Dynamics Of The Arctic Fox Population On St. Lawrence Island, Bering Sea, Francis H. Fay, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

English abstract: We hypothesized that the arctic fox, Alopex lagopus (Linnaeus), population on St. Lawrence Island was cyclic and that its fluctuations in size. structure, and productivity were correlated with the relative size of the population of northern voles, Microtus oeconomus Pallas, the primary prey. Based on a nine-year study, we determined that the variations in size of the fox and vole populations were similar, but they both were of low amplitude and not closely correlated. The high pregnancy rate (mean, 86%/yr) and numbers of young conceived (mean, 11.5/pregnancy) did not vary significantly among years, probably because of the consistently …

Sighting Of A Canyon Wren In Knox County, Nebraska, Mark A. Brogie

Nebraska Bird Review

The Canyon Wren (Catherpes mexicanus) is found in all states west of the Rocky Mountains; however, east of the Rockies it resides only in western Oklahoma, and in western and central Texas, with a separate population in the Black Hills of Wyoming and South Dakota. It has never been recorded in North Dakota or Kansas, or in any state whose entire boundaries lie east of the 100^th meridian (DeSante and Pyle 1986). This species is almost entirely resident over its range, although a few most northerly populations depart in winter, and there are some altitudinal migrations to …

Inventory Of Rare Plant Species In The Pine Ridge Area Of Nebraska (Dawes And Sioux County, Nebraska), Michael I. Fritz, Joyce Philips Hardy, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The purpose of this project was to conduct a systematic inventory of rare plant species on the Pine Ridge District of the Nebraska National Forest. The objective of the inventory was to locate rare plant occurrences and compile information on their location, status and any possible threats. Four areas within the Pine Ridge District were identified as priority areas for the inventory fieldwork. The four tracts included the Soldier Creek Wilderness Area, a tract encompassing the East and West Ash Creek drainages, a middle unit tract, and a tract which straddles U.S. Highway 385 and encompasses a number of timber …

The Entner-Doudoroff Pathway In Escherichia Coli Is Induced For Oxidative Glucose Metabolism Via Pyrroloquinoline Quinone-Dependent Glucose Dehydrogenase, Ronda Fliege, Suxiang Tong, Annemarie Shibata, Kenneth W. Nickerson, Tyrrell Conway

Papers in Microbiology

The Entner-Doudoroff pathway was shown to be induced for oxidative glucose metabolism when Escherichia coli was provided with the periplasmic glucose dehydrogenase cofactor pyrroloquinoline quinone (PQQ). Induction of the Entner-Doudoroff pathway by glucose plus PQQ was established both genetically and biochemically and was shown to occur in glucose transport mutants, as well as in wild-type E. coli. These data complete the body of evidence that proves the existence of a pathway for oxidative glucose metabolism in E. coli. PQQ-dependent oxidative glucose metabolism provides a metabolic branch point in the periplasm; the choices are either oxidation to gluconate followed …

Processing And Localization Of Dengue Virus Type 2 Polyprotein Precursor Ns3-Ns4a-Ns4b-Ns5, Luwen Zhang, P. Maruthi Mohan, R. Padmanabhan

Nebraska Center for Virology: Faculty Publications

Processing of dengue virus type 2 polyprotein precursor NS3-NS4A-NS4B-NS5 could be mediated by the catalytically active NS3 protease domain and NS2B in trans at the dibasic sites NS3-NS4A and NS4B-NS5. Subcellular localization of the unprocessed precursor NS3-NS4A-NS4B-NS5 showed that it was confined to a distinct subcellular organelle in the cytoplasm, which was distinct from the distribution of the mature NS5.

Loss Of Infectivity By Progeny Virus From Alpha Interferon- Treated Human Immunodeficiency Virus Type 1-Infected T Cells Is Associated With Defective Assembly Of Envelope Gp120, Brian D. Hanson, Peter L. Nara, Radha K. Maheshwari, Girmel S. Sidhu, John G. Bernbaum, David Hoekzema, Monte S. Meltzer, Howard Gendelman

Nebraska Center for Virology: Faculty Publications

Levels of human immunodeficiency virus (HIV) DNA, RNA, or p24 antigen and reverse transcriptase activity in T-cell cultures treated with 500 IU of recombinant alpha interferon (rIFNα) per ml were comparable to those in control cultures. Radioimmunoprecipitation analysis of proteins in lysates of IFN-treated T cells documented a marked accumulation of HlV proteins. Localization of gp120 by immunofluorescence showed a diffuse pattern in IFN-treated cells quite distinct from the ring pattern in untreated control cells. That large quantities of a120 in aberrant cell compartments might affect HlV morphogenesis was confirmed in infectivity studies: virions from IFN-treated cells were 100- to …

He became a member of the faculty of UNC in Greeley In 1966. His collaboration …

Simulating Winter Wheat Shoot Apex Phenology , G. S. Mcmaster, Wallace Wilhelm, J. A. Morgan

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

Simulation models are heuristic tools for integrating diverse processes and help to increase our understanding of complex processes and systems. Models that predict crop development can serve as decision-support tools in crop management. This paper describes a phenology simulation model for the winter wheat shoot apex and reports validation and sensitivity analysis results.

