||Primary source abstract: "[Investigators] analyzed changes in bacterioplankton morphology and composition during enhanced protozoan grazing by image analysis and fluorescent in situ hybridization with group-specific rRNA-targeted oligonucleotide probes. Enclosure experiments were conducted in a small, fishless freshwater pond which was dominated by the cladoceran Daphnia magna."
||P.685 right column 2nd paragraph: "Individual rod-shaped cells longer than 6 μm are too large for the filter-feeding zooplankton Daphnia magna, and grazing by this predator provokes accumulation of at least five different types of bacterial filaments: long rods, curved and S-shaped cells, threads, filaments with pointed ends, and cells in chains (primary source)."
