Altered Collective Mitochondrial Dynamics In The Arabidopsis Msh1 Mutant Compromising Organelle Dna Maintenance, Joanna M. Chustecki, Ross D. Etherington, Daniel J. Gibbs, Iain G. Johnston

Department of Biochemistry: Faculty Publications

Mitochondria form highly dynamic populations in the cells of plants (and almost all eukaryotes). The characteristics and benefits of this collective behaviour, and how it is influenced by nuclear features, remain to be fully elucidated. Here, we use a recently developed quantitative approach to reveal and analyse the physical and collective ‘social’ dynamics of mitochondria in an Arabidopsis msh1 mutant where the organelle DNA maintenance machinery is compromised. We use a newly created line combining the msh1 mutant with mitochondrially targeted green fluorescent protein (GFP), and characterize mitochondrial dynamics with a combination of single-cell time-lapse microscopy, computational tracking, and network …

Integrating Biodiversity Content: Iczn -> Zoobank -> Institutional Repository -> Internet Archive, Sue Ann Gardner, Paul Royster

University of Nebraska-Lincoln Libraries: Presentations

Background

With rapidly advancing global warming and the concomitant disruptive effects on life on Earth, documenting species is urgent (Ceballos et al., 2020). Taxonomists are keenly aware that they must do all that they can to document species before their demise. As of 2012, the International Commission on Zoological Nomenclature (ICZN, 1999; 2012) began to allow electronic publication of nomenclatural acts (resulting in the official naming of animal species).

Problem

Even though 10 years have passed since changes to the codification regarding the registration of animal species names, repository managers and animal taxonomists may not be collaborating to their fullest …

Valuing Angling On Reservoirs Using Benefit Transfer, Richard T. Melstrom, Mark A. Kaemingk, Nicholas W. Cole, John C. Whitehead, Christopher J. Chizinski, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Economic assessments are rarely applied to inland recreational fisheries for management purposes, especially when compared to fish, habitat, and creel assessments, yet economic assessments can provide critical information for management decisions. We provide a brief overview of economic value, key terminology, and existing economic techniques to address these issues. Benefit transfer, a technique used to measure economic value when an original analysis is not practicable, is conducted by drawing on existing estimates of economic value in similar contexts. We describe an application of benefit transfer to measure the economic value of several recreational fisheries in Nebraska, USA. We examine two …

Bridging The Gap Between Research And Smallholder Farmers Through Community-Based Development Organizations, Nathan D. Fortner

Doctor of Plant Health Program: Dissertations and Student Research

Food demand is expected to increase 30% to 62% by 2050 according to recent estimates. Yet, annual increases in agricultural productivity have slowed and plateaued since the green revolution increases of the 1960’s. Two strategies to help address future food demand are reducing post-harvest loss and consumer waste, and closing the yield gap between potential and farmer realized yields. Some of the largest yield gaps are those of smallholder farmers. While solutions may exist to close these gaps, delivering and integrating solutions into smallholder production systems is a complex process involving research, extension, cultural factors, government policy, NGOs, private industry, …

Balloons, Breadcrumbs, And Spoons: Emerging Adults’ Privacy Negotiation And Management Of The (Non)Disclosure Of Chronic Illness-Related Information With A Friend, Robert D. Hall

Department of Communication Studies: Dissertations, Theses, and Student Research

Emerging adults (EAs) experience many changes throughout this life-stage, characterized by self-focus, identity explorations, instability, in-betweenness, and possibilities of optimism (Arnett, 2014). As EAs transition from home of origin into independence, they may place more reliance on social networks apart from their family of origin (e.g., friends, Rawlins, 2009). Yet, chronically ill EAs may experience complications due to the biographical disruption, or interference of expectations in one’s life (Bury, 1982), particularly given that chronic illness is typically viewed as an elderly-related issue rather than occurring with youth (Kundrat & Nussbaum, 2003). Through transitions in the EA life-stage, EAs with chronic …

Recombination Hotspots In Soybean [Glycine Max (L.) Merr.], Samantha J. Mcconaughy

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

Recombination allows for the exchange of genetic material between two parents which plant breeders exploit to make new and improved varieties. This recombination is not distributed evenly across the chromosome. In crops, it mostly occurs in the euchromatic regions of the genome and even then, recombination is focused into recombination hotspots flanked by recombination cold spots. Understanding the distribution of these hotspots along with the sequence motifs associated with them may lead to methods that enable breeders to better exploit recombination in breeding.

