Osteoarthritis In The Pelvic Limb Of Captive Cranes, Barry K. Hartup, Savannah J. Lauer, Alyson R. Manthei

Proceedings of the North American Crane Workshop

We conducted an epidemiological study of osteoarthritis (OA) among the 15 captive crane species managed at the International Crane Foundation from 1973 to 2016. A retrospective review of 714 medical records found 37 cases of OA in 13 species of cranes and a corresponding period prevalence of OA of 5%. An analysis of the living captive crane flock as of 1 October 2016 (n = 115) found 12 active cases of OA (a point prevalence of 10%), and there was a statistical association between geriatric age classification (i.e., advanced age) and the presence of OA (P < 0.01). The mean age of cranes with OA was 14 years greater than cranes without the disease (P < 0.001). The prevalence estimates of OA from this review were somewhat lower than that from study of museum specimens, but this study similarly identified the tarsal joint as the predominant location of OA lesions in cranes.

Italian Bedfellows: Tristan, Solomon & “Bestes”, Kathryn Berenson

Textile Society of America: Symposium Proceedings

Two surviving late fourteenth-century quilted furnishings, the Coperta Guicciardini in the Museo Nazinale del Bargello, Florence, and the Tristan Quilt in the Victoria and Albert Museum, London, depict scenes from the legend of Tristan, one of King Arthur’s knights. Both museums attribute the furnishings to a southern Italian atelier. Research to-date essentially treats these works as if, like Athena from the head of Zeus, they burst complete. Yet by the twelfth century Greek, Roman, Byzantine, and Norman occupation and active trade with the Levant, all had contributed to the culture of southern Italy. Prime evidence is the mosaic floor, dated …

Indian Basketry In Yosemite Valley, 19th-20th Century: Gertrude “Cosie” Hutchings Mills, Tourists And The National Park Service, Catherine K. Hunter

Textile Society of America: Symposium Proceedings

Basketry is the highest art form of Native Americans in California. I will focus on Yosemite Valley starting in the 1850s when Native Americans adapted progressively to contact with miners, settlers, and tourists. As a Research Associate at the Peabody Museum, Andover, Massachusetts, I inventoried the Native American Basket Collection. The unpublished Hutchings Mills Collection, acquired by Gertrude ‘Cosie’ Hutchings in Yosemite prior to 1900, caught my attention. In 1986, the Department of the Interior requested the collection be loaned, exchanged, or purchased as “the single most important assemblage from that period.” The collection did not leave Andover; however, one …

Shepherds And Shawls: Making Place In The Western Himalayas, Jennifer Hoover

Textile Society of America: Symposium Proceedings

Cars weave through the flocks of the Gaddi shepherds as they travel from the plains to high altitude deserts, winding along roads lined with shops selling Kullu shawls. In these ways and more, textiles are the face of the northern Indian state of Himachal Pradesh. Yet dominant discourses position both the shepherds and weavers of the region as the last hold-outs of endangered traditions. These discourses continue colonial-era assumptions of rural artisans as “primitives” in need of either protection from encroaching industrialization or motivation to modernize. Academic writings, popular visual representations, and government policies also reinforce monolithic identities of herders …

Threads, Twist And Fibre: Looking At Coast Salish Textiles, Liz Hammond-Kaarremaa

Textile Society of America: Symposium Proceedings

Coast Salish textiles are: remarkable for their quality; unusual in the fibres used; notable in their designs; singular in the innovative processes used to manufacture them. Salish textiles were determined by geography, shaped by trade, and influenced by colonization. That the textile tradition has survived is a reflection of the prestige they hold and the importance of the textiles in the Coast Salish culture. Relatively unknown and underappreciated, the older textiles deserve to be looked at with fresh eyes and modern methods that bring to light the outstanding abilities of the Coast Salish women in the creation of these important …

Ancient, Indigenous And Iconic Textile Motifs In Contemporary Fashion Case Study: Defining Concepts Through Textile Designs: Appropriation, Collaboration, Provenance And Identity, Kristin Scheel Lunde

