“…The obtained sequences were aligned with a sequence of Siderastrea stellata (Forsman et al 2005) using ClustalW (Thompson et al 1994) as implemented in the software BioEdit version 7.0.9 (Hall 1999) to delimit the ITS1, 5.8S and ITS2 regions. The best fit model of nucleotide substitution was calculated by performing hierarchical likelihood ratio tests with Modeltest version 3.06 (Posada and Crandall 1998), and considered in subsequent analyses.…”

Genetic structure of Heliofungia actiniformis (Scleractinia: Fungiidae) populations in the Indo-Malay Archipelago: implications for live coral trade management efforts

et al. 2008

The fungiid Heliofungia actiniformis is one of the most popular scleractinian coral species in the growing live aquarium trade, with the majority of specimens originating in Indonesia. Details on population connectivity may potentially provide important information with regards to harvest management efforts. Genetic structure was examined, using ribosomal ITS1, 5.8S and partial ITS2 sequences on a small scale among populations in the Spermonde Archipelago, South Sulawesi (up to 65 km distance, U st = 0.09), and on a large scale throughout the Indo-Malay Archipelago (up to 2,900 km distance, U st = 0.26). Significant genetic structuring was found at both scales. Within the Spermonde Archipelago isolation by distance as well as local oceanographic features shaped patterns of genetic connectivity. On the large scale, the data revealed genetically distinct populations in Tomini Bay, New Guinea and the Thousand Islands near Jakarta, and a lack of genetic differentiation among populations lying close to or directly in the path of the Indonesian throughflow: from the central Visayas to the Flores Sea (U ct = 0.32). Whilst the influence of both historical and present day processes on genetic structuring of H. actiniformis populations was revealed, large scale results further emphasised the importance of oceanographic dynamics on larval dispersal patterns in this species. Potential for larval input from surrounding populations, and the increased vulnerability of upstream as well as isolated populations should be taken into consideration when setting future harvest quotas.

The evolutionary history of the order Antipatharia (Cnidaria: Anthozoa: Hexacorallia) as inferred from mitochondrial and nuclear DNA: implications for black coral taxonomy and systematics

2013

Although black corals inhabit all the world's oceans, they have been relatively understudied as ∼185 of 247 species occur at depths > 50 m. Antipatharians have been included in several phylogenetic studies; however, sample sizes are small and taxonomic coverage minimal. Low levels of mitochondrial (mt) sequence divergence within Scleractinia and Octocorallia are assumed to apply to all anthozoans, although no formal study has been conducted on the order Antipatharia. To quantify genetic variation in the black coral mitogenome, we analysed DNA sequences of the two longest intergenic regions (IGRs) and cox3‐cox1 for 26 of 41 genera, representing all families and subfamilies. We also quantified divergence at the intraspecific level using six mtIGRs and their flanking protein‐coding genes and rRNA for 100+ colonies of Antipathes griggi. Utilizing sequence data from the two mtIGRs, cox3‐cox1, as well as nuclear 18S and 28S, we constructed the first multi‐locus phylogenies of the Antipatharia. Reconstructions revealed that species in the genus Stichopathes are split across two families, Sibopathes macrospina groups among North Atlantic Parantipathes (suggesting the actinopharynx and mesenteries were secondarily lost), and three families are polyphyletic. These and other results provide novel, independent insights into the evolutionary history of antipatharians and support placement of species into higher‐level groupings based on microscopic skeletal features rather than gross colony morphology. An illustrated key to the seven currently recognized families is also provided. © 2013 The Linnean Society of London

“…S. glynni is morphometrically most similar to S. savignyana , the only Indo‐Pacific species in the genus, and it has therefore been hypothesized that S. glynni has originated from a rare dispersal event from the central Pacific (Budd & Guzman 1994). rDNA ITS sequence analysis, however, rejects this theory and shows that the S. glynni population has most likely arisen from a recent introduction from the Caribbean (Forsman et al . 2005).…”

Conservation genetics and the resilience of reef‐building corals

Coral reefs have suffered long-term decline due to a range of anthropogenic disturbances and are now also under threat from climate change. For appropriate management of these vulnerable and valuable ecosystems it is important to understand the factors and processes that determine their resilience and that of the organisms inhabiting them, as well as those that have led to existing patterns of coral reef biodiversity. The scleractinian (stony) corals deposit the structural framework that supports and promotes the maintenance of biological diversity and complexity of coral reefs, and as such, are major components of these ecosystems. The success of reef-building corals is related to their obligate symbiotic association with dinoflagellates of the genus Symbiodinium. These one-celled algal symbionts (zooxanthellae) live in the endodermal tissues of their coral host, provide most of the host's energy budget and promote rapid calcification. Furthermore, zooxanthellae are the main primary producers on coral reefs due to the oligotrophic nature of the surrounding waters. In this review paper, we summarize and critically evaluate studies that have employed genetics and/or molecular biology in examining questions relating to the evolution and ecology of reef-building corals and their algal endosymbionts, and that bear relevance to coral reef conservation. We discuss how these studies can focus future efforts, and examine how these approaches enhance our understanding of the resilience of reef-building corals.
