Production, Persistence And Diversity Of Species In Temperate Grasslands, Meredith L. Mitchell, Brendan P. Christy

IGC Proceedings (1977-2023)

Temperate grassland areas are considered to be semi-arid, with rainfall typically between 250 and 500 mm, much of it occurring in the late spring and early summer. Grazing plays an important role in all these grasslands with impacts on diversity and persistence. Against this assumption that seasonal productivity would be more uniform within a pasture that was diverse, the research suggested that species rich pastures were less stable, because this species richness was composed of non-perennial, volunteer and weed species. This paper explores the concept that systems diversity of temperate grassland does not always equate to production. In these systems …

Using Various Lactic Acid Bacteria Strains During Forage Conservation Towards Fermentation, Storage, Nutritive Value And Safety Improvement, Jonas Jatkauskas, Vilma Vrotniakiene

IGC Proceedings (1977-2023)

Many research efforts have been devoted to find ways how to produce silages with maximum nutritive value, good fermentation and low mould and yeast counts. While there are different objectives in using silage additives, the main objectives are to improve fermentation and reduce dry matter loss, and to prevent secondary fermentation at feed out time. This paper presents our most significant and recent investigations on forage inoculation before ensiling that have a potential for beneficial application on grassland and ruminant nutrition.

Traditional Livestock Production And Growth Opportunities In India, S. M. Deb

IGC Proceedings (1977-2023)

Livestock and animal health development projects need to be based on an understanding of livestock production systems because different systems need different approaches particularly in view of degradation of environment combined with population pressure. In India, the livestock production system is primarily traditional, consisting of mixed-farming and pastoral systems, therefore, development of marginal and smallholder mixed farms must aim at intensification of the total production system. Resource-poor farming systems may aim at the improved management of the various livestock species in backyards. Pastoral systems must focus on effective management of grazing pressure. Community pasture management involves application of technologies, land …

Nutrient Movements Through Ruminant Livestock Production Systems, Adegbola T. Adesogan, Jose C. B. Dubeux, Lynn E. Sollenberger

IGC Proceedings (1977-2023)

Considerable attention has been paid to reducing nutrient emissions from ruminant livestock in the last few decades. This area will continue to attract considerable research in the future due to increasing farm sizes in some developed countries as well as the increasing demand for meat and dairy products, particularly in developing countries. This paper discusses the deposition and losses of carbon and nitrogen in soils and plants in grazed and harvested forage systems as well as utilization and losses of both nutrients by ruminants in both systems. The paper also outlines several soil, plant, and animal-focused strategies that can be …

Strengthening Livelihood Of Rural Farmer Populations Through Improved Grasslands, Sujatha Premaratne, S. C. Somasiri

IGC Proceedings (1977-2023)

This paper reviews the current background of the grassland resource with a purpose of livestock perspective to improve the livelihood of rural farmers. The use of grasslands for livestock rearing by rural farmers has been a long tradition. In climate and vegetation contrast, these grasslands are much more diverse. They are likely to play an economical role in increasing the milk production in many Asian countries. With an increase of human population, the traditional feeding, breeding and surviving habitats for livestock have been acutely restricted in many countries. Therefore, a continued effort is needed to maintain production for sustainable management …

Livestock And Local Development: Going To A New Humananimal Relationship, Jean François Tourrand, Laurent Dobremez, Benoit Dedieu, Guillaume Duteurtre, M. G. Piketty, P. Lescoat, B. Hubert

IGC Proceedings (1977-2023)

Along the past ten years, the French National Agency for Research (ANR) has financed projects regarding livestock. Results of five projects were gathered to understand the long-term livestock trends. At the end of the 19th century, animal breeding was oriented towards the production of goods to meet the local, regional, national and global demand, according to the zone. The market gradually became the key-factor to norm both production and consumption. It is now integrating environmental norms and is starting to invest in the social domain. However, this economical vision of animal production does not take into account the other functions …

Emission Of Green House Gases From Grasslands And Their Mitigation, Prem N. Sharma, Shyam Khadka

IGC Proceedings (1977-2023)

