<p>Co-Uni performance during settling improves at higher relative settling densities.</p>

Each point represents a biological replicate; the fitted line shows the result of a simple linear regression (R² = 0.6981, adjusted R² = 0.6813). B) Net change in Co-Uni and Snowflake strain abundance during settling, shown as ln(settled CFU / unsettled CFU).

Points represent individual replicates; lines show linear fits across relative settling densities for each phenotype (Co-Uni: R² = 0.9727, adjusted R² = 0.9705). Only Co-Uni shows a positive slope, indicating density-dependent improvement in settling performance.</p>
