Remembering Paul Johnsgard, Linda R, Brown, Josef Kren

Zea E-Books Collection

Paul A. Johnsgard (1931–2021) was a friend of many, an artist, prolific author, teacher, and humble admirer of all living creatures. It was impossible to find someone at Nebraska Audubon Society or Nebraska Ornithologists’ Union meetings who did not know Paul Johnsgard. His more than 100 published books made him known not just in a community of ornithologists, birdwatchers, and bird lovers in the United States but also abroad. He was a world-renowned ornithologist and naturalist who remained deeply embedded in his local culture and its prairie environment.

We invited about 75 people to write a short memory of Paul. …

Prairie Dogs, Gary Witmer, Jon Grant, Kendra Cross

Wildlife Damage Management Technical Series

Prairie dogs (Cynomys spp.) occur throughout the prairie states of middle North America from Mexico northward into Canada. They occupy a variety of habitats from prairies to high mountain valleys and sage brush-dominated deserts. The most common species is the black-tailed prairie dog (Cynomys ludovicianus; Figure 1). Prairie dogs are considered a “keystone species.” They provide habitat for many other native, grassland species. Prairie dogs live in colonies or “towns” that can span hundreds to thousands of acres. Depending on the species, their presence is evident by their burrow system. Despite the many ecosystem benefits prairie dogs provide by modifying …

Intensifying A Crop–Fallow System: Impacts On Soil Properties, Crop Yields, And Economics, S. J. Ruis, S. Stepanovic, Humberto Blanco-Canqui

Department of Agronomy and Horticulture: Faculty Publications

Intensifying crop–fallow systems could address increased weed control costs, increased land or rental costs, reduced crop diversity, and degraded soil properties in water-limited environments. One strategy to intensify such systems could be the insertion of a short-season crop during fallow. But, how this strategy affects soils, crop production, and farm economics needs further research. Thus, we studied the impacts of replacing fallow in a winter wheat (Triticum aestivum L)–corn (Zea mays L.)–fallow system with a short-season spring crop [field pea (Pisum sativum L.)] on crop yields and economics from 2015 to 2019 and 5-yr cumulative effects on …

Metabolic Network Modeling To Unravel The Impact Of Copper Deficiency And High-Fat Diet On Liver Metabolism, Naeun Lee

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Fatty liver disease is a common health problem caused by an imbalance in the intake, utilization, and distribution of energy. High-fat and high-carbohydrate diets have been identified as major risk factors for fatty liver disease. Other contributors and modifiers can also influence the development of liver damage. Intriguingly, inappropriate copper (Cu) levels in the diet and organs are associated with fatty liver disease, though the exact way in which Cu deficiency or toxicity contributes to metabolic issues is not yet clear. Cu is necessary for several biological processes, including energy production and redox balance. Further research should be taken to …

Assessing Functional Biodiversity For The Future Of Plants, Planet, And People, Ali Loker

Doctor of Plant Health Program: Dissertations and Student Research

Biodiversity plays a critical role in supporting life in global ecosystems and its links to ecosystem services and sustainability are recognized by scientific and non-scientific communities. Growing awareness of the importance of biodiversity is accelerated by discussions of its loss, and how to design interventions to conserve and mitigate a biodiversity crisis. Stakeholders are funding and implementing assessment strategies at various scales to help direct conservation efforts. There is also growing interest in measuring and communicating biodiversity outcomes.

Functional biodiversity characterizes the multiplicity of life forms into groups based on their diverse contributions to natural and agro-ecosystems. Assessing functional biodiversity …

The Impact Of Parent Math Anxiety On Parent Homework Help Behaviors, Makenzie P. Starlin

Honors Program: Senior Projects (Public)

Math anxiety is commonly defined as negative feelings toward mathematics or solving mathematics problems (Dowker et al., 2016). Research indicates that math anxiety can influence parenting behaviors during homework interactions, which can involve behaviors that are autonomy supportive, or allow the child to initiate the homework task, or controlling, which does not allow the child to be actively engaged (Retanal et al., 2021) In particular, autonomy support behaviors allow children to work through homework on their own, whereas control behaviors do not allow children to work through the homework on their own and instead involve parents overseeing the homework help …

All Bark And No Byte: A Case Study On Nuclear Weapons' Role In Cyber Deterrence, Phuc Nguyen

