Emerging opportunities in management of selenium contamination
Samuel N. Luoma, Theresa S. Presser
2009, Environmental Science & Technology (43) 8483-8487
The metalloid selenium (Se) has the diverse reactivity characteristic of the chalcogens in addition to organometallic behavior. Laboratory measurements indicate that Se is an acute reproductive toxicant, which makes it a concern for the environment. Yet to date, a lack of understanding on how Se species...

The crowbar chronicles and other tales
Susan E. Hough
2009, Seismological Research Letters (80) 615-616
The analysis of historical earthquakes often relies heavily on archival accounts describing the effects of shaking on structures and people. Newspaper articles are among the most common, useful, and easily found sources of information. Dramatic earthquake effects are almost certain to have made the news during historic times; the challenge...
Performance of spread spectrum Global Positioning System collars on grizzly and black bears
Charles C. Schwartz, Shannon Podruzny, Steven L. Cain, Steve Cherry
2009, Journal of Wildlife Management (73) 1174-1183
Global Positioning System (GPS) telemetry is a prevalent tool now used in the study of large mammals. Global Positioning Systems either store the data on board the collar or contain a remote-transfer system that allows for data recovery at more frequent intervals. Spread spectrum (S–S) technology is a new mode...

2009, Herpetological Conservation and Biology (4) 313-323
On the Pacific island of Guam, control of the invasive Brown Treesnake (Boiga irregularis) relies largely on methods that use mice as bait. Juvenile B. irregularis feed primarily on lizards and their eggs, but little is known about their prey preference. We conducted an experiment to investigate preferences for, and...

Robert N. Rosenfield, John Bielefeldt, Laura J. Rosenfield, Travis L. Booms, Michael A. Bozek
2009, Wilson Journal of Ornithology (121) 610-617
There are few published data on annual survival and no reports of lifetime reproduction for breeding Cooper's Hawks (Accipiter cooperii). Breeding males (n  = 105) in central and southeastern Wisconsin had an annual mortality rate of 19%, or a survival rate of 81% for birds ≤10 years of age. We did...

Robert N. Rosenfield, Stephen J. Taft, William E. Stout, Timothy G. Driscoll, David L. Evans, Michael A. Bozek
2009, Wilson Journal of Ornithology (121) 641-644
Trichomoniasis is a digestive tract disease caused by ingestion of the protozoan Trichomonas gallinae. This disease can be a significant source of mortality. No deaths of nestlings could be attributed to trichomoniasis in Cooper's Hawks (Accipiter cooperii) breeding in urban and rural environs in Wisconsin, North Dakota, and British Columbia. We...

Presettlement and modern disturbance regimes in coast redwood forests: Implications for the conservation of old-growth stands
Craig G. Lorimer, Daniel J. Porter, Mary Ann Madej, John D. Stuart, Stephen D. Veirs Jr., Steven P. Norman, Kevin L. O’Hara, William J. Libby
2009, Forest Ecology and Management (258) 1038-1054
Coast redwood (Sequoia sempervirens), a western North American conifer of ancient lineage, has a paradoxical combination of late-successional characteristics and strong adaptations to disturbance. Despite its shade tolerance and heavy dominance of the canopy on many sites, redwood saplings are uncommon in upland old-growth stands. Information needed to ensure the...
Seismic monitoring to assess performance of structures in near-real time: Recent progress
Mehmet Celebi
2009, Book chapter, Seismic risk assessment and retrofitting: With special emphasis on existing low rise structures
Earlier papers have described how observed data from classical accelerometers deployed in structures or from differential GPS with high sampling ratios deployed at roofs of tall buildings can be configured to establish seismic health monitoring of structures. In these configurations, drift ratios are the main parametric indicator of damage condition...
