“…In the haplotype network (Fig. 2) it can be seen that all samples correspond to allele 8 (A8) of SRP54 and haplotype 18 (H18) of the concatenated ND2-ND6 segment, as described by Concepcion et al (2010) and Quintanilla et al (2017).…”

“…Non-rooted networks of haplotypes based on the 95% parsimony were constructed separately for mitochondrial and nuclear markers using TCS1.21 (Clement et al, 2000) with the nal manipulation in tcsBU (Santos et al, 2016). For the nDNA data, gaps were treated as a 5th state as in Quintanilla et al (2017).…”

The snowflake coral Carijoa riisei is one of the most invasive and successfully adapting species in the coastal marine environment. This species can disperse through ballast waters or fouling on the hull of ships, which allows it to expand very quickly to areas where it is not native. Recently C. riisei was identified in the Porto Grande Bay in São Vicente island in Cabo Verde Islands. We analysed mitochondrial and nuclear DNA sequences from specimens collected at this locality to determine the potential origin of this invasion. Lack of genetic variation in both mitochondrial and nuclear genes suggest a very recent invasion (bottleneck effect) but did not permit to establish its origin with total confidence.

“…In the Eastern Pacific, Carijoa grows on gorgonians instead of the black corals it grows on in Hawai'i (Antipathes griggi and A. grandis). Another genetic study explored the origin of these octocorals and indicated that these Eastern Pacific populations had close affinities to Western Atlantic populations suggesting they arrived into the Eastern Pacific relatively recently, probably by ship through the Panama Canal (Quintanilla et al 2017). The rise of notoriety of C. riisei in the Hawaiian Islands specifically was based on the species ability to overgrow native black coral colonies (Grigg 2003).…”

A review of the diversity and impact of invasive non-native species in tropical marine ecosystems

Tropical marine ecosystems are biologically diverse and economically invaluable. However, they are severely threatened from impacts associated with climate change coupled with localized and regional stressors, such as pollution and overfishing. Non-native species (sometimes referred to as ‘alien’ species) are another major threat facing these ecosystems, although rarely discussed and overshadowed by the other stressors mentioned above. NNS can be introduced accidentally (for example via shipping activities) and/or sometimes intentionally (for aquaculture or by hobbyists). Understanding the extent of the impacts NNS have on native flora and fauna often remains challenging, along with ascertaining when the species in question actually became ‘invasive’. Here we review the status of this threat across key tropical marine ecosystems such as coral reefs, algae meadows, mangroves, and seagrass beds. We aim to provide a baseline of where invasive NNS can be found, when they are thought to have been introduced and what impact they are thought to be having on the native ecosystems they now inhabit. In the appended material we provide a comprehensive list of NNS covering key groups such as macroalgae, sponges, seagrasses and mangroves, anthozoans, bryozoans, ascidians, fishes, and crustaceans.

“…The Indo-Pacific reports include Chuuk, Palau, the Philippines, Indonesia, Australia, Singapore, Shanghai, Sumatra, Manila, and New Britain (Raghunathan et al 2013). Finally, recent evidence indicate that C. riisei has spread widely in in the southern Eastern Pacific and might have been introduced from the Atlantic into the Colombian Tropical Eastern Pacific, possibly via the Panama Canal (Quintanilla et al 2017). According to genetic studies, the introduction of this octocoral species to the Hawaiian Islands occurred from the Indo-Pacific, separately from its arrival to the Caribbean (Concepcion et al 2010).…”

One colony of the snowflake coral Carijoa riisei (Alcyonacea: Clavulariidae) was found in June 2016, and three more in January 2017, during dives in the port of Manzanillo, Colima, Mexico (Tropical Eastern Pacific). This species was considered as native to the tropical Western Atlantic and invasive in the Pacific, but recent studies suggest that it is native to the Indo-West Pacific. Colonies were found and collected from artificial substrates in the port. A total of 29 species of invertebrates of five different phyla were associated with the colonies of C. riisei. Moreover, the octocoral was found as an epibiont on the architect crab Pelia tumida. Our observations suggest that the invasion of C. riisei in Manzanillo is in an early stage and that on-going monitoring and implementation of an eradication plan is necessary before its distribution is increased.
