Scale-Dependent Browsing Patterns on Canada Yew (Taxus canadensis) by White-Tailed Deer (Odocoileus virginianus)

Table 2

Model selection results from analysis of white-tailed deer browsing intensity on Canada yew in relation to local and site-level factors in northern/mixed hardwood forests in the Upper Peninsula, Michigan, 2001-2002. A post  hoc model selection analysis was conducted after results from the a  priori exercise suggested model fit could be improved.
