Prevalence Of Eimeria (Apicomplexa: Eimeriidae) In Reintroduced Gunnison's Prairie Dogs (Cynomys Gunnisoni), M. M. Ryan, K. H. Decker, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Fecal samples from 54 Gunnison’s prairie dogs (Cynomys gunnisoni) from Albuquerque, NM were analyzed for the presence of coccidia and all were positive. They were then relocated to an abandoned prairie dog town on the Sevilleta Long Term Ecological Research (LTER) site. Six Eimeria species, E. callospermophili, E. cynomysis, E. pseudospermophili (new host record), E. spermophili, E. ludoviciani and E. vilasi (new host record) were found in Albuquerque animals, but only two species, E. callospermophili and E. vilasi were present in relocated hosts. A significant (P < 0.05) reduction was seen in the prevalence of E. vilasi (72% vs. 13%) and in the prevalence of infections …

Phylogey Of Steinernema Travassos, 1927 (Cephalobina: Steinnematidae) Inferred From Ribosomal Dna Sequences And Morphological Characters, S. Patricia Stock, James F. Campbell, Steven A. Nadler

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Entomopathogenic nematodes in Steinernema, together with their symbiont bacteria Xenorhabdus, are obligate and lethal parasites of insects that can provide effective biological control of some important lepidopteran, dipteran, and coleopteran pests of commercial crops. Phylogenetic relationships among 21 Steinernema species were estimated using 28S ribosomal DNA (rDNA) sequences and morphological characters. Sequences of the rDNA internal transcribed spacers were obtained to provide additional molecular characters to resolve relationships among Steinernema carpocapsae, Steinernema scapterisci, Steinernema siamkayai, and Steinernema monticolum. Four equally parsimonious trees resulted from combined analysis of 28S sequences and 22 morphological characters. Clades inferred from …

Uneasy Unions: Quality Effects Of Rye Chromatin Transfers To Wheat, Robert A. Graybosch

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

A number of genes of agronomic importance have been transferred from rye (Seale cereale L.) to its close relative, common bread wheat (Triticum aestivum L). Largely through the production of interspecific chromosomal translocation and substitution lines, rye chromatin now rides within the genome of a large number of wheat breeding lines and cultivars. Rye chromosomal materials have been used to transfer resistance genes to fungal pathogens, especially rusts and powdery mildew, resistance to insect pests, and in some cases, may enhance grain yield, grain yield stability, and grain protein content. Unfortunately, the transfer of some rye chromosomal materials …

Net Grassland Carbon Flux Over A Subambient To Superambient Co2 Gradient, P. C. Mielnick, W. A. Dugas, H. B. Johnson, H. W. Polley, J. Sanabria

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

Increasing atmospheric CO₂ concentrations may have a profound effect on the structure and function of plant communities. A previously grazed, central Texas grassland was exposed to a 200-µmol mol^-1 to 550 µmol mol^-1 CO₂ gradient from March to mid-December in 1998 and 1999 using two, 60-m long, polyethylene-covered chambers built directly onto the site. One chamber was operated at subambient CO₂ concentrations (200-360 µmol mol^-1 daytime) and the other was regulated at superambient concentrations (360-550 µmol mol^-1). Continuous CO₂ gradients were maintained in each chamber by photosynthesis during the day and …

Research Needs Concerning Non-Target Impacts Of Biological Control Introductions, K.R. Hopper

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

Two workshops were held in 1999 on research needs concerning non-target impacts of biological control introductions. One took place on the Internet for 9 months, and the other in Montpellier, France, for 1 day. Altogether, over 200 researchers from over 30 countries participated, representing a wide variety of viewpoints on the issues involved. The deliberations of these workshops are summarized here. Both workshops highlighted the need for retrospective studies to: (i) identify cases of significant non-target impacts; (ii) explore mechanisms involved when such impacts are found; (iii) evaluate the reliability of host-range testing protocols; and (iv) determine whether and under …

Meiotic Stability, Chloroplast Dna Polymorphisms, And Morphological Traits Of Upland X Lowland Switchgrass Reciprocal Hybrids, J. M. Martinez-Reyna, Kenneth P. Vogel, Carol Caha, Donald J. Lee

