In Alaska, sea ducks winter in coastal habitats at remote, non-industrialized areas, as well as in proximity to human communities and industrial activity. We evaluated prevalence and characteristics of Escherichia coli strains in faecal samples of Steller's eiders (Polysticta stelleri; n = 122) and harlequin ducks (Histrionicus histrionicus; n = 21) at an industrialized site and Steller's eiders...
Asbestos
Robert Virta
2011, Book chapter, Kirk-Othmer Encyclopedia of Chemical Technology
The term asbestos is a generic designation referring usually to six types of naturally occurring mineral fibers that are or have been commercially exploited. These fibers belong to two mineral groups: serpentines and amphiboles. The serpentine group is represented by a single asbestiform variety-chrysotile. There also are five commercial asbestiform...
Land cover classification for Fanno Creek, Oregon
Steven Sobieszczyk
2011, Report
Fanno Creek is a tributary to the Tualatin River and flows though parts of the southwest Portland metropolitan area. The stream is heavily influenced by urban runoff and shows characteristic flashy streamflow and poor water quality commonly associated with urban streams. This data set represents the floodplain land cover as...

Understory response to varying fire frequencies after 20 years of prescribed burning in an upland oak forest
J.A. Burton, S.W. Hallgren, S.D. Fuhlendorf, David M. Leslie Jr.
2011, Plant Ecology (212) 1513-1525
Ecosystems in the eastern United States that were shaped by fire over thousands of years of anthropogenic burning recently have been subjected to fire suppression resulting in significant changes in vegetation composition and structure and encroachment by invasive species. Renewed interest in use of fire to manage such ecosystems will...
Black-footed ferrets and Siberian polecats as ecological surrogates and ecological equivalents
E. Biggins, Louis R. Hanebury, B.J. Miller, R. A. Powell
2011, Journal of Mammalogy (92) 710-720
Ecologically equivalent species serve similar functions in different communities, and an ecological surrogate species can be used as a substitute for an equivalent species in a community. Siberian polecats (Mustela eversmanii) and black-footed ferrets (M. nigripes) have long been considered ecological equivalents. Polecats also have been used as investigational surrogates...

C.C. Carabajal, D.J. Harding, J.-P. Boy, Jeffrey J. Danielson, D.B. Gesch, V.P. Suchdeo
2011, Conference Paper, Proceedings of SPIE - The International Society for Optical Engineering
Supported by NASA's Earth Surface and Interior (ESI) Program, we are producing a global set of Ground Control Points (GCPs) derived from the Ice, Cloud and land Elevation Satellite (ICESat) altimetry data. From February of 2003, to October of 2009, ICESat obtained nearly global measurements of land topography (+/- 86deg...
Trap style influences wild pig behavior and trapping success
B.L. Williams, R.W. Holtfreter, S.S. Ditchkoff, J. Barry Grand
2011, Journal of Wildlife Management (75) 432-436
Despite the efforts of many natural resource professionals, wild pig (Sus scrofa) populations are expanding in many areas of the world. Although many creative techniques for controlling pig populations are being explored, trapping has been and still is the most commonly used method of population control for many public and...

Patterns of coral disease across the Hawaiian Archipelago: Relating disease to environment
G.S. Aeby, G.J. Williams, E.C. Franklin, J. Kenyon, E.F. Cox, S. Coles, Thierry M. Work
2011, PLoS ONE (6)
In Hawaii, coral reefs occur across a gradient of biological (host abundance), climatic (sea surface temperature anomalies) and anthropogenic conditions from the human-impacted reefs of the main Hawaiian Islands (MHI) to the pristine reefs of the northwestern Hawaiian Islands (NWHI). Coral disease surveys were conducted at 142 sites from across...
Changes in monoterpene mixing ratios during summer storms in rural New Hampshire (USA)

2011, Atmospheric Chemistry and Physics (11) 11465-11476
Monoterpenes are an important class of biogenic hydrocarbons that influence ambient air quality and are a principle source of secondary organic aerosol (SOA). Emitted from vegetation, monoterpenes are a product of photosynthesis and act as a response to a variety of environmental factors. Most parameterizations of monoterpene emissions are based...
Age, genesis, and paleoclimatic interpretation of the Sangamon/Loveland complex in the Lower Mississippi Valley, USA
H. W. Markewich, D.A. Wysocki, M.J. Pavich, E.M. Rutledge
2011, Geological Society of America Bulletin (123) 21-39
For more than a century, the Sangamon paleosol (the Sangamon) has been an integral part of geologic and pedologic investigations in the central United States, including the Upper Mississippi and Lower Missouri River Valleys. Compositional, pedologic, micromorphologic, stratigraphic, and age data indicate that the prominent reddish paleosol developed in silt-rich...

High-resolution aeromagnetic surveys of the Cascade Range and Yakima fold and thrust belt (YFTB), Washington, provide insights on tectonic connections between forearc and back-arc regions of the Cascadia convergent margin. Magnetic surveys were measured at a nominal altitude of 250 m above terrain and along flight lines spaced 400 m...

J. Cappelle, S. A. Iverson, John Y. Takekawa, S. H. Newman, T. Dodman, N. Gaidet
2011, Ostrich (82) 17-26
We provide recommendations for implementing telemetry studies on waterfowl on the basis of our experience in a tracking study conducted in three countries of sub-Saharan Africa. The aim of the study was to document movements by duck species identified as priority candidates for the potential spread of avian influenza. Our...
Toward a consistent model for strain accrual and release for the New Madrid Seismic Zone, central United States
S. E. Hough, M. Page
2011, Journal of Geophysical Research B: Solid Earth (116)
At the heart of the conundrum of seismogenesis in the New Madrid Seismic Zone is the apparently substantial discrepancy between low strain rate and high recent seismic moment release. In this study we revisit the magnitudes of the four principal 1811–1812 earthquakes using intensity values determined from individual assessments from...
Molecular detection of vertebrates in stream water: A demonstration using rocky mountain tailed frogs and Idaho giant salamanders
C.S. Goldberg, D. S. Pilliod, R.S. Arkle, L.P. Waits
2011, PLoS ONE (6)
Stream ecosystems harbor many secretive and imperiled species, and studies of vertebrates in these systems face the challenges of relatively low detection rates and high costs. Environmental DNA (eDNA) has recently been confirmed as a sensitive and efficient tool for documenting aquatic vertebrates in wetlands and in a large river...
Stratigraphic, sedimentologic, and dendrogeomorphic analyses of rapid floodplain formation along the Rio Grande in Big Bend National Park, Texas
David J. Dean, Linda J. Scott, Patrick B. Shafroth, John C. Schmidt
2011, Geological Society of America Bulletin (123) 1908-1925
The channel of the lower Rio Grande in the Big Bend region rapidly narrows during years of low mean and peak flow. We conducted stratigraphic, sedimentologic, and dendrogeomorphic analyses within two long floodplain trenches to precisely reconstruct the timing and processes of recent floodplain formation. We show that the channel...
An occurrence of the protocetid whale "Eocetus" wardii in the middle Eocene Piney Point Formation of Virginia
Robert E. Weems, Lucy E. Edwards, Jason E. Osborne, A.A. Alford
2011, Journal of Paleontology (85) 271-278
Two protocetid whale vertebrae, here referred to “Eocetus” wardii, have been recovered from the riverbed of the Pamunkey River in east-central Virginia. Neither bone was found in situ, but both were found with lumps of lithified matrix cemented to their surfaces. Most of this matrix was removed and processed for...
