Ain't No Sunshine When They're Gone: Pollinators In A Solar Prarie, Brigid M. Morgan
Ain't No Sunshine When They're Gone: Pollinators In A Solar Prarie, Brigid M. Morgan
Honors Theses
Around the world, pollinator populations are decreasing due to climate change, habitat loss and fragmentation, invasive species, pesticide use, and disease. A solar prairie can provide that habitat space with native plants to attract and promote the growth of native pollinator populations. In this study at the University of Dayton in Dayton, Ohio, I sought to find out if native pollinators were using the habitats inside and around the solar panels at Curran Place. By using pan traps weekly throughout the summer months to collect the insects, I found that native pollinators are using the habitats between the rows of …
A Starling In A Pear Tree: Assessing The Influence Of Bird Dispersal On Callery Pear (Pyrus Calleryana), Olivia Clark
A Starling In A Pear Tree: Assessing The Influence Of Bird Dispersal On Callery Pear (Pyrus Calleryana), Olivia Clark
Honors Theses
Invasive species can disrupt ecosystems and negatively affect other species. Callery pear (Pyrus calleryana) is an invasive ornamental tree that is spreading quickly throughout the United States. It is possible that birds are responsible for spreading Callery pear by eating the fruit and depositing seeds in new areas. European starlings (Sturnus vulgaris) and American robins (Turdus migratorius) are mentioned in most studies as responsible for the dispersal of Callery pear. However, there is also evidence that Cedar waxwings (Bombycilla cedrorum) also feed on the tree. Invasive plants can impact avian health, reproduction, and migration. Additionally, there are many aspects of …
The Impact Of Anaerobic Exposure And Propionate On The Kinetics And Pathogenesis Of Listeria Monocytogenes, Mackenzie T. Martin
The Impact Of Anaerobic Exposure And Propionate On The Kinetics And Pathogenesis Of Listeria Monocytogenes, Mackenzie T. Martin
Honors Theses
Listeria monocytogenes is a foodborne pathogen commonly found in ready-to-eat deli and dairy products. This foodborne pathogen is responsible for the disease listeriosis, which disproportionately impacts immunocompromised individuals. This research aims to evaluate how natural intestinal environments influence the pathogenesis of Listeria. One particular environmental condition that has a well-documented effect on Listeria is varying levels of oxygen. Specifically, anaerobic exposure during the growth of Listeria greatly impacts subsequent intracellular pathogenesis. When grown and adapted under anaerobic conditions, Listeria overall exhibits decreased intracellular survival and decreased cell to cell spread. However, the presence of propionate, a natural byproduct of fermentation …
Establishing A Drosophila Colon Cancer Model To Study Interactions And Therapeutic Targets Of Oncogenic Pathways, Kathleen T. Mccaslin
Establishing A Drosophila Colon Cancer Model To Study Interactions And Therapeutic Targets Of Oncogenic Pathways, Kathleen T. Mccaslin
Honors Theses
The objective of this project is to develop an in vivo colorectal cancer (CRC) model in Drosophila melanogaster to test the role of Ras and Wnt pathways in gastrointestinal cancer as potential therapeutic targets. To do so, we have (a) developed a CRC model in flies, (b) tested the levels of Ras and Wnt pathway activity in this model, and (c) will use drugs to find inhibitors of these pathways. Using fly mutants and transgenic flies we have created small patches of cancerous cells in the fly intestine in which have activated oncogenic Ras (mutation RasV12) and dominant negative p53 …
