HIV mutates rapidly and infects CD4⁺ T cells, especially when they are activated. A vaccine targeting conserved, essential viral elements while limiting CD4⁺ T cell activation could be effective. Learning from natural immunity observed in a group of highly HIV-1 exposed seronegative Kenyan female sex workers, we are testing a novel candidate HIV vaccine targeting the 12 viral protease cleavage sites (PCSs) (the PCS vaccine), in comparison with a vaccine targeting full-length Gag and Env (the Gag/Env vaccine) in a Mauritian cynomolgus macaque/SIV model. In this study we evaluated these vaccines for induction of mucosal antibodies to SIV …

Restoration Of Tropical Seagrass Beds Using Wild Bird Fertilization And Sediment Regrading, W. Judson Kenworthy, Margaret O. Hall, Kamille K. Hammerstrom, Manuel Merello, Arthur Schwartzschild

United States Department of Commerce: Staff Publications

Shallow water seagrass meadows are frequently damaged by recreational and commercial vessels. Severe injury occurs where propeller scarring, hull groundings and mooring anchors uproot entire plants, excavate sediments, and modify the biophysical properties of the substrate. In climax tropical seagrass communities dominated by Thalassia testudinum (turtlegrass), natural recovery in these disturbances can take several years to decades, and in some environmental conditions may not occur at all. During the recovery period, important ecological services provided by seagrasses are absent or substantially diminished and injured meadows can degrade further in response to natural disturbances, e.g. strong currents and severe storms. To …

The Flathead Catfish Invasion Of The Great Lakes, Pam L. Fuller, Gary E. Whelan

United States Geological Survey: Staff Publications

A detailed review of historical literature andmuseumdata revealed that flathead catfish were not historically native in the Great Lakes Basin, with the possible exception of a relict population in Lake Erie. The species has invaded Lake Erie, Lake St. Clair, Lake Huron, nearly all drainages in Michigan, and the Fox/Wolf and Milwaukee drainages in Wisconsin. They have not been collected from Lake Superior yet, and the temperature suitability of that lake is questionable. Flathead catfish have been stocked sparingly in the Great Lakes and is not the mechanism responsible for their spread. A stocking in 1968 in Ohio may be …

Past Role And Future Outlook Of The Conservation Reserve Program For Supporting Honey Bees In The Great Plains, Clint R.V. Otto, Haochi Zheng, Alisa L. Gallant, Rich Iovanna, Benjamin L. Carlson, Matthew D. Smart, Skip Hyberg

United States Geological Survey: Staff Publications

Human dependence on insect pollinators continues to grow even as pollinators face global declines. The Northern Great Plains (NGP), a region often referred to as America’s last honey bee (Apis mellifera) refuge, has undergone rapid land-cover change due to cropland expansion and weakened land conservation programs. We conducted a trend analysis and estimated conversion rates of Conservation Reserve Program (CRP) enrollments around bee apiaries from 2006 to 2016 and developed models to identify areas of habitat loss. Our analysis revealed that NGP apiaries lost over 53% of lands enrolled in the CRP, and the rate of loss was highest in …

Extracellular Superoxide Dismutase (Sod3) Regulates Oxidative Stress At The Vitreoretinal Interface, Katherine J. Wert, Gabriel Velez, Madeline R. Cross, Brett A. Wagner, Melissa L. Teoh-Fitzgerald, Garry R. Buettner, J. Jason Mcanany, Alicia Olivier, Stephen H. Tsang, Matthew M. Harper, Frederick E. Domann, Alexander G. Bassuk, Vinit B. Mahajan

United States Department of Veterans Affairs: Publications

Oxidative stress is a pathogenic feature in vitreoretinal disease. However, the ability of the inner retina to manage metabolic waste and oxidative stress is unknown. Proteomic analysis of antioxidants in the human vitreous, the extracellular matrix opposing the inner retina, identified superoxide dismutase-3 (SOD3) that localized to a unique matrix structure in the vitreous base and cortex. To determine the role of SOD3, Sod3^-/- mice underwent histological and clinical phenotyping. Although the eyes were structurally normal, at the vitreoretinal interface Sod3^-/- mice demonstrated higher levels of 3-nitrotyrosine, a key marker of oxidative stress. Pattern electroretinography also showed physiological …

The Pothole Hydrology-Linked Systems Simulator (Phyliss)—Development And Application Of A Systems Model For Prairie-Pothole Wetlands, Owen P. Mckenna, David M. Mushet, Eric J. Scherff, Kyle I. Mclean, Christopher T. Mills

