A Live Collection Of A Pistolgrip From Nebraska, Steven C. Schainost

Nebraska Game and Parks Commission: Staff Research Publications

Freshwater mussels (Mollusca: Bivalvia: Unionidae) are one of Nebraska's more poorly known faunas. Studies have documented the presence of 31 species of which only 19 have been found either live or freshly dead. The remaining twelve species have only been found as weathered or subfossil shells, seven of which were considered to be extirpated including the pistolgrip (Tritogonia verrucosa). While a statewide survey never has been done there is distributional information available in several published papers and unpublished reports (Baxa 1981; Hoke 1983, 1994a, 1995, 1996, 1997; Roedel 1990; Lingle 1992; Freeman and Perkins 1992, 1997; Clausen and …

Recovering Species Of Conservation Concern-Are Populations Expendable?, May Ruckelshaus, Paul Mcelhany, Michael J. Ford

United States Department of Commerce: Staff Publications

Simply mentioning the notion of species expendability may seem reprehensible, but it is a question raised often when conservation biology meets conservation practice, as in this volume. In particular, when arguing for the value of biodiversity, biologists are faced with the challenge of examining the roles that particular species might play in community function and whether there are redundancies in the functions of certain species. Does every species need to be conserved for our ecosystems to function? The question of expendability also is important in conservation planning that occurs at the species level: does every population need to be saved …

The Abundance Of Harbor Seals In The Gulf Of Alaska, Peter Boveng, John Bengtson, David Withrow, Jack Cesarone, Michael Simpkins, Kathryn Frost, John Burns

United States Department of Commerce: Staff Publications

The abundance of harbor seals (Phoca vitulina richardii) has declined in recent decades at several Alaska locations. The causes of these declines are unknown, but there is concern about the status of the populations, especially in the Gulf of Alaska. To assess the status of harbor seals in the Gulf of Alaska, we conducted aerial surveys of seals on their haul-out sites in August-September 1996. Many factors influence the propensity of seals to haul out, including tides, weather, time of day, and time of year. Because these “covariates” cannot simultaneously be controlled through survey design, we used a …

A Model Life Table For Bottlenose Dolphins (Tursiops Truncatus) From The Indian River Lagoon System, Florida, U.S.A., Megan K. Stolen, Jay Barlow

United States Department of Commerce: Staff Publications

Data gathered from 220 stranded bottlenose dolphins (Tzmiop tvuncatlls) in the Indian River Lagoon system, Florida, were used to derive a life table. Survivorship curves were fit to the data using Siler’s competing-risk model and a maximum likelihood approach. Population growth was estimated to be between r = 0.0 and 0.046 based on the observed numbers of stranded dolphins. Variance in survival rates was estimated using an individual-based, age-structured population projection model. We estimate that the overall annual mortality rate for this population was 9.8% per year. Sex-specific differences in survivorship were apparent with females outliving males. The …

Sediment-Water Interactions Affecting Dissolved-Mercury Distributions In Camp Far West Reservoir, California, James S. Kuwabara, Charles N. Alpers, Mark Marvin-Dipasquale, Brent R. Topping, James L. Carter, A. Robin Stewart, Steven V. Fend, Francis Parchaso, Gerald E. Moon, David P. Krabbenhoft

United States Geological Survey: Publications

Field and laboratory studies were conducted in April and November 2002 to provide the first direct measurements of the benthic flux of dissolved (0.2-micrometer filtered) mercury species (total and methylated forms) between the bottom sediment and water column at three sampling locations within Camp Far West Reservoir, California: one near the Bear River inlet to the reservoir, a second at a mid-reservoir site of comparable depth to the inlet site, and the third at the deepest position in the reservoir near the dam (herein referred to as the inlet, midreservoir and near-dam sites, respectively; Background, Fig. 1). Because of interest …

Quantifying The Effects Of Small-Scale Heterogeneities On Flow And Transport In Undisturbed Cores From The Hanford Formation, M. N. Pace, M. A. Mayes, P. M. Jardine, T. L. Mehlhorn, John M. Zachara, B.N. Bjornstad

United States Department of Energy: Publications

Accelerated migration of contaminants in the vadose zone has been observed beneath tank farms at the U.S. Department of Energy’s Hanford Reservation, Richland, WA. This paper focuses on quantifying hydrologic processes that control the fate and transport of contaminants in the unsaturated sediments beneath the Hanford tank farms. The experimental approach involved the use of field relevant, long-term unsaturated nonreactive transport experiments in undisturbed sediments from the Hanford Formation. Undisturbed sediment cores were collected from a laminated fine-grained sand unit within the Hanford Formation in both the vertical direction (flow cross bedding) and the horizontal direction (flow bedding parallel). Laboratory-scale …

