Demographic patterns of chronic wasting disease infection
My research examines the role that social organization of female white-tail deer plays in the probability of CWD infection in Wisconsin. Female white-tailed deer live in a rigid social structure based on family relationships. I believe that this rigid social structure and high density of white-tailed deer in southern Wisconsin will provide a way to better characterize how CWD spreads between female deer in the same social group and between different groups.