United States Geological Survey: Publications

The North American Prairie Pothole Region covers about 770,000 square kilometers of the United States and Canada (including parts of 5 States and 3 provinces: North Dakota, South Dakota, Montana, Minnesota, Iowa, Saskatchewan, Manitoba, and Alberta). The Laurentide Ice Sheet shaped the landscape of the region about 12,000 to 14,000 years ago. The retreat of the ice sheet left behind low-permeability glacial till and a landscape dotted with millions of depressions known today as prairie potholes. The wetlands that subsequently formed in these depressions, prairie-pothole wetlands, provide critical migratory-bird habitat and support dynamic aquatic communities. Extensive grasslands and productive agricultural …

Anxiety And Depression During Childhood And Adolescence: Testing Theoretical Models Of Continuity And Discontinuity, Joseph R. Cohen, Arthur R. Andrews, Megan M. Davis, Karen D. Rudolph

Department of Psychology: Faculty Publications

The present study sought to clarify the trajectory (i.e., continuous vs. discontinuous) and expression (i.e., homotypic vs. heterotypic) of anxiety and depressive symptoms across childhood and adolescence. We utilized a state-of-the-science analytic approach to simultaneously test theoretical models that describe the development of internalizing symptoms in youth. In a sample of 636 children (53% female; M age = 7.04; SD age = 0.35) self-report measures of anxiety and depression were completed annually by youth through their freshman year of high school. For both anxiety and depression, a piecewise growth curve model provided the best fit for the data, with symptoms …

Social Contact Patterns Can Buffer Costs Of Forgetting In The Evolution Of Cooperation, Jeffrey R. Stevens, Jan K. Woike, Lael J. Schooler, Stefan Lindner, Thorsten Pachur

Jeffrey Stevens Publications

Analyses of the evolution of cooperation often rely on two simplifying assumptions: (i) individuals interact equally frequently with all social network members and (ii) they accurately remember each partner's past cooperation or defection. Here, we examine how more realistic, skewed patterns of contact—in which individuals interact primarily with only a subset of their network's members—influence cooperation. In addition, we test whether skewed contact patterns can counteract the decrease in cooperation caused by memory errors (i.e. forgetting). Finally, we compare two types of memory error that vary in whether forgotten interactions are replaced with random actions or with actions from previous …

Mesotocin Influences Pinyon Jay Prosociality, Juan Duque, Whitney Leichner, Holly Ahmann, Jeffrey R. Stevens

Jeffrey Stevens Publications

Many species exhibit prosocial behavior, in which one individual’s actions benefit another individual, often without an immediate benefit to itself. The neuropeptide oxytocin is an important hormonal mechanism influencing prosociality in mammals, but it is unclear whether the avian homologue mesotocin plays a similar functional role in birds. Here, we experimentally tested prosociality in pinyon jays (Gymnorhinus cyanocephalus), a highly social corvid species that spontaneously shares food with others. First, we measured prosocial preferences in a prosocial choice task with two different payoff distributions: Prosocial trials delivered food to both the subject and either an empty cage or a partner …

Poor Sleep Health In American Adults: Implications For Screening In Civil Aviation, Melissa E. Gear

Master of Public Health Program Student Publications

Background: Poor sleep health is increasingly prevalent in the United States (US) adult population and contributes to fatigue. Fatigue is a significant safety hazard within civilian aviation, yet data regarding the prevalence of inadequate sleep in this population is sparse. Are there demographic characteristics which put individual at risk of not obtaining adequate sleep which should trigger screening during the medical certification process?

Methods: This cross-sectional study used National Health Interview Survey 2014-2016 data from US adults aged 18 to 65 to observe the relationship of demographic, socioeconomic, health, and behavioral characteristics with reported inadequate sleep duration and quality (trouble …

The Art Of Listening: Listening Skill Development, Classical Music Appreciation, And Personal Response Through Visual Art In A Middle School Program, Christina Smiraglia, Gordon Divine Asaah, Hanako Sawada Lacerda

Research & Issues in Music Education

Although many programs aim to develop students’ listening skills and promote the appreciation of Western classical music, relatively few such programs incorporate visual art. This study examined the perceived effectiveness of the Edinburgh International Festival’s (EIF) Art of Listening program in reaching its stated goals to: develop skills for listening, encourage the enjoyment of listening to Western classical music, break down preconceptions held about Western classical music, cultivate a deeper relationship with the imagination through music and art, and encourage students’ personal responses to music. Focusing primarily on the first three goals, this study gathered data from 78 students from …

Standing Dead Trees Are A Conduit For The Atmospheric Flux Of Ch4 And Co2 From Wetlands, Mary Jane Carmichael, Ashley M. Helton, Joseph C. White, William K. Smith

