Comparing the effects of resource enrichment and grazing on a bacterioplankton community of a meso-eutrophic reservoir.

Original language description

We examined changes in a microbial community in reaction to shifts in predation pressure and resources in a meso-eutrophic reservoir. Manipulations consisted of size fractionation and either in situ incubation or transplantation from the dam area to theriver area, which differed in P-availability. We monitored bacterial abundance, bacterial production, protistan grazing, as well as bacterial community composition (BCC). Populations transplanted to the relatively P-rich river area showed a 3- to 6-foldincreases in bacterial and heterotrophic nanoflagellates abundance and bacterivory compared to the treatments incubated at the dam area. In the transplanted community, nearly all groups of bacteria showed increased growth rates. In contrast, at the moreP-limited dam, the top-down manipulations induced significant changes in BCC. Thus, we found that BCC changes with predation in resource-limited bacterioplankton but that predation plays a minor role when resource limitation is relaxed.
