We conducted seabird surveys along the entire coast of the Chukotka Peninsula (northwestern Siberia, Russia) from 1983 to 1991. We present the first comprehensive descriptions of the distribution and size of Chukotkan seabird colonies. Thirteen species of seabirds were recorded breeding on the peninsula, with an additional 13 migrant or...
Estimating survival rates with age-structure data
Mark S. Udevitz, Brenda E. Ballachey
1998, Journal of Wildlife Management (62) 779-792
We developed a general statistical model that provides a comprehensive framework for inference about survival rates based on standing age-structure and ages-at-death data. Previously available estimators are maximum likelihood under the general model, but they use only 1 type of data and require the assumption of a stable age structure...
Caribou distribution during the post-calving period in relation to infrastructure in the Prudhoe Bay oil field, Alaska
Matthew A. Cronin, Steven C. Amstrup, George M. Durner, Lynn E. Noel, Trent L. McDonald, Warren B. Ballard
1998, Arctic (51) 85-93
There is concern that caribou (Rangifer tarandus) may avoid roads and facilities (i.e., infrastructure) in the Prudhoe Bay oil field (PBOF) in northern Alaska, and that this avoidance can have negative effects on the animals. We quantified the relationship between caribou distribution and PBOF infrastructure during the post-calving period (mid-June...
Hermit crabs in the diet of Pigeon Guillemots at Kachemak Bay, Alaska
Michael A. Litzow, John F. Piatt, Jared D. Figurski
1998, Colonial Waterbirds (21) 242-244
Guillemots (Cepphus spp.) feed their chicks a diet that is almost exclusively fish. We observed Pigeon Guillemots (C. columba) at two colonies in Alaska where hermit crabs (Crustacea: Anomura) were a major part of the diet for some nestlings. Hermit crabs were delivered to three of five observed nests at...
Synthetic aperture radar interferometry coherence analysis over Katmai volcano group, Alaska
Z. Lu, J.T. Freymueller
1998, Journal of Geophysical Research B: Solid Earth (103) 29887-29894
The feasibility of measuring volcanic deformation or monitoring deformation of active volcanoes using space-borne synthetic aperture radar (SAR) interferometry depends on the ability to maintain phase coherence over appropriate time intervals. Using ERS 1 C band (λ=5.66 cm) SAR imagery, we studied the seasonal and temporal changes of the interferometric...

S. M. Hodge, D.C. Trabant, R. M. Krimmel, T.A. Heinrichs, R.S. March, E.G. Josberger
1998, Journal of Climate (11) 2161-2179
Time series of net and seasonal mass balances for three glaciers in western North America, one in the Pacific Northwest and two in Alaska, show various relationships to Pacific hemisphere climate indexes. During the winter season the two coastal, maritime-regime glaciers, over 2000 km apart, are affected almost identically, albeit...
Structural and kinematic evolution of the Yukon-Tanana upland tectonites, east-central Alaska: A record of late Paleozoic to Mesozoic crustal assembly
V. L. Hansen, Cynthia Dusel-Bacon
1998, Geological Society of America Bulletin (110) 211-230
The Yukon-Tanana terrane, the largest tectonostratigraphic terrane in the northern North American Cordillera, is polygenetic and not a single terrane. Lineated and foliated (L-S) tectonites, which characterize the Yukon-Tanana terrane, record multiple deformations and formed at different times. We document the polyphase history recorded by L-S tectonites within the Yukon-Tanana...

Paul L. Flint, A. C. Fowler
1998, Marine Pollution Bulletin (36) 165-166
We used wooden blocks to estimate the proportion of oiled seabird carcasses that were likely to be recovered on beaches of St Paul Island, Alaska following a near-shore oil spill. We released a total of 302 blocks 6 km north of the island in 1997 at the site of a...
Effect of lead poisoning on spectacled eider survival rates
J. Barry Grand, Paul L. Flint, Margaret R. Petersen, Christine L. Moran
1998, Journal of Wildlife Management (62) 1103-1109
Spectacled eider (Somateria fischeri) populations on the Yukon-Kuskokwim Delta (Y-K Delta), Alaska, declined rapidly through the 1980s, and low adult female survival was suggested as the likely cause of the decline. We used mark-resighting techniques to study annual survival rates of adult female spectacled eiders at 2 sites on the...

S.B. Kuznetsov, Vasily V. Baranyuk, John Y. Takekawa
1998, The Auk (115) 1053-1057
Arctic breeding populations of Lesser Snow Geese (Chen c. caerulescens) range from Baffin Island in eastern Canada to Wrangel Island, Russia, which is located 650 km west of Alaska (Bellrose 1980). Although hundreds of thousands of Lesser Snow Geese may have occupied the Russian arctic in the mid1800s (see Takekawa...
Certainty of paternity and paternal investment in eastern bluebirds and tree swallows
Bart Kempenaers, Richard B. Lanctot, Raleigh J. Robertson
1998, Animal Behaviour (55) 845-860
Extra-pair paternity is common in many socially monogamous passerine birds with biparental care. Thus, males often invest in offspring to which they are not related. Models of optimal parental investment predict that, under certain assumptions, males should lower their investment in response to reduced certainty of paternity. We attempted to...
Effect of implanted satellite transmitters on the nesting behavior of Murres
P.M. Meyers, Scott A. Hatch, D.M. Mulcahy
1998, Condor (100) 172-174
We implanted 6 Common Murres (Uria aalge) and 10 Thick-billed Murres (Uria lomvia) with satellite transmitters and compared subsequent presence at the colony, nesting status, and provisioning to a control group that underwent a simple surgical procedure. In the 10 days following implantation, we resighted 10 of 11 control birds...
Attraction of brown bears to red pepper spray deterrent: Caveats for use
Tom S. Smith
1998, Wildlife Society Bulletin (26) 92-94
Humans in brown bear (Ursus arctos) country may unexpectedly encounter hears with sometimes harmful consequences. Firearms may be an effective defense, but they destroy bears, their use is illegal in most national parks, and many people prefer not to carry them, Consequently, nonlethal bear deterrents have long been sought as...
Ecological, morphological, genetic and life history characteristics of two sockeye salmon populations, Tustumena Lake, Alaska
Carol Ann Woody
1998, Thesis
Populations can differ in both phenotypic and molecular genetic traits. Phenotypic differences likely result from differential selection pressures in the environment, whereas differences in neutral molecular markers result from genetic drift associated with some degree of reproductive isolation. Two sockeye salmon, Oncorhynchus nerka, populations were compared using both phenotypic and...
