Universality dynamics of ARGs in terrestrial livestock. (a–d) Scatter plots and local trend lines for associations between resistome overlap (x) and dissimilarity (y) in farm sample pairs, stratified by same (a, c) and differing (b, d) countries (columns) and same (a, b) and differing (c, d) livestock species status (rows). (e) Model coefficients for $\mathit{log}\left(dissimilarity\right)~\mathit{log}\left(1-overlap\right)*Category$ where category encodes whether covariates are shared. On the x-axis, shifting further to the right suggests a more universal or stronger effect on the negativity of the dissimilarity–overlap curve.