In chapter 1 background information on recombination, recombination hotspots detection methods, landscape of recombination (describe recombination patterns …

Gender Role Congruence And Self-Efficacy In Emerging Outdoor Leaders, Audrey Krimm

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

Being a leader in the outdoors requires the competence and confidence to act and make decisions in high-risk situations. However, female leaders may experience an incongruence between the assertive decision-making expected of their leadership role and the passivity expected of their gender role, which can impact their leadership self- efficacy. The purpose of this study was to explore how gender role congruence influences the self-efficacy of male and female emerging outdoor leaders. A convergent mixed- methods design was used by triangulating self-efficacy survey data with in-depth interviews, observations, and reflective drawings from eight student outdoor leaders at a large Midwestern …

Rare Dark American Kestrel – Melanistic Or Sooty?, Joseph A. Gubanyi, Joel Rathe, Camden Sesna

Nebraska Bird Review

On April 13 in Seward County, we noticed a dark bird flying relatively low over fields east of Seward near 224th and Bluff Rd. Initially, because of its size, dark coloration and pointed wingtips, we were unsure of its identification and followed the bird to get better looks and identify it. We were able to observe and photograph the bird perched (Figure 1). We also observed the bird hovering and diving to the ground multiple times in search of prey. After better looks, based on size, wing shape, hooked beak, claws, and behavior (repeated hovering over field), we concluded the …

Wynn, Grace Capshaw, Matthew L. Niemiller, John G. Phillips, Jeremy F. Jacobs, Shawn R. Kuchta, Rayna C. Bell

United States Geological Survey: Staff Publications

Due to their limited geographic distributions and specialized ecologies, cave species are often highly endemic and can be especially vulnerable to habitat degradation within and surrounding the cave systems they inhabit. We investigated the evolutionary history of the West Virginia Spring Salamander (Gyrinophilus subterraneus), estimated the population trend from historic and current survey data, and assessed the current potential for water quality threats to the cave habitat. Our genomic data (mtDNA sequence and ddRADseq-derived SNPs) reveal two, distinct evolutionary lineages within General Davis Cave corresponding to G. subterraneus and its widely distributed sister species, Gyrinophilus porphyriticus, that …

Toxicological Responses To Sublethal Anticoagulant Rodenticide Exposure In Free‑Flying Hawks, Nimish B. Vyas, Barnett A. Rattner, J. Michael Lockhart, Craig S. Hulse, Clifford P. Rice, Frank Kuncir, Kevin Kritz

United States Geological Survey: Staff Publications

An important component of assessing the hazards of anticoagulant rodenticides to non-target wildlife is observations in exposed free-ranging individuals. The objective of this study was to determine whether environmentally realistic, sublethal first-generation anticoagulant rodenticide (FGAR) exposures via prey can result in direct or indirect adverse effects to free-flying raptors. We offered black-tailed prairie dogs (Cynomys ludovicianus) that had fed on Rozol® Prairie Dog Bait (Rozol, 0.005% active ingredient chlorophacinone, CPN) to six wild-caught red-tailed hawks (RTHA, Buteo jamaicensis), and also offered black-tailed prairie dogs that were not exposed to Rozol to another two wild-caught RTHAs for 7 …

In both courses, a PBL pedagogy was implemented such that students were self-learning and discovering the knowledge through an action-research case study. The action-research case study was specific to the course outcomes relevant …

Within‑Marsh And Landscape Features Structure Ribbed Mussel Distribution In Georgia, Usa, Marshes, William K. Annis, Elizabeth A. Hunter, John M. Carroll

United States Geological Survey: Staff Publications

Ribbed mussels, Geukensia demissa, are marsh fauna that are used in coastal management and restoration due to the ecosystem services they provide. Ribbed mussel restoration efforts may be improved with a greater understanding of the environmental drivers of ribbed mussel distribution at multiple spatial scales to predict areas where restoration could be successful. This study sought to estimate the effects of within-marsh (4 m) and landscape (500 m) factors on ribbed mussel distribution. Ribbed mussel densities were surveyed at 11 sites along the coast of Georgia, USA, and overlaid with spatial data for within-marsh factors (elevation, distance to marsh …

