TL;DR: Depth of occurrence was found to predict local coral distributions but was not applicable to other regions, and factors which are discussed in relation to coral distributions include: coral mobility, coral shape, the effect of an obligate sipunculan associate, Aspidosiphon jukesii, in Heteropsammia cochlea and Heterocyathus aequicostatus, and settlement requirements.
Abstract: in 1974, 8 free-living coral species were found to inhabit the sandy sea floor adjacent to Lizard Island, Great Barrier Reef (14°40′S; 145°78′E). They fall into two groups which colonize two dissimilar sediment types. Plant cover increases with depth and, because of its effect on sediment characteristics, is thought to be a significant factor affecting coral distributions. The shallower coarse to medium grain sediments (0.5 to 0.125 mm) are mainly colonized by Heteropsammia cochlea, Heterocyathus aequicostatus, Diaseris distorta, and to a lesser extent by Cycloseris cyclolites. The deeper sediments are made up of a biogenically derived coarse fraction (larger than 0.5 mm) combined with an equally high proportion of fine-grade material. Corals typically found on these sediments are: Trachyphyllia geoffroyi, Catalaphyllia jardinei, Cynarina lacrymalis, and Cycloseris patelliformis. The content of non-carbonate material in the sediments reflects the hydrodynamics of the area and hence the degree of sedimentation, i.e., traction, saltation, or suspension loads, the corals have to cope with. Depth of occurrence was found to predict local coral distributions but was not applicable to other regions. Other factors which are discussed in relation to coral distributions include: coral mobility, coral shape, the effect of an obligate sipunculan associate, Aspidosiphon jukesii, in Heteropsammia cochlea and Heterocyathus aequicostatus, and settlement requirements.

TL;DR: Phylogenetic trees and haplotype network analyses show that S. margariticola belongs to the family Lobophylliidae and that it is closely related to Acanthastrea maxima, an uncommon species from waters around the Arabian peninsula, and moves A. maxima into Sclerophyllia.
Abstract: The monospecific scleractinian coral genus Sclerophyllia Klunzinger, 1879 was originally described from Al-Qusayr (Egypt) in the Red Sea based on a series of solitary specimens. Thenceforth, it has been considered a junior synonym of Symphyllia and Cynarina based on corallum macromorphology. In this study, several specimens of Sclerophyllia margariticola were collected on the coasts of Saudi Arabia in the northern and central Red Sea. Four molecular markers were sequenced, COI and the intergenic spacer between COI and l-rRNA from mitochondrial DNA and Histone H3 and ribosomal ITS2 from nuclear DNA. Phylogenetic trees and haplotype network analyses show that S. margariticola belongs to the family Lobophylliidae and that it is closely related to Acanthastrea maxima, an uncommon species from waters around the Arabian peninsula (the Gulf of Aden, Arabian Sea, Gulf of Oman and Persian Gulf). Sclerophyllia margariticola and A. maxima share several macro- and micromorphological characters, such as the presence o...

TL;DR: The coral recruitment in Hari Island showed that there was potential coral recovery in the island and the entire coral recruitment was dominated by genus Pocillopora reaching 80.0%.
Abstract: Study on coral recruitment in artificial reefs was carried out in Hari Island, Southeast Sulawesi. Data collection was conducted by calculating the number of genus colony and measuring coral size using visual census method equipped with scuba diving and an underwater camera. The construction of artificial reefs would vertically expand the profile of the survival of juvenile coral recruitment, where 95 new colonies of the recruitment had successfully been observed. Moreover, there were 10 genus of stony coral (Scleractinia) managed to be identified with the abundance proportion of Pocillopora, Acropora, Fungis, Leptoseris, Cynarina, Seriotopora, Acanthastrea, Favites, Montipora, Oxypora. The entire coral recruitment was dominated by genus Pocillopora reaching 80.0%. The coral recruitment in artificial reefs showed that there was potential coral recovery in the island.

TL;DR: The result showed that both of these coral cannot differentiate based on morphometric measurement, but it can differentiate significantly based on descriptive characters, so both ofThese coral are not synonym.
Abstract: Acanthophyllia deshayesiana has a different habitat with Cynarina lacrymalis in the nature, but they have same character on living forms, diameter, and height of corallite. Both of these species are considered synonym, thus it needs verification study to describe whether it is synonym species or not based on morphological data. Eleven descriptive characters and seven morphometric characters were used to verify the synonym species of these coral. Descriptive data were performed by scoring method, while morphometric data were obtained from morphometric. Morphometric data were analyzed by Correspondence Analysis of Principal Coordinates (CAP) and Agglomerative Hierarchical Cluster (AHC), while descriptive data were analyzed by UPGMA (Unweight Pair Group Method with Arithmetic Mean). The result showed that both of these coral cannot differentiate based on morphometric measurement. It can differentiate significantly based on descriptive characters, so both of these coral are not synonym.
