Comparison Of The Adsorbed Mercury Screening Method With Cold-Vapor Atomic Absorption Spectrophotometry For Determination Of Mercury In Soil, Donald F. Easterling, Edward S. Hovanitz, Kenneth W. Street

United States National Aeronautics and Space Administration: Publications

A field screening method for the determination of elemental mercury in environmental soil samples involves the thermal desorption of the mercury from the sample onto gold and then the thermal desorption from the gold to a goldfilm mercury vapor analyzer. This field screening method contains a large number of conditions that could be optimized for the various types of soils encountered. In this study, the conditions were optimized for the determination of mercury in silty clay materials, and the results were comparable to the coldvapor atomic absorption spectrophotometric method of determination. This paper discusses the benefits and disadvantages of employing …

Geomorphometry – Diversity In Quantitative Surface Analysis, Richard J. Pike

United States Geological Survey: Staff Publications

A widening variety of applications is diversifying geomorphometry (digital terrain modelling), the quantitative study of topography. An amalgam of earth science, mathematics, engineering and computer science, the discipline has been revolutionized by the computer manipulation of gridded terrain heights, or digital elevation models (DEMs). Its rapid expansion continues. This article reviews the remarkable diversity of recent morphometric work in 15 selected topics and discusses their significance and prospects. The quantitative analysis of industrial microsurface topography is introduced to the earth science community. The 14 other topics are Internet access to geomorphometry; global DEMs; DEM modelling of channel networks; …

Exotic Policy: An Ijc White Paper On Policies For The Prevention Of The Invasion Of The Great Lakes By Exotic Organisms, Eric Reeves

Water Law Documents

About ten years ago, the Great Lakes environmental community initiated the first action to counteract the worldwide spread of exotic organisms in ballast water. In 1988, in response to the discovery of the ruffe and the zebra mussel in the Great Lakes, the Great Lakes Fishery Commission and the International Joint Commission called upon the Canadian and United States Governments to act. In 1989, Canada issued the first voluntary ballast exchange guidelines. In 1990, the United States passed the first major piece of legislation on aquatic nuisance species, mandating consultations and studies on all pathways for aquatic invasions. And in …

Stand Structure And Productivity Of The Rhizophora Mangle In Hawaii, Evelyn F. Cox, James Allen

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Since its introduction in the early part of this century, Rhizophora mangle L. has spread extensively through most of the main islands of the Hawaiian Archipelago. We investigated the structural properties and estimated productivity of a R. mangle population at Nuupia Ponds Wildlife Management Area (NPWMA), on windward Oahu, where the mangroves were being controlled due to their propensity to overgrow archaeological sites and the habitat of endangered Hawaiian waterbirds. Mangroves within NPWMA were very dense (> 24,000 trees ha^-1) and most were relatively small (only 3.3% of the trees were ≥ 10 cm DBH). Mean basal area, …

The Relative Importance Of Patch Area And Perimeter–Area Ratio To Grassland Breeding Birds, Christopher J. Helzer, Dennis E. Jelinski

School of Natural Resources: Faculty Publications

Habitat fragmentation has been implicated as a major cause of population decline in grassland birds. We tested the hypothesis that a combination of area and shape determines the use of grassland patches by breeding birds. We compared both species richness and individual species presence in 45 wet meadow grasslands in the floodplain of the central Platte River, Nebraska. Bird data were collected through the use of belt transects and supplemented by walking and listening outside transects. Our data supported our primary hypothesis that perimeter–area ratio, which reflects both the area and shape of a patch, is the strongest predictor of …

The World Food And Agricultural Situation - A U.S. Perspective, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

It is a pleasure to be here in Minnesota at this year's Global Food and Agriculture Summit. And it is a special pleasure to share the podium today with lots of long-time friends, many of whom have forever been associated with American agriculture. would like to focus today on what kind of future might be ahead of us all as we contemplate the excitement of entering a new century. As we look back, we can only conclude that the 20th century was mighty exciting too, and assuredly challenging from an agricultural policy standpoint.

Interdisciplinary Teaching And Learning, Deborah Dezure

Professional and Organizational Development Network in Higher Education: Archives

Interdisciplinary initiatives are proliferating throughout higher education at an unprecedented rate (Edwards, 1996; Gaff and Ratcliff, 1997; Klein, 1996). They can be found in general education, replacing and augmenting distribution requirements; in emerging disciplines, such as cultural and gender studies, environmental studies, and neuroscience; in new curricular designs, such as learning communities, capstone courses, and service learning; and in the new pedagogies, such as collaborative learning, discovery and problembased learning, and the use of technology, particularly the Internet for instruction.

If we want our students to engage in complex intellectual tasks to integrate the insights of different disciplines, then lets …

Cataloging Environmental Impact Statements And Related Documents, Mary K. Bolin

University of Nebraska-Lincoln Libraries: Faculty Publications

Environmental Impact Statements (EISs) have been published by federal agencies such as the National Marine Fisheries Service, the U.S. Forest Service, the U.S. Geological Survey, and the Environmental Protection Agency, since the 1970s. These government documents can be an important source of environmental information. Some EISs are depository items, but most are not. Only a small number of each EIS is printed, and they are not always easy to identify and acquire. Their important content and fugitive nature makes it essential to catalog them to make their existence widely known. This article uses the timber sale EISs published by the …

Donald Umstadter Publications

One aspect of the complexity of mid- and high-harmonic generation in highintensity laser-plasma interactions is that nonlinear hydrodynamics is virtually always folded together with the nonlinear optical conversion process. We have partly dissected this issue in picosecond and subpicosecond interactions with preformed plasma gradients, imaging and spectrally resolving low- and mid-order harmonics. We describe spatial breakup of the picosecond beam in preformed plasmas, concomitant broaden~ng and breakup of the harmonic spectrum. presumably through self-phase modulation, together with data on the sensitivity of harmonics production efficiency to the gradient or extent of prefomed plasma. Lastly. we show preliminary data of regular …