Textile Society of America: Symposium Proceedings

This paper investigates the material and visual characteristics of certain ancient and historical textile motifs with roots in Chinese and African culture, and their sudden appearance in new geographical and cultural context. Appropriated into western contemporary textile and fashion trends, this paper examines the new roles of these designs in context of foreigness, identity, and hybridity. Their consumption and reception both within and beyond their original cultures is a central theme, and it is evident that their reception in both locations, although different, exhibits some similarities. Exploring the transcultural consumption and reception that occurs in various cultural locations this paper …

Potential Impacts Of Offshore Oil Spills On Polar Bears In The Chukchi Sea, Ryan R. Wilson, Craig Perham, Deborah P. French-Mccay, Richard Balouskus

United States Fish and Wildlife Service: Publications

Sea ice decline is anticipated to increase human access to the Arctic Ocean allowing for offshore oil and gas development in once inaccessible areas. Given the potential negative consequences of an oil spill on marine wildlife populations in the Arctic, it is important to understand the magnitude of impact a large spill could have on wildlife to inform response planning efforts. In this study we simulated oil spills that released 25,000 barrels of oil for 30 days in autumn originating from two sites in the Chukchi Sea (one in Russia and one in the U.S.) and tracked the distribution of …

Complete Genome Sequence Of Moraxella Bovis Strain Epp-63 (300), An Etiologic Agent Of Infectious Bovine Keratoconjunctivitis, John Dustin Loy, Aaron M. Dickey, Michael L. Clawson

School of Veterinary and Biomedical Sciences: Faculty Publications

We report here the complete closed genome sequence of Moraxella bovis strain Epp-63 (300) (Epp63). This strain was isolated from an infectious bovine keratoconjunctivitis (IBK) case in 1963. Since then, Epp63 has been used extensively for IBK research. Consequently, the genome sequence of Epp63 should help elucidate IBK host-pathogen interactions.

Nd’Awakananawal Babijigwezijik Wd’Elasawawôganôl: “We Wear The Clothing Of Our Ancestors”, Vera Longtoe Sheehan

Textile Society of America: Symposium Proceedings

When thinking of Native American people, a typical image is of tanned people with long dark hair wearing leather and furs in the distant past, but that is not an accurate depiction of the Abenaki people or their textiles. As an Abenaki scholar, artist, and educator, my research into the textile traditions of the Abenaki people includes archaeological evidence, primary resources, and oral history interviews. Abenakis themselves have different ideas of what it traditional because textile and fiber arts evolved over many millennia throughout N’dakinna, the Abenaki homeland which once encompassed Vermont, New Hampshire, northern Massachusetts, and parts of New …

Assessing The Feasibility Of Soil Infiltration Trenches For Highway Runoff Control On The Island Of Oahu, Hawaii, Martina Sobotkova, Jaromir Dusek, Ghasem Alavi, Laxman Sharma, Chittaranjan Ray

Nebraska Water Center: Faculty Publications

The coastal waters of Hawaii are extremely important for recreation as well as for the health of the marine environment. Non-point source pollution from storm runoff poses a great threat to surface water quality in Hawaii. The State of Hawaii Department of Transportation (HDOT) includes infiltration trenches as a best management practice (BMP) option to reduce pollution caused by stormwater runoff. HDOT guidelines state that the implementation of BMPs is needed to reduce sediment and pollutant loads to streams and the ocean. In this study, the suitability of soils adjacent to highways on Oahu for the siting of infiltration trenches …

New Insights On Hedge Ratios In The Presence Of Stochastic Transaction Costs, Elisson Andrade, Fabio Mattos, Roberto Arruda De Souza Lima

Department of Agricultural Economics: Faculty Publications

The objective of this research is to evaluate the influence on hedging decisions of a realistic set of transaction costs which are largely stochastic. The stochastic nature of some transaction costs (such as margin calls) means that their exact value is unknown when the hedge is placed, since they depend on the trajectory of futures prices during the hedge. Results are consistent with previous studies in that the introduction of transaction costs tend to affect hedge ratios. However, as opposed to the traditional literature, the introduction of stochastic costs in futures hedging can either decrease or increase hedge ratios depending …