The concentrations of green house gases (GHG) in the atmosphere began in pre-industrial times and it continues to increase. This could result into an alarming increase in temperature of up to 5.4 ^oC by year 2100 due to a net global annual GHG emission of H 4.5-6.5 Gt C equivalent. About 18% of the world’s GHG are contributed by livestock and related activities on grasslands that are spread over almost 35 million Km².These grasslands give livelihood to over a billion people most of who are poor. Twenty to 70% of the land surface area is degrading often …

Physiological Function Of Fus: An Rna Binding Protein In Motor Neuron Disease, Liuqing Yang

Theses and Dissertations--Molecular and Cellular Biochemistry

FUS is an RNA binding protein implicated in the motor neuron disease— amyotrophic lateral sclerosis (ALS, also called Lou Gehrig’s disease). ALS is a fatal neurodegenerative disease characterized by progressive motor neuron death. Mutations in the FUS gene cause about 4% of familial ALS (FUS ALS). Mutated FUS protein mislocalizes from the motor neuron nucleus to the cytoplasm and forms inclusions in the cytoplasm. It is unclear how FUS mislocalization induces motor neuron dysfunction and degeneration. This dissertation research was designed to investigate the physiological functions of FUS in the nucleus, with a purpose to shed light on the pathogenesis …

Dual Functions For Insulinoma-Associated 1 In Retinal Development, Marie A. Forbes-Osborne

Theses and Dissertations--Biology

Proper visual system function requires tightly controlled proliferation of a pool of relatively homogeneous retinal progenitor cells, followed by the stepwise specification and differentiation of multiple distinct cell types. These retinal cells, both neuronal and glial, must be generated in the correct numbers, and the correct laminar location to permit the formation of synaptic connections between individual cell types. After synapses are made, constant signaling is required as part of normal retinal function, and to maintain cellular identity and connectivity. These processes rely on both extrinsic and intrinsic signaling, with regulation of gene expression by cascades of transcription factors having …

Animal And Pasture Responses To Grazing Management Of Chemically Suppressed Tall Fescue In Mixed Pastures, Jessica A. Williamson

Theses and Dissertations--Plant and Soil Sciences

Treatment of endophyte-infected tall fescue [Lolium arundinaceum (Schreb.) Darbysh] with the broad leaf herbicide Chaparral® can mitigate fescue toxicosis and enhance forage quality by suppressing seedhead emergence. Applying the herbicide to fescue pastures also reduces forage mass and promotes severe spot grazing when pastures are continuously grazed. A grazing experiment was conducted with steers (2013) and heifers (2014) to evaluate animal and plant responses in fescue-bluegrass (Poa pratensis L.) mixtures treated with Chaparral to determine the effects of grazing management on pasture carrying capacity, nutritive values, botanical composition, and animal performance. Continuous and rotational (i.e., four subdivisions to …

Examining Vegetative Growth Of Cool-Season Forage Grasses For Dairy Cattle Grazing Preference, Eric D. Billman

Theses and Dissertations--Plant and Soil Sciences

The objective of this study was to determine dairy cattle preference amongst four species of cool-season forage grasses: eight orchardgrasses (Dactylis glomerata L.), five tall fescues [Schedonorus arundinaceus (Schreb.) Dumort.], five perennial ryegrasses (Lolium perenne L.), and six festuloliums [xFestulolium braunii (K. Richt.) A. Camus.]; 24 cultivars in total. Each grazing trial utilized four Holstein-Friesian heifers over six hours. Maturity differences were eliminated by having animals graze only vegetative material. After six grazing trials (three each in 2014 and 2015), consistent results in animal preference were not found; three of the six trials did show preference …

Hypertension Health Behavior Change And Older Adults: The Effect Of An Appreciative Education Approach, Mary Katherine Benya

Theses and Dissertations

Making lifestyle changes has been found to be effective in controlling hypertension. Positive psychology may provide alternatives to existing health behavior change approaches. Appreciative Education (AE), a positive psychology approach, was applied to an existing hypertension control intervention, Lifestyle University (LU), and compared to the Social Cognitive Theory (SCT) approach, in a segment of the existing intervention. This study used quasi-experimental, mixed methods pre/post-test, repeated measures design. Two-groups of community-dwelling adults, aged 50+, control SCT (n= 60), and experimental AE (n=33), were compared using the LU intervention. Seven dependent variables were measured at pre-test, post-test 1 and post-test 2. Repeated …