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

Switchgrass (Panicum virgatum L.) has two cytotypes or cytoplasm types, L and U, that are associated with the lowland and upland ecotypes, respectively. The L cytotypes are tetraploids while the U cytotypes can be either tetraploids or octaploids. The objective of this research was to characterize meiotic stability of reciprocal crosses of U and L plants as indicated by chromosome pairing at meiosis and to determine the mode of inheritance of chloroplast DNA (cpDNA) in the hybrids of these cytotypes. Morphological markers that characterize the parents and hybrids also were investigated to confirm that progeny were true hybrids. Reciprocal …

Soil Property Changes During Conversion From Perennial Vegetation To Annual Cropping, Brian J. Wienhold, Donald L. Tanaka

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

Management practices for conversion of land supporting perennial vegetation to crop production are needed. Effect of haying (hayed or not hayed), cropping (annual crop with no-tillage, minimum tillage, or conventional tillage, and no-tilled perennial crop), and N fertilization (0 or 67 kg ha^-1) on soil properties were measured in 1995 and 1997 at a Conservation Reserve Program (CRP) site in North Dakota having an Amor loam (Fine-loamy, mixed, superactive, frigid, Typic Haplustoll) soil in a spring wheat (Triticum aestivum L.), winter wheat, pea (Pisum sativum L.) rotation. Soil physical properties were not affected negatively by the …

Nutrients In Runoff Following The Application Of Swine Manure To Interrill Areas, John E. Gilley, Bahman Eghball, Brian J. Wienhold, Phillip S. Miller

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

The P content of swine manure can be reduced through the addition of feed supplements or the use of selected corn hybrids. This study was conducted to compare interrill runoff losses of P and N from three soils following the application of swine manure obtained from selected diets. The soils used in this investigation included a Hersh sandy loam, Pierre silty clay, and Sharpsburg silt loam. Simulated rainfall was applied during both initial and wet runs to a soil pan on which swine manure produced from low phytate corn (LPC), phytase added to the diet (PHY), or a traditional corn …

Functional Classification Of Swine Manure Management Systems Based On Effluent And Gas Emission Characteristics, J. A. Zahn, J. L. Hatfield, D. A. Laird, T. T. Hart, Y. S. Do, A. A. Dispirito

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

Gaseous emissions from swine (Sus scrofa) manure storage systems represent a concern to air quality due to the potential effects of hydrogen sulfide, ammonia, methane, and volatile organic compounds on environmnental quality and human health. The lack of knowledge concerning functional aspects of swine manure management systems has been a major obstacle in the development and optimization of emission abatement technologies for these point sources. In this study a classification system based on gas emission characteristics and effluent concentrations of total phosphorus (P) and total sulfur (S) was devised and tested on 29 swine manure management systems in …

Testing The River Continuum Concept: Exploring Ecological Processes In The Wheeling Creek Watershed., Deborah Ann Carpenter

Graduate Theses, Dissertations, and Problem Reports (ETD)

The river continuum concept (RCC) asserts that the biological community in a stream system is largely regulated by geomorphological factors (Vannote, et al., 1980, 131). The concept states that community structure in natural stream systems is structured in order to capitalize on the most efficient energy utilization throughout. The objective of this research is to test the RCC in the Wheeling Creek watershed of northern West Virginia and southwestern Pennsylvania and to compare the results with those hypothesized under the RCC. One of the strongest criticisms of the RCC is that the continuum assumes an undisturbed stream system. Anomalies found …

Oxidative Metabolism In Plant/Bacteria Interactions: Characterization Of The Oxygen Uptake Response Of Bacteria, C. Jacyn Baker, Norton Mock, Kenneth L. Deahl, Bryan Bailey, Daniel P. Roberts

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

An increase in oxygen uptake has been previously described in plant cell suspensions treated with bacteria or bacterial elicitors. These studies, regarding oxygen uptake, have all been undertaken from the perspective of the host plant cell reacting to the invading pathogen. In contrast, here we describe and characterize an increase in oxygen uptake by bacterial cells in response to plant suspensions or autoclaved plant cell filtrates. Autoclaved plant cell filtrates stimulated bacterial oxygen uptake by as much as sevenfold within a few minutes after addition. This oxygen uptake response was proportional to both the concentration of the plant cell filtrate …

Oxidative Metabolism In Plant/Bacteria Interactions: Characterization Of A Unique Oxygen Uptake Response Of Potato Suspension Cells, C. Jacyn Baker, E. W. Orlandi, Kenneth L. Deahl

