“…Specimens records were organised and plotted in ArcGIS 10.6 to visualise the geographical distribution and a depth plot was prepared to visualise the vertical distribution of the gorgonians. This data was compared with previous zoogeographical and bathymetrical distribution knowledge on Plexauridae species of the NE Atlantic (e.g., Studer 1901; Thomson 1927; Tixier-Durivault and D´Hondt 1974; Carpine and Grasshoff 1975, 1985; Grasshoff 1977, 1986, 1989; Brito and Ocaña 2004). New species records were analysed by region as well as new geographical and vertical distribution records.…”

Mapping biodiversity is the marathon of the 21st Century as an answer to the present extinction crisis. A century in which science is also characterised by large scientific datasets collected through new technologies aiming to fill gaps in our knowledge of species distributions. However, most species records rely on observations that are not linked to specimens, which does not allow verification of species hypotheses by other scientists. Natural history museums form a verifiable source of biodiversity records which were made by taxonomists. Nonetheless, these museums seem to be forgotten by biologists in scientific fields other than taxonomy or systematics. Naturalis Biodiversity Center (NBC) in Leiden is care keeper of large collections of marine organisms, which were sampled in the Northeast Atlantic during the CANCAP and Tyro Mauritania II expeditions (1976–1988). Many octocorals were sampled and deposited in the NBC collection, where they became available for study and were partially identified by the senior author (M.G.) in the 1980s. Nonetheless, no checklist or taxonomic revision was published so far with the complete results. In 2016 the first author visited NBC to examine NE Atlantic Plexauridae octocorals. Plexauridae octocoral-vouchered records were listed and mapped to reveal high standard primary biodiversity records unreported so far for the NE Atlantic Ocean. Twenty-four Plexauridae species with ~ six putative new species to science were discovered and eleven new biogeographical records were made from distinct Macaronesian archipelagos. Finally, new depth range records were found for three species at sea basin level and for eight species at a regional scale.

“…The arrival of NIS at the Canary Islands has increased dramatically since 2011, when the traffic of oil rigs and digging vessels rose, particularly at Gran Canaria and Tenerife Islands. Certain NIS that are considered invasive have been recorded since then, including the corals Oculina patagonica and Tubastraea coccinea (Brito et al 2017) and the portunid crab Cronius ruber (González et al 2017). Similarly, the observation of dozens of tropical fish species in the vicinity of industrial ports in Gran Canaria, particularly around the industrial port of Las Palmas, has been linked to the maritime routes of oil rigs (Brito et al 2011, Triay-Portella et al 2015, Pajuelo et al 2016.…”

Widespread demographic explosion of a non-indigenous hydrozoan on an oceanic island

The arrival of non-indigenous species into new areas is one of the main processes altering the oceans globally. Macrorhynchia philippina is a large-sized colonial hydrozoan of an invasive nature. To obtain a deeper understanding of the process of colonization of new areas, it is essential to describe the ecological pattern through scales of temporal and spatial variation. In this study, we describe the colonization by M. Philippina of an oceanic island (Gran Canaria Island, Canary Islands, eastern Atlantic). We describe the abundance and size structure patterns of M. Philippina in three nearshore habitats, rocky reefs, seagrass meadows and rhodolith seabeds, at times before (2014), during (2016) and after (2017) the demographic explosion of this species. On rocky reefs and rhodolith seabeds, the abundance of colonies increased dramatically in 2017 relative to 2014, e.g. from 0 to 138 colonies/100 m2. On seagrass meadows, however, the colonies were smaller. In summary, M. Philippina shows an ecological plasticity to rapidly colonize different types of nearshore habitats, but with varying success.

“…Invasive Tubastraea corals are found in the Caribbean Sea, the Gulf of Mexico and have been detected discontinuously along 3850 km of the coast of Brazil (from 2°30’S to 26°30’S) [20,22–28] occupying up to 95% of the available substrate in some regions [12]. Recently Tubastraea corals were found around Eastern Atlantic islands including the Canary Islands [29,30] and Cape Verde [31]. Without innovation in control methods, dispersion is expected to continue, as desiccation in drydocks and physical removal cannot be applied in a timely and cost-effective manner, or risks inadvertently contributing to further dispersion.…”

Corals have been attracting huge attention due to the impact of climate change and ocean acidification on reef formation and resilience. Nevertheless, some coral species have been spreading very fast, replacing native species and affecting local biodiversity. Despite some focal efforts to understand the biology of these organisms, they remain understudied at the molecular level. This knowledge gap hinders the development of cost-effective strategies for management of invasive species. Here, we present the first Tubastraea sp. genome in one of the most comprehensive biological studies of a coral, that includes morphology, flow cytometry, karyotyping, transcriptomics, genomics, and phylogeny. The Tubastraea sp. genome is organized in 23 chromosome pairs and has 1.4 Gb making it the largest coral and Cnidaria genome sequenced to date. The hybrid assembly using short and long-reads has a N50 of 180,044 pb, 12,320 contigs and high completeness estimated as 91.6% of BUSCO complete genes. We inferred that almost half of the genome consists of repetitive elements, mostly interspersed repeats. Gene content was estimated as about 94,000, a high number that warrants deeper scrutiny. The Tubastraea sp. genome is a fundamental study which promises to provide insights not only about the genetic basis for the extreme invasiveness of this particular coral species, but to understand the adaptation flaws of some reef corals in the face of anthropic-induced environmental disturbances. We expect the data generated in this study will foster the development of efficient technologies for the management of corals species, whether invasive or threatened.
