Fig. 1: Interannual abundance of microbial cells throughout the water column of Lake Dziani Dzaha.

Number of pico-eukaryotic and prokaryotic cells per mL of lake water was determined by flow cytometry on prefiltered samples excluding Limnospira cells. Number of Limnospira cells was estimated on raw water subsamples by microscopy following Utermöhl method for phytoplankton counting. Abundance scale is logarithmic. Samples collected before the seismic events are colored in green, whereas samples corresponding to the seismic event are in yellow and post event samples in red/purple.