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

Plant suspension cells have been shown to respond to bacteria or microbial elicitors by producing active oxygen as well as increasing oxygen uptake. Here we characterize a unique two stage oxygen uptake response of potato suspension cells to heat-killed bacteria. Stage 1 occurred within minutes after the addition of heat-killed bacteria; the potato suspension cells responded with a rapid increase in oxygen uptake and reached a steady state approximately 50 % greater than the initial basal rate. Stage 2 began 20-30 min after this new steady state was achieved and was characterized by a slow increase in the oxygen uptake …

Induction Of Defense Responses In Tobacco By The Protein Nep1 From Fusarium Oxysporum, James C. Jennings, Patricia C. Apel-Birkhold, Norton M. Mock, C. Jacyn Baker, James D. Anderson, Bryan A. Bailey

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

Fusarium oxysporum produces a 24-kDa protein, Nep1, which induces necrosis and ethylene production in leaves of many dicot plant species. Detached Nicotiana tabacum L. cv. Xanthi leaves respond with concentration-dependent necrosis after infiltration with Nep1 or when Nep1 is taken up by the vascular tissue. This response follows the induction of ethylene biosynthesis and accumulation of ACC synthase and ACC oxidase transcripts. Pretreating the leaves with 100 µl/l ethylene prior to elicitation enhanced Nep1-induced ethylene production. Nep1 (208 nM) causes extensive necrosis of mature tobacco leaf tissue when applied to Xanthi tobacco as a foliar spray (129 ml/m²). …

Conservation And Evaluation Of Natural Enemies In Ipm Systems For Bemisia Tabaci, Steven E. Naranjo

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

Conservation biological control emphasizes the preservation and enhancement of natural enemies and is the cornerstone of all approaches to biological control. This review critically examines recent and current research efforts in conservation biological control by predators and parasitoids of Bemisia tabaci worldwide. A large number of natural enemy species have been identified from many agricultural systems. Further research has demonstrated that these natural enemies may act along with other mortality agents to inflict high levels of mortality on populations of B. tabaci. Less effort has been placed on determining the factors constraining or potentially enhancing biological control. The widespread …

Managing Crop Residue With Green Manure, Urea, And Tillage In A Rice–Wheat Rotation, Milkha S. Aulakh, T. S. Khera, John W. Doran, Kevin F. Bronson

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

Most double-crop grain farmers in South Asia remove or burn cropresidue to facilitate seedbed preparation and to avoid possible yield reductions. This results in loss of soil organic matter (SOM) and nutrients. In this study, we determined whether incorporating wheat (Triticum aestivum L.) residue, rice (Oryza sativa L.) residue, and sesbania (Sesbania aculeta L.) green manure with urea fertilizer N in a rice–wheat cropping system can improve grain yields, N use efficiency, and SOM. We incorporated wheat residue (6 Mg ha^-1, C/N = 94), rice residue (6 Mg ha^-1, C/N = 63), or …

Like A Banana Tree : Towards A Model Of Children In Disasters : An Exploration Of An Anthropological Problem, Jennie Anne Ricarda Marten

Theses : Honours

There is currently an emerging literature on the anthropology of disasters, and also an emergent literature on the new anthropology of childhood and children. Despite an extensive search, no significant body of literature on the anthropology of children in natural event based disasters could be found. A central focus of this thesis will be interrogate this gap through a documentary search, to ascertain what factors might influence the absence of children in the anthropology of disasters. To achieve this, the study defines and conceptualizes both the anthropology of disasters and the anthropology of children. Recent research shows that children are …

The Psychosocial Well-Being Of Children From Fly-In/Fly-Out Mining Families, Anne Margaret Sibbel

Theses : Honours

The children of fly-in/fly-out (FIFO) mining employees are exposed to the risk factors for depressive disorders of regular father absence associated with hazardous employment conditions, together with disruptions to family routines. In the absence of previous research in this area, this exploratory study sought to determine whether the levels of depressive symptomatology, anxiety and perceptions of family function of 30 primary school-aged children whose fathers were in FIFO employment were less healthy than those of a Control Group of 30 children whose fathers did not have FIFO employment. The mothers' perceptions of family function were also compared. The children were …

Ecological Observations Of Juvenile Head-Started Western Pond Turtles (Clemmys Marmorata Marmorata) In Their First Season In The Wild, Steven Lee Clark

Dissertations and Theses

This project studies 16 juvenile, western pond turtles that were head-started as part of a species recovery program. To my knowledge, no studies have focused solely on juvenile western pond turtles. This study focuses on the turtles’ ecology in their first season in the wild. Radio telemetry was used to study the turtles’ survival, habitat use, behavior and movement.

