Michael M. Reddy, Jerry Leenheer
2011, Annals of Environmental Science (5) 41-53
Calcite crystallization rates are characterized using a constant solution composition at 25°C, pH=8.5, and calcite supersaturation (Ω) of 4.5 in the absence and presence of fulvic acids isolated from Big Soda Lake, Nevada (BSLFA), and a fulvic acid from the Suwannee River, Georgia (SRFA). Rates are also measured in the...

David W. Clow, Rachael S. Peavler, Jim Roche, Anna K. Panorska, James M. Thomas, Steve Smith
2011, Environmental Monitoring and Assessment (183) 197-215
There is concern that visitor-use associated activities, such as bathing, dish washing, wastewater production, and stock animal use near lakes and streams, could cause degradation of water quality in Yosemite National Park. A study was conducted during 2004–2007 to assess patterns in nutrient and Escherichia coli (E. coli) concentrations in...

Paul A. Buchanan, Tara L. Morgan
2011, Data Series 634
Suspended-sediment concentration data were collected by the U.S. Geological Survey in San Francisco Bay during water year 2008 (October 1, 2007–September 30, 2008). Optical sensors and water samples were used to monitor suspended-sediment concentration at two sites in Suisun Bay, two sites in Central San Francisco Bay, and one site...

2011, Scientific Investigations Report 2011-5234
Since 1992, the U.S. Geological Survey (USGS), in cooperation with the Mojave Water Agency (MWA), has constructed a series of regional water-table maps for intermittent years in a continuing effort to monitor groundwater conditions in the Mojave River and Morongo groundwater basins. The previously published data, which were used to...
Subsurface transport of orthophosphate in five agricultural watersheds, USA
Joseph L. Domagalski, Henry M. Johnson
2011, Journal of Hydrology (409) 157-171
Concentrations of dissolved orthophosphate (ortho P) in the unsaturated zone, groundwater, tile drains, and groundwater/stream water interfaces were assessed in five agricultural watersheds to determine the potential for subsurface transport. Concentrations of iron oxides were measured in the aquifer material and adsorption of ortho P on oxide surfaces was assessed...

2011, Biogeochemistry (108) 183-198
Highly resolved time series data are useful to accurately identify the timing, rate, and magnitude of solute transport in streams during hydrologically dynamic periods such as snowmelt. We used in situ optical sensors for nitrate (NO3-) and chromophoric dissolved organic matter fluorescence (FDOM) to measure surface water concentrations at 30...

Molly A. Maupin, Tamara Ivahnenko
2011, Journal of the American Water Resources Association (47)
Data from the United States Environmental Protection Agency Permit Compliance System national database were used to calculate annual total nitrogen (TN) and total phosphorus (TP) loads to surface waters from municipal and industrial facilities in six major regions of the United States for 1992, 1997, and 2002. Concentration and effluent...

U.S. Geological Survey Williston Basin Province Assessment Team
2011, Data Series 69-W
Using a geology-based assessment method, the U.S. Geological Survey estimated mean undiscovered volumes of 3.8 billion barrels of undiscovered oil, 3.7 trillion cubic feet of associated/dissolved natural gas, and 0.2 billion barrels of undiscovered natural gas liquids in the Williston Basin Province, North Dakota, Montana, and South Dakota. The U.S....
Unmarked: An R package for fitting hierarchical models of wildlife occurrence and abundance
Ian J. Fiske, Richard B. Chandler
2011, Journal of Statistical Software (43)
Ecological research uses data collection techniques that are prone to substantial and unique types of measurement error to address scientific questions about species abundance and distribution. These data collection schemes include a number of survey methods in which unmarked individuals are counted, or determined to be present, at spatially- referenced...
Winter distribution of willow flycatcher subspecies
Eben H. Paxton, Philip Unitt, Mark K. Sogge, Mary Whitfield, Paul Keim
2011, The Condor (113) 608-618
Documenting how different regions across a species' breeding and nonbreeding range are linked via migratory movements is the first step in understanding how events in one region can influence events in others and is critical to identifying conservation threats throughout a migratory animal's annual cycle. We combined two studies that...
Wind Turbines as Landscape Impediments to the Migratory Connectivity of Bats
Paul M. Cryan
2011, Environmental Law (41) 355-370
Unprecedented numbers of migratory bats are found dead beneath industrial-scale wind turbines during late summer and autumn in both North America and Europe. Prior to the wide-scale deployment of wind turbines, fatal collisions of migratory bats with anthropogenic structures were rarely reported and likely occurred very infrequently. There are no...

