The impact of iron and chelators on Lake Kinneret phytoplankton

Utsa Pollingher, Bina Kaplan and Tom Berman

The israel Oceanographic & Limnological Research, Yigal Allon Kinneret Limnological Laboratory PO Box 345, Tiberias, Israel 14102

Received on August 21, 1994; accepted on June 28, 1995 The response of natural phytoplankton populations from Lake Kinneret to the addition of iron (Fe) and chelator (EDTA) was tested by following growth patterns and determining the algal composition initially and at the end of the experiments; algal growth rates and yield were measured by in vivo chlorophyll fluorescence. Although the pattern of growth response varied, usually some stimulation of phytoplankton growth rate and yield was observed with chelator and/or Fe addition in comparison to unsupplemented samples. However, the major impact of Fe and EDTA on the phytoplankton appeared to be expressed as changes in the algal population composition. There were clear taxonomic differences in the response to Fe addition, which in nearly all experiments stimulated outgrowth of Bacillanophyta and Chlorophyta, compared with the effect of EDTA alone or with Fe which enhanced the development of Cyanophyta, in addition to Bacillariophyta. The availability of Fe and/or chelators therefore appears to be important in determining the composition of the phytoplankton populations in Lake Kinneret and presumably in other aquatic environments.
