在咸海历史上，海平面和化学成分的波动在塑造咸海动植物群落方面发挥了重要作用。1960年，已知的11种介形类(甲壳纲)生活在咸海，由于过去30年人类活动导致的盐度上升，今天只有一种幸存下来。讨论了淡水和微咸水混合的介形类动物群的起源，并得出结论：一些主要的动物群元素一定是在与里海存在联系的过去高水位阶段到达咸海盆地的。阐明了关键类群的分类地位，并从全新世序列中阐明了1960年前咸海介形类动物群的主要成分：咸海、介形类、全新世、古湖相。
Fluctuations in the level and chemistry during its history have played a major part in shaping the floral and faunal communities of the Aral Sea. Of the eleven species of Ostracoda (Crustacea) known to have been living in the Aral Sea in 1960, only one survives today due to the anthropogenically induced salinity increase of the past three decades. The origins of a mixed fresh- and brackish-water ostracod fauna are discussed, and it is concluded that some of the major faunal elements must have reached the Aral Sea Basin during a past high water level phase when connection existed with the Caspian Sea. The taxonomic position of key taxa is clarified, and the major elements of the pre-1960 Aral Sea ostracod fauna are illustrated from Holocene sequences.Aral Sea, Ostracoda, Holocene, palaeolimnology.
