Sandhill Crane Roost Selection, Human Disturbance, And Forage Resources, Aaron T. Pearse, Gary L. Krapu, David A. Brandt

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

Sites used for roosting represent a key habitat requirement for many species of birds because availability and quality of roost sites can influence individual fitness. Birds select roost sites based on numerous factors, requirements, and motivations, and selection of roosts can be dynamic in time and space because of various ecological and environmental influences. For sandhill cranes (Antigone canadensis) at their main spring staging area along the Platte River in south-central Nebraska, USA, past investigations of roosting cranes focuse donphysical channel characteristics related to perceived security as motivating roost distribution.We used 6,310 roost sites selected by 313 sandhill cranes over …

Repairing The Broken Mirror: Understanding Men's Muscularity-Focused Body Image Concerns Through The Lens Of Gender Role Conflict And Self-Compassion., Michael S. Butchko

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Psychological research pertaining to the study of men and masculinity has discerned that men are increasingly becoming dissatisfied with their bodies. However, men’s body image research has been neglected as researchers originally concluded that only women were impacted. However, the last 20 years has begun to elucidate factors and consequences of muscularity-focused body image dissatisfaction among men. Particularly, some men engage in dangerous behaviors (e.g., excessive exercise, dieting, steroid use) in order to obtain a body with large biceps, chiseled chest, and defined abdominal muscles. Also, more men are experiencing characteristics of muscle dysmorphia (MD), a subtype of body dysmorphic …

Characterization And Development Mechanism Of Apios Americana Tuber Starch, Hanyu Yangchen, Vikas Belamkar, Steven B. Cannon, Jay-Lin Jane

Department of Agronomy and Horticulture: Faculty Publications

Apios americana is a wild legume-bearing plant with edible tubers. Domestication of Apios is in progress because of the superior nutritional value and health benefits of the tuber. Objectives of this study were to: (1) characterize physicochemical properties of the Apios tuber starch; and (2) understand differences in starch structures and properties between the mother (seed) and child (progeny) tubers and the mechanism of starch development. Granules of the Apios tuber starch displayed ellipsoidal, rod, or kidney shape with diameter ranges of 1–30 m. The mother tuber starches displayed greater percentage crystallinity, larger gelatinization enthalpy-changes, longer branch-chain lengths of amylopectin, …

Genomics-Assisted Characterization Of A Breeding Collection Of Apios Americana, An Edible Tuberous Legume, Vikas Belamkar, Andrew Farmer, Nathan T. Weeks, Scott R. Kalberer, William J. Blackmon, Steven B. Cannon

Department of Agronomy and Horticulture: Faculty Publications

For species with potential as new crops, rapid improvement may be facilitated by new genomic methods. Apios (Apios americana Medik.), once a staple food source of Native American Indians, produces protein-rich tubers, tolerates a wide range of soils, and symbiotically fixes nitrogen. We report the first high-quality de novo transcriptome assembly, an expression atlas, and a set of 58,154 SNP and 39,609 gene expression markers (GEMs) for characterization of a breeding collection. Both SNPs and GEMs identify six genotypic clusters in the collection. Transcripts mapped to the Phaseolus vulgaris genome–another phaseoloid legume with the same chromosome number–provide provisional genetic …

Orm Expression Alters Sphingolipid Homeostasis And Differentially Affects Ceramide Synthase Activity, Athen N. Kimberlin, Gongshe Han, Kyle D. Luttgeharm, Ming Chen, Rebecca E. Cahoon, Julie M. Stone, Jennifer E. Markham, Teresa M. Dunn, Edgar B. Cahoon

Center for Plant Science Innovation: Faculty Publications

Sphingolipid synthesis is tightly regulated in eukaryotes. This regulation in plants ensures sufficient sphingolipids to support growth while limiting the accumulation of sphingolipid metabolites that induce programmed cell death. Serine palmitoyltransferase (SPT) catalyzes the first step in sphingolipid biosynthesis and is considered the primary sphingolipid homeostatic regulatory point. In this report, Arabidopsis (Arabidopsis thaliana) putative SPT regulatory proteins, orosomucoidlike proteins AtORM1 and AtORM2, were found to interact physically with Arabidopsis SPT and to suppress SPT activity when coexpressed with Arabidopsis SPT subunits long-chain base1 (LCB1) and LCB2 and the small subunit of SPT in a yeast ( …