A Tunable, Three-Dimensional In Vitro Culture Model Of Growth Plate Cartilage Using Alginate Hydrogel Scaffolds, Alek G. Erickson, Taylor D. Laughlin, Sarah M. Romereim, Catherine N. Sargus-Patino, Angela K. Pannier, Andrew T. Dudley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Defining the final size and geometry of engineered tissues through precise control of the scalar and vector components of tissue growth is a necessary benchmark for regenerative medicine, but it has proved to be a significant challenge for tissue engineers. The growth plate cartilage that promotes elongation of the long bones is a good model system for studying morphogenetic mechanisms because cartilage is composed of a single cell type, the chondrocyte; chondrocytes are readily maintained in culture; and growth trajectory is predominately in a single vector. In this cartilage, growth is generated via a differentiation program that is spatially and …

Beauty Is In The Eye Of The Beer Holder: An Initial Investigation Of The Effects Of Alcohol, Attractiveness, Warmth, And Competence On The Objectifying Gaze In Men, Abigail R. Riemer, Michelle Haikalis, Molly R. Franz, Michael Dodd, David Dilillo, Sarah Gervais

Department of Psychology: Faculty Publications

Despite literature revealing the adverse consequences of objectifying gazes for women, little work has empirically examined origins of objectifying gazes by perceivers. Integrating alcohol myopia and objectification theories, we examined the effects of alcohol as well as perceived female attractiveness, warmth, and competence on objectifying gazes. Specifically, male undergraduates (n = 49) from a large U.S. Midwestern university were administered either an alcoholic or placebo beverage. After consumption, participants were asked to focus on the appearance or personality (counterbalanced) of pictured women who were previously rated as high, average, or low in attractiveness, warmth, and competence. Replicating previous work, appearance …

Microrna Cluster Mir199a/214 Are Differentially Expressed In Female And Male Rats Following Nicotine Self-Administration, Steven T. Pittenger, Victoria L. Schaal, Dalia Moore, Rahul S. Guda, Sneh Koul, Sowmya V. Yelamanchili, Rick A. Bevins, Gurudutt Pendyala

Department of Psychology: Faculty Publications

Previous research has established sex differences associated with nicotine intake, however a significant gap in knowledge remains regarding the molecular mechanisms that govern these differences at the transcriptional level. One critical regulator of transcription are microRNAs (miRNAs). miRNAs are a family of non-coding RNAs that regulate an array of important biological functions altered in several disease states, including neuroadaptive changes within the brain associated with drug dependence. We examined the prefrontal cortex (PFC) from male and female Sprague-Dawley rats following self-administration (22 days) of nicotine or yoked saline controls using next generation RNA-Sequencing (RNA-Seq) technology and found an array of …

Plant Community Response To Disturbances In Nebraska Sandhills Upland Prairie, Josiah D. Dallmann

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Historically, disturbances shaped prairie ecosystems both directly through events like fire and soil moving by animals, as well as indirectly through dynamic rainfall patterns and periodic flux in seed availabilities. We hypothesized that the implementation of several distinct disturbance events in Nebraska Sandhills upland prairie would have measurable effects on plant community composition. We implemented mid-spring fire, soil disturbance in the form of disking, seed addition of native forbs on disked plots, as well as early summer supplemental watering (to mimic minor rainfall events during abnormally dry periods) during 2016 and 2017. Plant community response during the first and second …

Herbicide resistance is ‘wicked’ in nature; therefore, results of the many educational efforts to encourage diversification of weed control practices in the United States have been mixed. It is clear that we do not sufficiently understand the totality of the grassroots obstacles, concerns, challenges, and specific solutions needed for varied crop production systems. Weed management issues and solutions vary with such variables as management styles, regions, cropping systems, and available or affordable technologies. Therefore, to help the weed science community better understand the needs and ideas of those directly dealing with herbicide resistance, seven half-day regional listening sessions were held …

Lake Regionalization And Diatom Metacommunity Structuring In Tropical South America, Xavier Benito, Sherilyn C. Fritz, Miriam Steinitz-Kannan, Maria I. Velez, Michael M. Mcglue

