Method Extrapolation of P.n. ssp. asymbioticus abundance data obtained in a systematic but geographically limited survey of more than 100 standing freshwater systems estimated an average global contribution of 20% to bacterioplankton cells in freshwater systems [primary source], but pronounced inter-habitat differences in relative abundance of these bacteria were observed.
