From the mid-1970s through the mid-1980s, use of calving and summer habitats by Central Arctic herd caribou (Rangifer tarandus granti) declined near petroleum development infrastructure on Alaska's arctic coastal plain (Cameron et al. 1979; Cameron and Whitten 1980, Smith and Cameron 1983. Whitten and Cameron 1983a, 1985: Dau and Cameron...

M.L. Kennedy, P.K. Kennedy, M.A. Bogan, J.L. Waits
2002, Southwestern Naturalist (47) 335-347
The subspecific status of the Louisiana black bear (Ursus americanus luteolus) and Florida black bear (U. a. floridanus) were assessed using morphologic features to determine their distinctness in relation to one another and to the black bear (U. a. americanus). Forty-four dimensions were recorded from skulls of 125 male and...

William A. DiMichele, T.L. Phillips, W. John Nelson
2002, International Journal of Coal Geology (50) 43-72
Coal balls were collected from four coal beds in the southeastern part of the Illinois Basin. Collections were made from the Springfield, Herrin, and Baker coals in western Kentucky, and from the Danville Coal in southwestern Indiana. These four coal beds are among the principal mineable coals of the Illinois...

Daniel D. Roby, Ken Collis, Donald E. Lyons, D. P. Craig, Jessica Y. Adkins, Anne Mary Myers, Robert M. Suryan
2002, Journal of Wildlife Management (66) 662-673
We investigated the efficacy of management to reduce the impact of Caspian tern (Sterna caspia) predation on survival of juvenile salmonids (Oncorhynchus spp.) in the Columbia River estuary. Resource managers sought to relocate approximately 9,000 pairs of terns nesting on Rice Island (river km 34) to East Sand Island (river...

W. H. Poole, Robert B. Neuman
2002, Atlantic Geology (38) 109-134
Arenig strata in the Napadogan area of the Miramichi Highlands of west-central New Brunswick are similar to those of the Lunksoos anti-clinorial area of eastern Maine. Strata from both areas were deposited in a volcanic back-arc setting upon Cambrian-Tremadoc, deep-water, turbiditic quartzose strata on the northwest-facing Gander margin of Gondwana....
Sensitive high resolution ion microprobe (SHRIMP) detrital zircon geochronology provides new evidence for a hidden neoproterozoic foreland basin to the Grenville Orogen in the eastern Midwest, U.S.A

2002, Canadian Journal of Earth Sciences (39) 1505-1515
A sensitive high resolution ion microprobe (SHRIMP) was used in combination with backscattered electron (BSE) and cathodoluminescence (CL) images to determine the age of detrital zircons from sandstones in the Neoproterozoic Middle Run Formation of the eastern Midwest, United States. Eleven samples from seven drill cores of the upper part...

Thomas R. Loveland, Terry L. Sohl, S.V. Stehman, Alisa L. Gallant, K. L. Sayler, D.E. Napton
2002, Photogrammetric Engineering and Remote Sensing (68) 1091-1099
Information on the rates of land-use and land-cover change is important in addressing issues ranging from the health of aquatic resources to climate change. Unfortunately, there is a paucity of information on land-use and land-cover change except at very local levels. We describe a strategy for estimating land-cover change across...

2002, Canadian Journal of Earth Sciences (39) 1013-1051
We present new 40Ar/39Ar ages for hornblende, muscovite, and biotite from metamorphic and plutonic rocks from the YukonTanana Upland, Alaska. Integration of our data with published 40Ar/39Ar, kinematic, and metamorphic pressure (P) and temperature (T) data confirms and refines the complex interaction of metamorphism...

Brian F. Lantry, Thomas H. Eckert, Clifford P. Schneider, Jana R. Chrisman
2002, Journal of Great Lakes Research (28) 193-201
Available population and diet data on double-crested cormorant (Phalacrocorax auritus) and smallmouth bass (Micropterus dolomieui) numbers, demographics, and exploitation rates were synthesized to examine the relationship between cormorant and smallmouth bass abundance in the U.S. waters of the eastern basin of Lake Ontario....

D.T. King, T.C. Michot
2002, Waterbirds (25) 410-416
Aerial surveys of American White Pelicans (Pelecanus erythrorhynchos) were conducted over coastal Louisiana and the delta region of Mississippi on 1-2 days during December, February, and April each year from 1997 to 1999. Additional surveys were conducted in coastal Texas and Mexico during January 1998 and 1999. The numbers,...

