Predation assays resulting in initial observation of survivor P. putida. (A) Three day sequence of a C. ferrugineus-P. putida predation assay depicting complete swarming of spotted prey lawns with no visible parent P. putida biomass; red arrows indicate C. ferrugineus swarm edge. Day 0 panel is only P. putida biomass prior to introduction of C. ferrugineus. (B) Day 10 of C. ferrugineus-P. putida predation assay depicting incomplete swarming of prey lawns; red arrow indicates C. ferrugineus swarm edge. Comparison of colony sizes of (C) parent P. putida colonies and (D) survivor P. putida colonies depicting small colony variation. All scale bars depict 1 mm.
