“…Since then, high densities have been noted in Limfjorden (Denmark, 867 ind m À3 ; Riisgård et al, 2007) and the Wadden Sea (The Netherlands, 610 ind m À3 ; van Walraven et al, 2013). Hitherto, M. leidyi has been observed from the English Channel (Antajan et al, 2014) and the Southern North Sea (Van Ginderdeuren et al, 2012;van Walraven et al, 2013) up to the German Bight and Danish territorial waters (Boersma et al, 2007;Javidpour et al, 2009a;Riisgård et al, 2012). It has not yet been encountered along the UK coasts (Antajan et al, unpublished data;Collingridge et al, 2014).…”

“…By the 2000s, M. leidyi spanned the entirety of the Mediterranean Sea (Fuentes et al 2009;Boero et al 2009;Galil et al 2009;Shiganova and Malej 2009;Fuentes et al 2010). It was first found in northern Europe in 2006, both in the North Sea (Faasse and Bayha 2006;Hansson 2006;Boersma et al 2007) and the Baltic Sea (Javidpour et al 2006), subsequently spreading to other areas of both seas, as well as adjacent water bodies (Oliveira 2007;Tendal et al 2007;Janas and Zgrundo 2007;Van Ginderdeuren et al 2012;Antajan et al 2014).…”

Worldwide phylogeography of the invasive ctenophore Mnemiopsis leidyi (Ctenophora) based on nuclear and mitochondrial DNA data

The ctenophore Mnemiopsis leidyi is one of the most successful marine bioinvaders on record. Native to the Atlantic coast of the Americas, M. leidyi invaded the Black Sea, Caspian and Mediterranean Seas beginning the in late 1980s, followed by the North and Baltic Seas starting in 2006, with major concomitant alterations in pelagic ecology, including fishery collapses in some cases. Using extensive native range sampling (21 sites), along with 11 invasive sites in the Black, Caspian, Mediterranean, North and Baltic Seas, we examined M. leidyi worldwide phylogeographic patterns using data from mitochondrial cytochrome b (cytb) and six nuclear microsatellite loci. Cytb and microsatellite data sets showed different levels of genetic differentiation in the native range. Analyses of cytb data revealed considerable genetic differentiation, recovering three major clusters (northwestern Atlantic, Caribbean, and South America) and further divided northwestern Atlantic sampling sites into three groups, separated approximately at Cape Hatteras on the US Atlantic coast and at the Floridian peninsula, separating the Gulf of Mexico and Atlantic coasts. In contrast, microsatellite data only distinguished samples north and south of Cape Hatteras, and suggested considerable gene flow among native samples with clear evidence of isolation by distance.

“…Both the northward and westward distribution limits in the North Sea are currently not well defined and subject to ongoing research, with the most recent reports from the Belgian coast (Van Ginderdeuren et al 2012). In the Baltic the eastward distribution limit has been indentified as the Bornholm Basin (Gorokhova et al 2009, Reusch et al 2010, Schaber et al 2011.…”

Repeated invasions of European waters by the ctenophore Mnemiopsis leidyi offer a unique opportunity to study population dynamics and dispersal in gelatinous zooplankton. Here we followed population establishment in 2 recently invaded areas, the North and Baltic Seas, and analysed changes in population structure during a 3 yr interval using 7 highly polymorphic microsatellites comprising 191 alleles. A second goal was to reconstruct routes of recent invasive range expansion into the Mediterranean Sea. During the study period (2008 to 2010), populations in the North Sea and Western Baltic Sea maintained their allelic composition with virtually unchanged levels of genetic diversity and between-population differentiation, demonstrating limited gene flow between the 2 regions and successful reproduction in both areas. In contrast, at the eastern distribution limit in the central Baltic (Bornholm Basin), the same measures fluctuated between years and genetic diversity decreased from 2008 to 2010. In concordance with prior ecological observations, this supports the view that M. leidyi in the central Baltic is a sink population. In the area of recent range expansion (Mediterranean Sea), we observed high population differentiation: pairwise differentiation (F ST ) values between sites in Spain, France and Israel were significant and between 0.04 and 0.16. Despite this differentiation, Bayesian clustering and phylogeographic analysis support the hypothesis that all Mediterranean M. leidyi result from a secondary introduction originating from the Black Sea. Our study contributes to growing evidence that multiple invasions of the same species can vary in their degree of genetic diversity and demonstrates how genetic markers can help to resolve whether gelatinous plankton species form self-sustaining populations.
