Scott A. Hatch
Kees Vermeer, K.T. Briggs, K.H. Morgan, D. Siegel-Causey, editor(s)
1993, Conference Paper, The status, ecology and conservation of marine birds of the North Pacific
In the North Pacific, the breeding distribution of Northern Fulmars (Fulmarus glacialis) includes about equal numbers of very large colonies (50,000-500,000 individuals) and relatively small ones (5-5,000 individuals). The almost complete segregation of light and dark colour phases between adjacent colonies in the Bering Sea and Sea of Okhotsk suggests...

1993, Veterinary Pathology (30) 1-11
Following the Exxon Valdez oil spill in Prince William Sound, Alaska, sea otters (Enhydra lutris) that appeared to be contaminated with oil, that were in danger of becoming contaminated, or that were behaving abnormally were captured and taken to rehabilitation centers. Exposure to oil was assessed by visual examination when...
Are Bald Eagles important predators of Emperor Geese?
Robert E. Gill Jr., Karen L. Kincheloe
1993, Journal of Raptor Research (27) 34-36
Bald Eagles (Haliaeetus leucocephalus) and geese often occur together, especially at sites used by geese for migrational staging and wintering. Although numerous studies have been directed at these taxa, there are only anecdotal accounts (Parris et al. 1980, Bennett and Klaas 1986, Bartley 1988) of Bald Eagles killing healthy geese...

Population trends of Alaskan seabirds
Scott A. Hatch
1993, Pacific Seabird Group Bulletin (20) 3-12
Ornithology in Alaska formally began with the observations of Georg Wilhelm Steller during Vitus Bering's voyage of discovery in 1741. Steller's journal makes brief mention of various seabird species he encountered during his travels in the Gulf of Alaska and Aleutian Islands (Frost and Engel 1988). For more than 100...
An earth remote sensing satellite- 1 Synthetic Aperture Radar Mosaic of the Tanana River Basin in Alaska
Charles E. Wivell, Coert Olmsted, Daniel R. Steinwand, Christopher Taylor
1993, Photogrammetric Engineering and Remote Sensing (59) 527-528
Because the pixel location in a line of Synthetic Aperture Radar (SAR) image data is directly related to the distance the pixel is from the radar, terrain elevations cause large displacement errors in the geo-referenced location of the pixel. This is especially true for radar systems with small angles between...
Kappa-casein polymorphisms among cattle breeds and bison herds
M. A. Cronin, N. Cockett
1993, Animal Genetics (24) 135-138
We identified the HindIII restriction site polymorphism of K-casein in cattle reported by Pinder et al. (Animal Genetics 22, 11, 1991) and found an additonal polymorphism (RsaI) in cattle and bison. The HindIII and RsaI restriction sites were mapped and three haplotypes (alleles) were identified. Preliminary screening of 39 cattle and 71 bison revealed one allele...

We analyze intraspecific mitochondrial DNA variation in chinook salmon from drainages in the Yukon River, the Kenai River, and Oregon and California rivers; and chum salmon from the Yukon River and vancouver Island, and Washington rivers. For each species, three different portions of the mtDNA molecule were amplified seperately using...
Factors controlling the geochemical evolution of fumarolic encrustations, Valley of Ten Thousand Smokes, Alaska
L.G. Kodosky, T. E. C. Keith
1993, Journal of Volcanology and Geothermal Research (55) 185-200
Factor and canonical correlation analysis of geochemical data from eight fossil fumaroles suggest that six major factors controlled the formation and evolution of fumarolic encrustations on the 1912 ash-flow sheet in the Valley of Ten Thousand Smokes (VTTS). The six-factor solution model explains a large proportion (low of 74% for...

Natural gas hydrates of the Prudhoe Bay and Kuparuk River area, North Slope, Alaska
Timothy S. Collett
1993, American Association of Petroleum Geologists Bulletin (77) 793-812
Gas hydrates are crystalline substances composed of water and gas, mainly methane, in which a solid-water lattice accommodates gas molecules in a cage-like structure, or clathrate. These substances commonly have been regarded as a potential unconventional source of natural gas because of their enormous gas-storage capacity. Significant quantities of naturally...

A study of the genetic relationships within and among wolf packs using DNA fingerprinting and mitochondrial DNA
Niles Lehman, Peter Clarkson, L. David Mech, Thomas J. Meier, Robert K. Wayne
1992, Behavioral Ecology and Sociobiology (30) 83-94
DNA fingerprinting and mitochondrial DNA analyses have not been used in combination to study relatedness in natural populations. We present an approach that involves defining the mean fingerprint similarities among individuals thought to be unrelated because they have different mtDNA genotypes. Two classes of related individuals are identified by their...
