Sensitivity Of Marine Cynobacteria And Green Microlage To Nano And Bulk Zinc Oxides, Jennifer Gil-Acevedo 3664585

FIU Electronic Theses and Dissertations

Nanoparticles are particles with sizes between 1 and 100 nanometers (nm). Owing to their unique chemical, electrical, mechanical, optical, and piezoelectric properties, zinc oxide nanoparticles (ZnO-NPs) are finding widespread use in numerous applications with yearly production over 550 tons per year. Increasing use of ZnO NPs, and NPs in wastewater discharges from domestic and industrial sources will have significant potential for adverse impacts on aquatic phototrophic organisms. Comparative studies on microalgae species response to ZnO NPs and variation in tolerance among species is still mostly unexplored. The proposed research aims to evaluate interspecies’ variation in tolerance to ZnO NPs among …

Farm Location Influence On The Optimal Crop Insurance And Pre-Harvest Hedging Level, Cory Walters

Cornhusker Economics

Improving farm financial health can come from improving the understanding of the market forces influencing the optimal crop insurance contract and preharvest hedging risk management tools. The biggest challenge for farmers is the difficulty of assessing risk since experiencing risk, is by default, rare. Additionally, farmers receive advice about which crop insurance plan they should purchase or how much pre-harvest hedging they should do from sources, such as farm magazines, that likely do not consider the differences in individual risk exposure. Following the advice of such sources could result in producers being inadvertently exposed to more risk. A producer’s location …

Growing A Sustainable City: The Question Of Urban Agriculture, Hamil Pearsall

Sustainability Seminar Series

This presentation examines urban agriculture in Philadelphia and highlights the challenges of institutionalizing this historically informal urban activity into formal city policy over the last two decades. Urban agriculture has become a symbol of Philadelphia’s economic revitalization, sustainability, and increasingly, its gentrification. Often characterized by advocates as an urban panacea, gardening and farming seem to promise solutions to many different urban problems, such as blighted vacant lots, food insecurity, stormwater runoff, and neighborhood decline. However, questions of land tenure, the use of economic resources, and the long-term viability of urban agriculture shape the political discourse about the future of growing …

Greenhouse Gas Emissions And Crop Yield In No-Tillage Systems: A Meta-Analysis, Yawen Huang, Wei Ren, Lixin Wang, Dafeng Hui, John H. Grove, Xiaojuan Yang, Bo Tao, Ben Goff

Biology Faculty Research

No-tillage (NT) has been touted as one of several climate-smart agriculture (CSA) management practices that improve food security and enhance agroecosystem resilience to climate change. However, the sustainable effectiveness of NT greatly depends on trade-offs between NT-induced changes in crop yield and greenhouse gas (GHG, i.e. CH4, CO2, and N2O) emissions. Such trade-offs are regulated by climate fluctuations and heterogeneous soil conditions and have not been well addressed. Supporting CSA management decisions requires advancing our understanding of how NT affects crop yield and GHG emissions in different agroecological regions. In this study, a meta-analysis was conducted using 740 paired measurements …

The Corn/Soybean Rotation And Profitability, Matt Stockton, Devin Broadhead

Cornhusker Economics

One of the most basic questions farmers must answer on an annual basis is what to plant. In some cases this is simply a choice among cultivars in others it is a choice among different crop types. In Nebraska the choice may vary considerably since many different crop types are grown. This discussion focuses on the factors that affect profitability, which are created by both biology and economics, and how that might be used to make the best crop rotation selection between corn and soybean cropping systems.

Agroecology In Canada: Towards An Integration Of Agroecological Practice, Movement, And Science, Marney E. Isaac, S. Ryan Isakson, Bryan Dale, Charles Z. Levkoe, Sarah K. Hargreaves, V.

College of Agriculture and Life Sciences Faculty Publications

This article surveys the current state of agroecology in Canada, giving particular attention to agroecological practices, the related social movements, and the achievements of agroecological science. In each of these realms, we find that agroecology emerges as a response to the various social and ecological problems associated with the prevailing industrial model of agricultural production that has long been promoted in the country under settler colonialism. Although the prevalence and prominence of agroecology is growing in Canada, its presence is still small and the support for its development is limited. We provide recommendations to achieve a more meaningful integration of …

Arabidopsis Tt8 Orthologue Of Pinto Bean (Phaseolus Vulgaris L.) Regulates Proanthocyanidin Genes And Seed Coat Darkening, Nishat Shayala Islam

