Estimation of Abundance and Demographic Rates of Pacific Walruses in the Bering and Chukchi Seas, 2015
This study estimated abundance and demographic rates, including survival and recruitment, of Pacific walruses in the Beaufort Sea in 2015. The data collected was used to determine the feasibility of conducting a large scale and long-term capture-mark-recapture effort to determine the size of the Pac...
