Developing Relative Abundance Techniques (Rats) For Monitoring Rodent Populations, Desely A. Whisson, Richard M. Engeman, Kellie Collins Jan 2005

Developing Relative Abundance Techniques (Rats) For Monitoring Rodent Populations, Desely A. Whisson, Richard M. Engeman, Kellie Collins

United States Department of Agriculture Wildlife Services: Staff Publications

Accurate density estimates of rodents are frequently difficult or cost-prohibitive to determine. Thus, a number of techniques (track plates, monitoring blocks, chew cards/sticks, apple slice index, trapping) are often used to index rodent populations. Theoretically, the sensitivity of these indexing techniques could be improved if they applied continuous measurements rather than simple binary measurements (presence/absence). Development of a relative abundance technique that is simple to apply and sensitive to changes in population density is critical for the operational management of rodent pests. In addition to providing a quantitative measure of abundance with statistical parameters, an indexing technique that does not …


The Impact Of Disease In The American White Pelican In North America, Tonie Rocke, Kathryn Converse, Carol Meteyer, Bob Mclean Jan 2005

The Impact Of Disease In The American White Pelican In North America, Tonie Rocke, Kathryn Converse, Carol Meteyer, Bob Mclean

United States Department of Agriculture Wildlife Services: Staff Publications

Records of reported die-offs of the American White Pelican ( Pelicanus erythrorhynchos ) held by the U.S. Geological Survey National Wildlife Health Center from 1978 through 2003 indicate that type C botulism (caused by Clostridium botulinum ) was the major cause of mortality. In 1996, over 15,000 birds, including 8,500 American White Pelicans, were estimated to have died from type C botulism at the Salton Sea in California. This was the largest documented die-off of any pelican species and was estimated to represent 15-20% of the western metapopulation. This event was also notable in that it was the first time …

Husbandry Of Wild-Caught Greater Sage-Grouse, Paul Oesterle, Robert Mclean, Michael Dunbar, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

This study reports the first successful husbandry and breeding in captivity of wild-caught greater sage-grouse (Ccntroccrcus urophasianus). In October 2003, 2 1 hatch-year greater sage-grouse were trapped in northwestern Nevada and transported to Fort Collins, Colorado. We held grouse in pens at the United States Department of Agriculture's National Wildlife Research Center for 8 months. We offered a varied diet, including native food items such as sagebrush (Arternisia tridentata and A. tripartita) and yarrow (Achilles millefolium). We housed grouse in a large flight pen and allowed to them freerange as one flock. Mortdlity rate was 16.7%. Several of the grouse …

Stability Of The Tranquilizer Drug Propionylpromazine Hydrochloride In Formulated Products, Thomas M. Primus, Bruce A. Kimball, Jerome Hurley, John J. Johnston, Sherm Blom, Peter J. Savarie Jan 2005

Stability Of The Tranquilizer Drug Propionylpromazine Hydrochloride In Formulated Products, Thomas M. Primus, Bruce A. Kimball, Jerome Hurley, John J. Johnston, Sherm Blom, Peter J. Savarie

United States Department of Agriculture Wildlife Services: Staff Publications

An analytical method to evaluate propionylpromazine hydrochloride (PPZHCl) in tranquilizer formulations was developed using high-performance liquid chromatography (HPLC). During analysis of aged quality-control samples, a previously unreported chromatographic response was observed at a shorter retention time than PPZHCl. Further investigation of formulations stored in trap tap devices at temperatures ranging from 5 to 40 ◦C during field trials at four different locations confirmed the degradation of the active ingredient. Further investigation using HPLC/tandem mass spectrometry revealed two to five degradates, with the major degradates being oxidation products of the active ingredient, PPZHCl. As PPZHCl formulations must be stable when stored …


Coyote Movements And Social Structure Along A Cryptic Population Genetic Subdivision, Benjamin N. Sacks, Brian R. Mitchell, Christen L. Williams, Holly B. Ernest Jan 2005

Coyote Movements And Social Structure Along A Cryptic Population Genetic Subdivision, Benjamin N. Sacks, Brian R. Mitchell, Christen L. Williams, Holly B. Ernest

United States Department of Agriculture Wildlife Services: Staff Publications

A recent region-wide study determined that the central California coyote ( Canis latrans ) population was genetically subdivided according to habitat bioregions, supporting the hypothesis that coyotes exhibit a dispersal bias toward their natal habitat type. Here, we further investigated this hypothesis using radio-collared coyotes captured on a 150-km 2 study site on the border of (i.e. overlapping) two bioregions (Great Valley and Cascade Mountains). As predicted, most coyotes were assigned (based on a priori genetic criteria) to genetic clusters corresponding to one of these two bioregions. All of those assigned to the Great Valley genetic cluster were caught in …