Electronic Thesis and Dissertation Repository

Postharvest darkening of seed coat in pinto bean (Phaseolus vulgaris L.) is an undesirable trait that hinders its market potential. Darkening is more rapid in the cultivars like CDC Pintium than the newly developed slow darkening cultivar 1533-15. A single gene, SLOW DARKENING (Sd), is responsible for the slow darkening in pinto beans and the trait co-segregates with two simple sequence repeat (SSR) markers. The objective of this research is to identify and characterize the Sd gene to understand the slow darkening mechanism in pinto bean seed coat. A search for Sd within the linkage distance from …

Importance Of Being Digital Ready – What Does That Mean?, Charlotte Narjes

Cornhusker Economics

Communities often determine if they are digital ready on whether or not high speed internet is available. The conversation then focuses on who has high speed internet and who does not. Hence, the divide. High speed internet is an important factor on whether or not a community can be competitive in a global market. But, it is not the only digital-ready factor necessary to compete in a global economy. One challenge of focusing on the divide is that assumptions are made that individuals do not have skills in rural areas to use technology and, that these rural residents may not …

Phylogenomic Evidence For Ancient Recombination Between Plastid Genomes Of The Cupressus-Juniperus-Xanthocyparis Complex (Cupressaceae), Andan Zhu, Weishu Fan, Robert P. Adams, Jeffrey P. Mower

Department of Agronomy and Horticulture: Faculty Publications

Background: Phylogenetic relationships among Eastern Hemisphere cypresses, Western Hemisphere cypresses, junipers, and their closest relatives are controversial, and generic delimitations have been in flux for the past decade. To address relationships and attempt to produce a more robust classification, we sequenced 11 new plastid genomes (plastomes) from the five variously described genera in this complex (Callitropsis, Cupressus, Hesperocyparis, Juniperus, and Xanthocyparis) and compared them with additional plastomes from diverse members of Cupressaceae.

Results: Phylogenetic analysis of protein-coding genes recovered a topology in which Juniperus is sister to Cupressus, whereas a tree based on …

Rnai Targeting Of Manduca Sexta Using Chloroplast-Encoded Long Dsrna, William Burke

Electronic Thesis and Dissertation Repository

Pest management strategies are crucial for reducing insect crop damage, and methods with species-specific effect are particularly desirable. Expressing dsRNA with sequence complementarity to a vital gene of feeding pests is a strategy that has shown potential. I modified the chloroplast genome of cultivated tobacco, Nicotiana tabacum, by adding a sequence encoding a 2222 base pair dsRNA complementary to the vacuolar-type H⁺-ATPase subunit A mRNA of Manduca sexta and demonstrated expression of the product in leaves of the plants. Although feeding this same dsRNA that was synthesized in vitro to larvae knocked down expression of the target …

The Evolution Of Nebraska Corn Basis, Jessica J. Groskopf, Amanda Silva

Cornhusker Economics

In 2018 Nebraska farmers planted 9.7 million acres of corn, the most of any crop in the state. The primary uses for corn in the state are cattle feed and ethanol production. Nebraska currently has 25 ethanol plants producing around 2 billion gallons of ethanol annually. This capacity consumes approximately 40% of Nebraska’s annual corn production.

New Market Opportunities And Consumer Heterogeneity In The U.S. Organic Food Market, Gwanseon Kim, Jun Ho Seok, Tyler B. Mark

Agricultural Economics Faculty Publications

This paper investigates what factors and characteristics of organic consumers affect annual organic food expenditure by using Nielsen’s consumer panel dataset from 2010 to 2014. To be specific, this paper explores new marketing opportunities by investigating organic consumer heterogeneity in different household income levels by utilizing the multilevel model. Findings in this study will contribute to the previous and existing literature in three-folds. First, we find that the organic consumers are more heterogeneous in the high-level of income groups (approximately above $60,000), as well as the low-income households between $35,000 and $45,000. This finding demonstrates that the income levels above …

Wild, Native Bees And Managed Honey Bees Benefit From Similar Agricultural Land Uses, Elaine Evans, Matthew Smart, Dan Cariveau, Marla Spivak

Department of Entomology: Faculty Publications

Although both managed and unmanaged bees are important pollinators of crops and wild plants, efforts to address questions about landscapes that best support pollinators often focus on either wild pollinators or honey bees. This study examined if there was concordance between the success of wild bee communities and managed honey bee colonies at sites varying in floral availability and disturbance level in a predominantly agricultural landscape. We also determined which agricultural land uses best supported wild bee communities. The study area in the state of North Dakota in Northern Great Plains in North America is home to understudied native bee …
