“…Mitochondrial data do not indicate any new introductions of genetic material since the first publication of mitochondrial population genetic data in 2009 (Freshwater et al, ). Also in line with previous studies, distributional patterns and haplotype relationships largely corresponded to those described in Butterfield et al, . For most locations, only two or three haplotypes were present in the tested sample, but all five haplotypes were found in the Bahamas samples.…”

“…No geographic metapopulation genetic structure was observed in either a PCA or fastSTRUCTURE analysis and only minor differences in F ST values were observed across nine populations in the Caribbean Sea. While mitochondrial data were consistent with previous genetic investigations concluding that a strong initial bottleneck was followed by mixing and that Caribbean currents may have helped to produce low levels of population differentiation in lionfish (Butterfield et al, ); the RAD‐sequencing results for population structure did not find evidence of a genetic break between sites previously designated as Atlantic sites (Florida and The Bahamas) and those in the Caribbean (the rest of our study sites). The PCA and F ST analyses of RAD‐seq data presented here, rather, indicate that there is no structure.…”

“…Mitochondrial haplotypes consisting of 679 bp of the mitochondrial control D‐loop region were sequenced for 217 samples. Only five of the nine known haplotypes previously described were identified in these samples (Betancur‐R et al, ; Butterfield et al, ; Freshwater et al, ). These haplotypes correspond to previously named haplotypes H01, H02, H03, H04, and H06.…”

“…To date, studies have identified just nine haplotypes of mitochondrial D‐loop in the invaded range but have not traced these directly back to a specific source in the native range, where genetic diversity is much greater (Betancur‐R et al, ; Butterfield et al, ; Freshwater et al, ; Johnson, Bird, Johnston, Fogg, & Hogan, ). While north‐to‐south (i.e., Western Atlantic to Caribbean) population differentiation has been reported in the invaded range, overall, a lack of metapopulation genetic structure has been reported within oceanic basins (Betancur‐R et al, ; Butterfield et al, ; Freshwater et al, ; Johnson et al, ; Toledo‐Hernández et al, ), with some local population structure reported in Puerto Rico (Toledo‐Hernández et al, ). Evidence of a bottleneck between the Caribbean and the Gulf of Mexico populations based on mitochondrial data has been presented based on the presence of only three of the four Caribbean D‐loop haplotypes in Gulf of Mexico populations (Johnson et al, ).…”

Population genomics of rapidly invading lionfish in the Caribbean reveals signals of range expansion in the absence of spatial population structure

Range expansions driven by global change and species invasions may have significant genomic, evolutionary, and ecological implications. During range expansions, strong genetic drift characterized by repeated founder events can result in decreased genetic diversity with increased distance from the center of the historic range, or the point of invasion. The invasion of the Indo‐Pacific lionfish, Pterois volitans, into waters off the US East Coast, Gulf of Mexico, and Caribbean Sea provides a natural system to study rapid range expansion in an invasive marine fish with high dispersal capabilities. We report results from 12,759 single nucleotide polymorphism loci sequenced by restriction enzyme‐associated DNA sequencing for nine P. volitans sampling areas in the invaded range, including Florida and other sites throughout the Caribbean, as well as mitochondrial control region D‐loop data. Analyses revealed low to no spatially explicit metapopulation genetic structure, which is partly consistent with previous finding of little structure within ocean basins, but partly divergent from initial reports of between‐basin structure. Genetic diversity, however, was not homogeneous across all sampled sites. Patterns of genetic diversity correlate with invasion pathway. Observed heterozygosity, averaged across all loci within a population, decreases with distance from Florida while expected heterozygosity is mostly constant in sampled populations, indicating population genetic disequilibrium correlated with distance from the point of invasion. Using an FST outlier analysis and a Bayesian environmental correlation analysis, we identified 256 and 616 loci, respectively, that could be experiencing selection or genetic drift. Of these, 24 loci were shared between the two methods.

“…Great strides have been made in understanding their ecology in the native range [Darling et al, ; Cure et al, , ; Kulbicki et al, ; Sikkel et al, ; Stevens & Olson, ; Pusack et al, ; Tuttle et al, ; Fig. (b)], how best to survey them (Green et al, ; Tilley et al, ; Bacheler et al, ), their movement patterns (Tamburello & Côté, ; Bacheler et al, ; Benkwitt, ) and their genetic structure (Hamner et al, ; Freshwater et al, ; Betancur‐R et al, ; Toledo‐Hernández et al, ; Butterfield et al, ; Johnson et al, ). There is also recent molecular evidence that P. volitans in the native range might in fact be a hybrid between two sister lineages (Indian Ocean P. miles x Pacific Ocean Pterois russelii Bennett 1831; Wilcox et al, ).…”

The lionfish Pterois sp. invasion: Has the worst‐case scenario come to pass?

This review revisits the traits thought to have contributed to the success of Indo-Pacific lionfish Pterois sp. as an invader in the western Atlantic Ocean and the worst-case scenario about their potential ecological effects in light of the more than 150 studies conducted in the past 5 years. Fast somatic growth, resistance to parasites, effective anti-predator defences and an ability to circumvent predator recognition mechanisms by prey have probably contributed to rapid population increases of lionfish in the invaded range. However, evidence that lionfish are strong competitors is still ambiguous, in part because demonstrating competition is challenging. Geographic spread has likely been facilitated by the remarkable capacity of lionfish for prolonged fasting in combination with other broad physiological tolerances. Lionfish have had a large detrimental effect on native reef-fish populations in the northern part of the invaded range, but similar effects have yet to be seen in the southern Caribbean. Most other envisaged direct and indirect consequences of lionfish predation and competition, even those that might have been expected to occur rapidly, such as shifts in benthic composition, have yet to be realized. Lionfish populations in some of the first areas invaded have started to decline, perhaps as a result of resource depletion or ongoing fishing and culling, so there is hope that these areas have already experienced the worst of the invasion. In closing, we place lionfish in a broader context and argue that it can serve as a new model to test some fundamental questions in invasion ecology.

Genetic connectivity of lionfish (Pterois volitans) in marine protected areas of the Gulf of Mexico and Caribbean Sea

Lionfish (Pterois volitans) have rapidly invaded the tropical Atlantic and spread across the wider Caribbean in a relatively short period of time. Because of its high invasion capacity, we used it as a model to identify the connectivity among nine marine protected areas (MPAs) situated in four countries in the Gulf of Mexico and the Caribbean Sea. This study provides evidence of local genetic differentiation of P. volitans in the Gulf of Mexico and the Caribbean Sea. A total of 475 lionfish samples were characterized with 12 microsatellites, with 6-20 alleles per locus. Departures from Hardy-Weinberg equilibrium (HWE) were found in 10 of the 12 loci, all caused by heterozygous excess. Moderate genetic differentiation was observed between Chiriviche, Venezuela and Xcalak, México localities (F ST = 0.012), and between the Los Roques and the Veracruz (F ST = 0.074) sites. STRUCTURE analysis found that four genetic entities best fit our data. A unique genetic group in the Gulf of Mexico may imply that the lionfish invasion unfolded both in a counterclockwise manner in the Gulf of Mexico. In spite of the notable dispersion of P. volitans, our results show some | 3845 GUZMÁN-MÉNDEZ Et al.
