Combined Effects of Temperature and Salinity on Polyps and Ephyrae of <i>Aurelia solida</i> (Cnidaria: Scyphozoa)

Jellyfish outbreaks are conspicuous natural events in marine ecosystems that have a substantial impact on the structure and dynamics of marine ecosystems and different economic sectors of human activities. Understanding the life cycle strategies of jellyfish species is therefore critical to mitigate...
