  abstract = {{A}urelia aurita ({L}inneaus, 1758) is a cosmopolitan scyphozoan, probably the most investigated jellyfish in temperate and highly productive coastal ecosystems. {D}espite a prominent top-down control in plankton food webs, a mechanistic understanding of {A}. aurita population dynamics and trophic interactions has been barely addressed. {H}ere we develop a food web dynamic model to assess {A}. aurita role in the seasonal plankton dynamics of the {K}iel {F}jord, southwestern {B}altic {S}ea. {T}he model couples low trophic level dynamics, based on a classical {N}utrient {P}hytoplankton {Z}ooplankton {D}etritus ({NPZD}) model, to a stage-resolved copepod model (referencing {P}seudocalanus sp.) and a jellyfish model ({A}. aurita ephyra and medusa) as consumers and predators, respectively. {S}imulations showed the relevance of high abundances of {A}. aurita, which appear related with warm winter temperatures, promoting a shift from a copepod-dominated food web to a ciliate and medusa dominated one. {T}he model captured the intraspecific competition triggered by the medusae abundance and characterized by a negative relationship between population density and individual size/weight. {O}ur results provide a mechanistic understanding of an emergent trait such as size shaping the food web functioning, driving predation rates and population dynamics of {A}. aurita, driving its sexual reproductive strategy at the end of the pelagic phase.},
