Abstract

The tolerances of many ostracode species to particular hydrochemical parameters are known based upon studies of living taxa from eastern and southern Africa range assemblages. A hydrochemical analysis of ostracodes applied to fossils from a radiocarbon-dated core from Lake Elmenteita, suggests that about 12 000 years BP, Elmenteita was a small, closed lake of Range IV salinity and alkalinity. It underwent a period of decreasing salinity and alkalinity, passing through Range III to a Range II, high-water phase, about 10 000 years BP. The lake remained in Range II prior to its rapid return to a Range IV, highly alkaline and saline, small-lake condition about 8000 years BP. These results demonstrate the great potential for recognizing regional paleohydrologic and paleoclimatic trends from tropical lacustrine ostracodes derived from cores. -from Authors
