Identification of linear and threshold responses in streams along a gradient of urbanization in Anchorage, Alaska Identification of linear and threshold responses in streams along a gradient of urbanization in Anchorage, Alaska
We examined biotic and physiochemical responses in urbanized Anchorage, Alaska, to the percent of impervious area within stream basins, as determined by high-resolution IKONOS satellite imagery and aerial photography. Eighteen of the 86 variables examined, including riparian and instream habitat, macroinvertebrate communities, and water/sediment chemistry, were significantly correlated...

Body molt of male long-tailed ducks in the nearshore waters of the north slope, Alaska Body molt of male long-tailed ducks in the nearshore waters of the north slope, Alaska
We examined the timing and intensity of body molt in relation to stage of remige growth for postbreeding adult male Long-tailed Ducks (Clangula hyemalis) off the coast of northern Alaska. During this period, remige and rectrix feathers are molted simultaneously with body feathers during the prebasic molt, which results in a period of increased energetic and nutritional demands. We...

Post-breeding distribution of Long-tailed Ducks Clangula hyemalis from the Yukon-Kuskokwim Delta, Alaska Post-breeding distribution of Long-tailed Ducks Clangula hyemalis from the Yukon-Kuskokwim Delta, Alaska
Breeding populations of Long-tailed Ducks Clangula hyemalis have declined in western Alaska, particularly on the Yukon-Kuskokwim (Y-K) Delta, and the species is currently considered a species of particular concern by the U.S. Fish & Wildlife Service in Alaska. Potential factors that may have contributed to this decline that occurred away from the breeding grounds could not be considered...

Monitoring in the nearshore: A process for making reasoned decisions Monitoring in the nearshore: A process for making reasoned decisions
Over the past several years, a conceptual framework for the GEM nearshore monitoring program has been developed through a series of workshops. However, details of the proposed monitoring program, e.g. what to sample, where to sample, when to sample and at how many sites, have yet to be determined. In FY 03 we were funded under Project 03687 to outline a process whereby specific...

Water resources data, Alaska, water year 2002 Water resources data, Alaska, water year 2002
Water resources data for the 2002 water year for Alaska consist of records of stage, discharge, and water quality of streams; stages of lakes; and water levels and water quality of ground water. This volume contains records for water discharge at 109 gaging stations; stage or contents only at 5 gaging stations; water quality at 26 gaging stations; and water levels for 45 observation...

Correlates to survival of juvenile sea otters in Prince William Sound, Alaska, 1992-1993 Correlates to survival of juvenile sea otters in Prince William Sound, Alaska, 1992-1993
We estimated survival of sea otters (Enhydra lutris) for 1 year post weaning during 1992-1993 in Prince William Sound (PWS), location of the 1989 Exxon Valdez oil spill. We sampled 38 pups in eastern PWS (EPWS), an unoiled area occupied by sea otters for

Harlequin duck (Histrionicus histrionicus) perspective: Harlequin duck population recovery following the Exxon Valdez oil spill: Progress, process, and constraints Harlequin duck (Histrionicus histrionicus) perspective: Harlequin duck population recovery following the Exxon Valdez oil spill: Progress, process, and constraints
Following the 1989 Exxon Valdez oil spill in Prince William Sound, Alaska, we studied the status of recovery of harlequin duck (Histrionicus histrionicus) populations during 1995-1998. We evaluated potential constraints to full recovery, including (1) exposure to residual oil, (2) food limitation, and (3) intrinsic demographic limitations on population growth rates. In this paper, we...
