  1. Notes: Only significant interactions are shown in the equations; full equations can be found in Additional file 4: Table S6. Arrows indicate whether an effect of rodent density was positive, negative or none. Two arrows, one going up and one going down indicate non-linear association (parabola). Asterisks denote significance of an effect (*P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001)
