Greater Sage-Grouse Nest Survival In Northwestern Wyoming, Jimmy D. Taylor Ii, R. Douglas Holt, Elizabeth K. Orning, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Nest survival, along with female survival and chick survival, is the most important vital rates to population growth of greater sage-grouse (Centrocercus urophasianus; sage-grouse). We used global positioning system and very high-frequency transmitters on female sage-grouse to identify 204 nests and monitor incubation on 5 sites in the Bighorn Basin, Wyoming from 2011 to 2014; we determined nest fate and identified predators with camera traps. We used an information-theoretic approach to compare 6 a priori nest survival models. Nest survival was best described by a model that included differences across study sites and ranged from 0.20±0.01 (SE) to …

Den Use And Heterothermy During Winter In Free-Living, Suburban Striped Skunks, Tad C. Theimer, Cory T. Williams, Shylo R. Johnson, Amy T. Gilbert, David L. Bergman, C. Loren Buck

United States Department of Agriculture Wildlife Services: Staff Publications

Many mammals use heterothermy to meet challenges of reduced food availability and low temperatures, but little is known about the prevalence of heterothermy in wild mesocarnivores. We monitored body temperature (T_b) in free-living striped skunks (Mephitis mephitis) through winter 2015–2016 in suburban Flagstaff, Arizona, a high-elevation site that experiences temperate winters. Subcutaneous T_b and heterothermy index (HI) were significantly affected by ambient temperature, and varied significantly across 7 skunks in midwinter. Twenty-one of 36 (58%) unique diurnal dens used by skunks were associated with human structures, and although females were found in dens under houses …

Rising Fluoroquinolone Resistance In Campylobacter Isolated From Feedlot Cattle In The United States, Yizhi Tang, Orhan Sahin, Nada Pavlovic, Jeff Lejeune, James C. Carlson, Zuowei Wu, Lei Dai, Qijing Zhang

United States Department of Agriculture Wildlife Services: Staff Publications

Antibiotic resistance, particularly to fluoroquinolones and macrolides, in the major foodborne pathogen Campylobacter is considered a serious threat to public health. Although ruminant animals serve as a significant reservoir for Campylobacter, limited information is available on antibiotic-resistant Campylobacter of bovine origin. Here, we analyzed the antimicrobial susceptibilities of 320 C. jejuni and 115 C. coli isolates obtained from feedlot cattle farms in multiple states in the U.S. The results indicate that fluoroquinolone resistance reached to 35.4% in C. jejuni and 74.4% in C. coli, which are significantly higher than those previously reported in the U.S. While all fluoroquinolone resistant …

Seasonal Effects Of Wind Conditions On Migration Patterns Of Soaring American White Pelican, Javier Gutierrez Illan, Guiming Wang, Fred L. Cunningham, D. Tommy King

United States Department of Agriculture Wildlife Services: Staff Publications

Energy and time expenditures are determinants of bird migration strategies. Soaring birds have developed migration strategies to minimize these costs, optimizing the use of all the available resources to facilitate their displacement. We analyzed the effects of different wind factors (tailwind, turbulence, vertical updrafts) on the migratory flying strategies adopted by 24 satellite-tracked American white pelicans (Pelecanus erythrorhynchos) throughout spring and autumn in North America. We hypothesize that different wind conditions encountered along migration routes between spring and autumn induce pelicans to adopt different flying strategies and use of these wind resources. Using quantile regression and fine-scale atmospheric …

Changes In White Cell Estimates And Plasma Chemistry Measurements Following Oral Or External Dosing Of Double-Crested Cormorants, Phalacocorax Auritus, With Artificially Weathered Mc252 Oil, Karen M. Dean, Steven J. Bursian, Dave Cacela, Michael W. Carney, Fred L. Cunningham, Brian S. Dorr, Katie C. Hanson-Dorr, Kate A. Healy, Katherine E. Horak, Jane E. Link, Ian Lipton, Andrew K. Mcfadden, Moira A. Mckernan, Kendal E. Harr

