Fig. 4

Heatmaps of α-diversity across a range of subpopulation sizes and host dispersal rate under different combinations of MA _x and ME _y. Each heatmap corresponds to a combination of MA _x and ME _y both of which has three levels (10%, 50%, and 90%). For each heatmap, horizontal and vertical axes represent the host dispersal rate and number of host subpopulations, respectively. The scales are logarithmic with range from 1 to 4096 for vertical axes and range from 1 to e⁻¹⁰ for horizontal axes. The color on the right of the heatmaps indicates the corresponding values for diversity (warm color: high diversity; cold color: low diversity)
