  abstract = {{F}or many jellyfish, the magnitude and timing of medusae blooms are recognized to result from the benthic stage dynamics. {H}owever, information on the scyphistomae of jellyfish populations in the wild remains scarce. {H}ere, bi-mensual underwater photoquadrat surveys were combined with scyphistomae sampling and observation to describe the annual ({F}ebruary 2017-{J}anuary 2018) benthic stage dynamics and asexual reproduction strategy of {A}urelia coerulea in the {T}hau lagoon (43 degrees 2531.1{N}; 03 degrees 420.9{E}). {O}ur results revealed unexpected seasonal patterns of variation: scyphistoma coverage peaked in the spring (11.6 +/- 3.7% on 21st{A}pril) and was minimal in the summer and autumn (1.4 +/- 1.3% on 10th {O}ctober). {T}he increase in scyphistoma coverage mainly resulted from an intense production of buds between {F}ebruary and {A}pril during the spring rise in water temperature (peak of 12,800 buds m(-2) on 21st{A}pril), but scyphistoma coverage appeared to be negatively influenced by the interaction of high summer temperatures and salinities. {S}trobilation was observed from {N}ovember to {A}pril. {I}t peaked on 17th {N}ovember, with 33.1% of the scyphistomae strobilating and an average production of 19,100 strobila disks m(-2). {H}owever, the low scyphistoma coverage at this time of the year (<2%) likely limited the intensity of ephyrae liberation and the subsequent medusae bloom. {T}he final population size of {A}. coerulea thus results from a complex interaction of abiotic and biotic factors. {O}ur results bring into question how the different populations of {A}urelia spp. will respond to the predicted global warming scenarios.},