Department of Earth and Atmospheric Sciences: Faculty Publications

Lakes and their topological distribution across Earth’s surface impose ecological and evolutionary constraints on aquatic metacommunities. In this study, we group similar lake ecosystems as metacommunity units influencing diatom community structure. We assembled a database of 195 lakes from the tropical Andes and adjacent lowlands (8°N–30°S and 58–79°W) with associated environmental predictors to examine diatom metacommunity patterns at two different levels: taxon and functional (deconstructed species matrix by ecological guilds). We also derived spatial variables that inherently assessed the relative role of dispersal. Using complementary multivariate statistical techniques (principal component analysis, cluster analysis, nonmetric multidimensional scaling, Procrustes, variance partitioning), we …

Hematophagous arthropods are capable of transmitting human and animal pathogens worldwide. Vector-borne diseases account for 17% of all infectious diseases resulting in 700,000 human deaths annually. Repellents are a primary tool for reducing the impact of biting arthropods on humans and animals. N,N-Diethyl-meta-toluamide (DEET), the most effective and long-lasting repellent currently available commercially, has long been considered the gold standard in insect repellents, but with reported human health issues, particularly for infants and pregnant women. In the present study, we report fatty acids derived from coconut oil which are novel, inexpensive and highly efficacious repellant compounds. These coconut fatty acids …

Muskrats, James E. Miller

Wildlife Damage Management Technical Series

The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States (Figure 1). It spends its life in aquatic habitats and is well adapted for swimming.

Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth.

Muskrats also cause damage by eating agricultural crops, other vegetation, and crayfish, mussels and other aquaculture products. Loss of vegetation …

Wild Turkeys, James E. Miller

Wildlife Damage Management Technical Series

Like other bird and mammal species whose populations have been restored through conservation efforts, wild turkeys (Figure 1) are treasured by many recreationists and outdoor enthusiasts. Wild turkeys have responded positively to wildlife habitat and population management. In some areas, however, their increased populations have led to increased damage to property and agricultural crops, and threats to human health and safety. Turkeys frequent agricultural fields, pastures, vineyards and orchards, as well as some urban and suburban neighborhoods. Because of this, they may cause damage or mistakenly be blamed for damage. Research has found that despite increases in turkey numbers and …

Growth, Fitness, And Overwinter Survival Of A Shattercane (Sorghum Bicolor Ssp. Drummondii) × Grain Sorghum (Sorghum Bicolor Ssp. Bicolor) F2 Population, Jared J. Schmidt, Melinda K. Yerka, Jeffrey F. Pedersen, John L. Lindquist

Department of Agronomy and Horticulture: Faculty Publications

Although sorghum [Sorghum bicolor (L.) Moench ssp. bicolor] is the fifth most important grain crop in terms of global production, no commercial hybrids carry genetically engineered (GE) traits for resistance to insect pests or herbicides due to regulatory concerns about gene flow to weedy relatives. However, non-GE herbicide resistance currently is being developed in grain sorghum and will likely transfer to related weeds. Monitoring the impact of this new nuclear technology on the evolution and invasiveness of related weeds requires a baseline understanding of the population biology of grain sorghum genes once they transfer to in situ weed …

Impact Of Intake On Methane Production In Growing Steers, Tom M. Winders, Bradley M. Boyd, F. Henry Hilscher Hilscher, Samodha C. Fernando, Richard Stowell, Galen E. Erickson

Nebraska Beef Cattle Reports

A study was conducted to evaluate the impact that level of intake has on methane and carbon dioxide production by growing steers. Two treatments were evaluated that included ad-libitum intake compared to limit-fed steers. The ad-libitum fed cattle had greater gains, similar feed efficiency and produced more methane and carbon dioxide per day, while the limit fed cattle produced more methane and carbon dioxide per pound of intake than the ad-libitum fed cattle.

Supplementing Rumen Undegradable Protein To Grazing Cattle, Braden C. Troyer, Bradley M. Boyd, Andrea K. Watson Watson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A pooled-analysis of previous Nebraska Beef Report Articles examined the impact of rumen undegradable protein (RUP) supplementation for cattle grazing different types of forage. Each lb of RUP supplement increased ADG by 0.63 lb/d when cattle were grazing smooth brome and 0.43 lb/d when grazing warm season grasses. Cattle did not respond to RUP when grazing summer annuals which were high (18.2%) in CP.