Honors Program: Senior Projects (Public)

In what some scholars consider a marked departure from its traditional policy, the U.S.' 2018 Nuclear Deterrence Posture Review declared that the U.S. would consider the use of nuclear weapons in response to "significant, non-nuclear strategic attacks." However, despite real-world examples of the type of significant cyberattacks on U.S., allied, or partner civilian population or infrastructure alluded to in the Review, the factors that might trigger multidomain escalation remain underexplored, which creates a credibility gap in the U.S.' deterrence policy. This paper explores these factors by providing a case study of the North Korean WannaCry and Russian NotPetya cyberattacks and …

Systematic Review: Effect Of Cover Crop On Working Farm, Noella A. Bahatsi

Honors Program: Senior Projects (Public)

On-farm research is when research techniques such as randomized, replicated treatments strips and large-scale techniques are used on actual farms or ranches. Due to a great deal of interest and curiosity among farmers and researchers who wish to make their farming methods more profitable, efficient, and/or sustainable, this type of research has been conducted more frequently each year. On-farm research has contributed to economic growth and the transfer of knowledge to farmers because of fresh discoveries and upgraded technology (Lacoste et al., 2022). This is also where farmers collaborate with researchers to test new management practices and technologies providing unbiased …

Climate And Pest Interactions Pose A Cross-Landscape Management Challenge To Soil And Water Conservation, Joshua W. Campbell, Michael R. Fulcher, Brenda J. Grewell, Stephen L. Young

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Climate change and biological invasions by plant pests (weeds), agriculture and forest insect pests (insects), and microbial pests (plant pathogens) are complex interactive components of global environmental change. The influence of pest distribution and prevalence across landscapes are challenging the conservation and sustainability of natural resources, agricultural production, native biological diversity, and the valuable ecosystem services they provide (Huenneke 1997; Vitousek 1997; Juroszek and von Tiedemann 2013; Ziska and Dukes 2014). Since 2000, numerous scientific studies indicate accelerating climate change is posing substantial risks to natural and managed systems in North America (IPPC 2022). Intensified droughts, largescale wildfires, and increased …

Abnormal Ear Development In Corn: Does Hybrid, Environment, And Seeding Rate Matter?, Osler A. Ortez, Anthony J. Mcmechan, Emily Robinson, Thomas C. Hoegemeyer, Reka Howard, Roger W. Elmore

Department of Agronomy and Horticulture: Faculty Publications

Corn (Zea mays L.) yields have increased in the United States since the 1930s and in other parts of the world since the 1950s and 1960s because of improvements in agricultural management and genotypes. Despite these increases, production concerns still exist. In July 2016, abnormal ear development (multi-ears per node, barbell-ears, and short-husks) was reported in cornfields that extended from the Texas Panhandle to eastern Colorado and east through Kansas, Nebraska, Iowa, and Illinois. Surveys in Nebraska farmer fields revealed significant productivity losses due to the issues, but little was known about the underlying causes. A research study was …

Editorial: Structure And Function Of Chloroplasts, Volume Iii, Hongbo Gao, Alistair J. Mccormick, Rebecca Roston, Yan Lu

Department of Biochemistry: Faculty Publications

Chloroplasts are endosymbiotic organelles derived from cyanobacteria. They have a double envelope membrane, including the outer envelope and the inner envelope. A complex membrane system, thylakoids, exists inside the chloroplast. It is the site of the light-dependent reactions of photosynthesis. The stroma is the main site of the carbon fixation reactions. Although photosynthesis is a very complicated process with many proteins involved, there are many other important processes that occur in chloroplasts, including the regulation of photosynthesis, the biogenesis and maintenance of the structures, carbohydrate, lipid, tetrapyrrole, amino acid, and isoprenoid metabolism, production of some phytohormones, production of specialized metabolites, …

The Effect Of Relative Humidity On Eddy Covariance Latent Heat Flux Measurements And Its Implication For Partitioning Into Transpiration And Evaporation, Weijie Zhang, Martin Jung, Mirco Migliavacca, Rafael Poyatos, Diego G. Miralles, Tarek S. El-Madany, Marta Galvagno, Arnaud Carrara, Nicola Arriga, Andreas Ibrom, Ivan Mammarella, Dario Papale, Jamie R. Cleverly, Michael Liddell, Georg Wohlfahrt, Christian Markwitz, Matthias Mauder, Eugenie Paul-Limoges, Marius Schmidt, Sebastian Wolf, Christian Brümmer, M. Altaf Arain, Silvano Fares, Tomomichi Kato, Jonas Ardö, Walter Oechel, Chad Hanson, Mika Korkiakoski, Sébastien Biraud, Rainer Steinbrecher, Dave Billesbach, Leonardo Montagnani, William Woodgate, Changliang Shao, Nuno Carvalhais, Markus Reichstein, Jacob A. Nelson

