Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Recreational fisheries (RF) are complex social-ecological systems that play an important role in aquatic environments while generating significant social and economic benefits around the world. The nature of RF is diverse and rapidly evolving, including the participants, their priorities and behaviors, and the related ecological impacts and social and economic benefits. RF can lead to negative ecological impacts, particularly through overexploitation of fish populations and spread of non-native species and genotypes through stocking. Hence, careful management and monitoring of RF is essential to sustain these ecologically and socioeconomically important resources. This special issue on recreational fisheries contains diverse research, syntheses ...

Maternal N-3 Polyunsaturated Fatty Acids Supplementation Potentiates Brown Adipose Tissue Development And Reduces The Risk Of Childhood Obesity, Rong Fan Dec 2018

Maternal N-3 Polyunsaturated Fatty Acids Supplementation Potentiates Brown Adipose Tissue Development And Reduces The Risk Of Childhood Obesity, Rong Fan

Nutrition & Health Sciences Dissertations & Theses

Brown adipose tissue (BAT) is a crucial regulator in energy expenditure by dissipating energy in the form of heat through mitochondrial uncoupling protein 1 (UCP1). Previously, we demonstrated that n-3 PUFA (Omega-3 Polyunsaturated Fatty Acids) increase brown adipogenesis by miRNA-mediated epigenetic mechanisms. Given that BAT is formed at the late stage of pregnancy, we hypothesized prenatal exposure of n-3 PUFA through maternal nutrition potentiates BAT development. To test this hypothesis, Female C57BL/6 mice were fed a diet containing n-3 PUFA (3%) derived from fish oil (FO), or an isocaloric diet devoid of n-3 PUFA (Cont), and same diet was ...

Studies On The Physicochemical Characterization Of Flours And Protein Hydrolysates From Common Beans, Hollman Andres Motta Romero Nov 2018

Studies On The Physicochemical Characterization Of Flours And Protein Hydrolysates From Common Beans, Hollman Andres Motta Romero

Dissertations, Theses, & Student Research in Food Science and Technology

Pulses represent a rich source of nutrition and have several potential health benefits such as the reduction of the risk of developing cardiovascular diseases, obesity, and diabetes. Beans from the species Phaseolus vulgaris and Cicer arietinum are important crops raised in some regions of the United States, including Western Nebraska. Nevertheless, the traditional preparation procedures involved in the cooking of these beans are tedious and time-consuming, thus leading to the underutilization of these resources. Therefore, the present work focused on evaluating alternative utilizations of these beans in order to improve their economic value.

One alternative to improve the consumption of ...


Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen Nov 2018

Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen

Dissertations & Theses in Natural Resources

The use of artificial nests to study the predation of avian nests has faced disregard by ecologists due to inconsistencies found between the survival rates of real and artificial nests across studies and reviews. The negative perception of artificial nests providing an inconsistent assessment of survival has thus fostered the perception that artificial nests are a secondary option to be used to overcome logistical hurdles associated with achieving sufficient sample sizes in systems where study species are rare or elusive, or as merely a preliminary method to study predation across gradients. We argue that the greatest mistake ecologists have made ...

Xanthomonas vasicola pv. vasculorum, causal agent of bacterial leaf streak of corn, was first reported in the U.S. in 2016 on Nebraska corn leaf samples. Prior to this report, the pathogen had only been reported on corn in South Africa. After the Nebraska report, the pathogen was reported on corn in Argentina, Brazil, and several U.S. states. This pathogen has an extensive host range, which includes sugarcane (Saccharum officinarum), grain sorghum (Sorghum bicolor), palm species (Dictyosperma album, Roystonea regia, and Areca catechu) and broom bamboo (Thysanolaena maxima). Plants commonly found in the U.S. had not been evaluated ...


Biological Activity Of A Tertiary Amine Plant Growth Regulator, Bmve, In Arabidopsis Thaliana And Wheat (Triticum Aestivum), Jaspinder Singh Nov 2018

Biological Activity Of A Tertiary Amine Plant Growth Regulator, Bmve, In Arabidopsis Thaliana And Wheat (Triticum Aestivum), Jaspinder Singh

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Plant growth regulators are synthetic compounds that influence plant growth and development and can increase growth, yield, and nutritive value of food crops. Research in the past has shown that a class of plant growth regulators known collectively as substituted tertiary amines have the potential to increase crop productivity, photosynthetic efficiency, and overall plant vigor. However, earlier efficacy studies that involved spraying plants were sometimes inconsistent or showed only minimal benefits. A new delivery method involving seed application of tertiary amines before sowing has shown promise in field trials for multiple crop species (US patent 9464283) (Yokoyama, Chan, Oyama, & Hov ...

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

Natural history collections spanning multiple decades provide fundamental historical baselines to measure and understand changing biodiversity. New technologies such as next generation DNA sequencing have considerably increased the potential of museum specimens to address significant questions regarding the impact of environmental changes on host and parasite/pathogen dynamics. We developed a new technique to identify intestinal helminth parasites and applied it to shrews (Eulipotyphla: Soricidae) because they are ubiquitous, occupy diverse habitats, and host a diverse and abundant parasite fauna. Notably, we included museum specimens preserved in various ways to explore the efficacy of using metabarcoding analyses that may enable ...


Initiative 427: Nebraska Medicaid Expansion, J. David Aiken Oct 2018

Initiative 427: Nebraska Medicaid Expansion, J. David Aiken

Cornhusker Economics

This article summarizes information regarding Initiative 427–the Medicaid expansion question on the November 6, 2018 ballot. It reprints the actual ballot language and the Nebraska Secretary of State’s summary of arguments for and against Initiative 427.

Background. Originally Medicaid covered the elderly, the disabled, children in low-income families, and low-income pregnant women. In 2010 Medicaid coverage was expanded by Congress to include the working poor. In 2012 the U.S. Supreme Court ruled that the provision of the Affordable Care Act (ACA) requiring states to expand Medicaid was unconstitutional. This made it a state option whether or not ...

Farm Programs, Payments And Prospects Oct 2018

Farm Programs, Payments And Prospects

Cornhusker Economics

The USDA Farm Service Agency (FSA) began issuing payments to producers in October for Price Loss Coverage (PLC) and Agriculture Risk Coverage (ARC) programs for the 2017 crop year. While these farm program payments had provided substantial cash flow to help buffer falling market price and farm income projections in the past three years, the current programs will provide relatively little cash flow for now and for the coming year. Only the ad hoc trade assistance payments and the outlook for new farm programs and decisions in 2019 may provide potential relief from the current outlook.

Agronomy & Horticulture -- Faculty Publications

Sorghum (Sorghum bicolor) is a drought tolerant crop, which is being developed as a bioenergy feedstock. The monolignol biosynthesis pathway is a major focus for altering the abundance and composition of lignin. Caffeoyl coenzyme-A O-methyltransferase (CCoAOMT) is an S-adenosyl methionine (SAM)-dependent O-methyltransferase that methylates caffeoyl-CoA to generate feruloyl-CoA, an intermediate required for the biosynthesis of both G- and S-lignin. SbCCoAOMT was overexpressed to assess the impact of increasing the amount of this enzyme on biomass composition. SbCCoAOMT overexpression increased both soluble and cell wall-bound (esterified) ferulic and sinapic acids, however lignin concentration and its composition (S ...