From The Field: Field Searches Versus Vaginal Implant Translocating Elk Calves, Nathan W. Seward, David S. Maehr, Jonathan W. Gassett, John J. Cox, Jeffrey L. Larkin Jan 2005

From The Field: Field Searches Versus Vaginal Implant Translocating Elk Calves, Nathan W. Seward, David S. Maehr, Jonathan W. Gassett, John J. Cox, Jeffrey L. Larkin

United States Department of Agriculture Wildlife Services: Staff Publications

We compared the utility of vaginal implant transmitters (VITs) and field searches for locating elk (Cervus elaphus) calves in southeastern Kentucky during the spring of 2001. Retention of VITs among 40 adult females ranged from 1–276 days (x - =61.6±8.4 [SE] days). Approximately half of the transmitters (n=19) were expelled prematurely or malfunctioned. Two of 37 (5%) transmitters in translocated females performed as designed and led to calf capture. We captured more calves (n=9 in 2001; n=16 in 2002) by searching areas where elk exhibited parturition behavior. We suggest that manufacturers refine the current VIT design to increase its application …


Causes Of Wolf Depredation Increase In Minnesota From 1979-1998, Elizabeth K. Harper, William J. Paul, L. David Mech Jan 2005

Causes Of Wolf Depredation Increase In Minnesota From 1979-1998, Elizabeth K. Harper, William J. Paul, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Wolf (Canis lupus) depredations on livestock in Minnesota have been increasing over the last 20 years. A major explanation cited for this increase is wolf range expansion, but no studies have tested this explanation. Additional reasons could include 1) wolf colonization of new areas within long-existing wolf range, 2) learning by wolves in established range, and 3) increased wolf density. We did not assess increasing wolf density as a factor because estimated wolf density in Minnesota has not increased. To assess how each of the other factors might have affected depredations, we created and analyzed a database of …

Weak Solutions To The Cauchy Problem Of A Semilinear Wave Equation With Damping And Source Terms, Petronela Radu Jan 2005

Weak Solutions To The Cauchy Problem Of A Semilinear Wave Equation With Damping And Source Terms, Petronela Radu

Department of Mathematics: Faculty Publications

In this paper we prove local existence of weak solutions for a semilinear wave equation with power-like source and dissipative terms on the entire space ℝn. The main theorem gives an alternative proof of the local in time existence result due to J. Serrin, G. Todorova and E. Vitillaro, and also some extension to their work. In particular, our method shows that sources that are not locally Lipschitz in L2 can be controlled without any damping at all. If the semilinearity involving the displacement has a “good” sign, we obtain global existence of solutions.


Review Of Tristan L’Hermite: Oeuvres Complètes. Iii: Poésie (Ii). Volume Publié Sous La Direction De Jean-Pierre Chauveau, Russell J. Ganim Jan 2005

Review Of Tristan L’Hermite: Oeuvres Complètes. Iii: Poésie (Ii). Volume Publié Sous La Direction De Jean-Pierre Chauveau, Russell J. Ganim

Department of Modern Languages and Literatures: Faculty Publications

This effort marks the second volume of poetry in a five-set edition of complete works consisting of Tristan’s prose, poetry and tragedies, as well as other plays and the Plaidoyers historiques. The present volume represents the culmination of an extensive undertaking by Champion and by noted Tristan scholars to render the Baroque author’s known works more accessible to researchers, students and the literate public. By any measure, the results are eminently satisfying both in terms of the volume in question and the entire project. This volume centres on texts composed and published mainly in the period afterwards. The principal …


Théâtre Et Théâtralité Chez Flaubert, Marshall C. Olds Jan 2005

Théâtre Et Théâtralité Chez Flaubert, Marshall C. Olds

French Language and Literature Papers

De tous les écrits dits secondaires de Gustave Flaubert, c'est incontestablement son théâtre qui a été le dernier à susciter un examen critique sérieux. Dans l'immense bibliographie consacrée au romancier et à son oeuvre, les études sur le théâtre ont, jusqu'à très récemment, occupé peu de place : quelques pages, lues ça et là dans les analyses des romans ou dans les biographies, un nombre infime d'articles consacrés aux caractéristiques théâtrales de l'oeuvre romanesque, la publication très irrégulière d'inédits de projets de théâtre ou de notes de lecture théâtrale dont les manuscrits font surface de temps en temps dans le …


