2008, Waterbirds (31) 602-610
The emergence of highly pathogenic avian influenza (HPAI) H5N1 has elevated concerns about wild birds as virus hosts; however, little is known about the ecological and epidemiological factors of transmission by shorebirds. Here we summarize results for 2,773 shorebirds that were live-trapped on the Pacific coast of the United States...
Long-term dynamics of leafy spurge (Euphorbia esula) and its biocontrol agent, flea beetles in the genus Aphthona
Diane L. Larson, James B. Grace, Jennifer L. Larson
2008, Biological Control (47) 250-256
Three flea beetle species (Aphthona spp.), first introduced into North America in 1988, have come to be regarded as effective biological control organisms for leafy spurge (Euphorbia esula). The black flea beetles (Aphthona lacertosa and A. czwalinae) in particular have been shown to cause reductions in leafy spurge stem counts...

2008, FWRI Inhouse Report 2008-009
We used a structured decision-making approach to inform the decision of whether the Florida Fish and Wildlife Conservation Commission should request of the International Whooping Crane Recovery Team that additional whooping crane chicks be released into the Florida Non-Migratory Population (FNMP). Structured decision-making is an application of decision science that...

John N. Aleinikoff, Daniel R. Muhs, E. Arthur Bettis III, William C. Johnson, C. Mark Fanning, Rachel Benton
2008, GSA Bulletin (120) 1362-1377
Pb isotope compositions of detrital K-feldspars and U-Pb ages of detrital zircons are used as indicators for determining the sources of Peoria Loess deposited during the last glacial period (late Wisconsin, ca. 25–14 ka) in Nebraska and western Iowa. Our new data indicate that only loess adjacent to the Platte...

Allegra Hosford Scheirer, Leslie B. Magoon
2008, Professional Paper 1713-5
The San Joaquin Basin is a major petroleum province that forms the southern half of California’s Great Valley, a 700-km-long, asymmetrical basin that originated between a subduction zone to the west and the Sierra Nevada to the east. Sedimentary fill and tectonic structures of the San Joaquin Basin record the...
Anatomy of a shoreface sand ridge revisted using foraminifera: False Cape Shoals, Virginia/North Carolina inner shelf
Marci M. Robinson, Randolph A. McBride
2008, Continental Shelf Research (17) 2428-2441
Certain details regarding the origin and evolution of shelf sand ridges remain elusive. Knowledge of their internal stratigraphy and microfossil distribution is necessary to define the origin and to determine the processes that modify sand ridges. Fourteen vibracores from False Cape Shoal A, a well-developed shoreface-attached sand ridge on the...
Estuarine sediment transport by gravity-driven movement of the nepheloid layer, Long Island Sound
L.J. Poppe, K.Y. McMullen, S.J. Williams, J.M. Crocker, E. F. Doran
2008, Geo-Marine Letters (28) 245-254
Interpretation of sidescan-sonar imagery provides evidence that down-slope gravity-driven movement of the nepheloid layer constitutes an important mode of transporting sediment into the basins of north-central Long Island Sound, a major US East Coast estuary. In the Western Basin, this transport mechanism has formed dendritic drainage systems characterized by branching...

Chris C. Funk, Michael D. Dettinger, Joel C. Michaelsen, James P. Verdin, Molly E. Brown, Mathew Barlow, Andrew Hoell
2008, Proceedings of the National Academy of Sciences of the United States of America (105) 11081-11086
Since 1980, the number of undernourished people in eastern and southern Africa has more than doubled. Rural development stalled and rural poverty expanded during the 1990s. Population growth remains very high, and declining per-capita agricultural capacity retards progress toward Millennium Development goals. Analyses of in situ station data and satellite...

A.W. Green, D.G. Krementz
2008, Journal of Wildlife Management (72) 1328-1334
The mallard (Anas platyrhynchos) is the most harvested duck in North America. A topic of debate among hunters, especially those in Arkansas, USA, is whether wintering distributions of mallards have changed in recent years. We examined distributions of mallards in the Mississippi (MF) and Central Flyways during hunting seasons 1980-2003...

2008, International Journal of Coal Geology (76) 52-75
Coal-bed gas of the Tertiary Fort Union and Wasatch Formations in the Powder River Basin in Wyoming and Montana, U.S. was interpreted as microbial in origin by previous studies based on limited data on the gas and water composition and isotopes associated with the coal beds. To fully evaluate the...

S.K. Maxwell, M.E. Craig
2008, Geocarto International (23) 169-179
Failure of the Scan Line Corrector (SLC) on the Landsat ETM+ sensor has had a major impact on many applications that rely on continuous medium resolution imagery to meet their objectives. The United States Department of Agriculture (USDA) Cropland Data Layer (CDL) program uses Landsat imagery as the primary source...
Paleoseismic targets, seismic hazard, and urban areas in the Central and Eastern United States
R. L. Wheeler
2008, Bulletin of the Seismological Society of America (98) 1572-1580
Published geologic information from the central and eastern United States identifies 83 faults, groups of sand blows, named seismic zones, and other geological features as known or suspected products of Quaternary tectonic faulting. About one fifth of the features are known to contain faulted Quaternary materials or seismically induced liquefaction...

Chandler S. Robbins
2008, North American Bird Bander (33) 139-146
Region IV welcomed another coastal station in 2007 with a report from Chris Snook at Charleston, South Carolina. The season was hot and dry throughout Region IV except in Florida where precipitation averaged above normal. Banders blamed their poor success on the lack of cold fronts in August, September, and...

Danny Bystrak
2008, North American Bird Bander (33) 141-142
This station operates at the Patuxent Research Refuge in a powerline right-of-way that bisects an upland deciduous forest. This area has been used for this purpose since 1980, except in the years 2004-2006. Twenty-six nets are arrayed along approximately one-half mile that runs generally on an east-west orientation. The habitat is...

M.D. Koneff, J. Andrew Royle, M.C. Otto, J.S. Wortham, J.K. Bidwell
2008, Journal of Wildlife Management (72) 1641-649
We evaluated double-observer methods for aerial surveys as a means to adjust counts of waterfowl for incomplete detection. We conducted our study in eastern Canada and the northeast United States utilizing 3 aerial-survey crews flying 3 different types of fixed-wing aircraft. We reconciled counts of front- and rear-seat...

E.K. Mojica, J.M. Meyers, B.A. Millsap, K.L. Haley
2008, Wilson Journal of Ornithology (120) 304-310
We used satellite telemetry locations accurate within 1 km to identify migration routes and stopover sites of 54 migratory sub-adult Bald Eagles (Haliaeetus leucocephalus) hatched in Florida from 1997 to 2001. We measured number of days traveled during migration, path of migration, stopover time and locations, and distance traveled...

S.A. McNulty, Sam Droege, R.D. Masters
2008, Wilson Journal of Ornithology (120) 153-158
Breeding bird populations were sampled between 1954 and 1963, and 1990 and 2000 in an old-growth forest, the Natural Area of Huntington Wildlife Forest (HWF), in the Adirondack Mountains of New York. Trends were compared with data from regional North American Breeding Bird Surveys (BBS) and from a forest...

Hydrologic Drought of Water Year 2006 Compared with Four Major Drought Periods of the 20th Century in Oklahoma
Robert L. Tortorelli
2008, Scientific Investigations Report 2008-5199
Water Year 2006 (October 1, 2005, to September 30, 2006) was a year of extreme hydrologic drought and the driest year in the recent 2002-2006 drought in Oklahoma. The severity of this recent drought can be evaluated by comparing it with four previous major hydrologic droughts, water years 1929-41, 1952-56,...
