Despite a century of genetic analysis, the evolutionary processes that have generated the patterns of exceptional genetic and phenotypic variation in the model organism Drosophila melanogaster remains poorly understood. In particular, how genetic variation is partitioned within its putative ancestral range in Southern Africa remains unresolved. Here, we study patterns of population genetic structure, admixture, and the spatial structuring of candidate incompatibility alleles across a global sample, including 223 new accessions, predominantly from remote regions in Southern Africa. We identify nine major ancestries, six that primarily occur in Africa and one that has not been previously described. We find evidence …


Engaging Farmers, Culinary Schools, And Communities In Value-Added Production To Strengthen Local Food Systems, Lauren B. Errickson, Ethan D. Schoolman, Virginia Quick, Sarah Davis, Anthony Capece Sep 2022

Engaging Farmers, Culinary Schools, And Communities In Value-Added Production To Strengthen Local Food Systems, Lauren B. Errickson, Ethan D. Schoolman, Virginia Quick, Sarah Davis, Anthony Capece

The Journal of Extension

Value-added products can generate farm income and improve community food access, yet lack of available kitchen infrastructure and labor can limit farm production capacity. This project explored how community-based culinary schools might fill the gap. A unique “product share” model was identified and piloted, meeting the collective needs of farmers, a culinary school, and urban consumers. By researching farmer crop availability and business model preferences, and aligning value-added production with community food preferences, we demonstrate a successful pilot indicative that similar initiatives can be replicated in other metropolitan areas, with potential to engage cross-disciplinary extension professionals.


Impact Of Major Emergencies On Food Security Risks, Cuihong Yang, Kang Lin, Xiang Gao Sep 2022

Impact Of Major Emergencies On Food Security Risks, Cuihong Yang, Kang Lin, Xiang Gao

Bulletin of Chinese Academy of Sciences (Chinese Version)

In recent years, the probability and frequency of international major emergencies are on the rise, which have threatened the global food security. The study decomposes the food supply chain into production section, consumption section, and circulation section; and then analyzes the risks of food security in each section when facing the major emergencies. In the production section, major emergencies restrict the inputs of labor and agricultural production materials, limiting food supply directly. In the consumption section, major emergencies usually increase the food price and decrease the resident income, and thus, decline the purchasing power of food and exacerbate the food …

Discussion On Approaches To Improving Soybean Supply Capacity In China, Feng Feng, Zhinan Zhang, Yongzhe Gu, Junpeng He, Zhixi Tian

Bulletin of Chinese Academy of Sciences (Chinese Version)

Soybean is one of the most important crops for food and oil. The soybean demand has been increased in recent years in China. Since China has limited soybean production capacity, it has been importing increasing amount of soybean from abroad. It is a critical topic for China to develop the soybean production and expand the import channels to ensure food security. Based on the soybean demand-supply situation from 2011 to 2020, this paper discussed the problems including severely insufficient domestic production and supply, high level of reliance on international supply, and limited import channels. It put forward suggestions on approaches …

Hybrid Incompatibility Between Ldrosophila Virilis And D. Lummei Is Stronger In The Presence Of Transposable Elements, Dean M. Castillo, Leonie C. Moyle Aug 2022

Hybrid Incompatibility Between Ldrosophila Virilis And D. Lummei Is Stronger In The Presence Of Transposable Elements, Dean M. Castillo, Leonie C. Moyle

Nebraska Extension: Faculty and Staff Publications

Mismatches between parental genomes in selfish elements are frequently hypothesized to underlie hybrid dysfunction and drive speciation. However, because the genetic basis of most hybrid incompatibilities is unknown, testing the contribution of selfish elements to reproductive isolation is difficult. Here, we evaluated the role of transposable elements (TEs) in hybrid incompatibilities between Drosophila virilis and D. lummei by experimentally comparing hybrid incompatibility in a cross where active TEs are present in D. virilis (TE+) and absent in D. lummei, to a cross where these TEs are absent from both D. virilis (TE−) and D. lummei genotypes. Using genomic data, …

Electronic Theses and Dissertations

The wild blueberry is one of the major crops of Maine, with significant economic value and potential health benefits. Due to global climate change, drought impacts have been increasing significantly in recent years in the northeast region of the USA, causing significant economic losses in the agricultural sectors. It has been predicted to increase further in the future. Changing patterns of the elevated atmospheric temperatures, increased rainfall variabilities, and more frequent drought events have made the wild blueberry industry of Maine vulnerable, suggesting the adoption of novel approaches to mitigate the negative impacts of global climate changes. Also, wild blueberry …


Modeling The Impact And Accelerating The Process Of Transitioning To A Sustainable Healthy Diet Through Decision Support Systems, Prince Agyemang Aug 2022

Modeling The Impact And Accelerating The Process Of Transitioning To A Sustainable Healthy Diet Through Decision Support Systems, Prince Agyemang

Graduate Theses and Dissertations

Food production and consumption are essential in human existence, yet they are implicated in the high occurrences of preventable chronic diseases and environmental degradation. Although healthy food may not necessarily be sustainable and vice versa, there is an opportunity to make our food both healthy and sustainable. Attempts have been made to conceptualize how sustainable healthy food may be produced and consumed; however, available data suggest a rise in the prevalence of health-related and negative environmental consequences of our food supply. Thus, the transition from conceptual frameworks to implementing these concepts has not always been effective. This paper explores the …

Consumer Preferences For Lab Grown Meat: The Effect Of Information On Consumer Choice, Aryn Blumenberg

Food Science Undergraduate Honors Theses

Global population growth and increased meat demand present challenges for the agricultural industry to produce meat sustainably. In-vitro meat (IVM) is an alternative that could reduce negative impacts associated with livestock production. The goal of this study was to examine consumers’ preferences for IVM. A choice experiment was created with twelve choice tasks that varied across five attributes: production method (IVM or conventional), carbon trust label, organic label, animal welfare label, and price. 1,120 US consumers were randomly assigned to one of four information treatments, differing by information presented regarding IVM: 1) neutral (baseline), 2) positive, 3) negative, and 4) …

Crosses between Drosophila simulans females and Drosophila melanogaster males produce viable F1 sons and poorly viable F1 daughters. Unlike most hybrid incompatibilities, this hybrid incompatibility violates Haldane’s rule, the observation that incompatibilities preferentially affect the heterogametic sex. Furthermore, it has a different genetic basis than hybrid lethality in the reciprocal cross, with the causal allele in Drosophila melanogaster being a large species-specific block of complex satellite DNA on its X chromosome known as the 359-bp satellite, rather than a protein-coding locus. The causal allele(s) in Drosophila simulans are unknown but likely involve maternally expressed genes or factors since the F1 …

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Our understanding of the science of anthropogenic climate change and its immediate and indirect impacts has grown within the last decade.Alongside anincrease in concern for the inequities within the industrialized food system, climate change is impacting agriculture and the communities that depend on it in myriad ways. These challenges have catalyzed investment in sustainable agriculture, “eat local” food movements, and rethinking of all aspects of food systems, including consumers, producers, retailers, and distributors. The body of literature on food systems primarily focuses on the connection between consumers and retailers; however, there is a notable absence of literature on the relationships …
