Seasonal diet and habitat use of large, introduced Rainbow Trout in an Ozark Highland stream
A. W. Rodger, S. L. Wolf, T. A. Starks, J. P. Burroughs, Shannon K. Brewer
2021, North American Journal of Fisheries Management (41) 1764-1780
Stocking of Rainbow Trout Oncorhynchus mykiss commonly provides seasonal or mitigation fisheries; however, these fish are usually small and ecosystem effects are spatially or temporally limited. Yet agencies receive requests to stock Rainbow Trout in relatively natural settings (i.e., not tailwater or mitigation fisheries), where introductions may have greater ecosystem consequences. The...
Laboratory infection rates and associated mortality of juvenile Chinook Salmon (Oncorhynchus tshawytscha) from parasitic copepod (Salmincola californiensis)
Travis Neal, Michael L. Kent, Justin Sanders, Carl B. Schreck, James T. Peterson
2021, Journal of Fish Diseases (44) 1423-1434
Pacific salmon (Oncorhynchus spp.) rearing in lakes and reservoirs above dams have been known to become heavily infected with an ectoparasitic copepod (Salmincola californiensis). Little is known about the factors that affect the parasite infection prevalence and intensity. However, previous research suggests that the parasite may negatively affect the fitness and...

E. Randall Bayless
2021, Groundwater Monitoring & Remediation (41) 50-61
Laboratory evaluations of flowmeter response to flow in fractured-rock simulators are needed to improve understanding of data collected in field settings. The ability of flowmeters to accurately measure the velocity and direction of water flowing between parallel plates was used as a surrogate for instrument response...

2021, Environmental Science and Technology (55) 13770-13782
Relations between spectral absorbance and fluorescence properties of water and human-associated and fecal indicator bacteria were developed for facilitating field sensor applications to estimate wastewater contamination in waterways. Leaking wastewater conveyance infrastructure commonly contaminates receiving waters. Methods to quantify such contamination can be time consuming, expensive, and often nonspecific. Human-associated...

Effect of an algal amendment on the microbial conversion of coal to methane at different sulfate concentrations from the Powder River Basin, USA
Heidi J. Smith, Hannah S. Schweitzer, Elliott P. Barnhart, William H. Orem, Robin Gerlach, Matthew W. Fields
2021, International Journal of Coal Geology (248)
Biogenic methane is estimated to account for one-fifth of the natural gas worldwide and there is great interest in controlling methane from different sources. Biogenic coalbed methane (CBM) production relies on syntrophic associations between fermentative bacteria and methanogenic archaea to anaerobically degrade recalcitrant coal and produce methanogenic substrates. However, very...

Schistosome parasites infect more than 200 million people annually, mostly in sub-Saharan Africa, where people may be co-infected with more than one species of the parasite. Infection risk for any single species is determined, in part, by the distribution of its obligate intermediate host snail. As...

R. L. Tyne, P. H. Barry, R. Karolytė, D. J. Bryne, Justin T. Kulongoski, D.J. Hillegonds, C. J. Ballentine
2021, Chemical Geology (584)
In regions where water resources are scarce and in high demand, it is important to safeguard against contamination of groundwater aquifers by oil-field fluids (water, gas, oil). In this context, the geochemical characterisation of these fluids is critical so that anthropogenic contaminants can be readily identified. The first step...

Joseph Charles Toland, Anne Wein
2021, Water (13)
Researchers are investigating the problem of estimating households with potable water service outages soon after an earthquake. Most of these modeling approaches are computationally intensive, have large proprietary data collection requirements or lack precision, making them unfeasible for rapid assessment, prioritization, and allocation of emergency water resources in large, complex...
