A direct immunoassay for detecting diatoms in groundwater as an indicator of the direct influence of surface water
C. E. Walker, R. M. Schrock, T. J. Reilly, A. L. Baehr
2005, Journal of Applied Phycology (17) 81-90
Groundwater under the direct influence of surface water (GWUDISW) is of concern in communities where growing public demand on groundwater resources has resulted in increased withdrawals and hydraulic stress near surface water bodies. Under these conditions, contaminants such as methyl-tert butyl ether (MTBE) and biological materials have been detected in...

Biogeochemical controls on diel cycling of stable isotopes of dissolved 02 and dissolved inorganic carbon in the Big Hole River, Montana
Stephen R. Parker, Simon R. Poulson, Chris Gammons, Michael D. DeGrandpre
2005, Environmental Science & Technology (39) 7134-7140
Rivers with high biological productivity typically show substantial increases in pH and dissolved oxygen (DO) concentration during the day and decreases at night, in response to changes in the relative rates of aquatic photosynthesis and respiration. These changes, coupled with temperature variations, may impart diel (24-h) fluctuations in the concentration...

2005, Book chapter, Techniques in aquatic toxicology
The acute aquatic toxicities (narcoses) for a range of organism types may be estimated with LSER for a large number of inorganic and organometal species, many with an accuracy at or within an order of magnitude. Optimum estimations make use of a bioavailable metal fraction and a more accurate...

In this paper, we will review past research on Escherichia coli (E. Coli) and its relationship to recreational waters. Further, we will discuss current monitoring research and future prospects for improving monitoring efficiency to protect the health of beachgoers....
Role for Fe(III) minerals in nitrate-dependent microbial U(IV) oxidation
John M. Senko, Yasser Mohamed, Thomas A. Dewers, Lee R. Krumholz
2005, Environmental Science & Technology (39) 2529-2536
Microbiological reduction of soluble U(VI) to insoluble U(IV) is a means of preventing the migration of that element in groundwater, but the presence of nitrate in U(IV)-containing sediments leads to U(IV) oxidation and remobilizaton. Nitrite or iron(III) oxyhydroxides may oxidize U(IV) under nitrate-reducing conditions, and we determined the rate and...

Geochemical controls on microbial nitrate-dependent U(IV) oxidation
John M. Senko, Joseph M. Suflita, Lee R. Krumholz
2005, Geomicrobiology Journal (22) 371-378
After reductive immobilization of uranium, the element may be oxidized and remobilized in the presence of nitrate by the activity of dissimilatory nitrate-reducing bacteria. We examined controls on microbially mediated nitrate-dependent U(IV) oxidation in landfill leachate-impacted subsurface sediments. Nitrate-dependent U(IV)-oxidizing bacteria were at least two orders of magnitude less numerous...

The use of molecular genetic tools has become increasingly important in addressing conservation issues pertaining to plants and animals. Genetic information can be used to augment studies of population dynamics and population viability, investigate systematic, refine taxonomic definitions, investigate population structure and gene flow, and document genetic diversity in a...
Managing vegetation in surface-flow wastewater-treatment wetlands for optimal treatment performance
J.S. Thullen, J.J. Sartoris, S. M. Nelson
2005, Ecological Engineering (25) 583-593
Constructed wetlands that mimic natural marshes have been used as low-cost alternatives to conventional secondary or tertiary wastewater treatment in the U.S. for at least 30 years. However, the general level of understanding of internal treatment processes and their relation to vegetation and habitat quality has not grown in proportion...
Anesthesia and blood sampling of wild big brown bats (Eptesicus fuscus) with an assessment of impacts on survival
J. Wimsatt, T. J. O'Shea, L.E. Ellison, R.D. Pearce, V.R. Price
2005, Journal of Wildlife Diseases (41) 87-95
We anesthetized and blood sampled wild big brown bats (Eptesicus fuscus) in Fort Collins, Colorado (USA) in 2001 and 2002 and assessed effects on survival. Inhalant anesthesia was delivered into a specially designed restraint and inhalation capsule that minimized handling and bite exposures. Bats were immobilized an average of 9.1±5.1...
Evaluation of models and data for assessing whooping crane habitat in the central Platte River, Nebraska

Seafloor habitats, such as seagrass beds, provide essential habitat for fish and marine mammals. For many years, the study of seagrass vitality has been a priority for scientists and resource managers working in Tampa Bay. Seafloor habitats are extremely sensitive to changes in water quality. Like a canary in a...
