Many ecosystems worldwide are dominated by introduced plant species, leading to loss of biodiversity and ecosystem function. A common but rarely tested assumption is that these plants are more abundant in introduced vs. native communities, because ecological or evolutionary-based shifts in populations underlie invasion success. Here, data for 26 herbaceous...
A beaded collar for dual micro GPS/VHF transmitter attachment to nutria
G. Michael Haramis, T. S. White
2011, Mammalia (75) 79-82
We report on the development of an approximately 85-g beaded collar for dual micro GPS/VHF transmitter attachment to semi-aquatic nutria (Myocastor coypus). Prototype collars were tested on captive nutria and refined during field trials. Central to the design was novel use of the VHF transmitter antenna as a collar. A...
Agricultural herbicide transport in a first-order intermittent stream, Nebraska, USA
J. R. Vogel, J.I. Linard
2011, Applied Engineering in Agriculture (27) 63-74
The behavior of herbicides in surface waters is a function of many variables, including scale of the watershed, physical and chemical properties of the herbicide, physical and chemical properties of the soil, rainfall intensity, and time of year. In this study, the transport of 6 herbicides and 12 herbicide degradates...

2011, Environmental Toxicology and Chemistry (30) 1213-1222
The acute oral toxicity of the anticoagulant rodenticide diphacinone was found to be over 20 times greater in American kestrels (Falco sparverius; median lethal dose 96.8 mg/kg body weight) compared with Northern bobwhite (Colinus virginianus) and mallards (Anas platyrhynchos). Modest evidence of internal bleeding was observed at necropsy, although histological...
Comparison of main-shock and aftershock fragility curves developed for New Zealand and US buildings
S.R. Uma, H. Ryu, N. Luco, A.B. Liel, M. Raghunandan
2011, Conference Paper, Proceedings of the Ninth Pacific Conference on Earthquake Engineering: Building an earthquake resilient society
Seismic risk assessment involves the development of fragility functions to express the relationship between ground motion intensity and damage potential. In evaluating the risk associated with the building inventory in a region, it is essential to capture 'actual' characteristics of the buildings and group them so that 'generic building types'...
Acute Toxicity of Sodium Fluorescein to Ashy Pebblesnails Fluminicola fuscus
Kelly A. Stockton, Christine M. Moffitt, David L. Blew, C. Neil Farmer
2011, Report
Water resource agencies and groundwater scientists use fluorescein dyes to trace ground water flows that supply surface waters that may contain threatened or endangered mollusk species. Since little is known of the toxicity of sodium fluorescein to mollusks, we tested the toxicity of sodium fluorescein to the ashy pebblesnail Fluminicola...

Comparing the role of fuel breaks across southern California national forests
Alexandra D. Syphard, Jon E. Keeley, Teresa J. Brennan
2011, Forest Ecology and Management (261) 2038-2048
Fuel treatment of wildland vegetation is the primary approach advocated for mitigating fire risk at the wildland–urban interface (WUI), but little systematic research has been conducted to understand what role fuel treatments play in controlling large fires, which factors influence this role, or how the role of fuel treatments may...
Complementary models of tree species-soil relationships in old-growth temperate forests
Alison Cross, Steven S. Perakis
2011, Ecosystems (14) 248-260
Ecosystem-level studies identify plant–soil feedbacks as important controls on soil nutrient availability, particularly for nitrogen and phosphorus. Although site- and species-specific studies of tree species–soil relationships are relatively common, comparatively fewer studies consider multiple co-existing species in old-growth forests across a range of sites that vary in underlying soil fertility....

2011, Book chapter, Greater Sage-Grouse: Ecology and Conservation of a Landscape Species and Its Habitats
Recent analyses of Greater Sage-Grouse (Centrocercus urophasianus) populations indicate substantial declines in many areas but relatively stable populations in other portions of the species? range. Sagebrush (Artemisia spp.) habitats neces-sary to support sage-grouse are being burned by large wildfires, invaded by nonnative plants, and developed for energy resources (gas, oil,...

Aggregate resource availability in the conterminous United States, including suggestions for addressing shortages, quality, and environmental concerns
William H. Langer
2011, Open-File Report 2011-1119
One-third of America's major roads are in poor or mediocre condition, and over one-quarter of the bridges are either structurally deficient or functionally obsolete. A 70-percent increase in annual aggregate production may be required to upgrade the transportation infrastructure. Natural aggregate is widespread throughout the conterminous United States, but the...

A Holocene record of endogenic iron and manganese precipitation, isotopic composition of endogenic carbonate, and vegetation history in a lake-fen complex in northwestern Minnesota
Walter E. Dean, Lisa A. Doner
2011, Open-File Report 2011-1106
Little Shingobee Lake and Fen are part of an extensive network of lakes and wetlands in the Shingobee River headwaters area of northwestern Minnesota. Prior to about 9800 radiocarbon years, most of the lakes in the Shingobee watershed area were interconnected to form glacial Lake Willobee. From 9800 to 7700...

James K. Otton
2011, Open-File Report 2011-1140
Studies of the natural environment in the Grants Mineral Belt in northwestern New Mexico have been conducted since the 1930s; however, few such investigations predate uranium mining and milling operations, which began in the early 1950s. This report provides an annotated bibliography of reports that describe the hydrology and geochemistry...
Estimated 2008 groundwater potentiometric surface and predevelopment to 2008 water-level change in the Santa Fe Group aquifer system in the Albuquerque area, central New Mexico
Sarah E. Falk, Laura M. Bexfield, Scott K. Anderholm
2011, Scientific Investigations Map 3162
The water-supply requirements of the Albuquerque metropolitan area of central New Mexico have historically been met almost exclusively by groundwater withdrawal from the Santa Fe Group aquifer system. Previous studies have indicated that the large quantity of groundwater withdrawal relative to recharge has resulted in water-level declines in the aquifer...
Estimated probabilities, volumes, and inundation area depths of potential postwildfire debris flows from Carbonate, Slate, Raspberry, and Milton Creeks, near Marble, Gunnison County, Colorado
Michael R. Stevens, Jennifer L. Flynn, Verlin C. Stephens, Kristine L. Verdin
2011, Scientific Investigations Report 2011-5047
During 2009, the U.S. Geological Survey, in cooperation with Gunnison County, initiated a study to estimate the potential for postwildfire debris flows to occur in the drainage basins occupied by Carbonate, Slate, Raspberry, and Milton Creeks near Marble, Colorado. Currently (2010), these drainage basins are unburned but could be burned...

Valerie J. Paul, Ilsa B. Kuffner, Linda J. Walters, Raphael Ritson-Williams, Kevin S. Beach, Mikel A. Becerro
2011, Marine Ecology Progress Series (426) 161-170
Competition between corals and macroalgae is often assumed to occur on reefs, especially those that have undergone shifts from coral to algal dominance; however, data examining these competitive interactions, especially during the early life-history stages of corals, are scarce. We conducted a series of field and outdoor seawater-table experiments to...
