Geologic studies in Alaska by the U.S. Geological Survey, 1997 Geologic studies in Alaska by the U.S. Geological Survey, 1997
The eight papers that follow continue the series of U.S. Geological Survey (USGS) reports on investigations in the geologic sciences in Alaska. The series presents new and sometimes preliminary findings that are of interest to earth scientists in academia, government, and industry; to land and resource managers; and to the general public. Reports presented in Geologic Studies in Alaska...

Cytochrome P450 1A induction in sea ducks inhabiting nearshore areas of Prince William Sound, Alaska Cytochrome P450 1A induction in sea ducks inhabiting nearshore areas of Prince William Sound, Alaska
Following the Exxon-Valdez oil spill, hepatic rates of EROD activity and thus, P450 1A expression, were significantly higher in harlequin ducks (Histrionicus histrionicus) and Barrow’s goldeneyes (Bucephala islandica) from oiled areas of Prince William Sound, Alaska when compared to birds from unoiled sites. Polychlorinated biphenyl exposure did not account for areal differences in P450...

Ecological correlates of mate fidelity in two Arctic-breeding sandpipers Ecological correlates of mate fidelity in two Arctic-breeding sandpipers
Monogamous birds exhibit considerable interspecific variation in rates of mate fidelity between years, but the reasons for this variation are still poorly understood. In a 4-year study carried out in western Alaska, mate-fidelity rates in Semipalmated Sandpipers (Calidris pusilla; mate fidelity was 47% among pairs where at least one mate returned and 94% among pairs where both mates...

Molecular genetic status of Aleutian Canada Geese from Buldir and the Semidi Islands, Alaska Molecular genetic status of Aleutian Canada Geese from Buldir and the Semidi Islands, Alaska
We conducted genetic analyses of Aleutian Canada Geese (Branta canadensis leucopareia) from Buldir Island in the western Aleutians and the Semidi Islands in the eastern portion of their breeding range. We compared data from seven microsatellite DNA loci and 143 base pairs of the control region of mitochondrial DNA from the two populations of Aleutian Canada Geese and another small-bodied

Densities of Barrow's goldeneyes during winter in Prince William Sound, Alaska in relation to habitat, food, and history of oil contamination Densities of Barrow's goldeneyes during winter in Prince William Sound, Alaska in relation to habitat, food, and history of oil contamination
We evaluated variation in densities of Barrow's Goldeneyes (Bucephala islandica) during winter at 214 sites within oiled and unoiled study areas in Prince William Sound, Alaska in relation to physical habitat attributes, prey biomass, and history of habitat contamination by the 1989 Exxon Valdez oil spill. Using general linear model analyses, we found that goldeneye densities were...

Distribution of recoveries of Steller's Eiders banded on the lower Alaska Peninsula, Alaska Distribution of recoveries of Steller's Eiders banded on the lower Alaska Peninsula, Alaska
Molting adult Steller's Eiders (Polysticta stelleri) were banded at Izembek Lagoon (1961-1998) and Nelson Lagoon (1995-1997) along the lower Alaska Peninsula to determine breeding distribution and movements. Of 52,985 Steller's Eiders banded, 347 were recovered. The overall low recovery rate may not be indicative of harvest levels but may be due to low reporting rates of bands. Almost...

Effects of neck collars and radiotransmitters on survival and reproduction of emperor geese Effects of neck collars and radiotransmitters on survival and reproduction of emperor geese
Neck collars have been used widely for studies of goose population biology. Despite concerns about their negative impacts, few studies have employed designs capable of clearly demonstrating these effects. During a 1993-98 study of emperor geese (Chen canagica), we contrasted survival and reproduction of geese marked with tarsal bands to those marked with either small neck collars, large...
