Timelines and mechanisms of wildlife population recovery following the Exxon Valdez oil spill

Exxon Valdez Oil Spill

Pristane (2,6,10,14-tetramethylpentadecane) concentrations in mussels (Mytilus trossulus) increase abruptly during spring in Prince William Sound (PWS), Alaska. This increase is mainly due to ingestion by mussels of pristane-laden feces produced by near-shore zooplanktivores, especially juvenile pink salmon (Oncorhynchus gorbuscha). Examination of the trophic and temporal distribution of prista...

Exxon Valdez Oil Spill

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...

Harlequin Duck population injury and recovery dynamics following the 1989 Exxon Valdez oil spill.

The 1989 Exxon Valdez oil spill caused significant injury to wildlife populations in Prince William Sound, Alaska, USA. Harlequin Ducks (Histrionicus histrionicus) were particularly vulnerable to the spill and have been studied extensively since, leading to one of the most thorough considerations of the consequences of a major oil spill ever undertaken. We compiled demographic and survey data c...

M arbled murrelets, Brachyramphus marmoratus marmoratus, are small seabirds of the Alcid Family. Alcids are diving seabirds inhabiting the north Pacific and include murres, puffins, auklets, murrelets, and guillemots. Marbled murrelets occur in nearshore marine environments from California to Alaska, nesting primarily in old-growth forests. A larger subspecies, B. m. perdix, is found along the ...
