Factors associated with membership of a community in a cluster of high T. infestans infestation in the Moreno Department, Santiago del Estero, Argentina.

1Variables: Den, density of rural houses (# per sq. km); Dist, distance from a community to the nearest T. infestans infested community (meters); LST, mean maximum land surface temperature (°C); NDVI, Normalized Difference Vegetation Index (no units); Elev, mean elevation of each community (meters above sea level); Deg, percentage of landscape within 2 km of a village that was degraded (see text for details); Def, percentage of landscape within 2 km of a community that was deforested (see text for details); Crops, percentage of landscape within 2 km of a village that was modified for soy production.Symbols: X (variable tested in model); — (variable not tested in model); − (negative association) + (positive association);**(P≤0,01);*(0,01P≤0,05); NS (not significant).Δi = AICi−AICmin.ωi = exp (−1/2 Δi)/Σ exp (−1/2 Δi).Σ ωi(j): sum of ωi values from every model in which variable i was present. Indicates the relative importance of each independent variable in predicting the data.2Lowest AIC = 60.8.
