Modelling survival and connectivity of <i>Mnemiopsis leidyi</i> in the south-western North Sea and Scheldt estuaries
Three different models were applied to study the reproduction, survival and dispersal of <i>Mnemiopsis leidyi</i> in the Scheldt estuaries and the southern North Sea: a high-resolution particle tracking model with passive particles, a low-resolution particle tracking model with a reprodu...

| description | Three different models were applied to study the reproduction, survival and
dispersal of <i>Mnemiopsis leidyi</i> in the Scheldt estuaries and the southern North Sea: a
high-resolution particle tracking model with passive particles, a low-resolution particle tracking model with a reproduction model coupled to a
biogeochemical model, and a dynamic energy budget (DEB) model. The results of the
models, each with its strengths and weaknesses, suggest the following
conceptual situation: (i) the estuaries possess enough retention capability
to keep an overwintering population, and enough exchange with coastal waters
of the North Sea to seed offshore populations; (ii) <i>M. leidyi</i> can survive in the
North Sea, and be transported over considerable distances, thus facilitating
connectivity between coastal embayments; (iii) under current climatic
conditions, <i>M. leidyi</i> may not be able to reproduce in large numbers in coastal and
offshore waters of the North Sea, but this may change with global warming; however, this result is subject to substantial uncertainty. Further
quantitative observational work is needed on the effects of temperature,
salinity and food availability on reproduction and on mortality at different
life stages to improve models such as used here. |