The complete developmental sequence of the winter wheat shoot apex is quantitatively outlined and correlated with commonly recognized phenological growth stages. The phyllochron is used to measure the thermal time between most phenological growth stages, thereby increasing the flexibility over the growing degree-day (GDD) and photothermal approaches. …

Low Pressure Center Pivot And Soil Management Effects On Runoff, L. N. Mielke, J. R. Gilley, Wallace Wilhelm

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

The objective of this research was to determine the influence center-pivot sprinkler irrigation methods in combination with tillage practices for corn (Zea mays L.) have on surface runoff of irrigation and rainfall. A center pivot irrigation machine was redesigned to apply water by high-pressure-impact (HPI), low-pressure-impact (LPI), and low-pressure-spray (LPS) nozzles. The center-pivot was a standard 10-tower machine, 395 meters in length and 38.4 meters tower spacing. Three tillage systems were used -- till-plant (T), disk (D), and subtill (S) which was till-plant with subsoiling between rows with straight single shanks, 360 mm deep, after last cultivation. The soil …

Simulating Winter Wheat Spike Development And Growth, Gregory S. Mcmaster, Jack A. Morgan, Wallace Wilhelm

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

Mechanistic crop simulation models can aid in integrating and directing research, and in improving farm management strategies. Information derived from recent research on spike development and growth of winter wheat (Triticum aestivum L.) was incorporated into a submodel, SPIKEGRO, and added to an existing model called SHOOTGRO. This manuscript discusses the SPIKEGRO submodel.

SPIKEGRO emphasizes the reproductive functioning of the shoot apex. The complete developmental sequence of the shoot apex is outlined and quantified. All developmental events and growth stages are predicted, most using the phyllochron approach. Spikelet and floret primordium initiation, growth, and abortion; ovule fertilization and growth; …

Parasites Of The Extinct Shasta Ground Sloth, Nothrotheriops Shastensis, In Rampart Cave, Arizona, Gerald D. Schmidt, Donald W. Duszynski, Paul S. Martin

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Of 7 dissected dung balls of the extinct Shasta ground sloth (Edentata) from Rampart Cave, Arizona, 4 (57%) were found to contain nematode juveniles, helminth eggs, and/or coccidian oocysts. One dung ball was radiocarbon dated at 10,500 ± 180 yr, about the time of ground sloth extinction. It is supposed that the parasites also are extinct. Agamofilaria oxyura n. sp. is proposed for first-stage juveniles of an oxyurid. These juveniles measured 13-20 x 126-198 (16.8 x 159) μm. Strongyloides shastensis n. sp. is reported as first-stage juveniles, some of which clearly are molting. These juvenile worms were 23-27 …

Resource Tracking In North American Telorchis Spp. (Digenea: Plagiorchiformes: Telorchidae), Alison Radtke, Deborah A. Mclennan, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

We examine the evolution of host specificity for species of Telorchis, using the methods developed by researchers studying phytophagous insect-plant systems. Optimization of "generalist" compared with "specialist" onto the phylogeny for Telorchis revealed ambiguous patterns, depending on how the two terms were defined. Regardless of that definition, most of the evolutionary diversification of this group has been carried out within eucryptodiran turtles, the ancestral host group. From that plesiomorphic background, there appears to have been two episodes of specialization by way of a host switch into caudates (ancestor of T. stunkardi + T. sirenis) and snakes (T. …

New Distribution Records For Bunodera Eucaliae And Bunodera Inconstans N. Comb. (Digenea: Allocreadiidae: Bunoderinae) With Discussion Of Their Phylogenetic Relationships, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Bunodera eucaliae inhabits Culaea inconstans from eastern Ontario and western Nebraska, both new geographic distribution records. Culaeatrema inconstans inhabits Culaea inconstans from eastern Ontario, also a new distribution record. Comparison of Culaeatrema inconstans with species of Paracreptotrematina, Bunoderella, Bunodera, and Crepidostomum within a phylogenetic context suggests that it is the sister species of B. eucaliae. Accordingly, it is transferred to Bunodera, although the monophyly of Bunodera as a group has not yet been established because there is no synapomorphy linking Bunodera luciopercae with the clade containing Bunodera mediovitellata, Bunodera sacculata, B. eucaliae, …

Collapse Of The Proton Motive Force In Listeria Monocytogenes Caused By A Bacteriocin Produced By Pediococcus Acidilactici, Douglas P. Christensen, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

The effect of pediocin JD, a bacteriocin produced by Pediococcus acidilactici JD1-23, on the proton motive force and proton permeability of resting whole cells of Listeria monocytogenes Scott A was determined. Control cells, treated with trypsin-inactivated bacteriocin at a pH of 5.3 to 6.1, maintained a pH gradient and a membrane potential of approximately 0.65 pH unit and 75 mV, respectively. However, these gradients were rapidly dissipated in cells after exposure to pediocin JD, even though no cell lysis had occurred. The pH gradient and membrane potential of the producer cells were also unaffected by the bacteriocin. Whole cells treated …

A New Species Of Linstowia (Cestoda: Anoplocephalidae) From Marsupials In Bolivia, Scott Lyell Gardner, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

A new species of cestode of the genus Linstowia (Cestoda: Anoplocephalidae) is described from marsupials of the genera Thylamys and Monodelphis. The new species (Linstowia schmidti) differs from Linstowia iheringi Zschokke, 1904, in having a much smaller strobila and reduced number of proglottids, and in the distribution of the eggs in gravid proglottids. In Bolivia, cestodes of the genus Linstowia appear to have a restricted geographic distribution, occurring in marsupials only in southeastern Bolivia near the western margin of the Chaco. This host-parasite association may represent an ecological-historical relict.

Critical Comment: Designation And Curatorial Management Of Type Host Specimens (Symbiotypes) For New Parasite Species, Jennifer K. Frey, Terry L. Yates, Donald Duszynski, William L. Gannon, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The accurate identification of a host organism is an important component in the taxonomic recognition of a new species of parasite. Correct identification, curatorial management, and safekeeping of the host specimen from which a parasite type specimen is collected is also desirable. We recommend that the host from which the type of a new parasite species is described should be designated as a symbiotype.
