For each species, top‐ranked models are shown for each of the three spatiotemporal scales of analysis. Top‐ranked models were those within 2ΔAIC of the highest weighted model. The column k is the number of parameters in the model, ΔAIC indicates the difference in AIC scores from the top model, and R 2 is a pseudo‐R 2 measure describing the proportion of variance explained by each model relative to the variance explained in the null model. The top models for coyote and lynx at the daily scale were not included in subsequent analyses due to large confidence intervals.
