Unearthing Archaeology: A Study Of The Recent Coverage Of Selected English-Language Archaeology Journals By Multi-Subject Indexes And By Anthropological Literature, David C. Tyler, Yang Xu, Emily Dust Nimsakont Jan 2009

Unearthing Archaeology: A Study Of The Recent Coverage Of Selected English-Language Archaeology Journals By Multi-Subject Indexes And By Anthropological Literature, David C. Tyler, Yang Xu, Emily Dust Nimsakont

University of Nebraska-Lincoln Libraries: Faculty Publications

Librarians, faculty, and professional researchers, and students already encounter difficulties in locating journal articles for the field of archaeology, yet, in the current budgetary climate, librarians needing to reduce subscription costs may be tempted to cancel smaller, discipline-specific indexes in favor of large multi- subject indexes with broad coverage. This study examines and compares the coverage provided to 208 archaeology and archaeology-related journals and magazines by six multi-subject indexes (Academic Search Premier, ArticleFirst, eLibrary, IngentaConnect, Wilson OmniFile, Web of Science) and by anthropology’s primary index, Anthropological Literature, over a twenty year period (1988–2007).

Creating Online Tutorials At Your Libraries: Software Choices And Practical Implications, Maribeth Slebodnik, Catherine Fraser Riehle Jan 2009

Creating Online Tutorials At Your Libraries: Software Choices And Practical Implications, Maribeth Slebodnik, Catherine Fraser Riehle

University of Nebraska-Lincoln Libraries: Faculty Publications

The use of online tutorials for information literacy instruction is on the rise. Active library-related discussion lists such as ILI-L, the Association of College and Research Libraries’ discussion on information literacy and instruction, and LIBREF-L typically feature several questions and surveys related to online tutorials every week. Discussion groups and forums at library conferences consistently offer discussions, programs, and resources about creating online tutorials, and share examples. What is causing the surge of interest in online tutorials? Reasons vary: staff shortages, a desire to provide more point-of-need assistance, and increased distance learning and a growing awareness—particularly in public and academic …

Elementary Teachers’ Conceptions Of Flooding Before And After Professional Development, Elizabeth B. Lewis, Katrien J. Kraft, Nievita Bueno Watts, Meredith J. Wilson, Dale R. Baker, Michael Lang Jan 2009

Elementary Teachers’ Conceptions Of Flooding Before And After Professional Development, Elizabeth B. Lewis, Katrien J. Kraft, Nievita Bueno Watts, Meredith J. Wilson, Dale R. Baker, Michael Lang

Department of Teaching, Learning, and Teacher Education: Presentations

This study focuses on elementary teachers' conceptions of flooding before and after inquiry-based Earth science content-based professional development. Several misconceptions emerged from the science content two tier pre-post test, some of which persisted throughout the institute while others led to evidence of teachers' conceptual change. On the post-test some teachers' ideas emerged as hybrid conceptions as they applied newly acquired academic language to prior conceptions. There was a significant increase (n = 17, mean gain = 4.3 (SD = 3.27, t (17) = 5.69, p < .000) from the pre- to post-test. The concepts most resistant to change from pre- to post-test were analyzing an overall topographic region, reading a map image, and hydrograph interpretation. The highest frequency of hybrid conceptions occurred as teachers attempted to add new academic language, such as storm surge and discharge, to their prior understandings. Teachers’ greatest conceptual change occurred in understanding the probability and role of ground conditions in flooding events. Teachers demonstrated significant growth in their understanding of flooding concepts through scaffolded inquiry lessons modeled through the professional development. Teachers who had greater levels of prior knowledge showed the most change to a normative view of flooding. This speaks to the importance of building teachers' background knowledge before initiating professional development with complex science concepts.