Biodegradation Of Atrazine By Agrobacterium Radiobacter J14a And Use Of This Strain In Bioremediation Of Contaminated Soil, J. K. Struthers, K. Jayachandran, T. B. Moorman

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

We examined the ability of a soil bacterium, Agrobacterium radiobacter J14a, to degrade the herbicide atrazine under a variety of cultural conditions, and we used this bacterium to increase the biodegradation of atrazine in soils from agricultural chemical distribution sites. J14a cells grown in nitrogen-free medium with citrate and sucrose as carbon sources mineralized 94% of 50 μg of [¹⁴C-U-ring]atrazine ml^-1 in 72 h with a concurrent increase in the population size from 7.9 x 10⁵ to 5.0 x 10⁷ cells ml^-1. Under these conditions cells mineralized the [ethyl-¹⁴C]atrazine …

Decision-Making For Prairie Wetland Restorations, Susan M. Galatowitsch, Arnold G. Van Der Valk, Rachel Budelsky

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Assessments of wetland restorations in the prairie region are not done routinely and no accepted assessment framework exists. Wetland assessment protocols in the U.s. have varied over time from those emphasizing social significance to those attempting to quantify functions of wetlands from hydrogeomorphic considerations. A conceptual framework for restoration decision-making is presented that is based on optimizing wetland restoration success at both the landscape and site scales. This framework uses societal concerns, knowledge of factors that limit ecosystem recovery, and data on losses of different types of wetlands locally and regionally to establish restoration goals and guide site selection. These …

G98-1376 Drinking Water: Fluoride (Revised February 2005), Sharon Skipton, Bruce I. Dvorak

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses fluoride in domestic water supplies. Fluoride, a naturally occurring element, exists in combination with other elements as a fluoride compound and is found as a constituent of minerals in rocks and soil. When water passes through and over the soil and rock formations containing fluoride it dissolves these compounds, resulting in the small amounts of soluble fluoride present in virtually all water sources.

Reverting Conservation Reserve Program Lands To Wheat And Livestock Production: Effects On Ground Beetle (Coleoptera: Carabidae) Assemblages, B. Wade French, Norman C. Elliott, Richard C. Berberet

Entomology Papers from Other Sources

Highly erodible lands enrolled in the Conservation Reserve Program soon will revert to agricultural production. This study was designed to determine the effects of reversion of Conservation Reserve Program lands to wheat and livestock production on ground beetle assemblages. Reversion strategies included no reversion of Conservation Reserve Program grass (unmanaged bluestem), simulated grazing of Conservation Reserve Program grass (managed bluestem), minimum- tillage practices for wheat production, and no-tillage practices for wheat production. A randomized block experimental design was established with 4 replicates. More ground beetles were captured in pitfall traps in 1995 than in 1996, and abundances within years differed …

A Reintroduction Technique For Migratory Birds: Leading Canada Geese And Isolation-Reared Sandhill Cranes With Ultralight Aircraft, William A. Lishman, Tighe L. Teets, Joseph W. Duff, William J. L. Sladen, Galvin G. Shire, Kirk M. Goolsby, Wayne A. Bezner Kerr, Richard Urbanek

Proceedings of the North American Crane Workshop

No successful method for establishing self-sustaining populations of whooping cranes (Grus americana), particularly in a migration situation, has been proven. This research initiated development of a reintroduction technique using ultralight aircraft to lead cranes from a natal area along a desired route to a predetermined wintering site. Canada geese (Branta canadensis) were used in initial migration efforts. Ultralight aircraft and pilots successfully led 86 juvenile geese on 3 southbound migrations from Ontario to winter sites 640-1,312 kIn from the natal area. Of 16 1993-hatched geese that survived their first winter in Virginia and 35 1994- hatched …

Quantitation Reference Compounds And Voc Recoveries From Soils By Purge-And-Trap Gc/Ms, Brian Schumacher, Steven Ward

United States Environmental Protection Agency: Publications

Unquantified volatile organic compound (VOC) losses occur in every phase of VOC determination including sample collection, transport, storage, preparation, and analysis. Current quality assurance/quality control measures, such as surrogate spikes and internal standards, do not account for losses that occur during sample handling nor do they account for soil matrix effects. An alternate approach, the quantitation reference compound (QRC) approach, is presented that involves direction injection of the QRCs onto the soil matrix to account for any matrix effects and losses during subsequent processing steps prior to sample analysis. Final VOC quantitation is based on the QRC instead of the …

Two-Dimensional Seismic Image Of The San Andreas Fault In The Northern Gabilan Range, Central California Evidence For Fluids In The Fault Zone, C. Thurber, S. Roecker, W. Ellsworth, Y. Chen, W. Lutter, R. Sessions

United States Geological Survey: Staff Publications

A joint inversion for two-dimensional P-wave velocity (Vp), P-to-S velocity ratio (Vp/Vs), and earthquake locations along the San Andreas fault (SAF) in central California reveals a complex relationship among seismicity, fault zone structure, and the surface fault trace. A zone of low Vp andh ighV p/Vs lies beneatht he SAF surfacetr ace( SAFST), extending to a depth of about 6 km. Most of the seismic
activity along the SAF occurs at depths of 3 to 7 km in a southwest-dippingz one that roughly intersectst he SAFST, and lies near the southweset dgeo f the low Vp and high Vp/Vs zones. …