Studies On Asparagine In Nebraska Wheat And Other Grains, Sviatoslav Navrotskyi

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Understanding of the contribution of environmental and genetic factors on the chemical composition of different grains is a critical issue in the area of food safety of cereal products. Numerous studies have reported that asparagine can form acrylamide, a toxic and potentially carcinogenic precursor compound, during a Milliard reaction. Therefore, studying the environmental and genetic effects that contribute to accumulation of asparagine in wheat and proso millet lines, which were grown in the state of Nebraska, is important for supporting breeding programs aimed at providing safer crops for consumers. In the realm of reduction of the asparagine concentration in wheat-based …

U. S. Mushroom Import Demand Estimation With Source Differentiated Aids And Rotterdam Models, Jun Li

Department of Agricultural Economics: Dissertations, Theses, and Student Research

While technically considered as fungi, mushrooms are often classified as vegetables because they provide many of the nutritional attributes of produce as well as meat, beans, and grains. The U.S. is the largest consumer of mushrooms and the share of imports in total consumption of mushrooms has been rising and will likely continue to rise as U.S. consumers increasingly adopt healthier diets. While most of U.S. fresh mushroom imports are from Canada, China, Mexico and South Korea, most of U.S. canned mushroom imports are from China, India, Indonesia, and the Netherlands.

The contribution of this thesis is to provide the …

Stable Engraftment Of Bifidobacterium Longum Ah1206 In The Human Gut Depends On Individualized Features Of The Resident Microbiome, María X. Maldonado-Gómez, Inés Martínez, Francesca Bottacini, Amy O’Callaghan, Marco Ventura, Douwe Van Sinderen, Benjamin Hillmann, Pajau Vangay, Dan Knights, Robert W. Hutkins, Jens Walter

Department of Food Science and Technology: Faculty Publications

Live bacteria (such as probiotics) have long been used to modulate gut microbiota and human physiology, but their colonization is mostly transient. Conceptual understanding of the ecological principles as they apply to exogenously introduced microbes in gut ecosystems is lacking. We find that, when orally administered to humans, Bifidobacterium longum AH1206 stably persists in the gut of 30% of individuals for at least 6 months without causing gastrointestinal symptoms or impacting the composition of the resident gut microbiota. AH1206 engraftment was associated with low abundance of resident B. longum and underrepresentation of specific carbohydrate utilization genes in the pre-treatment microbiome. …

Comparison Of Hermetic Storage Of Wheat With Traditional Storage Methods In India, Pavel Somavat, Haibo Huang, Sunil Kumar, Mukesh K. Garg, Mary-Grace C. Danao, Vijay Singh, Marvin R. Paulsen, Kent D. Rausch

Department of Food Science and Technology: Faculty Publications

India is among the countries experiencing high postharvest losses. Four hermetic bags, two metallic bins, and two gunny bag (also known as jute or burlap bag) piles each containing 1 tonne of wheat were instrumented with temperature, relative humidity, and carbon dioxide sensors. Representative samples from each structure were collected each month and tests for moisture, germination, insect-damaged grain, and milling yield were performed. After nine months, wheat stored in hermetic bags had higher germination (87%) and lower insect-damaged grain percentages (0% to 0.33% with a mean value of 0.2%). Hermetic bags with deliberately introduced Rhyzopertha dominica successfully eliminated the …

Assessing The Archaeoparasitological Potential Of Quids As A Source Material For Immunodiagnostic Analyses, Johnica J. Morrow, Karl Reinhard

Karl Reinhard Publications

In the present study, quids from La Cueva de los Muertos Chiquitos (CMC) were subjected to ELISA tests for 2 protozoan parasites, Toxoplasma gondii (n=45) and Trypanosoma cruzi (n=43). The people who occupied CMC, the Loma San Gabriel, lived throughout much of present-day Durango and Zacatecas in Mexico. The known pathoecology of these people puts them into at-risk categories for the transmission of T. gondii and T. cruzi. Human antibodies created in response to these 2 parasites can be detected in modern saliva using ELISA kits intended for use with human serum. For these reasons, quids were reconstituted and …

Cardiorespiratory Fitness Is Associated With Better Executive Function In Young Women, Samuel P. Scott, Mary Jane De Souza, Karsten Koehler, Dylan L. Petkus, Laura E. Murray-Kolb

Department of Nutrition and Health Sciences: Faculty Publications

Purpose: A positive association between cardiorespiratory fitness (CRF) and cognitive function has been demonstrated mainly in children and older adults. Women attending college live in a cognitively demanding setting where optimal cognition matters but often experience declines in CRF. Our aim was to test whether CRF is associated with executive function in young adult women.

