Reproduction, preweaning survival, and survival of adult sea otters at Kodiak Island, Alaska
Daniel H. Monson, Anthony R. DeGange
1995, Canadian Journal of Zoology (73) 1161-1169
Radiotelemetry methods were used to examine the demographic characteristics of sea otters inhabiting the leading edge of an expanding population on Kodiak Island, Alaska. Fifteen male and 30 female sea otters were instrumented and followed from 1986 to 1990. Twenty-one percent of females were sexually mature (had pupped) at age...
Viral hemorrhagic septicemia virus in North America
Theodore R. Meyers, James R. Winton
1995, Annual Review of Fish Diseases (5) 3-24
The first detections of viral hemorrhagic septicemia virus (VHSV) in North America were in Washington State from adult coho (Oncorhynchus kisutch) and chinook (O. tshawytscha) salmon in 1988. Subsequently, VHSV was isolated from adult coho salmon returning to hatcheries in the Pacific Northwest in 1989, 1991 and 1994. These isolates...
Movements of a polar bear from northern Alaska to northern Greenland
George M. Durner, Steven C. Amstrup
1995, Arctic (48) 338-341
Using satellite telemetry, we monitored the movements of an adult female polar bear (Ursus maritimus) as she traveled from the Alaskan Beaufort Sea coast to northern Greenland. She is the first polar bear known to depart the Beaufort Sea region for an extended period, and the first polar bear known...
Correlation of Ordovician rocks of northern Alaska

1995, Conference Paper, Ordovician odyssey: Short papers for the seventh international symposium on the Ordovician system (SEPM Book 77)
The Ordovician sequences presented in this report were chosen to cover a range of depositional and structural settings found in northern Alaska. Consequently, the quality of lithostratigraphic, paleontologic, and sedimentologic data is variable. Until 1982, Ordovician rocks in northern Alaska were known only from a few, widely separated localities. Since...
Brood amalgamation in the Bristle-thighed Curlew Numenius tahitiensis: process and function
Richard B. Lanctot, Robert E. Gill Jr., T. Lee Tibbitts, Colleen M. Handel
1995, Ibis (137) 559-569
Alloparental care in birds generally involves nonbreeding adults that help at nests or breeding adults that help raise young in communal nests. A less often reported form involves the amalgamation of broods, where one or more adults care for young that are not their own. We observed this phenomenon among...
Water over the bridge
John F. Piatt
1995, American Scientist (83) 396-398
The March-April issue of American Scientist contains a commentary by Julia K. Parrish and P. Dee Boersma (Macroscope, "Muddy Waters") that purports to "assess the validity of the claims made concerning seabird mortality as a result of the [Exxon Valdez oil] spill." Parrish and Boersma would have us believe that...
Release strategies for rehabilitated sea otters

1995, Book chapter, Emergency care and rehabilitation of oiled sea otters: A guide for oil spils involving fur-bearing marine mammals
According to the U.S. Fish and Wildlife Services’ (USFWS) Response Plan for sea otters (USFWS, in preparation), in the event of an oil spill, the decision to release sea otters from rehabilitation centers following treatment will be linked to the decision on whether to capture sea otters for treatment. Assuming...
Deposition and persistence of beachcast seabird carcasses
Thomas I. van Pelt, John F. Piatt
1995, Marine Pollution Bulletin (30) 794-802
Following a massive wreck of guillemots (Uria aalge) in late winter and spring of 1993, we monitored the deposition and subsequent disappearance of 398 beachcast guillemot carcasses on two beaches in Resurrection Bay, Alaska, during a 100 day period. Deposition of carcasses declined logarithmically with time after the original event....
Increasing frequency of plastic particles ingested by seabirds in the subarctic North Pacific
Martin D. Robards, John F. Piatt, Kenton D. Wohl
1995, Marine Pollution Bulletin (30) 151-157
We examined gut contents of 1799 seabirds comprising 24 species collected in 1988-1990 to assess the types and quantities of plastic particles ingested by seabirds in the subarctic waters of Alaska. Of the 15 species found to ingest plastic, most were surface-feeders (shearwaters, petrels, gulls) or plankton-feeding divers (auklets, puffins)....
Census methodologies of Black-legged Kittiwakes in Glacier Bay National Park

1995, Conference Paper, Proceedings of the third Glacier Bay science symposium
Black-legged Kittiwakes (Rissa tridactyla) have recently experienced widespread population declines and frequent colony failures throughout the North Pacific. At Glacier Bay National Park, the Margerie Glacier colony was censused visually in 1991 through 1993. In 1993 a new photographic census technique was also tested to assess its feasibility, accuracy, and...

Brown bears (Ursus arctos middendorffi) on the Kodiak Archipelago are famous for their large size and seasonal concentrations at salmon streams. Sport hunting of Kodiak bears has been popular since World War II. Their value as captivating subjects to observe or photograph is a more recent development that is increasing...
Prey preference of Pacific halibut (Hippoglossus stenolepis) in Glacier Bay National Park

1995, Conference Paper, Proceedings of the third Glacier Bay science symposium
Stomach contents were collected from sport-caught halibut in Glacier Bay National Park. Stomach samples containing a combination of fish and invertebrate species were observed less frequently than expected. Small, subtidal, noncommercial crab and cod-like fish (Gadidae) appear to be the most important prey items. In thc dict of Pacific halibut....

We investigated patterns of winter wolf predation, including prey selection, prey switching, kill rates, carcass utilization, and consumption rates for four wolf packs during three different study periods (March 1989, March 1990, and November 1990) in Gates of the Arctic National Park and Preserve, Alaska. Wolves killed predominantly caribou (165...

1995, Open-File Report 95-669
We are engaged in a five-year study to test the hypothesis that methane from decomposing gas hydrates may contribute methane to the atmosphere. The release of methane, a "greenhouse" gas, can enhance global warming and be a factor in global climate change. As part of the study we have measured the...

1994, Northwestern Naturalist (75) 81-87
The number of spectacled eiders nesting on two study areas near the Kashunuk River, on the central Yukon-Kuskokwim (Y-K) Delta, Alaska, declined by over 75% in the last 20 years. Nesting densities have remained low, but have not significantly declined since 1985. There has been no decrease in the reproductive...

Early naturalists exploring western Alaska were intrigued to find a stocky, blue-gray species of coastal goose unique to that area and nearby Russia. As E. W. Nelson (1887) wrote, "Among the various species of birds more or less peculiar to Alaska this goose is perhaps the most noteworthy." The Emperor...
Functional response of wolves preying on barren-ground caribou in a multiple-prey ecosystem
B.W. Dale, Layne G. Adams, R.T. Bowyer
1994, Journal of Animal Ecology (63) 644-652
1. We investigated the functional response of wolves (Canis lupus) to varying abundance of ungulate prey to test the hypothesis that switching from alternate prey to preferred prey results in regulation of a caribou (Rangifer tarandus) population at low densities. 2. We determined prey selection, kill rates, and prey abundance...
Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals
A. Keith Miles, Susan Hills
1994, Marine Pollution Bulletin (28) 456-458
Elevated levels of cadmium in Pacific walrus (Odobenus rosmarus divergens) and northern fur seals (Callorhinus ursinus) have been reported in populations from the Bering Sea (Goldblatt & Anthony, 1983; Taylor et al., 1989). Russian and US authorities are concerned because of the possible health hazards from consuming pinniped meat harvested...
