Antibody Responses To Lytic And Latent Human Herpesvirus 8 Antigens Among Hiv-Infected Patients In Central China, Tiejun Zhang, Na He, Yingying Ding, Qingwu Jiang, Charles Wood

Nebraska Center for Virology: Faculty Publications

Human herpesvirus 8 (HHV8) is an important opportunistic infection of HIV/AIDS. However, very little is known about antibody seropositivities to HHV8 lytic and latent antigens among HIVinfected patients in China. Therefore, a cross-sectional study was conducted to explore HHV8 serostatus among 316 HIV-infected patients in a rural area of central China. The antibody seropositivity to HHV8 ORF65 (lytic) and LANA (latent) antigens was 12.7% and 10.4%, respectively. Patients who were naïve to antiretroviral therapy (ART) were more likely to be seropositive for antibodies to ORF65 (OR: 3.79; 95% CI: 1.71–8.42) and LANA (OR: 3.77; 95% CI: 1.55–9.14) than patients receiving …

Heme Oxygenase-1 Regulates The Immune Response To Influenza Virus Infection And Vaccination In Aged Mice, Nathan W. Cummins, Eric A. Weaver, Shannon M. May, Anthony J. Croatt, Oded Foreman, Richard B. Kennedy, Gregory A. Polan, Michael A. Barry, Karl A. Nath, Andrew D. Badley

Nebraska Center for Virology: Faculty Publications

Underlying mechanisms of individual variation in severity of influenza infection and response to vaccination are poorly understood. We investigated the effect of reduced heme oxygenase-1 (HO-1) expression on vaccine response and outcome of influenza infection. HO-1-deficient and wild-type (WT) mice (kingdom, Animalia; phylum, Chordata; genus/species, Mus musculus) were infected with influenza virus A/PR/8/34 with or without prior vaccination with an adenoviral-based influenza vaccine. A genome-wide association study evaluated the expression of single-nucleotide polymorphisms (SNPs) in the HO-1 gene and the response to influenza vaccination in healthy humans. HO-1-deficient mice had decreased survival after influenza infection compared to WT mice (median …

Utility Of Remotely Sensed Imagery For Assessing The Impact Of Salvage Logging After Forest Fires, Sarah A. Lewis, Pete Robichaud, Andrew T. Hudak, Brian Austin, Robert J. Liebermann

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Remotely sensed imagery provides a useful tool for land managers to assess the extent and severity of post-wildfire salvage logging disturbance. This investigation uses high resolution QuickBird and National Agricultural Imagery Program (NAIP) imagery to map soil exposure after ground-based salvage operations. Three wildfires with varying post-fire salvage activities and variable ground truth data were used to evaluate the utility of remotely sensed imagery for disturbance classification. The Red Eagle Fire in northwestern Montana had intensive ground truthing with GPS-equipment logging equipment to map their travel paths, the Tripod Fire in north central Washington had ground truthed disturbance transects, and …

Lake Sturgeon Population Attributes And Reproductive Structure In The Namakan Reservoir, Minnesota And Ontario, S. L. Shaw, S. R. Chipps, Steve K. Windels, M. A. H. Webb, Darryl T. Mcleod, D. W. Willis

United States Geological Survey: Staff Publications

Quantified were the age, growth, mortality and reproductive structure of lake sturgeon (Acipenser fulvescens) collected in the US and Canadian waters of the Namakan Reservoir. The hypotheses were tested that (i) age and growth of lake sturgeon in the Namakan Reservoir would differ by sex and reproductive stage of maturity, and (ii) that the relative strength of year classes of lake sturgeon in the reservoir would be affected by environmental variables. To quantify age, growth and mortality of the population, existing data was used from a multiagency database containing information on all lake sturgeon sampled in the reservoir …

The Driving Forces Of Land Change In The Northern Piedmont Of The United States, Roger F. Auch, Darrell E. Napton, Steven Kambly, Thomas R. Moreland Jr., Kristi L. Sayler

United States Geological Survey: Staff Publications

Driving forces facilitate or inhibit land-use / land-cover change. Human driving forces include political, economic, cultural, and social attributes that often change across time and space. Remotely sensed imagery provides regional land-change data for the Northern Piedmont, an ecoregion of the United States that continued to urbanize after 1970 through conversion of agricultural and forest land covers to developed uses. Eight major driving forces facilitated most of the land conversion; other drivers inhibited or slowed change. A synergistic web of drivers may be more important in understanding land change than individual drivers by themselves.