Globalisation And 'La Pièce De Cent Sous': Balzac's Nation-State, Marshall C. Olds Jan 2005

Globalisation And 'La Pièce De Cent Sous': Balzac's Nation-State, Marshall C. Olds

French Language and Literature Papers

Seen from an Olympian perspective, globalisation in today's world denotes the use of a standard model to establish relationships economic, cultural, and moral—across peoples in the absence of national boundaries capable of restraining the formation of such ties. From the national, or local, perspective, it is the invasive imposition of foreign influence in the form of a single model. From either vantage point, change and adaptation are the order of the day. Take-overs of one culture by another, whether hostile or friendly, are not historical novelties; what seems to distinguish globalisation is its planetary scope and impetus to take over …


Chlorovirus: A Genus Of Phycodnaviridae That Infects Certain Chlorella-Like Green Algae, Ming Kang, David Dunigan, James L. Van Etten Jan 2005

Chlorovirus: A Genus Of Phycodnaviridae That Infects Certain Chlorella-Like Green Algae, Ming Kang, David Dunigan, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Taxonomy: Chlorella viruses are assigned to the family Phycodnaviridae, genus Chlorovirus, and are divided into three species: Chlorella NC64A viruses, Chlorella Pbi viruses and Hydra viridis Chlorella viruses. Chlorella viruses are large, icosahedral, plaque-forming, dsDNA viruses that infect certain unicellular, chlorella-like green algae. The type member is Paramecium bursaria chlorella virus 1 (PBCV-1).

Physical properties: Chlorella virus particles are large (molecular weight ~1 × 109 Da) and complex. The virion of PBCV-1 contains more than 100 different proteins; the major capsid protein, Vp54, comprises ~40% of the virus protein. Cryoelectron microscopy and three-dimensional image reconstruction of PBCV-1 virions …


Proline Suppresses Apoptosis In The Fungal Pathogen Colletotrichum Trifolii, Changbin Chen, Martin B. Dickman Jan 2005

Proline Suppresses Apoptosis In The Fungal Pathogen Colletotrichum Trifolii, Changbin Chen, Martin B. Dickman

Department of Plant Pathology: Faculty Publications

The role of reactive oxygen species (ROS) in cell communication, control of gene expression, and oxygen sensing is well established. Inappropriate regulation of ROS levels can damage cells, resulting in a diseased state. In Colletotrichum trifolii, a fungal pathogen of alfalfa, the mutationally activated oncogenic fungal Ras (DARas) elevates levels of ROS, causing abnormal fungal growth and development and eventual apoptotic-like cell death but only when grown under nutrient-limiting conditions. Remarkably, restoration to the wild-type phenotype requires only proline. Here, we describe a generally unrecognized function of proline: its ability to function as a potent antioxidant and inhibitor of …


The Interplay Of Traits And Motives On Volunteering: Agreeableness, Extraversion And Prosocial Value Motivation, Gustavo Carlo, Morris A. Okun, George Knight, Maria Rosario T. De Guzman Jan 2005

The Interplay Of Traits And Motives On Volunteering: Agreeableness, Extraversion And Prosocial Value Motivation, Gustavo Carlo, Morris A. Okun, George Knight, Maria Rosario T. De Guzman

Department of Psychology: Faculty Publications

Social psychology and personality theorists have proposed that our understanding of prosocial behavior will be enhanced by examining the interplay of traits and motives. The present study was designed to test several pathways by which agreeableness, extraversion, and prosocial value motivation to volunteer influence volunteerism. A sample of 796 college students completed measures of the Big Five traits, prosocial value motivation to volunteer, and volunteering. Results of path analyses showed that prosocial value motivation to volunteer partially mediated the relations between agreeableness and extraversion, and volunteering. Furthermore, as agreeableness decreased, extraversion was more strongly related to prosocial value motivation to …


Chlorella Virus Marburg Topoisomerase Ii: High Dna Cleavage Activity As A Characteristic Of Chlorella Virus Type Ii Enzymes, Jennifer S. Dickey, Tae-Jin Choi, James L. Van Etten, Neil Osheroff Jan 2005

Chlorella Virus Marburg Topoisomerase Ii: High Dna Cleavage Activity As A Characteristic Of Chlorella Virus Type Ii Enzymes, Jennifer S. Dickey, Tae-Jin Choi, James L. Van Etten, Neil Osheroff