Spatial Ecology Of Raccoons Related To Cattle And Bovine Tuberculosis In Northeastern Michigan, Todd Atwood, Thomas Deliberto, Holly Smith, Justin Stevenson, Kurt C. Vercauteren Jan 2009

Spatial Ecology Of Raccoons Related To Cattle And Bovine Tuberculosis In Northeastern Michigan, Todd Atwood, Thomas Deliberto, Holly Smith, Justin Stevenson, Kurt C. Vercauteren

Michigan Bovine Tuberculosis Bibliography and Database

In 1995, Mycobacterium bovis, the causative bacterium of bovine tuberculosis (bTB), was detected in 5 beef cattle operations in Alcona County, Michigan, USA. In accordance with Federal law, the operations were depopulated to prevent the spread of bTB. Subsequent wildlife surveillance programs identified high prevalence of M. bovis in mesocarnivores, including raccoons ( Procyon lotor), which suggested that raccoons may be complicit in vectoring the pathogen among livestock operations. Our goal was to develop an empirical basis for generating hypotheses about the likelihood for raccoons to mediate the transmission of bTB to livestock. We found intersexual differences in …

1. Understanding the effects of disease is critical to determining appropriate management responses, but estimating those effects in wildlife species is challenging. We used bovine tuberculosis (BTB) in the African buffalo Syncerus caffer population of Kruger National Park, South Africa, as a case study to highlight the issues associated with estimating chronic disease effects in a long-lived host.

2. We used known and radio-collared buffalo, aerial census data, and a natural gradient in pathogen prevalence to investigate if: (i) at the individual level, BTB infection reduces reproduction; (ii) BTB infection increases vulnerability to predation; and (iii) at the population level, …

Evaluation Of Blood Assays For Detection Of Mycobacterium Bovis In White-Tailed Deer (Odocoileus Virginianus) In Michigan, Daniel J. O’Brien, Stephen M. Schmitt, Konstantin P. Lyashchenko, W. Ray Waters, Dale E. Berry, Mitchell V. Palmer, Jim Mcnair, Rena Greenwald, Javan Esfandiari, Melinda K. Cosgrove

Michigan Bovine Tuberculosis Bibliography and Database

Surveillance and control activities related to bovine tuberculosis (TB) in free-ranging, Michigan white-tailed deer (Odocoileus virginianus) have been underway for over a decade, with significant progress. However, foci of higher TB prevalence on private lands and limited agency ability to eliminate them using broad control strategies have led to development and trial of new control strategies, such as live trapping, testing, and culling or release. Such strategies require a prompt, accurate live animal test, which has thus far been lacking. We report here the ability of seven candidate blood assays to determine the TB infection status of Michigan …

Tuberculosis: A Re-Emerging Disease In Animals And Humans, Charles O. Thoen, Philip A. Lobue, Donald A. Enarson, John B. Kaneene, Isabel N. De Kantor Jan 2009

Tuberculosis: A Re-Emerging Disease In Animals And Humans, Charles O. Thoen, Philip A. Lobue, Donald A. Enarson, John B. Kaneene, Isabel N. De Kantor

Michigan Bovine Tuberculosis Bibliography and Database

Tuberculosis continues to be an important disease both in humans and animals. It causes morbidity, mortality, and economic loss worldwide. The occurrence of Mycobacterium bovis disease in humans, domesticated and wild animals confirms the relevance of this zoonosis. M. bovis in humans continues to be reported in industrialized countries and in immigrants from regions of the world where tuberculosis in cattle is endemic. The real incidence of M. bovis in humans in developing countries continues to be roughly underestimated due to the scarcity of appropriate laboratory facilities to isolate and to differentiate M. bovis strains. In Latin America, less than …

A New Filatima Busck (Lepidoptera: Gelechiidae) Associated With Lupine And Early Herbivore Colonization On Mount St. Helens, David Adamski, Jennifer L. Apple, John G. Bishop

USDA Systematic Entomology Laboratory

Filatima loowita, n. sp. is described from the Pumice Plain on Mount St. Helens in Washington, United States. An apparent specialist on lupine, early instars feed as leaf-miners, while later instars tie leaflets together into silken tunnels and feed externally, mainly on the leaf tissue. The larvae make webbed tunnels, which extend from the root bundles to the uppermost leaves of the plant. Illustrations are provided of the adult male and female genitalia, and chaetotaxal maps of the last-instar larva, supplemented with scanning electron micrographs and images of the host on the volcano.

