Fig. 3From: Relative abundance of Mycobacterium bovis molecular types in cattle: a simulation study of potential epidemiological driversComparison of observed relative abundance distributions (lines) and 95% envelopes for neutral predictions (shading) for observed distributions of molecular types for: NI M. bovis MVLA-types aggregated across the study period (a); NI M. bovis MVLA-types separated by year (b); NI M. bovis spoligotypes aggregated across the study period (c). Graphs show log-scaled absolute abundance of each molecular type on the y-axis, compared to the ranked abundance of each type on the x-axis (where the most common types have a rank of 1, and increasing ranks indicate less abundant types)Back to article page
