DOI: 10.1007/s10811-017-1246-8
Abstract: Microcystis colonies can overwinter in sediment and may inoculate the water column through recruitment, promoting the annual recurrence of Microcystis blooms. Through microcosm experiments, the survivability of benthic Microcystis was quantitatively investigated by elucidating the… read more here.