2002, Southwestern Naturalist (47) 257-266
The pattern of geographic variation in morphologic characters of the black bear (Ursus americanus) was assessed at 13 sites in the eastern United States and Canada. Thirty measurements from 206 males and 207 females were recorded to the nearest 0.01 mm using digital calipers and subjected to principal components analysis....
Concordant paleolatitudes for Neoproterozoic ophiolitic rocks of the Trinity Complex, Klamath Mountains, California
E. A. Mankinen, N. Lindsley-Griffin, J. R. Griffin
2002, Journal of Geophysical Research B: Solid Earth (107) EPM 11-1-EPM 11-18
New paleomagnetic results from the eastern Klamath Mountains of northern California show that Neoproterozoic rocks of the Trinity ophiolitic complex and overlying Middle Devonian volcanic rocks are latitudinally concordant with cratonal North America. Combining paleomagnetic data with regional geologic and faunal evidence suggests that the Trinity Complex and related terranes...
Distribution and abundance of snowy plovers in eastern North America, the Caribbean, and the Bahamas
Leah Gorman, Susan M. Haig
2002, Journal of Field Ornithology (73) 38-52
Snowy Plovers (Charadrius alexandrinus) are small, partially migrant shorebirds that are broadly distributed across North America. Snowy Plover distribution west of the Rocky Mountains has been well described. However, distribution and abundance east of the Rocky Mountains has not received much attention despite current status and ESA listing concerns for...

James L. Bodkin, Daniel H. Monson
2002, Arctic Research of the United States (16) 31-35
Sea otters are the only fully marine otter. They share a common ancestry with the Old World land otters, but their route of dispersal to the New World is uncertain. The historic range of the species is along the northern Pacific Ocean rim, between central Baja California and the islands...

Karen Steenhof, Laura Bond, Kirk K. Bates, Lynda L. Leppert
2002, Bird Populations (6) 21-32
We estimated statewide, regional, and national trends in counts of Bald Eagles (Haliaeetus leucocephalus) along selected routes in the contiguous United States during midwinter, 1986-2000. Each January, several hundred observers collected data as part of a survey initiated by the National Wildlife Federation in 1979. To analyze these data, we...

Re-analysis of a banding study to test the effects of an experimental increase in bag limits of mourning doves
David L. Otis, Gary C. White
2002, Journal of Applied Statistics (29) 479-495
In 1966-1971, eastern US states with hunting seasons on mourning doves (Zenaida macroura) participated in a study designed to estimate the effects of bag limit increases on population survival rates. More than 400 000 adult and juvenile birds were banded and released during this period, and subsequent harvest and return...
Some aspects of resource uncertainty and their economic consequences in assessment of the 1002 Area of the Arctic National Wildlife Refuge
Emil D. Attanasi, John H. Schuenemeyer
2002, Natural Resources Research (11) 109-120
Exploration ventures in frontier areas have high risks. Before committing to them, firms prepare regional resource assessments to evaluate the potential payoffs. With no historical basis for directly estimating size distribution of undiscovered accumulations, reservoir attribute probability distributions can be assessed subjectively and used to project...

David P. Hill, P. Dawson, M.J.S. Johnston, A.D. Pitt, G. Biasi, K. Smith
2002, Geophysical Research Letters (29) 8-1-8-4
Detection of three very‐long‐period (VLP) volcanic earthquakes beneath Mammoth Mountain emphasizes that magmatic processes continue to be active beneath this young, eastern California volcano. These VLP earthquakes, which occurred in October 1996 and July and August 2000, appear as bell‐shaped pulses with durations of one to two...

Calving caribou (Rangifer tarandus) of the Central Arctic herd, Alaska, have avoided the infrastructure associated with the complex of petroleum development areas from Prudhoe Bay to Kuparuk (Cameron et al. 1992, Nellemann and Cameron 1998, and Section 4 of this document). Calving females of the Porcupine caribou herd may similarly...

Deformation associated with an earthquake swarm on 12 September 1999 in the Upper East Rift Zone of Kilauea Volcano was recorded by continuous GPS receivers and by borehole tiltmeters. Analyses of campaign GPS, leveling data, and interferometric synthetic aperture radar (InSAR) data from the ERS-2 satellite also reveal significant deformation...
