Resilience Of A Deer Hunting System In Southeast Alaska: Integrating Social, Ecological, And Genetic Dimensions
Dissertation (Ph.D.) University of Alaska Fairbanks, 2009 I examined the interactions of key components of a hunting system of Sitka black-tailed deer (Odocoileus hemionus sitkensis) on Prince of Wales Island, Alaska to address concerns of subsistence hunters and to provide a new tool to more effect...
