Courtney L. Amundson, N.J. Traub, A.J. Smith-Herron, Paul L. Flint
2016, International Journal for Parasitology: Parasites and Wildlife (5) 263-272
Climate change is occurring rapidly at high latitudes, and subsequent changes in parasite communities may have implications for hosts including wildlife and humans. Waterfowl, in particular, harbor numerous parasites and may facilitate parasite movement across broad geographic areas due to migratory movements. However, little is known about helminth community structure...

Chris D. Ivey, Christopher G. Ingersoll
2016, Environmental Toxicology and Chemistry (35) 2425-2429
Poor performance of the amphipod Hyalella azteca has been observed in exposures using reconstituted waters. Previous studies have reported success in H. azteca water-only exposures with the addition of relatively high concentrations of bromide. The present study evaluated the influence of lower environmentally representative concentrations of bromide on the response...

Renee K. Takesue
2016, Open-File Report 2016-1169
Restoration of tidal flows to formerly diked marshland can alter land-to-sea fluxes and patterns of accumulation of terrestrial sediment and organic matter, and these tidal flows can also affect existing nearshore habitats. Dikes were removed from 308 hectares (ha) of the Nisqually National Wildlife Refuge on the Nisqually River Delta...

2016, Science of the Total Environment (566-567) 320-332
To investigate interactions among disease, pesticides, water quality, and adjacent land cover, we collected samples of water, sediment, and frog tissue from 21 sites in 7 States in the United States (US) representing a variety of amphibian habitats. All samples were analyzed for > 90 pesticides and pesticide degradates, and...
Flow reconstructions in the Upper Missouri River Basin using riparian tree rings
Derek M. Schook, Jonathan M. Friedman, Sara L. Rathburn
2016, Water Resources Research (52) 8159-8173
River flow reconstructions are typically developed using tree rings from montane conifers that cannot reflect flow regulation or hydrologic inputs from the lower portions of a watershed. Incorporating lowland riparian trees may improve the accuracy of flow reconstructions when these trees are physically linked to the alluvial water table. We...

Logan H. Hodgskiss, Justin Nagy, Elliott P. Barnhart, Alfred B. Cunningham, Matthew W. Fields
2016, Algal Research (19) 63-68
Coal bed methane (CBM) production has resulted in thousands of ponds in the Powder River Basin of low-quality water in a water-challenged region. A green alga isolate, PW95, was isolated from a CBM production pond, and analysis of a partial ribosomal gene sequence indicated the isolate belongs to the Chlorococcaceae...