Biology Faculty Scholarship

In vegetated wetland ecosystems, plants can be a dominant pathway in the atmospheric flux of methane, a potent greenhouse gas. Although the roles of herbaceous vegetation and live woody vegetation in this flux have been established, the role of dead woody vegetation is not yet known. In a restored wetland of North Carolina’s coastal plain, static flux chambers were deployed at two heights on standing dead trees to determine if these structures acted as a conduit for methane emissions. Methane fluxes to the atmosphere were measured in five of the chambers, with a mean flux of 0.4±0.1 mg m-2 h-1. …

“A Spirit That Can Never Be Told”: Commemorative Agency And The Texas A & M University Bonfire Memorial, Adam J. Gaffey, Jennifer L. Jones Barbour

Communication Studies Faculty Works

On November 18, 1999, Texas A&M University (TAMU) experienced profound tragedy when the famed Aggie Bonfıre collapsed, killing 12 students and injuring 27 others. This essay examines the rhetorical dynamics of theTAMU Bonfıre Memorial and explores how it navigates the tension created when a constitutive symbol is implicated in a moment of tragedy. Specifıcally, we use this case to explore how memorials help shape perceptions of victim agency in commemorative form. As we argue, the memorial taps into resonant modes of public reasoning—including temporal metaphors, Christian theology, and campus tradition—to imply the tragic outcome of the 1999 collapse had cause …

Research Priorities For Managing Invasive Wild Pigs In North America, James C. Beasley, Stephen S. Ditchkoff, John J. Mayer, Mark D. Smith, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

With recent increases in distribution and numbers of feral pigs (Sus scrofa; invasive wild pigs) in North America, there has been a concurrent increase in the ecological and economic effects they have had on native and anthropogenic ecosystems. Despite the amplified interest in invasive wild pig research, there remains a significant knowledge gap regarding their basic biology and ecology, the scope of the damage they cause, and the efficacy of many control strategies. Such information is important to support the successful management of invasive wild pigs throughout North America and other areas. In 2016, members of the National …

Pituophis Catenifer Sayi (Bullsnake). Agonistic Mobbing Attack., James J. Delutes Iii, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Snakes have been observed as recipients of agonistic, non-predatory attacks by individuals from other taxa towards a presumed enemy (e.g., Engeman et al. 2009. Herpetol. Rev. 40:84–85; Kaiser et. al. 2013. Herpetol. Rev. 44:329). Mobbing, an attack involving multiple individuals, has been observed against many taxa of vertebrate predators (e.g., Altmann 1956. Condor 58:241–253; Owings and Coss 1977. Behaviour 62:50–69). Snakes appear to be frequent targets for this behavior and a variety of taxa have been documented to mob snakes (e.g., Owings and Coss 1976, op. cit.). Birds, probably more than any other taxa, have been commonly observed to …

Behavioral And Spatial Responses Of Captive Coyotes To Human Activity, Jeffrey T. Schultz, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Human interactions can alter an animal’s behavior and utilization of its surroundings, and how this impacts the welfare of some captive wild animals is of growing concern. Structural enrichment shelters offer weather protection, reprieve space from other animals or humans, or resting space. Perimeter or open space may be important during periods of activity, such as foraging or play. This study addressed the effects of human activity on coyote behavioral budgeting and enclosure utilization. We predicted that human activity would affect coyote behavior and spatial utilization of enclosure space. Specifically, we hypothesized that human activity would prompt vigilant and other …

Efficacy Of Avian Radar Systems For Tracking Birds On The Airfield Of A Large International Airport, Adam C. Phillips, Siddhartha Majumdar, Brian E. Washburn, David Mayer, Ryan M. Swearingin, Edwin E. Herricks, Travis L. Guerrant, Scott F. Beckerman, Craig K. Pullins

United States Department of Agriculture Wildlife Services: Staff Publications

Avian radar technologies have the potential to serve an important role in the quantification of bird movements and determining patterns of bird use in areas where human–wildlife conflicts might occur (e.g., airports, wind-energy facilities). However, capabilities and limitations of these technologies are relatively unknown and ground-truthing studies are needed to help wildlife managers understand the biological meaning of radar information. We evaluated the efficacy of 3 X-band marine radar sensors for tracking birds and flocks of birds observed on the airfield at Chicago’s O’Hare International Airport, USA, during March 2011– November 2012.We used specific information regarding field observations of birds …

Post-Release Activity And Habitat Selection Of Rehabilitated Black Bears, Patrick J. Myers, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Despite the long history of wildlife rehabilitation and the abundance of empirical knowledge of the behavior and resource selection of wildlife species, rarely does research bridge these disciplines. Such investigations could be of value to wildlife managers and rehabilitators by revealing the suitability of the habitat at selected release sites, the wild activities, behavior, and fitness of the captive-reared individuals, and ultimately the efficacy of the rehabilitation process. Rehabilitated carnivores warrant specific attention, given that they are wide-ranging and may behave in ways that threaten human safety or interests. We investigated the behavior of orphan, rehabilitated black bear cubs ( …