Department of Agricultural and Biological Systems Engineering: Faculty Publications

While the eddy covariance (EC) technique is a well-established method for measuring water fluxes (i.e., evaporation or 'evapotranspiration’, ET), the measurement is susceptible to many uncertainties. One such issue is the potential underestimation of ET when relative humidity (RH) is high (>70%), due to low-pass filtering with some EC systems. Yet, this underestimation for different types of EC systems (e.g. open-path or closed-path sensors) has not been characterized for synthesis datasets such as the widely used FLUXNET2015 dataset. Here, we assess the RH-associated underestimation of latent heat fluxes (LE, or ET) from different EC systems for 163 sites in …

Two Qtls Govern The Resistance To Sclerotinia Minor In An Interspecific Peanut Ril Population, Melina H. Rosso, Francisco J. De Blas, Alicia N. Massa, Claudio Oddino, Damian F. Giordano, Jose G. Seijo, Renee S. Arias, Juan H. Soave, Sara J. Soave, Mario I. Buteler, Marina Bressano

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Sclerotinia blight is a soilborne disease caused by Sclerotinia minor Jagger and can produce severe decrease in yield. Cultural management strategies and chemical treatment are not completely effective; therefore, growing peanut-resistant varieties is likely to be the most effective control method for this disease. Sclerotinia blight resistance has been identified in wild Arachis species and further transferred to peanut elite cultivars. To identify the genome regions conferring Sclerotinia blight resistance within a tetraploid genetic background, this study evaluated a population of recombinant inbred lines (RIL) with introgressed genes from three wild diploid species: A. cardenasii, A. correntina, and A. batizocoi. …

Encouraging Or Guilt-Inducing? An Analysis Of Fitspiration Content And Its Effect On Body Image And Lifestyle Changes, Brenna Mazour

Honors Program: Senior Projects (Public)

More people are acquiring their nutrition and exercise information from social media accounts called fitspiration. Analyses of fitspiration content have found the focus to be on restrictive diets and excessive exercise that’s appearance driven. Although its intent is to inspire its consumers to change their lifestyle, many speculate that it brings upon negative body image and induces guilt. The Theory of Planned Behavior (TPB) has been used to determine why people take part in certain health behaviors, such as diets or exercise regimens posted on fitspiration. TPB shows how the characteristics of social media discourage people to use fitspiration as …

Association Of IsvSa3 With Multidrug Resistance In Salmonella Enterica Isolates From Cattle (Bos Taurus), Gentry L. Lewis, Robert J. Fenton, Etsuko Moriyama, John Dustin Loy, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Salmonella enterica is, globally, an important cause of human illness with beef being a significant attributable source. In the human patient, systemic Salmonella infection requires antibiotic therapy, and when strains are multidrug resistant (MDR), no effective treatment may be available. MDR in bacteria is often associated with the presence of mobile genetic elements (MGE) that mediate horizontal spread of antimicrobial resistance (AMR) genes. In this study, we sought to determine the potential relationship of MDR in bovine Salmonella isolates with MGE. The present study involved 111 bovine Salmonella isolates obtained collectively from specimens derived from healthy cattle or their environments …

Multifunctional Microgel-Based Cream Hydrogels For Postoperative Abdominal Adhesion Prevention, Bo Liu, Yunfan Kong, Olawale A. Alimi, Mitchell Kuss, Huiyin Tu, Wenfeng Hu, Abu Rafay, Kumar Vikas, Wen Shi, Megan Lerner, William L. Berry, Yulong Li, Mark A. Carlson, Bin Duan

