Dynamics of Potamopyrgus antipodarum infestations and seasonal water temperatures in a heavily used recreational watershed in intermountain North America
Christine M. Moffitt, Christopher A. James
2012, Aquatic Invasions (7) 193-202
Following the discovery of New Zealand mudsnails, Potamopyrgus antipodarum, in the Silver Creek watershed in Idaho, we investigated the distribution and dynamics of the snail populations over two years in field surveys. Despite extensive fishing and recreational activities in the watershed, the infestations appeared limited in extent. As with other...
Design and maintenance of a network for collecting high-resolution suspended-sediment data at remote locations on rivers, with examples from the Colorado River
Ronald E. Griffiths, David J. Topping, Timothy Andrews, Glenn E. Bennett, Thomas A. Sabol, Theodore S. Melis
2012, Techniques and Methods 8-C2
Management of sand and finer sediment in fluvial settings has become increasingly important for reasons ranging from endangered-species habitat to transport of sediment-associated contaminants. In all rivers, some fraction of the suspended load is transported as washload, and some as suspended bed material. Typically, the washload is composed of silt-and-clay-size...

Magnitude of flood flows for selected annual exceedance probabilities in Rhode Island through 2010
Phillip J. Zarriello, Elizabeth A. Ahearn, Sara B. Levin
2012, Scientific Investigations Report 2012-5109
Heavy persistent rains from late February through March 2010 caused severe widespread flooding in Rhode Island that set or nearly set record flows and water levels at many long-term streamgages in the State. In response, the U.S. Geological Survey, in partnership with the Federal Emergency Management Agency, conducted a study...
Regional moisture balance control of landslide motion: implications for landslide forecasting in a changing climate
Jeffrey A. Coe
2012, Geology (40) 323-326
I correlated 12 years of annual movement of 18 points on a large, continuously moving, deep-seated landslide with a regional moisture balance index (moisture balance drought index, MBDI). I used MBDI values calculated from a combination of historical precipitation and air temperature data from A.D. 1895 to 2010, and downscaled...
Rotenone persistence model for montane streams
Peter J. Brown, Alexander V. Zale
2012, Transactions of the American Fisheries Society (141) 560-569
The efficient and effective use of rotenone is hindered by its unknown persistence in streams. Environmental conditions degrade rotenone, but current label instructions suggest fortifying the chemical along a stream based on linear distance or travel time rather than environmental conditions. Our objective was to develop models that use measurements...

Henriette Selck, Ken Drouillard, Karen Eisenreich, Albert A. Koelmans, Annemette Palmqvist, Anders Ruus, Daniel Salvito, Irv Schultz, A. Robin Stewart, Annie Weisbrod, Nico W. van den Brink, Martine van den Heuvel-Greve
2012, Integrated Environmental Assessment and Management (8) 42-63
In the regulatory context, bioaccumulation assessment is often hampered by substantial data uncertainty as well as by the poorly understood differences often observed between results from laboratory and field bioaccumulation studies. Bioaccumulation is a complex, multifaceted process, which calls for accurate error analysis. Yet, attempts to quantify and compare propagation...

Nearly half the earth's surface is occupied by dryland ecosystems, regions susceptible to reduced states of biological productivity caused by climate fluctuations. Of these regions, arid zones located at the interface between vegetated semiarid regions and biologically unproductive hyperarid zones are considered most vulnerable. The objective of this study was...
Use of vertical temperature gradients for prediction of tidal flat sediment characteristics
Jennifer L. Miselis, K. Todd Holland, Allen H. Reed, Andrei Abelev
2012, Journal of Geophysical Research C: Oceans (117) C03012-C03023
Sediment characteristics largely govern tidal flat morphologic evolution; however, conventional methods of investigating spatial variability in lithology on tidal flats are difficult to employ in these highly dynamic regions. In response, a series of laboratory experiments was designed to investigate the use of temperature diffusion toward sediment characterization. A vertical...
Vulnerability of recently recharged groundwater in principal aquifers of the United States to nitrate contamination
Jason J. Gurdak, Sharon L. Qi
2012, Environmental Science & Technology (46) 6004-6012
Recently recharged water (defined here as <60 years old) is generally the most vulnerable part of a groundwater resource to nonpoint-source nitrate contamination. Understanding at the appropriate scale the interactions of natural and anthropogenic controlling factors that influence nitrate occurrence in recently recharged groundwater is critical to support best management...

2012, Canadian Journal of Fisheries and Aquatic Sciences (69) 1056-1064
Thiamine (vitamin B1) deficiency is a global concern affecting wildlife, livestock, and humans. In Great Lakes salmonines, thiamine deficiency causes embryo mortality and is an impediment to restoration of native lake trout (Salvelinus namaycush) stocks. Thiamine deficiency in fish may result from a diet of prey with high levels of...