United States Department of Agriculture Wildlife Services: Staff Publications

Scoping studies were designed whereby double-crested cormorants (Phalacocorax auritus) were dosed with artificially weathered Deepwater Horizon (DWH) oil either daily through oil injected feeder fish, or by application of oil directly to feathers every three days. Preening results in oil ingestion, and may be an effective means of orally dosing birds with toxicant to improve our understanding of the full range of physiological effects of oral oil ingestion on birds. Blood samples collected every 5–6 days were analyzed for a number of clinical endpoints including white blood cell (WBC) estimates and differential cell counts. Plasma biochemical evaluations were …

Influence Of Precipitation And Crop Germination On Resource Selection By Mule Deer (Odocoileus Hemionus) In Southwest Colorado, Emily M. Carrollo, Heather E. Johnson, Justin W. Fischer, Matthew Hammond, Patricia D. Dorsey, Charles Anderson, Kurt C. Vercauteren, W. David Walter

United States Department of Agriculture Wildlife Services: Staff Publications

Mule deer (Odocoileus hemionus) populations in the western United States provide many benefits to local economies but can also cause considerable damage to agriculture, particularly damage to lucrative crops. Limited information exists to understand resource selection of mule deer in response to annual variation in crop rotation and climatic conditions. We tested the hypothesis that mule deer select certain crops, and in particular sunflower, based on annual climatic variability. Our objective was to use movements, estimates of home range, and resource selection analysis to identify resources selected by mule deer. We used annually-derived crop-specific datasets along with Global …

Effective Dose And Persistence Of Rhodamine-B In Wild Pig Vibrissae, Sarah C. Webster, Fred L. Cunningham, John C. Kilgo, Mark A. Vukovich, Olin E. Rhodes Jr., James C. Beasley

United States Department of Agriculture Wildlife Services: Staff Publications

As a result of substantial ecological and economic damage attributed to wild pigs (Sus scrofa), there is international interest in using pharmaceutical baits to control populations. To assess the efficacy and specificity of baiting programs, chemical biomarkers can be used to evaluate uptake of pharmaceutical baits. Rhodamine B (RB) is known to be an effective biomarker in wild pigs. However, significant data gaps exist regarding the minimum effective dosage and persistence of RB in wild pigs. We used a controlled doubleblind study experiment conducted in spring of 2014 on the Savannah River Site, Aiken, South Carolina, USA, wherein …

Evaluating The Impact Of An Exotic Plant Invasion On Rodent Community Richness And Abundance, Trinity N. Smith, Eric M. Gese, Bryan M. Kluever

United States Department of Agriculture Wildlife Services: Staff Publications

Cheatgrass (Bromus tectorum), Russian thistle (Salsola kali), and tall tumblemustard (Sisymbrium altissimum) are nonnative plants widely distributed throughout the desert and shrubsteppe communities of the western United States. The impact of these invaders on plant community structure, form, and function has been well documented, but investigations determining the impacts of this cumulative invasion on terrestrial vertebrates have not been undertaken. Our objective was to assess community-level rodent responses to changes in plant community features, with an emphasis on dominance of invasive plant species. We sampled rodent and plant communities in the Great Basin Desert …

The Effects Of Demographic, Social, And Environmental Characteristics On Pathogen Prevalence In Wild Felids Across A Gradient Of Urbanization, Jesse S. Lewis, Kenneth A. Logan, Mat W. Alldredge, Scott Carver, Sarah N. Bevins, Michael Lappin, Sue Vandewoude, Kevin R. Crooks

United States Department of Agriculture Wildlife Services: Staff Publications

Transmission of pathogens among animals is influenced by demographic, social, and environmental factors. Anthropogenic alteration of landscapes can impact patterns of disease dynamics in wildlife populations, increasing the potential for spillover and spread of emerging infectious diseases in wildlife, human, and domestic animal populations. We evaluated the effects of multiple ecological mechanisms on patterns of pathogen exposure in animal populations. Specifically, we evaluated how ecological factors affected the prevalence of Toxoplasma gondii (Toxoplasma), Bartonella spp. (Bartonella), feline immunodeficiency virus (FIV), and feline calicivirus (FCV) in bobcat and puma populations across wildlandurban interface (WUI), low-density exurban development, and wildland habitat …

Bird Feeders As Locations For Skunk Uptake Of Oral Rabies Vaccine Baits, Tad C. Theimer, Tisheena Talk, Shylo Johnson, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

Significantly more (54%, P=0.003) placebo baits placed under 26 bird feeders in Arizona, US were removed by striped skunks (Mephitis mephitis) than at paired, nonfeeder locations (19%). Baiting at bird feeders could supplement traditional oral rabies vaccine bait placement in urban-suburban areas while engaging the public in rabies control efforts.

