Predicting lesser scaup wetland use during spring migration in eastern South Dakota
S.N. Kahara, S. R. Chipps
2009, Great Plains Research (19) 157-167
The relative influence of physical, chemical, and biotic wetland characteristics on wetland use by spring migrating lesser scaup (Aythya affinis [Eyton]; hereafter "scaup") is not well understood. We compared characteristics of used and unused wetlands in eastern South Dakota. Used wetlands were larger (>2 ha; P = 0.05), with higher...
Water uptake and nutrient concentrations under a floodplain oak savanna during a non-flood period, lower Cedar River, Iowa
K. E. Schilling, P. Jacobson
2009, Hydrological Processes (23) 3006-3016
Floodplains during non-flood periods are less well documented than when flooding occurs, but non-flood periods offer opportunities to investigate vegetation controls on water and nutrient cycling. In this study, we characterized water uptake and nutrient concentration patterns from 2005 to 2007 under an oak savanna located on the floodplain of...
Effects of fire temperature on the physical and chemical characteristics of the ash from two plots of Cork oak (Quercus Suber)
X. Ubeda, P. Pereira, L. Outeiro, D.A. Martin
2009, Land Degradation and Development (20) 589-608
Cork oak, (Quercus suber) is widely distributed in the Mediterranean region, an area subject to frequent fires. The ash produced by burning can have impacts on the soil status and water resources that can differ according to the temperature reached during fire and the characteristics of the litter, defined as...

2009, Journal of Experimental Marine Biology and Ecology (381) S204-S215
The Chesapeake 2000 Agreement committed its state and federal signatories to “define the water quality conditions necessary to protect aquatic living resources” in the Chesapeake Bay (USA) and its tidal tributaries. Hypoxia is one of the key water quality issues addressed as a result of the above Agreement. This paper...

The weathering of a sulfide orebody: Speciation and fate of some potential contaminants
A. Courtin-Nomade, C. Grosbois, M.A. Marcus, S.C. Fakra, J.-M. Beny, A. L. Foster
2009, Canadian Mineralogist (47) 493-508
Various potentially toxic trace elements such as As, Cu, Pb and Zn have been remobilized by the weathering of a sulfide orebody that was only partially mined at Leona Heights, California. As a result, this body has both natural and anthropogeni- cally modified weathering profiles only 500 m apart. The...

2009, Geological Society Special Publication 11-19
A transect of four sites (U1325, U1326, U1327 and U1329) across the northern Cascadia margin was established during Integrated Ocean Drilling Program Expedition 311 to study the occurrence and formation of gas hydrate in accretionary complexes. In addition to the transect sites, a fifth site (U1328) was established at a...
Wide-area estimates of saltcedar (Tamarix spp.) evapotranspiration on the lower Colorado River measured by heat balance and remote sensing methods
Pamela L. Nagler, Kiyomi Morino, Kamel Didan, J. Erker, John Osterberg, Kevin R. Hultine, Edward P. Glenn
2009, Ecohydrology (2) 18-33
In many places along the lower Colorado River, saltcedar (Tamarix spp) has replaced the native shrubs and trees, including arrowweed, mesquite, cottonwood and willows. Some have advocated that by removing saltcedar, we could save water and create environments more favourable to these native species. To test these assumptions we compared sap...
A Miocene to Pleistocene climate and elevation record of the Sierra Nevada (California)
A. Mulch, Andrei M. Sarna-Wojcicki, M. E. Perkins, C. P. Chamberlain
2009, PNAS (105) 6819-6824
Orographic precipitation of Pacific-sourced moisture creates a rain shadow across the central part of the Sierra Nevada (California) that contrasts with the southern part of the range, where seasonal monsoonal precipitation sourced to the south obscures this rain shadow effect. Orographic rainout systematically lowers the hydrogen isotope composition of precipitation...

Basin characteristics for selected streamflow-gaging stations in and near West Virginia
Katherine S. Paybins
2008, Open-File Report 2008-1087
Basin characteristics have long been used to develop equations describing streamflow. In the past, flow equations used in West Virginia were based on a few hand-calculated basin characteristics. More recently, the use of a Geographic Information System (GIS) to generate basin characteristics from existing datasets has refined the process for...

Estimating sediment discharge: Appendix D
John R. Gray, Francisco J. M. Simões
2008, Book chapter, Sedimentation engineering: processes, measurements, modeling, and practice
Sediment-discharge measurements usually are available on a discrete or periodic basis. However, estimates of sediment transport often are needed for unmeasured periods, such as when daily or annual sediment-discharge values are sought, or when estimates of transport rates for unmeasured or hypothetical flows are required. Selected methods for estimating suspended-sediment,...