Jenkins, Kristopher M. Kusnerik, Ashley W. Poust, Selina V. Robson, Judith A. Sclafani, Kelsey T. Stilson, Shamindri D. Tennakoon, Carmi Milagros Thompson

School of Biological Sciences: Faculty Publications

As practitioners of a historical science, paleontologists and geoscientists are well versed in the idea that the ability to understand and to anticipate the future relies upon our collective knowledge of the past. Despite this understanding, the fundamental role that the history of paleontology and the geosciences plays in shaping the structure and culture of our disciplines is seldom recognized and therefore not acted upon sufficiently. Here, we present a brief review of the history of paleontology and geology in Western countries, with a particular focus on North America since the 1800s. Western paleontology and geology are intertwined with systematic …

Rosasco, Emily A. Melchior-Tiffany, Cierrah J. Kassetas, Shad H. Cox, Richard L. Dunlap, Jennifer A. Hernandez Gifford, Eric J. Scholljegerdes, Robert A. Cushman, Adam F. Summers

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Management strategies utilized during pre-breeding development of replacement heifers can impact fertility and the ovarian reserve. Angus- Hereford crossbred heifers (n = 233) were utilized over a 3-yr period to determine the effects of administration of a growth promoting implant at either branding or weaning on growth, reproduction, and ovarian development. Heifer calves were randomly assigned to one of three treatments: 1) nonimplanted controls (CON; n = 79), 2) implanted at approximately 2 mo of age (average calf age = 58 d) with Synovex-C (BIMP, n = 82), or 3) implanted at approximately 7 mo of age (average calf …

Guard-Cell-Targeted Overexpression Of Arabidopsis Hexokinase 1 Can Improve Water Use Efficiency In Field-Grown Tobacco Plants, Liana G. Acevedo-Siaca, Katarzyna Glowacka, Steven M. Driever, Coralie E. Salesse-Smith, Nitsan Lugassi, David Granot, Stephen P. Long, Johannes Kromdijk

Department of Biochemistry: Faculty Publications

Water deficit currently acts as one of the largest limiting factors for agricultural productivity worldwide. Additionally, limitation by water scarcity is projected to continue in the future with the further onset of effects of global climate change. As a result, it is critical to develop or breed for crops that have increased water use efficiency and that are more capable of coping with water scarce conditions. However, increased intrinsic water use efficiency (iWUE) typically brings a trade-off with CO₂ assimilation as all gas exchange is mediated by stomata, through which CO₂ enters the leaf while water vapor exits. …

Towards A Cybersecurity Testbed For Agricultural Vehicles And Environments, Mark Freyhof, George Grispos, Santosh Pitla, Cody Stolle

Department of Agricultural and Biological Systems Engineering: Faculty Publications

In today’s modern farm, an increasing number of agricultural systems and vehicles are connected to the Internet. While the benefits of networked agricultural machinery are attractive, this technological shift is also creating an environment that is conducive to cyberattacks. While previous research has focused on general cybersecurity concerns in the farming and agricultural industries, minimal research has focused on techniques for identifying security vulnerabilities within actual agricultural systems that could be exploited by cybercriminals. Hence, this paper presents STAVE – a Security Testbed for Agricultural Vehicles and Environments – as a potential solution to assist with the identification of cybersecurity …

Nutrient Restoration Of A Large, Impounded, Ultra-Oligotrophic Western River To Recover Declining Native Fishes, Ryan S. Hardy, Tyler J. Ross, Kevin N. Mcdonnell, Michael C. Quist, Charlie Holderman, Bryan S. Stevens

United States Geological Survey: Staff Publications

Declines in many fish populations in large, western rivers have been primarily attributed to the anthropogenic reduction of nutrient inputs and subsequent impacts to the food web. The largest known river fertilization program was implemented starting in 2005 on the Kootenai River in northern Idaho to restore resident fisheries. Annual electrofishing surveys were conducted at multiple sites in Idaho and Montana before and during nutrient addition to evaluate assemblage and population-level responses. Although few responses in fish assemblage structure were observed, the addition of liquid ammonium polyphosphate fertilizer (3 μg/L) to the Kootenai River increased fish abundance and biomass over …
