奥雷利亚属是主要的开花水母种类之一。息肉期在其暴发中起重要作用。为了确定温度和食物条件如何影响繁殖过程，我们在实验室中将奥雷利亚属1种息肉置于三种温度（10-15°C）和四种食物浓度（0-0.1 mg C l−1）下，以测试它们对横裂过程以及芽和叶状体产生的综合影响。雄裂准备期的长度随温度的升高而显著降低，但不受食物条件的影响。有了足够的食物供应，已经释放出叶绿素的珊瑚虫重新开始了横裂过程。食物条件对芽和芽的产生都有积极影响。然而，温度有不同的影响：在测试的三个温度下，13°C最适合珊瑚虫释放Ephylaxis，而芽的产量在15°C时最高。这些结果表明，富营养化（作为食物条件的代理）会影响的大小的奥雷利亚sp. 1水螅人口和少年水母人口，而温度调节生殖能量分配之间的萌芽和ephyra释放调节的横裂过程。这种温度调节机制可能有助于使水母幼体的生产与浮游动物生物量的峰值相匹配。
Aurelia spp. are among the main blooming jellyfish species. The polyp stage plays an important role in its outbreaks. To determine how temperature and food conditions may affect the process of reproduction, we maintained Aurelia sp. 1 polyps in the laboratory at three temperatures (10–15°C) and four food concentrations (0–0.1 mg C l−1) to test their combined effects on the strobilation process and the production of buds and ephyrae. The length of the strobilation preparation period significantly decreased with increased temperature, but was not affected by food conditions. With sufficient food supply, the polyps that had already released ephyrae restart the strobilation process. Food condition positively affects both the production of buds and ephyrae. Temperature, however, had different effects: at the three temperatures tested, 13°C was most appropriate for polyps to release ephyrae, while bud production was highest at 15°C. These results suggest that eutrophication (as a proxy for food condition) would affect both the size of the Aurelia sp. 1 polyp population and juvenile medusa population, whereas temperature adjusts the reproductive energy distribution between budding and ephyra release to regulate the strobilation process. This temperature adjustment mechanism likely helps match the production of juvenile medusae with the peak of zooplankton biomass.
