Table 2 Multivariate linear model coefficients assessing overlap of gray wolves (Canis lupus) with prey on and near the Grand Portage Indian Reservation, Minnesota, USA, 2012–2021. Comparisons of logit-transformed proportional overlap of individual-level wolf 95% UDs with population-level 95% occurrence distributions of moose (Alces alces), the white-tailed deer (Odocoileus virginianus) migration corridor, the composite deer population, migratory deer only, or resident deer only are presented

From: Spatial overlap of gray wolves and ungulate prey changes seasonally corresponding to prey migration
