2015, Biological Conservation (186) 225-232
Renewable energy is expanding quickly with sometimes dramatic impacts to species and ecosystems. To understand the degree to which sensitive species may be impacted by renewable energy projects, it is informative to know how much space individuals use and how that space may overlap with planned development. We used global...

Lester J. Williams, Eve L. Kuniansky
2015, Professional Paper 1807
The hydrogeologic framework for the Floridan aquifer system has been revised throughout its extent in Florida and parts of Georgia, Alabama, and South Carolina. The updated framework generally conforms to the original framework established by the U.S. Geological Survey in the 1980s, except for adjustments made to the internal boundaries...

Russell W. Perry, Patricia L. Brandes, Jon R. Burau, Philip T. Sandstrom, John R. Skalski
2015, Transactions of the American Fisheries Society (144) 445-455
Juvenile Chinook Salmon Oncorhynchus tshawytscha emigrating from natal tributaries of the Sacramento River, California, must negotiate the Sacramento-San Joaquin River Delta (hereafter, the Delta), a complex network of natural and man-made channels linking the Sacramento River with San Francisco Bay. Fish that enter the interior and southern Delta—the region to...

Dong-Hun Lee, Mia Kim Torchetti, Kevin Winker, S. Ip, David E. Swayne, Chang-Seon Song
2015, Journal of Virology (89) 6521-6524
Phylogenetic network analysis and understanding of waterfowl migration patterns suggest the Eurasian H5N8 clade 2.3.4.4 avian influenza virus emerged in late 2013 in China, spread in early 2014 to South Korea and Japan, and reached Siberia and Beringia by summer 2014 via migratory birds. Three genetically distinct subgroups emerged and...

Michael D. Samuel, Jeffrey S. Hall, Justin D. Brown, Diana R. Goldberg, S. Ip, Vasily V. Baranyuk
2015, Ecological Applications (25) 1851-1859
Wild water birds are the natural reservoir for low-pathogenic avian influenza viruses (AIV). However, our ability to investigate the epizootiology of AIV in these migratory populations is challenging, and despite intensive worldwide surveillance, remains poorly understood. We conducted a cross-sectional, retrospective analysis in Pacific Flyway lesser snow geese Chen caerulescens...
A chronicle of a killer alga in the west: Ecology, assessment, and management of Prymnesium parvum blooms
D. L. Roelke, Aaron Barkoh, Bryan W. Brooks, J. P. Grover, K. D. Hambright, John W. LaClaire II, Peter D. R. Moeller, Reynaldo Patino
2015, Hydrobiologia (764) 29-50
Since the mid-1980s, fish-killing blooms of Prymnesium parvum spread throughout the USA. In the south central USA, P. parvum blooms have commonly spanned hundreds of kilometers. There is much evidence that physiological stress brought on by inorganic nutrient limitation enhances toxicity. Other factors influence toxin production as well, such as...

Erik A. Smith, Stephen M. Westenbroek
2015, Scientific Investigations Report 2015-5038
Groundwater recharge is one of the most difficult components of a water budget to ascertain, yet is an important boundary condition necessary for the quantification of water resources. In Minnesota, improved estimates of recharge are necessary because approximately 75 percent of drinking water and 90 percent of agricultural irrigation water...

Marc L. Buursink, Steven M. Cahan, Peter D. Warwick
2015, Scientific Investigations Report 2015-5021
Following the geologic basin-scale assessment of technically accessible carbon dioxide storage resources in onshore areas and State waters of the United States, the U.S. Geological Survey estimated that an area of about 130 million acres (or about 200,000 square miles) of Federal lands overlies these storage resources. Consequently, about 18...