On Modeling Weak Sinks In Modpath, Daniel Abrams, H. Haitjema, L. Kauffman

United States Geological Survey: Staff Publications

Regional groundwater flow systems often contain both strong sinks and weak sinks. A strong sink extracts water from the entire aquifer depth, while a weak sink lets some water pass underneath or over the actual sink. The numerical groundwater flow model MODFLOW may allow a sink cell to act as a strong or weak sink, hence extracting all water that enters the cell or allowing some of that water to pass. A physical strong sink can be modeled by either a strong sink cell or a weak sink cell, with the latter generally occurring in low-resolution models. Likewise, a physical …

Association Between The Serotonin Transporter Triallelic Genotype And Eating Problems Is Moderated By The Experience Of Childhood Trauma In Women, Scott F. Stoltenberg, Cynthia Anderson, Parthasarathi Nag, Cheryl Anagnopoulos

Department of Psychology: Faculty Publications

Objective—This study investigated a potential interaction between the triallelic polymorphism of the serotonin transporter gene (SLC6A4) promoter and the experience of childhood trauma on the number of problem eating behaviors.

Methods—The study sample was comprised of 439 (64.7% female) Caucasian college students (mean age = 22.49, SD = 6.12). Participants completed questionnaires that assessed eating problems and experience of trauma in childhood (ages 0-12) and donated cheek cells for 5- HTTLPR and rs25531 genotyping.

Results—Women carrying a lower expressing allele (i.e. LG or S) who were exposed to higher levels of childhood trauma reported significantly higher mean numbers of eating …

Grizzly Bear Population Vital Rates And Trend In The Northern Continental Divide Ecosystem, Montana, Richard D. Mace, Daniel W. Carney, Tonya Chilton-Radandt, Stacy A. Courville, Mark A. Haroldson, Richard B. Harris, James Jonkel, Bruce Mclellan, Michael Madel, Timothy Manley, Charles Schwartz, Christopher Servheen, Gordon Stenhouse, John S. Waller, Erik Wenum

United States Geological Survey: Staff Publications

We estimated grizzly bear (Ursus arctos) population vital rates and trend for the Northern Continental Divide Ecosystem (NCDE), Montana, between 2004 and 2009 by following radio-collared females and observing their fate and reproductive performance. Our estimates of dependent cub and yearling survival were 0.612 (95% CI = 0.300–0.818) and 0.682 (95% CI = 0.258–0.898). Our estimates of subadult and adult female survival were 0.852 (95% CI = 0.628–0.951) and 0.952 (95% CI = 0.892– 0.980). From visual observations, we estimated a mean litter size of 2.00 cubs/litter. Accounting for cub mortality prior to the first observations of litters …

Use Of Real-Time Pcr To Detect Canine Parvovirus In Feces Of Free-Ranging Wolves, L. David Mech, Emily S. Almberg, Douglas Smith, Sagar Goyal, Randall S. Singer

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

Using real-time PCR, we tested 15 wolf (Canis lupus) feces from the Superior National Forest (SNF), Minnesota, USA, and 191 from Yellowstone National Park (YNP), USA, collected during summer and 13 during winter for canine parvovirus (CPV)-2 DNA. We also tested 20 dog feces for CPV-2 DNA. The PCR assay was 100%sensitive and specific with a minimum detection threshold of 104 50% tissue culture infective dose. Virus was detected in two winter specimens but none of the summer specimens. We suggest applying the technique more broadly especially with winter feces.

Nest Defense- Grassland Bird Responses To Snakes, Kevin Ellison, Christine Ribic

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

Predation is the primary source of nest mortality for most passerines; thus, behaviors to reduce the impacts of predation are frequently quantified to study learning, adaptation, and coevolution among predator and prey species. Video surveillance of nests has made it possible to examine real-time parental nest defense. During 1999-2009, we used video camera systems to monitor 518 nests of grassland birds. We reviewed video of 48 visits by snakes to 34 nests; 37 of these visits resulted in predation of active nests. When adult birds encountered snakes at the nest (n = 33 visits), 76% of the encounters resulted …

Quantifying Aboveground Forest Carbon Pools And Fluxes From Repeat Lidar Surveys, Andrew T. Hudak, Eva K. Strand, Lee A. Vierling, John C. Byrne, Jan U. H. Eitel, Sebastián Martinuzzi, Michael J. Falkowski

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Sound forest policy and management decisions to mitigate rising atmospheric CO₂ depend upon accurate methodologies to quantify forest carbon pools and fluxes over large tracts of land. LiDAR remote sensing is a rapidly evolving technology for quantifying aboveground biomass and thereby carbon pools; however, little work has evaluated the efficacy of repeat LiDAR measures for spatially monitoring aboveground carbon pools through time. Our study objective was therefore to evaluate the use of discrete return airborne LiDAR for quantifying biomass change and carbon flux from repeat field and LiDAR surveys. We collected LiDAR data in 2003 and 2009 across ~20,000 …

Development Of Camera Technology For Monitoring Nests, W. Andrew Cox, M. Shane Pruett, Thomas J. Benson, Scott J. Chiavacci, Frank R. Thompson Iii