Efficacy Of An Acoustic Hailing Device As An Avian Dispersal Tool, Peter E. Schlichting, Amanda E. Holland, James C. Beasley, Albert L. Bryan, Robert A. Kennamer, Travis L. Devault, Bradley F. Blackwell, Olin E. Rhodes Jr.

United States Department of Agriculture Wildlife Services: Staff Publications

Bird strikes are a major safety and financial concern for modern aviation. Audible stimuli are common bird dispersal techniques, but their effectiveness is limited by the saliency and relevance of the stimulus. Furthermore, high ambient sound levels present at airfields might require that effective audible stimuli rely more on total volume (i.e., exceeding physiological tolerances) than ecological relevance. Acoustic hailing devices (AHD) are capable of sound output with a narrow beamwidth and at volumes high enough to cause physical discomfort at long distances. We tested the effectiveness of anAHD as a dispersal tool on freeranging birds recognized as hazardous to …

Clinostomum Album N. Sp. And Clinostomum Marginatum (Rudolphi, 1819), Parasites Of The Great Egret Ardea Alba L. From Mississippi, Usa, Thomas G. Rosser, Neely R. Alberson, Ethan T. Woodyard, Fred L. Cunningham, Linda M. Pote, Matt J. Griffin

United States Department of Agriculture Wildlife Services: Staff Publications

Members of the genus Clinostomum Leidy, 1856, colloquially known as yellow grubs, are cosmopolitan parasites of piscivorous birds, freshwater snails, fish and amphibians. In the southeastern United States, piscivorous birds present a continuous challenge for producers of farm-raised catfish. Ciconiiform birds are common hosts of Clinostomum spp. in North America and are endemic on most commercial catfish operations. The great egret Ardea albaL. is an avian predator often found foraging on commercial catfish operations, but to date the trematode fauna of great egrets preying on catfish ponds remains mostly understudied. Thirteen great egrets were captured from commercial catfish ponds …

Bayesian Model-Based Age Classification Using Small Mammal Body Mass And Capture Dates, Nathaneal Lichti, Kenneth F. Kellner, Timothy J. Smyser, Scott A. Johnson

United States Department of Agriculture Wildlife Services: Staff Publications

Accurate age determination is a fundamental prerequisite for demographic studies as well as population monitoring efforts that provide information for management and conservation. Yet, common age determination methods suffer from low accuracy rates, impose additional handling and time costs on animals and biologists, or rely on invasive techniques such as tooth extraction. We introduce an alternative, mixture modeling approach for age determination that exploits mammalian growth patterns to classify newly encountered animals as juveniles or adults, and present an example analysis that classifies Allegheny woodrats based solely on their capture dates and mass at capture, in combination with data from …

Development Of Known-Fate Survival Monitoring Techniques For Juvenile Wild Pigs (Sus Scrofa), David A. Keiter, John C. Kilgo, Mark A. Vukovich, Fred L. Cunningham, James C. Beasley

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Wild pigs are an invasive species linked to numerous negative impacts on natural and anthropogenic ecosystems in many regions of the world. Robust estimates of juvenile wild pig survival are needed to improve population dynamics models to facilitate management of this economically and ecologically important invasive species. Despite this critical knowledge gap, to date no successful known-fate study of wild piglet survival (age) has been conducted, due to a lack of appropriate method for this species. Aims. To aid in locating and tagging neonates, we piloted the use of vaginal implant transmitters (VITs) in adult wild pigs and evaluated …

