    Techniques Used:

    Quantitative analysis using the bacterial cell envelope thickness tool. ( a ) Radial plots of Pantoea sp. YR343 envelope thickness in R2A, MOPS + glucose, and MOPS + succinate media. The 0° position marks pole 1, followed counterclockwise by side 1 (90°), pole 2 (180°), and side 2 (270°). ( b ) Violin plots showing global thickness distributions across media types. ( c ) Correlation between AI- and manual-based thickness measurements (n=50).

    A | Shannon diversity shown separately for each resource environment. The x- axis shows the total carbon level (doubling concentrations spaced evenly) and point color indicates resource complexity level. The figure contains 768 data points (8 replicates in 96 resources). B | Hump metric for total carbon gradient ( y -axis) at each level of resource complexity ( x -axis). Points show the estimated peak height (hump statistic); error bars show 95 % bootstrap confidence intervals. C | Variance partitioning of Shannon diversity using nested linear models. Bars show unique R 2 contributions of total carbon level, resource complexity (% R2A carbon contribution), and their interaction. Alt text. Three-panel figure representing diversity measures, with panel A containing data on Shannon diversity, resolved for each resource environment, panel showing a hump metric for total carbon gradient ( y -axis) at each level of resource complexity ( x -axis), and panel C showing variance partitioning of Shannon diversity using nested linear models.