Dissolved And Particulate Phosphorus Distributions And Elemental Stoichiometry Throughout The Chukchi Sea, Meryssa Piper

Theses and Dissertations

As the only gateway of material, particularly nutrients, from the Pacific to the Arctic Ocean, the biological and chemical transformations that occur within the Chukchi Sea are critical for understanding Arctic ecosystems. This study examines the biogeochemical cycling of the macronutrient phosphorus (P) relative to carbon and nitrogen in the eastern Chukchi Sea during the ICESCAPE’s mission. Sea ice and water column dissolved and particulate phosphorus samples were collected during two summer expeditions in 2010 (n=593) and 2011 (n=989). Despite being a landlocked marginal sea, the P pool present within the Chukchi Sea was substantially modified by biological processes with …

Patient And Provider Characteristics And Practice Patterns Of Primary Care Physicians Of Weight-Related Counseling, Kolby T. Redd

Theses and Dissertations

Background: The United States Preventive Services Task Force (USPSTF) recommends three types of health education counseling for use in primary care practices for adult, obese patients. While these recommendations are well known, a low percentage of physicians provide this counseling to their patients on a consistent basis. There are inconsistencies in past studies in regards to what aspects of the health encounter influence the likelihood of receiving health education counseling during a primary care visit. The objective of this study was to (1) investigate the patterns of these three types of counseling occurring within primary care practices and to …

Factors Contributing To Interannual Variability In The Abundance Of Bay Anchovy (Anchoa Mitchilli) Larvae, Steven B. Vega Jr.

Theses and Dissertations

Coastal ecosystems have been subject to increasing stressors over recent decades due to coastal development, human population growth, and climate change. Improving scientific understanding of the environmental factors which influence the productivity of fish populations in coastal ecosystems is vital to their prudent management, especially as the potential influence of anthropogenic climate change grows. Estuaries serve as critical habitats for many fishes of primary ecological, economic, and recreational importance. One such fish, the planktivorous Bay Anchovy (Anchoa mitchilli), is abundant along the Atlantic and Gulf coasts of the US and is a key prey resource for many estuarine and coastal …

Developmental Biology And Effects Of Adult Diet On Consumption, Longevity, And Fecundity Of Colaspis Crinicornis (Coleoptera: Chrysomelidae), Kentaro Miwa, Lance Meinke

Department of Entomology: Faculty Publications

The chrysomelid beetle Colaspis crinicornis Schaeffer (Coleoptera: Chrysomelidae) occurs primarily in the Great Plains region of the United States. Little is known about the biology and ecology of this species, but over the last decade, it has become increasingly common in the corn, Zea mays L., and soybean, Glycine max (L.) Merrill, agroecosystem of southeastern Nebraska. As part of a larger comprehensive project to understand the natural history and pest potential of this species, laboratory experiments were conducted to study the developmental biology, morphological characters of immature stages, and the effect of adult diet on consumption, longevity, and fecundity. Females …

Ethylene Contributes To Maize Insect Resistance1-Mediated Maize Defense Against The Phloem Sap-Sucking Corn Leaf Aphid, Joe Louis, Saumik Basu, Suresh Varsani, Lina Castano-Duque, Victoria Jiang, W. Paul Williams, Gary W. Felton, Dawn S. Luthe

Department of Entomology: Faculty Publications

Signaling networks among multiple phytohormones fine-tune plant defense responses to insect herbivore attack. Previously, it was reported that the synergistic combination of ethylene (ET) and jasmonic acid (JA) was required for accumulation of the maize insect resistance1 (mir1) gene product, a cysteine (Cys) proteinase that is a key defensive protein against chewing insect pests in maize (Zea mays). However, this study suggests that mir1-mediated resistance to corn leaf aphid (CLA; Rhopalosiphum maidis), a phloem sap-sucking insect pest, is independent of JA but regulated by the ET-signaling pathway. Feeding by CLA triggers the rapid accumulation of mir1 transcripts in the resistant …

Department of Entomology: Faculty Publications

The western chinch bug, Blissus occiduus Barber, is a serious pest of buffalograss, Buchloe dactyloides (Nuttall) due to physical and chemical damage caused during the feeding process. Although previous work has investigated the feeding behaviors of chinch bugs in the Blissus complex, no study to date has explored salivary gland morphology and the associated salivary complex of this insect. Whole and sectioned B. occiduus salivary glands were visualized using light and scanning electron microscopy to determine overall structure and cell types of the salivary glands and their individual lobes. Microscopy revealed a pair of trilobed principal glands and a pair …

