  1. Model-selection parameters from competing models used to explain the effects of local-habitat parameters on American pika (Ochotona princeps) occurrence in western Wyoming, USA, June – October, 2010 – 2012; K, number of parameters in the model; AICc, Akaike Information Criterion corrected for small samples; Δ AICc, difference for model relative to the smallest AICc in the model set; W j, Akaike weight is the approximate probability in favor of the given model from the set of models considered; E j represents the weight of evidence in support of a model, compared to the top ranked model (W jTop/W ji)
