Bedload-surrogate monitoring technologies
John R. Gray, Jonathan B. Laronne, Jeffrey D. G. Marr
2010, Scientific Investigations Report 2010-5091
Advances in technologies for quantifying bedload fluxes and in some cases bedload size distributions in rivers show promise toward supplanting traditional physical samplers and sampling methods predicated on the collection and analysis of physical bedload samples. Four workshops held from 2002 to 2007 directly or peripherally addressed bedload-surrogate technologies, and...

Atmospheric mineral dust in dryland ecosystems: Applications of environmental magnetism
Richard L. Reynolds, Harland L. Goldstein, Mark E. Miller
2010, Geochemistry, Geophysics, Geosystems (11)
Magnetic properties of shallow (<10‐cm depth), fine‐grained surficial sediments contrast greatly with those of immediately underlying bedrock across much of the dry American Southwest. At 26 study sites in fine‐grained (<63 μm) surficial sediments isolated from alluvial inputs, isothermal remanent magnetization (IRM; mean of 67 samples = 6.72 × 10−3 Am2 kg−1) is...

Using land-cover change as dynamic variables in surface-water and water-quality models
Krista A. Karstensen, Kelly L. Warner, Anne Kuhn
2010, General Information Product 110
Land-cover data are typically used in hydrologic modeling to establish or describe land surface dynamics. This project is designed to demonstrate the use of land-cover change data in surface-water and water-quality models by incorporating land-cover as a variable condition. The project incorporates three different scenarios that vary hydrologically and geographically:...
Predators shape distribution and promote diversification of morphological defenses in Leucorrhinia , Odonata
Zlatko Petrin, Emily Gaenzle Schilling, Cyndy Loftin, Frank Johansson
2010, Evolutionary Ecology (24) 1003-1016
Predators strongly influence species assemblages and shape morphological defenses of prey. Interestingly, adaptations that constitute effective defenses against one type of predator may render the prey susceptible to other types of predators. Hence, prey may evolve different strategies to escape predation, which may facilitate adaptive radiation of prey organisms. Larvae...

John B. Ong, John W. Lane Jr., Vitaly A. Zlotnik, Todd Halihan, Eric A. White
2010, Hydrogeology Journal (18) 1539-1545
A frequency-domain electromagnetic (FDEM) survey can be used to select locations for the more quantitative and labor-intensive electrical resistivity surveys. The FDEM survey rapidly characterized the groundwater-flow directions and configured the saline plumes caused by evaporation from several groundwater-dominated lakes in the Nebraska Sand Hills, USA. The FDEM instrument was...
King eider use an income strategy for egg production: a case study for incorporating individual dietary variation into nutrient allocation research
Steffen Oppel, Abby N. Powell, Diane M. O’Brien
2010, Oecologia (164) 1-12
The use of stored nutrients for reproduction represents an important component of life-history variation. Recent studies from several species have used stable isotopes to estimate the reliance on stored body reserves in reproduction. Such approaches rely on population-level dietary endpoints to characterize stored reserves (“capital”) and current diet (“income”). Individual...
