"Bacterivorous protists are known to induce changes in bacterial community composition (BCC). We hypothesized that changes in BCC could be related quantitatively to a measure of grazing: the ratio of bacterial mortality to growth rate. To test this hypothesis, we analyzed changes in BCC, protistan grazing rate, and bacterial production from 3 in situ studies and 3 laboratory studies. Change in BCC, using different rRNA-targeted oligonucleotide probes, was estimated as the sum of changes in the proportions of the different phylogenetic groups of bacteria. Analysis of a set of 22 estimates of shifts in the ratio of grazing to production rate over periods of 48 -72 h and the corresponding changes in BCC showed that they were positively and tightly correlated (R squared = 0.784). While the nature of a shift in BCC is unpredictable, the magnitude of the change can be related to changes in the balance between bacterial production and protistan grazing."@en . . . "Dolan, J.
