Method Note: 5-ml preserved samples were analyzed using a modified version of
             the flow cytometer in which each optical signal was split and
             measured by two photomultipliers at different gain settings, which
             increased the dynamic range of the measurements (allowing cells
             ranging in size from 1 to 40 micrometers to be analyzed
             simultaneously).
