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 25 years. We compared survival between areas, sexes, and condition groups. We also examined the relation of blood parameters to...

Incubation behaviour of Greater Scaup Aythya marila on the Yukon-Kuskokwim Delta, Alaska Incubation behaviour of Greater Scaup Aythya marila on the Yukon-Kuskokwim Delta, Alaska

This study examined the incubation behaviour of Greater Scaup Aythya marila on the Yukon-Kuskokwim Delta, Alaska. The goals of the study were to describe the incubation behaviour of Greater Scaup in terms of incubation constancy, recess frequency and recess length. The use of endogenous reserves by Greater Scaup was examined by determining weight loss over the incubation period. Further

Surgical implantation of transmitters into fish Surgical implantation of transmitters into fish

Although the Animal Welfare Act does not cover poikilotherms, individual institutions and policies and legal requirements other than the Animal Welfare Act (e.g., the US Public Health Service and the Interagency Research Animal Committee's Principles for the Utilization and Care of Vertebrate Animals Used in Testing, Research, and Training) require the review of projects involving fish...

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...

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...

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...

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...

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...

Pop-up archival transmitting (PAT) tags: A method to investigate the migration and behavior of Pacific halibut (Hippoglossus stenolepis) in the Gulf of Alaska Pop-up archival transmitting (PAT) tags: A method to investigate the migration and behavior of Pacific halibut (Hippoglossus stenolepis) in the Gulf of Alaska

Pop-up archival transmitting (PAT) tags provide a fisheries-independent method of collecting environmental preference data (depth and ambient water temperature) and migration distance. In this study, we evaluate the use of pop-up archival transmitting tags as a method to investigate demersal fish. We report the results from eight pop-up archival transmitting tagged Pacific halibut...