All study animals survived. Turtles were found to choose aquatic habitat with 81 %-100% floating vegetative cover. Data suggest that refugia was the most important benefit of floating vegetation. All overwintered in upland sites after brief stays in the ponds. Home …

Altered Operant Responding For Motor Reinforcement And The Determination Of Benchmark Doses Following Perinatal Exposure To Low-Level 2,3,7,8-Tetrachlorodibenzo-P-Dioxin, Vincent P. Markowski, Grazyna Zareba, Sander Stern, Christopher Cox, Bernard Weiss

Psychology

Pregnant Holtzman rats were exposed to a single oral dose of 0, 20, 60, or 180 ng/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on the 18th day of gestation. Their adult female offspring were trained to respond on a lever for brief opportunities to run in specially designed running wheels. Once they had begun responding on a fixed-ratio 1 (FR1) schedule of reinforcement, the fixed-ratio requirement for lever pressing was increased at five-session intervals to values of FR2, FR5, FR10, FR20, and FR30. We examined vaginal cytology after each behavior session to track estrous cyclicity. Under each of the FR values, perinatal TCDD exposure …

Probing The Capabilities Of Copper Complexes With Nitrogen And Sulfur Containing Macrocyclic Ligands As Aziridination Catalysts, Jonathan Natkin

Honors Theses

Aziridines are three-membered rings containing one nitrogen atom. They are useful as synthetic intermediates in many organic reactions. Much work has been devoted to synthesizing their analogs, cyclopropanes and epoxides, but little work has been done on the aziridination reaction. This study endeavored to probe the efficiencies of novel copper aziridination catalysts with N3 and S3 macrocyclic ligands compared to an NS2 analog for the reaction with the nitrene precursor (N-(paratosylsulfonyl) imino)phenyliodinane, PhINTs, and the olefin styrene. The nitrogen containing catalyst complex gave higher yields than the sulfur containing catalyst complex. Both ligands were found to decrease the yield of …

Resistance Exercise Training Attenuates Wasting Of The Edl Muscle In Mice Bearing The Colon-26 Adenocarcinoma, Sadeeka Al-Majid, Donna O. Mccarthy

College of Nursing Faculty Research and Publications

Progressive wasting of skeletal muscle is a significant side effect of malignancy. Perturbations in protein metabolism contribute to this state of wasting. Resistance exercise increases protein synthesis and mass of healthy muscles and counteracts muscle wasting associated with several catabolic conditions. It is not known whether resistance exercise training can counteract cancer-induced muscle wasting. This study examined the effect of resistance exercise training on muscle mass and protein content in 9 mice bearing the colon-26 adenocarcinoma. The dorsiflexor (extensor digitorum longus [EDL] and tibialis anterior) and plantar flexor (soleus, plantaris, and gastrocnemius) muscles of 1 leg of the tumor-bearing and …

Cancer-Induced Fatigue And Skeletal Muscle Wasting: The Role Of Exercise, Sadeeka Al-Majid, Donna O. Mccarthy

College of Nursing Faculty Research and Publications

Fatigue is the most frequently reported symptom by cancer patients. Many of these patients perceive fatigue as the most distressing symptom associated with their illness because it imposes limitations on their physical activity level. Skeletal muscle wasting, which occurs as part of cancer cachexia, is one of the mechanisms that contribute to fatigue. Cancer induced skeletal muscle wasting may occur despite normal food intake and is not prevented by nutritional supplementation. Evidence suggests that endurance exercise ameliorates cancer-related fatigue. There is no compelling evidence to support that exercise induced reduction in fatigue is related to preservation of muscle mass. Resistance …

The Arctic Environmental Protection Strategy, Arctic Council And Multilateral Environmental Initiatives: Tinkering While The Arctic Marine Environment Totters, David Vanderzwaag, Robert Huebert, Stacey Ferrara

Articles, Book Chapters, & Popular Press

The Arctic marine environment is not pristine, as commonly imagined, but is facing numerous pressures,' the most serious arguably coming from outside the region. Melting of sea ice, linked to global warming, threatens the long-term survival of various species including polar bears and has potential to seriously disrupt ocean currents. Persistent organic pollutants (POPs), including pesticides, industrial compounds and combustion by-products, are transported via air and water currents from regions outside the Arctic and become concentrated in the fatty tissues of animals." The pollutants threaten not only the well being of wildlife but the health of northern residents heavily dependent …
