Do Oaks With A Provenance Related To Warmer Climates Emit More Isoprene?, 2015 DePaul University
Do Oaks With A Provenance Related To Warmer Climates Emit More Isoprene?, Elizabeth Carter
The hydrocarbon isoprene plays an important role in atmospheric chemistry, particularly in regards to air pollution and climate change. It is important to know why certain plant species emit isoprene and what factors affect its production in order to predict future air quality. Past research has indicated that isoprene aids in coping with heat stress, so it was hypothesized that source latitude (a proxy for climate) would significantly impact isoprene production by oaks grown in a common location. Twelve bur oaks collected from a latitudinal range (30-45˚) and raised at the Morton Arboretum were assayed for their isoprene emission rate ...
Predictive Modeling Of Oxygen Transmission Through Micro-Perforations For Packaging Applications, 2015 University of Florida
Predictive Modeling Of Oxygen Transmission Through Micro-Perforations For Packaging Applications, Ayman Abdellatief, Bruce A. Welt, Jason Butler, Eric Mclamore, Arthur Teixeira, Sanjay Shukla
Journal of Applied Packaging Research
Methods for creating precise perforations in respiring produce packaging are being increasingly adopted. Knowledge of oxygen transfer through perforated packaging and oxygen distribution in packages is necessary for successful packaging design of fresh produce. An approach to modeling perforated packaging performance was developed using a cylindrical chamber with precision perforations using Fick’s second law. The model was simulated using two techniques including Finite Element Method (FEM) using commercially available software and Finite Volume Method (FVM) through programming. Perforations were approximated as a source term in the second method. Both simulation techniques showed trends similar to experimental data.

Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, 2015 Fordham University
Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, Richard Ramsundar
Student Theses 2015-Present
This thesis compares and explains the advantages aquaponics farming has over modern industrial intensive farming. Through a comparison natural capital usage, conservation, recycling and cost, the thesis advocates for the expansion of aquaponics usage in urban settings. The thesis also explains the history of intensive farming and aquaponics in America, the science of how aquaponics operates, the economic and environmental costs of modern intensive farming versus aquaponics farming, and the social implications of aquaponics. Lastly, I propose a policy that reallocates farm subsidies by modifying the Farm Bill. Then I propose policies that support creating a new standard of farm ...

Biology Faculty Publications
In legumes, the formation of rhizobial and mycorrhizal root symbioses is a highly regulated process which requires close communication between plant and microorganism. Plant mutants that have difficulties establishing symbioses are valuable tools for unravelling the mechanisms by which these symbioses are formed and regulated. Here E151, a mutant of Pisum sativum cv. Sparkle, was examined to characterize its root growth and symbiotic defects. The symbioses in terms of colonization intensity, functionality of micro-symbionts, and organ dominance were compared between the mutant and wild type. The endogenous cytokinin (CK) and abscisic acid (ABA) levels and the effect of the exogenous ...

Characterization Of A Novel Clade Of Transporters In Phytophthora, Stephanie Padula, Paul F. Morris Dr, Howard Casey Cromwell Dr., Menaka Ariyaratne, Andrew Wagner
The oomycete Phytophthora parasitica has a worldwide distribution and is an economically important pathogen of more than 100 species4. RNA-seq analysis showed that one gene, PPTG_16698 has the 5th highest level of expression of all transport proteins in the zoospore stage, and is highly conserved throughout Phytophthora species. This project attempts to characterize the important biological role that PPTG_16698 plays in P. parasitica and other oomycetes. Three strategies have been implemented to accomplish this goal: growth analysis by heterologous expression in yeast, metabolite analysis in yeast, and construction of a GFP fusion protein to enable localization of the ...
Seasonal Activity And Sampling Methods For The Dectes Stem Borer, Dectes Texanus Leconte, In Nebraska Soybeans, 2015 University of Nebraska-Lincoln
Seasonal Activity And Sampling Methods For The Dectes Stem Borer, Dectes Texanus Leconte, In Nebraska Soybeans, Zachary D. Rystrom
Dissertations and Student Research in Entomology
The Dectes stem borer, Dectes texanus Leconte, has caused significant economic damage to soybean fields in south central Nebraska during recent years. Most economic injury occurs when soybean plants become susceptible to late season lodging due to larval girdling. Developing a comprehensive management plan for Dectes stem borer in Nebraska is limited by lack of knowledge of seasonal activity and effective sampling plans to monitor adult populations. Field studies were conducted in 2013 and 2014 to describe Dectes stem borer adult emergence patterns, female ovipositional period and adult densities in soybean fields. Calendar date predictions for adult emergence varied, while ...
Propagation Methods For Growing Spartina Alterniflora For Salt Marsh Restoration, 2015 University of Rhode Island
Propagation Methods For Growing Spartina Alterniflora For Salt Marsh Restoration, Samantha Walker
Senior Honors Projects
Salt marsh ecosystems can be found along the east coast of the United States, but are now disappearing due to human development and sea level rise. Salt marshes provide countless ecosystem services including shoreline protection from storms and flooding, nutrient removal, habitat for fish, birds and other wildlife, and provide some of the most beautiful areas for hunting, fishing and recreational activities. In order to protect salt marshes and restore the large portion of them that have been damaged, it is important to focus on the vegetation that help salt marshes function. Spartina alterniflora, smooth cordgrass, is a critical component ...
Plant Diversity Affects Performance Of Invasive Thistles In Restored Nebraska Grasslands, 2015 University of Nebraska-Lincoln
Plant Diversity Affects Performance Of Invasive Thistles In Restored Nebraska Grasslands, Katilyn J. Price
Dissertations & Theses in Natural Resources
Invasive plant species threaten native grasslands, affecting nutrient cycling, biodiversity, wildlife habitat, and usable land for production. Consequently, preventing establishment of invasive species is critical before removal becomes difficult and expensive. The purpose of this study was to examine the effects of grassland plant diversity on musk thistle (Carduus nutans) and Canada thistle (Cirsium arvense) establishment and determine which environmental factors (light penetration, soil moisture, plant diversity, and soil nitrogen) account for resistance to invasions. In a field experiment at The Nature Conservancy’s Wood River site (Nebraska), the two invasive thistle species were planted into replicated grassland diversity plots ...
Accessing Chilling Conditions For Perennial Fruit Crop Production In Kentucky, 2015 Western Kentucky University
Accessing Chilling Conditions For Perennial Fruit Crop Production In Kentucky, Yao Xue
Masters Theses & Specialist Projects
Temperate Region fruit and nut trees, and many other perennial plants, require cool winter temperatures (chilling hours) to ensure leaf and flower bud production in the following season. Temperate Regions are characterized by variable winter and spring temperatures. Failure of meeting sufficient chilling requirement results in deformed fruits, unequal maturation, and other plant deformities, thereby reducing quality and yields. Chilling requirements are expressed as number of accumulated hours within a range of approximately 32º to 45ºF or 0º to 7.2ºC. These requirements are specific for level of temperature, length of temperature period, and species and cultivar of plants. Information ...

