Nutrient availability is a key factor in determining the productivity of an ecosystem. The concentration of nutrients such as nitrogen and phosphorus is regulated by several mechanisms within the soil including their interactions with one another. These mechanisms, often referred to as co-limitation or stepwise co-limitation, often allow the availability of one nutrient to either […]
C37: Investigating the Efficiency of Nitrogen Fertilizer
Our research focuses on finding the most efficient fertilizer with the least environmental impact while still producing a high crop yield that incorporates the field of agriculture, environmental studies and business. We conducted our research by searching for information within published work. We used websites like the Web of Science and Google Scholar to find […]
C55: Mice Behavior: Altering Purkinje Neurons Within the Cerebellum
Intracellular fibroblast growth factor 12 (Fgf12) is expressed throughout the central nervous system and is known to bind and regulate voltage-gated sodium channels. Sodium channels are critical for the formation and propagation of neuronal action potentials. Fgf12 has also been identified as a locus of mutations underlying epileptic encephalopathy (EIEE) and sudden unexpected death in […]
C63: Growth Rates and Body Stoichiometry of Juvenile Piscivorous Fish Differ Based on Dietary Phosphorus Content
The primary focus of this research project was on fish ecology and physiology. While most some animals can be flexible in terms of their body stoichiometry, the mechanism by which dietary nutrient content affects fish body stoichiometry and growth is still poorly understood, particularly for piscivores (fish who eat other fish). To better understand these […]
C70: Transposition of Mutator Transposons Increases Recombination Frequency in Maize
Meiotic recombination is an important phenomenon that results in genetic diversity and accurate segregation of homologous chromosomes. Mishaps in meiotic recombination can have severe consequences in humans, including pregnancy loss, congenital disorders, and other genetic diseases. In all eukaryotes, meiotic recombination is initiated by double-stranded breaks (DSBs) and is finished by the repair of those […]
C71: Investigating the Effects of Sex on Meiotic Recombination in Maize Hybrids
Meiotic recombination ensures the accurate segregation of homologous chromosomes and reshuffles genetic information to generate new combinations of alleles. The rate of meiotic recombination differs between species and is even different between male and female meiosis of the same species. Sex differences have important consequences for population differentiation, sex chromosome evolution, adaptation, and speciation. While […]
B42-P: Changing Ecosystem Dynamics: Identifying potential impacts of marine invasion
During the Late Ordovician (Katian) in the Cincinnati Series of North America, shallow marine ecosystems flourished and remained stable for several million years. Previously isolated ocean basins in the surrounding regions connected due to a sea level rise, leading to an influx of non-native species termed the Richmondian Invasion (RI). The Cincinnati Series thus preserves […]
C42-P: Transcriptomic Analysis for the Whole Lens of PTEN Knockout Mice
Phosphatase and tensin homolog (Pten) is a tumor suppressor gene that is knocked out or mutated in many cancers. Additionally, knocking out this gene in mice causes cataracts and other developmental issues with the lens. This project involves analyzing differential gene expression in the form of RNAseq data encompassing the entire transcriptome of the lens […]
B52-P: Minds Made Up: The Intersectionality Between Medical Decision Making and COVID-19
Contact Tracing explores the public health response to COVID-19 and the psychology of the medical decisions that are made as they pertain to communicating with and abiding by contact tracing efforts. This is accomplished through an anthropological approach to critically examine the implications of contact tracing, taking into account several nuances that encompass the spread […]
B56-P: COVID-19 in the Heart and the Nervous System
The COVID-19 virus is known to have various effects on the body, both long and short term. This project, an assignment for BIO 203W: Introduction to Cell Biology, examines the effects of COVID on the heart and the nervous system. Information was sourced from news articles and journals through the Miami University library system, with […]