Survival And Habitat Selection Of Canada Geese During Autumn And Winter In Metropolitan Chicago, Usa, Brett E. Dorak, Michael P. Ward, Michael W. Eichholz, Brian E. Washburn, Timothy P. Lyons, Heath M. Hagy

United States Department of Agriculture Wildlife Services: Staff Publications

Winter distribution and resource use of animals is driven by myriad interacting biotic and abiotic factors. Urban areas provide sanctuaries from hunting for game animals and may have thermal benefits during winter through reduced thermoregulatory costs. We deployed cellular GPS transmitters affixed to neck collars of 41 Canada Geese (Branta canadensis) in the Greater Chicago Metropolitan Area (GCMA) of northeastern Illinois, USA, to determine habitat selection and survival during autumn and winter. Canada Geese selected green spaces (59.8%) in greater proportion than available (14%), but they also regularly used industrial urban habitats such as rooftops and rail yards …

Wetland Bird Abundance And Safety Implications For Military Aircraft Operations, Kent Andersson, Craig A. Davis, Bradley F. Blackwell, Jason R. Heinen

United States Department of Agriculture Wildlife Services: Staff Publications

Wetlands with associated avifauna can pose a substantial hazard to aviation safety, potentially increasing bird–aircraft collision (strike) risk when located near air operations areas.We modeled year-round use by wetland avifauna of Drummond Flats Wildlife Management Area (Drummond Flats), a wetland complex located within 10 km of Vance Air Force Base (AFB), Enid, Oklahoma, USA. Our objectives were to 1) quantify seasonal avifauna abundances at Drummond Flats; 2) test a priori models reflecting use by bird species recognized as hazardous to aviation safety relative to environmental factors including flooded wetland habitat and vegetation cover; 3) use these models to predict maximal …

Participant Perspectives On Housing And Landlords In A Canadian Housing First Program, Timothy Macleod

Theses and Dissertations (Comprehensive)

Housing First (HF) is an evidence-based approach to housing and services for adults who are chronically homeless and have a psychiatric disability. Research has demonstrated that HF rapidly ends homelessness but less in known about how participants experience their housing environments and landlords. This study is a part of a larger Canadian randomized field trial of HF that included qualitative interviews with participants in five cities. The narratives of 127 participants randomized to HF (n=82) or Treatment as Usual (TAU, n=45) were collected with regard to their perceptions of housing and landlords. Participant narratives were analyzed using thematic analysis and …

Latin America In Theories Of Territorial Rights / América Latina En Las Teorías De Los Derechos Territoriales, Avery Kolers

Faculty and Staff Scholarship

“Who owns it?” is a surprisingly confusing question when applied to territory. Each word opens up puzzles: who can “own” territory? What is “ownership” in this context? How can it be justified in a way that could convince an outsider? These questions are particularly salient in the Latin American context, where multiple distinct kinds of land disputes converge. This paper canvasses two familiar approaches to these questions: the Kantian autochthony view, and the Lockean efficiency view. Neither view answers the question as to “who owns it” in all its complexity. The paper then defends an alternative approach grounded in recognition …

What Students Do With Words: Language Use And Communicative Function In Full And Partial Immersion Classrooms, Katherine Christoffersen

Writing and Language Studies Faculty Publications

Over the past 35 years, language immersion programs have been steadily increasing in number throughout the U.S. The popularity of these diverse, linguistically complex educational programs has led to a rather extensive body of research on language immersion and dual language contexts. Research, however, has thus far focused primarily on the quantification of language use (the amount of target language versus first language use) in different settings and with different interlocutors. Very few studies have probed the interesting and significant sociolinguistic question of what students ‘do’ with languages in the classroom. The present study fills this research gap by investigating …

Dear John, You Are A Human Trafficker, Mary Graw Leary

Scholarly Articles

Human trafficking finally presents a crime that appropriately shifts the culpability from the abused to the abuser. As the heinous world of human trafficking is studied and more is understood about its inner workings, we can no longer conflate victimization with over-criminalization. The purpose of this paper is to shine light on the force and fraud that perpetuates the enslavement of victims who are sexually trafficked. Beginning with the Mann Act passed by Congress and up until more recently, the Trafficking Victims Protection Act, this paper traces the historical and societal shifts that are necessary to situate Sex Purchasers in …