Department of Plant Pathology: Faculty Publications

Although the formation of a covalent enzyme-cleaved DNA complex is a prerequisite for the essential functions of topoisomerase II, this reaction intermediate has the potential to destabilize the genome. Consequently, all known eukaryotic type II enzymes maintain this complex at a low steady-state level. Recently, however, a novel topoisomerase II was discovered in Paramecium bursaria chlorella virus-1 (PBCV-1) that has an exceptionally high DNA cleavage activity [Fortune et al. (2001) J. Biol. Chem. 276, 24401-24408]. If robust DNA cleavage is critical to the physiological functions of chlorella virus topoisomerase II, then this remarkable characteristic should be …


Role Of The Hypervariable Hinge Region Of Phosphoprotein P Of Vesicular Stomatitis Virus In Viral Rna Synthesis And Assembly Of Infectious Virus Particles, Subash C. Das, Asit K. Pattnaik Jan 2005

Role Of The Hypervariable Hinge Region Of Phosphoprotein P Of Vesicular Stomatitis Virus In Viral Rna Synthesis And Assembly Of Infectious Virus Particles, Subash C. Das, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The phosphoprotein (P protein) of vesicular stomatitis virus (VSV) is an essential subunit of the viral RNAdependent RNA polymerase and has multiple functions residing in its different domains. In the present study, we examined the role of the hypervariable hinge region of P protein in viral RNA synthesis and recovery of infectious VSV by using transposon-mediated insertion mutagenesis and deletion mutagenesis. We observed that insertions of 19-amino-acid linker sequences at various positions within this region affected replication and transcription functions of the P protein to various degrees. Interestingly, one insertion mutant was completely defective in both transcription and replication. Using …

Genome Of Deerpox Virus, C. L. Afonso, Gustavo A. Delhon, E. R. Tuhlman, Z. Lu, A. Zsak, V. M. Becerra, L. Zsak, G. F. Kutish, D. L. Rock

Nebraska Center for Virology: Faculty Publications

Deerpox virus (DPV), an uncharacterized and unclassified member of the Poxviridae, has been isolated from North American free-ranging mule deer (Odocoileus hemionus) exhibiting mucocutaneous disease. Here we report the genomic sequence and comparative analysis of two pathogenic DPV isolates, W-848-83 (W83) and W-1170-84 (W84). The W83 and W84 genomes are 166 and 170 kbp, containing 169 and 170 putative genes, respectively. Nucleotide identity between DPVs is 95% over the central 157 kbp. W83 and W84 share similar gene orders and code for similar replicative, structural, virulence, and host range functions. DPV open reading frames (ORFs) with putative …

Evolution Of Subtype C Hiv-1 Env In A Slowly Progressing Zambian Infant, Hong Zhang, Federico Hoffmann, Jun He, Xiang He, Chipepo Kankasa, Ruth Ruprecht, John T. West, Guillermo Orti, Charles Wood

Nebraska Center for Virology: Faculty Publications

Background: Given the high prevalence of mother to child infection, the development of a better understanding of African subtype C HIV-1 transmission and natural evolution is of significant importance. In this study, we genotypically and phenotypically characterized subtype C viruses isolated over a 67-month follow-up period from an in utero-infected Zambian infant. Changes in genotype and phenotype were correlated to alterations of the host humoral immune response.

Results: A comparison of baseline maternal and infant samples indicated that the infant sequences are monophyletic and contain a fraction of the diversity observed in the mother. This finding suggests that selective …

Epidemiological Characteristics Of Human Herpesvirus-8 Infection In A Large Population Of Antenatal Women In Zambia, W. Klaskala, B. P. Brayfield, C. Kankasa, G. Bhat, J. T. West, C. D. Mitchell, Charles Wood

Nebraska Center for Virology: Faculty Publications

Comprehensive data describing epidemiological characteristics of the human herpesvirus-8 or Kaposi’s sarcoma-associated herpesvirus (HHV-8 or KSHV) infection among pregnant women in a central sub-Saharan Africa are not available. This study determined virus prevalence estimates and the risk factors associated with HHV-8 infection. Cross-sectional, enrollment visit data were analyzed from a prospective cohort study of perinatal transmission of HHV-8 in Lusaka, Zambia. Exposure data were obtained via structured interview, physical examination, medical chart review, and laboratory testing. Among 3,160 antenatal women serologically screened for HHV-8 between September 1998 and October 2000, 40.2% were seropositive. The HHV-8 positive women were more likely …

Compartmentalization Of Hiv-1 In The Central Nervous System: Role Of The Choroid Plexus, Evan J. Burkala, Jun He, John T. West, Charles Wood, Carol K. Petito

