Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, 2019 Utah State University
Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom
All Graduate Theses and Dissertations
Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U ...

“For anyone who might be suffering from Anthropocene fatigue, this is a book to jolt you from your slumbers. What happens to the globe when we shift attention from the outward projection of emissions to extraction ? The Earth we thought we knew, and were already mourning, takes on a stunning new critical light.”—Claire Colebrook, Pennsylvania State University
Exterranean concerns the extraction of stuff from the Earth, a process in which matter goes from being sub- to exterranean. By bringing a rich archive of nonmodern texts and images from across Europe, into conversation with the contemporary work of Bruno Latour ...
Stability Analysis Of Kernel Quality Traits In Exotic-Derived Doubled Haploid Maize Lines, 2019 Iowa State University
Stability Analysis Of Kernel Quality Traits In Exotic-Derived Doubled Haploid Maize Lines, Adam Vanous, Candice Gardner, Michael Blanco, Adam Martin-Schwarze, Jinyu Wang, Xianran Li, Alexander E. Lipka, Sherry Flint-Garcia, Martin Bohn, Jode Edwards, Thomas Lubberstedt
Variation in kernel composition across maize (Zea mays L.) germplasm is affected by a combination of the plant’s genotype, the environment in which it is grown, and the interaction between these two elements. Adapting exotic germplasm to the US Corn Belt is highly dependent on the plant’s genotype, the environment where it is grown, and the interaction between these components. Phenotypic plasticity is ill-defined when specific exotic germplasm is moved over large latitudinal distances and for the adapted variants being created. Reduced plasticity (or stability) is desired for the adapted variants, as it allows for a more rapid ...

Planting Date, Hybrid Maturity, And Weather Effects On Maize Yield And Crop Stage, 2019 Iowa State University
Planting Date, Hybrid Maturity, And Weather Effects On Maize Yield And Crop Stage, M. E. Baum, S. V. Archontoulis, M. A. Licht
Unfavorable weather conditions frequently cause farmers to plant maize (Zea mays L.) outside the optimum planting timeframe. We analyzed maize yield and phenology from a multilocation, year, hybrid relative maturity, and planting date experiment performed in Iowa, USA. Our objectives were to determine the optimum combination of planting date and relative maturity to maximize maize grain yield per environment and to elucidate the risk associated with the use of “full-season hybrids” when planting occurs beyond the optimum planting date. Analysis of variance (ANOVA) attributed 70% of the variability in grain yield to planting date and only 10% to relative maturity ...

Koziel
Agricultural and Biosystems Engineering Publications
The Midwest wine industry has shown a marked increase in growers, hectares planted, wineries, and wine production. This growth coincides with the release of cold-hardy cultivars such as Brianna and Frontenac gris, in 2001 and 2003, respectively. These white grape varieties account for one-third of the total area grown in the state of Iowa. It is generally accepted that the wine aroma profile plays a crucial role in developing a local, sustainable brand. However, the identity of Brianna/Frontenac Gris-based wine aromas and their link to the grape berry chemistry at harvest is unknown. This study aims to preliminarily characterize ...

Multi-Tactic Ecological Weed Management In A Changing Climate, 2018 University of Maine
Multi-Tactic Ecological Weed Management In A Changing Climate, Sonja K. Birthisel
Electronic Theses and Dissertations
Climate change is expected to impact weed communities in Maine, and the efficacy of tools and tactics farmers use to manage them. Through seedbank sampling and surveys of Maine organic farms, we identified currently rare weeds that are known to be especially abundant or problematic in warmer areas of the USA and might therefore represent an emerging agronomic risk. Many ecological weed management strategies that focus on depleting the weed seedbank are expected to remain effective in a changing climate, and become increasingly important as efficacy of cultivation and some herbicide applications diminish or become more variable. Through field experiments ...
Living Shoreline Stabilization To Increase Resiliency At De Soto National Memorial, 2018 University of Central Florida
Living Shoreline Stabilization To Increase Resiliency At De Soto National Memorial, Linda Walters, Melinda Donnelly, Christian Pilato, Suzanne Connor
CEELAB Research Data
De Soto National Memorial (Bradenton, FL) is an important location where both Native Americans and De Soto's army of soldiers once lived. We have been working closely with the National Park Service and the University of Central Florida to understand how to best stabilize this shoreline using living shoreline techniques combined with long-term natural recruitment. Stabilizing De Soto's shoreline is essential to decrease erosion and shoreline loss to protect the Park's cultural and natural resources, especially the numerous historically significant shell middens. Through pre-restoration monitoring, we determined that high-energy boat wakes were limiting natural mangrove recruitment. Lack ...

