Table 1 Generalized linear mixed model results for prairie crayfish burrow presence and density in a tallgrass prairie in Missouri. The null model, global model, and top models that were averaged to produce the final models are presented with difference in AIC (ΔAIC), Akaike weight (Wi), and log likelihood (LL). All models included a nested random effect for quadrat within burned quarter of the conservation area