Inhibition Of Bacterial U(Vi) Reduction By Calcium, Scott Brooks, James K. Fredrickson, Sue Carroll, David Kennedy, John M. Zachara, Andrew Plymale, Shelly Kelley, Kenneth Kemner, Scott Fendorf

United States Department of Energy: Publications

The rapid kinetics of bacterial U(VI) reduction and low solubility of uraninite (UO_2,cr) make this process an attractive option for removing uranium from groundwater. Nevertheless, conditions that may promote or inhibit U(VI) reduction are not well-defined. Recent descriptions of Ca-UO₂- CO₃ complexes indicate that these species may dominate the aqueous speciation of U(VI) in many environments. We monitored the bacterial reduction of U(VI) in bicarbonate buffered solution in the presence and absence of Ca. XAFS measurements confirmed the presence of a Ca- U(VI)-CO₃ complex in the initial solutions containing calcium. Calcium, at millimolar concentrations …

Adaptive Harvest Management: 2003 Duck Hunting Season

United States Fish and Wildlife Service: Publications

The process of setting waterfowl hunting regulations is conducted annually in the United States (Blohm 1989). This process involves a number of meetings where the status of waterfowl is reviewed by the agencies responsible for setting hunting regulations. In addition, the U.S. Fish and Wildlife Service (USFWS) publishes proposed regulations in the Federal Register to allow public comment. This document is part of a series of reports intended to support development of harvest regulations for the 2003 hunting season. Specifically, this report is intended to provide waterfowl managers and the public with information about the use of adaptive harvest management …

American Woodcock Population Status, 2003, James R. Kelley Jr.

United States Fish and Wildlife Service: Publications

Singing-ground and Wing-collection surveys were conducted to assess the population status of the American woodcock (Scolopax minor). Singing-ground Survey data indicated that the number of displaying woodcock in the Eastern and Central Regions were unchanged from 2002 (P>0.1), although the point estimates of the trends were positive. Trends from the Singing-ground Survey during 1993-03 were –1.3 and –1.6% per year for the Eastern and Central regions, respectively (P<0.05). There were long-term (1968-03) declines (P<0.01) of 2.3% per year in the Eastern Region and 1.8% per year in the Central Region. The 2002 recruitment index for the Eastern Region (1.4 immatures per adult female) was the same as the 2001 index, but was 18% below the long-term regional average. The 2002 recruitment index for the Central Region (1.6 immatures per adult female) was 17% higher than the 2001 index (1.3 immatures per adult female), and was similar to the long-term regional average. The index of daily hunting success in the Eastern Region increased slightly from 1.8 woodcock per successful hunt in 2001 to 1.9 in 2002, but seasonal hunting success declined from 6.9 woodcock per successful hunter in 2001 to 6.6 in 2002. In the Central Region, the daily success index was 2.1 woodcock per successful hunt in 2001 and 2002; but seasonal hunting success increased from 10.0 woodcock per successful hunter in 2001 to 11.0 in 2002.

Functional Implications In Apoptosis By Interferon Inducible Gene Product 1-8d, The Binding Protein To Adenovirus Preterminal Protein, Insil Joung, Peter C. Angeletti, Jeffrey A. Engler

Nebraska Center for Virology: Faculty Publications

Adenovirus (Ad) precursor to the terminal protein (pTP) plays an essential roles in the viral DNA

replication. Ad pTP serves as a primer for the synthesis of a new DNA strand during the initiation

step of replication. In addition, Ad pTP forms organized spherical replication foci on the nuclear

matrix (NM) and anchors the viral genome to the NM. Here we identified the interferon inducible

gene product 1-8D (Inid) as a pTP binding protein by using a two-hybrid screen of a HeLa cDNA

library. Of the clones obtained in this assay, nine were identical to the Inid, a 13-kDa polypeptide …

Uniformed Services University of the Health Sciences

The diseases and virulence genes associated with Shiga toxin–producing Escherichia coli (STEC) are characterized incompletely. We analyzed, by polymerase chain reaction, 82 STEC isolates collected prospectively in Montana and profiled associated illnesses by patient chart review. All E. coli O157:H7 contained stx₂-group genes, as well as eae, iha, espA, and ehxA; 84% contained stx₁. Non-O157:H7 STEC less frequently contained stx₁( P = .046 ), stx₂ (P < .001), iha (P < .001), eae, and espA (P = .039 for both), were isolated less often from patients treated in emergency departments (P = .022), and …

Novel Small Molecule Inhibitors Of Botulinum Neurotoxin A Metalloprotease Activity, James C. Burnett, James J. Schmidt, Robert G. Stafford, Rekha G. Panchal, Tam L. Nguyen, Ann R. Hermone, Jonathan L. Vennerstrom, Connor F. Mcgrath, Douglas J. Lane, Edward A. Sausville, Daniel W. Zaharevitz, Rick Gussio, Sina Bavari

