Model selection results for the best approximating model of DSR of nests for female greater sage-grouse in the Wind River Basin in central Wyoming, USA. Model selection was based on ΔAICc using the landscape model (see Table 2) as the null model from which to base model fit with the addition of weather variables. Only models ≤ 2 ΔAICc units from the null landscape model are reported, unless AICc was lower than the null landscape model. K, number of parameters in model; AICc, Akaike's information criterion corrected for small sample size; w_i, Akaike weights; max, maximum.
