棘虫是一种世界性的物种，在世界各地的沿海和陆架海洋环境中都有报道。在过去100年左右的时间里，人们对它进行了广泛的研究，对文献的研究揭示了三个显著的特征：(1)在广泛的环境条件下存在种群；(2)大、小空间尺度上种群间丰度和生活史格局差异较大；(3)种群动态各方面的年际变化。aurita显然是一种高度灵活的物种，可以适应各种环境条件。虽然各种生理和行为特征解释了aurita种群如何利用周围环境，但它们并不能解释是什么支配了所观察到的丰度的时空模式，以及种群的寿命或寿命。了解这些特征对于预测水华种群如何形成是必要的。在一个特定的生境中，底栖海洋无脊椎动物的分布和丰度是由四个因素维持的：幼虫招募（有性繁殖）、迁徙、死亡和无性繁殖。本文的目的是为了确定底栖和远洋阶段的aurita在水母科种群中的繁殖和生活史策略，并特别关注aurita与周围物理和生物环境之间的动态相互作用。
The scyphozoan Aurelia aurita (Linnaeus) is a cosmopolitan species, having been reported from a variety of coastal and shelf sea environments around the world. It has been extensively studied over the last 100 years or so, and examination of the literature reveals three striking features: (1) the presence of populations in a wide range of environmental conditions; (2) large inter-population differences in abundance and life history patterns over large and small spatial scales; and (3) inter-annual variability in various aspects of its population dynamics. A. aurita is clearly a highly flexible species that can adapt to a wide range of environmental conditions. While various physiological and behavioural characteristics explain how A. aurita populations can take advantage of their surrounding environment, they do not explain what governs the observed temporal and spatial patterns of abundance, and the longevity or lifespan of populations. Understanding these features is necessary to predict how bloom populations might form. In a given habitat, the distribution and abundance of benthic marine invertebrates have been found to be maintained by four factors: larval recruitment (sexual reproduction), migration, mortality and asexual reproduction. The aims of this review are to determine the role of reproduction and life history strategies of the benthic and pelagic phases of A. aurita in governing populations of medusae, with special attention given to the dynamic interaction between A. aurita and its surrounding physical and biological environment.
