Juliane B. Brown, David P. Thoma
2012, Scientific Investigations Report 2012-5043
Nutrients are a nationally recognized concern for water quality of streams, rivers, groundwater, and water bodies. Nutrient impairment is documented by the U.S. Environmental Protection Agency as a primary cause of degradation in lakes and reservoirs, and nutrients are related to organic enrichment and oxygen depletion, which is an important...
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...
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...

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...
Variance of discharge estimates sampled using acoustic Doppler current profilers from moving boats
Carlos M. Garcia, Leticia Tarrab, Kevin Oberg, Ricardo Szupiany, Mariano I. Cantero
2012, Journal of Hydraulic Engineering
This paper presents a model for quantifying the random errors (i.e., variance) of acoustic Doppler current profiler (ADCP) discharge measurements from moving boats for different sampling times. The model focuses on the random processes in the sampled flow field and has been developed using statistical methods currently available for uncertainty...
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, Environmental Science & Technology (46) 2746-2754
The potential presence of steroid hormones in runoff from sites where biosolids have been used as agricultural fertilizers is an environmental concern. A study was conducted to assess the potential for runoff of seventeen different hormones and two sterols, including androgens, estrogens, and progestogens from agricultural test plots. The field...
Effects of trophic level and metamorphosis on discrimination of hydrogen isotopes in a plant-herbivore system
Jacob M. Peters, Nathan Wolf, Craig A. Stricker, Timothy R. Collier, Carlos Martinez del Rio
2012, PLoS ONE (7)
The use of stable isotopes in ecological studies requires that we know the magnitude of discrimination factors between consumer and element sources. The causes of variation in discrimination factors for carbon and nitrogen have been relatively well studied. In contrast, the discrimination factors for hydrogen have rarely been measured. We...

Edaphic, salinity, and stand structural trends in chronosequences of native and non-native dominated riparian forests along the Colorado River, USA
David M. Merritt, Patrick B. Shafroth
2012, Biological Invasions (14) 2665-2685
Tamarix spp. are introduced shrubs that have become among the most abundant woody plants growing along western North American rivers. We sought to empirically test the long-held belief that Tamarix actively displaces native species through elevating soil salinity via salt exudation. We measured chemical and physical attributes of soils (e.g., salinity, major cations...

Exploring changes in the spatial distribution of stream baseflow generation during a seasonal recession
R.A. Payn, M.N. Gooseff, B.L. McGlynn, K.E. Bencala, S.M. Wondzell
2012, Water Resources Research (48)
Relating watershed structure to streamflow generation is a primary focus of hydrology. However, comparisons of longitudinal variability in stream discharge with adjacent valley structure have been rare, resulting in poor understanding of the distribution of the hydrologic mechanisms that cause variability in streamflow generation along valleys. This study explores detailed...