Methods: Participants in this cross-sectional study included 120 healthy women age 18–35 yr in a university setting. Each woman completed a maximal treadmill-based exercise test to determine peak oxygen uptake (V˙O_2peak), computerized tests of executive function, and questionnaires to assess motivation …

Fungi In The Healthy Human Gastrointestinal Tract, Heather E. Hallen-Adams, Mallory J. Suhr

Department of Food Science and Technology: Faculty Publications

Many species of fungi have been detected in the healthy human gut; however, nearly half of all taxa reported have only been found in one sample or one study. Fungi capable of growing in and colonizing the gut are limited to a small number of species, mostly Candida yeasts and yeasts in the family Dipodascaceae (Galactomyces, Geotrichum, Saprochaete). Malassezia and the filamentous fungus Cladosporium are potential colonizers; more work is needed to clarify their role. Other commonly-detected fungi come from the diet or environment but either cannot or do not colonize (Penicillium and Debaryomyces species, which are …

Eicosapentaenoic Acid Potentiates Brown Thermogenesis Through Ffar4-Dependent Up-Regulation Of Mir-30b And Mir-378*, Jiyoung Kim, Meshail Okla, Anjeza Erickson, Timothy P. Carr, Sathish Kumar Natarajan, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Emerging evidence suggests that n-3 polyunsaturated fatty acids (PUFA) promote brown adipose tissue thermogenesis. However, the underlying mechanisms remain elusive. Here, we hypothesize that n-3 PUFA promotes brown adipogenesis by modulating miRNAs. To test this hypothesis, murine brown preadipocytes were induced to differentiate the fatty acids of palmitic, oleate, or eicosapentaenoic acid (EPA). The increases of brown-specific signature genes and oxygen consumption rate by EPA were concurrent with up-regulation of miR-30b and 378 but not by oleate or palmitic acid. Next, we hypothesize that free fatty acid receptor 4 (Ffar4), a functional receptor for n-3 PUFA, modulates …

Structural Diversity In The Type Iv Pili Of Multidrug-Resistant Acinetobacter, Kurt H. Piepenbrink, Erik Lillehoj, Christian M. Harding, Jason W. Labonte, Xiaotong Zuo, Chelsea A. Rapp, Robert S. Munson Jr, Simeon E. Goldblum, Mario F. Feldman, Jeffrey J. Gray, Eric J. Sundberg

Food for Health: Publications

Acinetobacter baumannii is a Gram-negative coccobacillus found primarily in hospital settings that has recently emerged as a source of hospital-acquired infections. A. baumannii expresses a variety of virulence factors, including type IV pili, bacterial extracellular appendages often essential for attachment to host cells. Here, we report the high resolution structures of the major pilin subunit, PilA, from three Acinetobacter strains, demonstrating thatA. baumannii subsets produce morphologically distinct type IV pilin glycoproteins. We examine the consequences of this heterogeneity for protein folding and assembly as well as host-cell adhesion by Acinetobacter. Comparisons of genomic and structural data with pilin proteins from …

School of Natural Resources: Faculty Publications

The Napo Basin in Ecuador is an important drainage of the Amazon Basin, the most biodiverse ecosystem for freshwater species. At the same time, this basin has conspicuous information gaps on its biodiversity patterns and human threats. Here, we estimated the diversity distribution patterns of freshwater vertebrates and invertebrates in the Napo Basin, as a tool for present and future management and conservation efforts. Also, we assessed the spatial congruence of the diversity patterns observed between aquatic vertebrates and invertebrates. For this, we compiled occurrence records for 481 freshwater vertebrate species (amphibians, birds, mammals, reptiles, and fish), and 54 invertebrate …

Population Characteristics Of Human-Commensal Rodents Present In Households From Mérida, Yucatán, México, Jesús Alonso Panti-May, Silvia F. Hernández-Betancourt, Marco A. Torres-Castro, Carlos Machaín-Williams, Nohemi Cigarroa-Toledo, Lorenzo Sodá, Gabriela López-Manzanero, Josué R. Meza-Sulú, Victor M. Vidal-Martínez

MANTER: Journal of Parasite Biodiversity

Anthropocommensal rodents live in close proximity to humans in many habitats around the world. They are a threat to public health because of the pathogens they carry. Recent studies in Mérida, Yucatán, México, have shown that commensal rodents harbor potential zoonotic pathogens such as bacteria, helminths, and viruses. In this study, we describe reproductive and demographic parameters of house mice and black rats present in households from Mérida, Yucatán, México, a municipality located in a tropical region in southern México. Rodents were trapped in 142 households within the municipality of Mérida from 2011 to 2014. A total of 832 rodents …

