Developing A Novel Place Preference Assay To Compare Drosophila Species Over Time, Martha M. Brinson May 2022

Developing A Novel Place Preference Assay To Compare Drosophila Species Over Time, Martha M. Brinson

Honors Theses

Across phylogeny, integration of external factors, memory, and internal states of the organism dictate organismal behavior and mechanisms. The underlying genetic components can affect these behaviors such as in genomic changes arising from speciation. In this thesis, a new place preference assay was evaluated in the analysis and investigation of two species of Drosophila flies (D. melanogaster and D. simulans) to measure similarities and differences and their attraction to two different food substrates. Sleep and circadian measurements were also recorded during experimentation. The Drosophila Activity Monitor 5M (DAM5M) System and Sleep Circadian Analysis MATLAB Program (SCAMP) analysis were …


Investigation Of The Effects Of Resveratrol And Epigallocatechin Gallate On Woodsmoke-Induced Inflammation, Sarenna Naomi Enright Apr 2022

Investigation Of The Effects Of Resveratrol And Epigallocatechin Gallate On Woodsmoke-Induced Inflammation, Sarenna Naomi Enright

Honors Theses

Until a few years ago, most scientific investigations related to the health effects of air pollution focused on outdoor air pollutants. But in recent years, the concerns over indoor air pollution has increased. People can spend up to 90% of their time in indoor environments, especially their homes, even more so since the beginning of the COVID-19 pandemic. The concentrations of some air pollutants are five times higher than what is found outdoors.

Indoor air pollution exposure remains a significant cause of morbidity and mortality worldwide. Approximately half of the global population is exposed to abnormally high concentrations of household …


Modeling Jadera Haematoloma’S Phenotypic Variation In The Context Of Its Developmental Plasticity, Michael C. Yorsz Jan 2022

Modeling Jadera Haematoloma’S Phenotypic Variation In The Context Of Its Developmental Plasticity, Michael C. Yorsz

Honors Theses

Phenotypic plasticity is the ability of an organism to integrate information from environmental cues to inform the development of its phenotype and remains understudied in biology. Models of plasticity are needed because evolution in the presence of plasticity is poorly understood. Jadera haematoloma, a hemimetabolous true bug, is an excellent animal model of plasticity, exhibiting a non-linear plastic response to juvenile nutrition that biases adult development into groups with differences in flight capability, wing shape, and fecundity. However, there is a lack of literature consensus regarding the range of developmental outcomes in the species. Some publications report the presence …


Can Gdp Be Predictive Of Fertility Rates In Sweden?, Hannah Coleman Jan 2022

Can Gdp Be Predictive Of Fertility Rates In Sweden?, Hannah Coleman

Honors Theses

Fertility rates in a country vary and can be influenced by numerous different aspects of an individual’s life and the society in which they live. One aspect that may influence fertility rates at the national level is the gross domestic product (GDP). GDP is an indicator of a country’s economic productivity. Because fertility is linked to both economic development and individual resources, GDP may be a useful indicator of fertility rates. If so, knowing or predicting GDP could be used to project the fertility rates of a population years into the future. To determine if a reasonable connection between GDP …
