We chose best approximating models estimating CWD prevalence in relation to differences in human land use, sex, and geograph...

We studied sexual segregation, particularly patterns of group membership for white-tailed deer (Odocoileus virginianus), in Lincoln County, Minnesota, USA, to evaluate current techniques used to categorize animals when studying sexual segregation. We categorized group membership according to Hirth (1977) and grouped individuals using our solitary categorization method. Our solitary method was m...
