Growth Of Black Walnut In Southeast Nebraska, Benjamin A. Loseke, Dennis M. Adams

Nebraska Forest Service: Publications

Black walnut (Juglans nigra L.), within the family Juglandaceae, is a premier hardwood timber species in the United States. Its native range encompasses most of the eastern U.S., roughly extending from eastern South Dakota and eastern Texas on its western edge to Massachusetts and western Florida in the east (Figure 1). The occurrence and productivity of black walnut on the western edge of its native range, including eastern Nebraska, is largely a function of available water during the growing season. However, black walnut has been extensively planted west and north of its native range. Studies have shown black walnut can …

A Quantitative Analysis Of The Effect Of Cash-4-Grass Programs On Water Consumption, Cynthia Allen

Walden Dissertations and Doctoral Studies

Water supplies in California are stretched to critical levels as a result of population growth, periodic drought, and climate change. The California legislature recognized that the best way to increase supply is to decrease demand so the Water Use Efficiency Senate Bill 7 (SBx7-7) was signed into law in 2009. The law requires water purveyors to reduce per capita water usage by 20% by the year 2020. To comply, water purveyors are searching for innovative ways to increase water conservation. A review of the literature has shown that many factors influence water consumption. However, the majority of household water consumption …

Encouraging Teacher Change Within The Realities Of School-Based Agricultural Education: Lessons From Teachers’ Initial Use Of Socioscientific Issues-Based Instruction, Amie Wilcox, Catherine W. Shoulders, Brian E. Myers

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Calls for increased interdisciplinary education have led to the development of numerous teaching techniques designed to help teachers provide meaningful experiences for their students. However, methods of guiding teachers in the successful adoption of innovative teaching approaches are not firmly set. This qualitative study sought to better understand how school-based agricultural education teachers decide to adopt or discontinue a teaching innovation when introduced through ready-made lesson plans, which is currently a common practice of teaching method integration in school-based agricultural education (SBAE). Constant comparative analysis unveiled themes within the reactions to the teaching method’s use, as well as how teacher …

Earthquake Risk In Indonesia: Parametric Contingent Claims For Humanitarian Response And Financial Institution Resiliency, Jason Hartell

Theses and Dissertations--Agricultural Economics

This dissertation explores the use of an index based contingent claims mechanism against earthquake risk in Indonesia. It focuses on time critical financing needs of international humanitarian relief organizations, and on efforts to improve the resiliency of geographically constrained financial institutions whose clientele are exposed to disaster risk. The approach uses measures of ground motion intensity as the basis for the index. The humanitarian response mechanism provides a new way for private sector partners to participate and gain visibility in their support of principled humanitarian funding. Index based contingent claims for local banks are shown to enhance their ability to …

Effects Of Sodium Hydroxide Pretreatment On Structural Components Of Biomass, Alicia A. Modenbach, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

Pretreatment is a unit operation in the conversion of biomass to valuable products that utilizes various combinations of conditions, including chemicals, heat, pressure, and time, to reduce the recalcitrance of lignocellulose. Many such pretreatments have been developed over the years, as the operating conditions can be adapted so that lignocellulose is modified in ways unique to each pretreatment. By tailoring pretreatment conditions to achieve these modifications, the types of final products produced can be controlled. The purpose of this review is to provide a consolidated source of information for sodium hydroxide effects on lignocellulose. The structural characteristics of lignocellulose and …

Effectiveness Of A Farm Field Trip, Bonnie S. Sigmon

Theses and Dissertations--Community & Leadership Development

The annual Sigmon Farm Tour was started in 1992 as an agricultural education program where students could experience being on a farm with the goal of increasing the agricultural literacy levels of the participants. Every year the entire 4th grade student population of Rockcastle County spends the day touring the farm and participating in experiential mini lessons given by the cooperating farm service and health agencies. The program has continued for 20+ years without an evaluation as to whether it is achieving its objectives. This evaluation will also exhibit the programs strengths and weakness so it can continue to improve. …

The Role Of The Bacterial Endosymbiont, Arsenophonus, In The Soybean Aphid, Aphis Glycines, Jason A. Wulff

Theses and Dissertations--Entomology

Bacterial endosymbionts can have profound impacts on their host’s ecology. Notably, endosymbionts can protect their hosts against natural enemies and influence host plant interactions. The endosymbiont Candidatus Arsenophonus infects a wide taxonomic range of arthropod hosts, and is suspected of an uncharacterized mutualistic role in hemipterous insects. In the soybean aphid, Aphis glycines, an introduced pest of soybeans in the United States, Arsenophonus is the sole facultative endosymbiont. The focus of this dissertation is to characterize the role of Arsenophonus in the aphid, with an overall emphasis on its impact on aphid management strategies.

I first used diagnostic PCR …

Changing Litter Resources Associated With Hemlock Woolly Adelgid Invasion Affect Benthic Communities In Headwater Streams, Christopher J. Strohm

Theses and Dissertations--Entomology

Hemlock woolly adelgid is an invasive herbivore causing extensive mortality of eastern hemlock, an important foundation species that provides stable conditions influencing biological communities. Hemlock is often found in riparian areas and following its decline, broadleaved species, including birch, beech, and rhododendron, will replace it. These plants differ from hemlock in patterns of canopy cover and leaf properties, which influence conditions and resources within streams.

My goal was to evaluate potential impacts of adelgid-induced alterations to riparian canopies and litter on benthic communities and litter breakdown in streams. I characterized benthic invertebrate communities, litter colonization and litter breakdown in streams …

Assessing And Mitigating Lawn Insecticide Hazards To Bees And Other Beneficial Invertebrates, Jonathan Lane Larson

Theses and Dissertations--Entomology

Turfgrass settings, including lawns, golf courses, and sports fields, support many beneficial invertebrates that provide important ecosystem services. These non-target organisms and their associated predation, decomposition, and pollination services can be disrupted by the use of certain insecticides. I compared the ecotoxicity of representatives from three major turf insecticide groups, the neonicotinoids, premix formulations, and the anthranilic diamides, in lab and field realistic settings in order to inform industry initiatives towards environmental sustainability.

In lab and field bioassays clothianidin, a neonicotinoid, and a premix clothianidin/pyrethroid spray were acutely toxic to beneficial insects. Populations of predators, springtails, and earthworms, as well …