Department of Mechanical and Materials Engineering: Faculty Publications

Postoperative abdominal adhesions are a common problem after surgery and can produce serious complications. Current anti-adhesive strategies focus mostly on physical barriers and are unsatisfactory and inefficient. In this study, we designed and synthesized advanced injectable cream-like hydrogels with multiple functionalities, including rapid gelation, self-healing, anti-oxidation, anti-inflammation, and anti-cellular adhesion. The multifunctional hydrogels were facilely formed by the conjugation reaction of epigallocatechin gallate (EGCG) and hyaluronic acid (HA)-based microgels and polyvinyl alcohol (PVA) based on the dynamic boronic ester bond. The physicochemical properties of the hydrogels including anti-oxidative and anti-inflammatory activities were systematically characterized. A mouse cecum-abdominal wall adhesion model …

Assessment Of Ring-Tailed Lemur Lemur Catta Populations In South-Western Madagascar, Sylvain Randrianjaka, Samantha Calkins, Timothy M. Sefczek, Cynthia L. Frasier, Richard Randriamampionona, Jean Claude Rakotoniaina, Lily-Arison R. De Roland, Andrea L. Baden, Edward E. Louis Jr.

School of Global Integrative Studies: Faculty Publications

Anthropogenic activities are negatively affecting the flora and fauna of Madagascar, including its Endangered flagship lemur species, the ring-tailed lemur Lemur catta. Population numbers at some sites are rapidly declining, yet much of the species’ habitat is insufficiently surveyed. Because widespread population assessments are critical to guiding conservation management strategies, additional data are needed to monitor L. catta population trends and to identify the limits of their geographical range. Here we report survey results confirming the presence of this species at 65 of 83 sites in southern and south-western Madagascar, including three subpopulations that were previously considered likely to …

Evaluating Metabolic And Genomic Data For Predicting Grain Traits Under High Night Temperature Stress In Rice, Ye Bi, Rafael Massahiro Yassue, Puneet Paul, Balpreet Kaur Dhatt, Jaspreet Sandhu, Phuc Thi Do, Harkamal Walia, Toshihiro Obata, Gota Morota

Department of Agronomy and Horticulture: Faculty Publications

The asymmetric increase in average nighttime temperatures relative to increase in average daytime temperatures due to climate change is decreasing grain yield and quality in rice. Therefore, a better genome-level understanding of the impact of higher night temperature stress on the weight of individual grains is essential for future development of more resilient rice. We investigated the utility of metabolites obtained from grains to classify high night temperature (HNT) conditions of genotypes, and metabolites and single-nucleotide polymorphisms (SNPs) to predict grain length, width, and perimeter phenotypes using a rice diversity panel. We found that the metabolic profiles of rice genotypes …

Viscoelastic Properties Of Human Facial Skin And Comparisons With Facial Prosthetic Elastomers, Mark W. Beatty, Alvin G. Wee, D. B. Marx, Lauren Ridgway, Bobby Simetich, Thiago Carvalho De Sousa, Kevin Vakilzadian, Joel Schulte

Department of Statistics: Faculty Publications

Prosthesis discomfort and a lack of skin-like quality is a source of patient dissatisfaction with facial prostheses. To engineer skin-like replacements, knowledge of the differences between facial skin properties and those for prosthetic materials is essential. This project measured six viscoelastic properties (percent laxity, stiffness, elastic deformation, creep, absorbed energy, and percent elasticity) at six facial locations with a suction device in a human adult population equally stratified for age, sex, and race. The same properties were measured for eight facial prosthetic elastomers currently available for clinical usage. The results showed that the prosthetic materials were 1.8 to 6.4 times …

Sphingolipid Long-Chain Base Signaling In Compatible And Non-Compatible Plant–Pathogen Interactions In Arabidopsis, Mariana Saucedo-García, Ariadna González-Solís, Priscila Rodríguez-Mejía, Guadalupe Lozano-Rosas, Teresa De Jesús Olivera-Flores, Laura Carmona-Salazar, A. Arturo Guevara-García, Edgar B. Cahoon, Marina Gavilanes-Ruíz

Center for Plant Science Innovation: Faculty Publications

The chemical diversity of sphingolipids in plants allows the assignment of specific roles to special molecular species. These roles include NaCl receptors for glycosylinositolphosphoceramides or second messengers for long-chain bases (LCBs), free or in their acylated forms. Such signaling function has been associated with plant immunity, with an apparent connection to mitogen-activated protein kinase 6 (MPK6) and reactive oxygen species (ROS). This work used in planta assays with mutants and fumonisin B1 (FB1) to generate varying levels of endogenous sphingolipids. This was complemented with in planta pathogenicity tests using virulent and avirulent Pseudomonas syringae strains. Our results indicate that the …

