چکیده
This project investigated population status, habitat use and trophic interactions of harbor seals in Prince William Sound (PWS), Alaska. Aerial counts to monitor population trend indicated a 3.3% annual decline during 1990-1999. Counts were 20% lower in 1999 than in 1990, and >50% lower than in 1988. We sampled 390 seals during 1992-2000 and satellite-tagged 47 non-pups and 27 pups. Most tagged seals remained within PWS. Locations were almost all in water < 200 m deep. Subadults moved more, had larger home ranges, spent more time diving, dived more often, displayed a stronger diurnal
