Electrical conductivity of electrolytes applicable to natural waters from 0 to 100 degrees C
R. Blaine McCleskey
2011, Journal of Chemical and Engineering Data (56) 317-327
The electrical conductivities of 34 electrolyte solutions found in natural waters ranging from (10-4 to 1) mol•kg-1 in concentration and from (5 to 90) °C have been determined. High-quality electrical conductivity data for numerous electrolytes exist in the scientific literature, but the data do not span the concentration or temperature...
Aeolian and fluvial processes in dryland regions: The need for integrated studies
Jayne Belnap, Seth M. Munson, Jason P. Field
2011, Ecohydrology (4) 615-622
Aeolian and fluvial processes play a fundamental role in dryland regions of the world and have important environmental and ecological consequences from local to global scales. Although both processes operate over similar spatial and temporal scales and are likely strongly coupled in many dryland systems, aeolian and fluvial processes have...

W.E. Thogmartin, B. Potter, G. Soulliere
2011, Journal of Conservation Planning (7) 1-12
The U.S. Fish and Wildlife Service's adoption of Strategic Habitat Conservation is intended to increase the effectiveness and efficiency of conservation delivery by targeting effort in areas where biological benefits are greatest. Conservation funding has not often been allocated in accordance with explicit biological endpoints, and the gap between conservation...

Teresa J. Newton, Steven J. Zigler, James T. Rogala, Brian R. Gray, Mike Davis
2011, Aquatic Conservation: Marine and Freshwater Ecosystems (21) 122-131
1. Despite a heightened global concern for native mussels, fundamental research on mussel ecology in large rivers is lacking. These gaps in knowledge about where mussels occur, and why, are limiting habitat restoration activities. 2. Large-scale systematic surveys for native mussels in three reaches of the Upper Mississippi River...

A regional modeling framework of phosphorus sources and transport in streams of the southeastern United States
Ana Maria Garcia, Anne B. Hoos, Silvia Terziotti
2011, Journal of the American Water Resources Association (47) 991-1010
We applied the SPARROW model to estimate phosphorus transport from catchments to stream reaches and subsequent delivery to major receiving water bodies in the Southeastern United States (U.S.). We show that six source variables and five land-to-water transport variables are significant (p < 0.05) in explaining 67% of the variability in long-term...