School of Forest Resources and Environmental Science Publications
Using time-series transcriptomic data from poplar roots undergoing polyethylene glycol (PEG)-induced drought stress, we built a genetic network model of the involved putative molecular responses. We found that the network resembled a hierarchical structure. The highest hierarchical level in this structure is occupied by 9 genes, which we called superhubs because they were primarily connected to 18 hub genes, which are then connected to 2,934 terminal genes. We were only able to regenerate transgenic plants overexpressing two of the superhubs, suggesting that the majority of the superhubs might interfere with the regeneration process and did not allow recovery ...
Rhizosphere Microbial Communities Of Spartina Alternifloa And Juncus Roemerianus From Restored And Natural Tidal Marshes On Deer Island, Mississippi, 2018 University of Southern Mississippi
Rhizosphere Microbial Communities Of Spartina Alternifloa And Juncus Roemerianus From Restored And Natural Tidal Marshes On Deer Island, Mississippi, Olga Mavrodi, Carina M. Jung, Jed O. Eberly, Samuel Hendry, Sanchirmaa Namijilsuren, Patrick D. Biber, Karl J. Indest, Dmitri V. Mavrodi
The U. S. Gulf of Mexico is experiencing a dramatic increase in tidal marsh restoration actions, which involves planting coastal areas with smooth cordgrass (Spartina alterniflora) and black needlerush (Juncus roemerianus) for erosion control and to provide habitat for fish and wildlife. It can take decades for sedimentary cycles in restored marshes to approach reference conditions, and the contribution of the sediment microbial communities to these processes is poorly elucidated. In this study, we addressed this gap by comparing rhizosphere microbiomes of S. alterniflora and J. roemerianus from two restored marshes and a natural reference marsh located at Deer Island ...
Suberin Biosynthesis And Deposition In The Wound-Healing Potato (Solanum Tuberosum L.) Tuber Model, 2018 The University of Western Ontario
Suberin Biosynthesis And Deposition In The Wound-Healing Potato (Solanum Tuberosum L.) Tuber Model, Kathlyn Natalie Woolfson
Electronic Thesis and Dissertation Repository
Suberin is a heteropolymer comprising a cell wall-bound poly(phenolic) domain (SPPD) covalently linked to a poly(aliphatic) domain (SPAD) that is deposited between the cell wall and plasma membrane. Potato tuber skin contains suberin to protect against water loss and microbial infection. Wounding triggers suberin biosynthesis in usually non-suberized tuber parenchyma, providing a model system to study suberin production. Spatial and temporal coordination of SPPD and SPAD-related metabolism are required for suberization, as the former is produced soon after wounding, and the latter is synthesized later into wound-healing. Many steps involved in suberin biosynthesis remain uncharacterized, and the mechanism ...

Risks And Opportunities Of Gm Crops: Bt Maize Example, Andrea K. Carzoli, Siddique I. Aboobucker, Leah L. Sandall, Thomas T. Lubberstedt, Walter P. Suza
The anticipated world population growth emphasizes a need to produce more food on less land. Cutting-edge technologies, including genetic engineering, can help to develop improved crop varieties and protect natural resources. In spite of the potential for genetically-modified (GM) crops to make crop production more efficient, they remain a polarizing issue due to safety concerns. This paper provides an overview of the risk assessment process. The safety of Bacillus thuringiensis (Bt) proteins is used as an example for how risk assessment is applied to GM crops. Risks associated with GM crops have proven to be low to non-existent. Developing countries ...

Understanding Spatial Dynamics Of Tallgrass Prairie Dominated By Tall Fescue, Callie Griffith
Theses, Dissertations, and Student Research in Agronomy and Horticulture
This study was conducted on restored tallgrass prairie and invaded tallgrass prairie located in the Grand River Grasslands of southern Iowa to determine differences in heterogeneity of plant structure and functional group composition at different scales. Restored tallgrass prairies were seeded with a species-rich seeding mixture and managed by burning the entire prairie, every three years. Data were collected in August 2014 and 2015 to compare heterogeneity of restoration of native plant structure and functional group composition to the heterogeneity of invaded tallgrass prairies that were managed with patch burning and conventionally grazed. Invaded tallgrass prairies were managed with patch-burning ...
Ripeness Attributes Of Arkansas-Grown Peaches And Nectarines At Harvest And During Postharvest Storage, 2018 University of Arkansas, Fayetteville
Ripeness Attributes Of Arkansas-Grown Peaches And Nectarines At Harvest And During Postharvest Storage, Mary Siebenmorgen
Food Science Undergraduate Honors Theses
Evaluating ripeness attributes of peaches and nectarines helps determine feasibility for commercial markets. Five cultivars (Amoore Sweet, Bowden, Bradley, Effie, and Souvenirs) and five breeding selections (A-663 CN, A-794 CN, A-811 CN, A-819, and A-885) were hand harvested in 2017 from the University of Arkansas System Division of Agriculture’s Fruit Research Station in Clarksville, AR. The tree-ripened fruit was evaluated at harvest (day 0), and commercially-ripened fruit (ripened during storage) was evaluated at 0, 7 and 14 d storage at 4° C. The attributes of tree and commercially-ripened fruit varied at harvest and included chlorophyll (0.04-0.86 abs ...