Neuraminidase-1 (NEU1) is the predominant sialidase expressed in human airway epithelia and lung microvascular endothelia where it mediates multiple biological processes. We tested whether the NEU1-selective sialidase inhibitor, C9-butyl-amide-2-deoxy-2,3-dehydro-Nacetylneuraminic acid (C9-BA-DANA), inhibits one or more established NEU1-mediated bioactivities in human lung cells. We established the IC50 values of C9-BA-DANA for total sialidase activity in human airway epithelia, lung microvascular endothelia and lung fibroblasts to be 3.74 µM, 13.0 µM and 4.82 µM, respectively. In human airway epithelia, C9-BA-DANA dose-dependently inhibited flagellin-induced, NEU1-mediated mucin-1 ectodomain desialylation, adhesiveness for Pseudomonas aeruginosa and shedding. In lung microvascular endothelia, C9-BA-DANA reversed NEU1-driven restraint of …

Network Approaches To Substance Use And Hiv/Hepatitis C Risk Among Homeless Youth And Adult Women In The United States: A Review, Kirk Dombrowski, Kelley J. Sittner, Devan Crawford, Melissa L. Welch-Lazoritz, Patrick Habecker, Bilal Khan

Department of Sociology: Faculty Publications

During the United States economic recession of 2008–2011, the number of homeless and unstably housed people in the United States increased considerably. Homeless adult women and unaccompanied homeless youth make up the most marginal segments of this population. Because homeless individuals are a hard to reach population, research into these marginal groups has traditionally been a challenge for researchers interested in substance abuse and mental health. Network analysis techniques and research strategies offer means for dealing with traditional challenges such as missing sampling frames, variation in definitions of homelessness and study inclusion criteria, and enumeration/population estimation procedures. This review focuses …

Sub-Lethal Effects Of Dietary Neonicotinoid Insecticide Exposure On Honey Bee Queen Fecundity And Colony Development, Judy Wu-Smart, Marla Spivak

Department of Entomology: Faculty Publications

Many factors can negatively affect honey bee (Apis mellifera L.) health including the pervasive use of systemic neonicotinoid insecticides. Through direct consumption of contaminated nectar and pollen from treated plants, neonicotinoids can affect foraging, learning, and memory in worker bees. Less well studied are the potential effects of neonicotinoids on queen bees, which may be exposed indirectly through trophallaxis, or food-sharing. To assess effects on queen productivity, small colonies of different sizes (1500, 3000, and 7000 bees) were fed imidacloprid (0, 10, 20, 50, and 100 ppb) in syrup for three weeks. We found adverse effects of imidacloprid on queens …

The Islamic Foundation of Lincoln is a growing population within Lincoln including many different racial backgrounds, ethnic identities, and languages. Due to these various backgrounds communication may impair the education of families as well as their attitudes and behaviors. Although there are programs developed for many other minority groups, the Muslim (population comprising the Islamic Foundation of Lincoln) population does not have any data obtained from the community in terms of nutrition and physical activity behaviors, attitudes, and knowledge. This study seeks to understand if there are barriers to communication and if the intervention enhanced nutrition knowledge. This poster reflects …

Ex-Post Livestock Diseases, And Pastoralists' Averting Decisions In Tanzania, Mazbahul Ahamad

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Little is known about the factors affecting pastoralists’ livestock vaccination decisions. In this thesis, we use a novel survey-based dataset on pastoralists living in the Ruaha landscape in Tanzania, and employ several econometric approaches to identify the factors affecting pastoralists’ decision-making process about livestock vaccination when disease occurrence and severity, vaccination and healthcare access costs and other related variables are known. Results from binary choice models that account for excess zeros indicate that socially and economically active households are more likely to vaccinate their livestock. The results also identify positive marginal effects of illness incidence and having wage earners and …

Influence Of Resource Availability On Juniperus Virginiana Expansion In A Forest–Prairie Ecotone, A. C. Ganguli, D. M. Engle, P. M. Mayer, L. F. Salo

United States Environmental Protection Agency: Publications

Woody plant expansion into grasslands and savannas is a global concern. Rapid expansion of Juniperus virginiana, a tree native to North America, has profound ecological consequences. We used transplanted J. virginiana seedlings to investigate the role of resource availability on J. virginiana expansion following the removal of fire, the factor historically limiting range expansion of this fire-intolerant species. We evaluated J. virginiana seedling survival and seedling growth, two important phases in woody plant expansion, relative to two below ground resource factors, plant-available soil water (soil clay content, an index of plant-available soil water) and plant-available nitrogen (PAN), and an above …