Effect Of Osmotic Potential And Temperature On Germination Of Kochia (Bassia Scoparia) Populations From The U.S. Great Plains, Ramawatar Yadav, Prashant Jha, Andrew R. Kniss, Nevin C. Lawrence, Gustavo M. Sbatella

Panhandle Research and Extension Center

Development of integrated weed management strategies requires knowledge of weed emergence timing and patterns, which are regulated primarily by water and thermal requirements for seed germination. Laboratory experiments were conducted in fall 2017 to fall 2018 to quantify the effect of osmotic potential and temperature on germination of 44 kochia [Bassia scoparia (L.) A.J. Scott] populations under controlled conditions. Bassia scoparia populations were collected in fall 2016 from northern (near Huntley, MT, and Powell, WY) and southern (near Lingle, WY, and Scottsbluff, NE) regions of the U.S. Great Plains. Ten osmotic potentials from 0 to −2.1 MPa and eight …

Alfalfa In Rotation With Annual Crops Reduced Nitrate Leaching Potential, Arshdeep Singh, Tahseen Afzal, Bryan Woodbury, Charles Wortmann, Javed Iqbal

Department of Agronomy and Horticulture: Faculty Publications

Rotation of perennial alfalfa (Medicago sativa L.) with annual crops has the potential to reduce nitrate-nitrogen (NO₃-N) in the vadose zone and increase soil organic carbon (SOC) sequestration. The objective of this study was to determine the long-term effects on SOC, NO₃-N, ammonium-N (NH₄-N), and soil water in the 7.2 m depth with an alfalfa rotation compared with continuous corn (Zea mays L.). Soils from six pairs of alfalfa rotation versus continuous corn observation points were sampled to 7.2 m depth in 0.3 m increments. The uppermost 0.3 m was divided into …

How Administration Stakes And Settings Affect Student Behavior And Performance On A Biology Concept Assessment, Crystal Uminski, Joanna K. Hubbard, Brian A. Couch

School of Biological Sciences: Faculty Publications

Biology instructors use concept assessments in their courses to gauge student understanding of important disciplinary ideas. Instructors can choose to administer concept assessments based on participation (i.e., lower stakes) or the correctness of responses (i.e., higher stakes), and students can complete the assessment in an in-class or out-of-class setting. Different administration conditions may affect how students engage with and perform on concept assessments, thus influencing how instructors should interpret the resulting scores. Building on a validity framework, we collected data from 1578 undergraduate students over 5 years under five different administration conditions. We did not find significant differences in scores …

Soybean Seed Protein Concentration Is Limited By Nitrogen Supply In Tropical And Subtropical Environments In Brazil, E. H. Figueiredo Moura Da Silva, N. Cafaro La Menza, G. G. Munareto, A. J. Zanon, Santos Carvalho, F. R. Marin

Department of Agronomy and Horticulture: Faculty Publications

Soybean production contributes to ca. 60% of global plant-based protein used for food and feed. Brazil is the largest soybean producer and exporter, with 60% from tropical and 40% from subtropical environments. Nitrogen (N) can play an essential role in the storage of proteins in seeds; thus, it could be a key factor in increasing the quantity and quality of seeds in high-yielding soybean crops. Unlike in temperate environments, there is a gap of knowledge on whether soybean grown under tropical and subtropical climates are limited by N-fertilization to sustain the seed yield increase without detriments in seed protein concentration. …

Population Dynamics And Harvest Management Of Eastern Mallards, Anthony J. Roberts, Jeffrey A. Hostetler, Joshua C. Stiller, Patrick K. Devers, William A. Link

United States Fish and Wildlife Service: Publications

Managing sustainable harvest of wildlife populations requires regular collection of demographic data and robust estimates of demographic parameters. Estimates can then be used to develop a harvest strategy to guide decision‐making. Mallards (Anas platyrhynchos) are an important species in the Atlantic Flyway for many users and they exhibited exponential growth in the eastern United States between the 1970s and 1990s. Since then, estimates of mallard abundance have declined 16%, prompting the Atlantic Flyway Council and United States Fish and Wildlife Service to implement more restrictive hunting regulations and develop a new harvest strategy predicated on an updated population …
