  abstract = {{T}he invasive ctenophore, {M}nemiopsis leidyi has been proliferating in lagoons and coastal areas around {E}urope for almost 20 years but the role and the impact of its presence in sink ecosystems is still not completely understood. {I}n {F}rance, {M}nemiopsis leidyi is present in {M}editerranean lagoons and estuaries along {L}a {M}anche {S}ea. {M}nemiopsis was first recorded in the {B}erre {L}agoon in early 2000. {T}his lagoon has been highly perturbated for years, with a large volume of freshwater inflow through natural rivers and a succession of large hydroelectric power plants, inducing important eutrophication. {L}egislation has been implemented to improve the health status of the lagoon since 1994. {A} long-term study was undertaken in 2010 to measure {M}nemiopsis population dynamics, and to identify the main drivers of its persistence in this highly anthropogenic lagoon. {I}n 2011 and 2012, during extreme winter conditions, populations of this ctenophore were not observed for months. {I}ts re-appearance later in year could be linked to either a new introduction from the {M}editerranean {S}ea or the existence of retention areas where individuals sought refugia. {F}ollowing measurement of biochemical conditions (i.e. chlorophyll a), plankton biomass and {M}nemiopsis populations structure (eggs, cydippid larvae/transitional phase and adult) in different areas of the lagoon, as well as the lagrangian modelling of "particles' distribution (i.e. {I}chthyop), we highlighted the seasonal patterns in the population structure, the level of available carbon always above the minimal for the survival of {M}nemiopsis (24 mu g{C} {L}-1) and the potential refugia area role the {V}aine sub-basin could play. {P}opulations from the {V}aine sub-basin probably serve as source populations for the rest of the lagoon by advective transport in spring.},
