Phytochemistry predicts habitat selection by an avian herbivore at multiple spatial scales.

abstract：:Statistical thinking in wildlife biology and ecology has been profoundly influenced by the introduction of AIC (Akaike's information criterion) as a tool for model selection and as a basis for model averaging. In this paper, we advocate the Bayesian paradigm as a broader framework for multimodel inference, one in whic...
