Determining baselines and variability of elements in plants and soils near the Kenai National Wildlife Refuge, Alaska
J.G. Crock, R. C. Severson, L. P. Gough
1992, Water, Air, & Soil Pollution (63) 253-271
Recent investigations on the Kenai Peninsula had two major objectives: (1) to establish elemental baseline concentrations ranges for native vegetation and soils; and, (2) to determine the sampling density required for preparing stable regional geochemical maps for various elements in native plants and soils. These objectives were accomplished using an...

The timing of wing molt in tundra swans: energetic and non-energetic constraints
S.L. Earnst
1992, Condor (94) 847-856
Date of wing molt initiation, based on the regression of tenth primary length on capture date, was calculated for breeding and nonbreeding Tundra Swans (Cygnus columbianus columbianus) on the Colville River Delta, Alaska. Breeding females initiated wing molt significantly later than breeding males and nonbreeding males and females; the molt...
Survival of cackling Canada geese, 1982-1988

1992, Journal of Wildlife Management (56) 63-73
We estimated seasonal and annual survival rates of cackling Canada geese (Branta canadensis minima) for the period 1982-1989 to identify periods of high mortality and assess effects of harvest management decisions. We tested hypotheses about age- and sex specific variation in survival, seasonal variation in survival rates, and variation in...

Intraspecific mitochondrial DNA variation in North American cervids
M. A. Cronin
1992, Journal of Mammalogy (73) 70-82
Intraspecific variation in mitochondrial DNA of North American cervids was assessed with restriction enzymes to determine relationships among populations and subspecies. No variation was detected in moose (Alces alces) and little in elk (Cervus elaphus). Caribou (Rangifer tarandus), white-tailed deer (Odocoileus virginianus), and mule deer (Odocoileus hemionus) possessed considerable...
Depositional history, nannofossil biostratigraphy, and correlation of Argo Abyssal Plain Sites 765 and 261
Julie A. Dumoulin, Paul R. Bown
Sondra K. Stewart, Diana Kennett, Elsa K. Mazzullo, editor(s)
1992, Proceedings of the Ocean Drilling Program: Scientific Results 123-1
Sediments from the Argo Abyssal Plain (AAP), northwest of Australia, are the oldest known from the Indian Ocean and were recovered from ODP Site 765 and DSDP Site 261. New biostratigraphic and sedimentologic data from these sites, as well as reinterpretations of earlier findings, indicate that basal sediments at both...
Change-in-ratio methods for estimating population size
Mark S. Udevitz, Kenneth H. Pollock
Dale R. McCullough, Reginald H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations
Change-in-ratio (CIR) methods can provide an effective, low cost approach for estimating the size of wildlife populations. They rely on being able to observe changes in proportions of population subclasses that result from the removal of a known number of individuals from the population. These methods were first introduced in...
Sedimentary history of the Tethyan margins of eastern Gondwana during the Mesozoic
James G. Ogg, Felix Gradstein, Julie A. Dumoulin, Massimo Sarti, Paul Brown
1992, Book chapter, Geophysical Monograph Series, Volume 70: Synthesis of results from scientific drilling in the Indian Ocean
A composite Mesozoic geological history for the Gondwana margins to the Eastern Tethys Ocean can be assembled from stratigraphic successions on the Australian and Himalayan margins and from drill sites of Ocean Drilling Program Legs 122 and 123. During the Triassic, this region drifted northwards, entering tropical paleolatitudes during the...
Lower Cretaceous smarl turbidites of the Argo Abyssal Plain, Indian Ocean
Julie A. Dumoulin
Sondra K. Stewart, Diana Kennett, Elsa K. Mazzullo, editor(s)
1992, Proceedings of the Ocean Drilling Program: Scientific Results 123-5
Sediments recovered during Ocean Drilling Program (ODP) Leg 123 from the Argo Abyssal Plain (AAP) consist largely of turbidites derived from the adjacent Australian continental margin. The oldest abundant turbidites are Valanginian-Aptian in age and have a mixed (smarl) composition; they contain subequal amounts of calcareous and siliceous biogenic components,...

Breeding distribution of the Black Turnstone
Colleen M. Handel, Robert E. Gill Jr.
1992, The Wilson Bulletin (104) 122-135
Eighty-five percent of the world population of Black Turnstones (Arenaria melanocephala) nest on the central Yukon-Kuskokwim Delta, Alaska, 65% concentrated in a narrow band of salt grass, graminoid, and dwarf shrub meadows within two km of the...
Change-in-ratio estimators for populations with more than two subclasses
Mark S. Udevitz, Kenneth H. Pollock
1991, Biometrics (47) 1531-1546
Change-in-ratio methods have been developed to estimate the size of populations with two or three population subclasses. Most of these methods require the often unreasonable assumption of equal sampling probabilities for individuals in all subclasses. This paper presents new models based on the weaker assumption that ratios of sampling probabilities...
A comparison of aerial and boat-based surveys for marbled murrelets in southeast Alaska, July 23-28, 1991
John F. Piatt, Bruce Conant, Chris Iverson
1991, Report
Aerial and boat-based surveys for Marbled Murrelets (Brachyramphus marmoratus) were conducted simultaneously over short transect distances (ca. 2 km) in three different areas of the Alexander Archipelago to assess the accuracy and variability of aerial counts compared to boat-based counts. Additional aerial surveys were conducted over a wider geographic area...
Elevations and distances in the United States

1991, Report
The information in this booklet was compiled to answer inquiries received by the U.S. Geological Survey from students; teachers; writers; editors; publishers of encyclopedias, almanacs, and other reference books; and people in many other fields of work. The elevations of features and distances between points in the United States were...
Denali Park wolf studies: Implications for Yellowstone
L. David Mech, Thomas J. Meier, John W. Burch
1991, Conference Paper, Transactions of the 56th North American Wildlife and Natural Resources Conference
The Northern Rocky Mountain Wolf Recovery Plan approved by the U.S. Fish and Wildlife Service (1987) recommends re-establishment of wolves (Canis lupus) in Yellowstone National Park. Bills proposing wolf re-establishment in the Park have been introduced into the U.S. House and Senate. However, several questions have been raised about the...
Observations at convergent margins concerning sediment subduction, subduction erosion, and the growth of continental crust
Roland E. von Huene, D.W. Scholl
1991, Reviews of Geophysics (29) 279-316
At ocean margins where two plates converge, the oceanic plate sinks or is subducted beneath an upper one topped by a layer of terrestrial crust. This crust is constructed of continental or island arc material. The subduction process either builds juvenile masses of terrestrial crust through arc volcanism or new...