Water quality of streams, rivers, and lakes is a critical environmental health issue and must be protected in order to prevent pollution. Watershed-‐based plans are one way to define and address current and potential water quality issues within a given watershed. This watershed-‐based plan will take a detailed look at the Georges Creek watershed. This subwatershed located within the Upper Saluda River Basin has sites listed on the South Carolina Department of Health and Environmental Control (SC DHEC) 303(d) and Total Maximum Daily Load (TMDL) lists, making it a prime location to evaluate. The watershed-‐based plan ...
Forest Sustainability In An Altered Landscape Requires Human Intervention, 2015 BUFFALO STATE COLLEGE
Forest Sustainability In An Altered Landscape Requires Human Intervention, Adam C. Labatore
Recruitment success determines the abundance and composition of plant communities. Successful recruitment can be summarized as a simple dichotomy of establishment versus seed limitations. Establishment limitation occurs when plant populations are inhibited by habitat availability and quality, whereas seed limitation occurs when seeds fail to arrive in necessary densities. Recruitment failure undermines overstory sustainability if the existing trees cannot replace themselves. Preliminary analysis indicated tree recruitment failure at an urban nature preserve with too few tree seedlings to replace mature canopy trees. These data suggested that the urban forest was not sustainable. The overarching goal of the study was to ...
Impact Of Arbuscular Mycorrhizal Fungi On The Physiology Of Maize Genotypes Under Variable Nitrogen And Phosphorus Levels, 2015 University of Nebraska-Lincoln
Impact Of Arbuscular Mycorrhizal Fungi On The Physiology Of Maize Genotypes Under Variable Nitrogen And Phosphorus Levels, Roberto Crespo
Theses, Dissertations, and Student Research in Agronomy and Horticulture
It is important to increase our understanding of AM fungal and maize genotype interactions, the impact of N and P fertilization and water condition on the symbiosis, and on the physiology and nutritional status of maize plants. In two greenhouse experiments AM inoculated plants exhibited root colonization values around 70% which was confirmed by the presence of the AM lipid biomarker (C16:1cis11). Nitrogen fertilization increased AM root colonization, but only compared to unfertilized plants. Root colonization and biomarker concentration in root and soil were similar among inoculated maize genotypes across conventional and drought tolerant hybrids. Mycorrhizal inoculation had a ...

Producing Quality Barley For The Malting Industry, Haley H. Oser Dph
Doctoral Documents from Doctor of Plant Health Program
The University of Nebraska – Lincoln Doctor of Plant Health program requires each student to fulfill a professional internship over the last summer of the program. For my internship, I worked as a Barley Scientist Intern for MillerCoors and Golden Malting in Golden, Colorado. During this internship I gained a fundamental understanding of malting barley production with a significant emphasis on grain quality. Barley produced for malting must fulfill strict industry quality standards before it is accepted by the head maltsters. These quality standards include: a high germination rate, low moisture content, protein content within an acceptable range and the grain ...