Jeffrey E. Lovich, Josua R. Ennen
2011, BioScience (61) 982-992
Large areas of public land are currently being permitted or evaluated for utility-scale solar energy development (USSED) in the southwestern United States, including areas with high biodiversity and protected species. However, peer-reviewed studies of the effects of USSED on wildlife are lacking. The potential effects of the construction and the...

2011, Fire Ecology (7) 81-98
We surveyed burned and unburned plots across four habitat reserves in San Diego County, California, USA, in 2005 and 2006, to assess the effects of the 2003 wildfires on the community structure and relative abundance of rodent species. The reserves each contained multiple vegetation types (coastal sage scrub, chaparral, woodland,...

Gene E. Shippentower, Carl B. Schreck, Scott A. Heppell
2011, Transactions of the American Fisheries Society (140) 1330-1339
We sought to determine whether a strontium chloride injection could be used to create a transgenerational otolith mark in steelhead Oncorhynchus mykiss. Two strontium injection trials and a survey of strontium: calcium (Sr:Ca) ratios in juvenile steelhead from various steelhead hatcheries were conducted to test the feasibility of the technique....

Janet Foley, Deana Clifford, Kevin Castle, Paul M. Cryan, Richard S. Ostfeld
2011, Conservation Biology (25) 223-231
White-nose syndrome (WNS) is a fatal disease of bats that hibernate. The etiologic agent of WNS is the fungus Geomyces destructans, which infects the skin and wing membranes. Over 1 million bats in six species in eastern North America have died from WNS since 2006, and as a result several...
West Nile virus: North American experience
Erik K. Hofmeister
2011, Integrative Zoology (6) 279-289
West Nile virus, a mosquito-vectored flavivirus of the Japanese encephalitis serogroup, was first detected in North America following an epizootic in the New York City area in 1999. In the intervening 11 years since the arrival of the virus in North America, it has crossed the contiguous USA, entered the...
Weapons testing and endangered fish coexist in Florida
Howard Jelks, Bill Tate, Frank Jordan
2011, Endangered Species Bulletin (36) 46-47
Okaloosa darters (Etheostoma okaloosae) are small fish found only in a few streams in the Florida panhandle. This species has been listed since 1973 as endangered due to habitat alteration resulting from erosion, the potential competition from brown darters (E. edwini), and a limited geographic distribution. In recent years, however,...

Michael E. Nelson, L. David Mech
2011, Canadian Field-Naturalist (125) 67-68
Wolves (Canis lupus) in northeastern Minnesota cached six radio-collars (four in winter, two in spring-summer) of 202 radio-collared White-tailed Deer (Odocoileus virginianus) they killed or consumed from 1975 to 2010. A Wolf bedded on top of one collar cached in snow. We found one collar each at a Wolf den...

2011, Environmental Science & Technology (45) 3768-3773
Natural clays have been used in ancient and modern medicine, but the mechanism(s) that make certain clays lethal against bacterial pathogens has not been identified. We have compared the depositional environments, mineralogies, and chemistries of clays that exhibit antibacterial effects on a broad spectrum of human pathogens including antibiotic resistant...
Book review: Bayesian analysis for population ecology
William A. Link
2011, American Statistician (65) 61-62
Brian Dennis described the field of ecology as “fertile, uncolonized ground for Bayesian ideas.” He continued: “The Bayesian propagule has arrived at the shore. Ecologists need to think long and hard about the consequences of a Bayesian ecology. The Bayesian outlook is a successful competitor, but is it a weed?...
