Harmful invader ctenophore Mnemiopsis leidyi's expansions in the Eurasian Seas, its spatio-temporal population dynamics depending on environmental conditions in recipient habitats have been synthesized. M. leidyi found suitable temperature, salinity and productivity conditions in the temperate and subtropical environments of the semi-enclosed seas, in the coastal areas of open basins and in closed water bodies, where it created autonomous populations. M. leidyi changes its phenology depending on seasonal temperature regime in different environments. We assessed ranges of sea surface temperature, sea surface salinity and sea surface chlorophyll values, sufficient for M. leidyi general occurrence and reproduction based on comprehensive long-term datasets, contributed by co-authors. This assessment revealed that there are at least two eco-types (Southern and Northern) in the recipient seas of Eurasia with features specific for their donor areas. The range of thresholds for M. leidyi establishment, occurrence and life cycle in both eco-types depends on variability of environmental parameters in their native habitats.
有害入侵生物钟形虫 Mnemiopsis leidyi 在欧亚海域的扩张及其时空种群动态取决于受体生境的环境条件，这已得到综合研究。Mnemiopsis leidyi 在半封闭海域的温带和亚热带环境、开阔盆地的沿海地区和封闭水体中找到了适宜的温度、盐度和生产力条件，在这些地方形成了自主种群。Mnemiopsis leidyi 根据不同环境的季节性温度变化改变其物候。我们根据共同作者提供的综合长期数据集，评估了足以支持 Mnemiopsis leidyi 普遍存在和繁殖的海面温度、盐度和海表叶绿素值范围。这一评估表明，欧亚受纳海域中至少存在两种生态型（南方型和北方型），具有其来源地区特有的特征。两种生态型中 Mnemiopsis leidyi 建立、出现和生命周期的阈值范围取决于其原生栖息地环境参数的可变性。