A New Holcocera Clemens From Guatemala And Redescription Of H. Iceryaeella (Riley) From The United States (Lepidoptera: Coleophoridae: Blastobasinae: Holcocerini): Two Congeners With Incidental Preference For Avocado, David Adamski, Mark Hoddle

USDA Systematic Entomology Laboratory

Two species of Holcocera Clemens (Lepidoptera: Coleophoridae: Blastobasinae: Holcocerini) are known to feed on Persea americana Mill. (Lauraceae), but their frequency of infestation appears low. One species, Holcocera plagatola, n. sp., from Guatemala, is described herein. Holcocera iceryaeella (Riley) is known only from California and has been recorded on many different host plants; it is also known to be a predator of immature Hemiptera and scale insects. Photographs of the imagos of both Holcocera species are included, in addition to illustrations of the male and female genitalia. We comment on host preferences for both species.

Not All Oak Gall Wasps Gall Oaks: The Description Of Dryocosmus Rileypokei, A New, Apostate Species Of Cynipini From California, Matthew L. Buffington, Shelah I. Morita Jan 2009

Not All Oak Gall Wasps Gall Oaks: The Description Of Dryocosmus Rileypokei, A New, Apostate Species Of Cynipini From California, Matthew L. Buffington, Shelah I. Morita

USDA Systematic Entomology Laboratory

Cynipini gall wasps (Hymenoptera: Cynipidae) are commonly known as oak gall wasps for their almost exclusive use of oak (Quercus spp.; Fagaceae) as their host plant. Previously, only three of the nearly 1,000 species of Cynipini have been recorded from hosts other than Quercus. These three are known from western chinquapin (Chrysolepis), chestnut (Castanea) and tan bark oak (Lithocarpus), all lineages of Fagaceae related to Quercus. Here we describe Dryocosmus rileypokei Morita & Buffington, new species, a second species of cynipine which attacks Chrysolepis. Unlike the previously known gall wasp …

Description, Circumscription And Phylogenetics Of The New Tribe Zaeucoilini (Hymenoptera: Figitidae: Eucoilinae), Including A Description Of A New Genus, Matthew L. Buffington

USDA Systematic Entomology Laboratory

Neotropical eucoiline genera that have been included in and allied with the Zaeucoila genus group are redescribed. Following character analysis and phylogenetic reconstruction (25 taxa, 96 morphological characters, 1452 ribosomal and mitochondrial characters), this informal genus group was found to be monophyletic, and hence raised to formal recognition as a tribe of eucoilines, namely Zaeucoilini new tribe. Through phylogenetic reconstruction, Aegeseucoela Buffington was determined to be polyphyletic; the type species of Aegeseucoela, A. grenadensis (Ashmead), is transferred to Agrostocynips comb.n.; the orphaned species, A. flavotincta (Kieffer), is transferred to Marthiella Buffington gen.n., comb.n.

Killdeer Charadrius Vociferus Breeding Abundance And Habitat Use In The Eastern Rainwater Basin, Nebraska, Joel G. Jorgensen, John P. Mccarty, Lareesa Wolfenbarger Jan 2009

Killdeer Charadrius Vociferus Breeding Abundance And Habitat Use In The Eastern Rainwater Basin, Nebraska, Joel G. Jorgensen, John P. Mccarty, Lareesa Wolfenbarger

