Challenges facing the North American iron ore industry
J.D. Jorgenson
2005, Conference Paper, Australasian Institute of Mining and Metallurgy Publication Series
During the 20th century, the iron ore mining industries of Canada and the United States passed through several periods of transformation. The beginning of the 21st century has seen yet another period of transformation, with the economic failure of a number of steel companies, the acquisition of their facilities by...
Ice elevations and surface change on the Malaspina Glacier, Alaska
J. Sauber, B. Molnia, C. Carabajal, S. Luthcke, R. Muskett
2005, Geophysical Research Letters (32) 1-4
Here we use Ice, Cloud and land Elevation Satellite (ICESat)-derived elevations and surface characteristics to investigate the Malaspina Glacier of southern Alaska. Although there is significant elevation variability between ICESat tracks on this glacier, we were able to discern general patterns in surface elevation change by using a regional digital...
Nesting ecology and behavior of Broad-winged Hawks in moist karst forests of Puerto Rico
D.W. Hengstenberg, F. J. Vilella
2005, Journal of Raptor Research (39) 404-416
The Puerto Rican Broad-winged Hawk (Buteo platypterus brunnescens) is an endemic and endangered subspecies inhabiting upland montane forests of Puerto Rico. The reproductive ecology, behavior, and nesting habitat of the Broad-winged Hawk were studied in Ri??o Abajo Forest, Puerto Rico, from 2001-02. We observed 158 courtship displays by Broad-winged Hawks....

An updated rate-of-spread clock
Jeremy Kolaks, Keith W. Grabner, George Hartman, Bruce E. Cutter, Edward F. Loewenstein
2005, Fire Management Today (65) 26-27
Several years ago, Blank and Simard (1983) described an electronic timer, frequently referred to as a rate-of-spread (ROS) clock—a relatively simple instrument used in measuring fire spread. Although other techniques for measuring rate of spread are available (such as data loggers), the basic ROS clock remains a valuable and relatively...
The effects of summer flow augmentation on the migratory behavior and survival of juvenile Snake River fall Chinook salmon. Annual report 2003
Kenneth F. Tiffan, Craig A. Haskell, William P. Connor
2005, Report
This report summarizes results of research activities conducted in 2002 and years previous to aid in the management and recovery of fall chinook salmon Oncorhynchus tshawytscha in the Columbia River basin. The report is divided into self-standing chapters. For detailed summaries, we refer the reader to the abstracts given on...
Regulation of landslide motion by dilatancy and pore pressure feedback
R.M. Iverson
2005, Journal of Geophysical Research F: Earth Surface (110)
A new mathematical model clarifies how diverse styles and rates of landslide motion can result from regulation of Coulomb friction by dilation or contraction of water‐saturated basal shear zones. Normalization of the model equations shows that feedback due to coupling between landslide motion, shear zone volume change, and pore pressure...
Evaluation of models and data for assessing whooping crane habitat in the central Platte River, Nebraska
Adrian H. Farmer, Brian S. Cade, James W. Terrell, Jim H. Henriksen, Jeffery T. Runge
2005, Scientific Investigations Report 2005-5123
The primary objectives of this evaluation were to improve the performance of the Whooping Crane Habitat Suitability model (C4R) used by the U.S. Fish and Wildlife Service (Service) for defining the relationship between river discharge and habitat availability, and to assist the Service in implementing improved model(s) with existing hydraulic...
User manual for Blossom statistical package for R
Marian Talbert, Brian S. Cade
2005, Open-File Report 2005-1353
Blossom is an R package with functions for making statistical comparisons with distance-function based permutation tests developed by P.W. Mielke, Jr. and colleagues at Colorado State University (Mielke and Berry, 2001) and for testing parameters estimated in linear models with permutation procedures developed by B. S. Cade and colleagues at...
Visitor and community survey results for Kilauea Point National Wildlife Refuge and Lighthouse: Completion report
Natalie Sexton, Shana C. Gillette, Lynne Koontz, Susan C. Stewart, John Loomis, Katherine D. Wundrock
2005, Open-File Report 2005-1420
The U.S. Fish and Wildlife Service (USFWS) and the Central Federal Lands Highway Division of the Federal Highway Administration, U.S. Department of Transportation are currently pursuing the planning and potential design of an alternative transportation system (ATS) for Kilauea Point National Wildlife Refuge (Refuge or Kilauea Point NWR). The USFWS...
Visitor survey results for the Souris River Loop National Wildlife Refuges: Completion report
Natalie R. Sexton, Lynne Koontz, Susan C. Stewart
2005, Open-File Report 2005-1399
In support of the CCP planning effort for the Souris River Loop Refuges, the Policy Analysis and Science Assistance Branch/Fort Collins Science Center (PASA) of the U.S. Geological Survey conducted visitor surveys at three refuges in North Dakota: Des Lacs, J. Clark Salyer, and Upper Souris National Wildlife Refuges. This...
Public access management as an adaptive wildlife management tool
Douglas S. Ouren, Raymond D. Watts
2005, Open-File Report 2005-1349
Wildlife populations across the United States are benefiting from improved wildlife management techniques. However, these benefits also create new challenges including overpopulation, disease, increased winter kill, and forage degradation. These issues have become the challenges for natural resource managers and landowners. Specifically, elk (Cervus elaphus) populations in the Gunnison River...
Paleomagnetic quantification of upper-plate deformation during Miocene detachment faulting in the Mohave Mountains, Arizona
V. Pease, John W. Hillhouse, R.E. Wells
2005, Geochemistry, Geophysics, Geosystems (6)
Paleomagnetic data from Miocene (???20 Ma) volcanic rocks and dikes of west central Arizona reveal the tilt history of Proterozoic crystalline rocks in the hanging wall of the Chemehuevi-Whipple Mountains detachment fault. We obtained magnetization data from dikes and flows in two structural blocks encompassing Crossman Peak and Standard Wash...
Fuel reduction and woody debris dynamics with early season and late season prescribed fire in a Sierra Nevada mixed conifer forest
E. E. Knapp, Jon E. Keeley, E. A. Ballenger, T. J. Brennan
2005, Forest Ecology and Management (208) 383-397
Fire exclusion has led to an unnatural accumulation and greater spatial continuity of organic material on the ground in many forests. This material serves both as potential fuel for forest fires and habitat for a large array of forest species. Managers must balance...
