摘要
The authors studied a 475 cm long sediment core (QH-2005) retrieved from the southeastern part of Qinghai Lake. The authors speculate that lake water salinity was one of the most important factors influencing the L.inopinata body length,but not necessarily the only one factor. Other factors including water temperature,water depth and water chemical composition could as well exert certain influences on the micro-habitat of ostracoda and hereby in turn give rise to changes in ostracoda body length.