Nebraska Game and Parks Commission: Staff Research Publications

The Killdeer Charadrius vociferous is a common shorebird that breeds throughout much of North America. The most recent estimate of the total population of Killdeer is 1 million individuals, but this estimate is supported by few quantitative studies. We used distance sampling to survey Killdeer in the agricultural ecosystem of the Eastern Rainwater Basin, Nebraska. Our results show that as many as 100,000 Killdeer may breed in the Eastern Rainwater Basin. The region we surveyed covers a very small portion of the Killdeer’s overall breeding range, suggesting that the Killdeer population is likely >1 million birds. We also evaluated habitat …

Missouri River Fish And Wildlife Mitigation Program Fish Community Monitoring And Habitat Assessment Of Off-Channel Mitigation Sites, Van Sterner, Royce Bowman, Brandon Eder, Sabrina Negus, Gerald Mestl, Kasey Whiteman, Darrick Garner, Vince Travnichek, Joshua Schloesser, Joseph Mcmullen, Tracy Hill

Nebraska Game and Parks Commission: Staff Research Publications

The Missouri River has been developed for flood control, commercial navigation, irrigation, fish and wildlife conservation, municipal water supply, water quality control and hydropower production through a series of congressional acts. However, prior to development, the lower Missouri River was characterized by a highly sinuous to braided channel with abundant log jams, sand bars, secondary channels and cut-off channels. Construction of the Bank Stabilization and Navigation Project (BSNP) converted the lower Missouri River into a narrow, self scouring channel. The active channel downstream of Sioux City, Iowa was as wide as 1.8 km before river modification, but is now confined …

Genetic And Evolutionary Considerations In Fishery Management: Research Needs For The Future, Robin Waples, Kerry A. Naish Jan 2009

Genetic And Evolutionary Considerations In Fishery Management: Research Needs For The Future, Robin Waples, Kerry A. Naish

United States Department of Commerce: Staff Publications

Genetic methods have become indispensable for sound fishery management and will become even more so in the twenty-first century. Selectively neutral genetic markers are widely used in stock identification, mixed-stock fishery analysis, monitoring levels of genetic diversity within populations and levels of connectivity among populations, and for a range of other applications. We expect that future research will continue to provide incremental improvements in the number and type of genetic markers available, as well as in the methods for data analysis and the necessary computational resources. Topics that will merit special consideration include: (1) developing a better understanding of the …

Accounting For Uncertainty In Ecological Analysis: The Strengths And Limitations Of Hierarchical Statistical Modeling, Noel Cressie, Catherine A. Calder, James S. Clark, Jay M. Ver Hoef, Christopher K. Wikle Jan 2009

Accounting For Uncertainty In Ecological Analysis: The Strengths And Limitations Of Hierarchical Statistical Modeling, Noel Cressie, Catherine A. Calder, James S. Clark, Jay M. Ver Hoef, Christopher K. Wikle

United States Department of Commerce: Staff Publications

Analyses of ecological data should account for the uncertainty in the process(es) that generated the data. However, accounting for these uncertainties is a difficult task, since ecology is known for its complexity. Measurement and/or process errors are often the only sources of uncertainty modeled when addressing complex ecological problems, yet analyses should also account for uncertainty in sampling design, in model specification, in parameters governing the specified model, and in initial and boundary conditions. Only then can we be confident in the scientific inferences and forecasts made from an analysis. Probability and statistics provide a framework that accounts for multiple …

United States Army: Publications

Viruses-like particles (VLPs) are frequently being used as platforms for polyvalent display of foreign epitopes of interest on their capsid surface to improve their presentation enhancing the antigenicity and host immune response. In the present study, we used the VLPs of Tomato bushy stunt virus (TBSV), an icosahedral plant virus, as a platform to display 180 copies of 16 amino acid epitopes of ricin toxin fused to the C-terminal end of a modified TBSV capsid protein (NΔ52). Expression of the chimeric recombinant protein in insect cells resulted in spontaneous assembly of VLPs displaying the ricin epitope. Cryo-electron microscopy and image …
