Population dynamics of the ctenophore Mnemiopsis leidyi and its impact on the zooplankton in the coastal regions of the Black Sea of the Crimean coast in 2004–2008

Top-Down Impacts of Sea Nettles (Chrysaora quinquecirrha) on Pelagic Community Structure in Barnegat Bay, New Jersey, U.S.A.

“…He further surmised that unrestrained M. leidyi populations would increase until food resources are depleted and clearly, the significant top-down relationship we established between M. leidyi and their potential prey demonstrates their potential to structure the pelagic community (Figure 6b). It is this prolific reproduction potential coupled with high feeding rates that have led to significant changes in planktonic communities in regions that have seen invasions of M. leidyi (Finenko et al, 2013;Oguz et al, 2012;Roohi et al, 2010), but changes in native communities have also occurred, fueled by development, eutrophication, and hypoxia (Breitburg et al, 1997). Kimmel, Boynton, and Roman (2012) modeled the abundance of Acartia tonsa (Dana, 1849) in Chesapeake Bay.…”

“…In all of these systems, human influences relating to eutrophication and overfishing have fueled the degradation of these communities, thus altering food webs (Finenko et al, 2013;Llope et al, 2011). Consequently, M. leidyi introductions have demonstrated this species' ability to significantly affect pelagic food webs, devastate fisheries, and alter community structure through invasions and expansions.…”

“…It is now recognized that the expansion and continuation of gelatinous zooplankton blooms have the potential to significantly affect communities and under introduction to nonnative systems, their potential to permanently disrupt natural food webs has been demonstrated (Oguz et al, 2012). Concurrently, the long-term impacts to commercially important fisheries species is occurring through direct consumption of fish eggs, larvae, and juveniles (Finenko et al, 2013). Additionally, indirect impacts are occurring through competitive interactions for planktonic food resources with these same life-history stages (Purcell et al, 2001).…”

“…1) an emergent model system in which to study animal evolution and development (Pang & Martindale 2008a). In addition, since the invasion of M. leidyi into European waters from its native range on the Atlantic seaboard (Vinogradov et al 1989;Reusch et al 2010) has had profound impacts on European fisheries (Kideys 2002;Oguz, Fach & Salihoglu 2008;Finenko et al 2013), interest is high in the biogeography and invasion dynamics of M. leidyi. Despite the growing importance and utility of M. leidyi, the reproductive ecology of these animals is not very well understood.…”