United States Army: Publications

Botulinum neurotoxins (BoNTs) are among the most lethal biological substances to have been weaponized and are listed as biodefense category A agents. Currently, no small molecule (non-peptidic) therapeutics exist to counter this threat; hence, identifying and developing compounds that inhibit BoNTs is a high priority. In the present study, a high-throughput assay was used to identify small molecules that inhibit the metalloprotease activity of BoNT serotype A light chain (BoNT/A LC). All inhibitors were further verified using a HPLC-based assay. Conformational analyses of these compounds, in conjunction with molecular docking studies, were used to predict structural features that contribute to …

Herbicide Loading To Shallow Ground Water Beneath Nebraska’S Management Systems Evaluation Area, Roy F. Spalding, Darrell G. Watts, Daniel D. Snow, David A. Cassada, Mary E. Exner, James S. Schepers

Nebraska Water Center: Faculty Publications

Better management practices can counter deterioration of ground water quality. From 1991 through 1996 the influence of improved irrigation practices on ground water pesticide contamination was assessed at the Nebraska Management SystemsEvaluation Area. Three 13.4-ha corn (Zea mays L.) fields were studied: a conventional furrow-irrigated field, a surge-irrigated field and a center pivot–irrigated field, and a center pivot–irrigated alfalfa (Medicago sativa L.) field. The corn fields received one identical banded application of Bicep (atrazine [6-chloro-N-ethyl-N’-(1-methylethyl)-1,3,5-triazine-2,4,-diamine] _ metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide]) annually; the alfalfa field was untreated. Ground water samples were collected …

Expression Of Susceptibility To Fusarium Head Blight And Grain Mold In A1 And A2 Cytoplasms Of Sorghum Bicolor, James P. Stack, Jeffrey F. Pedersen

West Central Research and Extension Center, North Platte

Panicle diseases are among the major constraints to sorghum (Sorghum bicolor) production in the northern Great Plains; host plant resistance is the primary management option. However, essentially all commercial sorghum hybrids contain A₁ cytoplasm, which raises the concern about increased disease risk as a result of cytoplasmic genetic uniformity. To determine the influence of cytoplasmic background on the expression of susceptibility to panicle diseases, F₁ hybrids with four nuclear genotypes in each of two cytoplasms (A₁ and A₂) were planted in three environmentally diverse geographic locations in Nebraska. Fusarium head blight ranged in …

The Etiology And Treatment Of Nicotine Dependence: A Biopsychosocial Perspective, Lee M. Cohen, Dennis E. Mcchargue, Monica Cortez-Garland, Eric H. Prensky, Sadie Emery

Department of Psychology: Faculty Publications

Chronic use of tobacco-containing products, particularly cigarettes, remains one of the most avoidable causes of death and illness in the United States and claims the lives of more than 430,000 individuals each year (U.S. Department of Health and Human Services [DHHS], 1999). The number of tobacco-related deaths alone exceeds that of deaths due to AIDS, murders, other drugs, alcohol, car crashes, fires, and suicides combined (Centers for Disease Control and Prevention [CDC], 2002). Illnesses associated with tobacco use include, but are not limited to, laryngeal cancer, oral cancer, esophageal cancer, obstructive pulmonary disease, cardiovascular disease, intrauterine growth retardation, and low …

Family Factors That Differentiate Sexually Abused And Nonabused Adolescent Psychiatric Inpatients, Dawn H.S. Reinemann, Kevin D. Stark, Susan M. Swearer Napolitano

Department of Psychology: Faculty Publications

Sexual abuse research has traditionally focused on adult, retrospective accounts of potential correlates of abuse and their impact on functioning. However, only a few studies have examined sexually abused adolescents’ perceptions of their families, and results have proven inconclusive. This study examined whether family factors would differentiate sexually abused and nonabused adolescent psychiatric inpatients. Fifty-seven psychiatric inpatients, ages 11 to 17, who either had experienced sexual abuse or had no history of sexual victimization completed a diagnostic interview and were assessed on a variety of family indices. Results indicated that after controlling for level of depression, sexually abused adolescents could …

Standards For Science Teacher Preparation, National Science Teachers Association

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Any project intending to write education standards for national dissemination and implementation is immediately confronted with the fact that education is a state function, and that the fifty states, plus Puerto Rico, each have their own ideas about what should be taught to their children. Education, unlike many professions, is a highly political act: parents and guardians are concerned about what their children are taught; and various stakeholders have their own ideas about what constitutes a good education. Whether or not they are directly engaged in setting standards, they want to know why a particular set of standards has been …