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

Photo and video technology has become increasingly useful in the study of avian nesting ecology. However, researchers interested in using camera systems are often faced with insufficient information on the types and relative advantages of available technologies. We reviewed the literature for studies of nests that used cameras and summarized them based on study objective and the type of technology used. We also designed and tested two video systems that we used for three nest predator and behavioral studies. We found 327 studies that recorded 255 bird species spanning 19 orders. Cameras were most commonly used to study nest predators …

Forest Bioenergy Feedstock Harvesting Effects On Water Supply, Daniel G. Neary, Karen A. Koestner

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Water flowing from forested catchments, both unmanaged and managed, is highly valued in terms of both quantity and quality. Increasing energy production using wood feedstocks produces varying degrees of impacts and thereby raises concerns about environmental impacts on the highly valued water supply resources of forest ecosystems. The term water supply encompasses both key components of water quantity and water quality. Water quantity considers the amount of increases or decreases, timing, consistency, and relative magnitude of water yields. Plant nutrients (anions and cations), fertilizers, herbicides, ash additions, temperature, dissolved oxygen, pH, bacteria, and sediment comprise water quality. Within the life …

Hatching And Fledging Times From Grassland Passerine Nests, Pamela J. Pietz, D.A. Granfors, Todd Grant

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

Accurate estimates of fledging age are needed in field studies to avoid inducing premature fledging or missing the fledging event. Both may lead to misinterpretation of nest fate. Correctly assessing nest fate and length of the nestling period can be critical for accurate calculation of nest survival rates. For researchers who mark nestlings, knowing the age at which their activities may cause young to leave nests prematurely could prevent introducing bias to their studies. We estimated fledging ages from grassland passerine nests monitored from hatching through fledging with miniature video cameras in North Dakota and Minnesota during 1996-2001. We compared …

The Relationship Between Male Moth Density And Female Mating Success In Invading Populations Of Lymantria Dispar, Patrick C. Tobin, Ksenia S. Onufrieva, Kevin W. Thorpe

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The successful establishment of non-native species in new areas can be affected by many factors including the initial size of the founder population. Populations comprised of fewer individuals tend to be subject to stochastic forces and Allee effects (positive-density dependence), which can challenge the ability of small founder populations to establish in a new area. Although the conceptual relationship between initial colony size and establishment success has been previously documented, it is not trivial to estimate precisely the colony size needed to ensure colony persistence. Over the last 40 years, there have been many studies on the probability of mating …

Bird Productivity And Nest Predation In Agricultural Grasslands, C.A. Ribic, Michael Guzy, Travis Anderson, David Sample, Jamie Nack

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

Effective conservation strategies for grassland birds in agricultural landscapes require understanding how nesting success varies among different grassland habitats. A key component to this is identifying nest predators and how these predators vary by habitat. We quantified nesting activity of obligate grassland birds in three habitats [remnant prairie, cool-season grass Conservation Reserve Program (CRP) fields, and pastures) in southwest Wisconsin, 2002-2004. We determined nest predators using video cameras and examined predator activity using track stations. Bobolink (Dolichonyx oryzivorus) and Henslow's Sparrow (Ammodramus henslowii) nested primarily in CRP fields, and Grasshopper Sparrow (A. savannarum) in …

Geology Of The Early Arikareean Sharps Formation On The Pine Ridge Indian Reservation And Surrounding Areas Of South Dakota And Nebraska, Thomas H. Mcconnell, Joseph N. Dibenedetto

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Based on geologic mapping, measured sections, and lithologic correlations, the local features of the upper and lower type areas of the Early Arikareean (30.8–20.6 million years ago) Sharps Formation are revised and correlated. The Sharps Formation above the basal Rockyford Member is divided into two members of distinct lithotypes. The upper 233 feet of massive siltstones and sandy siltstones is named the Gooseneck Road Member. The middle member, 161 feet of eolian volcaniclastic siltstones with fluvially reworked volcaniclastic lenses and sandy siltstone sheets, is named the Wolff Camp Member. An ashey zone at the base of the Sharps Formation is …

Conservation Implications When The Nest Predators Are Known, Frank Thompson, C.A. Ribic

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

Conservation and management of passerines has largely focused on habitat manipulation or restoration because the natural communities on which these birds depend have been destroyed and fragmented. However, productivity is another important aspect of avian conservation, and nest predation can be a large source of nesting mortality for passerines. Recent studies using video surveillance to identify nest predators allow researchers to start evaluating what methods could be used to mitigate nest predation to help passerines of conservation concern. From recent studies, we identified latitudinal and habitat-related patterns in the importance of predator groups that depredate passerine nests. We then reviewed …

Chapter 5: Connecting Landscape Fragments Through Riparian Zones, Gary Bentrup, Mike Dosskey, Gary Wells, Michele Schoeneberger

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

5.1 Forest Loss and Ecosystem Services

Many formerly forested regions have been largely cleared and are now important crop and livestock producing lands (Fig. 5.1 ). This is true of many parts of the world including United States’ southeastern coastal plain, Brazil’s rainforests, Northern Europe’s lowlands, China’s northeastern plains, Indonesia’s lowlands, and floodplains of most of the world’s large rivers. Through widespread conversion of forests to intensively-managed agricultural uses, these countries have created highly productive agricultural economies.

