“…Yet localized regions of high coral abundance exist that may support cold-water coral recolonization. Genetic and phylogeographic analysis of deep-water corals in the NE Atlantic (Le GoV-Vitry et al 2004;Le GoV-Vitry and Rogers 2005) suggest that Lophelia pertusa does not form a panmictic population. Instead, there is a high genetic diVerentiation between subpopulations in fjords and those oVshore.…”

“…This is of particular concern considering the low genetic diVerentiation of deep-water corals subpopulations along the NE Atlantic continental margin (Le GoV-Vitry et al 2004;Le GoV-Vitry and Rogers 2005), suggesting a sporadic gene Xow through larval dispersal over long periods of time. At a time where bottom Wshing damage continues partly because coral-rich areas remain poorly mapped, it is essential to identify the potential and the importance of this region for the long-term protection of the European continental slopes.…”

Studies on the distribution of scleractinian corals in the Bay of Biscay were relatively numerous during the nineteenth and the Wrst 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 Yet, recent reports are scattered, sometimes unpublished, and therefore knowledge about the current coral occurrence in the area is limited.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 be expected due to the high topographic relief providing the necessary hard substrate and accelerated bottom current Xow that corals require. Further exploration of the occurrence and ecology of corals in the area is recommended to support the conservation of cold-water coral reefs along the European margin.

Population genetics of Narella versluysi (Octocorallia: Alcyonacea, Primnoidae) in the Bay of Biscay (NE Atlantic)

Octocoral species are globally distributed in all oceans and may form dense communities known as vulnerable marine ecosystems. Despite their importance as deep-water habitats , the underlying genetic structure and gene-flow patterns of most deep-water populations remains largely unknown. Here, we evaluated genetic connectivity of the primnoid octocoral Narella versluysi across the continental shelf of Bay of Biscay, spanning 360 km (95 samples from submarine canyons, ranging from 709-1247 m depths). We report 12 novel microsatellite markers which were used to genotype 83 samples from six populations. Sixteen samples were sequenced for three mitochondrial DNA regions (Folmer region of COI with an adjacent intergenic region igr1, MT-ND2 gene, and mtMutS homolog 1 region). All sequence haplotypes and genetic clusters were found in multiple sites spanning more than 200 km. Overall, our analyses suggest there is high gene flow between colonies of N. versluysi among all study sites. There is no significant geographic 2 structure and no pattern of isolation by distance or depth. Connectivity is facilitated by the prevailing current which runs along the shelf break, and could be a mechanism to connect all of the sampled locations. The high connectivity over large geographic distance is a positive sign for a potentially vulnerable organism and may provide some resilience to disturbance. This information is crucial for a better understanding of how this fragile benthic fauna may respond to climatic and anthropogenic disturbances, which is a cornerstone for effective habitat management.

“…used different criteria in the same areas. The studies demonstrated the distribution of endangered species, genetic isolation, human impact, genetic connectivity, and discontinuity(Le Goff-Vitry and Rogers, 2005;Miller et al, 2008;Magalon et al, 2011;Morrison et al, 2011;Ross et al, 2017).Genetic evaluation was performed via phylogenetic tree construction using mitochondrial 16S DNA and intraspecific analyses of diversity and connectivity that involved microsatellite markers(Le Goff-Vitry and Rogers, 2005;Morrison et al, 2011;Ross et al, 2017). Although most analyses were populationbased, two focused on invertebrate communities.…”

Consideration of Genetic Structure in the Ecologically or Biologically Significant Marine Areas Criteria: A Review of Convention on Biological Diversity Regional Workshops and A Case Study of Coral Reef Conservation Planning

et al. 2022

In this study we reviewed the use of genetic information in the Ecologically or Biologically Significant Marine Areas (EBSA) of Convention on Biological Diversity (CBD). We also evaluated genetic indicators for each criterion of important marine areas. We proposed five genetic indices, mainly based on microsatellite analysis (e.g., private allele frequency and number of cryptic species), then selected EBSAs in tropical and temperate zones of Japan based on eight coral species as a case study. Finally, we compared the results with the findings from conventional species-based EBSAs. In the EBSAs genetic information was mainly used in the Northern Hemisphere, particularly in the Baltic Sea; it was rarely applied in the Southern Hemisphere and Asian regions. Although typically applied to large organisms, genetic information is used to various organisms, including benthic and bacterial communities. Genetic data are used as indicators of diversity and endemism. Genetic indices were available for all seven EBSA criteria, but only five indices of three criteria were used. Examination of important areas of corals in the temperate zone using these indices showed that the indices without genetic indicators extracted a large number of important areas in the tropics; however, the use of genetic indicators identified important locations, including in temperate zones. Comparison with conventional, mainly species-based non-genetic methods showed less than 50% agreement, although particularly important sites in marine protected areas were identified by both methods. While there is still more work to be done, such as consideration of the number of survey sites or target species, one reason is that species-based methods tend to evaluate tropical areas higher. Therefore, these genetic indices are useful for examining important regions, particularly in temperate zones; they revealed cryptic lineages, indicating that many unknown marine taxa should be considered in vulnerable marine areas. Some indicators could be extracted with additional effort, such as population size estimation, immigration, or the use of next-generation sequencing, thus guiding future studies. Because limited genetic information was available in the early stages of EBSA selection, there is a need for systematic surveys and evaluations, particularly in the Southern hemisphere, Asian region, and in small organisms.