Chesapeake Bay Nutria Eradication Project: 2017 Update, Margaret Pepper, Kevin Sullivan, Robert Colona, Jonathan Mcknight

United States Department of Agriculture Wildlife Services: Staff Publications

Nutria, a semi-aquatic, South American rodent, was introduced to Maryland during the early 1940s. Originally brought to the area for fur farms, the market never established and animals were released or escaped. Nutria thrived, destroying coastal wetlands which resulted in negative environmental and economic impacts to the Chesapeake Bay region. To preserve and protect valuable wetland resources, the Chesapeake Bay Nutria Eradication Project (CBNEP) was established in 2002 through a partnership between the United States Fish and Wildlife Service, the United States Department of Agriculture’s Wildlife Services, Maryland Department of Natural Resources, and many state agencies and non-governmental organizations. Since …

Mitochondrial Genome Of An Allegheny Woodrat (Neotoma Magister), Mandy Schofield, Joseph Duchamp, Jeffery L. Larkin, Timothy J. Smyser, Jacqueline M. Doyle

United States Department of Agriculture Wildlife Services: Staff Publications

The Allegheny woodrat (Neotoma magister) is endemic to the eastern United States. Population numbers have decreased rapidly over the last four decades due to habitat fragmentation, disease-related mortality, genetic isolation and inbreeding depression; however, effective management is hampered by limited genetic resources. To begin addressing this need, we sequenced and assembled the entire Allegheny woodrat mitochondrial genome. The genome assembly is 16,310 base pairs in length, with an overall base composition of 34% adenine, 27% thymine, 26% cytosine and 13% guanine. This resource will facilitate our understanding of woodrat population genetics and behavioral ecology.

Perspectives On Existing And Potential New Alternatives To Anticoagulant Rodenticides And The Implications For Integrated Pest Management, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Comprising over 1400 species worldwide, rodents are the largest taxonomic group of mammals (Nowak 1999). Rodent use of habitats is extensive and varied. Most rodent species are relatively small, secretive, prolific, adaptable, and have continuously growing incisors which require constant eroding by gnawing. Rodents are known for their high reproductive potential; however, there is much variability between species as to the age at first reproduction, size of litters, and the number of litters per year. All rodent species have ecological, scientific, social, and/or economic values. They recycle nutrients, aerate soils, distribute seeds and spores, and affect plant succession. Some provide …

Anticoagulant Rodenticides And Wildlife: Introduction, Nico W. Van Den Brink, John E. Elliott, Richard F. Shore, Barnett A. Rattner

United States Department of Agriculture Wildlife Services: Staff Publications

Rodents began to associate with humans at least from the early Neolithic era with the beginnings of systematic sequestering of food stores by humans (Cucchi and Vigne 2006; Reperant and Osterhaus 2014). About the year 541, the Justinian plague started amid the central granaries and crowded, unsanitary conditions of the later Roman cities. The resulting pandemic was the first documented example of the potentially devastating impact of commensal rodents on European society. The primary reservoir host and source of the plague was the black rat (Rattus rattus), which has widely thought to have disseminated from South-East Asia along …

Starch, Lipid, And Protein Accumulation In Nutrient-Stressed Microalgal Cells Studied Using Fourier Transform Infrared Microscopy, Gary Hastings, Jodian Thomas, Keillor Witt, Dimitri Giarikos, Reza Razeghifard

Chemistry and Physics Faculty Articles

Microalgae are fast growing organisms that can be used as feedstock for the production of biofuels. The metabolism of microalgae can be manipulated by exposing them to different environmental conditions for favoring the accumulation of lipids, carbohydrates or proteins. For example, a change in growth conditions can cause the accumulation of large amounts of lipids, representing an opportunity for biodiesel production. Monitoring changes in the composition of microalgal cells is therefore important in assessing new growth conditions. However, at present, most techniques are time consuming, invasive and expensive. Here we have used FTIR microscopy to quantify lipid, protein, and starch …

“They Said I Have A Lot To Learn”: How Teacher Feedback Influences Advanced University Students’ Views Of Writing, Dana Ferris

Journal of Response to Writing

This study examines the relationship between students’ memories of teacher feedback and these students’ writing and attitudes toward and enjoyment of writing. More than 8,500 survey responses were collected from advanced undergraduate students in a large university writing program. A question about the characteristics of teacher feedback received by student respondents was examined both quantitatively and qualitatively. Second, responses to a different survey question about students’ attitudes toward writing were statistically compared with their reported memories of teacher feedback. Responses to the teacher feedback and writing attitudes questions from different student subgroups (analyzed by first language backgrounds and by when …
