Inductive effect of bioactive substances on strobilation of jellyfish Aurelia coerulea
Journal of Oceanology and Limnology, 2020The moon jellyfish Aurelia spp. is a worldwide distributed scyphozoan species that seasonally blooms in coastal waters. Although the strobilation is directly responsible for the scale of jellyfish bloom, the underlying mechanisms remain largely unknown.

Marine Environmental ResearchScyphozoan jellyfish, known for their evolutionary position and ecological significance, are thought to exhibit relatively notable resilience to ocean acidification. However, knowledge regarding the molecular mechanisms underlying the scyphozoan jellyfish response to acidified seawater conditions is currently lacking.

Effects of temperature and salinity on the asexual reproduction of Aurelia coerulea polyps
Journal of Oceanology and Limnology, 2019Aurelia coerulea polyp is an important stage in the outbreaks of this species. To test the combined effects of salinity and temperature on the survival and asexual reproduction of polyps, we maintained 864 polyps at various salinities (15, 25, 33, and 40) and temperatures (9, 12, 15, 18, 21, and 24°C).

Science of The Total Environment, 2023 Copper (Cu) is a trace element that is engaged in various routine physiological processes. Excessive copper exposure can cause damage to organisms; however, it is unknown if the mechanisms underlying the response to Cu2+ among different species are conserved.Aurelia coerulea polyps and mice models were exposed to Cu2+ to assess its effects on survival ...

Using nets and acoustic frequencies of 38 and 120 kHz, we estimated the density distribution of the moon jellyfish, Aurelia coerulea, in the Yeongsan Estuary, where a large bloom was detected. Aurelia aurita captured in nets had bell diameters of 3.2–22.0 cm and wet weights of 2.0–265.0 g, and the relationship between wet weight (W) and bell diameter ...

Blooms of the moon jellyfish, Aurelia coerulea, often occur in eutrophic embayments where microzooplankton are abundant. Hence, microzooplankton may play a role in A. coerulea population dynamics. In this study, feeding and growth responses of the ephyra and metephyra stages of A.

Mass occurrences of moon jellyfish have been observed in coastal waters. Strobilation directly determines the initial population size of adult jellyfish, but energy distribution during the strobilation process is not well understood. In this study, strobilation was induced in polyp of Aurelia coerulea by elevating temperature.

Hydrobiologia, 2018 In coastal areas with a high intensity of human activities, expansion of artificial structures may enhance Aurelia spp. blooms because these constructions may provide additional substrates for the settlement and proliferation of the polyps.

Ectodermal origin and tissue dedifferentiation in the podocyst production by the polyps of the Asian moon jelly ( Aurelia coerulea ) [PDF]
Journal of MorphologyAbstract The histological origin of podocysts in scyphozoans has long been undetermined, with uncertainty whether they arise from mesenchymal amoebocytes or stalk and pedal disc ectoderm in polyps. Histological investigation on the pedal disc was difficult due to the settlement of polyps on hard substrates.

Jellyfish blooms have become a hot research topic in recent decades because they pose a serious threat to fisheries, coastal industries, tourism, and the marine ecosystem. The life cycle of scyphozoan jellyfish consists of a pelagic medusa stage and a benthic polyp stage, where asexual reproduction and strobilation of the polyps directly affect the ...
