Library/Life Sciences Undergraduate Poster Competition 2023
We are interested in detecting the absence or rate of multiple paternity within mule deer populations (Odocoileus hemionus) due to 1) their unique breeding system where males mate-guard females from other males[2], and 2) the highly skewed male-biased sex ratios in populations as a result of harvest management. Comparing the rate of multiple paternity to sex ratio will suggest if harvest management is influencing long-term population genetics.

Deep brain photoreceptors (DBPs) are light sensing neurons present in mammals and non-mammalian vertebrates. In non-mammalian vertebrates, studies have shown DBP involvement in various time and light dependent behaviors including circadian rhythm, phototaxis, and seasonal reproduction. In adult teleosts, DBPs are present throughout the brain, including the optic tectum (OT). While their approximate location in teleosts is known, DBP’s function is relatively unknown. In this study, we focused on DBPs present in the larval zebrafish OT, a multilaminated midbrain structure responsible for multisensory integration. Single-cell RNA sequencing of the larval zebrafish OT showed the presence of several opsins. We focused …

The structural organization of DNA in eukaryotic cells is greatly implicated in the regulation of gene expression and thus cellular properties and behavior. At the most fundamental unit of this organization, ~147 bp of DNA wraps 1.7 times around a histone octamer core, forming a collective unit called the nucleosome. The positioning and occupancy of these nucleosomes around the promoter elements of genes is known to be a strong regulator of transcription in eukaryotic nuclei, and post-translational modifications (PTM’s) to the protruding N-terminal tails of histone proteins are known to influence chromatin structure and thus gene expression; however, relatively little …
