| Abstract |
We studied the effects of predation on the cytometric and phylogenetic features of two enriched bacterial communities obtained from two cultures of marine heterotrophic nanoflagellates: Jakoba libera and a mixed culture of Cafeteria sp. and Monosiga sp. Protists were harvested by flow cytometric cell sorting and eight different treatments were prepared. Each bacterial community was incubated with and without protists, and we added two treatments with protists and the bacteria present after the sorting procedure (cosorted bacteria). The bacterial community derived from the culture of Jakoba libera had higher green fluorescence per cell (FL1) than that derived from the mixed culture of Cafeteria sp. and Monosiga sp. When the experiment began all treatments presented bacterial communities that increase in fluorescence per bacterium (FL1); after that the FL1 decreased when bacteria attained maximal concentrations; and, finally, there was a new increase in FL1 toward the end of the experiment. Cosorted bacteria of Jakoba libera had the same fluorescence as the bacterial community derived from this protist, while the bacteria derived from the mixed culture of Cafeteria sp. and Monosiga sp. was nearly twice as fluorescent than that of the parental community. All treatments presented a general decline of SSC along the incubation. Therefore, there was a small influence of protists on the cytometric signature of each bacterial community. However, each bacterial community preyed by Jakoba libera or the mixed culture of Cafeteria sp. and Monosiga sp. led to four different phylogenetic fingerprint. Besides, the final Communities were different from the fingerprint of controls without protists, and most of them diverge from the fingerprint of cosorted bacteria. Our results confirm that changes in the phylogenetic composition of marine bacterial communities may depend on the initial communities of both bacteria and protists. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 July 2020.
All research outputs
#7,454,427
of 22,789,566 outputs
Outputs from Microbial Ecology
#788
of 2,058 outputs
Outputs of similar age
#20,209
of 56,856 outputs
Outputs of similar age from Microbial Ecology
#3
of 13 outputs
Altmetric has tracked 22,789,566 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,058 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one is in the 46th percentile – i.e., 46% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 56,856 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 13 others from the same source and published within six weeks on either side of this one. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