Risks And Rewards Of Externships: Exploring Goals And Methods, Leah Wortham, Linda F. Smith, Jeff Giddings

Scholarly Articles

This article grew from a presentation relating externship clinical programs to the theme of the July 2016 International Journal of Clinical Legal Education and Association of Canadian Legal Education conference: The Risks and Rewards of Clinical Legal Education Programmes. Externships or field placement programs involve students placed away from the law school and supervised by a person who is not employed by the law school. Externships offer many potential rewards for students as well as other stakeholders, including especially community institutions. But there are also risks—risks that the externship will be expected to accomplish too much with too few resources …

Privilege For Patent Agents, Megan M. La Belle

Scholarly Articles

Patent agents, in many ways, are unique operators in our legal system. They are not attorneys; yet, they are authorized by Congress to practice law before the United States Patent and Trademark Office (PTO). This unusual status raises a host of questions, including whether communications with patent agents should be privileged and, therefore, shielded from discovery. This question has become increasingly important in recent years with the rise of litigation at the Patent Trial and Appeal Board (PTAB)--an administrative tribunal created in 2011 by the America Invents Act (AIA)--where parties can be represented either by a patent attorney or a …

Enduring Originalism, Kevin C. Walsh, Jeffrey A. Pojanowski

Scholarly Articles

If our law requires originalism in constitutional interpretation, then that would be a good reason to be an originalist. This insight animates what many have begun to call the "positive turn" in originalism. Defenses of originalism in this vein are "positive" in that they are based on the status of the Constitution, and constitutional law, as positive law. This approach shifts focus away from abstract conceptual or normative arguments about interpretation and focuses instead on how we actually understand and apply the Constitution as law. On these grounds, originalism rests on a factual claim about the content of our law: …

The Mediating Effects Of Cortisol On The Relationship Between Conscientiousness And Judgments Of Learning, Katherine D. Miller

Graduate Theses/Dissertations

Cortisol assists in facilitating stress response. A peak in cortisol levels can be seen between 20 and 40 minutes after exposure to the stressful event. Judgments of learning (JOLs) are within the field of metacognition and are judgments individuals make about how well they feel they have acquired the target information. Many factors influence the accuracy of these judgments, including whether they are immediate or delayed. Conscientiousness is a characteristic of personality that is associated with responsibility and organization. Individuals high in conscientiousness are more likely to have positive health related outcomes. A relationship between conscientiousness and the appraisal of …

Late Precontact Settlement On The Northern Seward Peninsula Coast: Results Of Recent Fieldwork, Shelby L. Anderson, Justin Andrew Junge

Anthropology Faculty Publications and Presentations

Changing Arctic settlement patterns are associated with shifts in socioeconomic organization and interaction at both the inter- and intraregional levels; analysis of Arctic settlement patterns can inform research on the emergence and spread of Arctic maritime adaptations. Changes in late precontact settlement patterns in Northwest Alaska suggest significant shifts in subsistence and/or social organization, but the patterns themselves are not well understood. Prior research around Kotzebue Sound suggests three possible scenarios: (1) population decrease and dispersion from settlement centers after 550 cal bp, (2) population stability and dispersion after 550 cal bp, and (3) different settlement patterns in the northern …

On The Origin Of Superoxide Dismutase: An Evolutionary Perspective Of Superoxide-Mediated Redox Signaling., Adam J. Case

Journal Articles: Cellular & Integrative Physiology

The field of free radical biology originated with the discovery of superoxide dismutase (SOD) in 1969. Over the last 5 decades, a plethora of research has been performed in species ranging from bacteria to mammals that has elucidated the molecular reaction, subcellular location, and specific isoforms of SOD. However, while humans have only begun to study this class of enzymes over the past 50 years, it has been estimated that these enzymes have existed for billions of years, and may be some of the original enzymes found in primitive life. As life evolved over this expanse of time, these enzymes …
