“…For example, the absence of predators and competitors for the alien ctenophore Mnemiopsis in the Black Sea, contrary to in its native habitat, had severe impacts on the Black Sea ecosystem in the late 1980s and early 1990s. The reduction in zooplanktivorous fish populations in the Black Sea due to overfishing prior to the ctenophore outbreak, combined with predation by Mnemiopsis on fish eggs, contributed to the success of Mnemiopsis in the Black Sea and subsequent reductions in fish populations (Purcell et al 2001). The appearance of yet another invasive ctenophore (Beroe) Á that preyed on Mnemiopsis Á promoted recovery of the Black Sea ecosystem from effects of the Mnemiopsis invasion .…”

Spatial and bathymetric distribution, population density, habitat preferences, fecundity, breeding season and interspecific interactions of the alien grapsoid crab Percnon gibbesi (H. Milne-Edwards, 1853) from the Maltese Islands (Malta and Gozo) are compared among localities in the Mediterranean where established populations have been reported since 1999. In the Maltese Islands, habitat preferences and bathymetric distribution were similar to those in other Mediterranean localities. Spatial distribution was found to be limited by the availability of the boulder habitat in which this crab nearly always occurs. Fecundity was higher in the Maltese Islands than in Linosa and Lampedusa, the breeding season lasting from the end of May until September. On Maltese shores the habitat of the alien overlapped with that of the native grapsid Pachygrapsus marmoratus (Fabricius, 1787) (Crustacea: Brachyura: Grapsoidea) and, to a lesser extent, that of the native xanthid Eriphia verrucosa (Forskål, 1775). Laboratory studies to assess the possible interactions of the alien species with P. marmoratus suggest that the latter shows a competitive advantage over P. gibbesi, since 80.8% of encounters between the two species were initiated by P. marmoratus, and in 80% of the encounters it prevailed. This suggests that P. marmoratus is unlikely to be excluded from its natural habitat by the alien species, and that significant spatial resource partitioning on the part of P. marmoratus is unlikely to occur.

“…M. leidyi populations may be dense both close to the bottom and the surface (Miller, 1974;Costello & Mianzan, 2003). Vertically heterogeneous distributions in nature may also be attributed to both passive downward mixing and active surface avoidance during periods of heavy wind mixing, because high turbulence supposedly interferes with maintenance of the feeding position (Miller, Purcell et al, 2001;Mianzan et al, 2010). Also, M. leidyi tolerates hypoxia well (Thuesen et al, 2005) and may utilize poorly oxygenated deep water layers for spatial refuge (Decker et al, 2004).…”

“…In particular, ctenophores in the genus Beroe feed on many ctenophores (reviewed in Purcell, 1991). Population control on various ctenophore species have been implicated from field studies in the northwestern Atlantic Ocean (Beroe ovata Bruguière, 1789; in Swanberg, 1974;Purcell et al, 2001), the Black Sea (B. ovata; in Stone, 2005;Vinogradov et al, 2005), Norwegian coastal waters (Beroe cucumis Fabricius, 1780; in Falkenhaug, 1996), and the North Sea (Beroe gracilis Künne, 1939;in Greve & Reiners, 1988).…”

Predator-induced vertical behavior of a ctenophore

et al. 2012

Although many studies have focused on Mnemiopsis leidyi predation, little is known about the role of this ctenophore as prey when abundant in native and invaded pelagic systems. We examined the response of the ctenophore M. leidyi to the predatory ctenophore Beroe ovata in an experiment in which the two species could potentially sense each other while being physically separated. On average, M. leidyi responded to the predator's presence by increasing variability in swimming speeds and by lowering their vertical distribution. Such behavior may help explain field records of vertical migration, as well as stratified and near-bottom distributions of M. leidyi.

“…Genetic studies suggest that while the southern European invaders stem from the Gulf of Mexico region, the invaders to northern Europe originate from the coast of New England (Reusch et al, 2010) and could thus be expected to be better adapted to the North East Atlantic climatic conditions. Mnemiopsis leidyi tolerates a wide range of salinities and temperatures,~0 -328C and ,2-39 PSU (Purcell et al, 2001;Costello et al, 2012). Egg production of M. leidyi from Gullmarsfjorden, Sweden, increases with salinity (range 6-33), with the highest reproductive rates observed at salinities of 25 and 33, and salinity ,10 compromising reproduction (Jaspers et al, 2011).…”

“…These include a wide tolerance for environmental conditions such as temperature, salinity and dissolved oxygen, opportunistic feeding with dietary flexibility and high potential ingestion rates, as well as the potential for rapid population increases due to high fecundity, short generation times and the capacity for self-fertilization (reviewed in Purcell et al, 2001;Costello et al, 2012). Abundant M. leidyi can have a considerable predatory impact on mesozooplankton populations (Granhag et al, 2011), with the subsequent cascading effects on the rest of the ecosystem potentially resulting in socio-economic problems, as evidenced by experiences from the Ponto-Caspian region (Knowler, 2005).…”

We present data on the occurrence of the invasive ctenophore Mnemiopsis leidyi in Norway after the initial observations made in 2005. Our data comes from several net sampling investigations conducted along the Norwegian coast in 2008-2014, as well as beach seine bycatch from the south coast (September -October 2005. In 2008-2010, M. leidyi occurred in moderate abundances (≤0.56 lobate ind m 23 ) during autumn, with northernmost observations from Trondheimsfjord. Mnemiopsis leidyi was not observed in 2011 -2012 and was scarce in 2013, but in 2014 it was again abundant along the south and west coasts. While temperature and salinity conditions along the Norwegian south coast and its fjords are sufficient for survival and reproduction by M. leidyi, temperature may limit egg production rates. Biological factors including food limitation as well as competition and predation by native gelatinous predators can also constrain populations. Mnemiopsis leidyi populations in Norway are likely to exhibit source-sink dynamics, with advective losses and suboptimal conditions preventing overwintering in large areas along the coast. The presence of M. leidyi in the southern North Sea, coupled with the cyclonic circulation pattern, suggests that outbreaks may nevertheless be expected in years with favourable conditions and/or significant inflow from the southern North Sea. Climate change could enhance reproduction of M. leidyi in Norway and protected inner fjords may offer a suitable habitat for establishment of local populations in the future.