Transcriptional Responses Of Tolerant And Susceptible Soybeans To Soybean Aphid (Aphis Glycines Matsumura) Herbivory, Travis J. Prochaska, Teresa Donze-Reiner, L. Marchi-Werle, N. A. Palmer, Thomas E. Hunt, Gautam Sarath, Tiffany Heng-Moss

Department of Entomology: Faculty Publications

The soybean aphid, Aphis glycines Matsumura, was introduced in 2000 to North America and has become one of the most significant pests to soybean, Glycine max (L.) Merrill, production. Possible solutions to this problem are the use of resistant plants and the understanding of the genes involved in plant resistance. In this study, we sought to better understand the genes involved in the tolerance response of soybean plants to the soybean aphid, utilizing tolerant (KS4202) and susceptible (K-03-4686) plants. Studies were conducted under greenhouse conditions. Leaf samples of both tolerant and susceptible plants were collected at day 5 and day …

Planting Date And Variety Selection For Management Of Viruses Transmitted By The Wheat Curl Mite (Acari: Eriophyidae), Anthony J. Mcmechan, Gary Hein

Department of Entomology: Faculty Publications

Wheat is an important food grain worldwide, and it is the primary dryland crop in the western Great Plains. A complex of three viruses (Wheat streak mosaic, Wheat mosaic, and Triticum mosaic viruses) is a common cause of loss in winter wheat production in the Great Plains. All these viruses are transmitted by the wheat curl mite (Aceria tosichella Keifer). Once these viruses are established, there are no curative actions; therefore, prevention is the key to successful management. A study was designed to evaluate preventative management tactics (planting date, resistant varieties) for reducing the impact from this virus complex. …

On-Plant Larval Movement And Feeding Behavior Of Fall Armyworm (Lepidoptera: Noctuidae) On Reproductive Corn Stages, Luiz E. R. Pannuti, Edson L. L. Baldin, Thomas E. Hunt, Silvana L. Vieira De Paula Moraes

Department of Entomology: Faculty Publications

Spodoptera frugiperda J.E. Smith (fall armyworm) is considered one of the most destructive pests of corn throughout the Americas. Although this pest has been extensively studied, little is known about its larval movement and feeding behavior on reproductive compared to vegetative corn stages. Thus, we conducted studies with two corn stages (R₁ and R₃) and four corn plant zones (tassel, above ear, ear zone, and below ear) in the field at Concord, NE (USA), and in the field and greenhouse at Botucatu, SP (Brazil), to investigate on-plant larval movement. The effects of different corn tissues (opened tassel, …

Impact Of Spodoptera Frugiperda Neonate Pretreatment Conditions On Vip3aa19 Insecticidal Protein Activity And Laboratory Bioassay Variation, Karen F. Da Silva, Terence A. Spencer, Carolina Camargo Gil, Blair D. Siegfried, Frederick S. Walters

Department of Entomology: Faculty Publications

BACKGROUND: Variation in response to insecticidal proteins is common upon repetition of insect bioassays. Understanding this variation is a prerequisite to detecting biologically important differences.We tracked neonate Spodoptera frugiperda (J.E. Smith) susceptibility to Vip3Aa19 over 17 generations using standardized bioassay methods. Five larval pretreatment conditions and one bioassay condition were tested to determine whether susceptibility was affected. These included: storage time; prefeeding; storage at reduced temperature; storage at reduced humidity; colony introgression of field-collected individuals. Extremes of photoperiod during the bioassay itself were also examined.