Nebraska Center for Virology: Faculty Publications

Objectives: To determine the genetic and phenotypic composition of HIV-1 found in the choroid plexus (CPx) and its relationship to virus in the brain and peripheral lymphoid tissue. Design: Phenotypic and molecular comparisons of HIV-1 found in autopsy brain, CPx, and spleen tissues. Methods: HIV-1 was co-cultured from matched postmortem brain (basal ganglia), CPx, and spleen tissues of AIDS patients with and without HIV-associated encephalitis and dementia. Viral phenotypes were determined by infection of monocyte-derived macrophages, MT-2 or co-receptor-specific cell lines. Viral env and pol sequences were determined from genomic DNA isolated directly from tissues or co-cultures, and phylogenetic comparisons …


Dichotomy In Cross-Clade Reactivity And Neutralization By Hiv-1 Sera: Implications For Active And Passive Immunotherapy, Lisa A. Cavacini, Mark Duval, Ajay Patil, Charles Wood, Kanneth H. Mayer, Ruth M. Ruprecht, Marshall L. Posner Jan 2005

Dichotomy In Cross-Clade Reactivity And Neutralization By Hiv-1 Sera: Implications For Active And Passive Immunotherapy, Lisa A. Cavacini, Mark Duval, Ajay Patil, Charles Wood, Kanneth H. Mayer, Ruth M. Ruprecht, Marshall L. Posner

Nebraska Center for Virology: Faculty Publications

The identification of broadly reactive and cross-clade neutralizing antibodies will facilitate the development of a more universally effective vaccine for human immunodeficiency virus (HIV). Antibodies in sera from individuals infected with Clade B HIV bind native primary viral isolates, and virus binding correlates with neutralization and stable clinical disease. In this study, we quantified cross-clade antibody reactivity and neutralization by Clades B and C sera. Primary viral isolates were captured by serum IgG bound to anti-human IgG and quantitated as p24 released by lysis of captured virus. Neutralization was determined using PHA-stimulated PBMC. Clade B antibodies reacted more frequently with …


Cutting Edge: Cd4+Cd25+ Regulatory T Cells Contribute To Gender Differences In Susceptibility To Experimental Autoimmune Encephalomyelitis, Jay Reddy, Hanspeter Waldner, Xingmin Zhang, Zsolt Illes, Kai W. Wucherpfennig, Raymond A. Sobel, Vijay K. Kuchroo Jan 2005

Cutting Edge: Cd4+Cd25+ Regulatory T Cells Contribute To Gender Differences In Susceptibility To Experimental Autoimmune Encephalomyelitis, Jay Reddy, Hanspeter Waldner, Xingmin Zhang, Zsolt Illes, Kai W. Wucherpfennig, Raymond A. Sobel, Vijay K. Kuchroo

Jay Reddy Publications

Female B10.S mice are highly resistant to proteolipid protein (PLP) 139–151-induced experimental autoimmune encephalomyelitis (EAE) and depletion of PLP 139–151- reactive CD4+CD25+regulatory T (Treg) cells can slightly increase their EAE susceptibility. Although male B10.S mice are moderately susceptible to EAE, we report that depletion of Treg cells in male B10.S mice before immunization with PLP 139–151 renders them highly susceptible to severe EAE with more CNS neutrophil infiltrates than nondepleted controls. Increased susceptibility is associated with an enhanced PLP 139–151-specific T cell response and greater production of IFN-γ, IL-6, and IL-17. Male CD4+CD25+ effector cells depleted of Treg cells proliferate …


Latency-Related Gene Encoded By Bovine Herpesvirus 1 Promotes Virus Growth And Reactivation From Latency In Tonsils Of Infected Calves, Sandra Perez, Melissa Inman, Alan R. Doster, Clinton J. Jones Jan 2005

Latency-Related Gene Encoded By Bovine Herpesvirus 1 Promotes Virus Growth And Reactivation From Latency In Tonsils Of Infected Calves, Sandra Perez, Melissa Inman, Alan R. Doster, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Infection of calves with bovine herpesvirus 1 (BHV-1) results in transient immunosuppression that may lead to bacterium-induced pneumonia and, occasionally, death. Although sensory neurons in the trigeminal ganglia (TG) are the primary site of BHV-1 latency, viral genomes are detected in the tonsils of latently infected calves. Dexamethasone (DEX) consistently induces reactivation from latency, and viral gene expression is detected in TG and tonsils. In sensory neurons of latently infected calves, the latency-related (LR) gene is abundantly expressed and is required for reactivation from latency. In the present study, we compared the abilities of wild-type (wt) BHV-1 and a strain …
