Project Year and Number: 1995: 95025

Other Fiscal Years and Numbers for this Project: 1995: 95025-A

Principal Investigator (PI): Leslie Holland-Bartels (US Geological Survey)

Managing Agency: USGS

Assisting Personnel: Brenda Ballachey, Jim Bodkin, Terry Bowyer, Tom Dean, Lawrence Duffy, Dan Esler, Stephen Jewett, Karen Laing, Lyman McDonald, Chuck O'Clair, Alan Rebar, Dan Roby, Paul Snyder, Glenn Van Blaricom

Research Location: Prince William Sound

Restoration Category: Research

Injured Resources Addressed: Harlequin Ducks, Pigeon Guillemot, River Otters, Sea Otters

Abstract: The NVP study will include assessments of abundance, reproduction, mortality, prey selection, bioindicators, and individual health for sea otters, harlequin ducks, river otters and pigeon guillemots. Measures of population status will be integrated with the abundances and size class distributions of prey species that compose most of their diets. Demography will be examined by comparing population densities and parameters affecting population growth rates between oiled and unoiled sites. Exposure to oil will be assessed by comparing indicators of exposure to oil and individual health between oiled and unoiled sites. Food limitation will be considered by examining population densities and size class structures of dominant prey species.