RESULTS: LC₅₀ values for two strains of S. frugiperda varied 6.6-fold or 8.8-fold over …

Patterns Of Differential Gene Expression In Adult Rotation-Resistant And Wild-Type Western Corn Rootworm Digestive Tracts, Chia-Ching Chu, Jorge A. Zavala, Joseph L. Spencer, Matías J. Curzi, Christopher J. Fields, Jenny Drnevich, Blair D. Siegfried, Manfredo J. Seufferheld

Department of Entomology: Faculty Publications

The western corn rootworm (WCR, Diabrotica virgifera virgifera LeConte) is an important pest of corn. Annual crop rotation between corn and soybean disrupts the corn-dependent WCR life cycle and is widely adopted to manage this pest. This strategy selected for rotation-resistant (RR) WCR with reduced ovipositional fidelity to corn. Previous studies revealed that RR-WCR adults exhibit greater tolerance of soybean diets, different gut physiology, and host–microbe interactions compared to rotation-susceptible wild types (WT). To identify the genetic mechanisms underlying these phenotypic changes, a de novo assembly of the WCR adult gut transcriptome was constructed and used for RNA-sequencing analyses of …

Human Absorbable Microrna Prediction Based On An Ensemble Manifold Ranking Model, Jiang Shu, Kevin Chiang, Dongyu Zhao, Juan Cui

School of Computing: Faculty Publications

MicroRNAs, a class of short non-coding RNAs, are able to regulate more than half of human genes and affect many fundamental biological processes. It has been long considered synthesized endogenously until very recent discoveries showing that human can absorb exogenous microRNAs from dietary resources. This finding has raised a challenge scientific question: which exogenous microRNAs can be integrated into human circulation and possibly exert functions in human? Here we present a well-designed ensemble manifold ranking model for identifying human absorbable exogenous miRNAs from 14 common dietary species. Specifically, we have analyzed 4,910 dietary microRNAs with 1,120 features derived based on …

The Benefits And Risks Of Telling And Listening To Stories Of Difficulty Over Time: Experimentally Testing The Expressive Writing Paradigm In The Context Of Interpersonal Communication Between Friends, Jody Koenig Kellas, Haley Kranstuber Hortsman, Erin K. Willer, Kristen Carr

Department of Communication Studies: Faculty Publications

The overarching goal of the current study was to determine the impact of talking interpersonally over time on emerging adults’ individual and relational health. Using an expressive writing study design (see Frattaroli, 2006), we assessed the degree to which psychological health improved over time for college students who told and listened to stories about friends’ current difficulties in comparison with tellers in control conditions. We also investigated the effects on tellers’ and listeners’ perceptions of each other’s communication competence, communicated perspective taking, and the degree to which each threatened the other’s face during the interaction over time to better understand …

Salmonella Enterica Serovar Typhimurium-Infected Pigs With Different Shedding Levels Exhibit Distinct Clinical, Peripheral Cytokine And Transcriptomic Immune Response Phenotypes, Susan M. Knetter, Shawn M. D. Bearson, Ting-Hua Huang, Dason Kurkiewicz, Martine Schroyen, Dan Nettleton, Daniel Berman, Valerie Cohen, Joan K. Lunney, Amanda E. Ramer-Tait, Michael J. Wannemuehler, Christopher K. Tuggle

Foodborne salmonellosis costs the US $2.7 billion/year, including $100.0 million in annual losses to pork producers. Pigs colonized with Salmonella are usually asymptomatic with varied severity and duration of fecal shedding. Thus, understanding the responses that result in less shedding may provide a mechanism for control. Fifty-four pigs were inoculated with Salmonella enterica serovar Typhimurium (ST) and clinical signs, fecal ST shedding, growth performance, peripheral cytokines and whole blood gene expression were measured. Persistently shedding (PS) pigs had longer pyrexia and elevated serum IL-1b, TNF-a and IFN-g compared with low shedding (LS) pigs, while LS pigs had brief pyrexia, less …

Sourdough Lactic Acid Bacteria As Antifungal And Mycotoxin-Controlling Agents, Yousef I. Hassan, Ting Zhou, Lloyd B. Bullerman

Department of Food Science and Technology: Faculty Publications

Sourdough starter cultures are rich sources of endogenous lactic acid bacteria. The extended shelf lives of sourdough breads are attributed to a large array of organic acids and low-molecular-weight metabolites produced during the fermentation process. Different species belonging to the lactic acid bacteria group of microorganisms, mainly Lactobacillus and Leuconostoc, are increasingly gaining the attention as possible means for inhibiting mold growth in animal feed and human food chains. In addition, certain lactic acid bacteria strains isolated from sourdough starters were also shown to reduce mycotoxins concentrations in contaminated products either by binding or degradation. This short review will …
