Foliar Application Of Acetic Acid And Effectiveness Against Drought At Different Time Points In Soybean Development, Miranda Rudolph

Scholars Week

Abstract

Drought is arguably the most serious environmental factor affecting crop production today. A plants response to drought stress is extremely complex, affecting numerous metabolic pathways that are all interconnected in their responses. Due to this complex nature, scientists do not fully understand the implications of different treatments and how they affect these processes. Acetic acid has been shown to improve plant growth and resistance to drought stress, but exactly how it accomplishes this is also unknown. Soybeans (Glycine max) are one of the most important crops worldwide and can suffer significant yield loss due to drought stress. As climate …

My Summer Working With Two-Spotted Spider Mites, Renée A. Smith

Undergraduate Student Research Internships Conference

Two-spotted spider mites are a polyphagous pest, capable of eating a magnitude of food crops which causes a large problem for Canadian agriculture. Their ability to consume various crops stems from their ability to adapt to various chemical defence mechanisms. This ability allows them to acquire resistance to many commonly used pesticides. This has resulted in large infections in Canadian farms with few options to prevent the pests from affecting crop yields. Take a look at my project if you'd like to see how the Grbic lab is working to combat this issue using genetic engineering techniques!

A Qualitative Look Into Repair Practices, Jumana Labib

Undergraduate Student Research Internships Conference

This research poster is based on a working research paper which moves beyond the traditional scope of repair and examines the Right to Repair movement from a smaller, more personal lens by detailing the 6 categorical impediments as dubbed by Dr. Alissa Centivany (design, law, economic/business strategy, material asymmetry, informational asymmetry, and social impediments) have continuously inhibited repair and affected repair practices, which has consequently had larger implications (environmental, economic, social, etc.) on ourselves, our objects, and our world. The poster builds upon my research from last year (see "The Right to Repair: (Re)building a better future"), this time pulling …

Clearing The Air Between Methane And Commercial Beef Cattle In Ireland, Clodagh V. Ryan

ORBioM (Open Research BioSciences Meeting)

Background

Rumen methanogenesis is the single most significant source of anthropogenic methane (CH₄) emissions. This research aimed to analyse CH₄ data recorded by GreenFeed systems by assessing the repeatability of such phenotypic measures, estimating the heritability of CH₄, and generating CH₄ estimated breeding values (EBVs) for inclusion in the national breeding index_.

Methods

CH₄ measurements were recorded on 979 cattle for 20 to 83 days using GreenFeed machines, resulting in 211,136 individual CH₄ observations. The phenotypic repeatability of CH₄ was estimated for six different averaging periods using a linear mixed …

Validation Of The Irish National Sheep Genetic Evaluations, Niamh Barry

ORBioM (Open Research BioSciences Meeting)

Background: In Ireland, national sheep genetic evaluations have been implemented since 2009, however, to date no large scale study has been undertaken to investigate the accuracy of genetic evaluations in a large multi-breed population. The aim of this study was to validate the estimated breeding values (EBV) on a range of traits, using national data comprising 203,469 records across a range of phenotypic traits from 9,377 flocks.

Methods: The association between direct and maternal EBV on a range of lamb growth traits was quantified using a fixed effects model. For the lambing traits the association between direct and maternal EBV …

An Investigation Of The Novel Use Of Bacteriophages To Diagnose And Treat Johne's Disease In Cattle, Max Kevane-Campbell

ORBioM (Open Research BioSciences Meeting)

Johne’s disease is a scourge to dairy farmers all over the world. It is an infectious disease that causes chronic inflammation and lesions along the inside of the small intestine of, primarily, ruminant animals (i.e., cattle and sheep). It is an incurable disease and urgently requires new and radical intervention strategies. Apart from careful on-site farm management practices, little can be offered to farmers to reduce the risk of infection, and nothing short of livestock culling is effective once an animal becomes infected. Currently, there are no vaccines licensed in Ireland or antibiotic treatment strategies available for Johne’s disease. This …

Promoting Ecosystem Services By Implementing Agroforestry, Martin L. Emerson

Ideas: Exhibit Catalog for the Honors College Visiting Scholars Series

A recent proposal to enhance the sustainability of agriculture is agroforestry, the practice of integrating trees into farmland. This technique can be analyzed through the ecosystem services model, which describes the interrelatedness of natural land, managed land, producers, and consumers. Agroforestry could shelter crops from the adverse weather conditions as well as provide habitat for wildlife. On the other hand, implementing agroforestry would also entail the drawback of a substantial upfront cost. Environmental scientists propose that efforts to reinforce ecosystem services could play a significant role in mitigating the effects of global environmental change on agriculture.

Digging Into Sustainable Agriculture, Gabrielle I. Tanner

Ideas: Exhibit Catalog for the Honors College Visiting Scholars Series

Between climate change and increasing global populations, humanity has reached a critical moment for agriculture. The push to produce more food has resulted in declining ecosystems and a diminishing crop biodiversity. Experts propose shifting towards sustainability to protect and augment natural ecosystem services, upon which agriculture depends. Widespread implementation of practices such as cover cropping and green manures have the potential to reduce waterway pollution and climate change while preserving the biodiversity that allows agroecosystems to be resilient against threats like pests. Ultimately, an agricultural revolution such as this is necessary in the effort to feed humanity in the future.

Community Responses To Food Insecurity During Covid-19: A Case Study In Sheffield, England, Nicole Kennard

Urban Food Systems Symposium

The COVID-19 pandemic gave rise to a group of newly food insecure people and deepened hardship for those already food insecure. The crisis disrupted national food supplies and created challenges to accessing and utilizing the food that was available. As financial struggle deepened for people, and some became unable to shop for food or cook due to isolation requirements and illness, many turned to community organizations to obtain food. In Sheffield, England, small community food organizations soon became the leaders of the city’s emergency food response. One such organization is the Foodhall Project, a community food organization which had previously …

The Biggest Grower - A Youth Gardening Competition For Growing Specialty Crops And Urban Farmers, Stacy A. Adams, Terri James

Urban Food Systems Symposium

Youth today have tendencies for unhealthy lifestyles, being sedentary, consuming high fat diets low in fruits and vegetables, all contributing to child obesity, type 2 diabetes, hypertension, and precedence for life-long health concerns. School lunch programs provide opportunity for youth to consume balanced diets but does not make a significant change in lifestyle. Research has identified that youth participating in gardening at home were positively impacted with making lasting healthy choices by improved knowledge and garden connection. For rural and economically disadvantaged urban households, poor diet is directly attributed to the inaccessibility of fresh produce, affordability and understanding of preparation …

Biodiversity Loss In Our Ecosystems Results In Increased Food Insecurity, Kyler A. Bartol

Ideas: Exhibit Catalog for the Honors College Visiting Scholars Series

Food security has always been a pressing issue in both our country and across the world. Recently, our food security has become at risk, and one main cause of this is the loss of biodiversity in our ecosystems. Dr. Alison Power has worked extensively with the legume plants in Ethiopia, and she has seen firsthand how their farming techniques have preserved biodiversity. Current research methods focus on alternative agricultural methods in order to protect biodiversity and keep our food secure.
