Lines represent predicted population densities from a linear mixed-effects model fit to replicate data. Transfers were conducted every 24 hours under settling selection. The minimum detection threshold for both strains was approximately 12.5 ln(CFU/mL). Panel headers (0.25, 0.5, 0.75, 1) indicate relative settling density.</p> 2026-10-01T17:35:57Z Image Figure 10.1371/journal.pone.0359779.g001 https://figshare.com/articles/figure/_p_Low_settling_densities_reduce_Co-Uni_population_densities_over_time_p_/34048694 CC BY 4.0
