K.L. Laidre, R.J. Jameson, E. Gurarie, S.J. Jeffries, H. Allen
2009, Journal of Mammalogy (90) 906-917
Sea otter (Enhydra lutris kenyoni) movements, home range, and activity budgets were described from data collected during very-high-frequency radiotelemetry studies of 75 individuals on the outer coast of Washington State between 1992 and 1999. Sea otters were located at least once per week from 22 accessible sites along the coast....
Thiamine content of eggs and lengths of coho salmon (Oncorhynchus kisutch) in relation to abundance of alewife (Alosa pseudoharengus) in eastern Lake ontario, 2003 to 2006
H. G. Ketola, J. Rinchard, R. O'Gorman, L.J. Begnoche, D.L. Bishop, A.W. Greulich
2009, Journal of Freshwater Ecology (24) 247-254
Early mortality syndrome in fry of Great Lakes salmonines is linked to reduced levels of thiamine in eggs, which reflects maternal consumption of forage fishes such as alewife (Alosa pseudoharengus) that contain thiaminase, an enzyme that destroys thiamine. We assessed annual variations in abundance and condition of alewives and thiamine...

2009, Applied Geochemistry (24) 1500-1511
A soil geochemical survey was conducted in a 27,000-km2 study area of northern California that includes the Sierra Nevada Mountains, the Sacramento Valley, and the northern Coast Range. The results show that soil geochemistry in the Sacramento Valley is controlled primarily by the transport and weathering of parent material from...
PAHs underfoot: Contaminated dust from coal-tar sealcoated pavement is widespread in the United States
P. C. Van Metre, B.J. Mahler, J.T. Wilson
2009, Environmental Science & Technology (43) 20-25
We reported in 2005 that runoff from parking lots treated with coal-tar-based sealcoat was a major source of polycyclic aromatic hydrocarbons (PAHs) to streams in Austin, Texas. Here we present new data from nine U. S. cities that show nationwide patterns in concentrations of PAHs associated with sealcoat Dust was...
A spatial model to prioritize sagebrush landscapes in the intermountain west (U.S.A.) for restoration
C.W. Meinke, S.T. Knick, D.A. Pyke
2009, Restoration Ecology (17) 652-659
The ecological integrity of Sagebrush (Artemisia spp.) ecosystems in the Intermountain West (U.S.A.) has been diminished by synergistic relationships among human activities, spread of invasive plants, and altered disturbance regimes. An aggressive effort to restore Sagebrush habitats is necessary if we are to stabilize or improve current habitat trajectories and...

K. David Newell, Saibal Bhattacharya, M. Scott Sears
2009, Oil & Gas Journal (107) 35-44
Several low-btu gas plays can be defined by mapping gas quality by geological horizon in the Midcontinent. Some of the more inviting plays include Permian strata west of the Central Kansas uplift and on the eastern flank of Hugoton field and Mississippi chat and other pays that subcrop beneath (and...

40Ar/39Ar dating of biotite from felsic orthogneiss recovered from the -3890-foot level of the Island Beach State Park (IBSP) well beneath the outer New Jersey Coastal Plain was accomplished using CO2 laser incremental-heating techniques. Over 75% of the Ar released from the incremental-heating experiment form a well-behaved plateau with a...

Asbury H. Sallenger Jr., C. W. Wright, Kara Doran, K. Guy, Karen Morgan
2009, Special Paper of the Geological Society of America (460) 127-135
Hurricane Rita devastated gulf-front communities along the western Louisiana coast in 2005. LIDAR (light detection and ranging) topographic surveys and aerial photography collected before and after the storm showed the loss of every structure within the community of Holly Beach. Average shoreline change along western Louisiana's 140-km-long impacted shore was...

Future intrusion of oxygenated glacial meltwaters into the Fennoscandian shield: A possibility to consider in performance assessments for nuclear-waste disposal sites?
Pierre Glynn
2008, Book chapter, Review of SKB's safety assessment SR-Can: Contributions in support of SKI's and SSI's review by external consultants
Provost et al. (1998) and Glynn and Voss (1999; also published in Glynn et al., 1999) considered the possibility that during future glaciations, oxygenated glacial meltwaters from two- to three-kilometer thick ice sheets could potentially intrude to the 500 m depth of planned nuclear-waste repositories. This possibility has been of...

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...

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...
