. In this study, we aimed to identify suitable habitat for multiple CWC taxa off the Brazilian continental margin and compare their environmental niches. Habitat suitability models were developed using the Maxent approach, which allowed for the prediction of species distribution and for the identification of potential 'hot spot' areas that may be important for biodiversity conservation. Ecological niches were determined by a PCA-env approach, and niche...

Layang-Layang is a small island part of an oceanic atoll in the Spratly Islands off Sabah, Malaysia. As the reef coral fauna in this part of the South China Sea is poorly known, a survey was carried out in 2013 to study the species composition of the scleractinian coral families Fungiidae, Agariciidae and Euphylliidae. A total of 56 species was recorded. The addition of three previously reported coral species brings the total to 59, consisting of 32 Fungiidae, 22 Agariciidae, and five Euphylliidae. Of these, 32 species are new records for Layang-Layang, which include five rarely reported species, i.e., the fungiids Lithophyllon ranjithi, Podabacia sinai, Sandalolitha boucheti, and the agariciids Leptoseris kalayaanensis and L. troglodyta. The coral fauna...

García-Arredondo,Alejandro; Rojas-Molina,Alejandra; Ibarra-Alvarado,César; Lazcano-Pérez,Fernando; Arreguín-Espinosa,Roberto; Sánchez-Rodríguez,Judith.

Abstract Background: Scleractinian corals (stony corals) are the most abundant reef-forming cnidarians found in coral reefs throughout the world. Despite their abundance and ecological importance, information about the diversity of their toxins and their biological activities is very scarce. In this study, the chemical composition and the biological activities of the aqueous extracts of Pseudodiploria strigosa, Porites astreoides and Siderastrea siderea, three scleractinian corals from the Mexican Caribbean, have been assessed for the first time. Methods: Toxicity of the extracts was assessed in crickets; the presence of cytolysins was detected by the hemolysis assay; the vasoconstrictor activity was determined by the isolated rat aortic ring assay; the...

A revision of the Shallow-water Azooxanthellate Scleractinia of the Western Atlantic

Cairns, Stephen D..

CAIRNS, S. D., 2000. A revision of the shallow-water azooxanthellate Scleractinia of the western Atlantic. Studies Nat. Hist. Caribbean Region 75, Amsterdam, 2000: 1-231. This paper constitutes the second of a two part revision of the western Atlantic azooxanthellate Scleractinia — this part addressing the taxonomy and distribution of the 73 species known to occur at depths shallower than 183 m within the tropical and warm temperate realm. Of this number, 27 species occur exclusively shallower than 183 m; these are fully described, figured, and mapped. The remaining 46 species are also known to occur at depths greater than 183 m, most of those species treated more fully in part 1 (CAIRNS 1979). Lists are also provided of the azooxanthellate species that...

Lemmens, J.W.T.J..

The scleractinian fauna of the Watamu Marine National Reserve, Kenya, was surveyed between November 1982 and April 1983. The survey yielded 276 specimens representing 113 species in 45 genera, which are presented in an annotated checklist. Four genera and 43 species are added to the the list of previously known Scleractinia for East-Africa, bringing the number of species recorded for this region to 169. This substantial increase, as well as the high coral diversity of nearby communities, suggests that further additions can be expected.

A lectotype has been assigned for Placosmilia? robusta Umbgrove, 1925. This taxon, although fitting into the original diagnosis of Placosmilia, is not defined by the emended diagnosis of Alloiteau and later authors. Specimens from the Upper Maastrichtian of The Netherlands, that were formerly wrongly attributed to Galaxea fasciculata (Lamarck, 1816), a homonym of the extant species Galaxea fascicularis (Linnaeus, 1758), belong to Placocoenia macrophthalma (Goldfuss, 1826). The specimen depicted as P. macrophthalma by Umbgrove does not belong to this taxon and is placed in open nomenclature.

Coral reefs in Jakarta Bay have been subjected to scientific studies since the 1920s. Also from that time on biological collections were made. The reefs in the Jakarta Bay have been under long-term natural and anthropogenic stress. With the biological collections and historical documents the coral species richness in Jakarta Bay around 1920 was reconstructed. New data from this bay and the adjacent offshore Thousand Islands archipelago were obtained during a 2005 research expedition. A comparison of the coral assemblages between 1920 and 2005 reveals a clear decline in species numbers. The most prominent results include the near-shore disappearance of species belonging to the families Acroporidae, Milleporidae, and to a lesser extent Poritidae. The overall...

A check-list of mushroom corals (Fungiidae) is given with annotations on their distribution in Madang Lagoon, northern Papua New Guinea, Bismarck Sea. A total of 36 fungiid species is recorded from this locality, which is more than from any other studied so far. One species, Cantharellus jebbi spec, nov., is new to science. It is the only monostomatous mushroom coral species known that is entirely encrusting. It also represents the first record of a recent Cantharellus species in the IndoMalayan region.

Mushroom corals of the Indo-West Pacific Fungiidae (Scleractinia) provide habitats for a rich associated fauna, including three species of gall crabs (Cryptochiridae). During the course of the present study gall crabs were sampled from many different fungiid hosts. Based on this ‘reversed’ approach - by studying coral symbionts from a host perspective - a previously unnoticed host specificity pattern was detected. The sampling of gall crab fauna per host coral combined with molecular analyses of H3 nDNA, 16S and COI mtDNA revealed a cryptic gall crab species closely related to Fungicola fagei. This new species, described hereafter as Fungicola syzygia sp. nov., is predominantly associated with the mushroom coral genera Cycloseris and Pleuractis, whereas...

Examination of about 60,000 scleractinian corals of the families Dendrophylliidae, Euphylliidae and Fungiidae for the presence of associated wentletrap snails (Gastropoda: Epitoniidae) revealed various ectoparasitic life history strategies. Twenty Indo-Pacific wentletrap species were found, which were either host-specific or generalist. Most species were associated with mushroom corals, especially free-living species belonging to the Fungiidae. Snails showed different preferences with regard to their position relative to mushroom corals, the host’s size and its substrate. No preferences for depth were found. Infestation rates of mushroom corals in multi-species assemblages were negatively correlated with coral densities, which indicates that epitoniid...

Three Indonesian species of Heterocyathus and two of Heteropsammia are briefly diagnosed. Remarks are given on their synonymy, phenotypic variation, and ecology. All five species are found on soft substrata in the proximity of coral reefs and live in association with a sipunculan worm. This interspecific assocation is discussed with regard to whether it is mutualistic or parasitic.

Nomina nova should be used only to denote replacement names for preoccupied names, i.e. in the case of homonymy. Three examples of incorrect applications of nomina nova in scleractinian taxonomy are given. Coincidentally, in the cases discussed each wrongly proposed nomen novum concerns a new species so that there are no nomenclatorial consequences. For one of these species, Galaxea paucisepta Claereboudt, 1990, a lectotype is designated.