Environmental issues have arisen as consequences of the loss and fragmentation of forests, including soil erosion, water pollution, and fi sh and wildlife …

Wolf Population Dynamics In The U.S. Northern Rocky Mountains Are Affected By Recruitment And Human-Caused Mortality, Justin A. Gude, Michael S. Mitchell, Robin E. Russell, Carolyn A. Sime, L. David Mech, Robert R. Ream

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

Reliable analyses can help wildlife managers make good decisions, which are particularly critical for controversial decisions such as wolf (Canis lupus) harvest. Creel and Rotella (2010) recently predicted substantial population declines in Montana wolf populations due to harvest, in contrast to predictions made by Montana Fish, Wildlife and Parks (MFWP). We replicated their analyses considering only those years in which field monitoring was consistent, and we considered the effect of annual variation in recruitment on wolf population growth. Rather than assuming constant rates, we used model selection methods to evaluate and incorporate models of factors driving recruitment and …

Ducks And Passerines Nesting In Northern Mixed-Grass Prairie Treated With Fire, Todd A. Grant, Terry L. Shaffer, Elizabeth M. Madden, Gordon B. Berkey

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

Prescribed fire is an important, ecology-driven tool for restoration of grassland systems. However, prescribed fire remains controversial for some grassland managers because of reported reductions in bird use of recently burned grasslands. Few studies have evaluated effects of fire on grassland bird populations in the northern mixed-grass prairie region. Fewer studies yet have examined the influence of fire on nest density or survival. In our review, we found no studies that simultaneously examined effects of fire on duck and passerine nesting. During 1998–2003, we examined effects of prescribed fire on the density of upland-nesting ducks and passerines nesting in north-central …

Nebraska Center for Virology: Faculty Publications

This study aimed to determine the seroprevalence of Kaposi’s sarcoma-associated herpesvirus (KSHV) and related factors in men who have sex with men (MSM) in China. A total of 208 subjects were recruited from eastern China from 2008 to 2009. Plasma samples were collected and screened for KSHV, HIV and syphilis. Overall, KSHV seroprevalence was 32·7% in the subjects. About 92·7% of subjects reported having ever had anal sex with a man, of whom 67·8% had receptive anal sex and 77·9% had insertive anal sex. About 93·1% of the study participants reported having had oral sex with a man, of whom …

Human Herpesvirus 8 Seroprevalence, China, Tiejun Zhang, Xiaodan Shao, Yue Chen, Tao Zhang, Veenu Minhas, Charles Wood, Na He

Nebraska Center for Virology: Faculty Publications

To summarize the seroprevalence of human herpesvirus 8 (HHV-8) in mainland China, we conducted a systematic review and meta-analysis based on available literature. Data show that differences in HHV-8 prevalence vary considerably among different ethnic groups and geographic regions. Blood-borne transmission could be a potential route for HHV-8 infection in China.

Project Risk And Appeals In U.S. Forest Service Planning, Marc J. Stern, S. Andrew Predmore, Wayde C. Morse, David N. Seesholtz

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The National Environmental Policy Act (NEPA) requires U.S. Forest Service planning processes to be conducted by interdisciplinary teams of resource specialists to analyze and disclose the likely environmental impacts of proposed natural resource management actions on Forest Service lands. Multiple challenges associated with these processes have been a source of frustration for the agency. One of these challenges involves administrative appeals through which public entities can challenge a Forest Service decision following a NEPA process. These appeals instigate an internal review process and can result in an affirmation of the Forest Service decision, a reversal of that decision, or additional …

The Forgotten Gothic: Short Stories From The British Literary Annuals, 1823-1831, Katherine D. Harris Ph.D.

Faculty Research, Scholarly, and Creative Activity

This collection of gothic short stories takes us further than perhaps eighteenth or nineteenth-century scholars are comfortable with – to extend our discussions about the Gothic in such a way that the tradition does not die at 1820, as is purported by Robert Mayo. We will, however, move past the deaths of Shelley, Keats and Byron – the spokespersons for the second wave of traditional Romanticism. Queen Victoria won’t ascend to the throne for another six years, and Tennyson has not yet become the powerhouse poet who will eventually rise to Poet Laureate of England. Scholars touted 1820-1830 as a …
